Description
Technical Field
[0001] This utility model relates to the field of chemical equipment technology, and in particular to a special alloy reaction protection filter resistant to strong corrosion. Background Technology
[0002] Filters are essential equipment in industrial production such as chemical, pharmaceutical, and metallurgical industries. They are used to remove solid particulate impurities from fluid media to protect downstream equipment or ensure product purity.
[0003] In many reaction processes, the fluid medium is highly corrosive. This necessitates that the filter itself, especially the core filter element, be made of special materials (such as special alloys) that can resist strong corrosion to ensure the long-term stable operation of the equipment.
[0004] However, no matter how strong the corrosion resistance of the filter element is, after long-term operation, a large number of impurities will inevitably be trapped on its surface, resulting in increased filtration pressure difference and decreased efficiency. Ultimately, it still needs to be disassembled, cleaned or replaced regularly.
[0005] In existing technologies, filters used in highly corrosive environments typically rely on traditional fasteners such as flanges, bolts, and nuts to connect and secure the filter element to the tank. Under prolonged exposure to fumigation and splashing of highly corrosive media, these exposed or contacting fasteners are highly susceptible to rusting, corrosion, or sticking, making disassembly extremely difficult. Operators often need to spend considerable time, or even resort to force, to open the equipment, significantly reducing maintenance efficiency and increasing downtime and maintenance costs.
[0006] Therefore, this utility model proposes a special alloy reaction protection filter that is resistant to strong corrosion to overcome the shortcomings of the prior art. Utility Model Content
[0007] In view of the problems existing in the special alloy reaction protection filter with strong corrosion resistance, such as easy corrosion and rusting of fasteners during filter element disassembly and maintenance, cumbersome and time-consuming disassembly, and extremely low maintenance efficiency, this utility model aims to provide a special alloy reaction protection filter with strong corrosion resistance and improved structure that can effectively solve the above problems.
[0008] This utility model provides a special alloy reaction protection filter resistant to strong corrosion, comprising: a tank body; a tank cover, the tank cover being sealed to the top of the tank body; a jacketed ball valve, the jacketed ball valve being installed on the tank cover and serving as an inlet for the reactants; an outlet, the outlet being located at the bottom of the tank body; a filter assembly, the filter assembly being housed inside the tank body; and a disassembly assembly.
[0009] The filter assembly includes a fixed support plate, which is fixedly connected to the inner wall of the tank, and a ball groove is provided in the locking block; the filter assembly also includes a mounting base; and a filter element, which abuts against the mounting base.
[0010] The disassembly assembly is disposed between the mounting base and the fixed support plate, and is used to enable quick locking and separation of the mounting base and the fixed support plate.
[0011] The disassembly assembly includes: a locking block, which is fixedly connected to the side of the mounting base; a locking pin, which is vertically slidably connected to the inside of the locking block; a ball bearing body, which is accommodated in the ball bearing groove and located on the outer periphery of the locking pin; and a resistance spring, which is disposed inside the locking block and has one end abutting against the locking pin.
[0012] Furthermore, the locking pin, the ball body, the resistance spring, and the ball groove in the locking block are combined in the following manner: when the locking pin is reset under the elastic force of the resistance spring, its tapered portion pushes the ball body outward, causing the ball body to be inserted into the ball groove in the locking block, thereby locking the mounting base.
[0013] Preferably, the filter assembly further includes a sintered mesh, which is fixedly connected to the bottom of the mounting base. The filter element abuts against the sintered mesh through the mounting base, and the sintered mesh provides support and assists in filtration for the filter element.
[0014] Preferably, in order to achieve stable fixation between the filter element and the mounting base, a locking block is fixedly connected to the bottom outer periphery of the filter element, and a slot that cooperates with the locking block is provided on the mounting base.
[0015] Preferably, the filter assembly further includes a fixing ring, which is fixedly connected to the inner wall of the tank, and a fixing plate is fixedly connected to the top of the fixing ring, thereby enhancing the installation stability of the fixing plate.
[0016] Preferably, the disassembly assembly further includes a limiting block disposed at the bottom of the locking pin, and the resistance spring is located between the limiting block and the inner bottom of the locking block, for limiting and installing the resistance spring.
[0017] Preferably, a magnetic valve for backwashing is provided on the top outer side of the tank to facilitate online cleaning of the filter element without shutting down the machine, thus extending the maintenance cycle.
[0018] Preferably, the bottom outer side of the tank is also connected to a support foot to support the entire filter and ensure that the equipment is placed stably.
[0019] Preferably, the filter element is made of a special alloy material that is resistant to strong corrosion, so as to ensure long service life and filtration performance under strong corrosive fluid conditions.
[0020] This utility model has the following beneficial effects:
[0021] 1. This utility model, by setting up a disassembly assembly consisting of a locking pin, a ball bearing body, a resistance spring, and a locking block, utilizes the sliding of the locking pin to push the ball bearing body into or out of the ball bearing groove on the fixed support plate, thereby achieving rapid locking and separation of the mounting base and the fixed support plate. This solves the problem that existing filter element disassembly and maintenance often uses bolts or flanges, which are cumbersome, time-consuming, and labor-intensive, especially with extremely low maintenance efficiency in corrosive environments. It achieves the beneficial effect of improving the efficiency of filter element installation and maintenance and shortening maintenance downtime.
[0022] 2. This utility model solves the problem that traditional filters are easily corroded and damaged when handling highly corrosive fluids, resulting in short service life and frequent replacement, by using a filter element made of a special alloy material that is resistant to strong corrosion. This achieves the beneficial effects of extending the service life of the equipment, ensuring stable filtration performance, and adapting to harsh working conditions.
[0023] 3. This utility model, by setting a magnetic valve, can perform backwashing operation when the filter element is clogged, which solves the problem of a significant decrease in filtration efficiency or the need to stop the machine for cleaning due to filter element clogging during the filtration process, and achieves the beneficial effects of ensuring the stability of equipment operation and extending the manual maintenance cycle.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0031] Example:
[0032] Please refer to Figures 1 to 4 This utility model provides a special alloy reaction protection filter resistant to strong corrosion, which aims to solve the problems of low installation and maintenance efficiency and complex structure of the corrosion-resistant filter element 1 in the prior art.
[0033] like Figure 1 As shown, the special alloy reaction protection filter resistant to strong corrosion includes a tank body 1, a tank cover 4 sealed to the top of the tank body 1, a jacketed ball valve 7 installed on the tank cover 4 and serving as the inlet for the reactants, an outlet 8 located at the bottom of the tank body 1, a support foot 6 connected to the bottom of the outer side of the tank body 1 to support the tank body 1, and a magnetic valve 5 located on the top outer side of the tank body 1 for backwashing.
[0034] like Figure 1 and Figure 2 As shown, the tank 1 contains a filter assembly 2, which includes a fixed support plate 204, a mounting base 202, and a filter element 201. The fixed support plate 204 is fixedly connected to the inner wall of the tank 1, the mounting base 202 is detachably mounted on the fixed support plate 204, and the filter element 201 abuts against the mounting base 202.
[0035] like Figure 1 , Figure 3 and Figure 4As shown, the filter also includes a disassembly assembly 3, which is disposed between the mounting base 202 and the fixed support plate 204. The disassembly assembly 3 includes a locking block 305, which is fixedly connected to the side of the mounting base 202. A ball groove 303 is provided in the locking block 305. A locking pin 301 is vertically slidably connected to the inside of the locking block 305. The ball body 302 is accommodated in the ball groove 303 and is located on the outer periphery of the locking pin 301. A resistance spring 304 is disposed inside the locking block 305 and one end abuts against the locking pin 301. When the locking pin 301 is reset under the elastic force of the resistance spring 304, its conical part pushes the ball body 302 outward, so that the ball body 302 is inserted into the ball groove 303 of the fixed support plate 204.
[0036] To solve the above-mentioned technical problems, the technical solution of this embodiment lies in the precise cooperation between the disassembly component 3 and the filter component 2. Please refer to the following for details. Figure 2 , Figure 3 and Figure 4 The following is a detailed description of the structure and its related connections:
[0037] In the disassembly assembly 3, a limit block 306 is provided at the bottom of the locking pin 301, and a resistance spring 304 is located between the limit block 306 and the inner bottom of the locking block 305.
[0038] In filter assembly 2, a sintered mesh 203 is fixedly connected to the bottom of mounting base 202, and filter element 201 abuts against the sintered mesh 203 via mounting base 202.
[0039] To ensure a stable connection between the filter element 201 and the mounting base 202, a locking block 205 is fixedly connected to the bottom outer periphery of the filter element 201, and a slot 206 that mates with the locking block 205 is provided on the mounting base 202.
[0040] To ensure stable installation of the fixed support plate 204, a fixed support ring 207 is fixedly connected to the inner wall of the tank body 1, and the fixed support plate 204 is fixedly connected to the top of the fixed support ring 207.
[0041] Based on the above embodiments, the present invention may further include the following preferred technical solutions:
[0042] As a preferred embodiment, a magnetic valve 5 is provided on the top outer side of the tank 1 to enable online cleaning or backwashing;
[0043] As a preferred embodiment, in order to facilitate the installation and stable placement of the equipment, a support foot 6 is also connected to the bottom of the outer side of the tank body 1;
[0044] As a preferred embodiment, to ensure the service life and filtration performance of the equipment under highly corrosive conditions, the filter element 201 is made of a special corrosion-resistant alloy material.
[0045] The working principle of this novel special alloy reaction protection filter resistant to strong corrosion is as follows:
[0046] During the filtration operation, the fluid to be filtered enters the tank 1 through the jacketed ball valve 7 on the tank cover 4. The fluid flows to and passes through the filter element 201. Impurities in the fluid are intercepted on the outside of the filter element 201. The filtered clean fluid passes through the sintered mesh 203 at the bottom of the mounting base 202 and is finally discharged from the outlet 8 at the bottom of the tank 1.
[0047] When the filter element 201 needs to be disassembled and maintained, the operator presses down on the locking pin 301 of the disassembly assembly 3. The locking pin 301 slides down in the locking block 305 and compresses the resistance spring 304. The tapered part of the locking pin 301 moves down to provide radial space for the ball body 302 to retract inward. At this time, the mounting seat 202 is pulled up, and the ball body 302 will disengage from the ball groove 303 on the fixed support plate 204. This allows the mounting seat 202, which is fixedly connected to the locking block 305, to quickly separate from the fixed support plate 204, thereby realizing the quick disassembly of the filter assembly 2 and solving the problem of low installation and maintenance efficiency of the traditional filter element 201.
[0048] When reinstallation is required, place the mounting base 202 back onto the fixed support plate 204, release the locking pin 301, and the elastic force of the resistance spring 304 pushes the locking pin 301 upward to reset. The tapered part of the locking pin 301 moves upward and pushes the ball body 302 outward radially, so that the ball body 302 is re-engaged into the ball groove 303 of the fixed support plate 204, thereby relocking the mounting base 202. This process requires no tools and is easy to operate.
[0049] When handling highly corrosive fluids, the filter element 201, made of a special corrosion-resistant alloy, maintains stable filtration performance. When the filter element 201 becomes clogged, the magnetic valve 5 on the top of the tank 1 can be opened for backwashing. The entire device is stably supported by the support feet 6 on the outside of the tank 1.
[0050] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
