Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust removal workbenches for coal preparation, in particular to an automatic dust removal workbench for coal preparation. Background Art
[0002] Coal sample preparation is to prepare coal samples for coal tests (chemical analysis) from large-grained coal through steps such as crushing, mixing, reduction, and drying. All work after the coal sample is crushed to 3 mm is carried out on the workbench. During the preparation process, tools such as sieves and riffle splitters are frequently used, resulting in a large amount of coal dust in the air and sundries on the workbench surface near the workbench. Especially for coal samples dried at 0.2 mm, the coal dust volatilizes severely. Even if employees wearing special masks work in the sample preparation room for a long time, the effect is average. Being in such a working environment for a long time will cause certain harm to the health of the staff.
[0003] Therefore, in order to protect the health of personnel, an automatic dust removal workbench for coal preparation is urgently needed to solve the above-described technical problems. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to overcome the above technical defects and provide an automatic dust removal workbench for coal preparation.
[0005] To solve the above technical problem, the technical solution provided by the utility model is an automatic dust removal workbench for coal preparation, including:
[0006] A workbench;
[0007] A dust-proof cover body is provided above the workbench. A cavity is provided inside the dust-proof cover body. A plurality of round holes are evenly provided on both side inner walls, the top inner wall, and the rear inner wall of the dust-proof cover body. The round holes are communicated with the cavity. A first dust discharge port communicated with the cavity is provided at the upper end of the dust-proof cover body. An upper air collecting cover is provided at the upper end of the first dust discharge port. An upper dust discharge pipe is provided on the upper air collecting cover;
[0008] A plurality of through holes are evenly provided at the upper end of the workbench. The through holes extend to the inside of the workbench. A lower air collecting cover is provided at the inner top of the workbench. A channel communicated with the lower air collecting cover is provided at the lower end of the lower air collecting cover. A second dust discharge port is provided at the rear end of the workbench. The channel is communicated with the second dust discharge port. A rear air collecting cover is provided at the second dust discharge port at the rear end of the workbench. A rear dust discharge pipe is provided on the rear air collecting cover;
[0009] A main pipe is provided on the rear dust discharge pipe. The upper end of the main pipe is communicated with the upper dust discharge pipe.
[0010] As an improvement, a dust removal device is further included. The lower end of the main pipe is communicated with the dust removal device.
[0011] As an improvement, the lower air collecting hood covers the entire inner top surface of the workbench.
[0012] The advantages of the present utility model compared with the prior art are as follows:
[0013] 1. A dust-proof cover body is provided above the workbench, and a plurality of round holes are evenly provided on the inner walls on both sides, the top inner wall, and the rear inner wall of the dust-proof cover body. In this way, the dust-proof cover body can prevent coal dust and small coal blocks from running around during the working process, confining them within the dust-proof cover body to a certain extent, protecting the environment of the operation room. The coal dust and dust volatilized above the workbench and within the space covered by the dust-proof cover body are timely sucked away through the round holes. On the one hand, this avoids being inhaled by the workers, and on the other hand, it also protects the operation environment, making the working environment more hygienic;
[0014] 2. A plurality of through holes are evenly provided at the upper end of the workbench, and the through holes extend to the inside of the workbench. A lower air collecting hood is provided at the inner top of the workbench. In this way, it can effectively suck away the dust and various sundries on the tabletop, making the tabletop of the workbench cleaner and easier to clean; Since there is suction from the through holes, it can also prevent the dust on the workbench from being lifted.
