Description

Technical Field

[0001] This utility model relates to the field of surfactant production equipment technology, and in particular to a raw material pulverizer for surfactant production. Background Technology

[0002] In the field of surfactant production, if the raw material particles are large, the reaction may only occur on the outer layer, and the internal raw materials cannot fully participate in the reaction, resulting in long reaction time and low yield. However, after being crushed, the raw material particles are finer, and the reaction can proceed more uniformly and quickly, which greatly shortens the production cycle and improves production efficiency. Therefore, in the field of surfactant production, it is necessary to use surfactant raw material crushers to crush the surfactant production raw materials.

[0003] In existing technologies, different surfactant products have different requirements for the particle size of raw materials. For example, some surfactants used in high-end cosmetics need to be pulverized to a very fine particle size to ensure that they can be evenly dispersed in the cosmetics and exert their best effects. On the other hand, some surfactants used in industrial cleaning agents have relatively relaxed requirements for the particle size of raw materials. However, the discharge screen plates of existing raw material pulverizers used for surfactant production are usually fixed, which means that the size of the screen holes cannot be flexibly adjusted according to actual production needs, reducing the practicality and versatility of the device. At the same time, it is not convenient to replace and clean the discharge screen plates separately, thus increasing maintenance costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a raw material pulverizer for surfactant production, which has the advantages of easy maintenance and cleaning and high versatility. It solves the problem that the discharge screen plate of existing raw material pulverizers for surfactant production is usually fixed, which makes it impossible to flexibly adjust the size of the screen hole according to actual production needs, reducing the practicality and versatility of the device. At the same time, it is not convenient to replace and clean the discharge screen plate separately, thus increasing maintenance costs.

[0005] This utility model provides the following technical solution: A raw material pulverizer for the production of surfactants, comprising a base and a pulverizer housing. A drive motor is fixedly connected to the rear surface of the pulverizer housing, and a sealing door is rotatably connected to the front surface of the pulverizer housing. A feeding hopper is fixedly connected to the surface of the sealing door. A discharge port is fixedly connected to the bottom surface of the pulverizer housing. A pulverizing assembly is provided inside the pulverizer housing. The pulverizing assembly includes a fixing ring, and sliders are uniformly fixedly connected to the surface of the fixing ring. Sliding grooves are uniformly formed on the inner wall surface of the pulverizer housing, and fixing teeth are uniformly fixedly connected to the inner wall surface of the fixing ring. A through groove is provided. The output shaft surface of the drive motor is fixedly connected to the cutter disc via a coupling. The inside of the fixed ring is evenly provided with discharge screen plates. A connecting component is provided between the discharge screen plates and the fixed ring. The fixed ring is annular and its size is adapted to the internal space of the crusher housing to ensure stable installation inside the crusher housing. Slider blocks are evenly distributed on the outer surface of the fixed ring, with a minimum of four. The shape of each slider matches the groove on the inner wall of the crusher housing. The sliders and the fixed ring are fixedly connected by welding or integral molding to ensure the connection is firm and to allow the fixed ring to slide smoothly in the groove through the sliders for positioning.

[0006] Preferably, the fixing ring is slidably connected to the inside of the groove by a slider, and the fixing teeth are all set on both sides of the groove. The fixing teeth are evenly fixed on the inner wall surface of the fixing ring. The shape of the fixing teeth is a sharp triangular or trapezoidal tooth with the tooth tip facing the direction of the cutter head. The fixing teeth are evenly fixed on the fixing ring by welding and cooperate with the cutter head to play the role of impact, friction and cutting during the raw material crushing process.

[0007] Preferably, the fixed ring, fixed teeth, and cutter disc form a crushing space. The discharge screen plate is used to screen the crushed raw materials for the production of surfactants. The discharge screen plate has an arc-shaped plate structure, and its arc matches the arc of the inner wall of the fixed ring, so that it can fit tightly inside the fixed ring. The number of discharge screen plates is at least four. The surface of the screen plate is evenly distributed with screen holes. The shape of the screen holes is circular or square, and their size is determined according to the required particle size of the surfactant raw materials. The raw materials that pass through the screen holes are finished products that meet the particle size requirements and are discharged from the discharge port.

[0008] Preferably, the connecting assembly includes connecting grooves evenly spaced on the surface of the fixing ring near the sealing door; locking grooves evenly spaced on the surface of the fixing ring; handles fixedly connected to the surface of the discharge screen plate near the sealing door; limiting grooves spaced on the top surface of the discharge screen plate; locking blocks provided inside the discharge screen plate; limiting plates fixedly connected to both sides of the locking blocks; compression springs fixedly connected to the bottom surface of the limiting plates; and installation grooves spaced inside the discharge screen plate. The number of connecting grooves is the same as the number of discharge screen plates. The shape of the connecting grooves is a groove matching the edge of the discharge screen plate, and it is an arc-shaped groove. Its depth and width are slightly greater than the thickness and width of the edge of the discharge screen plate, ensuring that the discharge screen plate can slide smoothly into and be stably installed in the connecting groove. The connecting grooves serve as guides, allowing the discharge screen plate to move along a predetermined direction during installation and disassembly, ensuring the accuracy of installation and the convenience of disassembly.

[0009] Preferably, the discharge screen plate is slidably connected inside the connecting groove, the upper half of the locking block is slidably engaged inside the locking groove, and the lower half of the locking block is slidably connected inside the limiting groove. The size of the locking groove is set according to the size of the locking block, with a depth slightly greater than the thickness of the upper half of the locking block and a width slightly greater than the width of the upper half of the locking block, so that the upper half of the locking block can be smoothly engaged in the locking groove to fix the discharge screen plate.

[0010] Preferably, the limiting groove and the mounting groove are interconnected, the limiting plate is slidably connected inside the mounting groove, and the other end of the compression spring is fixedly connected to the bottom inner wall surface of the mounting groove. The size of the limiting groove is set according to the size of the lower half of the locking block, the depth is slightly greater than the thickness of the lower half of the locking block, and the width is slightly greater than the width of the lower half of the locking block, so as to provide space for the movement of the locking block and limit its movement range to prevent the locking block from deviating during the movement.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. Through the design of the connecting components, a detachable connection is achieved between the discharge screen plate and the fixing ring. When it is necessary to replace the discharge screen plate to meet the requirements of different particle sizes, the operator only needs to pull the handle to easily remove the discharge screen plate for cleaning or replacement. When reinstalling, the discharge screen plate is aligned with the connecting groove and pushed in. The locking block is pushed into the locking groove by the compression spring. This allows the device to flexibly adapt to the crushing and discharge requirements of different particle sizes, improving the practicality and versatility of the device. At the same time, it also facilitates the individual replacement and cleaning of the discharge screen plate, thereby reducing maintenance costs.

[0013] 2. By using the crushing and connecting components together, when maintenance and cleaning of the equipment are required, the operator can open the sealing door and pull the fixing ring out of the slide groove. At this time, only the cutter disc remains inside the crusher housing, which can be easily and directly rinsed with cleaning fluid and water. The rinsed water is discharged through the discharge port, which greatly simplifies the cleaning process and facilitates cleaning of the equipment's interior after processing. There is no need for complicated disassembly of the equipment, thereby reducing equipment damage, effectively extending the service life of the equipment, and reducing maintenance costs.

[0020] 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.

[0021] Please see Figure 1 - Figure 5This utility model provides an embodiment of a raw material pulverizer for the production of surfactants, comprising a base 1 and a pulverizer housing 2. A drive motor 3 is fixedly connected to the rear surface of the pulverizer housing 2, and a sealing door 4 is rotatably connected to the front surface of the pulverizer housing 2. A feeding hopper 5 is fixedly connected to the surface of the sealing door 4, and a discharge port 6 is fixedly connected to the bottom surface of the pulverizer housing 2. A pulverizing assembly 7 is provided inside the pulverizer housing 2. The pulverizing assembly 7 includes a fixing ring 71, a slider 72 is uniformly fixedly connected to the surface of the fixing ring 71, grooves 73 are uniformly formed on the inner wall surface of the pulverizer housing 2, fixing teeth 74 are uniformly fixedly connected to the inner wall surface of the fixing ring 71, and through grooves 75 are uniformly formed on the surface of the fixing ring 71. A cutter disc 76 is fixedly connected to the output shaft surface of the drive motor 3 through a coupling. A discharge screen plate 77 is uniformly arranged inside the fixing ring 71, and the discharge screen plate 77 is connected to the fixing ring 71. Each component is equipped with a connecting assembly 8. The fixing ring 71 is slidably connected to the inside of the slide groove 73 via the slider 72. The fixing teeth 74 are all located on both sides of the through groove 75. The fixing ring 71, the fixing teeth 74, and the cutter disc 76 form a crushing space. The discharge screen plate 77 is used to screen the crushed raw materials for the production of activators. In the crushing assembly 7, the fixing ring 71 is slidably positioned in the slide groove 73 via the slider 72, so that the fixing teeth 74 are in a relatively fixed state. The cutter disc 76 rotates under the drive of the drive motor 3, so that the raw materials for the production of activators are ground between the cutter disc 76 and the fixing teeth 74 under the rotation of the cutter disc 76. The raw materials are impacted, rubbed, and cut to achieve crushing. The through groove 75 allows the crushed raw materials to contact the discharge screen plate 77. The discharge screen plate 77 is used to screen the crushed raw materials. Only particles that meet the particle size requirements can be discharged through the screen holes. Particles that do not meet the requirements continue to be circulated and crushed in the crushing space.

[0022] Please see Figure 1 - Figure 5The connecting assembly 8 includes connecting grooves 81 evenly distributed on the surface of the fixing ring 71 near the sealing door 4; locking grooves 82 evenly distributed on the surface of the fixing ring 71; handles 83 fixedly connected to the surface of the discharge screen plate 77 near the sealing door 4; limit grooves 84 distributed on the top surface of the discharge screen plate 77; locking blocks 85 disposed inside the discharge screen plate 77; limit plates 86 fixedly connected to both sides of the locking blocks 85; compression springs 87 fixedly connected to the bottom surface of the limit plates 86; mounting grooves 88 distributed inside the discharge screen plate 77; the discharge screen plate 77 slidably connected to the inside of the connecting grooves 81; the upper half of the locking block 85 slidably engages with the inside of the locking grooves 82; the lower half of the locking block 85 slidably connects to the inside of the limit grooves 84; the limit grooves 84 and the mounting grooves 88 communicate with each other; the limit plates 86 slidably connect to the inside of the mounting grooves 88; and the other end of the compression springs 87 is fixedly connected to the inside of the sealing door 4. The connecting component 8 is fixedly connected to the bottom inner wall surface of the mounting groove 88. It is used to realize the detachable connection between the discharge screen plate 77 and the fixing ring 71. The connecting groove 81 provides positioning and guidance for the installation of the discharge screen plate 77. The locking groove 82 cooperates with the locking block 85 to realize the stable connection of the discharge screen plate 77 on the fixing ring 71. The handle 83 facilitates the operator to pull the discharge screen plate 77 for installation and removal. The limiting groove 84 restricts the movement range of the locking block 85. Under the action of the compression spring 87, the locking block 85 realizes the engagement and disengagement with the locking groove 82, thereby completing the fixing and removal of the discharge screen plate 77. The limiting plate 86 limits the movement of the locking block 85 to prevent it from coming out of the mounting groove 88. The compression spring 87 provides elastic force for the locking block 85, enabling it to automatically reset and engage with the locking groove 82. The mounting groove 88 provides installation space for the locking block 85, the limiting plate 86, and the compression spring 87.

[0023] Working principle: During operation, the drive motor 3 starts, and the output shaft of the drive motor 3 drives the cutter disc 76 to rotate inside the fixed ring 71 through the coupling. The fixed ring 71 is positioned along the sliding groove 73 on the inner wall of the crusher housing 2 by the slider 72. The fixed teeth 74 on the inner wall of the fixed ring 71 and the rotating cutter disc 76 form a high-efficiency crushing space. The operator puts the active agent raw material into the crusher housing 2 through the feeding hopper 5. After the raw material enters the crushing space, it is fully crushed under the cutting action of the cutter disc 76 and the impact and friction of the fixed teeth 74. During the process, the raw material particles move towards the discharge screen plate 77 under the combined action of centrifugal force and gravity. Particles that meet the particle size requirements pass through the screen holes of the discharge screen plate 77 and are discharged through the discharge port 6 at the bottom of the crusher housing 2. Particles that do not meet the size requirements continue to circulate and be crushed in the crushing space. When maintenance and cleaning of the equipment are required, the operator opens the sealing door 4 and pulls the fixing ring 71 out from the inside of the slide groove 73. At this time, only the cutter disc 76 remains inside the crusher housing 2. Then, the inside of the crusher housing 2 and the inside of the cutter disc 76 can be rinsed directly with cleaning fluid and water. After rinsing, the water will be discharged through the discharge port 6. When it is necessary to replace the discharge screen plate 77 to meet the requirements of different particle sizes, by pulling the handle 83 on the discharge screen plate 77, the discharge screen plate 77 will slide outward along the connecting groove 81 of the fixing ring 71. At this time, the locking block 85 is squeezed by the edge of the locking groove 82, causing the locking block 85 to slide into the limiting groove 84. At the same time, the limiting plate 86 moves synchronously and compresses the spring 87, thereby causing the upper part of the locking block 85 to disengage from the locking groove 82. After the discharge screen plate 77 is completely disengaged from the connecting groove 81, Cleaning or replacement can be performed immediately. During reinstallation, align the discharge screen plate 77 with the connecting groove 81 and push it in. The locking block 85 is compressed by the edge of the connecting groove 81, which compresses the compression spring 87. When the locking block 85 moves to the locking groove 82, the compression spring 87 resets and pushes the locking block 85, so that its upper part is locked into the locking groove 82, thus achieving a stable connection of the discharge screen plate 77. This facilitates the individual replacement and cleaning of the discharge screen plate 77, and different particle size crushing and discharge requirements can be met by replacing the discharge screen plate 77, improving the practicality of the device.
