Description

Technical Field

[0001] This utility model relates to the field of diaphragm filter press technology, specifically to a combined pressing water tank circulating water replenishment device. Background Technology

[0002] The pressing and filtering mechanism is the core component of the diaphragm filter press. It mainly consists of end-sealed corrosion-resistant filter plates, combined filter plates, filter cloth, cloth clamping and distributing device, filter plate support handles, sealing rings at the inlet and outlet of each fluid, a pressing circulating water tank, a pressing water pump, and external pipelines for each fluid. The pressing circulating water tank is a large, vertical, circular circulating water tank for pressing, including a circular tank, an external ladder, and an internal ladder. The cylindrical tank has an inlet, outlet, return outlet, overflow outlet, manhole, and drain outlet. The pressing circulating water tank and the pressing water pump are installed on the ground near the head of the diaphragm filter press. Through pipelines, the pressing water pump connects the pressing circulating water tank and the high-pressure medium chamber of the pressing and filtering mechanism to provide high-pressure water to the pressing and filtering mechanism to expand the diaphragm and press the filter cake for dewatering. The pressing water can be recycled.

[0003] However, existing large vertical circular circulating water tanks for pressing occupy a large area and have high requirements for the installation conditions of the factory, which increases the cost of production enterprises; at the same time, most of the existing circulating water tanks are integrated structures, which are difficult to install and have high maintenance costs. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a combined pressing water tank circulation and replenishment device.

[0005] The technical solution of this utility model is: a combined pressing water tank circulation and replenishment device, including a base, a combined frame disposed on the upper end face of the base, and a circulating water tank disposed inside the combined frame; The combined frame includes a first limiting frame disposed on one side of the upper end face of the base, a second limiting frame slidably engaged with the other side of the upper end face of the base via a first sliding rod, and several docking frames equidistantly distributed between the first limiting frame and the second limiting frame. The circulating water tank includes a water tank end cap that is respectively snapped onto the first limiting frame and the second limiting frame, and several water tank shells that are equidistantly distributed between the two water tank end caps and are respectively movably snapped onto the water tank end caps and the docking frame. One of the water tank end caps is provided with an inlet pipe and a drain pipe at its upper and lower ends, respectively, and the other water tank end cap is provided with a cleaning pipe and a sewage pipe at its upper and lower ends, respectively.

[0006] Furthermore, fastening screws penetrating the second limiting frame are provided at both the upper and lower ends of the first limiting frame near the second limiting frame, and locking nuts are threaded onto both fastening screws; a first docking groove is provided on both sides of each docking frame, and a first sealing ring is sleeved inside each first docking groove. The two water tank end caps are provided with a second mating groove on the side that is close to each other, and a second sealing ring is provided inside the two second mating grooves; the two ends of the water tank shell are respectively engaged with the first mating groove and the second mating groove. Explanation: The connecting frame and the water tank shell located between the first and second limiting frames are tightened using fastening screws. At the same time, the sealing performance of the entire circulating water tank is ensured by the action of the first and second sealing rings.

[0007] Furthermore, each docking frame is provided with guide sleeves at both the upper and lower ends, which are slidably engaged with the two fastening screws one by one, and each guide sleeve is provided with a locking pin that can be movably engaged with the fastening screw at the corresponding position. Note: Using guide sleeves to connect the docking frame and fastening screws helps improve the overall integrity of the combined frame and ensures the reliability of the circulating water tank assembly.

[0008] Furthermore, each of the four corners of the first limiting frame is provided with a reinforcing sleeve, and each of the four corners of the second limiting frame is provided with a reinforcing tie rod that is movably inserted into each of the reinforcing sleeves. Each reinforcing sleeve is provided with a limiting pin that can engage with the reinforcing tie rod at the corresponding position. Explanation: The first and second limiting frames are reinforced by the connection between the reinforcing sleeve and the reinforcing tie rod, which further enhances the stability of the combined frame.

[0009] Furthermore, an inspection ladder is installed on the outer wall of the water tank end cap, corresponding to the location of the cleaning pipe; Note: The installation of the maintenance ladder facilitates the cleaning and maintenance of the inside of the circulating water tank, and also makes it easier to tighten the connection between the circulating water tank and the combined frame.

[0010] Furthermore, each water tank shell has a sealing ring slidably engaged on both sides via a second slide rod, and a third sealing ring is provided on the side of the two sealing rings that are far apart from each other. A push spring that abuts against the sealing ring is sleeved on the second slide rod. Note: Under the action of the push spring, the sealing ring always stays close to the docking frame. The locking action of the third sealing ring with the docking frame achieves a secondary seal between the water tank shell and the docking frame, which helps to improve the reliability of the circulating water tank.

[0011] Furthermore, lifting lugs are provided on both sides of the upper end face of the base; Note: Lifting lugs are provided to facilitate the hoisting and installation of the device, improving the ease of installation.

[0012] The method of using this utility model is as follows: Attach one of the water tank end caps to the first limiting frame. Then, attach the water tank shell to the second mating groove on the water tank end cap, ensuring the end of the water tank shell abuts against the second sealing ring. Next, attach the mating frame to the end of the water tank shell via the first mating groove, ensuring the water tank shell is in contact with the first sealing ring. Repeat this process until the water tank shell is properly mated to the mating frame. Finally, attach the other water tank end cap to the second limiting frame and tighten the locking nut, allowing the second limiting frame to move on the first sliding rod. At this point, the second mating groove on the other water tank end cap engages with the corresponding end of the water tank shell, completing the installation of the entire water tank. In use, connect the inlet pipe and outlet pipe to the pressing and filtering mechanism, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are reflected in the following aspects: First, the structure of this utility model is reasonable. It improves the traditional vertical circular circulating water tank into a horizontal square circulating water tank, which removes the limitation of site area on the installation of the circulating water tank, expands the scope of application of the device, and also improves the site utilization rate when installing the pressing and filtering mechanism, and reduces the equipment construction cost. Secondly, this utility model provides an installation frame for the circulating water tank using a modular frame, ensuring the reliability of the circulating water tank in use; at the same time, the modular circulating water tank can be flexibly assembled according to the water demand of the equipment, improving the ease of use of the device. Third, this utility model uses fastening screws to tightly connect the circulating water tank and the combined frame together, and the sealing performance of the circulating water tank is improved by the cooperation of the first sealing ring and the second sealing ring.
