Description

Technical Field

[0001] The present invention relates to the technical field of dust removal equipment, and in particular to an environmentally friendly dust removal device for the production of slag fine powder and ready-mixed concrete. Background Art

[0002] Currently, the production of slag powder and ready-mixed concrete generates large quantities of fine powder and dust during the grinding, conveying, batching, mixing, and bagging stages. If this dust is not effectively collected and treated, it can reduce visibility in the workshop, worsen air quality, and impact operator health. It can also increase raw material loss, pollute the environment, and cause dust to accumulate on pipes, valves, and equipment near the production line, shortening their service life.

[0003] Existing dust removal devices mostly use filter bags as the main filter medium, using negative pressure fans to suck dust-laden gas through the filter bags for filtration before discharge or return. However, these filter bags often lack sufficient internal support structures. When high-volume and high-concentration dust is sucked, the filter bags tend to fold together, causing local blockage that significantly increases the pressure difference and affects the air outlet. In addition, most existing equipment relies solely on pulse jet backflushing for filter bag cleaning. However, single airflow cleaning can often only remove loose dust on the surface of the filter bags, making it difficult to meet the requirements of long-term low-maintenance operation. To solve the above problems, we propose an environmentally friendly dust removal device for slag micropowder and ready-mixed concrete production. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides an environmentally friendly dust removal device for the production of slag fine powder and ready-mixed concrete, which solves the problems raised in the background technology.

[0006] By adopting the above technical solution, a negative pressure fan is set up to extract air through the connecting pipe, and a long-term low-maintenance dust removal effect is achieved through the dust removal component.

[0010] By adopting the above technical solution and setting up an air pump, when the filter bag is loaded with dust and the pressure difference between the inside and outside reaches the set value, the air pump is started to introduce gas into each inner tube through the gas distribution pipe. At this time, the air flow is injected into the interior of the filter bag along the inner tube to remove the loose dust on the surface of the filter bag.

[0012] By adopting the above technical solution and setting up turbine blades, when high-pressure gas is ejected from the air distribution pipe, the airflow will drive the turbine blades to rotate at high speed, driving the reciprocating screw to rotate synchronously. The matching screw nut can realize the reciprocating movement of the hollow ring along the reciprocating screw, and then the hollow ring can cling to and scrape the inner wall of the filter bag, which can effectively supplement the insufficient effect of simple airflow cleaning.

[0020] By adopting the above technical solution, a baffle is set to cooperate with the inclined hole to guide the dust falling into the box to settle along the set path, avoiding secondary dust caused by air flow disturbance. At the same time, the recovery drawer set in the bottom frame is used to centrally collect the settled dust, thereby improving convenience and environmental protection.

[0021] In summary, the present invention mainly has the following beneficial effects: A negative pressure fan is set up to extract air through the connecting pipe, and a long-term low-maintenance dust removal effect is achieved through the dust removal component. A filter bag is set up to filter the air drawn in by the negative pressure fan, so that the dust is trapped on the outer surface of the filter bag, and the clean gas is discharged through the filter bag.

[0022] By setting up an air pump, when the filter bag is loaded with dust and the internal and external pressure difference reaches the set value, the air pump is started to introduce gas into each inner tube through the air distribution pipe. At this time, the air flow is injected into the interior of the filter bag along the inner tube to remove the loose dust on the surface of the filter bag. By setting up turbine blades, when the high-pressure gas is ejected from the air distribution pipe, the air flow will drive the turbine blades to rotate at high speed, driving the reciprocating screw to rotate synchronously. The matching screw nut can realize the reciprocating movement of the hollow ring along the reciprocating screw, and then the hollow ring can cling to and scrape the inner wall of the filter bag, which can effectively supplement the insufficient influence of simple airflow cleaning.

[0023] By setting up a spring tube, when the hollow ring moves up and down closely against the inner wall of the filter bag, high-pressure gas can enter the spring tube from the installation hole and be injected into the interior of the hollow ring, and then directly hit the inner wall of the filter bag through the nozzle, thereby achieving deep cleaning of the filter bag. By setting up a support ring, it is used to cooperate with the reciprocating screw rod to be installed inside the filter bag, thereby supporting the filter bag to prevent the filter bag from folding during vacuuming.

[0024] A limit rod is set to assist the hollow ring in stably moving up and down reciprocatingly to prevent it from affecting the cleaning operation as the reciprocating screw rotates. A baffle is set to cooperate with the inclined hole to guide the dust falling into the box to settle along the set path, avoiding secondary dust caused by air flow disturbance. At the same time, the recovery drawer set in the bottom frame is used to collect the settled dust in a centralized manner, thereby improving convenience and environmental protection.
