Description

Technical Field

[0001] The utility model relates to the technical field of dust removal and ash discharge valves, and in particular to a high-sealing double-layer ash discharge valve. Background Art

[0002] Dust removal and ash discharge valve is the main equipment for dust removal equipment to discharge dust, supply air and feed other equipment. Because some factories usually discharge harmful dust in a unified way, this leads to harmful dust consisting of dust with different particle sizes. When discharging this type of dust, it is necessary to classify the dust according to the particle size for subsequent processing, which requires the use of a high-sealing double-layer ash discharge valve.

[0003] Patent document CN217977386U discloses a highly sealed double-layer ash unloading valve, "including a valve body and a drive assembly, with the beneficial effects of: by adding a limit assembly to the existing ash unloading valve, the compression displacement of the bellows is limited when the valve is opened under the drive of a pneumatic device, thereby protecting the bellows from damage due to over-limit compression; by sealing and squeezing with the valve disc, the valve middle cavity is closed when opened, and the valve middle cavity cannot enter during ash unloading, thereby ensuring that the valve stem, stuffing box, etc. are not in contact with debris to avoid being blocked, thereby ensuring smooth opening and closing of the valve."

[0004] The above-mentioned equipment seals the valve cavity when opened through sealing and squeezing with the valve disc, and cannot enter the valve cavity when unloading dust, ensuring that the valve stem, stuffing box, etc. do not contact with debris to avoid being blocked, thereby ensuring the smooth opening and closing of the valve. It is inevitable that some dust harmful to the human body is generated during production in some processing plants, and some factories usually discharge harmful dust in a unified manner, which results in harmful dust consisting of dust of various particle sizes. When the equipment is unloading dust, dust of different particles are mixed with each other, which makes it difficult to effectively treat the dust according to the type of dust in subsequent work, which requires staff to improve their equipment. Utility Model Content

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the problem that a high-sealing double-layer ash unloading valve in the prior art is difficult to screen harmful dust, thereby providing a high-sealing double-layer ash unloading valve.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] include:

[0008] A storage box, wherein four groups of slide grooves are provided at the bottom of the inner wall of the storage box, two groups of the slide grooves are slidably connected to the first slide rail, a first mounting frame is provided on one side of the first slide rail, and the surface of the first mounting frame is slidably connected to the inner wall of the storage box, a coarse screen is provided on the inner wall of the first mounting frame, the inner walls of the two groups of the slide grooves are slidably connected to the second slide rail, a second mounting frame is provided on one side of the second slide rail, and a fine screen is provided on the inner wall of the second mounting frame.

[0009] As an optional technical solution, first thread grooves are provided on both sides of the inner wall of the storage box, and a sealing gasket is provided on the inner wall of the storage box.

[0010] As an optional technical solution, a servo motor is provided on one side of the storage box, a rotating shaft is provided at the output end of the servo motor, and both ends of the rotating shaft are rotatably connected to the inner wall of the storage box.

[0011] As an optional technical solution, a connecting plate is provided on the surface of the rotating shaft, and one side of the connecting plate is overlapped with the inner wall of the storage box.

[0012] As an optional technical solution, a protection box is provided on one side of the storage box, and a heat dissipation net is provided on one side of the protection box.

[0013] As an optional technical solution, a guide cylinder is provided at the bottom of the storage box, a connecting tube is provided at the top of the storage box, and a feed tube is overlapped on the surface of the connecting tube.

[0014] As an optional technical solution, a clamping plate is provided at the top end of the connecting pipe, a second thread groove is opened on the surface of the clamping plate, and the surface of the feed pipe is overlapped with the inner wall of the clamping plate, and a ring is threadedly connected to the surface of the clamping plate.

[0015] As an optional technical solution, a sealing ring is provided on the surface of the connecting pipe, and the inner wall of the feeding pipe overlaps the surface of the sealing ring.

[0016] The utility model technical solution has the following advantages:

[0017] 1. The utility model screens the discharged harmful dust through two sets of screens, and divides multiple sets of harmful dust into two parts according to the size of the particles, so that the subsequent staff can handle the harmful dust with different particles. The setting of the two sets of screens can avoid the situation where too much dust accumulates on the surface of a single screen when there is too much dust, which makes it difficult for the screen to quickly discharge the dust, thereby causing the screen to be blocked. The screen can be taken out from the bottom of the storage box through the slide rails on both sides of the installation frame, which is convenient for cleaning the surface of the screen to maintain the screening efficiency of the screen.

[0018] 2. The utility model removes the bolts on both sides of the storage box from the first threaded groove, thereby splitting the storage box into two groups, so that it is convenient for the staff to clean the inside of the equipment to prevent dust from adhering to the inner wall of the equipment and affecting the normal operation of the equipment. After cleaning, the two groups of storage boxes can be installed using bolts through the first threaded groove. After installation, the sealing gasket in the storage box can fill the gap between the storage boxes to form a closed space inside the storage box, effectively preventing dust leakage.
