Description

Technical Field

[0001] This utility model belongs to the field of environmental protection machinery, and in particular relates to a filter press structure. Background Technology

[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to a material, causing the liquid to seep out. It is a commonly used solid-liquid separation device and is still widely used in industries such as chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramics, and environmental protection. A filter press consists of a frame, a pressing mechanism, and a filtration mechanism. The pressing mechanism is composed of a motor reducer, gear set, lead screw, and fixing nut. The filtration mechanism generally consists of filter plates, filter frames, filter cloth, and a pressing diaphragm. The filter plates are covered with filter cloth on both sides. When a pressing diaphragm is required, a set of filter plates consists of a diaphragm plate and side plates.

[0003] Existing patent CN202893017U discloses a large-scale dual-feed filter press with both the thrust plate and the clamping plate having feeding functions. The thrust plate has a feed inlet, and the clamping plate has an auxiliary feed inlet connected to the feed inlet of the filter plate assembly. Advantages: The design of the auxiliary feed inlet on the clamping plate allows for simultaneous feeding from both ends during the filtration stage, resulting in approximately 1.6 times the amount of material entering the filter press per unit time compared to single-end feeding. This significantly improves both the filtration speed and the filtration efficiency per unit time. However, in this patent, the filter plates are connected to the filter cloth, requiring manual operation of each filter plate during sludge unloading and self-cleaning, leading to low work efficiency. Therefore, a more rational filter press structure is needed to better address these existing problems. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a filter press structure that allows the filter cloth to detach from the filter press plate and drives all filter cloths to move synchronously, thereby improving the production efficiency of the filter press.

[0005] In view of this, the present invention provides a filter press structure, characterized in that it includes a frame, on which a filter press assembly is disposed, the filter press assembly including:

[0006] A filter press plate is slidably mounted on a frame, and a feed inlet is provided on the top of the filter press plate;

[0007] A filter cloth is disposed on the side of a filter press plate, and a filter press chamber is formed between the filter press plate and the filter cloth. The filter cloth is used for solid-liquid separation of suspension.

[0008] A slag discharge assembly is mounted on the frame and is used to drive the filter cloth to reciprocate along the height of the frame.

[0009] In this technical solution, when the filter press plate is in a compressed state, the suspension enters the filter press chamber through the feed inlet. Under the filtration action of the filter cloth, the filtered water permeates out of the filter press chamber from the filter cloth, while the filter residue is left on the filter cloth and compacted by the filter press plate. After the filter press plate separates, the movement of multiple sets of filter cloths can be controlled by the residue unloading assembly, so that the filter residue on the filter cloth is automatically unloaded, achieving the purpose of self-cleaning of the filter cloth and improving work efficiency.

[0010] Furthermore, the slag unloading assembly includes:

[0011] A drive chain is disposed on the filter press plate along the height direction of the filter press plate;

[0012] A support rod is fixedly mounted on the drive chain, and a filter cloth is placed between two support rods, forming a complete loop with the drive chain.

[0013] A drive chain assembly is used to drive a drive chain to rotate on a filter press plate.

[0014] Furthermore, the drive chain assembly is disposed on the filter press plate, and the drive chain assembly includes:

[0015] A drive gear is disposed on the top of the filter press plate;

[0016] Driven gear, the driven gear is located at the bottom of the filter press plate, and the driven gear is connected to the driving gear through a drive chain;

[0017] A drive gear assembly is used to drive the drive gear to rotate, thereby driving the material bar to move.

[0018] Furthermore, the drive gear assembly is disposed on the filter press plate, and the drive gear assembly includes:

[0019] A rotating rod is disposed above the filter press plate and passes through the drive gear and is circumferentially fixedly connected to the drive gear;

[0020] A drive rod assembly for driving a rotating rod to rotate.

[0021] Furthermore, the drive rod assembly is mounted on the frame, and the drive rod assembly includes:

[0022] The mounting bracket is fixedly installed on one side of the filter press plate, and the mounting bracket is U-shaped;

[0023] An active bevel gear is mounted on a mounting bracket, and the active bevel gear is axially fixedly connected to the mounting bracket.

[0024] The driven bevel gear is rotatably mounted on the mounting bracket. The driven bevel gear is perpendicular to and meshes with the driving bevel gear. The driven bevel gear is circumferentially fixedly connected to the rotating rod.

[0025] The driven component is used to drive the driving bevel gear to rotate the rotating rod.

[0026] Furthermore, the driven component is mounted on the frame, and the driven component includes:

[0027] Driven drive rod, the driven drive rod is located above the filter press plate, and the driven drive rod is circumferentially fixedly connected to the driving bevel gear;

[0028] A drive assembly for driving a driven rod to rotate a driving bevel gear.

[0029] Furthermore, mounting platforms are provided on both sides of the frame, and the drive assembly is mounted on the mounting platforms. The drive assembly includes:

[0030] The motor is fixedly mounted on the mounting platform;

[0031] A drive wheel is mounted on a motor, and one end of the drive wheel is connected to the output end of the motor via a bearing housing;

[0032] A rotating block is fixedly mounted on both sides of the mounting platform. A right-angle transmission coupling is provided inside the rotating block, and the rotating block is axially fixedly connected to the driven rod.

[0033] The main drive rod is rotatably mounted on the mounting platform along the width direction of the frame. The main drive rod is axially fixed in the rotating block. The main drive rod and the driven drive rod are perpendicular to each other. The drive rod and the driven drive rod are connected by a right-angle transmission coupling.

[0034] The driven wheel is mounted on the main drive rod and is connected to the driving wheel via a toothed chain. The driven wheel is circumferentially fixed to the main drive rod.

[0035] In this technical solution, the motor operates, driving the main drive rod to rotate via the drive wheel and the driven wheel. The main drive rod drives the driven drive rod to rotate, and the drive bevel gear on the driven drive rod rotates, thereby driving the rotating rod to rotate. The rotating rod drives the drive gear to rotate, driving the chain to rotate, allowing the filter cloth to move up and down. This allows the filter residue on the filter cloth to be unloaded during the movement of the filter cloth, achieving self-cleaning of the filter cloth.

[0036] Furthermore, a connecting frame is provided between the mounting platform and the filter press plate, and a feed inlet is provided above the filter press plate. The feed inlets of multiple sets of filter press plates after being pressed together form a feed pipe. A cleaning mechanism is provided on the frame. The cleaning mechanism is used to introduce clean water to clean the feed pipe of the filter press. The direction of the clean water introduced into the feed pipe by the cleaning mechanism is opposite to the direction of the suspension in the feed pipe.

[0037] In this technical solution, the suspension enters the feed pipe from one end, leaving residues in the feed pipe that can clog it. The cleaning mechanism's clean water enters from the other end of the feed pipe, flowing in from the opposite direction to better clean the residues in the feed pipe, thus facilitating the cleaning of the feed pipe.

[0038] Furthermore, the cleaning mechanism includes:

[0042] In this technical solution, clean water enters the first through hole through the inlet pipe. Since the filter plates are in a compressed state, the first through holes on multiple filter plates form a sealed cleaning pipe under the connection of double-sided sealing rings. The clean water enters the connecting pipe through the cleaning pipe, and then enters the feed pipe to clean the residue in the feed pipe. The cleaning pipe formed by the first through holes on the filter plates replaces the water pipe connected to the external clean water, making the structure simpler and the operation more convenient.

[0043] Furthermore, the connecting pipe is fixedly equipped with a one-way valve, which is used to control the flow of clean water in only one direction.

[0044] In this technical solution, under the action of the one-way valve, clean water can only flow to the feed pipe in one direction, preventing the suspension in the feed pipe from entering the cleaning pipe and contaminating it.

[0045] The beneficial effects of this utility model are:

[0046] 1. This utility model uses a brakeable motor to drive the entire sludge unloading assembly, enabling the filter cloth to reciprocate and achieve the purpose of unloading sludge and cleaning the filter cloth in the filter press. Multiple filter cloths can move synchronously, which greatly improves the working efficiency of the filter press and makes the operation of the filter press more intelligent.

[0047] 2. The cleaning mechanism of this utility model is provided by setting a connecting pipe on the filter press, so that the cleaning pipe formed by the first through hole on the filter plate is connected to the feed pipe of the filter press. Water is then introduced into the feed pipe of the filter press through the water inlet pipe and the cleaning pipe to achieve the purpose of cleaning the feed pipe of the filter press. The one-way valve set on the connecting pipe allows the cleaning water in the cleaning pipe to enter the feed pipe of the filter press, while preventing the sludge in the feed pipe of the filter press from entering the cleaning pipe and causing pollution.
