[0031] In the related art, the silo usually needs to replace different materials according to the production or storage needs during use. Specifically, a dryer is a device that dries or removes small molecules from materials by introducing hot air. It is widely used in the plastic processing industry, such as polypropylene, polyamide 12, etc. To meet customer needs, the dryer needs to dry and remove moisture before packaging and sending to customers for application.

[0032] However, due to the variety of drying plastic types, grades, and colors, switching is relatively frequent, and in order to avoid quality problems, the observation port of the dryer feeding bin needs to be opened during product switching, and a cloth and an air gun are used for cleaning. The entire cleaning process is time-consuming and requires a waste of manpower, affecting the use efficiency of the equipment.

[0033] The embodiments of the present application will be described below in conjunction with Figures 1 to 2 .

[0034] According to the embodiments of the present application, in one aspect, a feeding bin is provided, as shown in Figure 1 , comprising a bin body 1 and a cleaning nozzle 2, and the specific scheme is as follows.

[0035] As shown in Figure 1 , the bin body 1 is provided with a material cavity 101 for accommodating material. Specifically, the bin body 1 can be of any shape, such as a cylindrical shape, a rectangular cylindrical shape, etc. The bin body 1 can be a metal shell, such as an iron shell, an aluminum shell, an aluminum alloy shell, etc. Of course, the shape and material of the bin body 1 can be selected and set according to industrial needs.

[0036] As shown in Figure 1 and Figure 2 , the cleaning nozzle 2 is provided with a plurality of cleaning nozzles 2, which are located in the material cavity 101 and connected with the inner wall surface of the material cavity 101. The cleaning nozzle 2 is provided with a plurality of spray holes 201, and the direction of at least a part of the spray holes 201 can be changed.

[0037] It should be explained that the direction of at least a part of the spray holes 201 can be changed, which means that the direction of a part of the spray holes 201 can be changed, or the direction of all the spray holes 201 can be changed. The way of changing the direction of the spray holes 201 can be changing the direction of the spray holes 201 relative to the cleaning nozzle 2, or changing the relative position of the cleaning nozzle 2 relative to the material cavity 101 to change the direction of the spray holes 201, or other ways of changing the direction of the spray holes 201.

[0038] It should be further explained that the cleaning nozzle 2 can be used to spray high-pressure gas to clean the wall surface of the material cavity 101, i.e., the cleaning nozzle 2 is a gas nozzle; or it can spray high-pressure cleaning liquid to clean the wall surface of the material cavity 101, which can be selected according to the cleaning needs, i.e., the cleaning nozzle 2 is a liquid nozzle.

[0039] Specifically, as shown in Figure 2As shown, the cleaning nozzle 2 can adopt a honeycomb design, that is, a plurality of spray holes 201 are arranged in a honeycomb shape on the outer surface of the cleaning nozzle 2, that is, the spray holes 201 are irregularly arranged; the shape of the cleaning nozzle 2 can be any shape such as a circle, an ellipse, a square, etc., and is preferably a circle or an ellipse, the overall size of the outline is between 50mm and 100mm, the cleaning nozzle 2 is a metal nozzle, and is preferably any one of a 304 stainless steel nozzle, a 316 stainless steel nozzle, and a 316L stainless steel nozzle; the number of the spray holes 201 is 6-12, and is preferably any one of 6, 8, 10, and 12, and is preferably 12; the diameter of the spray hole 201 is 2mm-4mm, and is preferably any one of 2mm, 3mm, and 4mm, and is preferably 3mm.

[0040] In the specific use process, as shown in Figure 1 As shown, before switching the material in the bin, high-pressure gas (such as high-pressure air) or high-pressure cleaning liquid (such as water) is injected into the cleaning nozzle 2, because the direction of the spray holes 201 on the cleaning nozzle 2 can be changed, the direction of the high-pressure gas or high-pressure liquid sprayed from the spray holes 201 is uncertain, more parts in the material cavity 101 can be considered, the cleaning nozzle 2 can clean a larger area in the material cavity 101, and dead angles are avoided.

[0041] In this embodiment, as shown in Figure 1 A plurality of cleaning nozzles are arranged in the material cavity 101, a plurality of spray holes 201 are arranged on the cleaning nozzle, and the direction of at least part of the spray holes 201 can be changed, so that the direction of the high-pressure gas or high-pressure liquid sprayed from the spray holes 201 is uncertain, more parts in the material cavity 101 can be considered, the cleaning nozzle 2 can clean a larger area in the material cavity 101, and dead angles are avoided, so that the material cavity 101 can be quickly and comprehensively cleaned, the cleaning time is shortened, the use efficiency of the bin is improved, and the cleaning cleanliness is improved.

[0042] In one embodiment, as shown in Figure 1 The cleaning nozzle 2 is rotationally connected with the inner wall surface of the material cavity 101, specifically, the input end of the cleaning nozzle 2 can be rotationally connected with the wall surface of the material cavity 101 through a sealing bearing, can be rotationally connected with the wall surface of the material cavity 101 through a bearing bush, or can be rotationally connected with the wall surface of the material cavity 101 through other ways.

[0043] In this embodiment, the cleaning nozzle 2 is rotationally connected with the wall surface of the material cavity 101, so that the cleaning nozzle 2 can rotate to change the direction of the spray holes 201 on the cleaning nozzle 2, so that the cleaning nozzle 2 can clean more parts of the material cavity 101, this way is simple, stable in operation, and long in service life.

[0044] In some not shown embodiments, the cleaning nozzle 2 can be connected with the wall of the material cavity 101 through a hose. Specifically, the hose can be a rubber tube or a silica gel tube, etc. which can be flexibly bent under external force. Of course, the cleaning nozzle 2 can also be a rubber nozzle, and the hose and the cleaning nozzle 2 can be integrally formed. An opening is arranged on the wall of the material cavity 101, and the hose is in communication with the opening on the material cavity 101 through interference fit.

[0045] In this embodiment, the cleaning nozzle 2 is connected with the material cavity 101 through the hose. The cleaning nozzle 2 is randomly shaken by the reaction force of the high-pressure gas or high-pressure cleaning liquid sprayed through the spray holes 201 of the cleaning nozzle 2, so as to change the orientation of the spray holes 201, so that the spray holes 201 can clean multiple parts of the material cavity 101, improve the cleaning efficiency, and avoid dead angles.

[0053] In this embodiment, as shown in Figure 2 the outlet of at least some of the spray holes 201 disposed on the circumferential side wall of the cleaning spray head 2 is disposed on a side different from the rotation axis of the cleaning spray head 2, so that the spray holes 201 can generate a thrust force along the circumference of the cleaning spray head 2 to drive the cleaning spray head 2 to rotate by itself.
