In this application, dust collector is responsible for through the dust absorption and is connected with the suction hood, and the suction hood cover is established on manganese dioxide closed milling equipment's raise dust point. Because the dust collector produces the negative pressure in the suction hood, the dust is sucked into dust collector after coming out from the dust raising point of the closed manganese dioxide powder grinding device. It should be noted that the annular dust hood main body and the device are connected in a gap, and the assembled movable dust hood is also connected with the ground platform in a gap. And opening the dust removal device, and allowing the air outside the gap to enter the dust hood under the action of air pressure. The air inlet amount of the gap is small, so that the interior of the dust hood is always kept at a micro negative pressure, namely, air flow at the gap enters the inner side of the dust hood from the outer side of the dust hood. Thereby prevent that the dust from going out from the gap between suction hood and device or the ground platform, so that this coarse fodder storehouse dust adsorption system can the effectual dust volume that reduces equipment place space.

In the application, the manganese dioxide raw material is filtered and recovered under the action of a dust removal device. Through the primary screening device on the dust absorption main pipe, large-particle manganese dioxide fragments in the dust airflow can be screened out in advance. And large-particle manganese dioxide fragments are recovered, and the dust removal pressure of the dust removal device is reduced. The dust removal efficiency and the long-time dust removal capability of the dust removal device are improved. Thereby improving the work efficiency of the dust adsorption system applied to the milling system of the Raymond mill and reducing the production cost.

It should be noted that, in the prior art, manganese dioxide is pulverized and recovered in a closed manganese dioxide powder grinding device. However, dust generated by the pulverization is manganese dioxide, and the dust is scattered to a production workshop at will, so that the pollution and the waste of the manganese dioxide are caused greatly. Therefore, a dust removing device is needed to collect the benne dioxide dust. As manganese dioxide is crushed, dust and large manganese dioxide fragments are generated. Most of large-particle manganese dioxide fragments fall into a storage bin of the closed manganese dioxide grinding device under the action of gravity. But because of the action of the dust removing device, large negative pressure can be generated in the dust hood. Under the action of large negative pressure, the dust airflow will reach a certain speed. Under the action of the dust airflow, a small part of large manganese dioxide fragments enter the dust absorption branch pipe along with the dust airflow, are gathered to the main dust absorption pipe, and finally all enter the dust removal device. The large-particle manganese dioxide fragments are large in size, so that an airflow pipeline of the dust removal device is easily blocked, the adsorption force of the dust removal device is reduced, and the dust removal effect is influenced. In order to meet the requirement of dust removal effect, the whole production system must be stopped frequently, large-particle manganese dioxide fragments in the dust removal device are cleaned, and therefore production efficiency is affected. In addition, because large-particle manganese dioxide fragments have sharp shapes, the overall hardness is high. Easily cause wearing and tearing to dust collector, reduce dust collector's life. It is therefore necessary to remove the large particulate manganese dioxide fragments in advance of the dust stream entering the dust removal apparatus.

In an embodiment of the prescreening device of the present invention, the prescreening device comprises: a dust stopping structure and a stopping installation mechanism. The dust stopping structure is arranged on the main dust collecting pipe through a stopping installation mechanism. The dust stopping structure is vertical to the flowing direction of dust airflow in the dust absorption main pipe. When dust gas in the dust collection main pipe passes through the dust stopping structure, the flow path of the dust gas is nonlinear. When the dust gas enters the dust stopping structure and the dust gas is discharged from the dust stopping structure, the flowing directions of the gas are consistent. However, the dust stopping structure can change the gas flowing direction in the dust stopping structure and then change the gas flowing direction back to the original flowing direction. This change causes large manganese dioxide fragments in the dust gas to strike the dust-stopping structure and then to move horizontally at a zero or negative velocity, thereby falling into or downstream of the dust-stopping structure. Thereby preventing large-particle manganese dioxide fragments from entering the dust removal device. Thereby prolonging the service life of the dust removing device and improving the dust removing effect.

In the application, the mounting frame of the interception mounting mechanism is arranged on the inner wall of the main dust suction pipe. An opening is formed in one end of the mounting frame, and a dust stopping structure is conveniently placed in the mounting frame.

In this application, the inboard of installing frame is equipped with inboard mounting groove, and inboard mounting groove is connected with the outside edge of dust interception structure. Or the outer side of the dust stopping structure is provided with an outer side mounting groove, and the inner side edge of the mounting frame is connected with the outer side mounting groove. The dust stopping structure and the stopping installation mechanism can be installed quickly and tightly.

In this application, the prescreening device still includes: baffle locking structure. The dust stopping structure is used for resisting dust so that the dust stopping structure is not easy to separate from the stopping installation structure.

In the present application, the outer frame of the dust intercepting structure is connected to the intercepting-mounting mechanism. The fluid perturbation structure is mounted on the outer frame.

In the present application, the fluid interference structure is specifically a mesh structure, and the dust airflow passing through the fluid interference structure of the mesh structure can generate turbulent flow, so that the dust airflow direction is not consistent with the movement direction of large-particle manganese dioxide fragments. Large-particle manganese dioxide fragments fall to a lower pipe arm of the main dust absorption pipe under the action of gravity without being supported by stable airflow.

In another embodiment of the fluid disturbance structure of the present application, a baffle plate, a catch tank, is disposed at an upper end of the outer frame. The material intercepting groove is arranged at the lower end of the outer frame and is positioned below the flow baffle. The flow baffle and the material intercepting groove form a bent air channel, so that when dust airflow passes through the dust intercepting structure, large-particle manganese dioxide fragments collide with the flow baffle, and the large-particle manganese dioxide fragments fall into the material intercepting groove. Thereby playing the role of stopping large-particle manganese dioxide fragments.

In the present application, the lower edge of the baffle plate is below the plane of the upper opening of the cutoff channel so that large manganese dioxide fragments must impinge on the baffle plate. The interception effect of the primary screening device on large-particle manganese dioxide fragments is improved.

In this application, the dust absorption cover forms the dust absorption cavity with manganese dioxide closed milling equipment's outer wall, plays fine dust absorption effect to the raise dust of overflowing from the raise dust point.

It should be noted that the coarse material bin of the closed manganese dioxide milling device adopts an annular dust hood, so that the coarse material bin keeps a slight negative pressure in the feeding process, and no dust is dissipated in the whole feeding process.

Because the condition of the micro-positive pressure operation of the closed type Raymond mill system happens occasionally, the dust raising points near the main machine of the Raymond mill are more and dispersed. The dust hood through this scheme design is for assembling movable annular dust hood, can be applicable to the many dust lifting points of collecting different positions of raymond mill host computer.

In this application, design out unique annular suction hood for coarse fodder storehouse for the coarse fodder storehouse keeps little negative pressure in feeding process, prevents the dust loss.

In this application, the suction hood is assembled by 4 nonmetal arc adjustable baffles that light in weight and forms, and the dust absorption mouth is established in the bottom. Simple and fast, and is convenient to disassemble, assemble and use.

In this application, all install electrical control valve on every dust absorption branch pipe, be connected with equipment control system. The electric valve of the collecting pipeline can be automatically opened when the equipment runs, and dust of the equipment can be absorbed. When the equipment does not operate, the electric regulating valve is closed, and the negative pressure formed by the dust removing device is reduced.

In this application, dust collector adopts inverter motor, and dust collector and pressure transmitter are correlated with each other, are responsible for the operating frequency of pressure automatically regulated draught fan according to the dust absorption, adjust whole negative pressure, play the purpose of power saving.

In this application, every dust absorption branch pipe all adopts 45 degrees angles upwards to insert the dust absorption and is responsible for. Preventing dust from being accumulated at the dust absorption branch pipe.

In this application, among the whole coarse fodder storehouse dust adsorption system, all adopt stainless steel or nonmetal with the material of the structure of material contact part, prevent promptly that equipment from rustting, ageing.
