Description

Technical Field

[0001] This utility model relates to the field of powder collection equipment, specifically to a powder collection system for a mixing plant. Background Technology

[0002] Concrete is a building material made by mixing cement as the main binder with raw materials such as sand, gravel, lime, and cinders in a pre-mixed proportion. Currently, concrete is usually prepared in concrete mixing plants. A mixing plant is a complete set of equipment used to produce concrete, consisting of systems and structural components for feeding, storing, batching, mixing, discharging, and controlling materials.

[0003] During operation, existing mixing plants typically use a material weighing system to weigh and proportion raw materials such as sand, gravel aggregates, and cement, which are then transported to the mixer via a material conveying system for mixing. When the sand, gravel aggregates, and cement enter the mixer, a large amount of material powder is generated. This material powder will escape into the air. When the concentration of material powder in the air exceeds a certain value, it will cause pollution. Current technology usually uses cloth bags to collect and clean this material powder, but the collection method of cloth bags is not convenient for sampling, testing, or recycling the collected material powder. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a material powder collection system for mixing plants that adopts a side-mounted filter collection structure and a cleaning mechanism to facilitate the sampling and testing of collected material powder by workers, in view of the current status of the existing technology.

[0005] This utility model is achieved through the following technical solution: This utility model proposes a material powder collection system for a mixing plant, including a collection pipeline, a lateral pipeline fixedly connected to one side wall of the collection pipeline, the number of lateral pipelines being not less than one, and a fan and a material powder filter plate installed inside the lateral pipeline. The feature is that a cleaning mechanism is rotatably connected inside the collection pipeline, the cleaning end of the cleaning mechanism facing the material powder filter plate, for cleaning the material powder accumulated on the material powder filter plate.

[0006] By adopting the above technical solution, the upper end of the collection pipe extends into the interior of the mixer to collect the material powder that escapes from the air inside the mixer. The fan can perform air extraction operations through the side pipe and the collection pipe, so that the air can carry the material powder into the collection pipe and the side pipe and complete the collection under the action of the material powder collection plate.

[0007] Furthermore, there are two lateral pipelines, which are evenly distributed vertically in the same direction, or symmetrically distributed horizontally, or staggeredly distributed horizontally.

[0008] By adopting the above technical solutions, the lateral pipelines with different distribution patterns can improve their collection effect according to different powder particles.

[0009] Furthermore, the cleaning mechanism consists of a connecting bracket and a filter brush plate. The filter brush plate is fixedly installed at one end of the connecting bracket, and a rotating shaft is formed at the other end of the connecting bracket. The rotating shaft is embedded in the inner wall of the collection pipe and is rotatably connected.

[0010] By adopting the above technical solution, the filter brush plate can rotate under the action of the rotating shaft to complete the brushing operation.

[0011] Furthermore, both ends of the rotating shaft are fixedly connected to connecting shafts, which pass through the collection pipe and are rotatably connected by bearings. Each connecting shaft has a handle fixedly installed on its outer end.

[0012] By adopting the above technical solution, the operator can drive the connecting shaft and the rotating shaft through the handle.

[0013] Furthermore, the lower end of the collection pipe is formed with a discharge port, a sealing plate is slidably connected inside the discharge port, and a lifting handle is formed at the upper end of the sealing plate.

[0014] By adopting the above technical solution, the sealing plate can control the opening and closing of the discharge port.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] This invention, by setting up a collection pipeline, a side pipeline, a powder filter plate, and a cleaning mechanism, enables the mixing plant to use the powder collection pipeline to recover the powder that escapes from the air inside the mixer during operation. The side pipeline and powder filter plate are used to collect the powder contained in the extracted air. At the same time, the cleaning mechanism can conveniently collect and clean the collected powder, so that the staff can sample and test the powder or recycle it for reuse.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] First embodiment: as follows Figures 1-3 As shown in this embodiment, a material powder collection system for a mixing plant includes a collection pipe 1. A lateral pipe 2 is fixedly connected to one side wall of the collection pipe 1. The number of lateral pipes 2 is not less than one. A fan 3 and a material powder filter plate 4 are installed inside the lateral pipe 2. The system is characterized in that a cleaning mechanism 5 is rotatably connected inside the collection pipe 1. The cleaning end of the cleaning mechanism 5 faces the material powder filter plate 4 and is used to clean the material powder accumulated on the material powder filter plate 4.

[0026] This application provides a material powder collection system for a mixing plant, which employs a side-mounted filter collection structure and a cleaning mechanism to facilitate sampling and testing of the collected material powder. This solves the problem in existing technologies where cloth bags are used to collect and clean material powder dispersed in the air, but this method is inconvenient for sampling, testing, or recycling. The overall approach to solving this problem is as follows: by setting up a collection pipeline, the mixing plant can use collection pipeline 1 to collect material powder dispersed in the air inside the mixer during operation. This is combined with a side pipeline 2 and a material powder filter plate 4 to collect the material powder contained in the extracted air. Simultaneously, the cleaning mechanism 5 facilitates convenient collection and cleaning of the material powder, allowing for sampling, testing, or recycling.

[0027] like Figures 1-3 As shown, there are two lateral pipes 2, which are evenly distributed vertically in the same direction;

[0028] As one implementation method, the upper and lower distributed lateral pipes 2 can complete the air guiding and discharge operation in turn under the action of the fan 3. When the upper lateral pipe 2 has been operating for a long time, the corresponding powder filter plate 4 is prone to blockage after collecting a large amount of powder, which reduces its filtration and collection effect. At this time, the lower lateral pipe 2 can be replaced to start the operation, and the alternating operation mode can be completed to ensure that its filtration and collection effect remains in good working condition.

[0029] like Figures 3-5 As shown, the cleaning mechanism 5 consists of a connecting bracket 501 and a filter brush plate 502. The filter brush plate 502 is fixedly installed at one end of the connecting bracket 501, and a rotating shaft 503 is formed at the other end of the connecting bracket 501. The rotating shaft 503 is embedded in the inner wall of the collection pipe 1 and rotates in connection with it.

[0030] In one implementation, the filter brush plate 502 can rotate around the rotating shaft 503 with the support of the connecting bracket 501. The filter brush plate 502 has bristles or teeth formed on one end face facing the powder filter plate 4, which can brush and clean the powder filter plate 4 during its rotation, so as to avoid the accumulation of a large amount of powder on the powder filter plate 4, causing blockage or reducing its filtration effect.

[0031] like Figures 3-5 As shown, both ends of the rotating shaft 503 are fixedly connected to the connecting shaft 504, which passes through the collection pipe 1 and is rotatably connected by bearings.

[0032] In one embodiment, the rotating shaft 503 and the connecting shaft 504 are on the same axis. The connecting shaft 504 can extend the rotation driving point of the rotating shaft 503 to both sides, so that it can extend to the outside of the collection pipe 1, so that the operator can drive the rotation of the rotating shaft 503.

[0033] like Figures 3-5 As shown, handles 505 are fixedly installed on the outer ends of the connecting shaft 504;

[0034] In one implementation, the handle 505 provides a gripping point for the operator to hold the connecting shaft 504, facilitating the operator's operation.

[0035] like Figures 3-5 As shown, the lower end of the collection pipe 1 is formed with a discharge port 6, and a sealing plate 7 is slidably connected inside the discharge port 6. The upper end of the sealing plate 7 is formed with a lifting handle.

[0036] In one implementation, the powder particles collected by the powder filter plate 4 can fall into the discharge port 6 under the cleaning action of the cleaning mechanism 5 and be discharged through the discharge port 6, so that the staff can conduct sampling tests or recycle and reuse them.

[0037] The specific implementation process of this embodiment is as follows: The upper end of the collection pipe 1 extends into the mixer to collect the material powder that escapes from the air inside the mixer. During operation, the fan 3 in one of the side pipes 2 is started. The fan 3 can discharge the air in the side pipe 2 and the collection pipe 1, so that the collection pipe 1 is in a negative pressure state, which can extract the air in the mixer and allow the material powder that escapes from the air to enter the collection pipe 1. The material powder that enters the collection pipe 1 will enter the corresponding side pipe 2 under the action of the corresponding fan 3. When it enters the side pipe 2, it will be filtered and collected by the material powder filter plate 4. When the material powder filter plate 4 has a lot of material powder adhering to its surface after a long period of operation, its filtration and collection effect will be greatly reduced. At this time, the current fan 3 is turned off, and the fan 3 in another side pipe 2 is started to work, so that the air can carry the material powder into the corresponding side pipe 2, and then the material powder filter plate 4 in the side pipe 2 takes over the filtration and collection operation to ensure that the material powder collection system maintains a good working state.

[0038] Second embodiment: The difference from the first embodiment is that there are two lateral pipes 2, which are symmetrically or staggeredly distributed in the left and right directions (not shown in the figure).

[0039] The implementation method of this embodiment is as follows: The lateral pipes 2 distributed on the left and right can start operation simultaneously when facing relatively dense powder particles or large particle volume, thereby enhancing the powder collection effect of the collection pipe 1.

[0040] For example, when the powder particles are dense or large, the powder on the side of the collection pipe 1 adjacent to the side pipe 2 is more easily collected, while the powder on the side away from the side pipe 2 is less effectively collected. Therefore, the side pipes 2 distributed on both sides can make up for this deficiency and ensure the efficient and complete collection of powder in the collection pipe 1.

[0041] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
