Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically a clamp-type filter with a quick-opening cap structure. Background Technology

[0002] A filter is a device used to separate impurities from fluids. It intercepts pollutants such as solid particles and suspended matter through physical or chemical methods, so that the medium meets purification standards.

[0003] For example, the Chinese authorized patent CN209049099U (A Canister-Shaped Filter) includes a cylinder, a cover, and a bottom. The cover and bottom are sealed to the cylinder via locking devices. The cover has a feed inlet, an air inlet, and an air outlet. The bottom has a discharge outlet connected to a discharge pipe. At least one layer of filter screen is provided inside the cylinder. A blowing plate is detachably fixed inside the bottom. The blowing plate has multiple filtrate holes and air holes evenly distributed. An air inlet is provided on the bottom. The blowing plate is connected to an air pump via the air inlet. This invention ensures that all liquid materials are filtered in a closed environment, preventing material evaporation and loss. Operators do not come into contact with the materials, avoiding harm to the human body, and enabling continuous filtration. Air is blown onto the filter screen through the blowing plate inside the bottom to disperse the filter cake, preventing filter cake accumulation and subsequent cleaning problems.

[0004] However, the existing filter cap is connected to the cylinder body by fasteners. When the cylinder body needs to be cleaned and inspected, tools are required to open the cap, which is time-consuming, labor-intensive and lacks flexibility. Therefore, it does not meet the current needs. To address this, we propose a clamp-type filter with a quick-opening cap structure. Utility Model Content

[0005] The purpose of this utility model is to provide a clamp-type filter with a quick-opening structure, so as to solve the problem mentioned in the background art that the cover of the existing filter is connected to the cylinder body by fasteners, and when the inside of the cylinder needs to be cleaned and inspected, tools are required to open it, which is time-consuming, labor-intensive and lacks flexibility.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamp-type filter with a quick-opening structure, comprising: a cylinder body, a cylinder cover at the upper end of the cylinder body, a pressure gauge on the upper surface of the cylinder cover, a clamp on the outside of the connection between the cylinder body and the cylinder cover, a first valve seat at one end of the clamp, a second valve seat at the other end of the clamp, a stabilizing component at the top of the cylinder cover, and a fixing component on one side of the first valve seat, wherein the first valve seat and the second valve seat are connected by the fixing component.

[0007] Preferably, the fixing component includes a bidirectional threaded rod, one end of which passes through the first valve seat and the second valve seat in sequence, and the bidirectional threads on the outer surface of the bidirectional threaded rod are threadedly connected to the first valve seat and the second valve seat respectively, and a handwheel is provided at the other end of the bidirectional threaded rod.

[0008] Preferably, a support seat is provided at the lower end of the rotating part of the clamp, and the support seat is welded and fixed to the cylinder body, and the clamp is fixed to the support seat by external bolts.

[0009] Preferably, the stabilizing component includes a stabilizing plate, and both ends of one side of the stabilizing plate are provided with stabilizing connection grooves, and one side of the stabilizing connection groove is open. The upper side of one side of the first valve seat and the second valve seat are provided with stabilizing connection posts, and the stabilizing connection posts are inserted into the stabilizing connection grooves along the openings.

[0010] Preferably, the stabilizing component further includes a lower pressure arm, which is located on one side of the stabilizing plate. One end of the lower pressure arm is provided with an adjusting arm, one end of the adjusting arm is provided with a connecting arm, and one end of the connecting arm is provided with a positioning rod. The lower end of the positioning rod is welded and fixed to the cylinder cover. The connection points of the lower pressure arm, adjusting arm, connecting arm, and positioning rod are all rotatably connected by an external rotating shaft.

[0011] Preferably, a rotating frame is provided on the rear surface of the cylinder cover, a positioning frame is provided at one end of the rotating frame, a rotating shaft is provided at the connection between the positioning frame and the rotating frame, and the rotating frame is rotatably connected to the positioning frame through the rotating shaft. A fixing plate is provided on the rear surface of the cylinder, and the fixing plate is fixed to the positioning frame by external bolts.

[0012] Preferably, the lower end of the clamp is provided with a stabilizing plate, and one end of the stabilizing plate is welded and fixed to the cylinder body, and the clamp is L-shaped.

[0013] Preferably, the front surface of the cylinder near the top is provided with a feed inlet, the rear surface of the cylinder near the bottom is provided with a discharge outlet, and the outer surface of the cylinder near the bottom is welded with a support leg.

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

[0015] (1) This utility model sets a clamp on the outside of the connection between the cylinder and the cover. When the cover is closed, the handwheel is turned and the first valve seat and the second valve seat are moved to the middle through the double-threaded rod, thereby tightening the clamp. The position of the lower pressure arm is adjusted by rotating so that the stable connecting column is inserted into the stable connecting groove along the opening. The stable connecting column is limited by the stable plate to prevent the two stable connecting columns from separating, which also prevents the first valve seat and the second valve seat from separating, thus improving the connection stability. When the cover needs to be opened, the separation stable plate is turned first, and then the double-threaded rod is turned in the opposite direction. The first valve seat and the second valve seat will move in the opposite direction to open the cover. At this time, the clamp is loosened and the connection between the cover and the cover loses the squeezing force. The cover can then be turned to open, realizing quick opening and improving flexibility and convenience. This solves the problem that the cover of the existing filter is connected to the cylinder by fasteners. When the cover needs to be opened to clean and repair the inside of the cylinder, tools are needed to open it, which is time-consuming, laborious and lacks flexibility.

[0016] (2) By setting a stabilizing plate at the lower end of the clamp and welding one end of the stabilizing plate to the cylinder, the clamp is supported by the stabilizing plate. At the same time, the stabilizing plate has an L-shaped structure, which limits the clamp and prevents it from falling, thereby improving stability and safety. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 An embodiment of this utility model is provided: a clamp-type filter with a quick-opening cover structure, comprising: a cylinder 1, an inlet 7 provided on the front surface of the cylinder 1 near the top, an outlet 8 provided on the rear surface of the cylinder 1 near the bottom, and a support leg 9 welded to the outer surface of the cylinder 1 near the bottom. The filter is fed through the inlet 7 and discharged from the outlet 8 after filtration.

[0024] A cylinder cover 2 is provided at the upper end of the cylinder body 1. A pressure gauge 3 is provided on the upper surface of the cylinder cover 2. A clamp 6 is provided at the connection between the cylinder body 1 and the cylinder cover 2. A first valve seat 15 is provided at one end of the clamp 6, and a second valve seat 16 is provided at the other end of the clamp 6. A stabilizing component 4 is provided at the top of the cylinder cover 2. A fixing component 5 is provided on one side of the first valve seat 15, and the first valve seat 15 and the second valve seat 16 are connected through the fixing component 5. The fixing component 5 includes a bidirectional threaded rod 24, and one end of the bidirectional threaded rod 24 passes through the first valve seat 15 and the second valve seat 16 in sequence. The bidirectional threads on the outer surface of the bidirectional threaded rod 24 are threadedly connected to the first valve seat 15 and the second valve seat 16 respectively. A handwheel 25 is provided at the other end of the bidirectional threaded rod 24.

[0025] The stabilizing assembly 4 includes a stabilizing plate 22. Stabilizing connecting grooves 23 are provided on both ends of one side of the stabilizing plate 22, and one side surface of the stabilizing connecting grooves 23 is open. Stabilizing connecting posts 17 are provided on the upper surfaces of one side of the first valve seat 15 and the second valve seat 16, and the stabilizing connecting posts 17 are inserted into the stabilizing connecting grooves 23 along the openings. The stabilizing assembly 4 also includes a lowering arm 21, which is located on one side of the stabilizing plate 22. An adjusting arm 20 is provided at one end of the lowering arm 21. One end of the cylinder cover 2 is provided with a connecting arm 18, and the other end of the connecting arm 18 is provided with a positioning rod 19. The lower end of the positioning rod 19 is welded and fixed to the cylinder cover 2. The connection points of the pressing arm 21, adjusting arm 20, connecting arm 18 and positioning rod 19 are all rotatably connected by an external rotating shaft. The rear surface of the cylinder cover 2 is provided with a rotating frame 11, and one end of the rotating frame 11 is provided with a positioning frame 12. A rotating shaft 14 is provided at the connection point between the positioning frame 12 and the rotating frame 11, and the rotating frame 11 is connected to the positioning frame via the rotating shaft 14. 12 Rotary connection, the rear surface of the cylinder 1 is provided with a fixing plate 13, and the fixing plate 13 is fixed to the positioning frame 12 by external bolts. When the cylinder cover 2 is closed, the rotating frame 11 is rotatably connected to the positioning frame 12 through the rotating shaft 14, so that the cylinder cover 2 rotates and contacts the upper surface of the cylinder 1. Then, the handwheel 25 is rotated to drive the bidirectional threaded rod 24 to rotate along the first valve seat 15 and the second valve seat 16. Since the bidirectional threads on the outer surface of the bidirectional threaded rod 24 are threadedly connected to the first valve seat 15 and the second valve seat 16 respectively, the first valve seat 15 and the second valve seat 16 move towards the middle and get closer and closer, thereby tightening the clamp 6 and squeezing and sealing the connection between the cylinder 1 and the cylinder cover 2. Then, the position of the lower pressure arm 21 is rotated and adjusted so that the stabilizing connecting column 17 is inserted into the stabilizing connecting groove 23 along the opening. The stabilizing plate 22 limits the stabilizing connecting column 17 to prevent the two stabilizing connecting columns 17 from separating, which also prevents the first valve seat 15 and the second valve seat 16 from separating, thus improving the connection stability.

[0026] When it is necessary to open the cylinder cover 2, the angles of the adjusting arm 21, adjusting arm 20, connecting arm 18 and positioning rod 19 are rotated to separate the stabilizing plate 22 from the first valve seat 15 and the second valve seat 16. In this way, the two stabilizing connecting columns 17 lose their limiting effect. At this time, the first handwheel 25 is rotated in the opposite direction, and the first valve seat 15 and the second valve seat 16 will move in the opposite direction to open the cylinder. At this time, the clamp 6 is loosened, and after the pressure is lost at the connection between the cylinder body 1 and the cylinder cover 2, the cylinder cover 2 can be rotated to open, realizing quick opening and improving flexibility and convenience.

[0027] Please see Figure 1 , 4 The lower end of the rotating part of the clamp 6 is provided with a support seat 26, and the support seat 26 is welded and fixed to the cylinder 1. The clamp 6 is fixed to the support seat 26 by external bolts, and the support seat 26 supports the clamp 6.

[0028] Please see Figure 1 The lower end of the clamp 6 is provided with a stabilizing plate 10, and one end of the stabilizing plate 10 is welded and fixed to the cylinder 1. The stabilizing plate 10 supports the clamp 6. At the same time, the stabilizing plate 10 has an L-shaped structure, which limits the clamp 6 and prevents it from falling, thereby improving stability and safety.
