Description

Technical Field

[0001] The utility model relates to the technical field of nut flotation, in particular to a nut flotation machine. Background Art

[0002] Nut flotation is a method that uses the physical properties of water and air to distinguish the quality of nuts. During flotation, healthy nuts sink due to their higher density, while those that are infested with insects or have internal damage will absorb bubbles and float to the surface due to their loose structure or hollow space. In this way, unqualified nuts can be effectively removed to ensure the quality of the final product.

[0003] A flotation machine is needed in the process of nut flotation. The existing flotation machines can continuously and stably introduce bubbles into the machine body.

[0004] However, since the outer surface of the nuts may be sticky with dirt or debris, and a large amount of clean water is required during the flotation process of the nuts to ensure the cleanliness of the flotation water and avoid the introduction of new pollution, the currently existing flotation machines do not have the functions of nut cleaning and water purification circulation, resulting in dirt and debris still remaining on the outer surface of the nuts after flotation is completed, requiring secondary treatment, wasting too much time and a large amount of water resources, thereby increasing economic costs and being unfavorable for use. Therefore, a nut flotation machine is proposed to solve the above problems. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a nut flotation machine, which solves the problem that the existing flotation machines do not have the function of nut cleaning and water purification circulation, resulting in dirt and debris remaining on the outer surface of the nuts after flotation, requiring secondary treatment, wasting too much time and a large amount of water resources, thereby increasing economic costs and being unfavorable for use.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a nut flotation machine, comprising a machine body, a circulation box, an air pump, a water pump, a receiving box and a bottom plate, wherein a cleaning circulation component is provided on the outside of the machine body;

[0007] The cleaning circulation assembly includes a top cover fixedly installed on the top of the machine body by bolts and nuts, a driving motor is fixedly installed in the middle of the top of the top cover, the output shaft of the driving motor is fixedly connected to the stirring shaft, the water inlet of the water pump is fixedly connected to the suction pipe, the water outlet of the water pump is fixedly connected to the drain pipe, the interior of the circulation box is fixedly connected to the first filter, the second filter and the third filter, and the left side of the circulation box is fixedly connected to the outlet pipe.

[0008] Furthermore, the water extraction pipe is connected to the receiving box, the drainage pipe is connected to the circulation box, and the left and right sides of the top of the top cover are fixedly connected with feeding pipes for pouring nuts and clean water.

[0009] Furthermore, a discharge pipe is fixedly connected to the middle of the bottom end of the machine body, and electromagnetic control valves are installed on the outside of the discharge pipe and the water outlet pipe.

[0010] Furthermore, an air outlet pipe is fixedly connected to the top of the air pump, and both the air outlet pipe and the water outlet pipe are connected to the machine body. The end faces of the air outlet pipe and the water pumping pipe are fixedly connected with an isolation net.

[0011] Furthermore, the machine body and the bottom of the circulation box are fixedly connected with support columns on all sides, and the support columns, circulation box, air pump, water pump and the bottom of the receiving box are all fixedly connected to the top of the base plate.

During nut flotation, the driving motor can drive the stirring shaft to rotate clockwise inside the machine body, so that the stirring blades on the outer surface of the stirring shaft can fully stir the nuts to remove dirt and debris on the outer surface of the nuts, so that the dirt and debris fall into the water. After the nut flotation is completed, qualified nuts and sewage are discharged into the interior of the receiving box through the discharge pipe. At this time, the water pump can cooperate with the water pipe and the drainage pipe to introduce the sewage into the circulation box, so that the sewage is triple-filtered by the first filter screen, the second filter screen and the third filter screen inside the circulation box to fully remove the dirt and debris in the sewage.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 3 In this embodiment, a nut flotation machine includes a body 1, a circulation box 2, an air pump 3, a water pump 4, a receiving box 5 and a bottom plate 6. A cleaning circulation component is provided on the outside of the body 1.

[0022] The cleaning circulation component includes a top cover 7 fixedly installed on the top of the body 1 by bolts and nuts, a driving motor 8 is fixedly installed in the middle of the top of the top cover 7, the output shaft of the driving motor 8 is fixedly connected to the stirring shaft 9, the water inlet of the water pump 4 is fixedly connected to the suction pipe 10, the water outlet of the water pump 4 is fixedly connected to the drain pipe 11, the interior of the circulation box 2 is fixedly connected to the first filter screen 12, the second filter screen 13 and the third filter screen 14, and the left side of the circulation box 2 is fixedly connected to the outlet pipe 15. By setting up the cleaning circulation component, when the nuts are floated, the driving motor 8 can drive the stirring shaft 9 to rotate clockwise inside the body 1, so that the stirring blades on the outer surface of the stirring shaft 9 are used to fully stir the nuts to remove the dirt and debris on the outer surface of the nuts, so that the dirt and debris fall into the water.

[0023] Among them, when the nut flotation is completed, the qualified nuts and sewage wells are discharged into the interior of the receiving box 5 through the discharge pipe 16. At this time, the water pump 4 can cooperate with the pumping pipe 10 and the drainage pipe 11 to introduce the sewage into the circulation box 2, and use the first filter screen 12, the second filter screen 13 and the third filter screen 14 inside the circulation box 2 to perform triple filtration on the sewage to fully remove the dirt and debris in the sewage, and finally re-introduce the purified water into the body 1 through the outlet pipe 15 for recycling.

[0024] Furthermore, compared with the currently available flotation machines, the nut cleaning and water purification circulation functions are realized, which can fully clean the nuts to avoid residual dirt and debris on their outer surface, thereby avoiding wasting too much time, effectively improving work efficiency, and reducing the waste of water resources, thereby significantly reducing economic costs, and it is more convenient to use.

[0025] It should be noted that the mesh sizes of the first filter 12 , the second filter 13 and the third filter 14 are different from each other, wherein the mesh of the first filter 12 is the largest and the mesh of the third filter 14 is the smallest, thereby ensuring the filtering effect.

[0026] Among them, the water suction pipe 10 is connected to the receiving box 5, the drainage pipe 11 is connected to the circulation box 2, and the left and right sides of the top of the top cover 7 are fixedly connected with the feed pipe 19 for pouring nuts and clean water. The middle part of the bottom end of the body 1 is fixedly connected with the discharge pipe 16, and the outside of the discharge pipe 16 and the water outlet pipe 15 are both installed with electromagnetic control valves.

[0027] In addition, the top of the air pump 3 is fixedly connected to an air outlet pipe 17, and the air outlet pipe 17 and the water outlet pipe 15 are both connected to the body 1. The air outlet pipe 17 and the end face of the water pumping pipe 10 are fixedly connected to an isolation net 18. By setting the air outlet pipe 17, the air pump 3 can continuously introduce bubbles into the water, and the isolation net 18 can isolate nuts when the air outlet pipe 17 introduces bubbles and the water pumping pipe 10 pumps water, so as to avoid nuts clogging the pipeline.

[0028] It should be understood that the body 1 and the bottom of the circulation box 2 are fixedly connected with support columns 20 on all sides, and the support columns 20, the circulation box 2, the air pump 3, the water pump 4 and the bottom of the receiving box 5 are all fixedly connected to the top of the base plate 6.

[0029] Among them, a sealing plate 21 is provided on the front of the circulation box 2, and threaded holes 22 are provided on the outer surface of the sealing plate 21 and the circulation box 2. The internal threads of the threaded holes 22 are connected with fixing bolts 23, and a rubber sealing gasket 24 is bonded to the back of the sealing plate 21. By providing a sealing plate 21 that is easy to disassemble and assemble, it is convenient for the staff to clean the dirt and debris remaining on the top of the first filter screen 12, the second filter screen 13 and the third filter screen 14.

[0030] The working principle of the above embodiment is:

[0031] When in use, the staff first needs to pour nuts and clean water into the body 1 through the feed pipe 19. After the pouring is completed, the air pump 3 is started, so that bubbles are continuously introduced into the water through the air outlet pipe 17 to flotation the nuts. When the nuts are flotated, the driving motor 8 can drive the stirring shaft 9 to rotate clockwise inside the body 1, so that the stirring blades on the outer surface of the stirring shaft 9 are used to fully stir the nuts to remove the dirt and debris on the outer surface of the nuts, so that the dirt and debris fall into the water. After the flotation is completed, the air pump 3 is turned off and the bolts and nuts fixing the top cover 7 are removed, and then the top cover 7 is lifted and the stirring shaft 9 is pulled out to expose the unqualified nuts floating on the water surface. At this time, the staff can fish out the unqualified nuts. After they are completely fished out, Re-fix the top cover 7 to the top of the body 1, then open the electromagnetic control valve of the discharge pipe 16, and the qualified nuts and sewage can be discharged into the receiving box 5 through the discharge pipe 16. After the discharge is completed, close the electromagnetic valve of the discharge pipe 16. At this time, start the water pump 4, and the water pipe 10 and the drain pipe 11 can be coordinated to introduce the sewage into the circulation box 2, so as to use the first filter 12, the second filter 13 and the third filter 14 inside the circulation box 2 to perform triple filtration on the sewage to fully remove the dirt and debris in the sewage, and finally re-introduce the purified water into the body 1 through the outlet pipe 15 for recycling. Finally, the qualified nuts will stay in the receiving box 5, waiting to be taken out by the staff.
