Description

Technical Field

[0001] This application relates to the field of biomass energy technology, and more specifically, to a crusher and processing equipment. Background Technology

[0002] Biomass fuel refers to fuel made by burning biomass materials, primarily agricultural and forestry waste, as opposed to fossil fuels. Direct combustion of biomass is considered a highly polluting fuel and is only permitted for use in rural stoves, not in cities. The actual application of biomass fuel mainly involves biomass briquettes, which are made from agricultural and forestry waste through processes such as crushing, mixing, extrusion, and drying to create various shapes (e.g., blocks, pellets) that can be directly burned—a new type of clean fuel.

[0003] Currently, biomass raw material crushers tend to generate a lot of dust when operating at high speeds, so dust removal is particularly important. Utility Model Content

[0004] The purpose of this application is to provide a crusher and processing equipment that can achieve dust removal.

[0005] In a first aspect, embodiments of this application provide a crusher, comprising: a crushing structure, including a crushing mechanism and a conveying mechanism, wherein the crushing mechanism is used to crush materials, and the conveying mechanism is disposed on one side of the crushing mechanism for conveying the materials to the crushing mechanism and / or for conveying the materials crushed by the crushing mechanism; and a dust removal structure, including a dust removal duct and a first pipe, wherein the dust removal duct is disposed above the crushing structure and is distributed along the material movement direction, and the first pipe is connected to the dust removal duct.

[0006] In the above process, the crushing mechanism is located on one side of the transport mechanism. The transport mechanism can transport materials to the crushing mechanism, which then crushes the materials to achieve the crushing effect. The dust removal duct is connected to the first pipe and is located above the crushing structure. When the transport mechanism transports the material to the crushing mechanism for crushing, the dust removal duct and the first pipe can form a negative pressure during the entire material transport process and / or the crushing process of the crushing mechanism, so as to discharge dust from the inside of the crusher and achieve the dust removal effect.

[0007] In some embodiments, the dust removal structure further includes a dust removal frame, the upper end of which is provided with the dust removal duct, and at least two dust removal ducts are distributed at intervals along the material movement direction; The first duct is located on the outside of the dust removal frame and is connected to the two dust removal air ducts respectively.

[0008] In the above implementation process, the dust removal frame is equipped with at least two dust removal air ducts, and the two dust removal air ducts are distributed at intervals. After being connected to the first duct, the rate at which negative pressure is generated in the dust removal frame can be increased, thereby improving the dust removal effect and facilitating the centralized treatment of dust.

[0009] In some embodiments, the dust removal duct extends from the material feeding location to the location of the crushing mechanism.

[0010] In the above implementation process, by setting the length of the dust removal duct to be long enough to distribute along the path where dust is generated, most of the dust generated during the movement and crushing process can be collected in a concentrated manner, preventing dust from overflowing and improving the working environment.

[0011] In some embodiments, the dust removal frame has a dust removal chamber, and the dust removal frame is provided with a feed inlet, which communicates with the dust removal chamber.

[0012] In the above implementation process, the dust removal chamber has no other exposed structures except for the feed inlet, which is conducive to forming a closed integration, which can more effectively collect dust, prevent dust from overflowing, and improve the working environment. The feed inlet can be used by users to put materials into the transportation mechanism, thereby facilitating the crushing mechanism to crush the materials.

[0013] In some embodiments, the dust removal structure further includes a dust removal curtain connected to the dust removal frame and located at the feed inlet.

[0014] In the above process, the dust removal curtain is set at the feed inlet, which can block the only opening of the dust removal chamber. This not only helps the dust removal chamber to quickly form negative pressure and further prevents dust from overflowing, but also facilitates the feeding of materials.

[0015] In some embodiments, the dust removal structure further includes a second pipe, one end of which is disposed above the crushing mechanism, and the other end extends to the outside of the dust removal frame and communicates with the first pipe.

[0016] In the above process, the second pipe is located above the crushing mechanism and is connected to the first pipe. Through the cooperation of the second pipe and the dust removal duct, dust removal can be achieved at different locations of the crushing structure, which can improve the dust removal effect, prevent dust from overflowing, and improve the working environment.

[0017] In some embodiments, the crushing mechanism includes a feeding roller and a crushing rotor. The feeding roller is located on one side of the crushing rotor. The feeding roller is used to press and feed the material, and the crushing rotor is used to crush the material pressed by the feeding roller.

[0018] In the above process, the feeding roller is located on one side of the crushing rotor. When the material moves to a position close to the crushing rotor, the feeding roller presses the material, which facilitates the material to move to the crushing rotor. This is beneficial for the crushing rotor to crush the material, improves the crushing effect, and thus improves the working efficiency.

[0019] In some embodiments, the crushing mechanism further includes a tilting frame located above the crushing rotor and connected to the second pipe.

[0020] In the above process, the tilting frame is set above the crushing rotor, which not only facilitates the entry of materials into the crushing rotor and is beneficial to the crushing of materials by the crushing rotor, but also allows the second pipe on the tilting frame to collect the dust generated by the crushing rotor during crushing, thereby improving the crushing effect.

[0021] In some embodiments, the transport mechanism includes a feeding component and a discharging component. The feeding component is disposed on one side of the crushing mechanism for feeding material to the crushing mechanism, and the discharging component is disposed below the crushing mechanism for conveying the crushed material.

[0022] In the above process, the feeding component is used to transport the material to the crushing mechanism, and the discharge component is used to transport the material after it has been crushed by the crushing mechanism. This facilitates the transmission and collection of materials, realizes the reuse of energy, and the whole process is fully automated crushing, which improves crushing efficiency.

[0023] Secondly, this application also provides a processing apparatus, including a crusher as described in any of the preceding claims.

[0024] In the above process, the crushing mechanism is located on one side of the transport mechanism. The transport mechanism can transport materials to the crushing mechanism, where the crushing mechanism crushes the materials to achieve the crushing effect. The dust removal duct is connected to the first pipe and is located above the crushing structure. When the transport mechanism transports materials to the crushing mechanism for crushing, the dust removal duct and the first pipe can form a negative pressure during the entire material transport process and / or the crushing process, expelling dust from the inside of the crusher to achieve the dust removal effect. The entire process can realize the automatic processing and transport of materials, improving work efficiency.

[0025] Other features and advantages of this application will be set forth in the following description, or some features and advantages may be inferred from the description or determined without doubt, or may be learned by practicing the above-described techniques of this application.

[0036] Biomass energy crushers can crush and process waste materials from forestry and animal husbandry, such as miscellaneous wood, straw, and other biomass raw materials, making them suitable for combustion in biomass power plant furnaces. This fuel is an ideal alternative to oil and coal, solving the energy utilization problem of forestry and animal husbandry waste and straw. However, during the crushing process, the high-speed rotation of the rotor easily generates a large amount of dust. Traditional biomass energy crushers lack dedicated dust removal structures; they often consist of a large welded protective cover, which is bulky, inconvenient to transport, and has poor dust removal efficiency.

[0037] In view of this, such as Figures 1-3As shown, in a first aspect, this application provides a crusher for crushing biomass raw materials. The crusher includes a crushing structure 1 and a dust removal structure 2. The dust removal structure 2 is disposed above the crushing structure 1. With the cooperation of the dust removal structure 2 and the crushing structure 1, a relatively closed environment can be formed. The crushing structure 1 is used for crushing materials, and the dust removal structure 2 is used for collecting and treating the generated dust.

[0038] Specifically, the crushing structure 1 includes a crushing mechanism and a conveying mechanism. The crushing mechanism is used to crush materials, and the conveying mechanism is located on one side of the crushing mechanism to transport the materials to the crushing mechanism and / or to transport the materials crushed by the crushing mechanism. The dust removal structure 2 includes a dust removal duct 201 and a first pipe 202. The dust removal duct 201 is located above the crushing structure 1 and is distributed along the material movement direction. The first pipe 202 is connected to the dust removal duct 201.

[0039] For example, the crushing mechanism refers to the component used to crush materials, and the transport mechanism refers to the component used to transport materials. Through the cooperation of the transport mechanism and the crushing mechanism, the transportation and crushing of materials can be realized. After the crushed materials are processed, they are easy to burn in the biomass power plant's combustion furnace. This fuel is an ideal fuel that can replace oil and coal, and can solve the energy recycling of pasture and forestry waste and straw.

[0040] The dust removal structure 2 refers to the component used for dust collection. The dust removal structure 2 is set above the crushing structure 1 and can collect the dust generated by the crushing structure 1 during operation. The dust removal structure 2 and the crushing structure 1 can be connected in a detachable manner to facilitate subsequent docking, and / or the dust removal structure 2 is an assembled structure that can be disassembled into parts, with a small size and convenient transportation.

[0041] The first duct 202 of the dust removal structure 2 includes a main duct and a duct. The duct is connected to the dust removal duct 201 and the main duct. One end of the main duct is used to connect to dust removal equipment such as a cyclone or pulse dust collector. The dust removal fan is used to suck away the collected dust to achieve centralized dust treatment.

[0042] In the above process, the crushing mechanism is located on one side of the transport mechanism. The transport mechanism can transport materials to the crushing mechanism, which then crushes the materials to achieve the crushing effect. The dust removal duct 201 is connected to the first pipe 202. The dust removal duct 201 is located above the crushing structure 1. When the transport mechanism transports the material to the crushing mechanism for crushing, the entire process of transporting the material and / or the crushing process of the crushing mechanism can form a negative pressure in the dust removal duct 201 and the first pipe 202, which will discharge the dust from the inside of the crusher and achieve the effect of dust removal.

[0043] like Figures 1-3 As shown, the dust removal structure 2 also includes a dust removal frame, and the upper end of the dust removal frame is provided with the dust removal air duct 201. At least two dust removal air ducts 201 are distributed at intervals along the material movement direction. The first pipe 202 is located on the outside of the dust removal frame and is connected to the two dust removal air ducts 201 respectively.

[0044] For example, the dust removal frame includes a frame body 203, an upper cover 204, a sealing plate 205, and a crash plate 206. The frame body 203 is distributed in the left and right direction. The upper cover 204 is connected to the upper end of the frame body 203, and the front and / or rear sides of the upper cover 204 are set in the dust removal duct 201. The sealing plate 205 is connected to the left and right ends of the frame body 203. The crash plate 206 is set at the rear end of the frame body 203. The crash plate 206 can prevent the loader and materials from causing significant damage to the dust removal structure 2 during the feeding process. The front end of the frame body 203 is used for material feeding. The structure of the entire dust removal frame can be set as an assembled structure, that is, the frame body 203, the upper cover 204, the sealing plate 205, and the crash plate 206 can be disassembled into independent parts, which are small in size and convenient for transportation.

[0045] In the above implementation process, the dust removal frame is provided with at least two dust removal air ducts 201, and the two dust removal air ducts 201 are distributed at intervals. After being connected to the first pipe 202, the rate of negative pressure generation in the dust removal frame can be increased, the dust removal effect can be improved, and the dust can be centrally processed.

[0046] like Figure 2 As shown, the dust removal duct 201 extends from the material feeding position to the crushing mechanism. For example, the frame body 203 is distributed along the left-right direction, and the dust removal duct 201 extends from the left end to the right end of the frame body 203, thereby collecting dust generated throughout the entire process from feeding to discharging. It should be noted that the dust removal duct 201 includes several duct plates connected to enclose a dust removal space for collecting dust.

[0047] In the above implementation process, by setting the length of the dust removal duct 201 to be long enough to be distributed along the path where dust is generated, most of the dust generated during the movement process and crushing can be collected in a concentrated manner, preventing dust from overflowing and improving the working environment.

[0048] like Figures 1-2 As shown, the dust removal frame has a dust removal chamber and a feed inlet 207. The feed inlet 207 is connected to the dust removal chamber and is located at the front end of the dust removal frame. The dust removal chamber is connected to the aforementioned dust removal space.

[0049] In the above implementation process, the dust removal chamber has no other exposed structures except for the feed inlet 207, which is conducive to forming a closed integration, which can more effectively collect dust, prevent dust from overflowing, and improve the working environment. The feed inlet 207 can be used as a part for users to put materials into the transport mechanism, thereby facilitating the crushing mechanism to crush the materials.

[0050] In some embodiments, the dust removal structure 2 further includes a dust removal curtain 209, which is connected to the dust removal frame. The connection method includes snap-fit, sliding connection, screw connection, etc. The dust removal curtain 209 is located at the feed inlet 207. Several dust removal curtains 209 are provided, and the several dust removal curtains 209 are distributed in the left and right direction. Adjacent dust removal curtains 209 are in sealed contact.

[0051] In the above process, the dust removal curtain 209 is set at the feed inlet 207, which can block the only opening of the dust removal chamber. This not only helps the dust removal chamber to quickly form a negative pressure and further prevents dust from overflowing, but also facilitates the feeding of materials.

[0052] like Figures 1-2 As shown, the dust removal structure 2 also includes a second pipe 208, one end of which is located above the crushing mechanism, and the other end extends to the outside of the dust removal frame and is connected to the first pipe 202.

[0053] In the above process, the second pipe 208 is located above the crushing mechanism and is connected to the first pipe 202. Through the cooperation of the second pipe 208 and the dust removal duct 201, dust removal can be achieved at different positions of the crushing structure 1, which can improve the dust removal effect, prevent dust from overflowing, and improve the working environment.

[0054] like Figure 1 As shown, the crushing mechanism includes a feeding roller 101 and a crushing rotor 102. The feeding roller 101 is located on one side of the crushing rotor 102. The feeding roller 101 is used to press and feed the material, and the crushing rotor 102 is used to crush the material pressed by the feeding roller 101.

[0055] For example, the feeding roller 101 is a component used to press and convey materials, and the crushing rotor 102 is a component used to crush materials, wherein the feeding roller 101 can be driven by a first driving member, and the crushing rotor 102 can be driven by a second driving member.

[0056] The crushing mechanism also includes a screen, which is located around the periphery of the crushing rotor 102. At least part of the screen structure is located below the crushing rotor 102. After the material passes through the feeding roller 101, it enters the crushing chamber 106. The crushing rotor 102 in the crushing chamber 106 rotates at high speed to crush the material. The crushed material passes through the screen and falls into the discharge component 105 below.

[0057] In the above process, the feeding roller 101 is located on one side of the crushing rotor 102. When the material moves to a position close to the crushing rotor 102, the feeding roller 101 presses the material, which facilitates the material to move to the crushing rotor 102, prevents the material from rolling, and is conducive to the crushing of the material by the crushing rotor 102, thereby improving the crushing effect and improving the working efficiency.

[0058] like Figure 1 As shown, the crushing mechanism also includes a tilting frame 103, which is located above the crushing rotor 102. The feeding roller 101 is located on the feeding port side of the tilting frame 103, and the tilting frame 103 is connected to the second pipe 208. The tilting frame 103 is the mounting frame for the feeding roller 101 and can be raised and lowered to control the feeding thickness for pressing.

[0059] In the above process, the tilting frame 103 is set above the crushing rotor 102, which not only facilitates the entry of materials into the crushing rotor 102 and is beneficial to the crushing of materials by the crushing rotor 102, but also provides a second pipe 208 on the tilting frame 103 to collect the dust generated by the crushing rotor 102 during crushing, thereby improving the crushing effect.

[0060] In some embodiments, the transport mechanism includes a feeding component 104 and a discharging component 105. The feeding component 104 is disposed on one side of the crushing mechanism for feeding material to the crushing mechanism, and the discharging component 105 is disposed below the crushing mechanism for conveying the crushed material.

[0061] For example, both the feeding assembly 104 and the discharging assembly 105 can adopt existing structures. The feeding assembly 104 includes a first conveyor belt, a feeding roller, and a feeding drive. The first conveyor belt is sleeved on the feeding roller, and the feeding drive is connected to the feeding roller. The discharging assembly 105 includes a second conveyor belt, a discharging roller, and a discharging drive. The second conveyor belt is sleeved on the discharging roller, and the discharging drive is connected to the discharging roller.

[0062] In the above process, the feeding component 104 is used to transport the material to the crushing mechanism, and the discharge component 105 is used to transport the material after it has been crushed by the crushing mechanism. This facilitates the transmission and collection of the material and enables the reuse of energy. The whole process is fully automated crushing, which improves the crushing efficiency.

[0063] Secondly, this application also provides a processing apparatus, including the crusher described above.

[0064] For example, the processing equipment also includes a dust removal structure 2 and a loader. The loader is used to transport materials. The dust removal structure 2 is connected to the first pipe 202 of the crusher. The dust removal fan of the dust removal structure 2 is used to suck away the collected dust and centrally process the dust.

[0065] In the above process, the crushing mechanism is located on one side of the transport mechanism. The transport mechanism can transport materials to the crushing mechanism, where the crushing mechanism crushes the materials to achieve the crushing effect. The dust removal duct 201 is connected to the first pipe 202 and is located above the crushing structure 1. When the transport mechanism transports materials to the crushing mechanism for crushing, the dust removal duct 201 and the first pipe 202 can form a negative pressure during the entire material transport process and / or the crushing process of the crushing mechanism, thereby discharging dust from the inside of the crusher and achieving the dust removal effect. The entire process can realize the automatic processing and transport of materials, improving work efficiency.
