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.

[0024] like Figures 1 to 3 As shown, the present invention provides a special cement production feed hopper with a pretreatment structure, including a pretreatment feed hopper body 1, a feed inlet 2 and a discharge box 3. The feed inlet 2 is opened at the top of the pretreatment feed hopper body 1, the pretreatment box is installed at the bottom of the pretreatment feed hopper body 1, a connecting and concentrating component 4 is opened on the outside of the pretreatment feed hopper body 1, and a filter detection component 5 is installed at the bottom of one side of the pretreatment feed hopper body 1.

[0026] As a technical optimization of this utility model, by setting up a connecting and concentrating component 4, a centrifugal fan 45 can be started during use. The suction end of the centrifugal fan 45 generates suction force on the inside of the concentrating box 44. The suction force draws in dust and impurities in the pretreatment feeding hopper body 1 through the concentrating pipe 43 and the movable groove 41. At the same time, the filter ring 42 in the movable groove 41 initially intercepts the material to prevent the material from entering the concentrating pipe 43 and reaching the concentrating box 44, which would cause the concentrating box 44 to become blocked. The concentrating pipe 43 introduces air containing dust into the concentrating box 44, and the centrifugal fan 45 provides suction force to realize the collection and guidance of dust in the pretreatment feeding hopper body 1, which facilitates subsequent filtration.

[0027] refer to Figure 3 The filter detection component 5 includes a filter box 51, a movable groove 52 is provided on the front of the filter box 51, a filter plate 57 is installed inside the movable groove 52, an exhaust pipe 53 is installed at the bottom of the filter box 51, a first dust concentration sensor 54 is installed inside the exhaust pipe 53, a second dust concentration sensor 55 is installed on the top of the pretreatment feeding hopper body 1, and a controller 56 is installed on the front of the pretreatment feeding hopper body 1. The controller 56 is electrically connected to the centrifugal fan 45, the first dust concentration sensor 54 and the second dust concentration sensor 55 through wires.

[0028] As a technical optimization of this utility model, by setting up a filter detection component 5, the filter plate 57 in the moving groove 52 on the front of the filter box 51 filters dust and impurities during use. The first dust concentration sensor 54 in the bottom exhaust pipe 53 monitors the dust concentration of the exhaust air in real time, and the second dust concentration sensor 55 on the top of the feeding hopper body monitors the overall dust concentration in the feeding hopper and sends the detection data to the controller 56, so that the controller 56 can adjust the output efficiency of the centrifugal fan 45 and achieve precise control of the dust removal process.

[0029] refer to Figure 2 The back of the filter box 51 is connected to the collection box 6, the inside of the collection box 6 is movably connected to the collection box 7, and the back of the collection box 7 is equipped with a movable block 8.

[0030] As a technical optimization of this utility model, by setting up a collection box 6, a collection container 7 and a moving block 8, the collection box 6 is used to temporarily store the filtered dust, the collection container 7 can be taken out from the collection box 6 for easy cleaning of dust, and the moving block 8 makes it easy to pull the collection container 7, which improves the convenience of cleaning dust and ensures the continuous and stable operation of the equipment.

[0031] refer to Figure 3 A push plate 9 is provided on the front side of the top of the filter plate 57. An electric push rod 10 is installed on the front of the push plate 9. The electric push rod 10 is installed on the front of the filter plate 57 and is electrically connected to the controller 56 through a wire.

[0032] As a technical optimization of this utility model, by setting up a push plate 9 and an electric push rod 10, the controller 56 can start the electric push rod 10 during use, so that the electric push rod 10 pushes the push plate 9. The movement of the push plate 9 can push the impurities filtered on the top of the filter plate 57 to move towards the collection box 6, so that the filtered impurities can be collected and cleaned.

[0033] refer to Figure 2 The output end of the centrifugal fan 45 is connected to a fixed pipe 11, and a solenoid valve 12 is installed at the other end of the fixed pipe 11. The solenoid valve 12 is installed on the top of the filter box 51.

[0034] As a technical optimization of this utility model, by setting a fixed pipe 11 and a solenoid valve 12, the fixed pipe 11 at the output end of the centrifugal fan 45 introduces the air in the central box 44 into the filter box 51. The solenoid valve 12 controls the air flow, which makes it convenient to shut off the air flow when cleaning impurities on the filter plate 57. The filtration process can be flexibly adjusted according to actual needs to improve the adaptability of the equipment.

[0035] refer to Figure 3A moving rod 13 is installed on the back of the push plate 9, and a collection groove 14 is opened on the front of the collection box 6. Several collection grooves 14 are provided, and the several collection grooves 14 are arranged at equal distances.

[0036] As a technical optimization of this utility model, by setting a moving rod 13 and a collection groove 14, the collection groove 14 can facilitate the pushing plate 9 to push dust and impurities into the interior of the collection box 6, and the moving rod 13 can facilitate the pushing plate 9 to push the sealing plate 16 to move, so that dust and impurities can enter the interior of the collection box 6.

[0037] refer to Figure 3 A torsion spring 15 is installed on the top of the inner wall of the collection tank 14, and a sealing plate 16 is installed on the other end of the torsion spring 15.

[0038] As a technical optimization of this utility model, by setting a torsion spring 15 and a sealing plate 16, the torsion spring 15 can drive the sealing plate 16 to seal the collection groove 14. When the push plate 9 pushes and cleans the dust and impurities on the top of the filter plate 57, the moving rod 13 can be pushed to push the front of the sealing plate 16, so that the sealing plate 16 opens the collection groove 14 under the limit of the torsion spring 15, making it convenient for dust and impurities to enter the interior of the collection box 6 and be collected and cleaned.

[0039] The working principle and usage process of this utility model are as follows: During use, the centrifugal fan 45 is activated, generating suction at its suction end inside the collection box 44. This suction acts on the pretreatment feeding hopper body 1 through the collection pipe 43 and the movable groove 41. Dust and impurities generated within the pretreatment feeding hopper body 1 are sucked in under the suction. The filter ring 42 in the movable groove 41 intercepts the material, preventing it from entering the collection pipe 43 and clogging the collection box 44. The collection pipe 43 introduces dusty air into the collection box 44, completing the initial collection and guidance of dust within the pretreatment feeding hopper body 1, preparing for subsequent filtration. The dusty air enters the filter box 51 through the fixed pipe 11 via the centrifugal fan 45. The filter plate 57 in the movable groove 52 on the front of the filter box 51 further filters the dust and impurities. Simultaneously, the first dust concentration sensor 54 in the exhaust pipe 53 monitors the dust concentration of the exhaust air in real time, and the second dust concentration sensor 55 at the top of the pretreatment feeding hopper body 1 monitors the overall dust concentration within the feeding hopper. The sensor sends the detection data to the controller 56. The controller 56 adjusts the output efficiency of the centrifugal fan 45 according to the data. If the dust concentration in the hopper is too high, the controller 56 increases the suction of the centrifugal fan 45 to enhance the dust removal effect. If the dust concentration in the discharged air does not meet the standard, the filter plate 57 can be replaced after observation by the user, thus achieving precise control of the dust removal process. When it is necessary to clean the impurities on the filter plate 57, the controller 56 starts the electric push rod 10. The electric push rod 10 pushes the push plate 9. The push plate 9 moves the impurities filtered on the top of the filter plate 57 to the collection box 6. The moving rod 13 on the back of the push plate 9 pushes the sealing plate 16, so that the sealing plate 16 opens the collection groove 14 under the limit of the torsion spring 15. The impurities enter the collection box 7 in the collection box 6 through the opened collection groove 14 for temporary storage. When cleaning, the moving block 8 on the back of the collection box 7 can be pulled to remove the collection box 7 from the collection box 6 for easy cleaning of dust, ensuring the continuous and stable operation of the equipment, achieving the effect of dust removal and filtration, and enhancing the use effect of the pretreatment hopper.

[0040] In summary, this special cement production feed hopper with a pretreatment structure solves the problem of existing pretreatment feed hoppers being unable to perform dust removal and filtration during use. This is achieved by setting up a connecting and centralized component 4 in conjunction with a filter and detection component 5 to collect, filter, and remove dust particles generated inside the pretreatment feed hopper body 1. This solves the problem of existing pretreatment feed hoppers being unable to perform dust removal and filtration during use, which leads to a large amount of dust being generated inside the pretreatment feed hopper during use. This not only affects the surrounding environment but also the health of the workers, causing inconvenience during use and reducing the effectiveness of the pretreatment feed hopper.
