DETAILED DESCRIPTION

[0020] The utility model will be further described below in conjunction with the accompanying drawings.

[0021] like Figure 1 and Figure 2As shown, the preferred embodiment of the utility model of the double-twist dragon double-slag-dropping-zone intelligent environmentally friendly vibrating screen comprises a vibrating screen 1, a pulse dust collector 2, a conveying device 3 and a frame 4. The vibrating screen 1, the pulse dust collector 2 and the conveying device 3 are all mounted on the frame 4. The vibrating screen 1 is located at one end of the frame 4, and the vibrating screen 1 is used to screen grains and grain residues. Specifically, the vibrating screen 1 has a slag outlet 11 arranged along the width direction of the vibrating screen 1 and a material outlet arranged along the length direction of the vibrating screen 1. The slag outlet 11 is used to discharge the screened grain residues, and the material outlet is used to discharge grains and remaining grain residues. The pulse dust collector 2 is connected to the material outlet of the vibrating screen 1, and is used to suck away the grain residues dropped from the material outlet, and collect the grain residues and discharge them in a centralized manner. The conveying device 3 is located below the material outlet, and the conveying device 3 is used to receive the grains dropped from the grain outlet and convey them to the outside.

[0022] The frame 4 has wheels 41, which can facilitate the movement of the entire equipment; at the same time, a slag collecting bucket 42 is arranged on the frame 4, and the slag outlet 11 of the vibrating screen 1 is correspondingly arranged with a slag collecting bucket 42, and the pulse filter is also correspondingly provided with its own slag collecting bucket 42. The slag collecting bucket 42 is used to gather the discharged grain slag, avoiding the dispersion of the grain slag and making it convenient to use a container to hold the grain slag.

[0023] The pulse dust collector 2 includes a connecting pipe 21, a shell 22, a pulse tube 23, a filter bag 24, an exhaust fan 25 and a slag auger 26. The vibrating screen 1 extends into the lower end of the connecting pipe 21, the upper end of the connecting pipe 21 is fixed to the shell 22, the connecting pipe 21 is connected to the inner cavity of the shell 22, and the rice residue enters the inner cavity of the shell 22 through the connecting pipe 21. The shell 22 is provided with an observation window 224, which is convenient for observing the operation inside the shell 22. The filter bag 24 is installed in the inner cavity, and the filter bag 24 is used to filter the rice residue, so that the rice residue can only be deposited in the inner cavity of the shell 22. The exhaust fan 25 is installed on the shell 22 and communicated with the inner cavity of the shell 22. The exhaust fan 25 extracts the gas filtered by the filter bag 24 and discharges it from the shell 22, that is, the exhaust fan 25 extracts the air in the pulse bag, so that a negative pressure is generated in the filter bag 24 in the shell 22. The negative pressure is further transmitted to generate a negative pressure in the inner cavity of the shell 22, so that the rice residue is sucked away by the connecting pipe 21. While sucking away the rice residue, the grain will not be sucked away, and the grain will fall to the conveying device 3 below the connecting pipe 21. The pulse tube 23 is installed in the inner cavity of the shell 22. The pulse tube 23 is used to blow air into the filter bag 24. The pulse tube 23 and the exhaust fan 25 operate alternately, so as to ensure that the rice residue can be filtered, and the rice residue attached to the filter bag 24 can be reduced, and the time when the filter bag 24 is blocked can be extended. The slag auger 26 is installed at the bottom of the shell 22 to discharge the collected rice residue out of the shell 22.

[0024] The lower end of the connecting pipe 21 has a connecting port and a grain outlet, the discharge port of the vibrating screen 1 extends into the connecting pipe 21 through the connecting port, an air inlet is provided on the shell 22, and the upper end of the connecting pipe 21 is installed at the air inlet, so that the air outlet of the connecting pipe 21 is connected to the inner cavity of the shell 22.

[0025] The inner cavity of the shell 22 is divided into a sedimentation chamber 221, a filter chamber 222 and a clean chamber 223. The sedimentation chamber 221 is connected with the filter chamber 222. The filter chamber 222 and the clean chamber 223 are separated by a mounting plate 27. The filter bag 24 is mounted on the mounting plate 27 to connect the filter chamber 222 and the clean chamber 223. Two observation windows 224 are provided, and the sedimentation chamber 221 and the filter chamber 222 are correspondingly provided. The connecting pipe 21 is connected to the sedimentation chamber 221. The height of the connecting pipe 21 is less than the height of the sedimentation chamber 221. Therefore, after the grain residue and air enter the sedimentation chamber 221, the flow rate will slow down, which is convenient for the sedimentation of grain residue. The grain residue is deposited at the bottom of the sedimentation chamber 221, reducing the grain residue entering the filter chamber 222. At the same time, the air outlet of the connecting pipe 21 is aligned with the top of the sedimentation chamber 221, so that the flow rate distribution of the grain residue and air in the sedimentation chamber 221 gradually decreases from the top to the bottom, further increasing the amount of grain residue deposition, that is, further reducing the grain residue entering the filter chamber 222; in this way, the service life of the filter bag 24 can be further extended. A guide 28 is provided in the sedimentation chamber 221. The guide 28 is located at the upper end of the sedimentation chamber 221. The guide 28 is preferably installed at the top of the sedimentation chamber 221 to slow down the flow rate of the top grain residue and air, so that the grain residue can fall to the bottom of the sedimentation chamber 221 by gravity. The pulse tube 23 is installed in the clean chamber 223. The pulse tube 23 is provided with nozzles corresponding to the filter bags 24. The nozzles spray the high-pressure gas in the pulse tube 23 to the filter bags 24, flushing the grain residue attached to the filter bags 24 and letting the grain residue fall to the bottom of the filter chamber 222. The bottom of the sedimentation chamber 221 and the filter chamber 222 are both provided with a collecting bucket 29. Each of the collecting buckets 29 is provided with a slag auger 26. The slag auger 26 discharges the grain residue at the bottom out of the housing 22; Figure 3 As shown, the slag outlet 11 of the auger is provided with a slag baffle 261, and the slag baffle 261 is hinged on the auger to slow down the falling speed of the slag and effectively prevent the slag from flying.

[0026] The conveying device 3 is provided with a grain baffle 31 , and both sides of the grain outlet of the connecting pipe 21 are arranged with a grain baffle 31 , so as to gather the grains onto the conveying device 3 .

[0027] The unscreened grains are put onto the vibrating screen 1, and the vibrating screen 1 discharges the screened grain residue from the residue outlet 11, and discharges the grains that meet the requirements and the grain residue that cannot be screened from the discharge port. The mixture of grains and grain residues enters the connecting pipe 21, and the grains fall toward the grain outlet under the action of gravity and finally fall onto the conveying device 3, while the grain residues are sent into the sedimentation chamber 221 under the action of the negative pressure of the connecting pipe 21, and the relatively heavy grain residues are deposited in the sedimentation chamber 221 and deposited to the bottom of the sedimentation chamber 221. The remaining grain residues enter the filter chamber 222 and are then filtered by the grain residue filter bag, and then the pulse tube 23 flushes the grain residues, and the grain residues fall to the bottom of the filter chamber 222 and are discharged through the residue discharge auger 26.

[0028] The grain discharge port of the vibrating screen 1 is connected to a pulse filter, and the grains fall to the conveying device 3 below, and the grain residues are sucked away by the pulse filter. The pulse filter collects the grain residues and discharges them in a centralized manner, effectively preventing dust and fine grain residues from being raised, and effectively improving the working environment.

[0029] The above are only implementation methods of the present utility model, and are not intended to limit the patent scope of the present utility model. Any equivalent structure made using the contents of the specification and drawings of the present utility model, directly or indirectly used in other related technical fields, are also within the patent protection scope of the present utility model.
