Description

Technical Field

[0001] The utility model relates to the technical field of dust treatment, in particular to a dust compression device. Background Art

[0002] Dust generated in industrial production is usually collected and then processed by dust collection devices such as bag filters and cyclone separators. However, the dust collected in the dust collection device is directly unloaded in the dust hopper of the dust collector. Since the dust in the hopper is discharged under the action of gravity and the dust particle structure is loose, and the specific gravity per unit volume is relatively light, not only can secondary dust flying not be avoided, but also the utilization efficiency of the packaging container is low, increasing the transportation times and costs. In addition, if there is no dust disposal unit nearby, the cost of long-distance transfer and disposal is high.

[0003] In addition, due to the dust flying at the dust disposal site, the problem of black water is prominent in the rainy season, and environmental pollution cannot be avoided. Therefore, there is an urgent need for a dust compression device. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the above technical problems and provide a dust compression device with simple structure, convenient use and high dust compression efficiency.

[0005] To achieve the above purpose, the technical scheme adopted by the utility model is as follows.

[0006] A dust compression device, the compression device includes a feed pipe, a screw compressor, a discharge port, a hopper, a discharge pipe, a compression chamber, a compression cylinder, a compression piston and a plug;

[0007] The feed pipe is arranged at the feed end of the screw compressor, the other end of the screw compressor is provided with a discharge port, a hopper is arranged below the discharge port, and a compression chamber is arranged at the bottom of the hopper, and the two are communicated by a discharge pipe;

[0008] The closed end of the compression chamber is provided with a compression cylinder, and the piston of the compression cylinder is arranged in the compression chamber; the other end of the compression chamber is open, and a plug is arranged at the open end.

[0009] Further, the body of the screw compressor is a cone; the screw compressor shaft is connected to the motor through a coupling.

[0010] Further, an exhaust pipe is arranged in the feed pipe; one end of the exhaust pipe extends into the dust hopper of the dust collector.

[0011] Further, a valve is arranged on the discharge pipe.

[0012] Further, the compression cylinder is a pneumatic cylinder, an oil cylinder or a lead screw.

[0013] Further, the plug is movably arranged with the compression chamber.

[0014] Further, the other side of the blocking block is connected to the connecting rod of the telescopic device.

[0015] Further, the telescopic device is a cylinder or an oil cylinder or a lead screw.

[0016] Further, the compression chamber and the compression cylinder are arranged on the first bracket; the telescopic device is arranged on the second bracket.

[0017] Further, the discharge pipe is arranged at a non-end part of the compression chamber.

[0018] A dust compression device provided by the present utility model includes a feed pipe, a screw compressor, a compression chamber, a compression cylinder, a compression piston and a blocking block. The screw compressor is communicated with the dust collector hopper through the feed pipe. The other end of the screw compressor is provided with a discharge port. A hopper is arranged below the discharge port. The bottom of the hopper is provided with the compression chamber, and the two are communicated through the discharge pipe; the closed end of the compression chamber is provided with the compression cylinder, and the piston of the compression cylinder is arranged in the compression chamber; the other end of the compression chamber is open, and a blocking block is arranged at the open end. The dust collected in the dust collection device is first compacted by the screw compressor and then further compacted by the piston driven by the compression cylinder in the compression chamber. The compacted dust block is pushed out of the open end of the compression chamber by the piston. For convenient operation, the blocking block at the open end of the compression chamber is connected to the telescopic device, and the telescopic device drives the blocking block to move, realizing the compression and discharge of the dust in the compression chamber.

[0019] For the dust compression device of the present utility model, the feed pipe connecting the screw compressor and the dust collector hopper is inclined, which can effectively avoid secondary dust flying generated by dust falling into the screw compressor. To avoid air choking in the screw compressor and the feed pipe, an exhaust pipe is arranged in the feed pipe. One end of the exhaust pipe extends into the dust collector hopper, and a top cap is arranged at this end to prevent dust from entering. To improve the compression effect of the screw compressor, the body of the screw compressor is set as a cone, and the feed port is arranged at the conical bottom end of the cone.

[0020] For the dust compression device of the present utility model, by adjusting the pressure of the compression cylinder, the density and hardness of the pressed dust block can be controlled, so as to facilitate subsequent reprocessing.

[0021] During use, the dust collected in the dust collection device first enters the screw compressor through the feed pipe. The screw compressor squeezes the dust into the compression screw in the screw compressor and transports it to the discharge port. The squeezed dust enters the hopper. After collecting enough dust, the valve on the discharge pipe is opened, and the squeezed dust enters the compression chamber. Then the valve on the discharge pipe is closed, and the piston driven by the compression cylinder in the compression chamber further compresses and compacts the squeezed dust. The telescopic device is started, the blocking block is opened, and the compacted dust block is pushed out of the open end of the compression chamber by the piston. After the dust block is discharged, the piston of the compression chamber contracts into the compression chamber, the telescopic device is started, and the blocking block closes the open end of the compression chamber, and then the next operation can be carried out.

[0023] (1) Simple structure and convenient to use.

[0024] (2) High dust compression efficiency.

[0025] (3) Wide application range. BRIEF DESCRIPTION OF THE DRAWINGS
