Abstract
Description
Technical Field
[0001] This utility model relates to the field of transportation equipment technology, and more specifically, to a dustproof conveying device. Background Technology
[0002] Dust control transport devices are equipment or systems used to reduce or eliminate dust during material transportation. They are mainly used in industries such as industry, mining, and medicine, aiming to improve the working environment, protect personnel health, and improve transportation efficiency.
[0003] Existing dust-proof transportation systems have long faced a major challenge in addressing the dust generated during material transport. Dust not only severely pollutes the production environment and harms employee health, but also increases equipment wear and maintenance costs, reduces production efficiency, and in extreme cases, can even cause fires or explosions, posing a serious threat to safe production.
[0004] Therefore, we have made improvements to this and proposed a dustproof conveying device. Utility Model Content
[0005] The purpose of this invention is to address the long-standing problem of dust generation during material transport in existing dust-proof transport devices, which has been a major challenge for many enterprises. Dust not only severely pollutes the production environment and harms the health of employees, but also increases equipment wear and maintenance costs, reduces production efficiency, and in some extreme cases, may even cause fires or explosions, posing a serious threat to the safe production of enterprises.
[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0007] Dustproof conveying devices are used to improve the above-mentioned problems.
[0008] The application is as follows:
[0009] Includes: a V-shaped air duct; a ventilation frame installed inside the V-shaped air duct; a fixing block installed on one side of the ventilation frame; a snap-fit device installed inside the fixing block; and a filter screen that slides inside the ventilation frame. The snap-fit device includes two snap rods that slide inside the fixing block. A fixing plate is installed on the surface of the snap rods. An adapter groove is provided inside the fixing block. The filter screen slides inside the fixing block through the adapter groove. A spring is installed inside the adapter groove. The end of the spring near the fixing plate is fixedly connected to the fixing plate.
[0010] To achieve the above technical solution, when the U-shaped rod moves to a position where it is no longer in contact with the fixed plate, the locking rod moves under the action of spring one. Once the locking rod is inside the slot, it limits the movement of the filter screen. When the filter screen needs to be removed, the operator pulls the locking rod, causing it to move out of the slot and releasing the filter screen from its position. The movement of the locking rod causes the fixed plate to move. When the fixed plate reaches the top of the U-shaped rod, the U-shaped rod moves under the action of spring two. When the U-shaped rod reaches the bottom of the fixed plate, it limits the movement of the fixed plate and resets the locking rod. At this point, the operator moves the filter screen out of the ventilation frame, completing the removal of the filter screen.
[0011] As a preferred embodiment of the dustproof conveying device provided by this utility model, the ventilation frame has a ventilation slot inside, and a dust-collecting fan is installed inside the ventilation slot.
[0012] To achieve the above technical solution, a dust-collecting fan is installed so that the dust-laden air inside the V-shaped air duct enters the interior of the ventilation frame through the ventilation slot.
[0013] In a preferred embodiment of the dustproof conveying device provided by this utility model, the clamp rod is fixedly connected to the filter screen through a clamp groove.
[0014] To achieve the above technical solution, a locking rod is set up. When the locking rod moves into the slot, the filter screen can be limited.
[0015] As a preferred embodiment of the dustproof conveying device provided by this utility model, a limiting block is installed inside the adapter groove, a push rod is slidably fitted inside the limiting block, a U-shaped rod is installed at one end of the push rod, and a spring is installed between the limiting block and the U-shaped rod.
[0016] To achieve the above technical solution, a push rod is set up so that the U-shaped rod moves when the filter screen pushes the push rod to move.
[0017] As a preferred embodiment of the dustproof conveying device provided by this utility model, the ventilation frame has multiple ventilation holes inside.
[0018] To achieve the above technical solution, by setting up ventilation holes, the air that has been filtered inside the ventilation frame can be discharged from the inside of the ventilation holes.
[0019] In a preferred embodiment of the dustproof conveying device provided by this utility model, one end of the U-shaped rod is in contact with the fixed plate.
[0020] To achieve the above technical solution, when the U-shaped rod moves to a position where it no longer contacts the fixed plate, the locking rod moves under the action of the spring.
[0021] In a preferred embodiment of the dustproof conveying device provided by this utility model, a pull block is installed on one side of the filter screen.
[0022] To achieve the above technical solution, a pull block is installed to facilitate the removal of the filter screen from inside the ventilation rack by the staff.
[0023] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a V-shaped air duct, dust generated inside the transport equipment can be discharged from the inside of the V-shaped air duct and the ventilation frame to the outside of the equipment. By setting a filter screen, the air containing dust can be filtered, thereby reducing the dust content in the discharged air. When the filter screen is used for a long time, the filtration effect of the filter screen deteriorates and it needs to be replaced. The filter screen can be disassembled or installed through a snap-fit device, which facilitates the cleaning of the filter screen. Attached Figure Description
