Description

Technical Field

[0001] This utility model relates to the field of calcium carbonate powder production technology, specifically a dust recovery device for a calcium carbonate powder production workshop. Background Technology

[0002] The production process of calcium carbonate powder generates a large amount of dust due to steps such as crushing, sieving, and packaging. This dust not only pollutes the working environment and affects workers' health, but also wastes raw materials and increases production costs. Therefore, installing effective dust recovery devices in the production workshop is crucial for improving the working environment, increasing raw material utilization, and ensuring safe production.

[0003] Traditional dust collection devices primarily rely on filtration or electrostatic adsorption to capture dust. However, considering that calcium carbonate powder is a material generated during the production process, conventional dust removal methods still require grading after collection. Furthermore, when filters become clogged, the system's dust collection efficiency drops significantly, necessitating shutdown for cleaning and maintenance. During maintenance periods, dust levels in the workshop cannot be effectively controlled. In addition, some traditional equipment lacks convenient dust collection and discharge designs, resulting in incomplete dust removal and a higher risk of secondary pollution. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a dust recovery device for a calcium carbonate powder production workshop, which solves the problem of difficult maintenance of conventional dust suppression systems, and realizes the graded recovery of calcium carbonate powder with different particle sizes.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a dust recovery device for a calcium carbonate powder production workshop, including a dust collection pipe, wherein a fan and a multi-mesh baffle are provided inside the dust collection pipe and between the fan and the inlet of the dust collection pipe, and the aperture of the multi-mesh baffle gradually decreases along the air flow direction inside the dust collection pipe.

[0006] A material collection hopper is provided on the side of the mesh partition near the inlet of the dust collection pipe. The material collection hopper is located at the bottom of the dust collection pipe, and a material collection tank is provided below the material collection hopper.

[0007] In a preferred embodiment, the inner top and bottom surfaces of the dust collection pipe are provided with multiple guide grooves, and the side walls of the dust collection pipe on both sides of the same vertical plane as the guide grooves are provided with openings. The mesh partition is installed through the openings, and the upper and lower sides of the mesh partition are provided with strip frames, which are located inside the guide grooves.

[0008] In a preferred embodiment, the length of the mesh partition is twice the width of the suction pipe.

[0009] In the preferred solution, the two ends of the net partition are provided with limiting plates with sizes larger than the sizes of the openings on the side walls of the dust suction pipeline.

[0010] In the preferred solution, the discharge opening at the bottom of the collecting hopper is circular, and a thread is arranged on the outer wall of the discharge opening, and the discharge opening is connected to the tank opening of the collecting tank through the thread.

[0011] In the preferred solution, the top of the dust suction pipeline is further provided with a main water pipe, the output end of the main water pipe is connected to a three-way valve, two branch water pipes are arranged on the three-way valve, the two branch water pipes extend to the two sides of the dust suction pipeline respectively, and cleaning nozzles are arranged on the branch water pipes and face the net partitions close to the branch water pipes.

[0012] The dust recovery device for calcium carbonate powder production workshop has the following beneficial effects by adopting the above structure:

[0013] (1) By arranging the multiple net partitions with gradually decreasing pore diameters, different particle size dusts can be effectively classified and captured, which not only improves the dust capture efficiency, but also reduces the possibility of fine particles penetrating the filter layer, and ensures a higher dust removal rate;

[0014] (2) The net partition is divided into left and right parts, when one part performs dust capture operation, the other part is naturally dried after water cleaning, which can avoid the vacuum period of dust removal operation caused by shutdown maintenance during regular maintenance and cleaning of the net partition;

[0015] (3) The design of the guide groove and the strip-shaped frame ensures the stability and position accuracy of the net partition during operation, reduces the risk of displacement of the net partition caused by vibration or other factors, and thus guarantees the long-term stable operation of the system.

[0023] like Figures 1-2 In a calcium carbonate powder production workshop, a dust collection device is provided, including a dust collection pipe 1. The dust collection pipe 1 is equipped with a fan 3 and a multi-mesh baffle 2 disposed between the fan 3 and the inlet of the dust collection pipe 1. The aperture of the multi-mesh baffle 2 gradually decreases along the air flow direction in the dust collection pipe 1.

[0024] A material collection hopper 4 is arranged on the side of the mesh partition 2 near the inlet of the dust collection pipe 1. The material collection hopper 4 is located at the bottom of the dust collection pipe 1, and a material collection tank 5 is provided below the material collection hopper 4.

[0025] In a preferred embodiment, the inner top and bottom surfaces of the dust collection pipe 1 are provided with multiple guide grooves 6. The side walls of the dust collection pipe 1 on the same vertical plane as the guide grooves 6 are provided with openings. The mesh partition 2 is installed through the openings, and the upper and lower sides of the mesh partition 2 are provided with strip frames 7, which are located inside the guide grooves 6.

[0026] In a preferred embodiment, the length of the mesh partition 2 is twice the width of the dust extraction pipe 1.

[0027] In a preferred embodiment, the mesh partition 2 is provided with limiting plates 8 at both ends, the size of which is larger than the opening size on the side wall of the dust extraction pipe 1.

[0028] In a preferred embodiment, the discharge port 9 at the bottom of the collecting hopper 4 is circular, and the outer wall of the discharge port 9 is provided with threads. The opening of the collecting tank 5 and the discharge port 9 are connected by threads.

[0029] In a preferred embodiment, the top of the vacuum pipe 1 is also provided with a main water pipe 10, the output end of the main water pipe 10 is connected to a three-way valve 12, the three-way valve 12 is provided with two branch water pipes 11, the two branch water pipes 11 extend to both sides of the vacuum pipe 1 respectively, and the branch water pipes 11 are provided with cleaning nozzles 13, which are set toward the nearby mesh partition 2.

[0030] The dust recovery device disclosed in this invention for a calcium carbonate powder production workshop, when performing dust recovery operations in the calcium carbonate powder production workshop:

[0031] First, select a suitable location within the workshop to install the dust extraction duct 1, ensuring its inlet is positioned above the work area where dust is most generated. Determine the length and routing of the dust extraction duct based on actual needs to cover as large a work area as possible.

[0032] A plurality of net partitions 2 are installed inside the dust suction pipe, maintaining a certain distance between each net partition. Starting from the side close to the inlet of the dust suction pipe, net partitions with gradually decreasing aperture are installed in sequence, ensuring that dust can be captured step by step according to particle size. At the same time, strip frames 7 are arranged on both sides of the net partitions, allowing them to slide into the pre-installed guide slots 6, ensuring that the net partitions are securely fixed in place.

[0033] A fan 3 is installed inside the dust suction pipe after the last net partition. The selection of the fan 3 should be based on the expected air flow and pressure loss, ensuring that it can provide sufficient suction to maintain efficient operation.

[0034] A collection hopper 4 is installed at the bottom of the dust suction pipe, with a corresponding collection tank 5 placed below. The discharge opening 9 at the bottom of the collection hopper is designed as a circle, with threads on the outer wall to facilitate secure connection with the tank opening through threads, achieving safe collection of dust.

[0035] Finally, a main water pipe 10 is installed at the top of the dust suction pipe, with two branch water pipes 11 connected through a three-way valve 12, extending to both sides of the dust suction pipe. Each branch water pipe 11 is equipped with a cleaning nozzle 13, which is directed towards the net partition 2 it is close to, used to flush the surface of the exposed part of the net partition 2.

[0036] In use:

[0037] Start the fan 3 to put the entire system into operation. At this time, the dust-containing air will flow along the dust suction pipe 1, and different particle sizes of dust will be intercepted when passing through multiple net partitions 2.

[0038] The dust settles to the collection hopper 4 under the action of gravity, then falls into the collection tank 5 for centralized collection.

[0039] When the net partition is found to be blocked or needs to be cleaned, the net partition 2 is pulled to move within the dust suction pipe 1, so that the clean net partition 2 is exposed and enters the dust suction pipe 1, while the blocked net partition 2 moves outside the dust suction pipe 1. By adjusting the three-way valve 12, the cleaning nozzle 13 on the cleaning mechanism is used to flush the net partition. The fan 3 can continue to operate during the entire process without affecting the dust collection operation.

[0040] When the collection tank 5 is full, the thread connection on the discharge opening 9 can be rotated to easily remove it, pour out the collected dust, and then reinstall it back in place.
