Abstract
Description
Technical Field
[0001] The utility model relates to the field of dust removal devices, in particular to a dust removal device. Background Art
[0002] In the production of ductile iron pipes, the centrifuge is a key piece of equipment used for casting and molding the pipes. However, during operation, the centrifuge generates a certain amount of dust. This dust primarily originates from the pouring of molten iron, the rotation of the mold, and tiny particles generated during the cooling process. To minimize the impact of centrifuge dust on the production environment and product quality, a dust removal device is typically used to remove dust from the centrifuge.
[0003] The centrifuge includes a socket. Existing dust removal devices connect a dust removal trolley to the socket through a pipe. The dust removal trolley's belt and dust collection box form a sealed space, and the main dust collection duct draws dust away from the sealed space. However, the belt-type dust removal trolley has poor sealing, which can lead to large dust removal air volume loss and poor dust removal results. Furthermore, after a period of use, the dust removal trolley can experience inconsistent wear on the main machine's track wheels and the trolley's wheels, which can easily cause stress on the trolley and destabilize the centrifuge. Furthermore, the trolley must move with the main machine, making frequent travel and resulting in a high failure rate. Furthermore, its location makes it difficult to maintain, resulting in high equipment and labor costs for maintaining this equipment. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.
[0021] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.
[0022] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.
[0023] In the production of ductile iron pipes, the centrifuge is a key piece of equipment used for casting and molding the pipes. However, during operation, the centrifuge generates a certain amount of dust. This dust primarily originates from the pouring of molten iron, the rotation of the mold, and tiny particles generated during the cooling process. To minimize the impact of centrifuge dust on the production environment and product quality, a dust removal device is typically used to remove dust from the centrifuge.
[0024] The centrifuge includes a socket. Existing dust removal devices connect a dust removal trolley to the socket through a pipe. The dust removal trolley's belt and dust collection box form a sealed space, and the main dust collection duct draws dust away from the sealed space. However, the belt-type dust removal trolley has poor sealing, which can lead to large dust removal air volume loss and poor dust removal results. Furthermore, after a period of use, the dust removal trolley can experience inconsistent wear on the main machine's track wheels and the trolley's wheels, which can easily cause stress on the trolley and destabilize the centrifuge. Furthermore, the trolley must move with the main machine, making frequent travel and resulting in a high failure rate. Furthermore, its location makes it difficult to maintain, resulting in high equipment and labor costs for maintaining this equipment.
[0025] The utility model provides a dust removal device, such as Figures 1 to 4 As shown, it includes a dust removal hood 14 and a dust removal pipe group 2. The dust removal pipe group 2 includes a fixed pipe 21, a hose 22, a main dust removal pipe 23, and a rotary joint 24. The fixed pipe 21 is fixedly connected to the dust removal hood 14. The rotary joint 24 includes two groups. Both ends of the hose 22 are respectively connected to the fixed pipe 21 and the main dust removal pipe 23 through the two groups of rotary joints 24.
[0026] It should be noted that the centrifuge 1 includes a bell end 12 and a socket end 13, and the dust cover 14 covers the bell end 12 and the socket end 13. When the centrifuge 1 is working, the dust-laden gas enters the main dust removal pipe 23 through the fixed pipe 21 and the hose 22. The main dust removal pipe 23 is connected to the next process processing device to realize dust collection and processing.
[0027] In this embodiment, the dust removal pipe group 2 is composed of a fixed pipe 21, a hose 22, a main dust removal pipe 23 and a rotary joint 24. These components work together to transport the dust-laden gas from the centrifuge 1 to the designated dust removal area. In this embodiment, the hose 22 has a certain flexibility and can adapt to bending and movement in different directions. The rotary joint 24 is a key component connecting the fixed pipe 21, the hose 22 and the main dust removal pipe 23. It has a rotation function and can adapt to the movement or rotation of the equipment in different directions while maintaining the continuity of the gas flow. The hose 22 and the rotary joint 24 work together to realize the mobile dust removal of the device, that is, when the centrifuge 1 moves, the hose 22 can swing with the body. The structure is simple, the failure rate is low, and it is easy to maintain. It can also reduce the loss of dust suction air volume and enhance the dust removal effect.
[0028] It should be noted that the rotary joint 24 is an existing technology, so that the connections between the two ends of the hose 22 and the fixed pipe 21 and the main dust removal pipe 23 are rotatable connections. Those skilled in the art should be clear about its structure, principle and usage method, etc., and no detailed description is given here.
[0029] In this embodiment, the fixed tube 21 and the hose 22 each include two groups, and the two groups of fixed tubes 21 are fixedly installed on the dust removal hood 14. The two groups of fixed tubes 21 correspond one-to-one to the socket end 12 and the plug end 13, respectively, ensuring that each port has an independent dust removal channel, which can effectively improve the dust removal efficiency.
[0030] In this embodiment, the main dust removal pipe 23 includes a fixed portion 231 and a connecting portion 232. The fixed portion 231 and the connecting portion 232 are fixedly connected and communicate with each other. The connecting portion 232 includes two groups, and the two groups of connecting portions 232 are respectively connected to the two groups of hoses 22 through a rotary joint 24. In this embodiment, the connecting portion 232 is configured as an inverted U-shaped structure.
[0031] In this embodiment, the fixed tube 21 includes a fixed section 211 and a connecting section 212. The two ends of the fixed section 211 are fixedly connected to the dust cover 14 and the connecting section 212 respectively and are interconnected. The connecting section 212 is configured as an inverted U-shaped structure. In the horizontal direction, the height of the connecting section 212 is consistent with the height of the connecting portion 232. In the horizontal direction, the heights of the two sets of rotary joints 24 are consistent. The height consistency helps to maintain the balance of the gas flow and avoid excessive resistance or vortexes at the connection.
[0032] In this embodiment, the hose 22 is hoisted in a U-shape, which helps to reduce the pressure loss of the gas in the fixed pipe 21 and improve the dust removal efficiency.
[0033] In this embodiment, the dust removal pipe groups 2 are symmetrically distributed along the vertical center axis of the centrifuge 1 .
[0034] The present invention provides a dust removal device, which is primarily suitable for dust removal in a mobile centrifuge 1 with a fixed main dust removal pipe 23. The flexible hose 22 can swing with the centrifuge 1, achieving mobile dust removal. The device connects the centrifuge 1 and the main dust removal pipe 23 via the flexible hose 22 and a rotary joint 24, achieving mobile dust removal. The device features a simple structure, a low failure rate, and easy maintenance. It also reduces dust collection air volume loss and enhances dust removal effectiveness.
