Description

Technical Field

[0002] Rice processing is to separate the endosperm and other parts of rice with the minimum degree of crushing to make rice with better edible quality. A lot of dust will be generated in the process of separating the husk, cortex, embryo and endosperm of rice. In addition, various impurities such as sand, gravel, soil, coal dust, nails, rice straw and weed seeds mixed in the rice will also form dust. The treatment of these dusts is a particularly important part of the rice processing industry. Generally, bag dust collectors are used to treat these dusts in rice production and processing. Bag dust collectors are a dry dust filtering device, which is suitable for capturing fine, dry, non-fibrous dust.

[0003] However, the lower bin and upper bin of the traditional bag dust collector are fixed by bolts. When the dust removal components inside the bag dust collector need to be repaired, they can only be repaired from the top of the upper bin. A cover is provided on the upper bin, which is mostly fixed to the top of the upper bin by bolts. In addition, the upper bin is located at a high position, which is not convenient for maintenance and repair of the internal components.

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Fig. 9 and Fig.12 As shown, the pulse bag dust collector for rice processing of the present invention comprises four supporting legs 1, a dust removal structure 2 installed on the four supporting legs 1, an adjusting structure 3 installed on the dust removal structure 2, a sealing structure 4 arranged on the dust removal structure 2, a limiting structure 5 arranged on the dust removal structure 2, and a fixing structure 7 arranged on the dust removal structure 2;

[0038] The dust removal structure 2 includes a mounting frame 201 and an upper bin 202 fixedly connected to the mounting frame 201, the four supporting legs 1 are fixedly connected to the mounting frame 201, the mounting frame 201 is slidably connected to the lower bin 203, the interior of the upper bin 202 is fixedly connected to a flower plate 204, a cloth bag 205 is installed on the flower plate 204 through a quick-release structure 6, a counterweight 212 is fixedly connected to the bottom end of the cloth bag 205, an exhaust pipe 209 is fixedly connected to the upper bin 202, a fan 210 is provided on the open space on one side of the supporting leg 1, the exhaust pipe 209 is fixedly connected to the fan 210 at one end facing away from the upper bin 202, and an air inlet pipe 211 is fixedly connected to one side of the lower bin 203;

[0039] The regulating structure 3 includes a connecting pipe 301 and a fixed pipe 302 slidably connected to the connecting pipe 301. The end of the air inlet pipe 211 is fixedly connected to the connecting pipe 301, and the bottom end of the fixed pipe 302 is fixedly connected to two branch pipes 304. The end of the fixed pipe 302 is provided with a cover 303; a pulse valve 206 is installed on the upper chamber 202, and a plurality of blowing pipes 207 are fixedly connected to the pulse valve 206. The blowing pipes 207 pass through the upper chamber 202, and the bottom end of each blowing pipe 207 is fixedly connected to a plurality of nozzles 208; The end of the tube 301 away from the air inlet pipe 211 is fixedly connected with two sealing rings 305, and the sealing ring 305 conflicts with the fixed tube 302; when the rice is processed, the fan 210 is started, and the fan 210 extracts the air inside the upper warehouse 202 and the lower warehouse 203 through the exhaust pipe 209, so that the upper warehouse 202 and the lower warehouse 203 are in a negative pressure state, and the lower warehouse 203 extracts the gas inside the fixed tube 302 through the air inlet pipe 211 and the connecting pipe 301, and the fixed tube 302 is in a negative pressure state. Before removing the ash, the branch pipe 304 is fixed with a hose, and the hose can be connected to the bran outlet of the rice machine. Next, when the fan 210 is working, the dust from the dust rice machine bran outlet will be sucked into the lower bin 203. The larger dust particles will directly fall into the ash hopper of the lower bin 203, and the smaller dust will be filtered by the bag 205 and adsorbed on the bag 205. The filtered gas enters the exhaust pipe 209 from above the flower plate 204 and is finally discharged by the fan 210. The dust on the bag 205 gradually increases. When the internal operating pressure of the equipment is high, the pulse valve 206 will be started, and the compressed air will be ejected from the pulse valve 206, and sprayed to the bag 205 through the blowing pipe 207 and multiple nozzles 208. The bag 205 The instantaneous expansion vibration causes the dust on the surface to fall into the ash hopper of the lower bin 203. The discharge valve on the lower bin 203 can be opened laterally to discharge the collected dust. Since the fixed pipe 302 is fixed to the wall by a bracket, during installation, it is only necessary to connect the air inlet pipe 211 with the connecting pipe 301. Since the connecting pipe 301 and the fixed pipe 302 are slidably connected, repeated adjustment of the lateral position of the lower bin 203 and the upper bin 202 can be avoided, making installation more convenient. The setting of the sealing ring 305 improves the sealing between the connecting pipe 301 and the fixed pipe 302, so that the dust removal effect is better.

The setting of the inner support frame 611 also improves the stability of the cloth bag 205 and improves the use effect of the cloth bag 205.

[0044] When the present invention is in use, first, when rice is processed, the fan 210 is started, and the fan 210 extracts the air inside the upper warehouse 202 and the lower warehouse 203 through the exhaust pipe 209, so that the upper warehouse 202 and the lower warehouse 203 are in a negative pressure state, and the lower warehouse 203 extracts the gas inside the fixed pipe 302 through the air inlet pipe 211 and the connecting pipe 301, and the fixed pipe 302 is in a negative pressure state. Before dust removal, a fixed hose is fixed on the branch pipe 304, and the hose can be connected to the bran outlet of the rice machine. When the fan 210 is working, the dust from the bran outlet of the dust rice machine will be sucked into the lower warehouse 203, and larger particles of dust will directly fall into the ash hopper of the lower warehouse 203, and smaller dust will be filtered by the cloth bag 205 and adsorbed on the cloth bag 205, and the filtered gas enters the exhaust pipe 209 from above the flower plate 204, and is finally discharged by the fan 210, and the cloth bag The dust on 205 gradually increases. When the internal operating pressure of the equipment is relatively high, the pulse valve 206 will be activated, and compressed air will be ejected from the pulse valve 206, and sprayed to the cloth bag 205 through the blowing pipe 207 and multiple nozzles 208. The cloth bag 205 will expand and vibrate instantly, causing the dust on the surface to fall into the ash hopper of the lower bin 203. The discharge valve on the lower bin 203 can be opened later to discharge the collected dust. Since the fixed pipe 302 is fixed to the wall by a bracket, it is only necessary to connect the air inlet pipe 211 with the connecting pipe 301 during installation. Since the connecting pipe 301 is slidably connected to the fixed pipe 302, it is possible to avoid repeatedly adjusting the lateral position of the lower bin 203 and the upper bin 202, making the installation more convenient. The setting of the sealing ring 305 improves the sealing between the connecting pipe 301 and the fixed pipe 302, so that the dust removal effect is better.

[0045] Then, when the lower bin 203 needs to be opened, the handle 505 needs to be slid upward, the handle 505 drives the block 502 to rise, the tension spring 504 extends, and the block 502 no longer engages with the slot 503 on the slide frame 401. At this time, the slide frame 401 and the lower bin 203 can be slid out, and when the slide frame 401 is about to slide out, the tension spring 504 resets and drives the block 502 to engage with another slot 503 on the slide frame 401, thereby preventing the slide frame 401 from being stuck with the lower bin 203 at the bottom. 03 moves, and when the lower warehouse 203 moves, it will push the connecting pipe 301 to move inside the fixed pipe 302. The connecting pipe 301 also pulls the lower warehouse 203 to make the lower warehouse 203 more stable. At this time, the bottom end of the upper warehouse 202 is completely open, and the operator can wear goggles to replace and repair the cloth bag 205 at the bottom. When the cloth bag 205 is repaired and replaced, the handle 505 can be slid upwards. After the handle 505 drives the block 502 to not engage with the card slot 503, Slide the slide frame 401 and the lower bin 203 toward the upper bin 202. Since two sets of rollers 404 with different heights are provided at the bottom of the slide frame 401, the rollers 404 roll on the stepped boss 405. When both sets of rollers 404 roll to the platform portion of the boss 405, the sealing gasket 402 on the slide frame 401 is just engaged with the sealing groove 403 at the bottom of the upper bin 202, thereby improving the sealing between the upper bin 202 and the lower bin 203. Then release the handle 505, and the tension spring The reset of 504 drives the card block 502 to engage with the card slot 503 on the slide frame 401, thereby fixing the slide frame 401 and the lower bin 203, improving the stability of the lower bin 203, and the setting of the guide rod 501 improves the sliding stability of the card block 502, while preventing the tension spring 504 from running off, and the bottom end cross section of the card block 502 is a trapezoidal structure, which improves the smoothness of the slide frame 401 when it is pushed inward, and the setting of the roller 404 improves the smoothness of the slide frame 401 when it moves;

[0046] Finally, when the cloth bag 205 needs to be installed, by holding the inner support frame 611 inside the cloth bag 205, the sliding sleeve 602 at the top of the cloth bag 205 is aligned with the hole on the flower plate 204 and then the two connecting strips 609 are pressed.
