Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a dust removal device for calcium carbonate production. Background Art

[0002] Calcium carbonate, as an important non-metallic mineral basic raw material in daily industrial production, is at the forefront of the industrial chain and is known as "industrial food". It is closely related to the national economy and life and is an important supporting material for the development of emerging industries and high-tech.

[0003] During the production process of calcium carbonate, a large amount of calcium carbonate dust will be generated and diffused into the air, which will not only cause environmental pollution but also affect people's health, so dust removal devices are usually needed. However, after long-term use of existing dust removal devices, the filter screen is very easy to be blocked, and it is necessary to stop work frequently for maintenance, which increases maintenance costs and reduces production efficiency.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A dust removal device for calcium carbonate production includes a base and a filter box. The upper end of the base is provided with a filter box, the upper end of the filter box is provided with an upper cover, and the middle part of the upper cover is provided with an air inlet pipe connected with the filter box. A limit ring is provided on the inner wall of the filter box, and a filter assembly is movably installed in the limit ring. A support spring and a vibration motor are provided at the bottom of the filter assembly. The filter assembly includes a bracket, a filter cartridge and a bottom plate fixed in sequence from top to bottom. A vertical limit pin is provided on the limit ring. The limit pin movably passes through the edge of the bracket, and a compression spring is sleeved on the limit pin between the limit ring and the bracket. A connecting pipe is connected to the outer cavity of the filter cartridge, and an absorption box is connected to the end of the connecting pipe. The absorption liquid is contained in the absorption box.

[0007] Furthermore, the vibration motor is centrally arranged on the lower end surface of the bottom plate, and a dust cover is provided on the outer side of the vibration motor.

[0008] Furthermore, an exhaust fan is also provided on the connecting pipe.

[0009] Furthermore, the absorption liquid is clean water, which can absorb carbon dioxide gas in the tail gas and form carbonic acid, thereby reducing adverse effects on the atmospheric environment.

[0010] Furthermore, an exhaust pipe is inserted into the upper end of the absorption box.

[0011] Furthermore, the support spring is arranged vertically, the upper end of the support spring contacts the lower end surface of the bottom plate, and the lower end of the support spring contacts the bottom of the filter box.

[0012] The utility model also includes other components that enable the dust removal device for calcium carbonate production to be used normally, and these devices or components all adopt conventional technical means in the field. In addition, the devices and components not limited in the utility model all adopt conventional technical means in the field, such as the vibration motor in this application. In the specific implementation process, the appropriate device or component model can be selected according to the specific working scene.

[0013] The working principle of the utility model is: the tail gas produced by the production of calcium carbonate is introduced into the filter box from the air inlet pipe, and the vibration motor drives the filter assembly to vibrate up and down to peel off the micro calcium carbonate attached to the filter cartridge to prevent the filter cartridge from being blocked. After the micro calcium carbonate in the tail gas is filtered out, the tail gas is introduced into the absorption box along the connecting pipe for treatment, and the carbon dioxide gas in the tail gas is absorbed to reduce the adverse effects on the atmospheric environment.

[0014] Compared with the prior art, the utility model has the following beneficial effects: reducing filter cartridge blockage, reducing maintenance costs, and improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
