[0020] 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.

[0021] Please see Figures 1-6 As shown, a chemical feeding device with a safety protection structure includes a storage tank 1, a discharge port 3 at the lower end of the storage tank 1, and a cover plate 2 rotatably installed at the upper end of the storage tank 1. The device is characterized by: a crushing component 4 inside the storage tank 1, which can crush some caking chemical raw materials to prevent them from affecting production quality; a motor 5 for driving the crushing component 4 on one side of the storage tank 1; an air pump 6 on the storage tank 1 and located on the side of the motor 5; a mounting cover 7 and a collection cover 8 on both sides of the storage tank 1; an adjustable cleaning component 9 on the mounting cover 7, which is connected to the output end of the air pump 6; a filter plate 10 with a certain inclination angle slidably engaged inside the storage tank 1 and below the crushing component 4; and the adjustable cleaning component 9 located above the filter plate 10. The crushed material is screened through the filter plate 10 and discharged through the discharge port 3 at the lower end of the storage tank 1 to enter subsequent production stages. Larger particles that fail to pass through the filter plate 10 fall into the collection cover 8 under gravity.

[0022] The storage bin 1 is equipped with a guide plate 11. The crushing assembly 4 includes a first crushing roller 401 and a second crushing roller 402. Both the first crushing roller 401 and the second crushing roller 402 are rotatably installed inside the storage bin 1 and located below the guide plate 11. The first crushing roller 401 is fixedly connected to the output end of the first motor 5. Rotating gears 403 are provided on the first crushing roller 401 and the second crushing roller 402. The rotating gears 403 mesh with each other. When the motor 5 rotates, it drives the first crushing roller 401 to rotate. The rotating gears 403 on the first crushing roller 401 mesh with the rotating gears 403 on the second crushing roller 402, thereby driving the second crushing roller 402 to rotate synchronously in the opposite direction. Under the high-speed rotation of the first crushing roller 401 and the second crushing roller 402, the raw materials are rapidly crushed.

[0023] The adjustable cleaning assembly 9 includes a threaded rod 901, which is threadedly connected to the mounting cover 7. A mounting plate 902 is rotatably mounted on the other end of the threaded rod 901, and a handwheel 903 is fixedly mounted on the other end. Limiting rods 904 are connected to the mounting plate 902 on both sides of the threaded rod 901, and the limiting rods 904 are inserted into the mounting cover 7. Cleaning brushes 905 arranged in an array are connected to the mounting plate 902. Rotating the handwheel 903 rotates the threaded rod 901. Due to the limitation of the limiting rods 904, the mounting plate 902 moves up and down along the direction of the limiting rods 904, adjusting the cleaning brushes 905 and the air blower head 908 to a suitable position. The height is adjusted so that it is close to the surface of the filter plate 10. A horizontal pipe 906 is provided on one side of the mounting plate 902. An air inlet pipe 907 is connected to the horizontal pipe 906. The other end of the air inlet pipe 907 is connected to the output end of the air pump 6. An array of air blowing heads 908 are connected to the horizontal pipe 906. When the air pump 6 is started, the air pump 6 delivers high-pressure gas to the horizontal pipe 906 through the air inlet pipe 907. The high-pressure gas is blown out from the array of air blowing heads 908 on the horizontal pipe 906 to blow off some material remaining in the filter holes of the filter plate 10, so as to avoid clogging of the filter plate 10 and affecting screening. A baffle 12 is snapped onto the mounting cover 7 and the collection cover 8. A handle is connected to the baffle 12.

[0024] In use, the cover plate 2 is opened, and the chemical raw materials to be fed are placed through the guide plate 11, allowing the raw materials to fall evenly onto the crushing component 4, facilitating subsequent crushing operations. The motor 5 is started, driving the first crushing roller 401 to rotate. The rotating gear 403 on the first crushing roller 401 meshes with the rotating gear 403 on the second crushing roller 402, thereby driving the second crushing roller 402 to rotate synchronously in the opposite direction. Under the high-speed rotation of the first and second crushing rollers 401 and 402, the raw materials are rapidly crushed. The crushed material falls onto the filter plate 10 under gravity, where it is screened and discharged through the outlet 3 at the lower end of the storage box 1, entering subsequent production stages. Larger particles that fail to pass through the filter plate 10 are then further screened. Under the action of force, the material falls into the collection hood 8. As the feeding process continues, residual material will gradually accumulate on the filter plate 10. At this time, cleaning needs to be started to avoid affecting subsequent screening. Turn the handwheel 903, and the threaded rod 901 will rotate. Due to the restriction of the limit rod 904, the mounting plate 902 moves up and down along the direction of the limit rod 904. Adjust the cleaning brush 905 and the air blowing head 908 to a suitable height so that they are close to the surface of the filter plate 10. Start the air pump 6. The air pump 6 delivers high-pressure gas to the transverse pipe 906 through the air inlet pipe 907. The high-pressure gas is blown out from the air blowing heads 908 arranged in an array on the transverse pipe 906 to blow off some material remaining in the filter holes on the filter plate 10. Pull the filter plate 10 to clean the entire surface of the filter plate 10.
