Description

Technical Field

[0001] This utility model belongs to the technical field of supporting equipment for crushing stone processing, specifically a dust removal device for crushing stone rotund screen. Background Technology

[0002] Crushed stone is a common building material in construction and other scenarios. For example, it is used as a main building material and mixed with concrete. Crushed stone needs to go through many steps from mining to final use in order to meet the usage standards. For example, crushed stone is screened according to its particle size. A trommel screen is one of the commonly used devices for screening crushed stone.

[0003] When existing crushed stone roller screens are in use, they generally use the inclined setting of the roller screen and the rotation to drive the crushed stone to move in and screen it at the same time. However, in actual application, since the crushed stone is in the processing stage, some dust is often attached to it. Therefore, a large amount of dust can easily be generated during the screening process, which seriously affects the on-site working environment. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a dust removal device for a stone crushing roller screen, which solves the problem that existing stone crushing roller screens easily cause a large amount of dust to spread during use, affecting the working environment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dust removal device for a stone crushing rotary screen, comprising a dust cover installed on the top of the main body of the stone crushing rotary screen, a sealed chamber installed on the top of the dust cover, and the sealed chamber and the dust cover being connected by an air inlet pipe, and a conveying mechanism for driving air into the sealed chamber is provided on the dust cover.

[0006] The top of the sealed chamber is equipped with a closed cover, and the bottom of the sealed chamber is provided with a collection scraper chamber. Both the bottom of the closed cover and the bottom of the collection scraper chamber are provided with fitting grooves. A filter plate is provided inside the fitting groove, and a limit groove is reserved on the top and bottom of one side of the filter plate.

[0007] Both the closed cover and the collection scraper compartment have receiving grooves on one side and a limiting mechanism for fixing the filter plate inside the receiving groove.

[0008] As a further embodiment of this utility model: the conveying mechanism includes an exhaust fan, the exhaust fan is installed on one side of the dust cover, the input end of the exhaust fan is connected to a vent pipe, and the end of the vent pipe away from the exhaust fan is connected to a sealed chamber, the output end of the exhaust fan is connected to an exhaust pipe, and the end of the exhaust pipe away from the exhaust fan is connected to the dust cover.

[0009] As a further embodiment of this utility model: the cross-sectional shape of the closed cover is "T" shaped, and the closed cover and the sealing chamber are installed by screws and nuts.

[0010] As a further embodiment of this utility model: the opening at the top of the collecting scraper bin is open, and the collecting scraper bin and the sealing bin form a relatively sliding structure.

[0011] As a further embodiment of this utility model: the limiting mechanism includes a limiting rod, which passes through one side of the receiving groove and extends into the interior of the limiting groove. An external threaded ring is installed on the outer side of the limiting rod near the receiving groove.

[0012] As a further embodiment of this utility model: the central axis of the external threaded ring coincides with the central axis of the limiting rod, and the two sets of external threaded rings are respectively threadedly connected to the closed cover and the collection scraper bin.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The main body of the crushing roller screen is equipped with a dust cover, which can provide initial protection against the spread of dust generated by the crushing roller screen. The sealed chamber is equipped with an air inlet pipe for connecting the dust cover, and the dust cover is equipped with a conveying mechanism that connects the sealed chamber and the dust cover. During use, the dust can be carried into the sealed chamber for collection by driving airflow. At the same time, since the air is driven to circulate within the dust cover and the sealed chamber, the impact of airflow on the outside is further reduced.

[0015] 2. The open-type opening of the collection scraper bin allows the operator to remove the cover from the sealed bin and lift the cover to scrape the inner wall of the sealed bin, carrying away the collected dust. This facilitates subsequent processing of the collected dust. Furthermore, after the collection scraper bin is removed from the sealed bin, the limiting mechanism can release the filter plate from the cover and the collection scraper bin, making it easier for the operator to maintain and replace the filter plate.

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution:

[0024] Example 1

[0025] A dust removal device for a crushed stone rotary screen includes a dust cover 2 installed on the top of the crushed stone rotary screen body 1, which is the same as the existing crushed stone rotary screen of the same type.

[0026] A sealed chamber 3 is installed on the top of the dust cover 2, and the sealed chamber 3 is connected to the dust cover 2 through an air inlet pipe 4. The dust cover 2 is equipped with a conveying mechanism for driving air into the sealed chamber 3. The conveying mechanism includes an exhaust fan 5, which is installed on one side of the dust cover 2. The input end of the exhaust fan 5 is connected to a vent pipe 6, and the end of the vent pipe 6 away from the exhaust fan 5 is connected to the sealed chamber 3. The output end of the exhaust fan 5 is connected to an exhaust pipe 7, and the end of the exhaust pipe 7 away from the exhaust fan 5 is connected to the dust cover 2. When the exhaust fan 5 is turned on, the exhaust fan 5 can drive the air in the space formed by the main body 1 of the crushing rotary screen and the dust cover 2 into the sealed chamber 3 through the vent pipe 6, and then re-enter the space formed by the main body 1 of the crushing rotary screen and the dust cover 2 through the air inlet pipe 4, thereby forming a circulation flow and reducing the impact on the external environment.

[0027] The top of the sealed chamber 3 is equipped with a closed cover 8, and the bottom of the sealed chamber 3 is provided with a collection scraper chamber 9. Both the bottom of the closed cover 8 and the bottom of the collection scraper chamber 9 are provided with fitting grooves 10. The fitting grooves 10 are provided with filter plates 11, and the top and bottom of one side of the filter plates 11 are reserved with limiting grooves 12. When the exhaust fan 5 drives the air to circulate in the space formed by the crushing roller screen body 1 and the dust cover 2 and the sealed chamber 3, the dust generated by the crushing roller screen body 1 can enter the sealed chamber 3 with the air through the filter part on the crushing roller screen body 1 and be blocked in the sealed chamber 3 by the filter plate 11, thereby completing the collection of dust.

[0028] Example 2

[0029] Based on the above embodiment 1, the cross-sectional shape of the sealing cover 8 is "T" shaped, and the sealing cover 8 and the sealing chamber 3 are installed by screws and nuts, so that the staff can release the fixing between the sealing cover 8 and the sealing chamber 3, and open the sealing chamber 3 through the sealing cover 8 to maintain the inside of the sealing chamber 3.

[0030] The top opening of the collecting scraper bin 9 is open, and the collecting scraper bin 9 and the sealing bin 3 form a relative sliding structure, so that when the collecting scraper bin 9 is taken out from the sealing bin 3 from bottom to top, the opening of the collecting scraper bin 9 can scrape and clean the inner wall of the sealing bin 3, and the dust scraped off can fall into the collecting scraper bin 9 for collection.

[0031] Both the sealed cover 8 and the collecting scraper bin 9 have receiving grooves 13 on one side. Inside the receiving groove 13 is a limiting mechanism for fixing the filter plate 11. The limiting mechanism includes a limiting rod 14, which passes through one side of the receiving groove 13 and extends into the limiting slot 12. An external threaded ring 15 is installed on the outer side of the limiting rod 14 near the receiving groove 13. The central axis of the external threaded ring 15 coincides with the central axis of the limiting rod 14, and the two sets of external threaded rings 15 are respectively attached to the sealed cover. The filter plate 11 and the collection scraper bin 9 are threadedly connected, allowing the operator to move the filter plate 11 and the collection scraper bin 9 out of the sealed chamber 3 by using the closed cover 8. Then, the operator can further loosen the filter plate 11 by turning the limiting rod 14 and the external threaded ring 15 out of the corresponding limiting groove 12, thereby completing the disassembly task. At the same time, when the filter plate 11 is in the assembly state, the loosening direction of the limiting rod 14 is restricted by the sealed chamber 3, thus ensuring the stability of the filter plate 11 installation.

[0032] The working principle of this utility model is as follows: The device is powered by an external power source. When the main body 1 of the crushing rotary screen is in use, the exhaust fan 5 is turned on. As mentioned above, the exhaust fan 5 drives the air in the main body 1 of the crushing rotary screen and the dust cover 2 into the sealed chamber 3, and then re-enters the main body 1 of the crushing rotary screen and the dust cover 2 through the exhaust pipe 7 to form a circulating flow of air. During this process, the filter plate 11 can block and collect dust, thereby fully reducing the impact on the outside world.

[0033] When maintenance is required inside the sealed chamber 3, disconnect the connection between the sealing cover 8 and the sealed chamber 3, hold the sealing cover 8 and pull the filter plate 11 and the collecting scraper chamber 9 upwards. During this process, the collecting scraper chamber 9 can scrape and clean the inner wall of the sealed chamber 3 and collect all the dust attached to the inner wall of the sealed chamber 3 into the collecting scraper chamber 9. After the collecting scraper chamber 9 is completely removed from the sealed chamber 3, the limiting rod 14 and the external threaded ring 15 are turned away from the limiting groove 12 and the interior of the receiving groove 13 through the space reserved in the receiving groove 13, so that the sealing cover 8, the filter plate 11 and the collecting scraper chamber 9 are completely disassembled, which makes it easier for the staff to maintain and replace the filter plate 11 and to carry out subsequent treatment of the dust collected in the collecting scraper chamber 9.

[0034] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
