SYSTEM FOR CONTINUOUS CAKY STARTER PRODUCTION AND
METHOD FOR MAKING CAKY STARTER
TECHINAL FIELD
The disclosure relates to the field of caky starter production, and particularly to a system for continuous caky starter production and a method for making caky starter.
BACKGROUND ART
A starter of fen-flavor liquor has saccharifying and fermentation alcohol production functions in a liquor making process. In addition, metabolic products of more than twenty kinds of microorganisms included in the starter directly determine a flavor and style of the liquor. Therefore, it is necessary to reasonably select a starter making method to provide a good fermentation environment for growth and reproduction of mold hyphae and the microorganisms, so as to ensure mouth-feel of the fen-flavor liquor. Starter is the key of liquor, and quality of a caky starter has direct influence on a fermentation condition and liquor making quality. In a starter making process, factors such as a thickness, air permeability and water content of a caky starter all have great influence on quality of the caky starter.
In the liquor making industry in China, a caky starter making process goes through two stages of manual starter making and automatic starter stamping, wherein automatic starter stamping is improved greatly compared with manual starter stamping, and has become a main making process at present. For automatic starter stamping methods, starter stamping methods used by distilleries in China at present mainly include hydraulic starter stamping, pneumatic starter stamping and mechanical starter stamping. The three starter stamping manners are specifically analyzed as follows.
(1) Mechanical starter stamping: in this starter stamping manner, power is provided by a motor, a gear and a chain are utilized for joint transmission, and a connecting rod and an eccentric mechanism are utilized to perform upward and downward reciprocating movement to complete stamping actions over caky starters.
A die box completes its movement and positioning actions under the coaction of a cam, a lever and a grooved wheel. When a starter hammer presses down, the die box stops moving; and when the starter hammer moves upwards, the die box moves forward by a die box position for next cyclic stamping. Production efficiency of this starter stamping manner is 700-1,000 starters/hour. This starter stamping manner adopts a multiple-forming process, and no special feeding mechanism is required to be arranged. The pressed caky starters are uniform in internal and external compactness, and moreover, a good syrup purification effect is achieved. At present, most of distilleries adopt this starter stamping manner. However, this starter stamping manner has the shortcomings of requirement on human assistance in feeding, non-uniform feeding, non-uniform thicknesses of the caky starters, complex transmission of the die box, high failure rate and the like during use. In addition, water for cleaning the die box may not be recycled, so that water resources are seriously wasted.

(2) Pneumatic starter stamping: in this starter stamping manner, power is obtained from compressed air, a pneumatic static pressure forming method is adopted, operations of feeding, blank pressing, ejection and the like are completed through three hand-operated reversing valves, and production efficiency is 350-500 starters/hour. However, this starter stamping manner still adopts an one step-forming method, and also has the shortcomings of the one step-forming method.
Meanwhile, this pneumatic starter stamping equipment has the shortcomings of difficulty in maintenance, loud noise of an air pump and relatively low production efficiency, and thus is used less by distilleries at present.

(3) Hydraulic starter stamping: in this starter stamping manner, power is provided by a hydraulic system, a gear pump is driven by a motor to rotate so as to convert electric energy into pressure energy of oil, and then the pressure energy is converted into mechanical energy for output through a hydraulic oil cylinder, thereby completing operations of stamping of caky starters, ejection of the caky starters and output of the caky starters. The above actions are mainly completed by a stamping oil cylinder, ejection oil cylinder and feeding oil cylinder arranged on a stand respectively, moreover, each of the three oil cylinders is driven by a gear pump driven by an asynchronous motor, and production efficiency usually reaches 250-600 starters/hour. This starter stamping manner adopts an one step-forming method, and thus has the shortcomings that the caky starters are externally compact and internally loose, the hydraulic system is difficult to overhaul and maintain and the like. In addition, feeding and starter pressing operations in this mechanical starter stamping manner are completed in different steps, and a special delayed belt conveyor is required to be equipped for the starter pressing operation, so the production efficiency is not high. Moreover, equipment occupies a large area, and its construction cost is also very high.
Along with continuous increase of market requirements on liquor in China, production capabilities of existing discontinuous caky starter production systems adopted by distilleries may not meet the market requirements. Moreover, the existing discontinuous caky starter production systems have the following shortcomings.
(1) A ratio of a starter material to water is unstable. A water addition link of an existing starter material stirring system completely adopts a conventional empirical method, that is, a magnitude of water supply is manually controlled by experience, and then individual differences of workers may make the ratio of the starter material to water after stirring unstable, thereby seriously influencing quality of liquor.
(2) A starter material feeding system is unstable. A feeding system of existing starter making equipment does not solve non-uniformity of a weight of a starter material reaching the die box, and adoption of a semiautomatic feeding manner causes serious waste of the starter material in a feeding process and substandard weights of caky starters. Due to the substandard weights of the caky starters, exhaust performance of the caky starters, distribution of batter and compaction balance in a fermentation process of the caky starters may not meet production requirements.
(3) A clearance between the die box and hammerhead is overlarge. The clearance between the die box and hammerhead of the existing caky starter production system is at least 2mm. In a process of pressing the starter material by the hammerhead, an overlarge clearance may cause such a condition that the starter material overflows from an edge by extrusion approximate to 20KN to cause waste of the starter material and difficulty in control over the weights of the caky starters, so that the quality of the pressed caky starters may not be ensured in the fermentation process.

(4) Water resources are seriously wasted. The die box of the existing caky starter production system is cleaned with approximately 20 tons of water every day, and in addition, the water produced after cleaning the die box contains a large amount of microorganisms favorable for fermentation of the caky starters. However, the cleaning water in the system is directly discharged as sewage, so that not only are the water resources greatly wasted, but also rich microorganisms in the cleaning water are wasted.

(5) There exist problems about sanitary and safety of the caky starters, and an equipment maintenance rate is high. Moreover, oil is required to be injected for lubrication during operation, and the lubricating oil may easily drip into the die box, thereby contaminating the quality of the caky starters and even influencing quality of fen-flavor liquor.

DETAILED DESCRIPTION OF THE INVENTION
The technical solutions of the disclosure will further be described below through the drawings and embodiments in detail.
FIG. 1 is a schematic diagram of the principle of an embodiment of a system for continuous caky starter production according to the disclosure. In combination with specific compositions of the system for continuous caky starter production shown in FIG. 3-FIG. 9, the system for continuous caky starter production of the embodiment includes: a starter making equipment 100, a starter material supply mechanism 200, a water cleaning and recycling system 300 and a measurement and control device 400.
The starter making equipment 100 is arranged to fill a die box 161 with a received starter material, repeatedly stamp the starter material in the die box 161 at multiple positions in a hydraulic driving manner to form a caky starter, and then demold and discharge the caky starter. The starter material supply mechanism 200 is arranged to mix and stir a fed dry material and water to form the starter material, and convey the formed starter material to the starter making equipment 100. The water cleaning and recycling system 300 is arranged to clean an empty die box 162 after the demolding in the starter making equipment 100, and recycle wastewater produced after the cleaning. The measurement and control device 400 communicatively connects with the starter making equipment 100, the starter material supply mechanism 200 and the water cleaning and recycling system 300, and is arranged to control a conveying process of the dry material and water, a continuous pressing process of the starter material, a die box cleaning process and a wastewater recycling process according to sensing signals in the starter making equipment 100, the starter material supply mechanism 200 and the water cleaning and recycling system 300.
According to the embodiment, for the shortcomings of an existing discontinuous caky starter production system, a modular design concept is adopted for design in the disclosure, and the measurement and control device is introduced to control and coordinate process actions of the conveying process of the dry material and water, the continuous pressing process of the starter material, the die box cleaning process, the wastewater recycling process and the like according to the sensing signals in the starter making equipment, the starter material supply mechanism and the water cleaning and recycling system, so that caky starters may be continuously produced, and caky starter production efficiency and output quality are greatly improved. For the measurement and control device, a Programmable Logic Controller (PLC) control technology may be adopted, so that a system control process is more convenient and higher in automation degree.
By long-term exploration and trying, fen-flavor liquor brewers conclude a seven-stamping starter making process. Therefore, compared with an existing mechanical starter stamping manner, the starter making equipment in the embodiment adopts a manner of uniformly stamping the starter material in the die box for many times (for example, seven times) at the multiple positions under hydraulic driving, and such manner may ensure that a starter pressing force is kept as constant as possible and ensure that hardness of the caky starter is within a predetermined range to reduce adverse impact on a caky starter fermentation effect. In addition, compared with the existing caky starter production system which consumes a large amount of water when the die box is cleaned, the water cleaning and recycling system in the embodiment may recycle the wastewater produced after the cleaning, so as to effectively save water resources.
There are three important links in a starter making process: first, how to control a mixing ratio of powder and water; second, how to uniformly stir powder of several grains and water; and third, how to press the starter material with high air permeability. The three links will be described in detail hereinafter, respectively.
FIG. 2 is a specific process based on an embodiment of a system for continuous caky starter production of the disclosure. The process will be described below, including the following contents.
The crushed dry material (usually some fermentable dry food materials) for forming the starter material and water are conveyed to the equipment capable of implementing stirring of the starter material respectively, and water and the dry material are stirred to form the starter material. After the starter material is formed, the starter material is conveyed to the die box for a loading operation. The block-extruded starter material (i.e., the caky starter) is discharged from the die box loaded with the starter material after stamping forming and caky starter demolding.
For the empty die box from which the caky starter has been discharged, a die box cleaning step is required to enable the empty die box to meet a loading requirement. In this process, the measurement and control device implements overall process control over multiple process links such as conveying and stirring of raw materials, box loading, stamping and demolding of the starter material, discharge of the caky starter and cleaning of the die box, and proper detection links and control algorithms may be added according to a process requirement to ensure that each process action may be continuously and coordinatively executed under a set objective.
FIG. 3 is a front schematic diagram of the structure of a starter making equipment in an embodiment of a system for continuous caky starter production according to the disclosure. In combination with a top schematic diagram of the structure of the starter making equipment shown in FIG. 4, the starter making equipment 100 includes: a starter material feeding device 110, a starter pressing device and a caky starter discharge device 120, wherein the starter material feeding device 110 is arranged to fill the die box 161 with the starter material from the starter material supply mechanism 200; the starter pressing device is arranged to repeatedly stamp the starter material in the die box 161 at the multiple positions in a hydraulic driving manner and perform demolding; and the caky starter discharge device 120 is arranged to convey the demolded caky starter outside the starter making equipment 100.
Specifically, the starter pressing device mainly comprises the following parts:
a turntable movement and positioning unit 180, a starter pressing components 140 and a demolding component 190, wherein the die box 161 exists in the starter pressing device in form of a space formed between the turntable 160 and the turntable base 170, that is, multiple through holes may be formed in a surface of the turntable 160, the turntable base 170 closely attached to a lower portion of the turntable 160 may be arranged in a closed and non-holed form at other positions except a demolding position (for example, a pressing position and a cleaning position), then accommodation spaces which may be filled with the starter material are formed between the through holes in the turntable 160 and the turntable base 170, and the spaces implement filling and stamping of the starter material as the die box 161.
Movement of the die box 161 is correspondingly converted into movement of the turntable 160. While the turntable 160 is relatively great in weight, and for accurately implementing movement of the die box 161 between positions, the turntable 160 is required to be driven by the turntable movement and positioning unit 180 to rotate relative to the turntable base 170, so as to move and position the die box 161 formed between the turntable 160 and the turntable base 170 between a preparation position, the multiple pressing positions, the demolding position and the cleaning position.
The starter pressing components 140 are each arranged at respective pressing position, and are arranged to stamp and form the starter material in the die box 161 at the corresponding pressing position. In other words, the starter material is stamped for many times at each pressing position to form the caky starter which may finally be discharged. The demolding component 190 is arranged at the demolding position, and is arranged to demold the starter material in the die box 161 reaching the demolding position and form the caky starter. At the demolding position, a through hole matched with or larger than the contour of the through hole forming the die box 161 in the turntable 160 may be formed in the turntable base 170, so that the caky starter in the die box 161 reaching the demolding position falls from the through hole in the turntable base 170 under the action of extrusion, and thus is further conveyed outside the starter making equipment 100 by the caky starter discharge device 120.
In FIG. 3 and FIG. 4, there may be multiple starter pressing components140, and at least one starter pressing component 140 may be correspondingly arranged at each pressing position. For conveniently driving the multiple starter pressing components 140, each of the starter pressing components is connected preferably by adopting a starter pressing beam 130, and is driven through a pressing hydraulic cylinder 150 in a unified manner.
Multiple through holes may be circumferentially formed in the turntable 160 to form multiple die boxes 161. Each die box 161 may reach a next position from a current position in a stepper manner along with rotation of the turntable 160, and when multiple die boxes 161 reach different pressing positions respectively, the starter material in each die box 161 may be stamped by virtue of the starter pressing component 140 at each pressing position at the same time. When the die box 161 passes through multiple positions, the starter material in the die box 161 is repeatedly stamped for many times to gradually form the dischargeable caky starter.
From FIG. 3, it can be seen that there may be multiple pressing hydraulic cylinders 150 (for example, two), which are connected through synchronous beams 151 to ensure movement synchrony between the multiple pressing hydraulic cylinders.
When the pressing hydraulic cylinders 150 extend out, the starter pressing beams 130 may be driven to move downwards, so as to further drive each of the starter pressing components to move downwards and execute stamping operations over the starter material. On the contrary, when the pressing hydraulic cylinders 150 retract, the starter pressing beams 130 may be driven to move upwards, so as to further drive each of the starter pressing components to move upwards to an initial position.
The demolding component 190 mainly executes an action of separating the caky starter from the die box, and may adopts the same form as the starter pressing component 140. For example, as shown in FIG. 4, the demolding component 190 may also be connected with the starter pressing component 140 through starter pressing beams 130, and when the starter pressing beams 130 move, the demolding component 190 may be driven to move synchronously with the starter pressing component 140.
That is, when the starter pressing component 140 executes the stamping operations, the demolding component 190 also applies downward pressure to the caky starter to implement separation of the caky starter, so that a hydraulic driving system may be simplified. In another embodiment, the demolding component 190 may also adopt a structural form and movement manner different from the starter pressing component .. 140.
An implementation form of the starter pressing component 140 may refer to FIG. 7, and includes a starter pressing hammerhead 146 and a pressing hammer rod 141, the starter pressing hammerhead 146 is connected with a tail end of the pressing hammer rod 141, the pressing hammer rod 141 is driven by a pressing hydraulic cylinder 150 to drive the starter pressing hammerhead 146 to stamp the starter material in the die box 161, a water storage cavity 147 is formed in the starter pressing hammerhead 146, and multiple water outlets 149 are formed in a surface part, in extrusion contact with the starter material, on the starter pressing hammerhead 146 to make water in the starter pressing hammerhead 146 permeate into the starter material in a starter material stamping process, thereby reducing adhesion of the starter material to the starter pressing hammerhead 146. Preferably, the surface part, in extrusion contact with the starter material, of the starter pressing hammerhead 146 may further be wrapped with a water-absorbing fabric, to implement retention of water in the starter pressing hammerhead 146. On the other hand, the water outlets 149 may form a microporous muffling structure, so that noise may be reduced when the starter pressing hammerhead 146 stamps the starter material.
In order to avoid excessive hardness of the caky starter due to rigid impact of the starter pressing hammerhead 146 on the starter material as much as possible, a pressing hammer buffer element (for example, a spring 145 in FIG. 7) may further be added in the starter pressing component 140. The pressing hammer buffer element is connected with the starter pressing hammerhead 146, and is arranged to buffer the starter pressing hammerhead 146 when the starter pressing hammerhead 146 stamps the starter material. In such buffering process, a starter pressing force may usually be fluctuated. Therefore, a sensor may be added in the starter pressing component 140, and compression of the spring is controlled according to monitoring data of the sensor to further ensure stability and adjustability of the starter pressing force.
The sensor may adopt a pressure sensor 142 shown in FIG. 7, and may also adopt a position sensor and the like.
In FIG. 7, the spring 145 is arranged on an outer side of the pressing hammer rod 141 in a sleeve manner, spring pressing seats 143 are connected to its both ends, the upper spring pressing seat 143 is connected with the pressure sensor 142, and the lower spring pressing seat 143 is connected with the starter pressing hammerhead 146.
A part between the spring pressing seats 143 may be protected by a telescopable shield 144. The surface part, in extrusion contact with the starter material, on the starter pressing hammerhead 146 is preferably a bionic alternate flat plate 148, specifically including a hammerhead pressing plate arranged in middle and auxiliary pressing plates arranged on two sides of the hammerhead pressing plate and alternately pressing down, and these pressing plates may adopt a spatial curved surface form. Such bionic structure may simulate a sole in a manual starter stamping process, and the pressing plates with spatial curved surfaces may greatly improve activity of starter material particles in the vicinity of contact surfaces by stamping, reduce an average granularity in a unit measurement circle and greatly improve a 1 syrup purification effect of the surfaces of the pressing plates.
Compared with an existing fitting manner between the hammerhead and the die box, the disclosure may reduce a clearance when the hammerhead presses the starter material to prevent the starter material from being greatly overflowed when being stamped with the hammerhead and further reduce waste of the starter material, and may also effectively control a weight of the caky starter and further ensure quality of the caky starter in a fermentation process.
The demolding component may be designed with reference to the form of the above starter pressing component, and its surface part in extrusion contact with the starter material preferably adopts a flat plate structure to ensure surface smoothness of the caky starter.

Besides the starter pressing components and the demolding component, the starter material feeding device 110 and the caky starter discharge device 120 are also shown in FIG. 4, and wherein FIG. 6 shows an implementation example of the structure of the starter material feeding device 110. The starter material feeding device 110 may specifically include: a material receiving opening 111, a feed hopper 113 and a movable door plate 115, and the feed hopper 113 is connected with the starter material supply mechanism 200 through the material receiving opening 111, and is arranged to receive the starter material conveyed by the starter material supply mechanism 200 through the material receiving opening 111 and unload the starter material into the die box 161 at the preparation position; and the movable door plate 115 is arranged at an outlet of the feed hopper 113, and may be driven to reciprocally move so as to scrape flat the starter material loaded into the die box 161. In FIG. 6, the feed hopper 113 may be supported by a feed hopper bracket 114, and the material receiving opening 1 1 1 is usually arranged in a position higher than the feed hopper 113, and is connected with an inclined plate 112. The starter material entering the material receiving opening 111 may slip into the feed hopper 113 from the inclined plate 112 under the action of gravity, and the starter material entering the feed hopper 113 fills the die box 161 at the preparation position from an outlet at a lowermost end under the action of the gravity. The movable door plate 115 is arranged at the position of the outlet, and may be driven by a rolling motor to intermittently perform reciprocating linear movement.
FIG. 8 shows an implementation example of the structure of the caky starter discharge device 120. The structure may specifically include: a caky starter conveying rack 124, a conveyor belt component 121, a conveyor belt driving motor 123 and a brush 122, and the caky starter conveying rack 124 is connected with the conveyor belt component 121, and is arranged to support the conveyor belt component 121; the conveyor belt component 121 is connected with the starter pressing device, is driven by the conveyor belt driving motor 123, and is arranged to convey the demolded caky starter outside the starter making equipment 100; and the brush 122 is arranged above the conveyor belt component 121, and may be driven to rotate so as to brush away a residue on a surface of the caky starter conveyed by the conveyor belt component 121 to reduce or eliminate burs on an edge of the caky starter. Power transmission may be implemented between the conveyor belt driving motor 123 and the conveyor belt component 121 in a chain transmission manner. One end of the conveyor belt _ component 121 may be arranged below the through hole corresponding to the demolding position on the turntable base 170, so that the caky starter may smoothly fall onto the conveyor belt component 121 from the through hole in the turntable base 170. The other end of the conveyor belt component 121 may be arranged outside the starter making equipment 100 for a worker to carry or convey to a next processing link.
The starter material feeding device 110 is connected with the starter material supply mechanism 200. FIG. 5 shows a schematic diagram of the principle of an implementation example of the starter material supply mechanism 200. The starter material supply mechanism 200 may specifically include: a charging device 210, a charging motor 211, a distributor 212, a dry powder conveying device, a water supply device, a water and powder mixer 205 and a starter material conveying device;
the charging device 210 is arranged to receive and store the crushed dry material;
the charging motor 211 is connected with the charging device 210, and is arranged to add the dry material in the charging device 210 into the distributor 212; the dry powder conveying device is arranged between the water and powder mixer 205 and the distributor 212, and is arranged to convey the dry material in the distributor 212 to the water and powder mixer 205; the water supply device is connected with the water and powder mixer 205, and is arranged to feed water into the water and powder mixer 205 to be mixed and stirred with the dry powder, so as to form the starter material; and the starter material conveying device is arranged between the water and powder mixer 205 and the starter making equipment 100, and is arranged to convey the starter material to the starter making equipment 100.
A horizontal auger 201 and vertical feeder 202 in FIG. 5 may convey the dry .. material in the distributor 212 as the dry powder conveying device, so that the dry material in the distributor 212 may enter the water and powder mixer 205 more uniformly. A horizontal conveying auger 206 and an inclined conveying auger may convey the starter material formed by stirring of the water and powder mixer 205 as the starter material conveying device, so that the stirred starter material may be fed into the starter material feeding device 110 more uniformly.
A humidity of the starter material has remarkable influence on a subsequent liquor making process, so that a water content measurement unit is preferably added in the starter material supply mechanism 200. The water content measurement unit is connected with the water supply device, and is arranged to measure water content of the mixed and stirred starter material so that the water supply device controls an amount of water conveyed into the water and powder mixer 205 according to the water content of the starter material. Correspondingly, in combination with the water cleaning and recycling system 300 shown in FIG. 9, a stirring water tank 315 and an electric adjusting valve 320 may convey water as the water supply device, and the electric adjusting valve 320 may change the amount of water fed into the water and powder mixer 205 according to the water content measurement unit to stabilize the water content of the starter material within a preset numerical value range.
Compared with an existing starter material stirring system completely adopting a conventional empirical method, i.e., a magnitude of water supply is manually controlled by experience, the disclosure may effectively solve the problem of unstable water-powder ratio of the stirred starter material due to individual differences of workers and further ensure stability of quality of a finished liquor product.
Besides control over the water content, control over a feeding amount may also be implemented by material level height detection during supply of the dry material and the starter material. That is, the starter material supply mechanism 200 further includes a dry material height detection unit and a starter material height detection unit. The dry material height detection unit (for example, a material level sensor 209 arranged in the distributor 212 in FIG. 5) is arranged to measure a height of the dry material in the distributor 212 so that the charging motor 211 and the dry powder conveying device control an amount of the conveyed dry material according to the height of the dry material, and may detect an amount of the dry material in the distributor 212. The starter material height detection unit (for example, a material level sensor arranged in the feed hopper 113) is arranged to measure a height of the starter material prepared to fill the die box 161 so that the starter material conveying device and the water and powder mixer 205 control an amount of the conveyed starter material according to the height of the starter material. In the above dry material height detection unit, the measurement and control device may regulate rotating speeds of multiple parts such as a rotating speed of the charging motor, a rotating speed of each auger, a rotating speed of the vertical feeder and a rotating speed of the water and powder mixer through a material height detection result. When it is detected that the material level is excessively high, the measurement and control device may reduce the rotating speed of the motor in each link, thereby avoiding a risk in overflow of the dry material or the starter material. When the material level is lower than a set value, the rotating speed of the motor in each link may be controlled to be increased, thereby implementing quantitative control over the material (the dry material or the starter material).
Under the above detection and control functions of the measurement and control device, the starter material may be supplied more stably, waste of the starter material in a supply process and the condition that the weight of the caky starter is substandard may be reduced, and multiple aspects such as exhaust performance of the caky starter, distribution of batter and compaction balance may meet production requirements in a fermentation process of the caky starter.
It has been mentioned before that flushing the empty die box 162 usually requires a large amount of water resources to be consumed, and the system for continuous caky starter production in the disclosure implements recycling of water by virtue of the water cleaning and recycling system 300. FIG. 9 is a schematic diagram of the principle of a water cleaning and recycling system in an embodiment of a system for continuous caky starter production according to the disclosure, wherein the water cleaning and recycling system 300 includes: a precipitation water tank 311, a clear water tank 305, a main water tank 319, a stirring water tank 315, a nozzle component 310 and a circulating pump 303; the nozzle component 310 is connected with a flushing water supply unit, is positioned above the precipitation water tank 311, and is arranged to flush the empty die box 162 after the demolding in the starter making equipment 100; the clear water tank 305 is communicated with the precipitation water tank 311, and is arranged to overflow clear water obtained by precipitation in the precipitation water tank 311 to the clear water tank 305;
and the circulating pump 303 is arranged between the clear water tank 305 and the main water tank 318, and is arranged to convey clear water in the clear water tank 305 into the main water tank 318 for recycling.
For enabling the clear water tank 305 to appropriately supplement water into the main water tank 318 in time, a sensing unit capable of detecting a liquid level (for example, a high-liquid-level sensor 304 and low-liquid-level sensor 306 shown in FIG.
9) may preferably be arranged in the clear water tank 305, and the circulating pump 303 may be started and stopped according to a liquid level signal detected by the sensing unit. For example, when the high-liquid-level sensor 304 detects a water level signal, the measurement and control device is notified to start the circulating pump 303, and water in the clear water tank 305 is pumped into the main water tank through the circulating pump 303.
After water cleaning the empty die box flows into the precipitation water tank 311, a clear water portion may be separated from starter material impurities with relatively great weight by precipitation, wherein the clear water portion flows into the clear water tank 305 in an overflow manner, and the clear water of this portion may further be used for another process link after being pumped back into the main water tank 318 through the circulating pump 303, so that waste of the flushing water is effectively reduced. For example, the main water tank 318 may be communicated with the stirring water tank 315, and water stored by it may be supplied into the stirring water tank 315 so that the stirring water tank 315 provides water to be mixed and stirred with the dry powder for the water and powder mixer 205 in the starter material supply mechanism 200. For another example, the main water tank 318 may further be communicated with the caky starter discharge device 120 of the starter making equipment 100, and is arranged to wet the conveyor belt component 121 in the caky starter discharge device 120, so as to reduce adhesion to the caky starter. The main water tank 318 is required to keep a preset amount of water, so that a float ball switch 317 may be arranged in the main water tank 318, and when the float ball switch 317 has no signal, a water supplementing electromagnetic valve 324 is opened, and the flushing water supply unit supplements water to the main water tank through a water supply valve 301 and the water supplementing electromagnetic valve 324.
A solid and liquid separation mechanism may further be arranged in a communicating pipeline between the clear water tank 305 and the precipitation water tank 311, the mechanism may be arranged to perform solid and liquid separation on clear water overflowed into the clear water tank 305, and a valve for recycling a solid residue is further arranged at a bottom of the solid and liquid separation mechanism, and the valve may be regularly opened by a user to receive the solid residue after solid-liquid separation.
In FIG. 9, the water cleaning and recycling system may further include a hammerhead water storage tank 322, and the hammerhead water storage tank 322 is communicated with the flushing water supply unit and the water storage cavity 147 in the starter pressing hammerhead 146 in the starter making equipment 100 respectively, and is arranged to supply water to the surface part, in extrusion contact with the starter material, of the starter pressing hammerhead 146.
Considering that there may be deposited a certain amount of dirt in the clear water tank 305, the precipitation water tank 311, the main water tank 318, the stirring water tank 315 and the like, blowdown valves may be arranged on all of these water tanks, and the blowdown valves may be opened to discharge the dirt deposited in the water tanks. For example, a clear water tank blowdown valve 307 is arranged at a bottom of the clear water tank 305, a stirring water tank blowdown valve 314 is arranged at a bottom of the stirring water tank 315, a precipitation water tank blowdown valve 313 is arranged at a bottom of the precipitation water tank 311, and a main water tank blowdown valve 316 is arranged at a bottom of the main water tank 318, wherein blowdown is required to be performed for many times on the precipitation water tank 311 in a production process, so that a clear water electric ball valve 308 and the precipitation water tank blowdown valve 313 may cooperate for regular (for example, every hour) blowdown, and when the clear water electric ball valve 308 and the precipitation water tank blowdown valve 313 are opened, water of the flushing water supply unit may enter the precipitation water tank 311 to discharge the deposited dirt from the precipitation water tank blowdown valve 314. When production is finished, the other blowdown valves may be opened for complete blowdown, and all the valves are recovered into an initial state after blowdown.
