Description

Technical Field

[0001] This utility model relates to the field of concrete equipment, and specifically to a dust removal mechanism for a concrete mixing plant. Background Technology

[0002] Conventional concrete preparation methods utilize concrete production lines or batching plants, where cement, fly ash, sand, gravel, fine sand, and admixtures are sequentially fed into a mixer according to a specific ratio and order, and then discharged after reaching a suitable state. While such batching plants can produce concrete, they occupy a significant amount of space. To address this issue, the applicant proposed a foldable modular concrete batching plant, publication number CN117601272A. This invention solves the external dust problem by introducing a pipe from the top of the fly ash silo to an external water tank. However, it requires laying long dust collection pipes and a dust collection water tank, and the batching plant needs an additional water storage tank. In other words, this type of batching plant requires at least one dust collection mechanism and one water storage mechanism to meet the operational needs of the concrete batching plant, and the wastewater cannot be effectively recycled.

[0003] During the improvement process, the inventors found that integrating the water tank and the mixer together can effectively solve this problem. However, since the water tank occupies a certain volume, it will take up a certain space when the mixing plant needs to be folded, making it inconvenient to fold. Therefore, it is necessary to propose a mixing and dust removal mechanism for concrete mixing plants to solve the problems existing in the prior art. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the deficiencies of the prior art by providing a mixing and dust removal mechanism for a concrete mixing plant. This mechanism is installed inside the mixing plant and can solve the problems of dust generation during the operation of the mixing plant, excessive auxiliary equipment, and easy folding.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a mixing and dust removal mechanism for a concrete mixing plant, comprising a mixer, a dust removal water tank, and a track installed inside the concrete mixing plant; the mixer is fixedly installed inside a protective frame, and rollers are installed at the bottom of the protective frame, the rollers are placed on the track and can roll back and forth on the track; the top of the mixer is provided with an exhaust port and a water inlet port, the exhaust port is connected to an exhaust pipe, and the end of the exhaust pipe extends into the dust removal water tank; the water inlet port is connected to a water pumping pipe, the end of the water pumping pipe extends into the dust removal water tank, and a water pump is installed on the water pumping pipe.

[0006] Preferably, the dust removal water tank is provided with a drain inlet at one end.

[0007] Preferably, a screw mounting block is welded onto the stirrer, and a corresponding fixing block is welded onto the protective frame; the stirrer is mounted on the protective frame by screws and nuts.

[0008] Preferably, the roller is also equipped with a braking device.

[0009] Preferably, the top of the agitator is also provided with an additive weighing mechanism.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention, by incorporating a mixer and a dust collection water tank within the batching plant, allows for the pre-preparation of cement mortar. During the preparation process, dust generated in the mixer is discharged into the dust collection water tank via a pipe, effectively solving the dust problem during processing. The dust collection water tank serves both dust removal and water storage functions, eliminating the need for an additional water storage tank. It also further reduces the space occupied by components within the batching plant. Wastewater generated during operation, such as wastewater from cleaning the cement slurry mixer and concrete mixing host, is recycled into the dust collection water tank for reuse. Furthermore, when the batching plant is in operation, the mixer and dust collection water tank are placed on opposite sides of the track. When folding the batching plant, the dust collection water tank is removed, and the mixer is moved to the position of the dust collection water tank for fixation. This design further reduces the space occupied by the dust collection water tank when placed independently within the batching plant, facilitating the folding of the batching plant.

[0012] In summary, this utility model can solve the problems of dust and wastewater reuse, eliminate the need for a water storage tank, save manufacturing costs, and the equipment occupies less space, making the mixing plant more portable. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] like Figures 1 to 3 As shown, a dust removal mechanism for a concrete mixing plant specifically includes a mixer 1, a dust removal water tank 2, and a track 3 installed within the concrete mixing plant. The mixer 1 is fixedly installed within a protective frame 4, and rollers 41 are installed at the bottom of the protective frame 4. The rollers 41 are placed on the track 3 and can roll back and forth on the track 3. The top of the mixer 1 is provided with an exhaust port 11 and a water inlet 12. The exhaust port 11 is connected to an exhaust pipe 5, and the end of the exhaust pipe 5 extends into the dust removal water tank 2. The water inlet 12 is connected to a water pumping pipe 6, and the end of the water pumping pipe 6 extends into the dust removal water tank 2. A water pump (not shown in the figure) is installed on the water pumping pipe 6.

[0020] The principle of dust removal and water addition in this utility model is as follows: In the precast cement mortar stage, a certain amount of water is pre-filled into the dust removal water tank 2, and then a certain amount of cement is input into the mixer 1 through the auger conveying mechanism. During the cement conveying process, the dust generated in the mixer 1 is input into the dust removal water tank 2 through the exhaust pipe 5. The dust in the dust removal water tank 2 is continuously absorbed by the water, and the cement dust enters the water in the dust removal water tank 2. After a certain amount of cement is added, admixtures and water need to be added to the mixer 1. At this time, the water pump on the water pumping pipe 6 can be started to pump the water and cement mixture in the dust removal water tank 2 into the mixer 1. Since the cement-water mixture and cement are not from the same source, it will not affect the quality of concrete. Therefore, a single water tank can solve the dust problem generated during the precast cement mortar stage and reduce the need for a water storage tank. The admixture can be added through the admixture adding mechanism.

[0021] To facilitate the inspection and replacement of the agitator 1, a screw mounting block 13 is welded onto the agitator 1, and a corresponding fixing block 42 is welded onto the protective frame 4. The agitator 1 is mounted on the protective frame 4 with screws and nuts. This connection method facilitates the disassembly and maintenance of the equipment.

[0022] To facilitate the weighing of additives, the top of the mixer 1 is also equipped with an additive weighing mechanism 14, which is an existing device.

[0023] To facilitate braking of the roller 41 and to secure the entire protective frame 4, the roller 41 is also equipped with a braking device. The braking device only needs to be able to stop the roller 41, and any existing braking device can be selected.

[0024] Since the dust removal water tank 2 needs to be regularly drained of waste residue and wastewater and replenished with water, a drain inlet 21 is provided at one end of the dust removal water tank 2. Water is added to or drained from the dust removal water tank 2 through this drain inlet 21.

[0025] The specific working principle of this utility model is as follows: Figure 4 and 5 As shown, this utility model is an auxiliary device for a batching plant, installed within the plant, but it can also be used as a standalone unit. When the entire batching plant needs to be folded, the exhaust pipe 5 and water pumping pipe 6 are removed beforehand. Then, the dust collector water tank 2 is removed from the track 3, and the mixer 1 is pushed to the dust collector water tank 2 and braked in place. When the entire batching plant needs to be extended, the mixer 1 is pushed to the other end of the track 3, and the dust collector water tank 2 is placed in its original position. The mixer 1 and the dust collector water tank 2 are then connected via the exhaust pipe 5 and water pumping pipe 6. Finally, it should be noted that the mixer 1 in this utility model is a conventional concrete mixer, and its structure will not be described in detail.

[0026] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
