Description

New one-way cheese dyeing machine

The present invention relates to a dyeing and finishing machine, and more particularly to a cheese dyeing machine.

In the dyeing and finishing machinery industry, there is a prior art dyeing machine for cheese yarn. Figure 1 shows the design of such a cheese dyeing machine comprising a cylinder body and a bottom of the cylinder body, wherein the bottom of the cylinder body is connected to a centrifugal pump. The bottom of the cylinder of the dyeing machine is mainly composed of a basic supporting frame such as a rib. The function of the centrifugal pump is to promote the circulation of the dye liquor during the dyeing process. The prior art generally adopts the design of cylinder and pump separation, and the centrifugal pump components are not part of the master cylinder structure.

In the bidirectional cheese dyeing machine of the patent number CN1427111A, the centrifugal pump component includes a transmission device (ie, a motor and a bearing housing, etc.), a transmission shaft, an impeller, and the like. As shown in Figure 1, during maintenance and inspection, the transmission and impeller of the centrifugal pump are separated from the cylinder by removing the docking of the pump cover and the pump casing, but at the same time, the entire fluid operation system is also removed from the original The working position makes it impossible for maintenance personnel to detect when the system is placed in the operating position, and when the removed motor is returned to the original position, positional deviation will occur, which will reduce the efficiency and cause loss. This problem has long plagued production. And users.

At the same time, the dyeing machine master cylinder is separated from the centrifugal pump (1) by a heat exchanger (2). To check the structure inside the centrifugal pump housing, the heat exchanger needs to be removed to view the condition inside the housing from the vacant position, however the heat exchanger With a sealed leak-proof design on both sides of the heat exchanger, forcibly removing the heat exchanger from it will damage the leak-proof structure. Therefore, if the centrifugal pump is to be inspected without damage to the machine, the centrifugal pump and its connected motor must be removed outward to move away from the original position.

At the same time, two-way dyeing is commonly used in the technology of cheese dyeing machines. However, a cheese dyeing machine having a two-way dyeing function widely uses a dye liquid reversing device (see the above patent) for adjusting the flow direction of the dye liquor in the master cylinder. In order to achieve this effect, the dye liquor in the cylinder needs to completely saturate all the cheese yarns, and the water consumption is very high. At the same time, in order to solve the load generated when the fluid pressure in the pump is continuously changed, the main cylinder is pressurized to prevent the pump body from being damaged by cavitation. However, the pressure requirements of the cylinder body are greatly increased, and the design of the cylinder body requires the use of a thicker and harder material. In addition to the high water consumption, such a cheese dyeing machine with a liquid reversing design has to greatly increase the production cost. How to open the fuselage shell without moving the position of the centrifugal pump for maintenance and inspection fluid research, as well as to reduce the working pressure and water consumption of the cylinder body is a long-standing problem in the industry. It is extremely necessary to solve the problems by technical invention. A major breakthrough.

The object of the present invention is to provide a brand-new unidirectional cheese dyeing machine, which realizes the integration of the cylinder body, the centrifugal pump and the heat exchanger, and achieves a low-material, low-water ratio and low-cost dyeing and finishing machine. The design realizes the removal of a part of the centrifugal pump casing of the centrifugal pump casing without moving the centrifugal pump transmission for solid position monitoring.

The invention provides a brand new cheese dyeing machine, wherein the creel (15) has a hollow shape, a bottom has a notch, and a space in the creel (15) communicates with the centrifugal pump outlet (4), and the space extends to the yam (16). ), the yam bamboo is hollow, connected to the space inside the creel, and the surface of the yam has perforation, which allows the dye liquor to overflow from it.

There are fine holes in the veils to allow fluid to escape from the space. The spilled fluid falls into the bottom of the cylinder (5) and flows through the surface of the heat exchanger. The fluid flows through the heat exchange coil (18) and falls into the centrifugal pump inlet (6).

The present invention employs a new centrifugal pump design.

The invention provides a brand new cheese dyeing machine, wherein the casing of the centrifugal pump is vertically divided into two parts by a radial surface of an axial line of the impeller (9) of the centrifugal pump, and is connected to each other by a flange. One half of the housing is integral with the bottom of the cylinder (3) and the other half of the housing (11) is detachable. When half of the housing is removed, the entire drive assembly is clearly visible.

The invention provides a brand new cheese dyeing machine, wherein the centrifugal pump device has a pair of support flanges (12), the support flange is semi-circular, and the profile is inclined Installed diagonally, the impeller shaft (28) and the impeller (9) are placed on the support flange.

The invention provides a brand new cheese dyeing machine, wherein the bottom of the casing (11) of the centrifugal pump is fixed on the platform (10), and the platform (10) is equipped with an axle, placed on the guide rail, and passed through the rotating platform (10) The upper handle separates and engages the housing (11) from the bottom of the cylinder (3) and adjusts the distance therebetween so that it can be accurately aligned with the connecting flange on the master cylinder during reinstallation.

The invention provides a brand new cheese dyeing machine, wherein the centrifugal pump has double suction ports (25a, b), two suction ports are respectively located at two ends of the rotation axis of the impeller (9), and the dye liquor passes through the double suction ports (25a, b). Enter the centrifugal pump.

The invention provides a brand new cheese dyeing machine. The centrifugal pump is provided with an outlet (4) and an inlet (6). The centrifugal pump inlet (6) is a passage for the dye liquor to enter the centrifugal pump, and the centrifugal pump outlet (4) is The dye solution leaves the passage of the centrifugal pump, the centrifugal pump inlet (6) and the centrifugal pump outlet (4) are directed upward, and the centrifugal pump inlet (6) communicates with the return chamber (7) on both sides of the centrifugal pump, and then communicates to the impeller port ( 8). The dye liquor collected from the cylinder body (5) is returned to the centrifugal pump through the return chamber (7), and is rotated back through the impeller (9) to bring the dye liquor back to the cylinder body (5).

The centrifugal pump has been designed to have axial and radial inlets and discharge ports, respectively. In the centrifugal pump body of the present invention, the suction port and the discharge port are designed in the same direction, and the dye liquid inlet of the centrifugal pump inlet (6) and the dye liquid outlet of the centrifugal pump outlet (4) face upward. The dye liquor discharged from the centrifugal pump outlet (4) directly enters the space inside the creel. The dye liquor flowing back from the cylinder body passes through the heat exchange coil and directly enters the centrifugal pump inlet. This design can make the recovered dye liquor more It is quickly looped, except for the unnecessary drainage pipe, which saves space, and the pump body itself is located at the bottom of the master cylinder, which can directly provide the center of gravity support. The pump body with double suction port configuration and the same entrance and exit is a brand new design in the industry.

The invention provides a brand new cheese dyeing machine, wherein the impeller (9) in the centrifugal pump is placed in the impeller chamber (14), located at the center of the centrifugal pump, and the impeller chamber and the return chamber are received by the centrifugal pump outlet (4). The walls are separated, and the opening between the impeller chamber and the return chamber forms a wheel impeller (8) that abuts the suction port of the impeller (9).

The impeller design of the invention is also more efficient than the one-way centrifugal pump of the same diameter, accelerates the circulation of the dye liquor, and the water consumption is less, the frequency of exchange of the yarn spindle and the dye liquor is increased, and a better dyeing effect is obtained. In some processes, if the number of dye exchanges is established, an increase in frequency means that the same process can be completed in a shorter period of time. The shortening of the process time makes the energy consumption of the whole machine relatively reduced, achieving the purpose of energy saving.

It is also an object of the invention to reduce the overall production cost of a cheese dyeing machine. The present invention abandons the original two-way dyeing technique and uses one-way dyeing. There are numerous tiny holes in the winding of the cheese yarn, so that the dye liquid penetrates into the yarn through the pores when it is pumped from the centrifugal pump to the center of the winding. The way in which the dye liquor is oozing out from the center of the winding is called the outflow. The design of the dyeing and finishing machine allows the dye liquor to flow in the opposite direction, that is, the dye liquor penetrates from the package yarn to the center of the winding drum and is then pumped back to the centrifugal pump. This method is called inflow. Regardless of whether it is dyed by means of outflow or inflow, the direction of the dye solution designed by the present invention is single, called unidirectional dyeing.

The advantage of the unidirectional dyeing of the invention is that the design is simple, the dyeing liquid is centrifuged. The pump is pumped into the creel of the cylinder (5) and then split into the windings on each of the yarns and infiltrated into the yarn in an external flow.

Through the use of the "one-way outflow" dyeing process, the water level in the master cylinder does not need to rise to the height of the submerged cheese yarn. The water consumption is only enough to prevent the centrifugal pump from cavitation, which saves most of the volume than the two-way cheese dyeing machine. .

The invention provides a brand new cheese dyeing machine, wherein the centrifugal pump is equipped with an electronic speed control system, which controls the rotation speed of the centrifugal pump with a specific frequency of change, and makes an impulsive flow through a constantly changing dye flow rate. ), to enhance the penetration of the dye solution.

The invention provides a brand new cheese dyeing machine, wherein the bottom of the cylinder body (5) is provided with a heat exchange coil (18), which is composed of a metal hollow annular pipe, is fixed under the creel, and the pipes are connected to each other. Externally connected to water and steam sources.

The bottom of the master cylinder is provided with a heat exchange coil (18) connected to a water source and a steam source other than the dyeing machine. The heat exchange coil (18) is located where the dye liquor is often immersed, usually below the lowest operating water level in the cylinder. When the set temperature in the cylinder is raised, the valve that controls the steam inlet is opened as appropriate to allow steam to enter the heat exchange coil (18). The steam in the coil heats the pipe and makes a temperature difference with the dye liquor flowing through the outer wall of the pipe. At this time, the heat is conducted to the dyeing liquid to achieve the effect of increasing the temperature of the dyeing liquid. Conversely, when the dye solution needs to be cooled, the coil is filled with tap water at room temperature, so that the heat in the dye solution is taken away from it. The flow of water and steam in the coil is controlled by the computer to make a relative rate of increase and decrease in temperature.

In the design of the machine, the heat exchanger is placed in the master cylinder instead of the old one. The heat exchanger is installed to fill the space of water, directly reduce the water consumption, and achieve higher heat exchange efficiency. In the case that the water consumption is reduced and the flow rate of the heat exchange medium is constant, a higher temperature rise or a temperature drop can be achieved from the viewpoint of control, and even a part of the cost of using the heat exchange medium can be saved. If the process only requires the same rate of temperature increase, the amount of steam can be relatively deducted, and the amount of water can be greatly reduced.

The invention provides a brand new cheese dyeing machine, wherein the working door (21) of the cylinder body (5) is provided with a sealed leakage device.

In the process of dyeing, there is a step of washing the cheese yarn with hot water. However, it is a waste of time to inject fresh water into the master cylinder and then heat it. Part of the cheese dyeing opportunity is additionally equipped with a spare cylinder next to the master cylinder, the capacity is equivalent to the amount of water after the master cylinder is filled with dye liquor. The advantage of installing the preparation cylinder is that the clean water is pre-injected into the preparation cylinder for heating, and the package yarn is directly injected into the master cylinder when it needs to be cleaned, saving time.

The invention provides a brand new cheese dyeing machine, wherein the body is provided with a pressurized hole (24) for connecting a source of compressed air.

In the dyeing process, in order to bring the dye liquor in the machine to a temperature above its boiling point, compressed air is injected into the fuselage to increase the pressure in the cylinder. In the case of a sealed operation, an additional pressure causes the temperature of the liquid to rise. When the set temperature drops, the pressure relief valve on the fuselage will open, releasing the pressure inside the cylinder, so that the environment inside the dyeing machine returns to normal atmospheric pressure, providing sufficient conditions for the dye solution to further cool down.

The invention provides a brand new cheese dyeing machine, wherein the cylinder body (5) is connected with a filling system, and the injection system comprises a main pump loop In the throat, the dye liquor can be pumped from the master cylinder to the injection drum or the dyed pigment can be drawn from the injection tank into the dye liquor loop of the master cylinder. The injection tank will also be connected to the water source and steam source to dilute the chemical in the barrel and lift the dye to the appropriate temperature before being pumped into the master cylinder. The water source can also be used as a cleaning tank to drain the sewage through the drainage system. The injection tank also includes a blender to mix the pigments.

The invention provides a brand new cheese dyeing machine, wherein the dyeing machine is provided with a liquid flow control system for controlling the one-way flow of the dye liquor, and the commutation device is omitted, and the dyeing machine is also provided with a pressurization and pressure discharge system. , injection system and temperature rise and fall system.

The invention adopts one-way dyeing, replaces the existing two-way dyeing, can eliminate the reversing device, and the heat exchange system also replaces the external heat exchanger with the heat exchange coil (18), and the structure of the new dyeing machine is older than the old one. Design saves more space. Because there is no commutation, the pressure differential for the centrifugal pump covers a small range. In the case where the maximum working pressure is reduced, it is advantageous to reduce the material for the cylinder casing.

When the cheese yarn is dyed, the stroke of the outer stream and the inner stream dye liquor are different, and the minimum water consumption will be significantly different. As shown in Fig. 11, when the existing cheese dyeing machine dyes the inner flow, the dye liquid flows from the outer portion of the cheese yarn through the entire cheese yarn, the yarn tube and the yarn bamboo, and then flows back to the heat exchanger through the commutator. The main pump, the water level in the master cylinder must be over-the-top lock, otherwise the negative pressure in the cheese yarn will pump the cheese yarn above the water surface into the air from the surface, resulting in pressure difference and flow instability, affecting the dyeing quality.

As shown in Figure 10, when the flow is out, the dyeing liquid flows through the opposite direction. The dyeing liquid is pumped into the creel and the yam by the main pump through the heat exchanger and the commutator, and then the warp yarn. The inner layer of the tube and the cheese yarn is finally returned to the master cylinder through the entire package yarn. As long as the bottom of the cylinder maintains a certain amount of water, the pressure of the main pump can be kept stable, so as to ensure the pressure difference and the flow rate are stable, and it is not necessary for all the packages to be dyed. Liquid coverage.

Existing dyeing machines need to travel inflow (that is, the dyeing liquid infiltrates from the package yarn), and must first ensure that the package yarn is immersed in the dye liquor during the whole process, otherwise some of the air will be drawn into the yarn and even into the main pump, causing cavitation. The phenomenon of damage to the main pump structure. The minimum bath ratio required to soak all the cheese on an existing dyeing machine is approximately 1:4 to 1:6 (in the dyeing and finishing industry, the bath ratio is used as an indicator to measure the weight of the cheese and water in the machine during the dyeing process) proportion).

The present invention dyes a cheese yarn by means of a one-way outflow. The dyeing liquid enters the inner layer of the cheese yarn through the main pump through the creel and the yarn, and then oozes out, and finally collects back to the main pump to form a one-way loop. As long as the bottom of the cylinder maintains a certain amount of water, the main pump pressure can be maintained and the flow rate is stabilized. It is not necessary to have all the packages in the cylinder not be dyed.

Comparing the two models, the dyeing bath ratio of the novelized cheese dyeing machine of the present invention can be reduced to 1:3. In other words, each unit of cheese can save the same amount of water. A new one-way package yarn dyeing machine with a capacity of one ton can save at least one ton of water compared to the old one. Therefore, the present invention saves at least one ton of water per ton of cheese dyeing compared to the conventional cheese dyeing machine. The annual output of Chinese yarn is up to 25 million tons. If the dyeing machine of the invention is used for dyeing, it can save 25 million tons of water per year, which is equivalent to the storage capacity of two and a half West Lakes. It is amazing, and it has greatly reduced pollution emissions.

Using the product of the invention, the advantages of the six provinces can be achieved: power saving, high application The low frequencies alternate. To save water, just use the right amount of water to make sure the main pump does not take time. The steam is saved, and the bath ratio is reduced. Province auxiliaries, the bath ratio is reduced, the corresponding additives are also reduced. The province's process time, the temperature rise and fall time is accelerated, and the process time is shortened. Compressed air, no need to pressurize the machine in some process situations.

The present invention is further illustrated by the following embodiments: as shown in FIG. 2, the present embodiment provides a brand new cheese dyeing machine, including a master cylinder, a creel, a centrifugal pump, and a heat exchange coil (18). The creel is fixed in the dyeing cylinder, and the yam on the creel is hollow and communicates with the main pump outlet. The heat exchange coil (18) is located at the bottom of the master cylinder, and is connected to a water source and a steam source. The centrifugal pump device is located in the bottom support frame of the dyeing machine.

Figure 2 shows a side view of the bottom of the cylinder of the present embodiment. The centrifugal pump outlet (4) is connected to the outlet of the centrifugal pump in the bottom of the cylinder body so that the dye liquor can be delivered from the centrifugal pump outlet to the cylinder body (5) via the centrifugal pump outlet.

The gap defined between the centrifugal pump inlet (6) and the centrifugal pump outlet is defined as a return conduit that is connected to the return chamber (7) on both sides of the centrifugal pump in the bottom of the cylinder to the impeller port (8). The dye liquor collected from the cylinder body (5) is returned to the centrifugal pump through the chamber, and is rotated back through the impeller (9) to bring the dye liquor back to the cylinder body (5).

The clutch design of the main pump housing can also be combined with existing axles and guide rails to make installation or disassembly easier. In this embodiment, an axle mounting platform (10) is attached to the housing to assemble the machine. By turning the hand on the platform The handle allows the operator to separate the housing (11) from the bottom (3) of the cylinder. The axle and rail design ensures seamless engagement of the housing when it is returned, as shown in Figure 3.

The other half of the centrifugal pump housing also includes the portion of the return chamber, the impeller port, the impeller chamber, and the bearing support. The features necessary for these pump casings are designed to be split into two. Since the cross section of the pump casing overlaps with the shaft center, in order to prevent the transmission device from being detached when the casing is removed, the bottom of the main engine body body includes a pair of support flanges (12) on both sides of the centrifugal pump shaft center. The flange body is also divided into two halves and the other half is on the other side of the housing. Unlike the housing abutment flange (13), the cross-section of the support flange is inclined such that the half flange on one side of the bottom of the cylinder can fully support the entire drive shaft.

Figure 4 further illustrates the dyeing operation within the cylinder (5). A part of the centrifugal pump casing including the inlet and outlet and the surrounding rib material constitute a part of the support of the cylinder body (5), and the other half of the casing is also connected with the main cylinder body by screws and sealing rings, which is different from the conventional design. When the casing (11) is taken out, the entire dye liquid conveying system is not removed at the same time. On the contrary, it can stay in the original position, and the housing is taken out transversely with respect to the axis, so that the shaft and the impeller are not affected. The location on the machine. The motor can be removed from this design, eliminating the need to calibrate with the shaft for reinstallation.

In actual operation, the operator puts the cheese yarn (17) on the yarn bamboo (16) and uses the lifting ring (20) on the creel (15) to lift the entire creel and hoist it into the master cylinder. The creel is hollow with a notch at the bottom. After the creel is placed in the master cylinder, the empty space is connected to the centrifugal pump outlet. There is at least one yam on the creel, which is hollow and connected to the space inside the creel. Sabina There are perforations on the surface to allow the dye solution to escape from it. After the creel is fixed in the master cylinder, the dye liquor will be injected into the water level not higher than the cylinder yarn in the cylinder while ensuring that the main pump will not cavitation. However, the water level is set in the dyeing process and mechanical design. Not limited to this. The working door (21) of the master cylinder has a sealed leak-proof design to prevent the dyeing machine from leaking in the dyeing process.

The dye liquor entering the cylinder body (5) from the outlet of the centrifugal pump is diverted to the yam (16) through the creel (15), and permeates into the cheese yarn (17) through the perforations on the yam bamboo, and the flow direction is as shown by the arrow A. . The dyeing liquid flows out from the cheese yarn and flows back to the bottom of the master cylinder. The bottom of the master cylinder is provided with a heat exchange coil (18), and the heat exchange coil tube (18) is composed of one or more sets of circular metal hollow pipes. The pipes are connected to each other and connected to the water source and the steam source. The pipe is mounted below the creel in the master cylinder and on the main passage through which the dye liquor flows. The heat exchange coil (18) floods the heat exchange coil (18) by injecting steam or cold water to heat or cool the dye liquor flowing through the cylinder (5). It is also possible to add any means to control the flow of water or steam into the pipeline before the water or steam source enters the pipeline to achieve the desired rate of temperature rise or decrease. A discharge passage is connected to the other end of the pipe to drain the condensed water. The creel is provided with a dyeing liquid overflow hole (19) for allowing the dye liquor to pass through the creel. The dye solution is finally led back to the main pump and flows as indicated by arrow B. The dye solution flows through the heat exchange coil (18) and falls into the centrifugal pump inlet (6). The inlet of the centrifugal pump is connected to the return chamber (7) in the centrifugal pump, so that the dye solution flows into the return chamber through the inlet of the centrifugal pump. Finally, to the impeller port (8), after pressing, to the centrifugal pump outlet (4), repeat the entire dyeing liquid loop.

When injecting the dye, the operator pours the dye into the drum (22) And start the injection motor (23) to inject the dye into the dye liquor through the injection throat.

According to this embodiment, the pump casings of the double suction centrifugal pump can be made by means of forging, so that the casing including the end of the inlet and outlet of the centrifugal pump has a flange which is connected with the pipe structure of the bottom pipe of the cylinder body (5). Contains the centrifugal pump outlet (4) and the centrifugal pump inlet (6) as shown in Figure 5. Structurally, the steel material can also be welded to make a two-sided housing. As seen in Figure 5, the outlet wall of the centrifugal pump extends toward the butt flange, dividing the space contained in the inlet of the centrifugal pump into three chambers, left, center, and right, wherein the left and right chambers are in communication within the housing and are defined as the return chamber (7). The middle chamber is defined as the impeller chamber (14), and the two walls separating the three chambers have two semi-circular notches near the butt flange, as shown in FIG. The centrifugal pump casing on the other side also has the semicircular notches on the two sides, so that when the two sides of the casing are closed, the two walls separating the return chamber and the impeller chamber in the centrifugal pump are combined into two circular holes concentric with the transmission shaft. Two circular holes are defined as the inlet (8) of the double suction centrifugal pump.

Figure 6 is a cross-sectional view of the return chamber (7) on one side of the centrifugal pump assembly at both ends. The dye liquor that is returned from the cylinder (5) to the inlet of the centrifugal pump is directed to the inlet of the double suction centrifugal pump, as indicated by the arrows in the figure.

Figure 7 shows the structure after the centrifugal pump elements are connected at both ends, wherein the housing (11) is partially cut away to better show its internal structure. The impeller and its transmission shaft are installed in a complete impeller cavity (14) which is formed by combining the two end casings, wherein the impeller has a suction port (25) on both sides thereof, and is connected concentrically with the circular hole during installation to rotate the impeller The suction port can suck the dye liquor from the return chamber into the impeller through the circular hole, and pressurize the dye liquor by the centrifugal force of the impeller rotation. And sent to the centrifugal pump outlet along the impeller chamber.

Figure 8 is a double suction impeller used in the present invention. The design of the impeller basically adopts the pressurized water type design used by a general centrifugal pump. In this embodiment, a total of five vanes are used, but the number is not limited thereto. Different from the conventional impeller, the suction port of the impeller is located at both ends of the axis, in other words, the sides of the impeller are symmetrical. The dye liquor can enter from both ends of the impeller and is forced by the same vane to create fluid pressure.

Figure 9 is a radial cross-sectional view of a double suction impeller. When the impeller rotates clockwise as shown in the figure, the dye liquor in the impeller is pushed out of the impeller by the guide vanes and centrifugal force, and the flow direction is as indicated by the arrow.
