The main principle is to drive the racks on the two end rings of the car dumper through driving gears to rotate the car dumper, thereby driving the train clamped on the car dumper to rotate. Due to gravity, the materials in the train automatically unload and fall into the hopper. The materials are transported to the belt through a feeder in the hopper and finally transported to the storage yard by a stacker.
[0003] During the unloading process of the existing car dumper, a large amount of dust and pollutants are released into the air. Spraying water is usually used to reduce dust, but this will increase the humidity of the materials, resulting in the need for additional dehumidification work and causing the problem of unnecessary extra work.
[0004] Regarding the problem that the existing car dumper generates a large amount of dust and pollutants during the unloading process, spraying water is usually used to reduce dust, but this will increase the humidity of the materials, resulting in the need for additional dehumidification work and causing the problem of unnecessary extra work. For this reason, we propose a dust removal car dumper. Content of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0025] Referring to Figures 1-4 , an embodiment provided by the present invention: A dust removal tippler includes a tippling unit 1 and a power purification unit 2. The tippling unit 1 functions to fix the carriage for discharging materials, and the power purification unit 2 functions to purify dust. A dust-proof plate 3 is provided on the side wall of the tippling unit 1, and the dust-proof plate 3 functions to prevent dust from overflowing during discharging. An air inlet 4 and a discharge opening 5 are provided on the side wall of the tippling unit 1. The inside of the tippling unit 1 is a dust source area. A power purification unit 2 is provided near the discharge opening 5 on one side of the tippling unit 1. A dust partition plate 6 is provided on the outer wall of the power purification unit 2, and the dust partition plate 6 functions to isolate dust. The bottom of the dust partition plate 6 is fixedly connected to the top surface of the traveling ground 7, and the traveling ground 7 functions to support the movement of the carriage. A vibration wall 11 is fixedly connected to the bottom of the traveling ground 7, and the vibration wall 11 functions to block dust. A suction port 8 is provided on the side of the power purification unit 2 near the discharge opening 5. A filter bag 9 and a fan 10 are provided inside the power purification unit 2, and the filter bag 9 functions to filter the air with dust particles.
[0026] There are two dust-proof plates 3 in total, which are arc-shaped plates and are arranged oppositely, fitting the C-shaped beam of the tippling unit 1, thereby being able to play a sealing role and prevent dust from flying out.
[0027] The negative pressure is balanced everywhere inside the tippling unit 1, and air is supplemented to the dust source area from the air inlet 4, thereby being able to guide the dust to flow towards the power purification unit 2.
[0028] A negative pressure cavity is formed between the power purification unit 2 and the tippling unit 1, thereby being able to prevent dust from flying out from the air inlet 4.
[0029] The power purification unit 2 is provided with two rows of suction ports 8, and the suction ports 8 are grid structures, thereby being able to absorb dust air more comprehensively and prevent materials from being sucked into the purification module during discharging, thus preventing damage to the filter bag 9.
[0030] A filter bag 9 is arranged at the rear of the air suction port 8 in the power purification unit 2, and the top of the filter bag 9 is fixedly connected to the input end of the fan 10, so that the air filtered by the filter bag 9 can be discharged in time.
[0031] A dust-proof plate 3 is arranged on the side wall of the air suction port 8 in the power purification unit 2. The dust-proof plate 3 is composed of two vertical plates and one horizontal plate, thus playing a role in preventing dust from flying out.
[0032] The horizontal plate of the dust-proof plate 3 is tangent to the top of the tipping unit 1, and the two vertical plates of the dust-proof plate 3 are arc-shaped cut, and the shape fits the outer edge of the tipping unit 1, so that it can fit the tipping unit 1 better, thereby reducing the gap and further preventing dust from flying out.
[0033] The vertical distance between the bottom of the tipping unit 1 and the traveling ground 7 is 1 / 3 of the height of the tipping unit 1. When no unloading operation is carried out, the C-shaped opening side of the tipping unit 1 is in contact with the traveling ground 7, and a blanking channel is left between the other side and the traveling ground 7. A silo 13 is arranged at the bottom of the vibrating wall 11, and the material falls into the inside of the silo 13 from the blanking channel, so that the material can be unloaded into the inside of the silo 13 in time. This height can reduce the falling stroke of the material, thereby reducing the generation of dust.
[0034] Spring doors 12 are arranged at the import and export of the two sides of the tipping unit 1. The spring doors 12 play a role in closing the tipping unit 1, further improving the airtightness of the tipping unit 1, thereby preventing dust from flying out.
[0035] Working principle: When the tipping unit 1 is not working, the air enters from the C-shaped opening and between the top of the tipping unit 1 and the dust-proof plate 3. The carriage enters the tipping unit 1 along the track under the traction of the reconditioning machine, and then the unloading operation is carried out. When unloading, after the tipping unit 1 rotates by a certain angle, the top air inlet 4 is closed, and only the C-shaped opening admits air. After the supplementary air enters the dust source area from the air inlet 4, it enters the purification area along the gap between the carriage and the inner wall of the tipping unit 1. The air inlet area is reduced, realizing an increase in the inlet air velocity. The dust separation plate 6 of the power purification unit 2 is connected to the tipping unit 1, so that the tipping unit 1 and the power purification unit 2 form a negative pressure cavity. The volume of the equipment is much smaller than the volume of the workshop. The dust generated during unloading is always in the negative pressure cavity, preventing it from overflowing. The dust raised when the material falls into the silo 13 is blocked by the vibrating wall 11, the traveling ground 7 and the tipping unit 1. The purification module of the power purification unit 2 includes an air suction port 8 and a filter bag 9. The motor drives the fan 10 to provide negative pressure. The dust-containing air passes through the air suction port 8 and the filter bag 9 in turn under the action of negative pressure. The dust adheres to the filter bag 9, and the clean air is discharged through the fan 10. The air suction port 8 is a grid structure, preventing the material from being sucked into the purification module, reducing the air velocity, and avoiding impacting the filter bag 9.
[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
