Description

Technical Field

[0001] This utility model relates to the field of pneumatic pulverizer technology, specifically a pneumatic pulverizer. Background Technology

[0002] In the process of producing anhydrous ethanol from biomass fermentation, the crushing of biomass raw materials (such as straw, corn cobs, sugarcane bagasse, etc.) is a key pretreatment step. It is required that the crushed material has a uniform particle size (usually 0.1-1mm) and a fully broken fiber structure in order to improve the efficiency of subsequent enzymatic hydrolysis and ethanol conversion rate.

[0003] In existing technology, a servo motor is used to drive the impact block inside the crushing device to rotate, thereby crushing the raw materials in the crushing box and making the crushed material particles uniform.

[0004] However, in actual use, when the pneumatic pulverizer is pulverizing materials, it will carry the materials into the pulverizing device. Because the material particles are large, they are easy to block the outlet of the feeding device when feeding, which will affect the feeding effect and reduce the working efficiency of the pulverizing device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a pneumatic pulverizer that solves the problem that, during actual use, when the pneumatic pulverizer is pulverizing materials, the materials are carried into the pulverizing device. Due to the large size of the material particles, they are easily blocked at the outlet of the feeding device during feeding, thus affecting the feeding effect and reducing the working efficiency of the pulverizing device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic pulverizer includes a mounting plate, a pulverizing chamber fixedly connected to the top of the mounting plate, a connecting pipe connected to one side of the pulverizing chamber, a high-pressure pump connected to the end of the connecting pipe, impact blocks installed inside the pulverizing chamber, and the bottom of the high-pressure pump fixedly connected to the top of the mounting plate. The pneumatic pulverizer also includes a feeding device installed on the top of the connecting pipe; a quick-release structure installed on the outer wall of the pulverizing chamber; and a connecting assembly installed on the inner wall of the pulverizing chamber. The feeding device ensures stable material feeding, the quick-release structure allows for rapid disassembly of the pulverizing chamber, and the connecting assembly connects the impact blocks together.

[0007] Preferably, the feeding device includes a material box, which is fixedly connected to the top of the mounting plate and its bottom is connected to the top of the connecting pipe; a servo motor is fixedly connected to the top of the material box, and its output end passes through the material box through a sealed bearing; an auger is fixedly connected to the output end of the servo motor, and its outer wall is movably connected to the inner wall of the material box; wherein, through the cooperation of the material box and the auger, the material entering the connecting pipe from the material box will not be blocked.

[0008] Preferably, the feeding device further includes a one-way valve, which is installed between the material box and the connecting pipe.

[0009] Preferably, the quick-release structure includes a limiting ring, which is fixedly connected to the upper part of the outer wall of the crushing box; a fixing ring is fixedly connected to the lower part of the outer wall of the crushing box; a threaded rod is rotatably connected to the inner wall of the fixing ring via a pin and inserted into the inner wall of the limiting ring; a limiting block is threadedly connected to the outer wall of the threaded rod, and its bottom abuts against the top of the limiting ring; wherein, the limiting ring and the fixing ring are connected together through the cooperation of the threaded rod and the limiting block.

[0010] Preferably, the connecting assembly includes a fixing block abutting against the outer wall of the impact block; a pin is fixedly connected to the outer wall of the fixing block and inserted into the inner wall of the impact block; wherein the impact blocks are connected together through the cooperation of the fixing block and the pin. Beneficial effects

[0011] This utility model provides a pneumatic pulverizer. It has the following advantages: Through the cooperation of a feeding device, a hopper, and a servo motor, the servo motor drives an auger to rotate within the hopper. The auger propels the material within the hopper, ensuring stable material flow into the pulverizing chamber through the connecting pipe. This solves the problem that larger material particles easily clog the outlet of the feeding device during feeding, thus affecting the feeding effect and reducing the pulverizing device's efficiency.

[0012] By using the combination of the limiting ring, the fixing ring, and the threaded rod, when the impact block inside the crushing box is being repaired or replaced, the fixing ring and the limiting ring are connected together through the cooperation of the threaded rod and the limiting block. This makes it convenient to disassemble the crushing box and solves the problem that workers need to remove the fixing bolts on the outer wall of the crushing box one by one and install them one by one during installation, which would increase the working time of the workers.

[0015] 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.

[0016] In actual use, when the pneumatic pulverizer is pulverizing materials, it will carry the materials into the pulverizing device. Because the material particles are large, they are easy to block the outlet of the feeding device when feeding, which will affect the feeding effect and reduce the working efficiency of the pulverizing device.

[0017] In view of this, the present invention provides a pneumatic pulverizer, which solves the problem that when the pneumatic pulverizer is pulverizing materials, the materials are carried into the pulverizing device. Due to the large size of the material particles, they are easily blocked at the outlet of the feeding device during feeding, which affects the feeding effect and reduces the working efficiency of the pulverizing device.

[0018] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0019] Example 1: By Figure 1-5 It is known that a pneumatic pulverizer includes a mounting plate 1, a pulverizing chamber 2 fixedly connected to the top of the mounting plate 1, a connecting pipe 8 connected to one side of the pulverizing chamber 2, a high-pressure pump 4 connected to the end of the connecting pipe 8, an impact block 3 installed inside the pulverizing chamber 2, and the bottom of the high-pressure pump 4 fixedly connected to the top of the mounting plate 1. The pneumatic pulverizer also includes a feeding device 5, a quick-release structure 6, and a connecting assembly 7. The feeding device 5 is installed on the top of the connecting pipe 8; the quick-release structure 6 is installed on the outer wall of the pulverizing chamber 2; and the connecting assembly 7 is installed on the inner wall of the pulverizing chamber 2. The feeding device 5 ensures stable material feeding, the quick-release structure 6 quickly disassembles the pulverizing chamber 2, and the connecting assembly 7 connects the impact blocks 3 together. In the specific implementation process, it is worth noting that the model of the high-pressure pump 4 is not limited, as long as it meets the actual use conditions. By compressing the air, the material is made to quickly impact the inner wall of the crushing box 2, thereby crushing the material. The impact blocks 3 set in the crushing box 2 can make the material crush more thoroughly. The crushing box 2 is divided into upper and lower parts, which are connected together by the quick-release structure 6. The feeding device 5 can ensure that the material enters the crushing box 2 stably through the connecting pipe 8. The connecting component 7 can connect the impact blocks 3 together. By changing the size of the impact blocks 3, the degree of material crushing can be changed. Moreover, the top of the crushing box 2 can be connected to the processing device through a flange, which is convenient for subsequent processing after the material is crushed. Furthermore, the feeding device 5 includes a material box 51, a servo motor 52, and an auger 53. The material box 51 is fixedly connected to the top of the mounting plate 1, and its bottom is connected to the top of the connecting pipe 8. The servo motor 52 is fixedly connected to the top of the material box 51, and its output end passes through the material box 51 through a sealed bearing. The auger 53 is fixedly connected to the output end of the servo motor 52, and its outer wall is movably connected to the inner wall of the material box 51. Through the cooperation of the material box 51 and the auger 53, the material entering the connecting pipe 8 from the material box 51 will not be blocked. In the specific implementation process, it is worth noting that the bottom of the material box 51 is conical to facilitate the discharge of materials in the material box 51, and the outer wall of the auger 53 is movably connected to the discharge port at the bottom of the material box 51. The top of the material box 51 is equipped with a box cover to ensure convenience when adding materials. When adding materials into the crushing box 2, the servo motor 52 drives the auger 53 to rotate. Through the pushing and stirring of the auger 53, the materials are stabilized when entering the connecting pipe 8. When the materials enter the connecting pipe 8, the high-pressure pump 4 will cause the materials in the connecting pipe 8 to enter the crushing box 2. When the gas is continuously blown into the crushing box 2, the materials in the crushing box 2 will rotate around the inner wall of the crushing box 2 and impact, thereby crushing the materials. After the materials are crushed, their volume is reduced, and under the drive of the gas, they are discharged through the opening at the top of the crushing box 2 and enter the subsequent processing device. Furthermore, the feeding device 5 also includes a one-way valve 54, which is installed between the material box 51 and the connecting pipe 8; In the specific implementation process, it is worth noting that the one-way valve 54 will ensure that when the material is discharged, the gas in the connecting pipe 8 will not enter the material box 51 through the connection between the material box 51 and the connecting pipe 8, thereby avoiding gas leakage that may affect the crushing of the material. The model of the one-way valve 54 is not limited, as long as it meets the actual use conditions.

[0020] Example 2: From Figure 1-5As can be seen, the quick-release structure 6 includes a limiting ring 61, a fixing ring 62, a threaded rod 63, and a limiting block 64. The limiting ring 61 is fixedly connected to the upper part of the outer wall of the crushing box 2; the fixing ring 62 is fixedly connected to the lower part of the outer wall of the crushing box 2; the threaded rod 63 is rotatably connected to the inner wall of the fixing ring 62 via a pin and is inserted into the inner wall of the limiting ring 61; the limiting block 64 is threadedly connected to the outer wall of the threaded rod 63, and its bottom abuts against the top of the limiting ring 61; wherein, through the cooperation of the threaded rod 63 and the limiting block 64, the limiting ring 61 and the fixing ring 62 are connected together. In the specific implementation process, it is worth noting that the crushing box 2 is divided into an upper part and a lower part. A protective shell is set at the bottom of the lower crushing box 2. After the two are assembled together, the protective shell at the bottom of the lower crushing box 2 will be inserted into the top of the inner wall of the upper crushing box 2 to separate the crushing chamber and stabilize the material during crushing. A groove is opened at the top of the limiting ring 61. When assembling the upper and lower crushing boxes 2 together, the threaded rod 63 is rotated 90 degrees and inserted into the inner wall of the limiting ring 61, so that the limiting block 64 is inserted into the groove at the top of the limiting ring 61. The limiting block 64 is rotated, and through the threaded connection between the limiting block 64 and the threaded rod 63, the limiting block 64 is pressed against the top of the limiting ring 61, so that the upper and lower crushing boxes 2 are fixed together. This makes it convenient to inspect the inside of the crushing box 2. Furthermore, the connecting component 7 includes a fixing block 71 and a pin 72. The fixing block 71 abuts against the outer wall of the impact block 3; the pin 72 is fixedly connected to the outer wall of the fixing block 71 and inserted into the inner wall of the impact block 3; wherein, the impact blocks 3 are connected together by the cooperation of the fixing block 71 and the pin 72. In the specific implementation process, it is worth noting that multiple impact blocks 3 are provided, and the outer wall of the impact block 3 is provided with upward threaded protrusions. When the material rotates in the crushing box 2 under the drive of gas, the material will be crushed quickly. With the cooperation of the threads on the outer wall of the impact block 3, the material will be blown upward by the gas and moved upward in the crushing box 2, so that the crushed material can be discharged and processed.
