Description

Technical Field

[0001] This application relates to the field of calcium and zinc stabilizer treatment technology, specifically a calcium and zinc stabilizer airflow pulverizing device. Background Technology

[0002] Calcium-zinc stabilizers, as environmentally friendly heat stabilizers, are widely used in various plastic products such as polyvinyl chloride (PVC) to effectively prevent degradation and discoloration of plastics caused by heat and light during processing and use. In the production process of calcium-zinc stabilizers, pulverization is a crucial step, as its effectiveness directly affects the product's specific surface area, dispersibility, compatibility with the plastic matrix, and overall performance.

[0003] Currently, air jet milling technology is widely used in the pulverization and processing of calcium and zinc stabilizers due to its advantages such as high pulverization efficiency, uniform product particle size, and low pollution. Air jet milling devices use high-speed airflow to cause material particles to collide and rub against each other to achieve ultrafine pulverization. Theoretically, it can pulverize calcium and zinc stabilizers to a particle size range of several micrometers to tens of micrometers, meeting the high standard requirements of plastic processing.

[0004] For example, patent CN222287531U discloses a calcium-zinc stabilizer airflow pulverizing device. This patent uses a high-pressure nozzle to generate a spiral airflow in the crushing inner cylinder to crush the material. After the qualified powder enters the cavity through the filter holes in the cylinder wall, it is blown downwards to the annular exhaust chamber by switching the airflow path, thereby accelerating the powder to be discharged from the discharge hole and completed.

[0005] However, in actual production, calcium-zinc stabilizers, as inorganic salt complexes, have strong hygroscopic properties and easily absorb moisture from the air during storage and transportation. When calcium-zinc stabilizers containing a certain amount of moisture enter the air jet mill, they are prone to agglomeration and clumping in the high-speed airflow, forming large particle aggregates, which greatly reduces the pulverization effect. Secondly, materials containing moisture are prone to adhering to the inner wall of the pulverizing chamber, pipes, and classifier surface during the pulverization process, causing equipment blockage and affecting the stability of continuous production. Furthermore, the presence of moisture will lead to a wider particle size distribution and reduced uniformity of the product, and some products will fail to meet quality requirements due to insufficient pulverization.

[0006] Therefore, it is necessary to provide a calcium-zinc stabilizer airflow pulverizer to solve the above problems.

[0007] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0008] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a calcium-zinc stabilizer airflow pulverizing device, which solves the technical problem of low pulverizing efficiency and poor effect in the airflow pulverizing process caused by the calcium-zinc stabilizer absorbing moisture and agglomerating.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] like Figures 1-3As shown, this utility model provides a calcium-zinc stabilizer airflow pulverizing device. This device is mainly installed in the calcium-zinc stabilizer production workshop and is used to pulverize the calcium-zinc stabilizer raw materials into fine powder that meets the requirements. Specifically, the pulverizing device includes an airflow pulverizing device 1. In this application, the airflow pulverizing device 1 can be a fluidized bed airflow pulverizing device, a disc airflow pulverizing device, or a target airflow pulverizing device in the prior art, and is used to pulverize materials.

[0034] Furthermore, a feeding section 2 is provided on one side of the airflow pulverizer 1 for feeding materials, and a discharge section 3 is provided at the other end of the airflow pulverizer 1 to facilitate the discharge of the crushed calcium-zinc stabilizer for collection or the next process.

[0035] In order to effectively pre-treat the calcium-zinc stabilizer to be crushed, the feeding section 2 includes a support 20 fixedly installed at the feeding end of the airflow pulverizer 1. A temporary storage tank 21 is fixedly installed inside the support 20 by bolts. The temporary storage tank 21 has a cylindrical structure. At the same time, a feeding hopper 22 is fixedly installed on one side of the support 20. The feeding hopper 22 is designed with a funnel shape to facilitate feeding. The output end of the feeding hopper 22 is connected to the inside of the temporary storage tank 21, so that the calcium-zinc stabilizer to be crushed can be smoothly introduced into the temporary storage tank 21 for pre-treatment through the feeding hopper 22.

[0036] In order to transport the pretreated material to the crushing device, an outlet 23 is provided at the tapered part at the lower end of the temporary storage tank 21. The outlet 23 is connected to the inlet of the air jet crushing device 1 through the conveying pipe. In this way, the pretreated calcium-zinc stabilizer can enter the air jet crushing device 1 through the outlet 23 for subsequent fine crushing.

[0037] To prevent the calcium-zinc stabilizer from clumping due to high moisture content during the crushing process, such as... Figures 2-5 As shown, an anti-caking component 26 is provided inside the temporary storage tank 21. The anti-caking component 26 includes a motor 272 fixedly installed at the upper center of the temporary storage tank 21. The output shaft of the motor 272 passes through the top of the temporary storage tank 21 and enters its interior through a mechanical seal. A connecting plate 261 is fixedly installed on the output shaft of the motor 272. The connecting plate 261 is a circular steel plate, and multiple sets of crushing rods 267 are evenly fixed around it. Multiple sets of blades 273 are fixedly installed on the outer side of the crushing rods 267. The blades 273 are made of wear-resistant hard alloy material. Thus, when the motor 272 is started, the multiple sets of crushing rods 267 can be driven to rotate at high speed inside the temporary storage tank 21 through the connecting plate 261.

[0038] In actual operation, after the calcium-zinc stabilizer enters the storage tank 21 through the feeding hopper 22, the operator starts the motor 272 to drive the crushing rod 267 to rotate. During the rotation, the blade 273 shears and impacts the agglomerated calcium-zinc stabilizer, breaking it into smaller particles. This effectively prevents the problem of the subsequent airflow pulverization effect being affected by the material size being too large.

[0039] It should be noted that the rotation speed of the crushing rod 267 can be adjusted according to the state of the material. A higher rotation speed is used for materials with severe agglomeration, and a normal rotation speed is used for materials with slight agglomeration, which ensures both crushing effect and energy saving.

[0040] In order to dry the calcium-zinc stabilizer simultaneously during the crushing process, a shell 262 is tightly wrapped and fixed to the outside of the temporary storage tank 21. The shell 262 is made of heat insulation material, and a sealed heat storage cavity 269 is formed between the shell 262 and the temporary storage tank 21. At the same time, a hot air blower 271 is fixedly installed on one side of the bottom of the support 20. The output end of the hot air blower 271 is fixedly installed with a pipe 270, which is wrapped with heat insulation material. Its output end is connected to the inside of the heat storage cavity 269. Thus, when the hot air blower 271 is started, the generated hot air can be continuously introduced into the heat storage cavity 269 through the pipe 270, providing a stable heat source for the pretreatment process.

[0041] Meanwhile, multiple sets of through holes 268 are uniformly arranged circumferentially and axially on the outer wall of the temporary storage tank 21. The size of the through holes 268 is smaller than the size of the calcium-zinc stabilizer, so as to prevent the calcium-zinc stabilizer from leaking through the through holes 268.

[0042] The hot air blower 271 can then evenly transfer the heat inside the heat storage chamber 269 to the storage tank 21 through the through hole 268, and gently dry the calcium-zinc stabilizer through convective heat transfer. This achieves the effect of removing excess moisture from the material while crushing, effectively preventing agglomeration caused by moisture during the subsequent airflow crushing process.

[0043] When it is necessary to crush the calcium-zinc stabilizer, the raw material is first fed into the temporary storage tank 21 through the feeding hopper 22. Then, the motor 272 is started to drive the crushing rod 267 to rotate the blade 273 to crush the agglomerated material. At the same time, the hot air blower 271 is started to send hot air into the heat storage chamber 269 through the pipe 270. The heat is evenly conducted into the temporary storage tank 21 through the through hole 268 to dry the material simultaneously.

[0044] After pretreatment, the calcium-zinc stabilizer reaches a suitable degree of dryness and particle size. It then enters the airflow pulverizer 1 through outlet 23 to complete fine pulverization. Throughout the process, crushing and drying work together to solve the problem of agglomeration caused by high moisture content in the calcium-zinc stabilizer, thereby improving product quality and production efficiency.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
