Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a pulse dust removal machine for rice processing. Background Art

[0002] Rice is mixed with various impurities such as sand, gravel, soil, coal dust, nails, rice straw and weed seeds. A large amount of dust will be produced during the processing. In order to ensure the cleanliness of the factory and avoid dust pollution, dust collectors are often used to collect dust.

[0003] After searching, Chinese patent CN217094289U discloses a bag-type pulse dust collector for rice processing. In this application, a vibration motor is used to drive a mesh tube to rotate and sieve dust in broken rice. The broken rice is discharged by opening a solenoid valve, and the broken rice can be effectively recovered. However, the gas containing broken rice and dust enters the mesh tube in a vertical falling state, and the separation effect of dust and rice is not very good. A large amount of dust is still easily attached to the collected broken rice, and more dust is attached to the mesh tube after multiple filtrations, which affects the separation effect of dust and broken rice. Therefore, we propose a pulse dust collector for rice processing. Utility Model Content

[0006] By adopting the above technical scheme, the gas containing broken rice and dust enters into the interior of the sub-screening mesh tube through the feed pipe, and when the dust and broken rice are separated in the sub-screening mesh tube, the fan is turned on to suck the dust out of the sub-screening mesh tube from the outside, so that the dust adheres to the cloth bag and then the pulse component is used for pulse dust removal. At this time, the dust attached to the broken rice in the sub-screening mesh tube is separated more thoroughly and can be recovered through the discharge pipe, thereby improving the quality of broken rice recovery. The dust after the pulse is discharged through the ash discharge pipe. After the broken rice is collected, the driving component drives the cleaning component to move up and down, which is convenient for cleaning the sub-screening mesh tube from the outside, thereby ensuring that the sub-screening mesh tube has a good dust filtering effect, and the supporting component supports the cleaning component to rise and fall more stably outside the sub-screening mesh tube.

[0013] The utility model is further configured as follows: the driving assembly includes a mounting sleeve mounted on the inner wall of the casing, a motor mounted on the inner bottom wall of the mounting sleeve, a threaded rod connected to the motor output shaft and movably connected to the inner top wall of the mounting sleeve, and a lifting block threadedly connected to the outside of the threaded rod, one end of the lifting block is movably connected to the inner wall of the mounting sleeve, and the other end of the lifting block is fixedly connected to the mounting ring.

[0014] By adopting the above technical solution, the motor is started to drive the threaded rod to rotate, the lifting block is threadedly connected to the threaded rod and movably connected to the inner wall of the mounting sleeve, so that the lifting block drives the mounting ring to perform lifting and lowering movements on the mounting sleeve, and the brush can clean the side wall of the sub-screen tube from top to bottom.

[0015] The utility model is further configured as follows: the support assembly comprises a guide rod mounted on the fixed net and a guide block sleeved outside the guide rod and connected to the mounting ring.

[0016] By adopting the above technical solution, when the mounting ring moves up and down, the guide block moves up and down along with the mounting ring outside the guide rod, providing an additional support point for the movement of the mounting ring and improving the stability of the movement of the mounting ring.

[0017] The utility model is further configured as follows: the discharge pipe is also provided with a solenoid valve for controlling the discharge.

[0018] By adopting the above technical solution, the broken rice is collected after being separated from the dust, and the electromagnetic valve is opened to discharge the collected broken rice from the discharge pipe to complete the recovery of the broken rice.

At this time, the dust attached to the broken rice in the sub-screening mesh tube is separated more thoroughly and can be recovered through the discharge pipe, thereby improving the quality of the broken rice recovery. After the broken rice is collected, the driving component drives the cleaning component to move up and down, which is convenient for cleaning the sub-screening mesh tube from the outside, thereby ensuring that the sub-screening mesh tube has a good dust filtering effect, and the supporting component supports the cleaning component to rise and fall more stably outside the sub-screening mesh tube.
