The two ends of the extruding shell 82 are through, and the side wall is provided with a plurality of water extruding through holes 85. The extruding shell 82 is used for containing kitchen swill. The squeeze block 89 is movably mounted in the squeeze housing 82 with an outer edge that abuts an inner wall of the squeeze housing 82. A discharge cap 131 is fitted over one end of the crush can 82. The discharging cover 131 is provided with a circular through groove 60 for extruding and discharging. A telescopic member 130 is provided in the pressing housing 82 and serves to push the pressing block 89. The telescopic member 130 may be a hydraulic cylinder, an electric push rod, an air cylinder, etc., which can provide the extrusion block 89 with a pushing force toward the discharge cap 131. The feed hopper 148 is mounted on the squeeze housing 82 and is used to feed kitchen slops/garbage into the squeeze housing 82. A feed valve 149 is mounted on the bottom end of the feed hopper 148 and is used to open or close the feed hopper 148 and also to adjust the discharge amount from the bottom end of the feed hopper 148.

The humidity conditioning system includes a moisture sensor 63, a locking mechanism, and a conditioning controller, and may further include a discharge hopper 136, a hydraulic sensor 137, and a discharge valve 138.

The moisture sensor 63 is mounted on the discharge cover 131, and its detector is located on the side of the discharge cover 131 near the extrusion block 89 and is used to detect the moisture content of the extrusion discharge located in the extrusion housing 82. Moisture sensor 63 can real-time detection moisture content, and it can show through outside display device, makes the moisture content of extrusion ejection of compact can in time be looked around to relevant personnel. Of course, moisture sensor 63 also can be through wireless transmission module remote transmission to data center, and data center just can master the moisture content of the extrusion ejection of compact in real time like this to adjust humidity.

The locking mechanism includes a locking shell 57, a threaded rod 132, at least one positioning rod 133, a limiting block 134, and an adjusting motor 135, and in this embodiment, may further include a rotating shaft 142, a first gear 143, a second gear 144, and a positioning sleeve 145. One end of the locking case 57 is an open end and is fixed to the discharge cover 131. The locking shell 57 can be connected to the dispensing cap 131, thus forming a new dispensing housing. The flow limiting block 134 is in a circular truncated cone structure, the thin end of the flow limiting block is inserted into the circular through groove 60, and the thick end of the flow limiting block is located in the locking shell 57, so that a section of discharging gap is reserved between the flow limiting block 134 and the discharging cover 131. The threaded rod 132 is coaxially arranged with the circular through groove 60, one end far away from the extrusion block 89 is rotatably installed on the side wall of the locking shell 57, and one end close to the extrusion block 89 is in threaded connection with the flow limiting block 134 and extends into the circular through groove 60. The positioning rod 133 is disposed in parallel with the threaded rod 132, and has one end fixed to the inner wall of the locking case 57 and the other end passing through the flow restricting block 134.

In this embodiment, the outer edge of the thicker end of the flow restriction block 134 has at least one step 139, which can cover the circular through groove 60, on one hand, can prevent the extrusion discharge from extruding, and on the other hand, can also play a role of waterproof sealing. The positioning rod 133 passes through the step 139, and the other end thereof is fixed to the discharge cover 131. An adjustment motor 135 is mounted on lock housing 57 and is used to drive threaded rod 132 in rotation. Because the flow limiting block 134 is of a circular truncated cone structure, the depth of the flow limiting block 134 entering the circular through groove 60 determines the size of the discharge gap, and thus when the adjusting motor 135 drives the threaded rod 132 to rotate, due to the limiting effect of the positioning rod 133 on the flow limiting block 134, the flow limiting block 134 can only move along the axial direction of the threaded rod 132, so that the discharge gap can be adjusted, and the discharge amount can be adjusted.

In order to reduce the influence of extrusion discharging on the electrical device, the locking shell 57 of the present embodiment has a discharging cavity 140 and a mounting cavity 141 which are not communicated. The discharging cavity 140 is arranged on one side of the locking shell 57 close to the circular through groove 60, and the thicker end of the flow limiting block 134 is arranged in the discharging cavity 140. The adjustment motor 135 is installed in the installation cavity 141. The discharging cavity 140 is used for accommodating extrusion discharging, and the mounting cavity 141 is used for mounting other components, so that the extrusion discharging can be prevented from damaging other components. One end of the rotating shaft 142 is connected to one end of the threaded rod 132 located in the discharging chamber 140, and the other end of the rotating shaft 142 is rotatably mounted on the side wall of the locking shell 57. The first gear 143 is sleeved on the rotating shaft 142 and is located in the mounting cavity 141. The second gear 144 is engaged with the first gear 143 and is mounted on the output shaft of the adjustment motor 135. The radius of the first gear 143 is larger than the radius of the second gear 144. The adjusting motor 135 drives the rotating shaft 142 through the meshing transmission action of the first gear 143 and the second gear 144 to drive the threaded rod 132 to rotate, and in the process, as the radius of the first gear 143 is larger than that of the second gear 144, the motor can rotate at a high speed to drive the threaded rod 132 to rotate slowly, so that sufficient torque is provided for the threaded rod 132. The locating sleeve 145 is fixed in the circular through groove 60, and one end of the threaded rod 132 close to the extrusion block 89 is rotatably installed in the locating sleeve 145. Wherein, the outer diameter of the positioning sleeve 145 is smaller than the radius of the thinner end of the flow limiting block 134. The locating sleeve 145 is arranged in the circular through groove 60, so that the locating effect on the threaded rod 132 can be achieved, and the threaded rod 132 is enabled to be more stable in rotation.

The adjusting controller is used for judging whether the water content is greater than a preset humidity. When the water content is greater than the preset dry humidity, the adjusting controller drives the adjusting motor 135 to rotate towards one direction, so that the flow limiting block 134 moves towards the extrusion block 89 to reduce the discharging gap. When the water content is smaller than the preset dry humidity, the adjusting controller drives the adjusting motor 135 to rotate towards the other direction, so that the flow limiting block 134 moves towards the direction far away from the extrusion block 89 to increase the discharging gap. Like this, when the regulation controller judges that the moisture content is greater than predetermineeing dry humidity, promptly this moment the ejection of compact moisture is too big and when needing to reduce the moisture, the regulation controller then can make accommodate motor 135 rotate towards a direction for current limiting block 134 removes in order to reduce ejection of compact clearance towards extrusion block 89, and the discharge capacity can reduce like this, thereby can further increase the extrusion to the kitchen swill of not ejection of compact, makes the moisture content reduce. On the contrary, when the moisture content is less than preset dry humidity, it indicates that the discharged water content is too small and the moisture content needs to be improved, the adjusting controller can enable the adjusting motor 135 to rotate towards the other direction, so that the flow limiting block 134 is far away from the extrusion block 89 and the discharging gap is increased, the extrusion amount of the kitchen swill is reduced, and the moisture content is improved. Like this, the humidity of the extrusion ejection of compact can be close to predetermineeing the humidity all the time to the realization is to the regulation of ejection of compact moisture content, makes the moisture content of the extrusion ejection of compact reach actual required standard, guarantees the suitable living environment of follow-up biodegradable reaction bacterial, improves the speed and the effect of follow-up degradation. Moreover, the discharging amount can be adjusted in real time, so that discharging can be more timely, the fault rate is reduced, and normal operation is guaranteed, so that the discharging efficiency of the extrusion system is improved, and the working time is shortened.

In this embodiment, the adjustment controller is further configured to calculate a difference between the moisture content and the preset dry humidity, look up a corresponding steering and rotation amount in a preset difference-steering-rotation amount comparison table, and finally drive the adjustment motor 135 to rotate according to the steering and stop rotating after rotating the rotation amount. In the difference value-steering-rotation amount comparison table, the difference value corresponds to one steering and one rotation amount. The adjusting controller can calculate the difference value between the water content and the preset dry humidity, then inquire the steering and rotating amount of the adjusting motor in the comparison table, and finally control the adjusting motor 135 according to the search result, so that the flow limiting block 134 can reach a preset position, the dynamic control of the dry humidity of the discharged material is realized, the consistency of the water content of the extruded material is ensured, and the adjusting real-time performance is high.

The discharging funnel 136 is installed in the locking shell 57, and the top end is located below the thicker end of the flow limiting block 134, and the bottom end extends out of the locking shell 57. Discharge funnel 136 can hold the extrusion ejection of compact that falls from circular logical groove 60 and collect for the extrusion ejection of compact can in time be discharged, prevents that excessive extrusion ejection of compact from piling up in locking shell 57.

A hydraulic pressure sensor 137 is mounted in the discharge funnel 136 and is used to detect the pressure of the extrudate in the discharge funnel 136 against the bottom wall of the discharge funnel 136. The hydraulic pressure sensor 137 may be an existing hydraulic pressure sensor, and when installed, the detector is located in the discharging hopper 136, and the liquid in the discharging hopper 136 generates hydraulic pressure to the detector, so that the hydraulic pressure sensor 137 detects the value of the hydraulic pressure.

The discharge valve 138 is installed on the discharge end of the discharge funnel 136 and serves to open or close the discharge end of the discharge funnel 136. The adjustment control is also configured to determine whether the pressure reaches a predetermined downforce. When the pressure reaches the preset lower pressure, the adjustment controller drives the discharge valve 138 to open the discharge end of the discharge hopper 136, otherwise drives the discharge valve 138 to close the discharge end of the discharge hopper 136. Like this, the adjustment controller can be through comparing this pressure with predetermineeing the overdraft, carries out the blowing through ejection of compact valve 138 to the extrusion ejection of compact when pressure reaches predetermineeing the overdraft, otherwise just makes ejection of compact funnel 136 continue to collect the extrusion ejection of compact, guarantees the timely collection of the extrusion ejection of compact on the one hand, and on the other hand also guarantees the extrusion ejection of compact and collects the timely blowing of full back, avoids the extrusion ejection of compact to pile up too much and influence the regulation to ejection of compact moisture content.

So, when the regulation controller judges that the moisture content is greater than predetermineeing dry humidity, promptly this moment ejection of compact moisture is too big and when needing to reduce the moisture, the regulation controller then can make accommodate motor 135 rotate towards a direction for current limiting block 134 removes in order to reduce ejection of compact clearance towards extrusion block 89, and the discharge capacity can reduce like this, thereby can further increase the extrusion to the kitchen swill of not ejection of compact, makes the moisture content reduce. On the contrary, when the moisture content is less than preset dry humidity, it indicates that the discharged water content is too small and the moisture content needs to be improved, the adjusting controller can enable the adjusting motor 135 to rotate towards the other direction, so that the current limiting block 134 is far away from the extrusion block 82 and the discharging gap is increased, the extrusion amount of the kitchen swill is reduced, and the moisture content is improved. Like this, the humidity of the extrusion ejection of compact can be close to predetermineeing the humidity all the time to the realization is to the regulation of ejection of compact moisture content, makes the moisture content of the extrusion ejection of compact reach actual required standard, guarantees the suitable living environment of follow-up biodegradable reaction bacterial, improves the speed and the effect of follow-up degradation.

Example 3

Referring to fig. 3, the present embodiment provides a humidity conditioning system in a swill separation process, which is similar to that of embodiment 1, except that the extrusion system has a different structure. In this embodiment, the extrusion system includes an extrusion frame, an extrusion housing 82, a feed mechanism, and an extrusion apparatus.

The extrusion frame is formed by splicing a plurality of square tubes, and the splicing mode can be welding, clamping, screwing and the like, and can be integrally formed. The bottom end of the extrusion frame can be provided with structures such as pulleys, so that the extrusion frame can move on the ground conveniently. Meanwhile, the bottom of the extrusion frame can be provided with a limiting structure, and the limiting structure can limit the extrusion frame to move on the ground, so that the extrusion frame is stably placed at a position required to be fixed. Certainly, the surface of the extrusion frame can be coated with oil-resistant and corrosion-resistant coating, so that the kitchen swill can be prevented from corroding the square pipe. The material of square pipe can be hard materials such as stainless steel or carbon steel, and its quantity is decided according to the overall structure of extrusion frame, can guarantee holistic fastness as far as possible.

The extrusion housing 82 is mounted on an extrusion frame, and in some embodiments, the extrusion housing 82 may be integrally formed with the extrusion frame. Wherein, set up extrusion chamber 83 and water storage space 84 in the extrusion shell 82, extrusion chamber 83 and water storage space 84 coaxial setting. The water storage space 84 is located outside the squeezing chamber 83 and communicates with the squeezing chamber 83 through a plurality of squeezing through-holes 85 opened in the squeezing housing 82. The water storage space 84 may be shaped in a ring shape in practice, which surrounds the squeezing chamber 83 so that liquid squeezed out of the squeezing chamber 83 can be stored in the water storage space. At least two sliding grooves 86 parallel to the axial direction of the extrusion cavity 83 are formed on the inner wall of the extrusion shell 82 close to the extrusion cavity 83, and one end of the extrusion shell 82 is an open end.

The feed inlet of the feeding mechanism is inserted into the other end of the extrusion shell 82 and is used for conveying kitchen swill into the extrusion cavity 83. In this embodiment, the feeding mechanism includes a feed hopper 101. The feeder hopper 101 is secured to the squeeze frame and squeeze shell 82 with the mouth of the hopper located in the squeeze chamber 83. In other embodiments, the feeding mechanism may convey the kitchen waste into the extruding cavity 83 by other structures, such as a tubular structure like a feeding pipe, and also convey the kitchen waste into the extruding shell 82 by a groove-shaped structure.

The extruding device comprises an extruding motor 87, a stud 88, an extruding block 89, a stirring fan blade 90 and a positioning column 105. An extrusion motor 87 is mounted on the extrusion frame and the output shaft is connected to one end of a stud 88. A stud 88 is positioned in the extrusion chamber 83, the central axis of which may coincide with the central axis of the extrusion chamber 83. The extrusion block 89 is screwed on the stud 88, and the outer wall of the extrusion block is attached to the wall of the extrusion cavity 83. The pressing block 89 is provided with at least two sliding blocks 91, the number of the sliding blocks 91 is at least two, the at least two sliding blocks 91 respectively correspond to the at least two sliding grooves 86, and each sliding block 91 can slide in the corresponding sliding groove 86. Therefore, when the stud 88 rotates, the sliding block 91 can only slide in the sliding groove 86, so that the extruding block 89 integrally moves along the axial direction of the stud 88, and the extruding function of the kitchen swill in the extruding cavity 83 is realized. The number of the stirring blades 90 is at least one group, and each group of the stirring blades 90 is inserted around the other end of the stud 88. Two ends of the positioning column 105 are respectively fixed on the inner wall of the extrusion shell 82, and the other end of the stud 88 is rotatably installed in the positioning column 105, so that the stud 88 is more stable in rotation. The stirring fan blades 90 can stir the kitchen swill when the stud 88 rotates, so that the kitchen swill can be more uniformly distributed in the extrusion cavity 83. Meanwhile, the resistance of the stirring fan blades 90 in the extrusion process is certainly increased, so that the depth of the stirring fan blades 90 in the extrusion cavity 83 needs to be fully considered when the stirring fan blades 90 are installed, the number and the blade surface of the stirring fan blades 90 can be reduced, and the stirring can be smoothly carried out.

In the present embodiment, the stud 88 includes a connecting section 98, a threaded section 99, and a stop section 100.

Each set of stirrer blades 90 is connected to the threaded section 99 by a threaded sleeve 80. The threaded sleeve 80 is in threaded connection with the threaded section 99 and is limited above the limiting section 100. Thus, when the stud 88 rotates, when the resistance of the kitchen swill to the stirring fan blade 90 is relatively small, the stirring fan blade 90 still rotates along with the rotation of the stud 88, and when the resistance is relatively large, the threaded section 99 and the threaded sleeve 80 rotate relatively, and the stirring fan blade 90 stops rotating and moves along with the axial movement of the threaded sleeve 80 along the threaded section 99 to move to a place with relatively small resistance. Like this, stirring fan blade 90 just can realize the stirring function of multizone for the kitchen swill fully distributes in extrusion chamber 83.

This extrusion system that innoxious separation swill was used, its extrusion shell set up extrusion chamber 83 and water storage space, and the water storage space is located the outside in extrusion chamber to communicate through a plurality of crowded water through-holes, the liquid of extruding in the extrusion chamber like this will be stored in entering into the water storage space through crowded water through-hole. The extrusion motor drives the double-screw bolt to rotate through rotating, because threaded connection between double-screw bolt and the extrusion piece, simultaneously because the limiting displacement of slider and spout, the double-screw bolt rotates just so and can only order about the extrusion piece and remove at extrusion chamber central line, and can not produce and rotate to extrude the kitchen swill in the extrusion chamber, make extrusion water flow out and collect in the space of going out water from crowded water through-hole, accomplish the extrusion dehydration process to kitchen swill.

Example 4

Referring to fig. 4 and 5, the present embodiment provides a humidity adjusting system for swill separation process, which is used together with a crushing system. The crushing system can be used as a partial structure of kitchen swill treatment equipment, and can also be independently arranged to be an independent system. Wherein, this crushing system includes support body 31, crushing roller 32, broken motor 33, washes mechanism, statistics mechanism and crushing controller.

The frame body 31 is formed by splicing a plurality of square tubes, and the splicing mode can be welding, clamping, screwing and the like, and can also be integrally formed. The bottom end of the frame body 31 may be provided with a pulley and the like so that the frame body 31 moves on the ground. Meanwhile, the bottom of the frame body 31 can be provided with a limiting structure, and the limiting structure can limit the frame body 31 to move on the ground, so that the frame body 31 is stably placed at a required fixed position. Certainly, the surface of the frame body 31 can be coated with oil-resistant and corrosion-resistant coating, so that the kitchen swill can be prevented from corroding the square pipe. The material of square pipe can be hard materials such as stainless steel or carbon steel, and its quantity is decided according to the overall structure of support body 31, can guarantee holistic fastness as far as possible. In this embodiment, the frame 31 includes a crushing shell 48, and both the upper and lower ends of the crushing shell 48 are open ends. In this case, the humidity control system of embodiment 1 may be directly installed in the frame body 31.

The number of the crushing rollers 32 is at least two, and the crushing rollers 32 are rotatably mounted on the frame body 31. The two crushing rolls 32 are arranged in parallel in the axial direction, and the two ends of the two crushing rolls are aligned and separated by a preset rolling space. Wherein, wet rubbish enters from the same side of two crushing rollers 32, and leaves from the same side of two crushing rollers 32 after rolling through the preset rolling space. In this embodiment, the crushing roller 32 is rotatably mounted in the crushing shell 48, and the roller surface of the crushing roller 32 may be provided with a wear-resistant coating, which ensures a long-term use of the roller surface. In other embodiments, the roll surface of the crushing roller 32 may be provided with a convex structure, which can cut the meal or other solid composition in the kitchen waste, so that the kitchen waste can be sufficiently rolled and decomposed.

A crushing motor 33 is mounted on the frame body 31 and is used to drive the crushing roller 32 to rotate. The crushing motor 33 can be connected with the crushing roller 32 through a gear box, and can provide large torque for the crushing roller 32, so that the two crushing rollers 32 can sufficiently roll kitchen swill. Of course, the crushing motor 33 may also be arranged directly outside the crushing shell 48, with its output shaft inserted into the crushing shell 48 and coaxially connected with one of the crushing rollers 32. The working power of the crushing motor 33 can be selected according to the actual crushing requirements, i.e. when the crushing system is a small crushing device, the crushing motor 33 can be a low-power motor, and when the crushing system is a large crushing device, the crushing motor 33 needs to be replaced by a high-power motor.

The flushing mechanism includes a plurality of spray heads 34, the spray heads 34 being mounted on the frame 31. The spray head 34 is located on the same side of the two crushing rollers 32, and is used to spray washing water onto the roller surfaces of the crushing rollers 32. The washing mechanism can realize the cleaning function of the crushing roller 32, so that the roller surface can be kept clean, dirt generated in the long-term use process of the crushing roller 32 can be prevented from being accumulated, and the rolling efficiency of the crushing system is improved.

The statistical mechanism comprises a first detection component, a second detection component and a calculation module. The detection assembly I is used for detecting the first accumulated amount of the wet garbage entering the preset rolling space within a preset time period. The second detection assembly is used for detecting the second accumulation amount of the wet garbage leaving the preset rolling space in the preset time period. The calculation module is used for calculating the accumulated difference between the first accumulated amount and the second accumulated amount. Wherein the accumulated difference is the difference obtained by subtracting the accumulated amount two from the accumulated amount one. In this embodiment, the first detecting component can measure the garbage entering the rolling space through a device such as a flowmeter, and similarly, the second detecting component can also measure the rolled garbage through a device such as a flowmeter. Since there may be some dust adhering to the roll surface during rolling, the amount of dust remaining in the rolling space can be determined by determining the difference between the two measurements, and the crushing roll 32 can be cleaned using this information.

The crushing controller is configured to determine whether the cumulative difference is greater than a first preset crushing amount and not greater than a second preset crushing amount, and if so, drive the spray head 34 to spray the cleaning water. When the accumulated difference is between the first preset crushing amount and the second preset crushing amount, the situation that part of garbage is adhered to the roller surface at the moment is shown, and the roller surface needs to be cleaned, so that the crushing controller can drive the flushing mechanism to clean the roller surface. The crushing controller is also used for judging whether the cumulant difference is larger than a second preset crushing amount and not larger than a third preset crushing amount, if so, the spray head 34 is driven to spray cleaning water, and the rotating speed of the crushing motor 33 is increased according to the difference value of the cumulant difference and the third preset crushing amount. Wherein the increase in the rotational speed is positively correlated with the difference. When the accumulated difference is between the second preset crushing amount and the third preset crushing amount, the amount of the garbage adhered to the roller surface is very large, and the roller surface is required to be washed and the rolling speed is required to be increased so as to treat the garbage accumulated in the rolling space. The crushing controller is also used for judging whether the accumulated difference is larger than a preset crushing amount three, and if so, driving the crushing motor 33 to stop rotating. When the accumulated difference is larger than the preset crushing amount three, which indicates that the amount of garbage in the grinding space reaches the upper limit, if the crushing motor 33 continues to rotate, the crushing motor 33 and other equipment may be damaged, and thus the crushing controller stops the rotation of the crushing motor 33.

It should be noted here that the material crushed by the crushing system can be conveyed to the extrusion system in embodiment 1 for extrusion, and the humidity adjusting system in this embodiment can adjust the humidity of the extrusion discharge.

A preset rolling space is formed between the two crushing rollers 32 of the crushing system, so that wet garbage separated from kitchen swill can be rolled in the space, larger garbage can be crushed into fine garbage, and the crushing function of the wet garbage is realized. The spray head 34 of the flushing mechanism of the system can spray water to the roller surface for flushing, can flush garbage adhered to the roller surface, and guarantees the cleanliness of the roller surface, so that the crushing efficiency of the crushing roller 32 can be improved. The first detection assembly of the statistical mechanism can detect the feeding amount of the wet garbage in a period of time, the second detection assembly synchronously detects the discharging amount of the wet garbage in the period of time, and finally the calculation module calculates the difference value between the feeding amount and the discharging amount so as to facilitate the judgment of the crushing controller. The crushing controller compares the accumulated difference with each preset range and respectively processes: (1) when the accumulated difference is not greater than the preset crushing amount, it indicates that excessive garbage is not attached to the crushing roller 32 at this time, cleaning may not be performed, and the rotating speed of the crushing motor 33 does not need to be increased, so that waste of washing water and crushing energy is avoided; (2) when the accumulated difference is greater than the first preset crushing amount and not greater than the second preset crushing amount, a certain amount of garbage is attached to the roller surface, the fact that the roller surface needs to be washed is indicated, and the crushing controller controls the washing mechanism to wash; (3) when the accumulated difference is larger than the second preset crushing amount and smaller than the third preset crushing amount, the attached garbage on the roller surface is further increased, so that the crushing controller not only needs to wash the roller surface, but also needs to increase the rotating speed of the crushing motor 33 to accelerate the treatment speed of the wet garbage; (4) when the accumulated difference is greater than the preset crushing amount three, excessive wet garbage exists in the preset rolling space, and serious damage is caused to the crushing motor 33, so that the crushing motor stops working by the crushing controller. So, this broken system not only can improve the treatment effeciency to wet rubbish, improves the broken speed of rubbish, can also improve the utilization ratio to washing resource and energy, can also protect broken motor 33 simultaneously, improves broken motor's life.
