[0002] During the pouring and production of concrete products, water vapor dust (referring to waste gas containing water vapor and dust) will be generated. These water vapor dust cannot be discharged directly into the atmosphere; generally, dust collection systems are used to recover the dust. Existing dust collection systems include Figure 1 As shown, a bag filter (200) is arranged on the top of the lime powder bin (100), and the bag filter (200) includes a dust bin (210) and an ash hopper (220) located below the dust bin (210), the output end of the ash hopper (220) is connected to the lime powder bin (100), and a feeder (230) for discharging materials is arranged in the ash hopper (220); a plurality of bags (not shown) for filtering are arranged in the dust bin (210), and a dust collecting pipe (300) and an exhaust pipe (400) are connected to the dust bin (210), and the dust collecting pipe (300) transports dust containing water vapor into the dust bin (210), and the dust is filtered by the bags, and the filtered dust enters the ash hopper (220), and the filtered air is discharged from the exhaust pipe (400). The dust entering the ash hopper (220) is sent to the lime powder bin (100) via the feeder (230) and used as raw material. Due to the high water vapor content, the dust is easy to clump, which can easily cause the bag and ash hopper in the bag filter to be blocked, resulting in frequent maintenance, heavy maintenance workload and high costs. Summary of the invention

[0003] In view of this, the present invention proposes a concrete pouring dust collection system, aiming to reduce the maintenance frequency and maintenance workload of the existing dust collection system.

[0004] The technical solution of the present invention is achieved in this way:

[0005] A concrete pouring dust collection system comprises a lime powder bin, a bag dust collector is arranged on the top of the lime powder bin, the lime powder bin is connected to a dust collecting pipe, the bag dust collector comprises a dust removal bin and a bag arranged in the dust removal bin, the dust removal bin is connected to the lime powder bin, and an exhaust pipe is arranged on the dust removal bin.

[0006] As a further optional solution, a buffer is provided on the top of the lime powder bin, a buffer chamber is provided in the buffer, the buffer chamber is communicated with the lime powder bin, and the dust collecting pipe is connected to the buffer.

[0007] As a further optional solution, a guardrail is provided at the top edge of the lime powder bin.

[0008] As a further optional solution, the exhaust pipe is connected to an induced draft fan.

[0009] As a further optional solution, a ladder is provided on the side of the lime powder bin.

[0010] Compared with the prior art, the concrete pouring dust collection system of the present application has at least the following beneficial effects:

[0011] The dust collection system adjusts the path of the dust containing water vapor, and uses the dust collection pipe to first pass the dust containing water vapor into the lime powder bin, and cleverly uses the water absorption characteristics of the quicklime powder in the lime powder bin to absorb the water vapor in the dust containing water vapor and generate calcium hydroxide. The generated calcium hydroxide falls into the lime powder bin, and the dust after the water vapor is removed enters the dust removal bin from the lime powder bin and is filtered by the bag. The filtered air is discharged from the exhaust pipe. Among them, the dust containing water vapor first passes through the lime powder bin to remove water vapor before entering the dust removal bin, avoiding the bag from being blocked and reducing the maintenance frequency; at the same time, the original ash hopper and feeder on the bag dust collector are omitted, reducing the structural complexity and manufacturing cost of the dust collection system.

[0022] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] refer to Figure 2 An embodiment of the present invention shows a concrete pouring dust collection system, including a lime powder bin 1, a bag dust collector 2 is arranged on the top of the lime powder bin 1, the lime powder bin 1 is connected to a dust collecting pipe 3, the bag dust collector 2 includes a dust removal bin 21 and a bag arranged in the dust removal bin 21, the dust removal bin 21 is connected to the lime powder bin 1, and an exhaust pipe 4 is arranged on the dust removal bin 21.

[0024] The dust collecting system adjusts the path of the dust containing water vapor, and first passes the dust containing water vapor into the lime powder bin 1 by using the dust collecting pipe 3, and cleverly uses the water absorption characteristics of the quicklime powder in the lime powder bin 1 to absorb the water vapor in the dust containing water vapor and generate calcium hydroxide. The generated calcium hydroxide falls into the lime powder bin 1, and the dust after the water vapor is removed enters the dust removal bin 21 from the lime powder bin 1 and is filtered by the bag, and the filtered air is discharged from the exhaust pipe 4. Before entering the dust removal bin 21, the dust containing water vapor first passes through the lime powder bin 1 to remove water vapor, so as to avoid the bag from being blocked and reduce the maintenance frequency; at the same time, the original ash hopper 220 and feeder 230 on the bag filter 2 are omitted, so as to reduce the structural complexity and manufacturing cost of the dust collecting system.

[0025] In some embodiments, Figure 2As shown, a buffer 5 is provided on the top of the lime powder bin 1, a buffer chamber (not marked in the figure) is provided in the buffer 5, the buffer chamber is communicated with the lime powder bin 1, and the dust collecting pipe 3 is connected to the buffer 5. In this embodiment, the water vapor dust in the dust collecting pipe 3 is not directly passed into the lime powder bin 1, and the buffer 5 is used as a transfer transition to avoid the water vapor dust in the dust collecting pipe 3 causing too much airflow impact on the environment in the lime powder bin 1.

[0026] In addition, a valve (not shown) can be set between the buffer 5 and the lime powder bin 1 to control the connection between the buffer chamber and the lime powder bin 1; similarly, a valve (not shown) can also be set between the lime powder bin 1 and the dust removal bin 21 to control the connection.

[0027] The above scheme is specific, such as Figure 2 As shown, the exhaust pipe 4 is connected to an induced draft fan 41. The induced draft fan 41 can lead out the airflow, which can offset the airflow entering the lime powder bin 1 from the dust collecting pipe 3, so that the air pressure in the lime powder bin 1 is relatively stable.

[0028] Specifically, the top edge of the lime powder silo 1 is provided with a guardrail 11 , so that the safety of the maintenance personnel working on the top of the lime powder silo 1 can be guaranteed.

[0029] In the above scheme, a ladder 12 is provided on the side of the lime powder bin 1. The ladder 12 can be used to climb to the top of the lime powder bin 1 or to leave from the top of the lime powder bin 1.

[0030] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
