Description

Technical Field

[0001] This utility model relates to the technical field of waste material cutting equipment, and in particular to a waste material cutting equipment for the preparation of environmentally friendly building materials. Background Technology

[0002] The raw materials for environmentally friendly building materials typically include natural plant fibers such as straw, wood chips, and bamboo shavings; inorganic materials such as cement and gypsum; and recycled materials such as recycled steel and bamboo. Recycled steel significantly reduces energy consumption and carbon emissions during the production of new steel by reusing existing steel. Bamboo, due to its rapid growth and ease of reforestation, is considered a highly renewable resource suitable for various construction tasks. The preparation of environmentally friendly building materials inevitably generates some waste and scraps, which require cutting equipment for reuse.

[0003] Existing technologies for cutting environmentally friendly building materials have certain shortcomings. For example, dust is generated during the cutting process. Since users need to observe the operation of the equipment, dust leakage can affect their physical and mental health. Existing technologies only include so-called dust suppression devices during the cutting process, but this effect is unsatisfactory. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a waste cutting device for the preparation of environmentally friendly building materials, which has the advantages of effective dust reduction and secondary utilization of water resources, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a waste cutting device for the preparation of environmentally friendly building materials, comprising a box body, with an inlet and an outlet respectively opened on both sides of the box body, and dust baffles rotatably installed on both the inlet and outlet of the box body, conveying devices installed inside the box body at both the inlet and outlet, a water storage chamber opened inside the box body, a water collection tank opened between the inside of the box body and the water storage chamber, a filter plate movably installed inside the box body between the water storage chamber and the water collection tank, a variable frequency pump provided on one side of the box body, a cylinder fixedly installed on the top of the box body, and a pre-wetting rack and a cleaning rack respectively installed on both sides of the cylinder inside the box body.

[0006] Through the above structural setup, the dust baffle, dust suppression nozzles, pre-wetting rack, and washing rack work together to achieve a certain dust suppression effect. When the material passes through the pre-wetting rack, it is sprayed in multiple directions by the diffusion nozzles, so that the surface of the material is initially pre-wetted. During the cutting process, the dust suppression nozzles spray water, which has the effect of dust suppression and cooling during cutting. The side nozzles wash the surface of the material from two directions, washing away the remaining adhering dust and debris.

[0007] Preferably, the conveying device includes an infeed roller belt and an output roller belt. The infeed roller belt is rotatably installed inside the housing between the inlet and the outlet, and the output roller belt is rotatably installed inside the housing between the outlet and the outlet. There is a certain gap between the infeed roller belt and the output roller belt.

[0008] Preferably, the filter plate has two layers of placement slots inside, at the connection between the water storage chamber and the water collection tank. The upper placement slot is fixedly installed with a coarse-pore sponge, and the lower placement slot is fixedly installed with a fine-pore sponge. The pore diameter of the fine-pore sponge is smaller than that of the coarse-pore sponge.

[0009] With the above-mentioned structure, water mixed with dust and debris is collected in the water collection tank and then filtered by the water filter plate. The water filter plate performs dual filtration of water and impurities. First, the coarse-pore sponge blocks large particles of dust and debris on its surface. After the small particles of dust and water are filtered by the fine-pore sponge, the water flows through the fine-pore sponge into the water storage chamber, realizing the reuse of water resources.

[0010] Preferably, the variable frequency pump is connected to the inside of the water storage chamber, the variable frequency pump is located inside the housing and connected to a pump outlet pipe, and the pump outlet pipe is located inside the inner wall of the housing and connected to a dispersion pipe.

[0011] Preferably, a tool holder is fixedly connected inside the housing below the output shaft of the cylinder. The tool holder has a blade at its bottom and is positioned between the infeed roller belt and the output roller belt. Water pipes and dust suppression nozzles are installed on both sides of the middle part of the tool holder. The water pipes are connected to the dispersion pipe and the dust suppression nozzles. The dust suppression nozzles are fan-shaped nozzles, and the spray direction of the dust suppression nozzles is located at the end of the blade of the tool holder.

[0012] With the above structural design, the water sprayed from the dust suppression nozzle can be cooled in time when the blade holder is cutting, and the dust generated during cutting is also wetted by the water, preventing dust from flying and leaking out.

[0013] Preferably, the pre-wetting frame is installed on the feed inlet side of the box body and located on the outer ring of the feed roller belt. The inner surface of the pre-wetting frame is uniformly provided with spray holes in a linear array. A diffusion nozzle is fixedly installed inside the spray hole. The diffusion nozzle is embedded and is connected to the end of the dispersion tube.

[0014] With the above structural design, when the material is conveyed by the feed roller belt, the diffusion nozzle evenly wets the surface of the material, so that dust is generated as little as possible during processing, thus achieving the effect of dust reduction.

[0015] Preferably, the cleaning rack is installed on the discharge port side of the box and located on the outer ring of the output roller belt. A side nozzle is symmetrically installed on the bottom surface of the cleaning rack. The spray direction of the side nozzle is located on the surface of the output roller belt. The side nozzle is connected to the other end of the dispersion tube.

[0016] With the above-mentioned structure, the cleaning rack will continuously spray water from the dispersion pipe, and the material and surface will be washed by the two lateral water flows, causing dust particles and debris to be flushed out to both sides.

[0017] This utility model has the following advantages:

[0018] 1. This waste material cutting equipment for environmentally friendly building material preparation achieves uniform dust suppression by setting up a knife holder, dust suppression nozzles, a pre-wetting rack, and a cleaning rack. When the material is continuously conveyed through the pre-wetting rack, it is sprayed from multiple directions by the diffusion nozzles, so that the surface of the material is initially pre-wetted. Then, when the material is below the cylinder, the cylinder is activated, and the knife holder and blades cut the material. Because the material is pre-wetted by the spray of the pre-wetting rack before being cut, less dust overflows during cutting. During cutting, the dust suppression nozzles spray water, which cools the blades and suppresses dust during cutting, so that the dust is wetted as soon as it appears, preventing it from flying in the air. Then, the output roller belt continues to convey the material. When the material passes the cleaning rack, the side nozzles wash the surface of the material from two directions, washing away the remaining adhering dust and debris, thus achieving a uniform dust suppression effect.

[0019] 2. This waste cutting equipment for the preparation of environmentally friendly building materials achieves dust reuse through the setting of a water storage chamber, a water collection tank, and a variable frequency pump. Water sprayed from the pre-wetting frame, dust suppression nozzles, and side nozzles follows the dust and debris through the water collection tank and falls onto the top of the filter plate. The filter plate performs dual filtration of water and impurities. First, the coarse-pore sponge blocks large particles of dust and debris on its surface. After small particles of dust and water are filtered by the fine-pore sponge, the water flows through the fine-pore sponge into the water storage chamber, achieving the effect of filtering dust and debris and reusing water.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-3 A waste material cutting device for the preparation of environmentally friendly building materials includes a box body 1. The box body 1 has an inlet and an outlet on both sides. Dust baffles 11 are rotatably installed at both the inlet and outlet of the box body 1. Conveying devices 2 are installed inside the box body 1 at both the inlet and outlet. A water storage chamber 12 is opened inside the box body 1. A water collection tank 13 is opened between the inside of the box body 1 and the water storage chamber 12. A filter plate 3 is movably installed inside the box body 1 between the water storage chamber 12 and the water collection tank 13. A variable frequency pump 4 is installed on one side of the box body 1. A cylinder 5 is fixedly installed on the top of the box body 1. A pre-wetting rack 6 and a cleaning rack 7 are installed on both sides of the cylinder 5 inside the box body 1.

[0027] In practical applications, this device achieves a certain dust reduction effect through the cooperation between the dust baffle 11, the dust suppression nozzle 52, the pre-wetting frame 6, and the washing frame 7. When the material enters the housing 1 through the feed roller belt 21, it first pushes the dust baffle 11 into the housing 1. Then, the dust baffle 11 naturally falls back to its original position due to gravity. When the material passes through the pre-wetting frame 6, it is sprayed in multiple directions by the diffusion nozzle 61, so that the surface of the material is initially pre-wetted. Then, when the material is below the cylinder 5, the cylinder 5 is activated, and the knife holder 51 and the blade cut the material. During the cutting, the dust suppression nozzle 52 sprays water. This process serves to reduce dust and cool the material during cutting, ensuring that dust is moistened by water as soon as it appears, preventing it from flying in the air. Subsequently, the output roller belt 22 conveys the material. When the material is positioned at the cleaning frame 7, the side nozzles 71 rinse the material surface from two directions, washing away any remaining adhering dust and debris. The water sprayed from the pre-wetting frame 6, dust-reducing nozzles 52, and side nozzles 71 follows the dust and debris through the water collection tank 13 and falls above the filter plate 3. After double filtration by the filter plate 3, the dust and debris remain on the surface of the filter plate 3, while the water is filtered into the water storage chamber 12, achieving a reflux effect.

[0028] Please see Figures 1-3 The conveying device 2 includes an infeed roller belt 21 and an output roller belt 22. The infeed roller belt 21 is rotatably installed inside the housing 1 between the inlet and the outlet. The output roller belt 22 is rotatably installed inside the housing 1 between the outlet and the outlet. There is a certain gap between the infeed roller belt 21 and the output roller belt 22.

[0029] The conveying device 2 is an existing structure inside the existing device, so it is not explained or set in detail in this application. It is only regarded as a conventional application of the prior art. The input roller belt 21 conveys the material until it is conveyed between the input roller belt 21 and the output roller belt 22. Then, the cylinder 5 processes and cuts it, and then it is conveyed out of the box 1 through the output roller belt 22.

[0030] Please see Figures 1-4 The filter plate 3 has two layers of placement slots inside, located at the connection between the water storage chamber 12 and the water collection tank 13. The upper placement slot is fixedly installed with a coarse-pore sponge 31, and the lower placement slot is fixedly installed with a fine-pore sponge 32. The pore size of the fine-pore sponge 32 is smaller than that of the coarse-pore sponge 31, so that the coarse-pore sponge 31 can filter out large dust particles, and the fine-pore sponge 32 can filter out small dust particles. Water can flow back into the water storage chamber 12 through the coarse-pore sponge 31 and the fine-pore sponge 32.

[0031] Cylinder 5, pre-wetting rack 6, and cleaning rack 7 all spray water onto the material, achieving the effects of dust reduction and debris removal. The water mixed with dust and debris is collected by the water collection tank 13 and filtered by the water filter plate 3. The water filter plate 3 performs dual filtration of water and impurities. First, the coarse-pore sponge 31 blocks large particles of dust and debris on its surface. After the small particles of dust and water are filtered by the fine-pore sponge 32, the water flows through the fine-pore sponge 32 into the water storage chamber 12, realizing the utilization of water resources. Since the requirements for water purity are not high in the cutting and machining processes, the cooling and dust reduction water of this application can be reused.

[0032] Please see Figures 1-3 The variable frequency pump 4 is connected to the water storage chamber 12. The variable frequency pump 4 is located inside the housing 1 and connected to the pump outlet pipe 41. The pump outlet pipe 41 is located inside the inner wall of the housing 1 and connected to the dispersion pipe 42.

[0033] When the variable frequency pump 4 is started, the variable frequency pump 4 pumps the water inside the water storage chamber 12 out through the pump outlet pipe 41, and finally distributes it through the dispersion pipe 42. The dispersion pipe 42 evenly distributes the water into the dust suppression nozzle 52, the diffusion nozzle 61 and the side nozzle 71, so as to achieve the effect of multiple water supply.

[0034] Please see Figures 1-3 Below the output shaft of cylinder 5, inside the housing 1, a tool holder 51 is fixedly connected. The bottom of the tool holder 51 is provided with a blade. The tool holder 51 is located between the input roller belt 21 and the output roller belt 22. Water pipes and dust suppression nozzles 52 are installed on both sides of the middle part of the tool holder 51. The water pipes are connected to the dispersion pipe 42 and the dust suppression nozzles 52. The dust suppression nozzles 52 are fan-shaped nozzles. The spray direction of the dust suppression nozzles 52 is located at the end of the blade of the tool holder 51.

[0035] The cylinder 5 controls the descent of the cutter holder 51 by driving its output shaft, and then cuts the material. During the cutting process, the variable frequency pump 4 supplies water to the dust suppression nozzle 52, so that the water sprayed by the dust suppression nozzle 52 can cool down in time when the cutter holder 51 is cutting, and the dust generated by cutting is also wetted by water to prevent dust from flying and leaking.

[0036] Please see Figures 1-3 The pre-wetting frame 6 is installed on the feed port side of the box 1 and is located on the outer ring of the feed roller belt 21. The inner surface of the pre-wetting frame 6 is uniformly provided with spray holes in a linear array. A diffusion nozzle 61 is fixedly installed inside the spray hole. The diffusion nozzle 61 is embedded and is connected to the end of the dispersion tube 42.

[0037] The pre-wetting frame 6 is continuously supplied with water through the dispersion pipe 42, so that water is evenly sprayed out through the diffusion nozzle 61 during operation. When the material is conveyed by the feed roller belt 21, the diffusion nozzle 61 evenly wets the surface of the material, so that dust is generated as little as possible during processing, thus achieving the effect of dust reduction.

[0038] Please see Figures 1-3 The cleaning frame 7 is installed on the discharge port side of the housing 1 and is located on the outer ring of the output roller belt 22. A side nozzle 71 is symmetrically installed on the bottom surface of the cleaning frame 7. The spraying direction of the side nozzle 71 is located on the surface of the output roller belt 22. The side nozzle 71 is connected to the other end of the dispersion tube 42.

[0039] In actual operation, the cleaning rack 7 is located in the final process. When the cylinder 5 moves to the position of the cleaning rack 7 after cutting the material, the cleaning rack 7 will continuously spray water due to the water supply from the dispersion pipe 42. The material and surface are washed by the two lateral water flows, so that dust particles and debris are flushed to both sides, so that the surface of the cut material is no longer adsorbed with dust and debris.

[0040] Working Principle: During operation, when the material enters the housing 1 via the feed roller belt 21, it first pushes the dust baffle 11 inwards. Then, the dust baffle 11 naturally returns to its original position due to gravity. Next, the variable frequency pump 4 is activated, pumping water from the water storage chamber 12 out through the pump outlet pipe 41. The water is then distributed through the dispersion pipe 42 to the diffusion nozzles 61, dust suppression nozzles 52, and side nozzles 71 for spraying. As the material continues to be conveyed through the pre-wetting frame 6, it is pre-wetted by the multi-directional spray from the diffusion nozzles 61. When the material is below the cylinder 5, the cylinder 5 is activated, and the blade holder 51 and blades cut the material. Because the material is pre-wetted by the spray from the pre-wetting frame 6 before cutting, less dust overflows during cutting. During the cutting process, the dust-suppressing nozzle 52 sprays water to cool the blade and suppress dust during cutting. This wets the dust as soon as it appears, preventing it from flying in the air. Subsequently, the output roller belt 22 continues to transport the material. When the material passes the cleaning frame 7, the side nozzles 71 wash the surface of the material from two directions, washing away any remaining adhering dust and debris. The water sprayed from the pre-wetting frame 6, the dust-suppressing nozzle 52, and the side nozzles 71 follows the dust and debris through the water collection tank 13 and falls onto the water filter plate 3. The water filter plate 3 performs dual filtration of water and impurities. First, the coarse-pore sponge 31 blocks large particles of dust and debris on its surface. After the small particles of dust and water are filtered by the fine-pore sponge 32, the water flows through the fine-pore sponge 32 into the water storage chamber 12, realizing the reuse of water resources.
