[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] Please refer to Figures 1 to 3This utility model provides an anti-clogging device for the inlet of a sulfur slurry pump, comprising a first connecting pipe 5, a connecting cylinder 2, a filter barrel 3, and a crushing component 4. The connecting cylinder 2 houses the filter barrel 3 and serves as the outer shell of the anti-clogging device. The side walls and bottom of the filter barrel 3 are mesh-like. The filter barrel 3 is connected to the inlet pipe 1 via the first connecting pipe 5. The filter barrel 3 filters the medium flowing into it, trapping clumps in the medium and crushing them within the filter barrel 3 to prevent clumps from flowing into the sulfur slurry pump and causing blockage. The crushing component 4 is located inside the filter barrel 3 and is driven to rotate by a connected motor 8 to crush clumps in the medium within the filter barrel 3.

[0026] To better implement this utility model, refer to Figure 1 In one embodiment, a pressure cap 6 is also included, which is disposed at the top of the connecting cylinder 2, and a motor 8 is mounted on the top of the pressure cap 6. A quick flange is provided circumferentially at the top of the filter barrel 3, and a quick flange is provided circumferentially on the connecting cylinder 2. The quick flange of the filter barrel 3 is installed between the quick flange of the connecting cylinder 2 and the pressure cap 6, and the quick flange is used to install the filter barrel 3 inside the connecting cylinder 2.

[0027] To better implement this utility model, refer to Figure 2 In one embodiment, the crushing assembly 4 includes a rotating shaft 401, crushing blades 402, and a scraper 403. The upper end of the rotating shaft 401 is connected to the output end of the motor 8 that passes through the pressure cover 6. The lower end of the rotating shaft 401 is rotatably mounted on the bottom of the filter barrel 3. The rotating shaft 401 and the motor 8 are connected by a coupling or bushing. Multiple crushing blades 402 are connected to the rotating shaft 401 via connecting rods. The lower part of the rotating shaft 401 is provided with a scraper 403, which abuts against the bottom of the filter barrel 3. In this embodiment, two crushing blades 402 are provided to crush lumps in the medium, so as to facilitate the flow of the medium into the sulfur slurry pump and avoid damage to the sulfur slurry pump. During rotation, the scraper 403 can not only crush lumps but also scrape off blocky particles that may be deposited on the bottom surface of the filter barrel 3, keeping the sieve holes of the filter barrel 3 unobstructed.

[0028] The crushing blade 402 can also be set to abut against the side wall of the filter barrel 3 and be set at an angle to the bottom of the filter barrel 3, so as to ensure that the clumps are crushed while avoiding the side wall of the filter barrel 3 being blocked.

[0029] Motor 8 drives crushing component 4 to crush and stir the medium inside filter barrel 3, so that the particles in the medium are more evenly distributed. When the solid particles are more evenly distributed, the resistance of the fluid passing through the sieve holes of filter barrel 3 is reduced, thereby increasing the filtration speed.

[0030] The crushing component 4 is rotatably mounted on the bottom of the filter barrel 3. When disassembling the filter barrel 3, the filter barrel 3 and the crushing component 4 are removed from the connecting cylinder 2 as a whole. The rotating shaft 401 of the crushing component 4 is detachable from the output end of the motor 8. Alternatively, the crushing component 4 can be directly connected to the output end of the motor 8, meaning that when the pressure cap 6 is removed, the motor 8 and the crushing component 4 can be removed together. In this configuration, the lower end of the rotating shaft 401 is not connected to the bottom of the filter barrel 3, but the scraper 403 on the rotating shaft 401 still abuts against the bottom of the filter barrel 3. In this embodiment, it is preferable that the filter barrel 3 and the crushing component 4 are installed as a single unit.

[0031] To better implement this utility model, refer to Figure 1 In one embodiment, a second connecting pipe 7 is further included. The second connecting pipe 7 is used to connect the connecting cylinder 2 and the sulfur slurry pump. In order to achieve the purpose of first breaking up the agglomerates in the medium in the filter tank 3, and then sending the broken agglomerates in the filter tank 3 into the sulfur slurry pump through the second connecting pipe 7, in this embodiment, the second connecting pipe 7 is preferably located at the bottom of the connecting cylinder 2 and directly below the filter tank 3. The second connecting pipe 7 may also be located on the lower part of the side wall of the connecting cylinder 2.

[0032] To better implement this utility model, refer to Figure 3 In one embodiment, the inlet pipe 1 and the side wall of the connecting cylinder 2 are connected by threads or welding. In this embodiment, for ease of disassembly and inspection of the connecting cylinder 2, it is preferable that the inlet pipe 1 and the connecting cylinder 2 are connected by threads. To prevent the medium in the filter barrel 3 from flowing back into the inlet pipe 1, the inlet pipe 1 can be located on the upper part of the side wall of the connecting cylinder 2. The inlet pipe 1 is used to transport the medium into the filter barrel 3. One end of the connecting pipe extends into the filter barrel 3 from the opening on the side wall of the filter barrel 3, and the other end extends into the mounting groove 10 on the side wall of the connecting cylinder 2. The mounting groove 10 is provided with multiple elastic elements 9. One end of each elastic element 9 is connected to the mounting groove 10, and the other end is connected to the first connecting pipe 5. A limiting ring can also be connected to one end of the connecting pipe located in the mounting groove 10. The limiting ring is connected to one end of the elastic element 9 and is used to prevent the connecting pipe from coming out of the mounting groove 10. In this embodiment, four elastic elements 9 are provided to ensure the stability of the connecting pipe.

[0033] The first connecting pipe 5 is located on the inner wall of the connecting cylinder 2, and the first connecting pipe 5 is sleeved on the circumferential direction of the opening where the liquid inlet pipe 1 connects to the side wall of the connecting cylinder 2. That is, an installation groove 10 is provided on the circumferential direction of the opening where the liquid inlet pipe 1 connects to the side wall of the connecting cylinder 2, so that the medium enters the first connecting pipe 5 along the liquid inlet pipe 1 and continues to enter the interior of the filter barrel 3 along the first connecting pipe 5.

[0034] During operation, the first connecting pipe 5 also serves to stabilize the filter barrel 3. If the filter barrel 3 is installed solely via a quick flange, when the crushing assembly 4 is driven by the motor 8, the liquid and mixed clumps inside the filter barrel 3 will collide with the filter barrel 3 during the crushing process, inevitably affecting it. Therefore, the first connecting pipe 5, while connecting the inlet pipe 1 to the filter barrel 3, also increases the connection point between the filter barrel 3 and the connecting cylinder 2. Simultaneously, the first connecting pipe 5 facilitates the quick installation of the filter barrel 3. When the first connecting pipe 5 extends into the opening on the side wall of the filter barrel 3, it indicates that the filter barrel 3 is properly installed. The positioning pin can then be inserted into the quick flange to install the filter barrel 3. This design facilitates quick installation of the filter barrel 3 by the operator, avoiding the need for multiple alignment attempts if the opening on the side wall of the filter barrel 3 is directly connected to the inlet pipe 1, thus reducing the installation difficulty of the filter barrel 3 and the first connecting pipe 5.

[0035] When the filter barrel 3 and the connecting cylinder 2 need to be installed, the opening on the side wall of the filter barrel 3 needs to be aligned with the liquid inlet pipe 1 so that the medium can flow into the filter barrel 3. To facilitate the quick connection between the filter barrel 3 and the liquid inlet pipe 1, a first connecting pipe 5 is provided between the filter barrel 3 and the liquid inlet pipe 1. When other parts of the side wall of the filter barrel 3 come into contact with the end of the first connecting pipe 5 away from the connecting cylinder 2, the first connecting pipe 5 will move into the mounting groove 10. At this time, the first connecting pipe 5 squeezes the elastic element 9 in the mounting groove 10 until the filter barrel 3 is adjusted so that the opening on the side wall of the filter barrel 3 is aligned with the first connecting pipe 5. At this time, the elastic force of the elastic element 9 pushes the first connecting pipe 5 into the opening on the side wall of the filter barrel 3, thereby connecting the filter barrel 3 and the liquid inlet pipe 1.

[0036] When it is necessary to remove the filter barrel 3 from the connecting cylinder 2, disassemble the quick flange of the filter barrel 3, and then manually squeeze the first connecting pipe 5 so that the first connecting pipe 5 comes out of the opening on the side wall of the filter barrel 3. Rotate the filter barrel 3, at which point the first connecting pipe 5 will abut against the outside of the side wall of the filter barrel 3. In this state, the filter barrel 3 can be separated from the first connecting pipe 5, thereby removing the filter barrel 3 from the connecting cylinder 2.

[0037] To better implement this utility model, refer to Figure 3 In one embodiment, the outer diameter of the first connecting pipe 5 is the same as the inner diameter of the opening on the inner wall of the filter barrel 3, and the inner diameter of the first connecting pipe 5 is larger than the outer diameter of the liquid inlet pipe 1, so as to ensure that the medium in the liquid inlet pipe 1 can flow into the filter barrel 3 through the first connecting pipe 5.

[0038] To better implement this utility model, refer to Figure 1In one embodiment, the distance between the bottom of the filter bucket 3 and the second connecting pipe 7 is 6 to 12 cm. In this embodiment, the preferred distance is 10 cm, so that the medium in the filter bucket 3 can enter the second connecting pipe 7 and flow to the sulfur slurry pump after the agglomerates in the crushing component 4 are broken up.

[0039] To better implement this utility model, refer to Figure 1 In one embodiment, the bottom of the pressure cap 6 is also provided with multiple positioning pins, which are used to achieve quick positioning and installation of the pressure cap 6 and the connecting cylinder 2. The positioning pins are threaded and are inserted into positioning holes that align with the quick flanges of the filter barrel 3 and the quick flanges of the connecting cylinder 2. The positions of the two quick flanges are limited by nuts fitted on the positioning pins, thereby fixing the filter barrel 3 and the connecting cylinder 2.

[0040] Based on the above-mentioned anti-clogging device for the sulfur slurry pump inlet, its working principle is as follows:

[0041] Before use, the filter barrel 3 and the connecting cylinder 2 need to be installed. Place the filter barrel 3 into the connecting cylinder 2. At this time, the side wall of the filter barrel 3 will squeeze the first connecting pipe 5 into the mounting groove 10. The elastic element 9 in the mounting groove 10 is in a compressed state. Adjust the filter barrel 3 so that the opening on the side wall of the filter barrel 3 is aligned with the first connecting pipe 5. Under the elastic force of the elastic element 9, the first connecting pipe 5 extends out of the mounting groove 10 and into the filter barrel 3, so that the liquid inlet pipe 1 is connected to the filter barrel 3 through the first connecting pipe 5. At this time, the quick flange at the upper end of the filter barrel 3 is installed at the top of the connecting cylinder 2 so that the quick flange of the filter barrel 3 is aligned with the positioning hole of the quick flange of the connecting cylinder 2. Insert the pressure cap 6 into the positioning hole through the positioning pin to seal the connecting cylinder 2. Connect the output end of the motor 8 installed on the pressure cap 6 to the rotating shaft 401 of the crushing component 4. To prevent water leakage at the connection between the connecting cylinder 2 and the gland 6, rubber gaskets can be installed between the gland 6 and the quick flange of the filter barrel 3, and between the quick flange of the filter barrel 3 and the quick flange of the connecting cylinder 2.

[0042] The inlet pipe 1 sends the medium into the filter barrel 3 through the first connecting pipe 5. The motor 8 is started, and the motor 8 drives the rotating shaft 401 to rotate, thereby driving the crushing blade 402 connected to the rotating shaft 401 through the connecting rod to crush the lumps in the medium. At the same time, the rotation of the rotating shaft 401 also drives the scraper 403 to scrape off the lumps attached to the bottom of the filter barrel 3, so as to prevent the screen holes of the filter barrel 3 from being blocked. The crushed lumps can pass through the filter barrel 3 with the liquid and can be sent to the sulfur slurry pump without blocking the second connecting pipe 7.

[0043] When the filter canister 3 is damaged and needs to be replaced, or when the filter canister 3 needs to be removed for cleaning periodically, open the pressure cap 6 and manually press the first connecting pipe 5 out of the filter canister 3 so that the first connecting pipe 5 is separated from the opening on the side wall of the filter canister 3, and remove the filter canister 3 from the connecting cylinder 2.

[0044] Although the present invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
