The system is characterized in that: the dust removal system for the main building of the concrete mixing plant further comprises an intermediate bin dust collector and a mixing unit dust collector; the intermediate bin dust collector is a forced dust collector installed inside the intermediate bin, maximizing the air inlet area of the forced dust collector and specifically responsible for handling dust generated during feeding of aggregates from the inclined belt conveyor and unloading of aggregates from the intermediate bin; the mixing unit dust collector is also a forced dust collector, installed and fixed above the mixing unit, and specifically responsible for handling dust generated when the intermediate bin unloads aggregates into the mixing unit, when the screw conveyor feeds powder into the powder metering hopper, and when the powder metering hopper unloads powder into the mixing unit; an air vent is provided on the top cover of the mixing unit, and an air vent is also provided on the top of the powder metering hopper, both of which are provided with needle-punched felt for filtering air. In the existing dust removal system of the mixing main building, the dust collector is an independent component and needs to occupy a certain space. In order to ensure the stable operation of the dust collector, an independent maintenance platform needs to be set up for it, which makes the entire mixing station main building occupy a large area; the mixing host needs to have independent connection ports with the intermediate warehouse, powder metering hopper, and dust collector. The space for the opening of the mixing host is limited, and the opening size for connecting the dust collector is small. The mixing host and the dust collector usually need to be connected with a connecting pipe. The use of the connecting pipe will cause a certain amount of wind loss and the connecting pipe is easy to clog, and the working efficiency of the dust collector is low. Summary of the Invention

DETAILED DESCRIPTION

[0019] The present invention is further described below through specific embodiments.

[0020] Reference Figures 1 to 3 As shown, a main building of a mixing station includes a mixing main unit 1, a transition bin 2, and a powder scale 3. The transition bin 2 and the powder scale 3 are arranged above the mixing main unit 1 and connected to the mixing main unit 1.

[0021] The transition bin 2 includes a bin body 21, a dust collector 22, and a first ventilation pipe 23. A connection port 24 is provided at the bottom of the bin body 21, which is sealed and connected to the mixing host 1 through the connection port 24; the bin body 21 includes a silo area 211 and a dust removal area 212, which are separated from each other. The upper part of the silo area 211 is provided with a transition bin feed port 2111, and the lower part is provided with a transition bin discharge port 2112. The transition bin discharge port 2112 is provided with a transition bin discharge door 2113. One end of the first ventilation pipe 23 is connected to the silo area 21 1 is sealed and connected to the upper part of the mixing host 1, and the other end is sealed and connected to the upper part of the mixing host 1; the dust removal area 212 is vertically arranged in the warehouse body 21, and the upper part of the dust removal area 212 is provided with an air outlet 2121 and the lower part is provided with an air inlet 2122. The dust collector 22 is arranged in the middle of the dust removal area 212 and divides the dust removal area 212. The air inlet 2122 and the air outlet 2121 are respectively located on the upper and lower sides of the dust collector 22. The air inlet 2122 and the transition bin discharge port 2112 constitute the connection port 24 of the warehouse body. The dust collector 22 is preferably a pulse bag dust collector.

[0022] The powder scale 3 includes a weighing bin 31, a powder scale feed port 32, a discharge pipe 33, a powder scale discharge door 34, and a second ventilation pipe 35. The powder scale feed port 32 is located at the upper part of the weighing bin 31. The weighing bin 31 is tightly connected to the mixing main unit 1 through the discharge pipe 33. The powder scale discharge door 34 is located between the weighing bin 31 and the discharge pipe 33 to open and close the connection between the weighing bin 31 and the discharge pipe 33. One end of the second ventilation pipe 35 is connected to the upper part of the weighing bin 31, and the other end is connected to the discharge pipe 33. The second ventilation pipe 35 can balance the pressure between the weighing bin 31 and the mixing main unit 1.

[0023] The connection between the first ventilation pipe 23 and the mixing main unit 1 and the connection between the discharge pipe 33 and the mixing main unit 1 are respectively located on both sides of the connection port 24 between the silo 21 and the mixing main unit 1. If the powder dust wants to reach the connection between the first ventilation pipe 23 and the mixing main unit 1, it must first pass through the connection port 24 of the transition bin 2. The powder dust will first be absorbed by the air inlet 2122 in the connection port 24, thereby preventing the powder dust from entering the first ventilation pipe 23.

[0024] The working principle of the main building of this concrete mixing station is as follows:

[0025] Feeding process: Aggregates are fed into the silo area 211 through the transition silo feed port 2111 for temporary storage, and powder materials are fed into the weighing silo 31 through the powder material feed port 32 and are measured by the weighing silo 31. During the feeding process, the transition silo discharge door 2113 and the powder weighing discharge door 34 are closed.

[0026] Feeding process: the transition bin discharge door 2113 is opened, and the aggregate enters the mixing main unit 1 from the transition bin discharge port 2112. At the same time, the powder weighing discharge door 34 is opened, and the powder enters the mixing main unit 1 through the discharge pipe 33. The weighing bin 31 measures the feeding amount of the powder and closes after the powder feeding is completed. As the aggregate and powder are added to the mixing main unit 1, dust is generated in the mixing main unit 1 and the pressure increases. The pulse bag dust collector 22 in the dust removal area 212 works, and the air inlet 2121 absorbs the dust-containing gas in the mixing main unit 1, and is discharged from the air outlet 2121 after filtering, thereby dealing with the dust in the mixing main unit 1 and reducing the excessive pressure in the mixing main unit 1. The function of the first ventilation pipe 23 is that when the pressure of the mixing main unit 1 rises too high, the gas inhaled by the dust removal area 212 is not enough to offset the rising pressure in the mixing main unit 1, then the first ventilation 23 discharges part of the gas to the outside to maintain the mixing main unit 1 The air pressure inside and outside is balanced; similarly, if the gas suction rate in the dust removal area 212 is greater than the pressure rise rate of the mixing main unit 1, the first ventilation pipe 23 introduces air into the mixing main unit 1 to keep the air pressure inside the mixing main unit 1 balanced with that of the outside; the powder scale 3 is provided with a second ventilation pipe 35, and the mixing main unit 1 and the weighing bin 31 are connected by the second ventilation pipe 35, so that the pressure inside the mixing main unit 1 and the weighing bin 31 are kept balanced in real time, thereby avoiding the phenomenon of pulling or supporting the weighing in the weighing bin 31 causing inaccurate measurement; since the connection between the first ventilation pipe 23 and the mixing main unit 1 and the connection between the discharge pipe 33 and the mixing main unit 1 are respectively located on both sides of the connection port between the bin body 21 and the mixing main unit 1, if the powder dust wants to reach the connection between the first ventilation pipe 23 and the mixing main unit 1, it must first pass through the connection port of the transition bin 2, and the powder dust will first be absorbed by the air inlet 2122 in the connection port 24, thereby preventing the powder dust from entering the first ventilation pipe 23.

[0027] Mixing process: the transition bin discharge door 2113 and the powder scale discharge door 34 are closed, and the mixing main unit 1 is working. The dust generated when the mixing main unit 1 is working is absorbed by the dust removal area 212 and filtered and discharged through the pulse bag dust collector 22. Air is introduced into the mixing main unit through the first ventilation pipe 3 to offset the influence of the gas inhaled in the dust removal area 212 on the pressure inside the mixing main unit 1, so as to keep the mixing main unit 1 consistent with the external air pressure.

[0028] Unloading process: The mixing main unit 1 is unloading, and the first ventilation pipe 23 introduces gas into the mixing main unit 1 to keep the internal pressure of the mixing main unit 1 consistent with the external pressure, ensuring the stability of the unloading process.

[0029] The dust collector 22 is integrated in the transition bin 2, and the structure of the mixing main building is more compact, which saves space and can reduce one maintenance platform, thereby reducing maintenance costs; the transition bin discharge port 2112 and the air inlet 2122 form the connection port 24 of the transition bin 2, which has a higher utilization rate of the opening of the mixing main unit 1, and the dust removal area 212 is directly connected to the mixing main unit 1, eliminating the dust collector connecting pipe, and has the advantages of large air volume, small wind loss, and good dust removal effect.

[0030] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
