Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically a chemical filtration device for chemical production. Background Technology

[0002] In the chemical manufacturing industry, filtration is a common separation technology. It separates the mixture by forcing a liquid or gas mixture containing solid particles through a porous filter material, thereby capturing the suspended solids. This method effectively separates fluids from insoluble solid particles.

[0003] Extensive searches revealed CN208130643U, which discloses a chemical filter tank for chemical production. The first motor inside the cleaning device rotates, driving the winding wheel and screw to rotate, thereby causing the pull rope to retract and the first baffle to rise. At the same time, the screw rotates, causing the movable rod to move left and right, thereby causing the push plate to move left and right. As the baffle rises to the top of the groove, the push plate simultaneously pushes the solid impurity particles on the filter screen into the collection tank inside the collection device.

[0004] In existing technologies, the equipment mainly filters through the mesh of the filter screen. However, when the chemical raw materials are viscous, the filtration efficiency is low. Therefore, a chemical filtration device for chemical production is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a chemical filtration device for chemical production, which has the advantage of improving the filtration efficiency of the filtration device and solves the problem of low filtration efficiency of the existing device when filtering chemical raw materials.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chemical filtration device for chemical production, comprising a filter chamber, a pressurizing mechanism fixedly installed on one side of the filter chamber, the filter chamber comprising a cylinder, a cover rotatably installed on the top of the cylinder, a filter cylinder movably inserted into the cylinder, and a connecting pipe installed through an opening in the middle of the bottom of the cylinder.

[0007] The connecting pipe adopts an L-shaped structure design. The top of the connecting pipe is embedded in the opening at the bottom of the cylinder, and the lower end face of the connecting pipe has an opening and is connected to a slag discharge valve.

[0008] Preferably, a first support frame is fixedly installed on the lower part of the outer wall of the cylinder, a screw hole is opened at the rear end of the top of the cylinder, and a drain pipe is installed at the rear end of the bottom of the cylinder. The design of the first support frame fixedly installed on the lower part of the outer wall of the cylinder enhances the stability of the filter chamber, ensuring that the filtration device remains stable during high-pressure or large-capacity filtration operations. The screw hole at the rear end of the top of the cylinder facilitates the installation and fixation of the cover, while the drain pipe at the rear end of the bottom optimizes the discharge path of the filtered liquid, making drainage smoother and reducing the residence time of the liquid in the cylinder.

[0009] Preferably, the lower end face of the cover has a groove in the middle, the front end of the cover is rotatably connected to the front end of the top of the cylinder, a handle is fixedly installed on the upper end face of the cover, and a screw hole is provided at the rear end of the upper end face of the cover with a threaded positioning bolt. In this design, the groove on the lower end face of the cover matches the protrusion on the top of the filter cylinder. This fit not only ensures the stability between the cover and the filter cylinder but also facilitates quick disassembly and installation. The rotatable connection between the front end of the cover and the front end of the top of the cylinder, along with the handle fixedly installed on the upper end face, makes opening and closing the cover more convenient. The screw hole and threaded positioning bolt at the rear end of the upper end face of the cover further enhance the stability of the cover, preventing accidental loosening under high-pressure working conditions.

[0010] Preferably, the bottom end of the positioning bolt passes through a threaded hole on the cover and is threaded into a threaded hole on the top of the cylinder. This dual-fixing mechanism, where the bottom end of the positioning bolt passes through the threaded hole on the cover and is threaded into a threaded hole on the top of the cylinder, greatly improves the sealing and stability of the cover. This design ensures ease of operation while also guaranteeing the reliability of the device under high pressure or vibration environments.

[0011] Preferably, the filter cartridge has a protrusion in the middle of its top, which matches a groove at the bottom of the cover. The bottom of the filter cartridge contacts but is not fixedly connected to the bottom of the inner wall of the cartridge. The drain pipe is connected to and installed on the bottom of the cartridge on the outside of the filter cartridge. This design, where the protrusion at the top of the filter cartridge matches the groove at the bottom of the cover, not only ensures a tight fit between the filter cartridge and the cover but also facilitates quick installation and removal of the filter cartridge. The external installation of the drain pipe optimizes the discharge path of the filtered liquid, improving drainage efficiency.

[0012] Preferably, the pressurizing mechanism includes a booster pump, with an inlet pipe connected to the bottom of the booster pump and a discharge pipe connected to the rear end of the booster pump. A second support frame is fixedly installed at the bottom of the front end of the booster pump. The design of the booster pump, with its inlet pipe at the bottom and discharge pipe at the rear end, ensures smooth entry of the raw material and its pressurized discharge. The second support frame at the bottom of the front end of the booster pump provides additional stability, especially under high-pressure operating environments. This support structure ensures the stable operation of the booster pump, thereby improving the overall efficiency and reliability of the filtration device.

[0013] Preferably, the end of the discharge pipe facing away from the booster pump is connected to the front end of the connecting pipe. This connection between the discharge pipe and the connecting pipe creates an efficient raw material inlet path. This design not only simplifies the device structure but also reduces the complexity of pipe connections and lowers the risk of leakage. This optimized feeding system allows the pressurized raw material to enter the filter chamber more quickly, improving the efficiency of the entire filtration process.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, the pressurization mechanism increases the pressure of the raw material entering the filter chamber, thus pushing more material through the filter medium and improving filtration speed and efficiency. This is particularly important for viscous or high-viscosity chemical raw materials, as they may flow slowly under standard atmospheric pressure, leading to low filtration efficiency. The slag discharge valve design allows solid impurities to be periodically discharged from the filter chamber, preventing residual impurities after the filter cartridge is removed, which could lead to excessive solid accumulation and reduced filtration efficiency. It also prevents contamination of the filtered liquid. This design helps maintain the cleanliness of the filter cartridge, ensuring the continuity and efficiency of the filtration process. Simultaneously, the filter chamber design allows for free disassembly and reassembly of the filter cartridge within the chamber, facilitating cleaning and replacement, helping to maintain filtration efficiency, and reducing efficiency reduction due to aging or damage to the filter medium. The cover design includes grooves and a pull handle, making opening and closing the cover more convenient. This design facilitates quick access to the filter cartridge for cleaning or replacement, thereby reducing filtration efficiency reduction due to improper maintenance. The use of positioning bolts enhances the stability of the cover, preventing accidental loosening under high-pressure operating conditions and ensuring sealing and stability during the filtration process, thus avoiding a decrease in filtration efficiency due to poor sealing. Through these designs, this chemical filtration device effectively improves filtration efficiency and reduces efficiency reduction caused by viscous raw materials or filter media clogging. This device is particularly suitable for processing viscous chemical raw materials or those containing large solid particles, improving production efficiency and product quality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of the present invention is provided: a chemical filtration device for chemical production, including a filter chamber 1, a pressurizing mechanism 2 fixedly installed on one side of the filter chamber 1, the filter chamber 1 including a cylinder 11, a cover 12 rotatably installed on the top of the cylinder 11, a filter cylinder 3 movably inserted inside the cylinder 11, and a connecting pipe 112 connected to an opening in the middle of the bottom of the cylinder 11.

[0024] The connecting pipe 112 adopts an L-shaped structure design. The top of the connecting pipe 112 is embedded in the opening at the bottom of the cylinder 11, and the lower end face of the connecting pipe 112 has an opening and is connected to the slag discharge valve 1121.

[0025] Specifically, the pressurization mechanism 2 increases the pressure of the raw material entering the filter chamber 1, thereby pushing more raw material through the filter medium and improving filtration speed and efficiency. This is particularly important for viscous or high-viscosity chemical raw materials, as they may flow slowly under standard atmospheric pressure, resulting in low filtration efficiency. The design of the slag discharge valve 1121 allows solid impurities to be periodically discharged from the filter chamber 1, preventing residual impurities in the filter chamber 1 after the filter cartridge 3 is removed, which would lead to excessive solid accumulation and reduced filtration efficiency. It also prevents contamination of the filtered liquid. This design helps keep the filter cartridge 3 clean, ensuring the continuity and efficiency of the filtration process. Simultaneously, the design of the filter chamber 1 allows the filter cartridge 3 to be freely disassembled and reassembled within the cylinder body 11, making cleaning and replacement of the filter cartridge 3 convenient, helping to maintain filtration efficiency and reducing efficiency reduction due to aging or damage to the filter medium. The cover 12 is designed with grooves and a pull handle 121, making opening and closing the cover 12 more convenient. This design facilitates quick access to the filter cartridge 3 for cleaning or replacement, thereby reducing filtration efficiency reduction due to improper maintenance. The use of positioning bolts 122 enhances the stability of the cover 12, preventing accidental loosening under high-pressure operating conditions, ensuring sealing and stability during the filtration process, and avoiding a decrease in filtration efficiency due to poor sealing. Through these designs, this chemical filtration device effectively improves filtration efficiency and reduces efficiency reduction caused by viscous raw materials or filter media clogging. This device is particularly suitable for processing viscous chemical raw materials or those containing large solid particles, improving production efficiency and product quality.

[0026] Example 2

[0027] To improve the sealing of the filter chamber during filtration, such as Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, a first support frame 111 is fixedly installed on the lower outer wall of the cylinder 11. A screw hole is opened at the rear end of the top of the cylinder 11, and a drain pipe 113 is installed at the rear end of the bottom of the cylinder 11. The design of fixing the first support frame 111 on the lower outer wall of the cylinder 11 enhances the stability of the filter chamber 1, ensuring that the filter device can remain stable during high-pressure or large-capacity filtration operations. The screw hole design at the rear end of the top of the cylinder 11 facilitates the installation and fixation of the cover 12, while the drain pipe 113 at the rear end of the bottom optimizes the discharge path of the filtered liquid, making the drainage smoother and reducing the residence time of the liquid in the cylinder 11.

[0028] Furthermore, a groove is formed in the middle of the lower end face of the cover 12. The front end of the cover 12 is rotatably connected to the front end of the top of the cylinder 11. A handle 121 is fixedly installed on the upper end face of the cover 12, and a screw hole is formed at the rear end of the upper end face of the cover 12, with a positioning bolt 122 threadedly installed. In this design, the groove on the lower end face of the cover 12 matches the protrusion on the top of the filter cylinder 3. This fit not only ensures the stability between the cover 12 and the filter cylinder 3, but also facilitates quick disassembly and installation. The rotatable connection between the front end of the cover 12 and the front end of the top of the cylinder 11, as well as the handle 121 fixedly installed on the upper end face, make opening and closing the cover 12 more convenient. The screw hole and the threaded positioning bolt 122 at the rear end of the upper end face of the cover 12 further enhance the stability of the cover 12 and prevent accidental loosening under high-pressure working conditions.

[0029] Furthermore, the bottom end of the positioning bolt 122 passes through the threaded hole on the cover 12 and is threaded into the threaded hole at the top of the cylinder 11. This dual-fixing mechanism, where the bottom end of the positioning bolt 122 passes through the threaded hole on the cover 12 and is threaded into the threaded hole at the top of the cylinder 11, greatly improves the sealing and stability of the cover 12. This design ensures ease of operation while also guaranteeing the reliability of the device under high pressure or vibration environments.

[0030] Furthermore, the top center of the filter cartridge 3 has a protrusion that matches the groove at the bottom of the cover 12. The bottom of the filter cartridge 3 contacts but is not fixedly connected to the bottom of the inner wall of the cartridge 11. The drain pipe 113 is connected to the bottom of the cartridge 11 on the outside of the filter cartridge 3. The matching of the protrusion at the top of the filter cartridge 3 with the groove at the bottom of the cover 12 not only ensures a tight fit between the filter cartridge 3 and the cover 12 but also facilitates quick installation and removal of the filter cartridge 3. The external installation of the drain pipe 113 optimizes the discharge path of the filtered liquid and improves the drainage efficiency.

[0031] Example 3

[0032] To improve the efficiency of the raw material passing through the filter holes on the filter cartridge during filtration, such as Figure 3 and Figure 4 As shown, in this embodiment, the pressurizing mechanism 2 includes a pressurizing pump 21. A feed pipe 23 is connected to the bottom of the pressurizing pump 21, and a discharge pipe 22 is connected to the rear end of the pressurizing pump 21. A second support frame 211 is fixedly installed at the bottom front end of the pressurizing pump 21. The design of the pressurizing mechanism 2, including the pressurizing pump 21, with its bottom feed pipe 23 and rear discharge pipe 22, ensures the smooth entry of raw materials and their pressurized discharge. The second support frame 211 at the bottom front end of the pressurizing pump 21 provides additional stability, especially under high-pressure operating conditions. This support structure ensures the stable operation of the pressurizing pump 21, thereby improving the overall efficiency and reliability of the filtration device.

[0033] Furthermore, the end of the discharge pipe 22 facing away from the booster pump 21 is connected to the front end of the connecting pipe 112. This connection between the discharge pipe 22 and the connecting pipe 112 creates an efficient raw material inlet path. This design not only simplifies the device structure but also reduces the complexity of pipe connections and lowers the risk of leakage. This optimized feeding system allows the pressurized raw material to enter the filter chamber 1 more quickly, improving the efficiency of the entire filtration process.

[0034] In use, the filter cartridge 3 is inserted into the cylinder 11, ensuring that the protrusion at the top of the filter cartridge 3 matches the groove at the bottom of the cover 12, and that the bottom of the filter cartridge 3 contacts the bottom of the inner wall of the cylinder 11, but is not fixedly connected, so that the filter cartridge 3 can be freely installed and removed from the cylinder 11. The cover 12 is rotatably connected to the front end of the top of the cylinder 11, and the cover 12 is positioned and installed on the top of the cylinder 11 by the positioning bolt 122. The booster pump 21 is correctly connected to the feed pipe 23 and the discharge pipe 22, ensuring that the second support frame 211 of the booster pump 21 is fixed in the appropriate position. When filtering, the booster pump 21 is started. The pressure of the raw material entering the filter chamber 1 is increased, and the raw material is sent into the filter chamber 1 through the feed pipe 23 by the operation of the booster pump 21. The liquid mixture containing solid particles passes through the filter cylinder 3 under the pressure. The solid particles are captured by the filter cylinder 3, while the clean fluid enters the cylinder body 11 through the filter cylinder 3 and is discharged through the drain pipe 113. When a certain amount of solid impurities accumulate on the filter cylinder 3, the cover 12 is opened and the booster mechanism 2 is turned off. Then the filter cylinder 3 is pulled out and the slag discharge valve 1121 is opened to clean the inside of the cylinder body 11 and discharge the solid impurities through the slag discharge valve 1121.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
