Description

Technical Field

[0001] This utility model relates to the field of chamber filter press technology, specifically an automatic unloading chamber filter press. Background Technology

[0002] A chamber filter press is a common solid-liquid separation device. It is often used to dewater sludge from urban sewage and industrial wastewater, reducing the water content of the sludge and facilitating its subsequent transportation and disposal.

[0003] In current chamber filter presses, if the filter cake does not automatically detach after the filter plates separate, the user still needs to manually peel it off and unload it. In addition, residue will adhere to the filter plates and filter cloth, which needs to be manually cleaned so as not to interfere with the next filtration operation. To address this, we propose a new type of automatic unloading chamber filter press. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic unloading chamber filter press to solve the problems of difficulty in automatic unloading and automatic cleaning mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic unloading chamber filter press, comprising a chamber, a PLC controller installed on the outer wall of the chamber, filter plates uniformly slidably connected inside the chamber, filter cloths provided on the filter plates, and telescopic connecting rods uniformly and movably connected between adjacent filter plates, a telescopic cylinder uniformly fixed at one end of the chamber, the output end of the telescopic cylinder connected to a push plate matching the filter plate, a feeding main pipe slidably connected to the filter plate, and drive slide rails fixed at both ends of the top of the chamber, on which self-locking motors are sequentially installed. The machine includes a ball screw and a nut seat. A lifting drive plate is fixed between adjacent nut seats. An air compressor is installed on the lifting drive plate. The output end of the air compressor is connected to a horizontal air guide pipe. A vertical discharge pipe is evenly fixed at the bottom of the horizontal air guide pipe. A nozzle matching the filter plate is installed at the bottom of the vertical discharge pipe. Both ends of the nozzle are evenly provided with spray ports. A discharge base matching the filter plate is installed at the bottom of the machine chamber. A flip base plate is movably connected to both ends of the discharge base. A hydraulic telescopic cylinder is movably connected between both sides of the flip base plate and the discharge base.

[0006] As a further technical solution of this utility model, two feeding main pipes are provided, and adjacent feeding main pipes are respectively arranged on both sides inside the machine compartment.

[0007] As a further technical solution of this utility model, the feeding main pipe is provided with a discharge port evenly arranged on the side near the filter plate.

[0008] As a further technical solution of this utility model, a sludge pump connected to the main feeding pipe is installed at one end of the machine compartment.

[0009] As a further technical solution of this utility model, the self-locking motor is installed on the top of the drive slide rail, the ball screw is connected to the output end of the self-locking motor, and the nut seat is threadedly connected to the ball screw.

[0010] As a further technical solution of this utility model, a bearing is provided between the inner wall of the ball screw and the drive slide rail, and the ball screw and the drive slide rail form a sliding connection.

[0011] As a further technical solution of this utility model, the vertical unloading pipes are arranged at equal intervals on the horizontal air guide pipes, and a flow control valve is installed at the top of the vertical unloading pipes.

[0012] As a further technical solution of this utility model, a water tank is provided on the flipping substrate, and a Teflon non-stick layer is provided on the filter plate, filter cloth and unloading base.

[0013] Compared with the prior art, the beneficial effects of this utility model are: By installing self-locking motors, the device optimizes its structure. On one hand, the self-locking motors on two symmetrically distributed drive rails, in conjunction with the transmission action of ball screws and nut seats, drive the nut seats and the fixed lifting drive plates to move automatically up and down. After completing one filter press operation, solid particles are trapped to form a filter cake, and the filter plates separate. At this time, the lifting drive plate and the horizontal air guide pipe move downwards, causing the vertical discharge pipes, evenly spaced at the bottom of the horizontal air guide pipe, to extend downwards into the cavity formed by the two separated filter plates. Simultaneously, the air compressor starts, and with the flow control valve's flow regulation effect, it can... The compressed air is driven through the spray ports at both ends of the nozzle at the bottom of the vertical discharge pipe to spray the filter plate onto the outer surface. This facilitates automatic discharge of the filter cake and removes and cleans the residue attached to the filter plate and filter cloth. This gives the device both automatic discharge and residue cleaning functions, improving its functionality. On the other hand, after one filter press is completed, the PLC controller will control the filter plate to automatically separate and start the four sets of hydraulic telescopic cylinders on the discharge base. This will cause the two flip plates inside the discharge base to flip downwards, which will facilitate the discharge of the filter cake material downwards for collection, improving convenience. By installing filter plates, the device optimizes its performance. On one hand, the sludge pump starts automatically, drawing the external sludge to be pressed into the filter press structure composed of filter plates and filter cloth through the main feeding pipe. On the other hand, the PLC controller starts the telescopic cylinder according to the preset program, driving the push plate at its output end to slide left and right on the machine chamber. Then, the push plate pushes the filter plates to stack and close or separate. With the limiting effect of the telescopic connecting rod that moves evenly between adjacent filter plates, the position of the filter plates during unloading can be positioned, facilitating subsequent automatic unloading operations. In the closed state, two adjacent filter plates form a filter chamber when pressed together, realizing the sludge pressing and filtration, which facilitates continuous automatic feeding, pressing, and unloading functions.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] Please see Figure 1-5An embodiment of this utility model is provided: an automatic unloading chamber filter press, including a chamber 1, a PLC controller 7 installed on the outer wall of the chamber 1, filter plates 23 are uniformly slidably connected inside the chamber 1, filter cloth 10 is provided on the filter plates 23, and telescopic connecting rods 22 are uniformly movably connected between adjacent filter plates 23. Telescopic cylinders 8 are evenly fixed at one end of the machine chamber 1. The output end of the telescopic cylinders 8 is connected to a push plate 24 that matches the filter plate 23. A feeding pipe 21 is slidably connected to the filter plate 23. Specifically, such as Figure 1 As shown, the PLC controller 7 controls the telescopic cylinder 8 to start according to the preset program, which drives the push plate 24 at its output end to slide left and right on the machine box 1. Then, the push plate 24 pushes the filter plates 23 to stack and close or separate. With the limiting effect of the telescopic connecting rod 22 that is evenly connected between the adjacent filter plates 23, the position of the filter plates 23 when unloading can be positioned, which facilitates the subsequent automatic unloading operation. In the closed state, the two adjacent filter plates 23 form a filter chamber when pressed, which realizes the pressure filtration treatment of sludge. Both ends of the top of the machine compartment 1 are fixed with drive slide rails 6. A self-locking motor 13, a ball screw 11 and a nut seat 12 are installed on the drive slide rails 6 in sequence. A lifting drive plate 5 is fixed between adjacent nut seats 12. An air compressor 4 is installed on the lifting drive plate 5. The output end of the air compressor 4 is connected to a horizontal air guide pipe 2. A vertical discharge pipe 3 is evenly fixed at the bottom of the horizontal air guide pipe 2. A nozzle 15 matching the filter plate 23 is set at the bottom of the vertical discharge pipe 3. Both ends of the nozzle 15 are evenly set with spray ports 16. The self-locking motor 13 is mounted on the top of the drive slide rail 6, the ball screw 11 is connected to the output end of the self-locking motor 13, and the nut seat 12 is threaded onto the ball screw 11. A bearing is provided between the ball screw 11 and the inner wall of the drive slide rail 6, and a sliding connection is formed between the ball screw 11 and the drive slide rail 6. The vertical unloading pipe 3 is arranged at equal intervals on the horizontal air guide pipe 2, and a flow control valve 14 is installed at the top of the vertical unloading pipe 3. Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, the self-locking motors 13 on the two symmetrically distributed drive slide rails 6 are started. With the transmission action of the ball screw 11 and the nut seat 12, the nut seat 12 and the lifting drive plate 5 fixed on it can move automatically up and down. After completing one filter press operation, the solid particles are intercepted to form a filter cake and the filter plates 23 are separated. At this time, the lifting drive plate 5 and the horizontal air guide pipe 2 move downward, so that the vertical discharge pipe 3 arranged at equal intervals at the bottom of the horizontal air guide pipe 2 will extend downward into the cavity formed by the two separated filter plates 23. At the same time, the air compressor 4 is started. With the flow control effect of the flow control valve 14, the compressed air can be driven through the spray ports 16 at both ends of the nozzle 15 at the bottom of the vertical discharge pipe 3 to spray the filter plate 23 onto the outer surface. This facilitates the automatic discharge of the filter cake and the removal and cleaning of the residue attached to the filter plate 23 and filter cloth 10. This makes the device have the functions of automatic discharge and residue cleaning, thus improving its functionality. The bottom of the machine chamber 1 is equipped with a discharge base 9 that matches the filter plate 23. Both ends of the discharge base 9 are movably connected to a flip plate 19. Both sides of the flip plate 19 are movably connected to the discharge base 9 with a hydraulic telescopic cylinder 17. There are two feeding main pipes 21, and adjacent feeding main pipes 21 are respectively located on both sides inside the machine compartment 1; The feeding main pipe 21 has discharge ports evenly arranged on the side near the filter plate 23; A sludge pump 20 connected to the main feed pipe 21 is installed at one end of the machine compartment 1; A water tank 18 is provided on the flip-up substrate 19, and a Teflon non-stick layer is provided on the filter plate 23, filter cloth 10 and unloading base 9. Specifically, such as Figure 4 As shown, after completing one filter press process, the PLC controller 7 will control the filter plate 23 to automatically separate and move, and control the four sets of hydraulic telescopic cylinders 17 on the unloading base 9 to start, driving the two flipping base plates 19 connected inside the unloading base 9 to flip downward, which facilitates the unloaded filter cake material to be discharged downward to the device for collection.

[0018] Working Principle: When in use, with an external power supply, the PLC controller 7 first starts the sludge pump 20 according to a preset program. This automatically draws the external sludge to be pressed into the filter press structure consisting of filter plates 23, filter cloth 10, etc., through the feeding main pipe 21. Next, the telescopic cylinder 8 starts, driving the push plate 24 at its output end to slide left and right on the machine chamber 1. Then, the push plate 24 pushes the filter plates 23 to stack and separate. Combined with the limiting action of the telescopic connecting rod 22, which is evenly movable between adjacent filter plates 23, the position of the filter plates 23 during unloading can be positioned, facilitating subsequent automatic unloading operations. In the closed state, two adjacent filter plates 23 form a filter chamber when pressed together, achieving sludge pressing. The self-locking motors 13 on the two symmetrically distributed drive slide rails 6 start, and with the transmission action of the ball screw 11 and nut seat 12, they can drive the nut seat 12 and the lifting drive plate 5 fixed on it to move automatically up and down, completing one filtration operation. Solid particles are trapped to form a filter cake, and the filter plates 23 separate. At this time, the lifting drive plate 5 and the horizontal air guide pipe 2 move downward, so that the vertical discharge pipe 3, which is equally spaced at the bottom of the horizontal air guide pipe 2, extends downward into the cavity formed by the two separated filter plates 23. At the same time, the air compressor 4 starts, and with the flow control valve 14, it can drive the compressed air through the spray ports 16 at both ends of the nozzle 15 at the bottom of the vertical discharge pipe 3 to spray the filter plate 23 onto the outer surface. This facilitates the automatic discharge of the filter cake and the removal and cleaning of the residue attached to the filter plates 23 and filter cloth 10. This makes the device have the functions of automatic discharge and residue cleaning, improving its functionality. Finally, after completing one filter press process, the PLC controller 7 controls the filter plates 23 to automatically separate and moves, and controls the four sets of hydraulic telescopic cylinders 17 on the discharge base 9 to start, causing the two flip base plates 19 connected inside the discharge base 9 to flip downward. This facilitates the discharge of the unloaded filter cake material downward into the device for collection.
