Description

Technical Field

[0001] The utility model relates to the technical field of nozzle equipment, in particular to a compact nozzle device and a rice color sorter using the same. Background Art

[0002] The nozzle device uses compressed gas as a power to blow the target object to move, or uses compressed gas to flow through a narrow nozzle at high speed to create a low-pressure area, sucking out liquid or powder, and evenly distributing it in the target space in the form of tiny droplets or uniform powder dispersion with the high-speed airflow, realizing application scenarios such as atomization. The nozzle device is widely used in pharmaceutical, food processing, food drying, cutting processing in industrial fields, product surface polishing, surface spraying, etc., and has a very broad application prospect.

[0003] At present, air pumps are basically used to compress air, and multi-channel air valves are used to distribute high-pressure air. The high-pressure air is sent to the nozzle through quick-plug interfaces and air pipes to achieve functions such as blowing objects, atomizing liquids or powders, and polishing or spraying product surfaces.

[0004] In this scheme, except for the air pump and oil-water separator, the multi-channel air valve, nozzle and air pipe are all separate components. Although they can complete the required functions, in a system with more nozzles, multiple multi-channel air valves need to be separately arranged and installed. For more nozzles, installation gaps need to be left between each air valve and nozzle to facilitate the installation of the air valve and nozzle. This requires a larger installation space, which is not conducive to the miniaturization of the equipment. Each air valve channel and nozzle need to be connected to an air pipe, resulting in the air valve and nozzle installation area being full of air pipes, which is not conducive to troubleshooting and maintenance. In addition, a quick-connect connector is used to connect the air pipe between each air valve channel and the nozzle, which is prone to leakage due to the deviation of the air pipe insertion depth, causing insufficient pressure or flow rate at the nozzle output port, causing failure. The deviation between the inner diameter of the air pipe and the inner diameter of the quick-connect connector, or the failure of the air pipe to be inserted in place causes a sudden change in the cross-sectional size of the channel through which the compressed air flows, thereby causing turbulence in the air flow, which can generate noise, consume the energy of the compressed air, reduce the compressed air flow rate, and thus reduce the efficiency of the equipment. Summary of the invention

[0005] The purpose of the utility model is to overcome the deficiencies in the above-mentioned prior art and to provide a compact nozzle device and a rice color sorter using the same. The compact nozzle device eliminates the large amount of air pipes used in the traditional method, the air path is more optimized, and a fixing method of inclined step support is adopted to facilitate height adjustment and more accurate nozzle positioning.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a compact nozzle device, including a multi-channel air valve and an integrated nozzle component, the bottom surface of the integrated nozzle component is a mounting surface, which is used to install and fix a plurality of multi-channel air valves, and a plurality of fixing areas are provided on the mounting surface, each fixing area is provided with an air inlet hole and a fixing threaded hole corresponding to the multi-channel air valve, a plurality of nozzles are neatly arranged on the top surface of the integrated nozzle component, an independent air channel is provided inside the integrated nozzle component corresponding to each air inlet hole to each nozzle, a slope step is provided on the side of the integrated nozzle component, and the slope is parallel to the air outlet direction of the nozzle, the integrated nozzle component is supported on the frame by the slope step, and can slide along the slope step to facilitate the adjustment of the nozzle height, and the height is fixed after it is determined.

[0007] In the above technical solution, the multi-channel gas valve is installed vertically upward, with a reasonable layout, and does not affect other components of the equipment.

[0008] In the above technical solution, the air passage is generated in the integrated nozzle component by mechanical processing.

[0009] In the above technical solution, the integrated nozzle component is manufactured using a metal triangular bar as a base material, and other suitable materials may also be selected. In general industrial environments, it is recommended to use an aluminum triangular bar for manufacturing. For the convenience of description, including the following text, it is assumed that it is manufactured using an aluminum triangular bar. The corresponding nozzles are processed on the top surface of the aluminum triangular bar according to the equipment's requirements for the density of the arrangement of the high-pressure gas nozzles, and the corresponding air channels are processed on the bottom surface of the aluminum triangular bar according to the position and diameter of the multi-channel air valve air channel, and connected with the corresponding nozzles on the corresponding top surface of the aluminum triangular bar to form an integrated nozzle component. According to the installation hole position of the multi-channel air valve, threaded holes are processed at the corresponding positions on the bottom surface of the aluminum triangular bar, and the multi-channel air valve is reliably fixed to the integrated nozzle component by screws to form a compact nozzle device.

[0010] In the above technical solution, the mounting hole (groove) is processed according to the installation position and installation method of the integrated nozzle component on the equipment on which it is used, and the integrated nozzle component is supported on the frame through an inclined step, and the height is adjusted. After the height is determined, it is fixed by screws.

[0011] In the above technical solution, according to the equipment's requirement for the number of nozzles, multiple multi-channel air valves can be arranged on the integrated nozzle component to meet the requirement for the number of nozzles. This can effectively reduce the installation space and facilitate the miniaturization of the equipment.

[0012] The compact nozzle device can arrange the nozzles in a straight line on one side of the top surface of the aluminum triangle rod according to the equipment use requirements.

[0013] The utility model also provides a rice color sorter, comprising the above-mentioned compact nozzle device.

[0014] Compared with the prior art, the compact nozzle device of the utility model has the following advantages:

[0015] 1. The layout is suitable for grain machinery, rice color sorter, etc. The multi-channel air valve is inverted upward, the air path is short and the consistency is good.

[0016] 2. The inclined step support method facilitates height adjustment and makes nozzle positioning more accurate.

[0017] 3.

At the same time, it is easy to connect and install with the multi-channel air valve, which improves the reliability of the air path. BRIEF DESCRIPTION OF THE DRAWINGS
