[0017] 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.

[0018] Please see Figure 1-5 The present invention provides the following technical solution: A premixed filtration structure for anti-clogging sponge production raw materials includes a mixing tank 1, a multi-stage mixing mechanism 2 is provided inside the mixing tank 1, a feeding pipe 3 is fixedly connected to the bottom right side of the mixing tank 1, a filter box 4 is fixedly connected to the right side of the feeding pipe 3, a discharge pipe 5 is fixedly connected to the bottom front side of the filter box 4, a filter plate 6 is inclinedly arranged inside the filter box 4, and a pulse declogging component 7 is provided on the top of the filter box 4. The pulse declogging component 7 includes a pulse controller 71 and a high-pressure air pump 72. The bottoms of the pulse controller 71 and the high-pressure air pump 72 are respectively bolted to the top of the filter box 4. A high-pressure pulse air supply pipe 73 is fixedly connected to the front side of the high-pressure air pump 72. The other end of the high-pressure pulse air supply pipe 73 is fixedly connected to the bottom of the front side of the filter box 4. A first electrically controlled ball valve 74 is installed inside the high-pressure pulse air supply pipe 73.

[0019] In this embodiment: During the sponge production process, different sponge production raw materials are first added to the mixing tank 1 through the raw material feed pipe 14. The multi-stage mixing mechanism 2 inside the mixing tank 1 starts working to fully mix the raw materials. After the mixture is evenly mixed, the second electrically controlled ball valve 9 inside the feed pipe 3 is opened, and the mixed raw materials flow into the filter box 4 through the feed pipe 3. Inside the filter box 4, the inclined filter plate 6 filters the raw materials, intercepting impurities and unqualified particles. The qualified raw materials after filtration flow out from the discharge pipe 5 and can enter the subsequent sponge production process. After each filtration, the pulse deblocking component 7 is started. The pulse controller 71 controls the high-pressure air pump 72 to work and opens the first electrically controlled ball valve 74 inside the high-pressure pulse air supply pipe 73. High-pressure gas enters the bottom of the front side of the filter box 4 through the high-pressure pulse air supply pipe 73 and impacts the filter plate 6 with pulse high-pressure airflow to remove blockages.

[0020] Specifically, such as Figure 2 As shown, the multi-stage stirring mechanism 2 includes a stirring shaft 21, which is rotatably disposed inside the stirring tank 1.

[0021] Specifically, such as Figure 2 As shown, the surface of the stirring shaft 21 is fitted with threaded blades 22 arranged opposite to each other. The surface of the threaded blades 22 is provided with several protrusions 23. Several stirring rods 24 are bolted to the front and rear sides of the stirring shaft 21. The stirring rods 24 are welded to the two threaded blades 22 on the side closest to the two threaded blades 22 respectively.

[0022] Specifically, such as Figure 2 As shown, a stirring motor 8 is bolted to the bottom of the mixing tank 1, and the output shaft of the stirring motor 8 extends into the mixing tank 1 and is bolted to the stirring shaft 21.

[0023] In this embodiment: when the raw materials for sponge production enter the mixing tank 1 through the raw material feed pipe 14, the mixing motor 8 starts to operate. The output shaft of the mixing motor 8 drives the mixing shaft 21 to rotate. The threaded blades 22, which are arranged opposite each other and are sleeved on the surface of the mixing shaft 21, rotate accordingly. During the rotation, the several protrusions 23 on the surface of the threaded blades 22 can enhance the mixing effect on the raw materials, making the raw materials generate a more complex flow in the mixing tank 1. At the same time, the several mixing rods 24 bolted to the front and rear sides of the mixing shaft 21 also rotate with the mixing shaft 21. Since the side of the mixing rod 24 closest to the two threaded blades 22 is welded to the two threaded blades 22 respectively, the mixing rods 24 and the threaded blades 22 work together to further improve the uniformity of mixing. During the mixing process, different raw materials are fully mixed under the action of the multi-stage mixing mechanism 2, providing uniform raw materials for subsequent filtration and sponge production.

[0024] Specifically, such as Figure 3 , Figure 4As shown, a second electrically controlled ball valve 9 is installed inside both the feeding pipe 3 and the discharge pipe 5. An exhaust pipe 10 is fixedly connected to the right side of the top of the filter box 4, and a sealing cap 11 is threadedly connected to the top of the surface of the exhaust pipe 10.

[0025] Specifically, such as Figure 5 As shown, an auxiliary filter pressurization pipe 12 is fixedly connected between the right side of the high-pressure air pump 72 and the top of the filter box 4, and a vibration motor 13 is bolted to the bottom of the filter plate 6.

[0026] In this embodiment: During the filtration process, the second electrically controlled ball valve 9 inside the feed pipe 3 and the discharge pipe 5 controls the inflow and outflow of the raw material. When the raw material enters the filter box 4 for filtration, the second electrically controlled ball valve 9 inside the feed pipe 3 can be closed when the filtration speed slows down. The high-pressure air pump 72 pressurizes the filter box 4. During pressurization, the high-pressure air pump 72 delivers gas to the top of the filter box 4 through the auxiliary filtration pressurization air pipe 12, increasing the pressure inside the filter box 4 and improving the filtration efficiency. At the same time, the vibration motor 13 bolted to the bottom of the filter plate 6 can be turned on, causing the filter plate 6 to vibrate. This helps to speed up the filtration process and prevent filter residue from accumulating on the filter plate 6, further reducing the possibility of clogging. After this filtration is completed, the pulse declogging component 7 can be activated to clear the blockage. The second electrically controlled ball valve 9 of the feed pipe 3 and the discharge pipe 5 is closed to ensure that a relatively sealed space is formed inside the filter box 4. At the same time, the sealing cover 11 with the threaded connection on the top right side of the exhaust pipe 10 at the top of the filter box 4 is opened, so that the high-pressure flushing airflow flows out from the exhaust pipe 10 through the filter plate 6, forming a fixed flushing channel. At the same time, the vibration of the vibration motor 13 makes the pulse declogging effect even better.

[0027] Specifically, such as Figure 1 , Figure 5 As shown, the top of the mixing tank 1 is fixedly connected to several raw material feed pipes 14, the top of the right side of the filter box 4 is provided with a filter observation window 15, the right side of the filter box 4 is bolted with a filter residue collection box 16, the left side of the filter residue collection box 16 is connected to the filter box 4, and the right side of the filter residue collection box 16 is provided with a slag discharge door 17.

[0028] Specifically, such as Figure 1 As shown, a placement rack 18 is bolted to the bottom of the mixing tank 1, a base plate 19 is bolted to the bottom of the placement rack 18, and the top of the base plate 19 is bolted to the bottom of the filter box 4.

[0029] In this embodiment: During the operation of the entire premixing and filtration structure for sponge production raw materials, the mixing tank 1 is placed on the base plate 19 via the bottom placement rack 18. The filter box 4 is bolted to the top of the base plate 19, resulting in a difference in height between the mixing tank 1 and the filter box 4. This allows the mixed raw materials to flow into the filter box 4 under the action of gravitational potential energy. Multiple sponge production raw materials simultaneously enter the mixing tank 1 through several raw material feed pipes 14 fixedly connected to the top of the mixing tank 1 for mixing. The filter observation window 15 on the top right side of the filter box 4 allows the operator to easily observe the filtration situation inside the filter box 4 and promptly detect any filtration abnormalities. As filtration proceeds, the filter residue intercepted by the filter plate 6 slides down the inclined filter plate 6 into the filter residue collection box 16. When a certain amount of filter residue is collected, the slag discharge door 17 on the right side of the filter residue collection box 16 is opened to discharge the filter residue. Under stable support, the entire structure continuously and efficiently completes the premixing and filtration of sponge production raw materials.

[0030] Working Principle: During the operation of the premixed filtration structure for sponge production raw materials, multiple sponge production raw materials simultaneously enter the mixing tank 1 through several raw material feed pipes 14 at the top of the mixing tank 1. The stirring motor 8 operates, and its output shaft drives the stirring shaft 21 to rotate. The relatively threaded blades 22 sleeved on the stirring shaft 21 rotate, and the protrusions 23 on the surface of the blades enhance the stirring effect. The stirring rods 24 on the front and rear sides of the stirring shaft 21 also rotate accordingly and work in coordination with the threaded blades 22. The multi-stage stirring mechanism 2 fully mixes the raw materials. After the materials are evenly mixed, the second electrically controlled ball valve 9 in the feeding pipe 3 is opened. Due to the height difference between the mixing tank 1 and the filter box 4 (the mixing tank 1 is placed on the base plate 19 through the bottom placement frame 18, and the filter box 4 is bolted to the top of the base plate 19), the mixed raw materials flow into the filter box 4 through the feeding pipe 3 by gravity potential energy. In the filter box 4, the inclined filter plate 6 filters the raw materials, intercepting impurities and unqualified particles. Qualified raw materials flow out from the discharge pipe 5 to enter the subsequent process. During filtration, the second electrically controlled ball valve 9 in the feeding pipe 3 and the discharge pipe 5 controls the entry and exit of the raw materials. If the filtration speed slows down, the second electrically controlled ball valve 9 of the feed pipe 3 is closed. The high-pressure air pump 72 sends air to the top of the filter box 4 through the auxiliary filter pressurization pipe 12 to increase the filtration efficiency. At the same time, the vibration motor 13 at the bottom of the filter plate 6 can be turned on to make the filter plate 6 vibrate, which speeds up the filtration speed and prevents the filter residue from accumulating. After each filtration is completed, the pulse declogging component 7 is started, the second electrically controlled ball valve 9 of the feed pipe 3 and the discharge pipe 5 is closed, the sealing cover 11 of the exhaust pipe 10 at the top of the filter box 4 is opened, the pulse controller 71 controls the high-pressure air pump 72 to work, and the first electrically controlled ball valve 74 in the high-pressure pulse air supply pipe 73 is opened. The high-pressure gas enters the bottom of the filter box 4 to impact the filter plate 6 with pulse high-pressure airflow. The vibration motor 13 vibrates to clear the blockage. In addition, the filter observation window 15 makes it convenient for the operator to observe the filtration situation. The intercepted filter residue slides down the inclined filter plate 6 into the filter residue collection box 16. When a certain amount is collected, the slag discharge door 17 is opened to discharge the filter residue. The entire structure is stably supported and continuously and efficiently completes the premixing and filtration of raw materials.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
