Description

Technical Field

[0001] The utility model belongs to the field of rice processing, and particularly relates to a temperature reduction mechanism for rice polishing. Background Technique

[0002] A polishing machine, also known as a grinding machine, is often used for mechanical grinding, polishing and waxing. Its working principle is that the motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at a high speed. Due to the combined action of the polishing disc and the polishing agent and the friction with the surface to be polished, the purpose of removing paint surface pollution, oxide layer and shallow scratches can be achieved. Now, when processing rice, a polishing machine is also used to treat the impurities on the outer surface of the rice.

[0003] The Chinese utility model patent is CN220405715U, which discloses a water-cooled temperature reduction device for rice polishing, belonging to the field of rice processing technology. It includes a rice polishing machine, a water-cooled temperature reduction box and a feeding cylinder. The top of the rice polishing machine is fixedly communicated with a feeding hopper, the top of the water-cooled temperature reduction box is fixedly communicated with a feeding hopper, the inner wall of the water-cooled temperature reduction box is uniformly and fixedly installed with temperature reduction plates, the inner wall of the temperature reduction plates is fixedly installed with a first water-cooled pipe, a material passing hole is opened at the top of the temperature reduction plates, the top of the water-cooled temperature reduction box is fixedly connected with a stirring motor, the bottom of the stirring motor is fixedly connected with a driving shaft, and stirring blades are uniformly and fixedly installed on the outer wall of the driving shaft corresponding to the temperature reduction plates. A feeding hopper is fixedly installed on the inner wall of the rice polishing machine, and a feeding screw is rotatably connected to the feeding cylinder;

[0004] The above design cools the unpolished rice through the water-cooled pipe to reduce the temperature of the rice itself and reduce the probability of the rice being broken during polishing. However, there are certain problems in use, that is, the polishing roller inside the polishing machine will gradually increase its temperature due to long-term work. This temperature will also affect the rice received for processing, causing the rice to break due to excessive temperature during polishing, resulting in the deterioration of the working quality of the polishing machine itself.

[0005] To solve the above problems, a temperature reduction mechanism for rice polishing is proposed in this application. Content of the Utility Model

[0027] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given in conjunction with the accompanying drawings of the specification.

[0028] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0029] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present utility model. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that are mutually exclusive of other embodiments. The present utility model provides the following embodiments.

[0030] As Figure 1 , Figure 2 and Figure 3 shown, a temperature reduction mechanism for rice polishing includes a processing bin 1, polishing rollers 2, a water outlet pipe 3, and a water inlet pipe 4. The polishing rollers 2 are symmetrically and rotatably installed inside the processing bin 1. A water outlet pipe 3 is arranged on one side inside the processing bin 1. The water inlet pipe 4 is fixedly installed on the side of the processing bin 1. Temperature reduction mechanisms 5 are arranged on both sides of the polishing rollers 2. The temperature reduction mechanism 5 includes a connecting pipe 51, a top shell 52, an outer shell 53, a limiting ring 54, a conveying groove 55, and a flow groove 56. Outer shells 53 are rotatably installed outside the output ends on both sides of the polishing rollers 2. The top shell 52 is fixedly installed at the top of the outer shell 53. The connecting pipe 51 is fixedly installed at the top of the top shell 52. The connecting pipe 51 is fixedly connected to the water inlet pipe 4. Limiting rings 54 are fixedly installed at the output ends on both sides of the polishing rollers 2. The limiting rings 54 are rotatably connected to the outer shells 53. A conveying groove 55 is jointly opened inside the polishing rollers 2 and the outer shells 53. A flow groove 56 is opened inside the polishing rollers 2. The flow groove 56 is communicated with the conveying groove 55. The temperature reduction mechanism 5 is used to convey cooling water into the polishing rollers 2 to reduce the overall temperature of the polishing rollers 2. A water cooling mechanism 6 is arranged at the bottom end of the water outlet pipe 3. The water cooling mechanism 6 is used to remove the heat inside the cooling water. A collection mechanism 7 is arranged on one side inside the processing bin 1. The collection mechanism 7 is used to collect the separated waste materials.

[0031] In use, the rice to be polished is introduced into the interior of the processing bin 1, and then the rice is polished by using the polishing roller 2. Moreover, by using the water inlet pipe 4 and the cooling mechanism 5, the temperature of the whole polishing roller 2 is controlled. Through the use of the water inlet pipe 4, cooling water is input into the connecting pipe 51, and then directly input into the flow groove 56 through the conveying groove 55. When the polishing roller 2 is working, the connecting shafts on both sides of the polishing roller 2 will rotate. However, due to the cooperation of the outer shell 53 and the limiting ring 54, the outer shell 53 itself will not rotate together with the polishing roller 2. Then, the cooling water flows into the water outlet pipe 3, completing the reduction of the temperature inside the polishing roller 2. Moreover, due to the use of the water cooling mechanism 6, while treating the heat in the water source, the polished rice by the polishing roller 2 is blown, separating the impurities inside the rice. Finally, through the use of the collection mechanism 7, the separated impurities are collected, facilitating subsequent centralized treatment.

[0032] As shown in the attached Figure 4 In this embodiment, as shown, reinforcing rings are symmetrically and fixedly installed inside the polishing roller 2, and flow holes are equidistantly arranged inside the reinforcing rings, which are used to ensure the stable operation of the polishing roller 2 itself and also facilitate the circulation of the water source, ensuring the stability of the internal structure of the polishing roller 2 on the premise of ensuring the circulation of the water source during use.

[0033] As shown in the attached Figure 4 In this embodiment, as shown, a reinforcing member is fixedly installed on the side of the outer shell 53, and the reinforcing member is fixedly connected to the inner wall of the processing bin 1, which is used to ensure the stability of the outer shell 53 itself during use. During use, through the installation of the reinforcing member, the position of the outer shell 53 itself is fixed and will not rotate synchronously with the rotating shaft of the polishing roller 2.

[0034] As shown in the attached Figure 5 In this embodiment, as shown, the water cooling mechanism 6 includes a heat dissipation pipe 61, an installation groove 62, a fan group 63, and a side baffle 64. The heat dissipation pipe 61 is fixedly installed at the bottom end of the water outlet pipe 3. An installation groove 62 is provided on one side inside the processing bin 1. The fan group 63 is fixedly installed inside the installation groove 62. A side baffle 64 is fixedly installed inside the processing bin 1, and the side baffle 64 is installed on the side of the fan group 63.

[0035] During use, the water outlet pipe 3 will input the water source with heat into the heat dissipation pipe 61, and then through the use of the fan group 63, the heat in the water source is removed. Moreover, due to the cooperation of the side baffle 64, the impurities in the rice polished by the polishing roller 2 can be blown, and all the impurities are blown to the other side of the inner wall of the processing bin 1, facilitating subsequent collection.

[0036] As shown in the attached Figure 5As shown, in this embodiment, circular notches are equidistantly formed inside the side baffle 64 for discharging the air generated by the fan group 63 to the side. During use, through the formation of the circular notches, on the premise of ensuring the air flow, rice can be placed into the installation groove 62.

[0037] As shown by the appendix Figure 6 As shown, in this embodiment, the collection mechanism 7 includes a storage tank 71, a collection tank 72 and a cover plate 73. A storage tank 71 is formed on one side inside the processing chamber 1, a collection tank 72 is formed on the side surface of the processing chamber 1, the collection tank 72 is communicated with the storage tank 71, and a cover plate 73 is rotatably installed on the side of the processing chamber 1.

[0038] During use, through the use of the storage tank 71, the impurities separated by the water cooling mechanism 6 are collected. Subsequently, the cover plate 73 can be directly opened to expose the collection tank 72, and all the impurities in the storage tank 71 can be directly taken out from the inside of the collection tank 72.

[0039] As shown by the appendix Figure 6 As shown, in this embodiment, a baffle plate is fixedly installed at the top of the storage tank 71 inside the processing chamber 1 for preventing rice from directly falling into the storage tank 71. During use, it can prevent some impurities from being directly blown to the top part of the processing chamber 1, affecting the normal use of the polishing roller 2 itself.

[0040] As shown by the appendix Figure 1 As shown, in this embodiment, a discharge port is formed directly below the two polishing rollers 2 inside the processing chamber 1 for directly discharging the polished rice. During use, it is convenient to quickly discharge the qualified rice polished by the polishing rollers 2.

[0041] The above content further elaborates on the present invention in combination with specific implementation manners. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention pertains, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, which should all be regarded as falling within the protection scope determined by the claims submitted for the present invention.
