Description

Technical Field

[0001] The utility model relates to the technical field of color sorter components, in particular to an air intake structure for a color sorter. Background Art

[0002] Color sorter is a device that uses photoelectric detection technology to automatically sort out different-colored particles in granular materials based on the differences in the optical properties of the materials. Color sorter is often used in the fields of bulk materials or packaging industrial products, and food quality inspection and grading.

[0003] At present, the traditional inclined plate color sorter has only two sets of air intake units. The output of the two sets of air intake units is filled into the air storage bag, and all the air-consuming components of the equipment are discharged from the air storage bag.

[0004] However, during color sorting, all gas-consuming units in the equipment use gas at the same time. This situation will cause the gas pressure in the gas storage bag to be too low, so that the high-pressure gas pressure ejected from the air nozzle is insufficient, and the separation operation cannot be performed accurately. For this reason, an air intake structure for a color sorter is proposed. Utility Model Content

[0005] The utility model aims to provide an air intake structure for a color sorter, so as to solve the problem in the prior art that the air components in the existing color sorter are all taken from the air storage bag, resulting in insufficient pressure of the high-pressure gas ejected from the air nozzle, thus affecting the separation operation.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an air intake structure for a color sorter, used for a color sorter, comprising an air storage bag placed inside the color sorter, the air storage bag being connected to two three-way pipes, the other two interfaces of the three-way pipes being placed outside the color sorter, the other two interfaces of the three-way pipes being fixedly connected to an air intake unit, the front end pipelines of the air intake unit being connected to connecting pipes, the side walls of the connecting pipes being fixedly connected to side pipes, for providing required gas to other gas-using components in the color sorter except for the air nozzle.

[0007] Preferably: both ends of the connecting pipe and the end of the side pipe away from the connecting pipe are fixedly connected with connecting parts for connecting and fixing the air compressor pipeline, the front end pipeline of the air intake unit and the front end pipelines of other air-using components except the air nozzle.

[0008] Preferably, the connecting piece comprises a sleeve fixedly connected to both ends of the connecting pipe and an end of the side pipe away from the connecting pipe, and a sleeve opening is fixedly connected to the end of the sleeve, and the sleeve opening is elastic.

[0009] Preferably, the front end pipeline of the air intake unit is inserted into the connecting pipe, and the air compressor pipeline is inserted into the connecting pipe.

[0010] Preferably, the outer wall of the front end pipeline of the air intake unit fits with the inner wall of the connecting pipe, and the outer wall of the air compressor pipeline fits with the inner wall of the connecting pipe.

[0011] Preferably, the wrapping sleeve is elastic, and the wrapping sleeve and the sleeve opening are both made of rubber.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. Through the setting and cooperation of the three-way pipe, the air intake unit and the connecting pipe, it can avoid the insufficient air pressure of the air storage bag caused by all the air-consuming components taking air from the air storage bag, improve the separation efficiency, and also make the gas required by other air-consuming components in the color sorter that do not need to be processed by the air intake unit directly connected to the gas from the side pipe, reducing the excessive use of the air intake unit and prolonging its service life. The structure is simple and efficient, suitable for popularization.

[0014] 2. Through the setting and cooperation of the wrapping sleeve and the sleeve mouth, the elasticity of the sleeve mouth is utilized to make the connection and fixation easier and convenient to disassemble. At the same time, when the pressure of the gas ejected from the air compressor pipeline is too high or the air storage bag has reached the gas storage threshold, the sleeve mouth will slide against the front end pipeline of the air intake unit, the air compressor pipeline and the outer wall of the front end pipeline of other gas components except the air nozzle until they are separated from each other, thereby protecting the safety of the gas components inside the color sorter. The structure is simple and efficient, suitable for popularization and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 The utility model provides a technical solution for the air intake structure of a color sorter:

[0022] A color sorter air intake structure is used for the color sorter 1, including an air storage bag 101 placed inside the color sorter 1, the air storage bag 101 is connected to two three-way pipes 2, the other two interfaces of the three-way pipes 2 are placed outside the color sorter 1, the other two interfaces of the three-way pipes 2 are fixedly connected to an air intake unit 3, the front end pipeline of the air intake unit 3 is connected to a connecting pipe 4, the side wall of the connecting pipe 4 is fixedly connected to a side pipe 401, which is used to provide required gas to other gas-using components in the color sorter 1 except the air nozzle, wherein it needs to be supplemented that the air intake unit 3 is a prior art, which is used to filter the gas and other operations to meet the gas use requirements, and will not be elaborated on here.

[0023] Through the arrangement and cooperation of the three-way pipe 2, the air intake unit 3 and the connecting pipe 4, insufficient air pressure in the air storage bag 101 caused by all air-consuming components being taken from the air storage bag 101 is avoided, thereby improving the separation efficiency. In addition, the gas required by other air-consuming components in the color sorter 1 that do not need to be processed by the air intake unit 3 is directly connected to the gas from the side pipe 401, thereby reducing excessive use of the air intake unit 3 and increasing its service life. The structural arrangement is simple and efficient, and is suitable for popularization and use.

[0024] Both ends of the connecting pipe 4 and the end of the side pipe 401 away from the connecting pipe 4 are fixedly connected with connecting parts 402, which are used to connect and fix the air compressor pipeline connected thereto, the front pipeline of the air intake unit 3 and the front pipelines of other air-using components except the air nozzle.

[0025] Among them, it should be supplemented that the connecting piece 402 includes a wrapping sleeve 403 fixedly connected to the two ends of the connecting pipe 4 and the end of the side pipe 401 away from the connecting pipe 4, and a sleeve mouth 404 is fixedly connected to the port of the wrapping sleeve 403. The sleeve mouth 404 is elastic and the wrapping sleeve 403 is elastic and is used to wrap pipes of different sizes. The materials of the wrapping sleeve 403 and the sleeve mouth 404 are both rubber.

[0026] By setting and cooperating with the wrapping sleeve 403 and the sleeve opening 404, the elasticity of the sleeve opening 404 is utilized to make the connection and fixation easier and convenient for disassembly. When the pressure of the gas ejected from the air compressor pipeline is too high or the air storage bag 101 has reached the air storage threshold, the sleeve opening 404 will slide against the outer wall of the front end pipeline of the air intake unit 3, the air compressor pipeline and the front end pipeline of other air-using components except the air nozzle until they are separated from each other, thereby protecting the safety of the air-using components inside the color sorter 1. The structural setting is simple and efficient, and is suitable for popularization and use.

[0027] Among them, it should be supplemented that the front end pipeline of the air intake unit 3 is inserted into the connecting pipe 4, the air compressor pipeline is inserted into the connecting pipe 4, the outer wall of the front end pipeline of the air intake unit 3 and the inner wall of the connecting pipe 4 are fitted, and the outer wall of the air compressor pipeline and the inner wall of the connecting pipe 4 are fitted. Such an arrangement is conducive to more convenient installation.

[0028] Working principle: through the arrangement and cooperation of the three-way pipe 2, the air inlet unit 3 and the connecting pipe 4, the air storage bag 101 is fully used for the air nozzle, and other air-using components in the color sorter 1 obtain gas through the connecting pipe 4 and the side pipe 401, which not only avoids the insufficient air pressure of the air storage bag 101 caused by all air-using components taking air from the air storage bag 101, so that the high-pressure gas pressure ejected from the air nozzle is insufficient, thereby failing to accurately perform the separation operation, but also enables the gas required by other air-using components in the color sorter 1 that do not need to be processed by the air inlet unit 3 to be directly connected to the gas from the side pipe 401, thereby reducing the excessive use of the air inlet unit 3 and prolonging its service life. The structure is simple and efficient, and is suitable for popularization and use.

[0029] By setting and cooperating with the wrapping sleeve 403 and the sleeve opening 404, the elasticity of the sleeve opening 404 is utilized, so that the connecting pipe 4 and the side pipe 401 are quickly connected and fixed with the front end pipeline of the air intake unit 3, the air compressor pipeline and the front end pipelines of other air-using components except the air nozzle, and are easy to disassemble. At the same time, since the connecting pipe 4, the side pipe 401 and the front end pipeline of the air intake unit 3, the air compressor pipeline and the front end pipelines of other air-using components except the air nozzle are not locked, when the pressure of the gas ejected from the air compressor pipeline is too high or the air storage bag 101 has reached the air storage threshold, the sleeve opening 404 will slide against the outer wall of the front end pipeline of the air intake unit 3, the air compressor pipeline and the front end pipelines of other air-using components except the air nozzle until they are separated from each other, thereby avoiding the air-using components inside the color sorter 1 from being damaged by high pressure, protecting its safety, and the structural setting is simple and efficient, suitable for popularization and use.
