Description

Technical Field

[0001] The utility model relates to the field of powder material storage, in particular to a calcium aluminate aggregate bin. Background Art

[0002] Calcium aluminate is one of the main components of concrete, and is generally put into the processing and production of concrete in the form of powder. Therefore, general concrete production enterprises need to store a large amount of calcium aluminate powder. And the colloid formed by calcium aluminate powder suspended in the air and inhaled by the human body will cause occupational diseases such as pneumoconiosis. And every time calcium aluminate is taken, calcium aluminate is vibrated, and finally there is still more or less calcium aluminate dust escaping into the air. And general concrete processing enterprises usually adopt the method of sprinkling water to reduce dust escape. This method treats the symptoms rather than the root cause, and there is still a risk of calcium aluminate dust floating again after the water dries. Content of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a calcium aluminate aggregate bin.

[0004] The utility model is realized by adopting the following technical scheme: a calcium aluminate aggregate bin, including a bin body for storing calcium aluminate, a material opening is arranged at the top of the bin body, and a bin cover is arranged at the material opening for sealing or opening the material opening, and one side of the bin cover is rotatably connected to the bin body;

[0005] An air seal assembly is arranged on the side wall of the material opening, the side wall of the material opening is hollow to form an installation cavity, the air seal assembly is fixed on the inner wall of the installation cavity, a first air hole and a second air hole are arranged on the side wall of the material opening, and the first air hole and the second air hole are symmetrically distributed with the center of the material opening as the center;

[0006] The air port of the air seal assembly faces the first air hole and the second air hole. When the air seal assembly is started, the air seal assembly blows air from the first air hole to the second air hole, and an air film is formed between the first air hole and the second air hole.

[0007] The air seal assembly includes a blowing part and a suction part. The blowing part is arranged on the inner wall of the installation cavity and the blowing port of the blowing part faces the first air hole. The suction part is arranged on the inner wall of the installation cavity and the suction port of the suction part faces the second air hole.

[0008] The blowing part includes an air pump and a blowing pipe. The air pump is fixed on the inner wall of the installation cavity. A pressure relief hole is arranged on the side wall of the installation cavity. The blowing port of the air pump is communicated with the first air hole through the blowing pipe. One end of the blowing pipe is fixedly sealed with the air pump, and the other end of the blowing pipe is fixedly sealed with the first air hole.

[0009] The suction part includes a vacuum pump and a suction pipe. The vacuum pump is fixed in the installation cavity. The suction port of the vacuum pump is communicated with the second air hole through the suction pipe. One end of the suction pipe is fixedly sealed with the vacuum pump, and the other end of the suction pipe is fixedly sealed with the second air hole.

[0010] A guide plate is arranged in the suction pipe. The interior of the bin body is hollow to form a storage cavity. The suction pipe is communicated with the storage cavity through a collection pipe. One end of the guide plate is fixed on the pipe wall of the suction pipe, and the other end of the guide plate is fixed at the connection between the suction pipe and the collection pipe. A plurality of filter holes are formed in the guide plate.

[0011] A collection port is formed in the side wall of the storage cavity. An observation door is arranged at the collection port. One side of the observation door is rotatably connected to the outer wall of the bin body for closing or opening the collection port.

[0012] Compared with the prior art, through the combined action of the blowing part and the suction part, the present utility model forms a high-pressure air film at the material port to isolate the air flow inside and outside the bin body. When using the calcium aluminate powder stored in the bin body or loading the calcium aluminate powder into the bin body, the dust formed by the shaken calcium aluminate powder will be suppressed in the bin body due to the existence of the high-pressure air film and will not overflow from the material port. And even if a small amount of calcium aluminate dust is inhaled into the second air hole, it will be inhaled into the storage cavity for temporary storage, further reducing the risk of calcium aluminate dust escaping.

[0016] Next, in combination with the drawings and specific embodiments, the present utility model will be further described. It should be noted that on the premise of no conflict, the following described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.

[0017] Referring to Figure 1-2, a calcium aluminate aggregate silo, comprising a silo body for storing calcium aluminate. A feeding port is opened at the top of the silo body, and a silo cover is provided at the feeding port for sealing or opening the feeding port. One side of the silo cover is rotatably connected to the silo body. An air sealing assembly is provided on the side wall of the feeding port. When the silo cover is opened, the air sealing assembly starts to work, or the air sealing assembly is in a working state regardless of whether the silo cover is opened or not. The air sealing assembly forms an air film at the feeding port to cover the feeding port. When taking or adding calcium aluminate, the calcium aluminate dust appears in a suspended state due to vibration and other reasons and floats towards the feeding port. When it is blocked by the air film, it finally still falls inside the silo body, that is, the dust formed by calcium aluminate particles basically will not escape into the surrounding environment, thereby reducing the surrounding dust content and reducing the possibility of inhalation by the staff.

[0018] When the air sealing assembly is installed, to ensure that the air sealing assembly does not block the feeding port, an installation cavity needs to be formed in the middle of the side wall of the feeding port. The air sealing assembly is fixed on the inner wall of the installation cavity. The first air hole and the second air hole are opened on the side wall of the feeding port, and the first air hole and the second air hole are symmetrically distributed around the center of the feeding port. The air port of the air sealing assembly faces the first air hole and the second air hole. When the air sealing assembly is started, the air sealing assembly blows air from the first air hole to the second air hole, and an air film is formed between the first air hole and the second air hole. The air flow blows out from the first air hole and is inhaled from the second air hole to form a laminar flow of the air flow. Even if there is a small amount of dust, the dust will be blown by the air flow so that the dust moves towards the second air hole direction and will not escape into the surrounding environment, thereby reducing the surrounding dust content and reducing the possibility of inhalation by the staff.

[0019] The air seal assembly can only use the blowing part. When only using the blowing part, the blowing part needs to blow air into the second air hole, and the second air hole needs to be connected to the external environment. At this time, if a small amount of dust floats, it is very likely to escape to the surrounding environment through the second air hole, so that the air seal effect cannot actually be achieved. On this basis, the air seal assembly includes a blowing part and a suction part. The blowing part is arranged on the inner wall of the installation cavity and the blowing port of the blowing part faces the first air hole. The suction part is arranged on the inner wall of the installation cavity and the suction port of the suction part faces the second air hole. The blowing part includes an air pump and a blow pipe. The air pump is fixed on the inner wall of the installation cavity. A pressure relief hole is opened on the side wall of the installation cavity. The blowing port of the air pump is connected to the first air hole through the blow pipe. One end of the blow pipe is fixedly sealed with the air pump, and the other end of the blow pipe is fixedly sealed with the first air hole. The suction part includes a vacuum pump and a suction pipe. The vacuum pump is fixed in the installation cavity. The suction port of the vacuum pump is connected to the second air hole through the suction pipe. One end of the suction pipe is fixedly sealed with the vacuum pump, and the other end of the suction pipe is fixedly sealed with the second air hole. That is, the air flow blown out by the air pump is blown out from the first air hole, and finally a low-pressure area is formed near the second air hole by the pumping action of the vacuum pump. Therefore, the air flow blown out from the first air hole will inevitably flow to the second air hole, that is, an air film is formed between the first air hole and the second air hole. The air flow is blown out from the first air hole and sucked into the second air hole to form a laminar flow of the air flow. Even if there is a small amount of dust, it will be blown by the air flow and move the dust towards the second air hole, and will not escape to the surrounding environment, thereby reducing the dust content in the surrounding area and reducing the possibility of inhalation by the staff.

[0020] After a small amount of dust is sucked into the second air hole, it will move towards the vacuum pump through the suction pipe. At this time, a guiding plate needs to be provided in the suction pipe. The inside of the bin body is hollow to form a storage cavity. The suction pipe is connected to the storage cavity through a collecting pipe. One end of the guiding plate is fixed on the pipe wall of the suction pipe, and the other end of the guiding plate is fixed at the connection between the suction pipe and the collecting pipe. Several filtering holes are opened on the guiding plate. A collecting port can be opened on the side wall of the storage cavity. An observation door is provided at the collecting port. One side of the observation door is rotatably connected to the outer wall of the bin body for closing or opening the collecting port. When the storage cavity is full, the observation door can be opened to take out the calcium aluminate dust temporarily stored in the storage cavity, which is more convenient and reduces material waste at the same time.

[0021] Compared with the prior art, the utility model forms a high-pressure air film at the material port through the combined action of the blowing part and the suction part to isolate the air flow inside and outside the bin body. When using the calcium aluminate powder stored in the bin body or loading the calcium aluminate powder into the bin body, the dust formed by the shaken calcium aluminate powder will be suppressed in the bin body due to the existence of the high-pressure air film and will not overflow from the material port. And even if a small amount of calcium aluminate dust is sucked into the second air hole, it will be sucked into the storage cavity for temporary storage, further reducing the risk of calcium aluminate dust escaping.

[0022] The above embodiments are only the preferred embodiments of the present utility model, and the scope of protection of the present utility model cannot be limited thereby. Any non-substantive changes and substitutions made by those skilled in the art based on the present utility model fall within the scope of protection required by the present utility model.
