Abstract
Description
Technical Field
[0001] This utility model relates to the field of PVC stabilizer preparation technology, specifically a mixing and stirring device for PVC stabilizer preparation. Background Technology
[0002] In the production of PVC (polyvinyl chloride) products, PVC stabilizers play a crucial role. They effectively inhibit thermal degradation, oxidative degradation, and photodegradation of PVC during processing and use, thereby improving the performance and service life of PVC products. The quality of PVC stabilizer preparation largely depends on the performance of the mixing equipment.
[0003] Most currently used mixing and stirring equipment is not conducive to mixing raw materials. It's impossible to scrape off the raw materials adhering to the inner wall of the mixing drum, and it's impossible to observe the mixing process inside the drum. During use, the inconvenience in mixing raw materials can lead to uneven mixing, resulting in poor mixing effects and low-quality PVC stabilizers, thus reducing the equipment's practicality. Furthermore, the inability to scrape off the raw materials adhering to the inner wall of the mixing drum can cause the raw materials to adhere to the inner wall or form scale, leading to localized overheating and uneven reaction, resulting in poor mixing effects. Therefore, the mixing effect of this equipment is inadequate. The inability to directly observe the mixing process inside the mixing drum can lead to abnormalities such as damaged mixing blades, material clumping, or foreign matter contamination. These issues are difficult for staff to observe and address promptly, resulting in poor practicality and mixing efficiency of the equipment. Furthermore, the difficulty in discharging the mixed material can cause some material to remain inside the mixing drum after discharge, leading to resource waste. Discharging difficulties also prolong the production cycle and reduce output per unit time, resulting in poor discharge efficiency and effectiveness of the mixing equipment. Utility Model Content
[0004] The purpose of this invention is to provide a mixing and stirring device for preparing PVC stabilizers, so as to solve the problems mentioned in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing and stirring device for preparing PVC stabilizer, comprising a stirring drum, a stirring observation and wall scraping mechanism at the bottom of the stirring drum, the stirring observation and wall scraping mechanism comprising a motor bracket, a motor bracket fixedly connected to the bottom of the stirring drum, a motor fixedly connected to the inner side of the motor bracket, a motor shaft fixedly connected to the output shaft of the motor via a coupling, the outer side of the motor shaft penetratingly connected to the bottom of the stirring drum, a stirring blade fixedly connected to the outer wall of the motor shaft, a connecting rod fixedly connected to the outer wall of the motor shaft, a scraper fixedly connected to one side of the connecting rod, the outer wall of the scraper fitting against the inner wall of the stirring drum, and a transparent plate fixedly connected to the inside of the stirring drum.
[0006] As a preferred technical solution, the number of motor brackets is two, and the shape of the motor brackets is L-shaped.
[0007] As a preferred technical solution, the number of scrapers is two, and the shape of the scrapers matches the shape of the mixing drum.
[0008] As a preferred technical solution, the inside of the stirring drum is provided with an opening, the shape and size of which match the shape and size of the transparent plate, and the stirring drum is fixedly connected to the transparent plate through the opening.
[0009] As a preferred technical solution, a cover plate is hinged to the top of the stirring drum, a handle is fixedly connected to the top of the cover plate, and a heating element is fixedly connected to the outer wall of the stirring drum.
[0010] As a preferred technical solution, a support leg is fixedly connected to the bottom of the stirring drum, and a base is fixedly connected to the bottom end of the support leg.
[0011] As a preferred technical solution, the bottom of the mixing drum is provided with a discharge mechanism, which includes a discharge pipe, and the bottom of the mixing drum is fixedly connected to the discharge pipe.
[0012] As a preferred technical solution, a valve is fixedly connected to the outer wall of the discharge pipe, and a pump body is fixedly connected to the outer wall of the discharge pipe.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model, through the design of the stirring and observation scraping mechanism, facilitates the mixing of raw materials, allows for observation of the mixing process inside the mixing drum, and scrapes off raw materials adhering to the inner wall of the mixing drum. During use, the motor drives the stirring blades to rotate, mixing the raw materials. Simultaneously, the scraper scrapes off raw materials adhering to the inner wall of the mixing drum and the inner wall of the transparent plate. The transparent plate allows for observation of the mixing process inside the mixing drum, preventing uneven mixing caused by difficulty in mixing the raw materials, thus avoiding poor mixing results and producing PVC stabilizer of varying quality. The absence of poor mixing ensures the practicality of the equipment and prevents the material from adhering to the inner wall of the mixing drum, causing it to stick or form scale, leading to localized overheating, uneven reaction, and poor mixing effect. It also prevents abnormalities such as damaged mixing blades, material clumping, or foreign matter contamination during mixing that cannot be directly observed by staff, making it difficult to take timely measures. This ensures the practicality and mixing effect of the equipment.
[0015] 2. This utility model, through the setting of the discharge mechanism, can facilitate the discharge of the well-mixed PVC stabilizer material from the mixing drum. During use, the discharge pipe is opened by the valve and the pump is started to discharge the material in the mixing drum. This avoids the waste of resources caused by some material remaining in the mixing drum after discharge due to the difficulty in discharging the well-mixed material. Furthermore, the difficulty in discharging will prolong the single production cycle and reduce the output per unit time, thus ensuring the discharge effect and efficiency of the equipment.

Detailed Implementation
[0021] 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.
[0022] Example: Figure 1 As shown, the present invention provides the following technical solution, including a stirring drum 1, a stirring observation and wall scraping mechanism 2 at the bottom of the stirring drum 1, a cover plate 4 hinged to the top of the stirring drum 1, a handle 5 fixedly connected to the top of the cover plate 4, a heating element 6 fixedly connected to the outer wall of the stirring drum 1, a support leg 7 fixedly connected to the bottom of the stirring drum 1, a base 8 fixedly connected to the bottom end of the support leg 7, and a discharge mechanism 3 at the bottom of the stirring drum 1.
[0023] When this mixing equipment is needed to mix PVC stabilizer raw materials, firstly, open the cover plate 4 using handle 5, pour the proportioned raw materials evenly into the mixing drum 1, and then close the cover plate 4. At this time, activate the heating element 6, which activates the resistance wire on the inner wall of the mixing drum 1, raising the temperature inside the mixing drum 1 to a suitable temperature for mixing the PVC stabilizer. Then, the raw materials are mixed using the set stirring observation and scraping mechanism 2. During the mixing process, the operator needs to observe the mixing situation inside the mixing drum 1 using the set stirring observation and scraping mechanism 2. During the mixing process inside the mixing drum 1, the raw materials may adhere to the inner wall of the mixing drum 1 or the inner wall of the transparent plate 207, resulting in uneven mixing and obstructing the clarity of the transparent plate 207, affecting the observation of the workers. At this time, it is necessary to scrape off the raw materials from the inner wall of the mixing drum 1 and the inner wall of the transparent plate 207. The mixing observation scraping mechanism 2 is used to scrape off the raw materials from the inner wall of the mixing drum 1 and the inner wall of the transparent plate 207. After the mixing is completed, the mixed PVC stabilizer material in the mixing drum 1 needs to be discharged. The discharge mechanism 3 is used to discharge the mixed PVC stabilizer material in the mixing drum 1, thereby completing the work.
[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a stirring, observation, and wall-scraping mechanism 2 is provided at the bottom of the stirring drum 1. The stirring, observation, and wall-scraping mechanism 2 includes a motor bracket 201. The motor bracket 201 is fixedly connected to the bottom of the stirring drum 1. A motor 202 is fixedly connected to the inner side of the motor bracket 201. The output shaft of the motor 202 is fixedly connected to a motor shaft 203 via a coupling. The outer side of the motor shaft 203 is connected through to the bottom of the stirring drum 1. A stirring blade 204 is fixedly connected to the outer wall of the motor shaft 203. A connecting rod 205 is fixedly connected to the outer wall of the motor shaft 203. A scraper 206 is fixedly connected to one side of 05. The outer wall of the scraper 206 is in contact with the inner wall of the mixing drum 1. A transparent plate 207 is fixedly connected inside the mixing drum 1. There are two motor brackets 201, and the shape of the motor brackets 201 is L-shaped. There are two scrapers 206, and the shape of the scrapers 206 matches the shape of the mixing drum 1. An opening is provided inside the mixing drum 1. The shape and size of the opening match the shape and size of the transparent plate 207. The mixing drum 1 is fixedly connected to the transparent plate 207 through the opening.
[0025] When mixing raw materials is required, motor 202 is started, causing motor shaft 203 to rotate. Motor shaft 203 then drives stirring blade 204 to rotate, mixing the raw materials. During the mixing process, workers need to observe the mixing inside the mixing drum 1 through a transparent plate 207. During mixing, raw materials may adhere to the inner wall of the mixing drum 1 or the inner wall of the transparent plate 207, causing uneven mixing and obstructing the clarity of the transparent plate, thus affecting observation. In this case, the raw materials on the inner wall of the mixing drum 1 and the inner wall of the transparent plate 207 need to be scraped off. Simultaneously, motor shaft 203 drives connecting rod 205 to rotate, which in turn drives scraper 206 to rotate, continuously scraping the inner wall of the mixing drum 1 and the inner wall of the transparent plate 207 to remove the raw materials, thus completing the scraping process.
[0026] like Figure 1 and Figure 4 As shown, a discharge mechanism 3 is provided at the bottom of the mixing drum 1. The discharge mechanism 3 includes a discharge pipe 301. The discharge pipe 301 is fixedly connected to the bottom of the mixing drum 1. A valve 302 is fixedly connected to the outer wall of the discharge pipe 301. A pump body 303 is fixedly connected to the outer wall of the discharge pipe 301.
[0027] After mixing, the mixed PVC stabilizer material in the mixing drum 1 needs to be discharged. At this time, the discharge pipe 301 is opened through valve 302, and then the pump body 303 is started. The pump body 303 draws the material inside the mixing drum 1 into the pump body 303 through the discharge pipe 301, and then discharges the material inside the pump body 303 through the discharge pipe 301, thus completing the discharge work.
[0028] The working principle of this utility model is as follows: When the mixing equipment is needed to mix PVC stabilizer raw materials, firstly, open the cover plate 4 through the handle 5, pour the proportioned raw materials into the mixing drum 1, and then close the cover plate 4. At this time, start the heating element 6, which activates the resistance wire inside the mixing drum 1, raising the temperature inside the mixing drum 1 to a suitable temperature for mixing PVC stabilizer. Then, start the motor 202, causing the motor shaft 203 to rotate. The motor shaft 203 then drives the stirring blades 204 to rotate, mixing the raw materials. During the mixing process, the operator needs to observe the mixing inside the mixing drum 1. The operator observes the mixing inside the mixing drum 1 through the transparent plate 207, thus completing the observation work. During mixing, the raw materials may adhere to... The inner wall of the mixing drum 1 or the inner wall of the transparent plate 207 can cause uneven mixing and obstruct the clarity of the transparent plate 207, affecting the observation of the staff. At this time, it is necessary to scrape the material off the inner wall of the mixing drum 1 and the inner wall of the transparent plate 207. During mixing, the motor shaft 203 will drive the connecting rod 205 to rotate, and the connecting rod 205 will drive the scraper 206 to rotate, so that the scraper 206 will continuously scrape the inner wall of the mixing drum 1 and the inner wall of the transparent plate 207 to scrape off the material, thereby completing the wall scraping work. After the mixing is completed, it is necessary to discharge the mixed PVC stabilizer material in the mixing drum 1. At this time, the discharge pipe 301 is opened through the valve 302, and then the pump body 303 is started, so that the pump body 303 draws the material inside the mixing drum 1 into the pump body 303 through the discharge pipe 301, and then the pump body 303 discharges the material inside the pump body 303 through the discharge pipe 301, thereby completing the discharge work.
