Description

Technical Field

[0001] The present application relates to the technical field of calcium hydroxide production, and specifically discloses a dust removal device for calcium hydroxide production. Background Art

[0002] Calcium hydroxide production equipment is a device for producing calcium hydroxide powder. Through the mining, transportation, crushing, multi-stage digestion, powder selection and packaging of raw materials, it finally produces high-purity calcium hydroxide products, which is what we commonly call lime powder. Calcium hydroxide is widely used. It is one of the very common and indispensable materials in our production and life such as construction manufacturing and road paving.

[0003] However, there are some unreasonable aspects in the existing calcium hydroxide production device. In the process of producing calcium hydroxide, due to the transportation and dumping of calcium hydroxide, a large amount of dust is likely to gush out from the silo, float in the air under the flow of air, and then fall back to the ground, which not only wastes a large amount of calcium hydroxide, but also pollutes the environment and causes innocent harm to the surrounding residents. The most terrible thing is that the workers near the production device are in a dusty environment for a long time, and a large amount of dust particles seriously affect the health of the workers and cause respiratory and lung diseases.

[0004] Most of the existing dust removal devices are large exhaust fans, which are installed on the top or both sides of the factory building, and the negative pressure difference generated by the exhaust fans is used to suck out the calcium hydroxide dust during production inside the factory building.

[0005] This mode can only play an overall control role, for example, keeping the overall dust level in the factory within a certain range. However, this device is not very effective for the local environment because the wind force of the large exhaust fan cannot reach it. In view of this, the inventor proposes a dust removal device for calcium hydroxide production. Utility Model Content

[0006] The utility model aims to solve the problem that the traditional dust removal device of the exhaust fan cannot act on the local dust generating position.

[0029] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0030] The figure marks in the drawings of the specification include: ceiling 1, air supply sleeve 2, support column 3, filter box 4, exhaust cylinder 5, dust cover 6, ventilation plate 7, main hole 8, secondary hole 9, exhaust pipe 10, mounting plate 11, motor 12, rotating shaft 13, winding cylinder 14, mounting block 15, cylinder 16, placement cover 17, rotating shaft 18.

[0031] Implementation example Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown:

[0032] A dust removal device for calcium hydroxide production, comprising a plurality of dust removal components mounted on a ceiling 1, wherein the number of dust removal components depends on the environment, such as the floor area of ​​a plant and the production volume of calcium hydroxide. If the floor area of ​​a plant is large, the number of dust removal components required will increase.

[0033] The dust removal assembly includes an exhaust cylinder 5, a filter box 4, an exhaust fan, a plurality of support columns 3 for providing support, and a dust removal cover 6 connected to the filter box 4;

[0034] Specific:

[0035] The exhaust fan is connected to the exhaust tube 5, the exhaust tube 5 is connected to the filter box 4, the support column 3 is installed on the filter box 4 and connected to the filter box 4, the other end of the filter box 4 is provided with an air supply sleeve 2, the air supply sleeve 2 passes through the ceiling 1 and is connected with the dust cover 6, the filter box 4 needs to be cleaned regularly because a filter net is provided in the filter box 4, the purpose of the filter net is to prevent calcium hydroxide dust from entering the exhaust fan, thereby affecting the life of the exhaust fan, the filter box 4 needs to be cleaned, and the corresponding ceiling 1 can be manually dismantled.

[0036] A ventilation plate 7 is detachably connected to the dust cover 6, and the ventilation plate 7 is provided with a main hole 8 and a plurality of auxiliary holes 9. Figure 2 As shown, the main hole 8 is a large-area hole, and the secondary hole 9 is a small-area hole. The large-area hole ensures the overall exhaust function, and the small-area hole is used because it acts on local exhaust. An exhaust pipe 10 is connected to the secondary hole 9, and a winding assembly for winding the exhaust pipe 10 is provided on the dust removal hood 6. A placement cover 17 is installed at the free end of the exhaust pipe 10.

[0037] The winding assembly includes a motor 12, a rotating shaft 13 coaxially connected to the output shaft of the motor 12, a winding drum 14 coaxially connected to the rotating shaft 13, a mounting plate 11 for mounting the motor 12, and an extrusion assembly arranged on the winding drum 14 plate for improving the efficiency of winding the exhaust pipe 10, wherein the mounting plate 11 is installed on the side wall of the dust cover 6.

[0038] When local exhaust is needed, a winding assembly is needed to release the exhaust pipe 10, thereby changing the position of the placement cover 17. In terms of connection: both ends of the exhaust pipe 10 are threaded sections, one end of the exhaust pipe 10 is threadedly connected to the secondary hole 9, and the other end of the exhaust pipe 10 is threadedly connected to the placement cover 17.

[0039] The extrusion assembly includes a mounting block 15 disposed on the winding drum 14 and a cylinder 16 mounted on the mounting block 15 . The extended end of the cylinder 16 can contact the air extraction pipe 10 and cause the air extraction pipe 10 to be extruded.

[0040] Specifically: Since there is a release of the exhaust pipe 10, there is a corresponding retraction of the exhaust pipe 10. In order to improve the efficiency of retraction, an extrusion assembly is designed. When retracting the pipe, the extended end of the cylinder 16 can contact the exhaust pipe 10 and squeeze the exhaust pipe 10 to provide an extrusion force to facilitate retraction of the pipe, thereby avoiding the problem that the exhaust pipe 10 cannot be quickly wound based on the rotation of the winding tube 14.

[0041] like Figure 5 As shown, the placement cover 17 includes a cover body and a rotating shaft 13 arranged on both sides of the bottom of the cover body. When the placement cover 17 is used, the rotating shaft 13 is used to realize the left rotation and right rotation of the placement cover 17, thereby completing the change of the exhaust direction of the placement cover 17.

[0042] The system further comprises a controller for controlling the power of the exhaust fan, the start and stop of the motor 12 and the start and stop of the cylinder 16 .

[0043] Specific implementation process:

[0044] Start the exhaust fan to complete the overall dust removal of the factory building, then start the motor 12, so that the exhaust pipe 10 can be manually extended downward, and the placement cover 17 can be manually brought to the area where local dust removal is required for local dust removal. After the dust removal is completed, start the cylinder 16, and use the extended end of the cylinder 16 to contact the exhaust pipe 10 and squeeze the exhaust pipe 10, providing an extrusion force to facilitate the collection of the pipe.

[0045] The device solves the problem that the traditional exhaust fan dust removal device cannot reach the local dust generating position.
