Description

Technical Field

[0001] The utility model relates to the technical field of glass recycling, in particular to a wind selection device for broken glass sundries. Background Technique

[0002] Glass is an amorphous inorganic non-metallic material, generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, and a small amount of auxiliary raw materials are added additionally. Its main components are silicon dioxide and other oxides. With the development of the industrialization process, the consumption and waste volume of glass products increase year by year. A large number of waste glass products are easy to pollute the environment and cannot be treated by burning and landfill methods. Only the method of recycling can be used to treat waste glass products. Glass recycling refers to the recycling of old glass bottles in order to achieve sustainable development. It can save expenses and better deal with the harm of garbage to nature. After the broken glass materials are recycled, they are good materials for producing glass microspheres, glass mosaics, colored glass balls, glass surfaces, glass bricks, artificial glass marbles, foam glass, etc. After the waste glass products are crushed, there will be a large number of impurities in the broken glass, such as light impurities such as foam, dust, wood chips, waste plastics, etc. The light sundries are generally screened by the method of wind selection.

[0003] For example, a wind selection device for broken glass sundries (publication number: CN209985779U), including a machine body and a feed hopper. A conveyor belt is arranged at the bottom of the machine body. A wind selection mechanism and a waste discharge port are arranged on the machine body. The wind selection mechanism and the waste discharge port are located on both sides of the machine body and the positions of the wind selection mechanism and the waste discharge port correspond to each other. The wind selection mechanism includes a motor, a fixing plate, a swing mechanism A, a swing mechanism B and a blowing mechanism. The fixing plate is arranged on the machine body. A motor is arranged on the fixing plate. One end of the motor is connected to one end of the swing mechanism A. The other end of the swing mechanism A is connected to the swing mechanism B. The swing mechanism A and the swing mechanism B have the same structure and each is connected to a blowing mechanism.

[0004] However, the device still has the following defects:

[0005] In the above device, the impurities in the broken glass are blown out from the waste discharge port and fall into the waste hopper through the blowing mechanism. However, in actual use, due to the different weights of the impurities, some light impurities are difficult to accurately fall into the waste hopper after being blown out from the waste discharge port, which not only affects the collection effect of the impurities, but also pollutes the environment of the working workshop. Content of the Utility Model

[0006] The purpose of the utility model is to provide a wind selection device for broken glass sundries. Through the cooperation of a shielding box and a waste box, the waste discharge port is shielded, so that the impurities blown out from the waste discharge port fall into the waste box, which is beneficial to the effective collection of the impurities. The installation is simple and has strong practicability.

[0007] To achieve the above object, the present utility model provides the following technical solutions: A wind separation device for broken glass and sundries, comprising a mounting frame, and a feed hopper fixedly connected to the upper surface of the mounting frame and communicating therewith, wherein a waste discharge port is penetrated through the side wall of the mounting frame; a conveyor belt, which is arranged in the mounting frame and used for conveying broken glass; a blowing mechanism, which is installed in the mounting frame and used for blowing air on the broken glass entering from the feed hopper; a waste box, which is arranged on one side of the mounting frame close to the waste discharge port, and a plurality of universal wheels are arranged at the bottom of the waste box; further comprising a mask box, which is hinged to the side wall of the waste box, and both the bottom of the mask box and the side wall of the mask box close to the mounting frame are open, a plug-in block is fixed to the top of the mask box, a fixing block is fixed to the side wall of the mounting frame, and a plug-in groove for plugging and matching with the plug-in block is opened at the intersection between the bottom and the side wall of the fixing block.

[0008] Preferably, the blowing mechanism comprises a mounting plate, which is fixed to the inner wall of the mounting frame on the side far from the waste discharge port; further comprising a blower fixed to the upper surface of the mounting plate and an expansion air duct fixed to the air outlet of the blower.

[0009] Preferably, both the blower and the expansion air duct are provided with two, and the two expansion air ducts are symmetrically arranged towards the middle of the waste discharge port.

[0010] Preferably, a limiting air duct is fixed to the end of the expansion air duct far from the blower.

[0011] Preferably, a wind shield is arranged on the inner top wall of the mounting frame close to the feed hopper.

Detailed Description of the Preferred Embodiments

[0021] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. The following describes each embodiment of the present utility model in detail with reference to the drawings.

[0022] Please refer to Figures 1 to 3 , the present utility model preferably provides a technical solution: a wind selection device for broken glass and sundries, including a mounting frame 1, and a feed hopper 2 fixedly connected and communicated with the upper surface of the mounting frame 1, and a waste discharge port 101 is penetrated and opened on the side wall of the mounting frame 1; a conveyor belt 3, the conveyor belt 3 is arranged in the mounting frame 1 and is used for conveying broken glass; a blowing mechanism 4, the blowing mechanism 4 is installed in the mounting frame 1 and is used for blowing the broken glass entering from the feed hopper 2; a waste box 5, the waste box 5 is arranged on one side of the mounting frame 1 close to the waste discharge port 101, and a plurality of universal wheels 6 are arranged at the bottom of the waste box 5; and further includes a mask box 7, the mask box 7 is hinged on the side wall of the waste box 5, both the bottom of the mask box 7 and the side wall of the mask box 7 close to the mounting frame 1 are open, an insertion block 8 is fixed on the top of the mask box 7, a fixing block 9 is fixed on the side wall of the mounting frame 1, and an insertion slot 91 that is in insertion fit with the insertion block 8 is opened at the intersection of the bottom and the side wall of the fixing block 9.

[0023] In this embodiment, the waste box 5 is arranged on the side of the mounting frame 1 close to the waste discharge port 101. The insertion block 8 is inserted into the insertion groove 91, so that the side wall of the mask box 7 is closely attached to the side wall of the mounting frame 1 and covers the waste discharge port 101. Broken glass is put into the mounting frame 1 through the feed hopper 2 and falls on the conveyor belt 3. During this process, the blowing mechanism 4 blows away the impurities in the broken glass during the falling process and blows them out of the mounting frame 1 through the waste discharge port 101. The blown impurities are blocked by the mask box 7 and fall into the waste box 5, reducing the probability that the impurities fly around after being blown out and polluting the working environment, and improving the collection effect of the impurities.

[0024] Further, the blowing mechanism 4 includes a mounting plate 41, and the mounting plate 41 is fixed on the inner wall of the mounting frame 1 on the side far from the waste discharge port 101; it also includes a blower 42 fixed on the upper surface of the mounting plate 41 and an expansion air duct 43 fixed to the air outlet of the blower 42.

[0025] As Figures 1 to 3 shown, by starting the blower 42, the air is blown from the expansion air duct 43 towards the waste discharge port 101, so as to blow out the impurities in the broken glass entering through the feed hopper 2.

[0026] Further, both the blower 42 and the expansion air duct 43 are provided with two. The two expansion air ducts 43 are symmetrically arranged towards the middle of the waste discharge port 101. As Figure 1 shown, the two blowers 42 and the expansion air ducts 43 blow the broken glass entering through the feed hopper 2 from both sides, and blow towards the middle of the waste discharge port 101 from both sides, improving the air separation effect on the broken glass.

[0027] Further, a wind limiting duct 10 is fixed at the end of the expansion air duct 43 far from the blower 42. As Figure 1 、 2 shown, the wind limiting duct 10 plays a role in restricting the air blown out from the expansion air duct 43, reducing the probability that the expansion air duct 43 blows the impurities in the broken glass to the surrounding.

[0028] Further, a wind shield 11 is arranged on the inner top wall of the mounting frame 1 close to the feed hopper 2. As Figure 1 、 2 shown, the wind shield 11 plays a role in protecting the broken glass entering from the feed hopper 2, reducing the probability that the wind generated by the blowing mechanism 4 affects the vertical falling of the broken glass.

[0029] Further, an arc-shaped plate 12 is fixed on the inner wall of the mask box 7. As Figure 2 shown, the arc-shaped plate 12 plays a guiding role for the impurities blown towards the mask box 7, which is beneficial for the impurities to fall into the waste box 5 along the arc-shaped plate 12 downward.

[0030] Further, an upper magnetic block 13 is embedded in the inner top wall of the insertion slot 91, and a lower magnetic block 14 magnetically attracted to the upper magnetic block 13 is embedded in the upper surface of the insertion block 88. As Figure 2 shown, the upper magnetic block 13 and the lower magnetic block 14 are magnetically attracted to each other, fixing the insertion block 8 in the insertion slot 91, reducing the probability of the insertion block 8 detaching from the insertion slot 91, and enhancing the stability of the shielding box 7.

[0031] Further, an opening is provided on the side wall of the waste box 5, and a baffle 15 for closing the opening of the waste box 5 is hinged on the side wall of the waste box 5. As Figure 1 shown, after the air separation is completed, the staff can open the waste box 5 by opening the baffle 15, facilitating the cleaning of the impurities in the waste box 5.

[0032] In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "connection", "fixation" and the like shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated. There are various detachable installation methods. For example, it can be by means of cooperation between insertion and snap, or by means of bolt connection, etc.

[0033] The above embodiments' specific description of the present utility model is only for further explaining the present utility model and cannot be understood as a limitation on the protection scope of the present utility model. Any non-essential improvements and adjustments made by those skilled in the art based on the content of the above utility model fall within the protection scope of the present utility model.
