Description
Technical Field
[0001] The utility model relates to the technical field of wallboard raw material processing devices, in particular to a dust removal device for a crusher. Background Art
[0002] Wall panels are the main raw material in the furniture and construction industries. In recent years, countries around the world have paid attention to forest protection, and logging restrictions and bans have been widely implemented. Due to insufficient supply, wood is in short supply, which has led to manufacturers and consumers increasingly choosing cheaper integrated boards. The production process is to press integrated wall panels using bamboo powder, stone powder and plastic powder. The preparation of powders such as bamboo powder, stone powder and plastic powder requires the bamboo, lime and plastic to be crushed.
[0003] During the crushing process of bamboo, wood, lime and plastic, a large amount of dust will be generated at the discharge and discharging ends of the crushing device, causing smoke in the production workshop. This not only makes the working environment of employees poor, but also affects the health of employees after they inhale dust for a long time.
[0004] The existing wet dust removal device not only wastes a lot of water, but also causes a lot of dust to accumulate on the inner wall of the device. In addition, the dust removal effect of the existing wet dust removal device located at the crusher discharge port is poor. Utility Model Content
[0005] In order to overcome at least one of the defects of the prior art described above, the present invention provides a dust removal device for a pulverizer to solve the problem of poor dust removal effect at the pulverizer outlet.
[0006] The technical solution adopted by the present invention to solve the problem is:
[0007] A dust removal device for a grinder comprises a dust box, wherein the lower end of the dust box is provided with an outlet, the upper end of the dust box is provided with a water tank, the upper side of the dust box is provided with a spraying mechanism, the spraying mechanism is connected to the water tank, a buffer wheel is rotatably connected inside the dust box, a hair dryer for providing power to the buffer wheel is provided on one side of the dust box, a connecting mechanism is provided on one side of the dust box, the connecting mechanism is used to connect with the grinder, the connecting mechanism comprises a main pipe, an upper pipe and a lower pipe, the main pipe is connected to one side of the dust box, one end of the upper pipe and the lower pipe are both connected to the main pipe, and the other end is used to connect with the grinder.
[0008] Through the above scheme, the spraying mechanism can atomize water into fine water droplets, which are fully in contact with the inhaled dust-laden gas, so that the dust adheres to the water droplets and settles down, thereby processing the dust. The buffer wheel can receive the falling mist water, so that the mist water can be concentrated and fall to the lower end of the dust collection box. The hair dryer can provide power to the buffer wheel and blow off the water and dust on the buffer wheel.
[0009] Furthermore, the spraying mechanism includes a main water pipe, two horizontal spraying pipes and several longitudinal spraying pipes. The main water pipe runs through the dust collection box and is connected to the water tank. The two horizontal spraying pipes are fixedly installed on the main water pipe, and the several longitudinal spraying pipes are fixedly connected to the horizontal spraying pipes. Several spray heads are provided on the horizontal spraying pipes and the longitudinal spraying pipes.
[0010] Through the above further solution, since the spraying mechanism includes two horizontal spraying pipes and several longitudinal spraying pipes, and multiple spray heads are provided on each pipe, this can ensure that the entire space in the dust collection box can be covered by water mist, thereby improving the dust removal efficiency. When a spray head fails, the other spray heads can still work normally and will not immediately affect the operation of the entire system.
[0011] Furthermore, the buffer wheel is provided with a circle of several evenly arranged blades.
[0012] Through the above-mentioned further solution, the blades on the buffer wheel help to guide and disperse the mist containing dust in the dust collection box, which is conducive to improving the contact efficiency between the spraying mechanism and the dust-laden gas, thereby improving the dust removal effect.
[0013] Furthermore, an air outlet is provided on one side of the dust box next to the buffer wheel, the air outlet faces the blades below the buffer wheel, an air diffuser is provided on the side of the air outlet located inside the dust box, and the air outlet is connected to the hair dryer on the side outside the dust box.
[0014] Through the above-mentioned further solution, the design of the air diffuser helps to evenly spread the airflow entering the dust box, avoiding excessive concentration of the airflow in a certain area. This can ensure that the airflow inside the entire dust box is more uniform, prevent the airflow from affecting the dust above the buffer wheel, and better blow away the water mist and dust on the buffer wheel.
[0015] Furthermore, a plurality of inclined plates evenly arranged downward are provided in the dust collection box below the buffer wheel.
[0016] Through the above further solution, the presence of the inclined plate can make the fallen water and dust slide down from the top, reduce the flow speed of water and dust, and thus facilitate the reception of wastewater at the outlet.
[0017] Furthermore, the main connecting pipe is located between the spraying mechanism and the buffer wheel, and an exhaust fan is provided on the main connecting pipe.
[0018] Through the above further solution, suction force can be provided to the upper pipe and the lower pipe, thereby attracting dust.
[0019] Furthermore, a dust collecting head connected to the feed end of the crusher is provided on the connecting end between the upper connecting pipe and the main connecting pipe.
[0020] Through the above further solution, the dust collection head is directly installed at the feed end of the grinder, which can immediately capture the dust generated when the material enters the grinder, thereby reducing the dust from escaping into the working environment and improving the overall dust removal efficiency.
[0021] Furthermore, a dust suction ring connected to the discharge end of the crusher is provided on the connecting end of the lower connecting pipe and the main connecting pipe. A plurality of dust suction holes for attracting dust are provided on the inner ring of the dust suction ring, and expansion suction heads are provided on the plurality of dust suction holes.
[0022] Through the above further solution, the dust collection ring is directly installed at the discharge end of the crusher, which can capture the dust generated immediately after the material is received, thereby reducing the dust from escaping into the working environment and improving the overall dust removal efficiency. The dust collection holes and expansion nozzles on the dust collection ring can evenly distribute the airflow, ensuring that the dust coming out of the crusher discharge end is effectively sucked into the dust collection box.
[0023] In summary, the dust removal device for a pulverizer provided by the present invention has the following technical effects:
[0024] 1. The spraying mechanism can atomize water into fine water droplets, which are in full contact with the inhaled dust-laden gas, so that the dust adheres to the water droplets and settles, thereby treating the dust.
[0025] 2. The buffer wheel cooperates with the hair dryer to receive the falling mist containing dust, so that the mist containing dust can be concentrated. The hair dryer can provide power for the buffer wheel and blow off the mist containing dust on the buffer wheel, and then the mist containing dust falls onto the inclined plate.
