Description

Technical Field

[0001] This application relates to the technical field of refractory production equipment, and in particular to a dust removal device for a refractory production line. Background Technology

[0002] When producing refractory materials, the raw materials need to be crushed and screened according to their particle size. The equipment used in the screening process is generally a multi-layer vibrating screen. In the existing technology, the receiving bucket or hopper is usually set directly below the outlet of the vibrating screen. In this way, when the vibrating screen is working, the material discharged from the outlet of the vibrating screen can fall directly into the receiving bucket. However, this receiving method generates a lot of dust. Utility Model Content

[0003] To address the shortcomings of existing technologies, this application provides a dust removal device for a refractory production line. In this embodiment, a flexible connecting pipe and a flexible collecting bag are used to seal the open area between the material hopper and the discharge port of the vibrating screen. This allows the material to directly enter the sealed flexible connecting pipe after leaving the discharge port, reducing the amount of screened powdery material that escapes to the surrounding area and alleviating dust pollution.

[0004] The above-mentioned objective of this application is achieved through the following technical solution: A dust removal device for a refractory production line includes a fixed connecting ring, a movable connecting ring, and a flexible connecting pipe; The fixed connecting ring is used to fit around the discharge port of the vibrating screen. A connector for connecting to the discharge port of the vibrating screen is installed on the fixed connecting ring. The two ends of the flexible connecting tube are connected to the fixed connecting ring and the movable connecting ring respectively. The end of the flexible connecting tube away from the fixed connecting ring is fixed to the inside of the movable connecting ring. The movable connecting ring has two through slots, and two clamping rods are hinged to the movable connecting ring. The two clamping rods can move in the two through slots respectively. The end of the movable connecting ring away from the flexible connecting tube is movably connected to a drawstring bag. The drawstring bag is open at both ends and hollow inside. The diameter of the drawstring bag gradually increases in the direction away from the movable connecting ring. The end of the drawstring bag away from the movable connecting ring has a drawstring to control the diameter of the drawstring bag opening.

[0005] Optionally, one end of the pocket can be detachably connected to the inside of the movable connecting ring via a support ring.

[0006] Optionally, an elastic cord is provided at the end of the drawstring away from the drawstring. When the drawstring is opened by the support ring, the elastic cord is in a stretched and deformed state.

[0007] Optionally, both the fixed connecting ring and the movable connecting ring are provided with connectors, and the fixed connecting ring and the movable connecting ring can be connected by the connectors.

[0008] Optionally, the end of the flexible connecting pipe closest to the fixed connecting ring is fixedly connected to the fixed connecting ring via a connecting flange.

[0009] Optionally, the flexible connecting pipe includes a temporary storage section and a discharge section. When the flexible connecting pipe is fully extended, the diameter of the temporary storage section is larger than the diameter of the discharge section. The temporary storage section and the discharge section of the flexible connecting pipe are connected to the fixed connecting ring and the movable connecting ring, respectively.

[0010] Optionally, the diameter of the temporary storage section of the flexible connecting tube gradually decreases in the direction away from the fixed connecting ring.

[0011] In summary, this application has the following beneficial technical effects: This embodiment of the application uses a flexible connecting pipe and a flexible collecting bag to seal the open area between the material bucket and the discharge port of the vibrating screen, so that the material directly enters the sealed flexible connecting pipe after leaving the discharge port, reducing the amount of screened powdery material that escapes to the surrounding area and alleviating dust pollution.

[0014] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0015] This application provides a dust removal device for a refractory production line, used to reduce dust at the outlet of a vibrating screen, which includes a fixed connecting ring 10, a movable connecting ring 20, and a flexible connecting pipe 30. The flexible connecting pipe 30 is used for material to pass through. The two ends of the flexible connecting pipe 30 are connected to the fixed connecting ring 10 and the movable connecting ring 20 respectively. The fixed connecting ring 10 is used to loop around the discharge port of the vibrating screen. A connector 11 for connecting to the discharge port of the vibrating screen is installed on the fixed connecting ring 10. The end of the flexible connecting pipe 30 away from the fixed connecting ring 10 is fixed to the inner side of the movable connecting ring 20. The movable connecting ring 20 has two through slots 21, and two clamping rods 22 are hinged to the movable connecting ring 20. The two clamping rods 22 can move in the two through slots 21 respectively. The end of the movable connecting ring 20 away from the flexible connecting tube 30 is movably connected to a drawstring bag 40. The drawstring bag 40 is open at both ends and hollow inside. The diameter of the drawstring bag 40 gradually increases in the direction away from the movable connecting ring 20. The end of the drawstring bag 40 away from the movable connecting ring 20 has a drawstring rope 41 for controlling the opening diameter of the drawstring bag 40.

[0016] The following section will provide further details based on specific usage scenarios.

[0017] During use, the operator connects the fixed connecting ring 10 to the discharge port of the vibrating screen via the connector 11 on the fixed connecting ring 10. The connector 11 can be a fixed flange, pipe clamp, or other connecting tool. After connection, the fixed connecting ring 10 remains relatively fixed to the discharge port of the vibrating screen during operation. Then, the operator opens the receiving bag 40 on the movable connecting ring 20 and covers it over the receiving bucket. Next, the operator uses the closing rope 41 to tighten the discharge port of the receiving bag 40, ensuring the receiving bag 40 is tightly fitted onto the receiving bucket. After that, the operator can turn on the vibrating screen to start screening. The screened material enters the receiving bucket through the flexible connecting pipe 30 and the receiving bag 40. There is no opening between the receiving bucket and the discharge port of the vibrating screen, which greatly reduces dust pollution.

[0018] In summary, the embodiments of this application use a flexible connecting pipe 30 and a flexible collecting bag 40 to seal the open area between the material bucket and the discharge port of the vibrating screen, so that the material directly enters the sealed flexible connecting pipe 30 after leaving the discharge port, reducing the amount of screened powdery material that escapes to the surrounding area and alleviating dust pollution.

[0019] In addition, in this embodiment, two clamping rods 22 are provided on the movable connecting ring 20. The two clamping rods 22 can move on the through groove 21 of the movable connecting ring 20. Since the flexible connecting tube 30 is movably connected to the inner side of the movable connecting ring 20, the two clamping rods 22 can clamp the flexible connecting tube 30, so that the part of the flexible connecting tube 30 inside the movable connecting ring 20 is clamped and sealed. At this time, the operator can remove the receiving bucket filled with material, which alleviates the situation of dust scattering during the removal of the receiving bucket. The flexible connecting tube 30 can be a flexible soft connection, a soft cloth bag, etc. The movable connecting ring 20 can ensure that the flexible connecting tube 30 is opened to avoid material accumulation. At the same time, the flexible connecting tube 30 can also provide a basis for the installation of the bag 40. The end of the flexible connecting tube 30 near the fixed connecting ring 10 is fixedly connected to the fixed connecting ring 10 through a connecting flange.

[0020] In this embodiment, the receiving bag 40 is movably connected to the movable connecting ring 20. One end of the receiving bag 40 is detachably connected to the inside of the movable connecting ring 20 via the support ring 23. In this way, after the receiving bucket is filled with material, the operator can quickly remove the receiving bag 40 by pulling it, thereby maintaining the relatively closed state of the top opening of the receiving bucket and alleviating the situation of dust scattering. Based on this, an elastic rope 42 is provided at the end of the collection bag 40 away from the closing rope 41. When the collection bag 40 is opened by the support ring 23, the elastic rope 42 is in a stretched and deformed state. In this way, when the operator pulls the collection bag 40 to quickly remove the collection bag 40, the elastic rope 42 in the stretched and deformed state can restore its deformation and make the collection bag 40 quickly tighten, thereby maintaining the relatively closed state of the top opening of the receiving bucket and alleviating the situation of dust scattering. In this embodiment, both the fixed connecting ring 10 and the movable connecting ring 20 are provided with connectors, and the fixed connecting ring 10 and the movable connecting ring 20 can be connected by the connectors. Meanwhile, the flexible connecting tube 30 includes a temporary storage section 43 and a discharge section 44. When the flexible connecting tube 30 is fully extended, the diameter of the temporary storage section 43 of the flexible connecting tube 30 is larger than the diameter of the discharge section 44. The temporary storage section 43 and the discharge section 44 of the flexible connecting tube 30 are respectively connected to the fixed connecting ring 10 and the movable connecting ring 20.

[0021] In this way, when the receiving bucket is removed, the operator can simply attach the movable connecting ring 20 to the fixed connecting ring 10 without stopping the vibrating screen. The screened material can be temporarily stored in the temporary storage section 43 of the flexible connecting pipe 30, which improves the screening efficiency. The diameter of the temporary storage section 43 of the flexible connecting pipe 30 gradually decreases in the direction away from the fixed connecting ring 10, so that the material leaves the vibrating screen without obstruction when there is no receiving bucket.

[0022] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
