Description

Technical Field

[0001] This utility model relates to the field of filter material waste processing technology, and in particular to a waste crusher. Background Technology

[0002] Waste shredders are key pieces of equipment in the industrial field for processing various types of waste, especially widely used in the crushing and recycling of textile waste such as fiberglass filter cloth and non-woven filter cotton. These devices typically include a feed inlet, a crushing chamber, and a discharge outlet. During operation, the waste is fed into the crushing chamber through the feed inlet, where it is crushed by blades or hammers into fiber fragments or particles, which are then discharged through the discharge outlet.

[0003] However, existing waste shredders have significant drawbacks in practical use. Because the shredding process typically involves high-speed rotation and airflow turbulence, some of the crushed lightweight materials, such as fiber fragments and dust, are easily ejected backwards from the feed inlet, causing material splashing and accumulation, severely impacting the cleanliness and safety of the operating area. Simultaneously, during the discharge process, fine fibers and dust easily disperse into the air, leading to increased concentrations of suspended particulate matter in the working environment. This not only pollutes air quality but may also pose potential health hazards to operators and reduce the overall efficiency of waste recycling.

[0004] Most ordinary crushers currently on the market are not effectively designed to address the aforementioned problems, especially lacking reliable sealing and dust control structures. Therefore, there is an urgent need for a waste crusher that can effectively prevent material splashing and dust escape during the crushing process, in order to improve the quality of the working environment and the efficiency of equipment use. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a waste crusher, which solves the problems of material splashing and dust escape during the crushing process of waste in the existing technology.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A waste shredder includes a shredder body, a feed pipe, and a discharge pipe. The feed pipe is an open mechanism facing an upward angle, with a feed inlet at its end. A closing mechanism is provided at the feed inlet, comprising a rotating shaft, a closing baffle, and a bottom baffle. The rotating shaft is horizontally rotatably mounted on the inner wall of the feed pipe above the feed inlet. The closing baffle is fixedly mounted on the side wall of the rotating shaft and swings with the rotation of the rotating shaft. The bottom baffle is vertically disposed at the lower part of the feed inlet. When the closing baffle hangs freely, its bottom end abuts against the inner side of the bottom baffle, together closing the feed inlet.

[0008] Furthermore, the enclosed baffle includes a baffle frame and an enclosed partition. The baffle frame is fixedly connected to the rotating shaft, and the interior of the baffle frame has a cavity. The enclosed partition is installed in the cavity inside the baffle frame.

[0009] Furthermore, the baffle frame is provided with a scraper mechanism, which includes a brush plate, bristles, and a connecting rod; the two vertical side plates of the baffle frame are provided with parallel sliding grooves; the two brush plates are connected by the connecting rod, which is housed in the sliding groove, so that the two brush plates can move along the length of the baffle frame; the bristles are provided on the side of the brush plate facing the closed partition and are in contact with the surface of the closed partition.

[0010] Furthermore, the scraper mechanism also includes a handle for manually pushing the brush plate, the handle being mounted on the outer side of the brush plate.

[0011] Furthermore, the bottom baffle is made of iron, and a groove is provided at the lower end of the baffle frame, in which a magnetic strip is fixed; when the closed baffle is lowered, the magnetic strip is attracted to the bottom baffle.

[0012] Furthermore, a fan is installed on the side of the bottom baffle facing the inside of the feed pipe, and the airflow direction of the fan is towards the inside of the feed pipe.

[0013] Furthermore, a protective mesh cover is provided on the outside of the fan.

[0014] Furthermore, a slot is provided on the side of the feed pipe near the main body of the crusher, and a push-pull baffle is inserted into the slot to control the connection between the feed pipe and the inside of the crusher body.

[0015] This utility model has the following beneficial effects: By setting a dynamically openable and closable closed baffle mechanism at the feed inlet and cooperating with the bottom fan to blow air inward, this solution effectively prevents material splashing and dust escape during the crushing process, significantly improving the working environment and air quality; at the same time, its scraper mechanism can remove adsorbed debris, reducing the frequency of manual cleaning, thereby ensuring efficient and continuous production while improving the equipment's sealing performance, environmental friendliness, and ease of operation.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] A type of waste shredder, such as Figure 1-4 As shown, the device includes a crusher body 1, a feed pipe 2, and a discharge pipe 3. The feed pipe 2 is an open mechanism facing an upward angle, and a feed inlet 4 is provided at the end of the feed pipe 2 away from the crusher body 1. The end face of the feed inlet 4 is located in a vertical plane.

[0023] In this embodiment, the feed pipe 2 is a tubular structure with a square cross-section and is made of iron. A horizontal rotating shaft 5 is rotatably installed on the inner wall of the feed pipe 2 at the upper part of the feed inlet 4. A sealing baffle is fixedly installed on the side wall of the rotating shaft 5 along its length. The sealing baffle swings as the rotating shaft 5 rotates. When the sealing baffle hangs freely under its own weight, it fills and blocks the passage of the feed inlet 4.

[0024] The enclosed baffle includes a baffle frame 6, which can be made of various materials; in this embodiment, it is made of plastic. The baffle frame 6 is fixedly connected to the side wall of the rotating shaft 5, and the width of the baffle frame 6 is the same as the length of the rotating shaft 5. The baffle frame 6 is square, and there are square openings inside the baffle frame 6. Enclosed partitions 7 are installed in the square openings. The enclosed partitions 7 can be made of either polyethylene or polyvinyl chloride and are attached to the baffle frame 6. A scraper mechanism is also provided on the baffle frame 6. The scraper mechanism moves back and forth along the length of the two vertical side plates of the baffle frame 6 to clean the dust or material debris adsorbed on the enclosed partitions 7.

[0025] The scraper mechanism includes two opposing brush plates 8, two brush bristles 9, and connecting rods 10. Parallel grooves 11 are provided on the two vertical side plates of the baffle frame 6. The two brush plates 8 are located on opposite sides of the baffle frame 6 and are fixedly connected by two connecting rods 10, which are located within the two grooves 11. The two brush bristles 9 are located on opposite sides of the two brush plates 8, with the end of the brush bristle 9 away from the brush plate 8 contacting the enclosed partition 7. A handle 12 for the operator to push the scraper mechanism is also installed on the outer brush plate 8. To improve sealing performance, two rubber strips can be installed within the grooves 11 to cover them, and the connecting rods 10 can pass between the two rubber strips.

[0026] A bottom baffle 13 is provided at the lower part of the feed inlet 4. The bottom baffle 13 is vertically arranged. When the closed baffle hangs freely under its own weight, the bottom end of the closed baffle abuts against the inner side of the bottom baffle 13. A groove is provided at the lower end of the baffle frame 6. A magnetic strip 14 is fixed in the groove and is used to attract the bottom baffle 13.

[0027] A fan 15 is also installed on the side of the bottom baffle 13 facing the inside of the feed pipe 2, and the airflow of the fan 15 is directed towards the inside of the feed pipe 2. A mesh cover 16 is provided on the outside of the fan 15. When the fan 15 is started, the airflow generated can blow the debris and dust produced by the equipment into the feed pipe 2, and at the same time, it also helps to blow the waste material fed into the feed pipe 2 into the crusher body 1.

[0028] A slot is provided on the side of the feed pipe 2 near the main body 1 of the crusher, and a baffle plate 17 is inserted in the slot. The baffle plate 17 is pushed and pulled along the slot to control the internal conduction or closure of the feed pipe 2.

[0029] In operation, the operator simply inserts waste materials, such as waste fiberglass filter cloth or waste non-woven filter bags, into the feed inlet 4. The waste material presses against the sealing baffle and pushes it open further, creating an opening at the bottom of the sealing baffle away from the bottom baffle 13. The waste material is then pushed into the feed pipe 2 through this opening. During this process, the blower 15 can be turned on as needed to assist the waste material in falling. The resulting airflow is also located at the opening and directed towards the inside of the feed pipe 2, preventing dust or debris from escaping from this opening. Once the waste material has completely fallen into the feed pipe 2, the sealing baffle returns to its original position under its own weight, thus closing the feed inlet 4 again. After prolonged processing, dust and waste material will adhere to the sealing partition 7. At this time, the scraper mechanism can be used to clean the sealing partition 7. Meanwhile, after the brush bristles 9 brush over the closed partition 7, in addition to cleaning the partition 7, they also improve its electrostatic adsorption capacity, increasing its ability to adsorb dust and further preventing dust from escaping from the feed inlet 4. When the blower 15 is turned on, the baffle plate 17 is in the pulled-out state, at which time the feed pipe 2 is in a conductive state with the inside of the crusher body 1. When the baffle plate 17 is in the pushed-in state, the blower 15 needs to be turned off.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
