Detailed Description
Grain dust is basically composed of fat, protein, starch, cellulose, ash, and the like. Any grain contains dust and new dust is also produced during the flow process. The dust in the grain is deposited dust under the relative static condition, and does not form flying dust cloud. The process of changing from dust to a dust cloud is called dusting. The dust is easy to be dusted because the specific gravity of the dust in the grain is smaller than that of the grain, and the particle diameter is less than dozens of micrometers. The dust cloud produced by discharging of the discharging pipe of the ship loader is mainly formed by that after materials are contacted with the lower part of a cabin, air in the cabin is rapidly extruded to drive dust in grain flow, and in addition, bulk grains flow in a telescopic chute of the ship loader to force the air in the chute to flow at a high speed, and the generated air flow causes the dust to fly upwards and is also an important reason for generating the dust. For the dust, the dust is treated by adopting a technology, and the dust can be removed only by adopting a method of combining collection and absorption.
A preferred embodiment of the invention is shown in figures 2 and 3. In the specific implementation, the relevant parameters of the ship loader and the dust removal device are calculated firstly. In this embodiment, the design flow of the ship loader is 500t/h, i.e. the material flow rate is 139kg/s, and the specific gravity of the material pile is 0.65t/m3. Calculated, the air quantity generated by the ship loader during operation is 4800m3/h。
In this embodiment, the telescopic chute 102, the dust collection cover 106 and the dust collection pipe 101, which can be automatically extended and retracted up and down in a stepless manner, are the most important links in the whole dust removing device. The upper part of the telescopic chute 102 is connected with a conveying mechanism 105, a dust collecting cover 106 is arranged at the lower port of the telescopic chute, and the dust collecting pipe 101 is arranged along the telescopic chute and can be vertically stretched along with the telescopic chute. In this embodiment, the diameter of the telescopic chute is 400 mm; the diameter of the dust suction pipe is 320 mm; the dust collecting cover is of a horn mouth type structure with a small upper part and a big lower part, and the size of the lower port of the dust collecting cover is 640 mm. The lower port of the dust collecting cover is provided with a plurality of skirt strips 107 made of rubber sheets which are arranged in an overlapping way to prevent dust from overflowing, so that the dust is effectively sealed and sucked away by the dust collecting pipe.
As can be seen from fig. 2, a suction nozzle is provided on the upper side wall of the dust collection cover 106, and the lower end of the suction pipe 101 is attached to the suction nozzle, and the upper end is connected to the cleaner 103. In this embodiment, the vacuum cleaner 103 is mounted to the front end of the conveyor 105 and can be moved back and forth with the conveyor in such a way that the length of the suction hose is as short as possible. Of course, the vacuum cleaner may be mounted on the frame 104, but the length of the vacuum pipe is greatly increased, and the horizontal section of the vacuum pipe is required to be of a telescopic structure, so that the cost of the whole equipment is increased.
In this embodiment, two sets of distance sensors are provided at the lower port of the dust collection cover 106. One set is an infrared distance sensor which is arranged on the inner side inclined plane of the dust collection cover, the distance between the infrared distance sensor and the lower opening is 600mm, and the sensing distance can be adjusted between 300mm and 600 mm; the other set is a heavy ball type sensor which is arranged outside the dust collection cover, the heavy ball is hung outside the skirt strip 107, when the material is accumulated to reach the position of the heavy ball, the heavy ball can be supported, and the state of the mechanical switch type sensor connected with the heavy ball is changed, so that a sensing signal is sent. The two sensors work in a combined mode, can detect the distance between the lower port of the dust collection cover and the surface of the material, and transmit a detection result signal to the chute control circuit. The slide pipe control circuit can control the telescopic length of the telescopic slide pipe according to the signal of the distance sensor so as to keep the distance between the lower port of the dust hood and the surface of the material within a preset range, in the embodiment, the preset distance (300mm) range is smaller than the length of the skirt strip, thereby ensuring that the dust hood and the grain interface are always kept in close contact, and effectively preventing dust from overflowing. Infrared distance sensors, heavy ball sensors and corresponding control circuits are mature prior art, for example, infrared distance sensors are used in car reversing radars, and therefore they are not described herein again.
The dust collector in the embodiment can adopt the existing dust collector product, and can suck more than 95% of dust when being opened; during shipment, the dust collector discharges the recovered dust again into the telescopic chute and flows along the telescopic chute to the grain in the cabin, which can reduce the environmental pollution and effectively reduce the loss of the grain, because the dust is also useful, for example, as feed.
