Description

Technical Field

[0001] This utility model relates to the field of alkali material processing, and more specifically, to an alkaline raw material crushing device. Background Technology

[0002] Alkali materials, especially sodium hydroxide, are highly alkaline and corrosive. They are widely used as acid neutralizers, complexing masking agents, precipitants, precipitate masking agents, color developers, saponifying agents, peeling agents, and detergents. However, they corrode fibers, skin, glass, and ceramics. Dissolving or diluting concentrated solutions releases heat; neutralization reactions with inorganic acids also generate significant heat and produce corresponding salts. In production and operation, sodium hydroxide is often pulverized into powder to enhance its effectiveness. Because most alkali materials are hygroscopic, they rapidly absorb moisture from the air when exposed, affecting the feeding and discharging efficiency of equipment. Utility Model Content

[0003] The main purpose of this utility model is to provide an alkaline raw material crushing device to solve the problem in the prior art where the deliquescence of alkaline materials affects the feeding and discharging efficiency of the equipment.

[0004] To achieve the above objectives, this utility model provides an alkaline raw material pulverizing device, comprising a storage silo with a sealed cavity, a feeding structure and a discharging structure on the storage silo, both of which are connected to the sealed cavity, a first valve body on the feeding structure and a second valve body on the discharging structure; a pulverizing component connected to the storage silo via the discharging structure; and a discharging component connected to the pulverizing component.

[0005] Furthermore, the alkaline raw material crushing device also includes a stirring assembly, at least part of which is located inside a sealed cavity, and the stirring assembly stirs the alkaline raw material located inside the sealed cavity.

[0006] Furthermore, the stirring assembly includes a stirring shaft located inside a sealed cavity to stir the alkaline raw material; and a driving component disposed on the storage silo, which drives the stirring shaft to rotate.

[0007] Furthermore, the alkaline raw material crushing device also includes a feed hopper, which is connected to a storage hopper.

[0008] Furthermore, the alkaline raw material crushing device also includes a feed pipe, and the feed hopper is connected to the storage hopper through the feed pipe, and the feed pipe and the storage hopper are detachably connected.

[0009] Furthermore, the crushing assembly includes a crushing shell, the feed end of which is connected to a storage bin, and the discharge end of which is connected to a discharge assembly; and a crushing element, which is disposed inside the crushing shell and crushes the alkaline raw material.

[0010] Furthermore, the pulverizing assembly also includes a refrigeration system disposed within the pulverizing housing; and / or the pulverizing housing is volute-shaped.

[0011] Furthermore, the crushing assembly also includes a filter screen, which is disposed at the discharge end of the crushing housing.

[0014] By applying the technical solution of this utility model, the following technical effects are achieved:

[0015] The alkali material is placed in a sealed cavity inside the storage silo. The sealed cavity is only connected to the outside world through the first valve body and the second valve body.

[0024] To address the problem of alkaline materials affecting the feeding and discharging efficiency of equipment due to deliquescence in existing technologies, this application provides an alkaline raw material pulverizing device.

[0025] See Figure 1 and Figure 2 The alkaline raw material crushing device includes a storage bin 10, a crushing component 20, and a discharge component 30. The storage bin 10 has a sealed cavity 11. The storage bin 10 is provided with a feeding structure and a discharge structure, both of which are connected to the sealed cavity 11. The feeding structure is provided with a first valve body 12, and the discharge structure is provided with a second valve body 13. The crushing component 20 is connected to the storage bin 10 through the discharge structure, and the discharge component 30 is connected to the crushing component 20.

[0026] The alkali material is placed in a sealed cavity 11 within the storage silo 10. The sealed cavity 11 is only connected to the outside world through the first valve body 12. It is only possible to connect to the outside world during the feeding and discharging processes. The second valve body 13 controls the entry of the alkali material into the crushing assembly 20 and the discharging assembly 30. This maximizes the sealing of the storage silo 10, reduces the connection between the storage silo 10 and the outside world, isolates the outside air, and avoids poor feeding caused by the deliquescence of the alkali material. This improves the efficiency of large-scale, continuous feeding of alkali material and reduces the deliquescence of the alkali material during processing.

[0027] In this application, the alkaline raw material crushing device also includes a stirring assembly 40, at least a portion of which is located within the sealed cavity 11. The stirring assembly 40 stirs the alkaline raw material located within the sealed cavity 11.

[0028] In this application, the stirring assembly 40 includes a stirring shaft 41 and a driving component 42. The stirring shaft 41 is located in the sealed cavity 11 to stir the alkaline raw material. The driving component 42 is disposed on the storage bin 10 and drives the stirring shaft 41 to rotate.

[0029] Specifically, the stirring assembly 40 stirs the alkali material located in the storage silo 10, which can prevent the alkali material from piling up and bridging in the buffer silo, keeping the alkali material in the storage silo 10 in a loose state, which facilitates the discharge of the alkali material. During the stirring process, the drive unit 42 drives the stirring shaft 41 to stir the alkali material. Preferably, in order to improve the stirring efficiency, blades can be provided on the stirring shaft 41.

[0030] In this application, the alkaline raw material crushing device also includes a feed hopper 14, which is connected to the storage hopper 10.

[0031] In this application, the alkaline raw material crushing device also includes a feed pipe 15, and the feed bin 14 is connected to the storage bin 10 through the feed pipe 15, and the feed pipe 15 and the storage bin 10 are detachably connected.

[0032] Specifically, to further improve the sealing effect of the sealing cavity 11, the feeding structure should be set as small as possible, but this will affect the feeding efficiency. In order to improve the feeding efficiency, an additional feeding hopper 14 is set in connection with the storage hopper 10. The feeding hopper 14 is funnel-shaped, which can facilitate the addition of alkali material into the storage hopper 10.

[0033] Meanwhile, the feed pipe 15 connects the feed hopper 14 and the storage hopper 10, and the feed pipe 15 is designed to be detachable, allowing for easy installation and disassembly of the feed hopper 14. When no additional raw materials are needed, the storage hopper 10 can be disassembled. When there are multiple alkaline raw material crushing devices, these devices can share a single feed hopper 14, reducing overall costs.

[0034] In this application, the crushing assembly 20 includes a crushing shell 21 and a crushing element 22. The feed end of the crushing shell 21 is connected to the storage bin 10, and the discharge end of the crushing shell 21 is connected to the discharge assembly 30. The crushing element 22 is disposed inside the crushing shell 21 and crushes the alkaline raw materials.

[0035] Specifically, the crushing shell 21 forms a crushing space, where the alkali material is further crushed by the crushing components 22 disposed within the crushing shell 21. The alkali material is crushed into powder, making it easier for the discharge assembly 30 to collect it. The crushing is carried out by a fixed-length disc on the inner wall of the crushing shell 21 and the crushing components 22, which act as a rotor disc. The rotor disc is driven to rotate by a motor, and its rapid rotation generates a large shearing force, crushing the caustic soda flakes that enter the crusher.

[0036] In this application, the pulverizing assembly 20 also includes a cooling system 23, which is disposed within the pulverizing housing 21. Since a large amount of heat is generated during the pulverizing process, and the alkali material may deform due to heat, the cooling system 23 is disposed within the pulverizing housing 21 to cool the material and reduce the likelihood of heat deformation affecting processing.

[0037] In this application, the crushing shell 21 is volute-shaped. The volute structure enhances the air-cooling effect inside the crushing chamber, thereby improving the heat dissipation of the crushing chamber and reducing the occurrence of processing problems caused by heat deformation of the alkali material.

[0038] In addition, the cooling pipes of the refrigeration system 23 are coiled inside the volute structure, resulting in better cooling performance and preventing clumping.

[0039] In this application, the crushing assembly 20 also includes a filter screen 24, which is disposed at the discharge end of the crushing housing 21.

[0040] Specifically, the filter screen 24 serves as a filter to screen the alkali material after it has been crushed by the crushing component 20. The alkali powder that can pass through the filter screen 24 meets the processing requirements, while the powder that cannot pass through the filter screen 24 remains in the crushing component 20 for further crushing until the processing requirements are met.

[0041] In this application, the filter screen 24 and the crushing housing 21 are detachably connected. This detachable connection facilitates the replacement and maintenance of the filter screen 24. When the filter screen 24 becomes clogged or the required particle size of the alkali material changes, the problem can be solved by replacing the filter screen 24, thus simplifying the use and maintenance of the equipment.

[0042] In this application, the discharge assembly 30 includes a discharge bin 31, a negative pressure assembly 32, and a filter bag 33. The discharge bin 31 is connected to the crushing assembly 20. The discharge bin 31 has a discharge structure and a vent hole. The negative pressure assembly 32 is connected to the vent hole. The filter bag 33 divides the interior of the discharge bin 31 into a discharge section and an exhaust section. The discharge structure is located on the discharge section, and the vent hole is located on the exhaust section.

[0043] Specifically, after the pulverized alkali material enters the discharge hopper 31, along the direction of airflow, the air and powder will come into contact with the filter bag 33 first. The alkali material is blocked by the filter bag 33, adhering to the surface of the filter bag 33 or falling into the discharge section, while the air is discharged through the exhaust section. By setting a negative pressure device, the negative pressure component 32 provides negative pressure attraction throughout the process, which can accelerate the speed of the pulverized alkali material passing through the filter screen 24 and prevent the material from depositing on the outer shell of the pulverizer.

[0044] To facilitate powder collection, a discharge airlock is installed on the discharge structure to collect the alkali material at regular intervals. To reduce the accumulation of alkali powder on the filter bag 33, a vibrating cylinder is installed on the filter bag 33 to shake the filter bag 33 at regular intervals, dislodging the alkali powder adhering to the filter bag 33. The negative pressure component 32 is a blower.

[0045] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0046] 1. The alkali material is placed in the sealed cavity 11 inside the storage silo 10. The sealed cavity 11 is only connected to the outside through the first valve body 12 and the second valve body 13. It is only possible to connect with the outside during the feeding and discharging process. This can maximize the sealing of the storage silo 10, reduce the connection between the storage silo 10 and the outside, isolate the outside air, and avoid the poor feeding caused by the deliquescence of the alkali material, thereby improving the efficiency of large-scale and continuous feeding of alkali material.

[0047] 2. Since a large amount of heat is generated during the crushing process, and the alkali material may deform due to heat, a cooling system 23 is installed inside the crushing shell 21. This cooling system 23 lowers the temperature and reduces the impact of heat deformation on processing. The volute structure enhances the air-cooling effect within the crushing chamber, further improving heat dissipation and minimizing the impact of heat deformation on processing.

[0048] 3. After the pulverized alkali material enters the discharge hopper 31, along the direction of airflow, the air and powder will come into contact with the filter bag 33 first. The alkali material is blocked by the filter bag 33, adhering to the surface of the filter bag 33 or falling into the discharge section, while the air is discharged through the exhaust section. By setting a negative pressure device, the negative pressure component 32 provides negative pressure attraction throughout the process, which can accelerate the speed of the pulverized alkali material passing through the filter screen 24 and prevent the material from depositing on the outer shell of the pulverizer.
