Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly plasticizer production technology, and in particular to a dehydration device for producing environmentally friendly plasticizers. Background Technology

[0002] Plasticizers, also known as plasticizers, are substances that increase the plasticity of polymer compounds or materials. The most commonly used plasticizer is epoxidized soybean oil. Epoxidized soybean oil is a light yellow, viscous, oily liquid at room temperature, insoluble in water, and has a boiling point higher than water. It is an internationally recognized chemical processing aid used in food packaging materials.

[0003] According to a Chinese patent document (authorization announcement number: CN217764260U), a dehydration device for producing environmentally friendly plasticizers ensures the heating time and effect of the plasticizer, resulting in good dehydration, ease of use, and more thorough dehydration. It includes a base plate, a water tank, a support frame, a drain pipe, and a heater. The water tank is fixedly mounted on the upper part of the base plate via the support frame. The water tank has an internal chamber and an opening at the top. The drain pipe is installed at the lower part of the water tank and has a valve. The heater is fixedly mounted on the right side of the water tank, with its output end located within the chamber. It also includes a dehydration tank, a feed pipe, a discharge pipe, a moving device, a vacuum device, and a stirring device. The moving device is mounted on the base plate, and the dehydration tank is mounted on the moving device. The dehydration tank has an internal cavity. The feed pipe is installed at the upper part of the dehydration tank, and the discharge pipe is installed at the lower part.

[0004] However, the above solution still has the following shortcomings when implemented:

[0005] The existing equipment uses a single dehydration tank design, which limits the dehydration efficiency and makes it difficult to meet the growing demand for large-scale production. In the single-tank dehydration mode, the processing capacity per batch is limited, and the frequent loading and unloading operations consume a lot of time and labor costs, which restricts the improvement of production efficiency.

[0006] In terms of dehydration effect, the heating method of the existing device has defects. It relies on water in the water tank to indirectly heat the dehydration tank, which has low heat transfer efficiency. In terms of environmental performance, the existing device also needs to be improved. The wastewater generated during the dehydration process is not treated well and does not meet strict environmental standards, which increases the environmental compliance risk of enterprises.

[0007] Therefore, we propose a dehydration device for producing environmentally friendly plasticizers. Utility Model Content

[0008] The purpose of this utility model is to overcome the shortcomings of the existing technology. To achieve the above objective, this utility model adopts the following technical solution:

[0009] A dehydration device for producing environmentally friendly plasticizers includes an installation box with a sealing groove on its inner wall. Connecting plates are installed at the four corners of the installation box, and positioning rods are installed on each of the four connecting plates. Two guide plates are symmetrically arranged on both sides and at the bottom of the installation box. A discharge port is provided between two adjacent guide plates, and a drainage filter assembly is provided at the bottom of each of the two discharge ports. The drainage filter assembly is used to discharge and filter the water after dehydration.

[0010] The top of the mounting box is also equipped with a double-barrel dehydration structure, which is used for high-speed rotation to dehydrate.

[0011] The front of the mounting box is provided with two drying components, which are used to assist in dehydration during the dehydration process of the dual-barrel dehydration structure.

[0012] As a preferred embodiment of this utility model, the dual-barrel dehydration structure includes an integrated mounting cover plate, with sliding blocks installed at each of the four corners of the integrated mounting cover plate, and each of the four sliding blocks having a connecting hole. A sealing plate is also provided around the bottom of the integrated mounting cover plate.

[0013] As a preferred embodiment of this utility model, the top of the integrated mounting cover is further provided with a bearing seat, a rotating rod is installed inside the bearing seat, a first pulley is sleeved on the rotating rod, a drive motor is provided at the top of the rotating rod, a second pulley is provided on the right side of the first pulley, a bearing rotating assembly is provided on the second pulley, a connecting belt is provided between the second pulley and the first pulley, and a centrifugal dehydration tank is provided at the bottom of both the bearing rotating assembly and the rotating rod.

[0014] As a preferred embodiment of this utility model, the integrated mounting cover is connected to the positioning rod of the mounting box through the connecting hole of the sliding block, thereby realizing positioning and installation. The sealing plate is inserted into the sealing groove to form a seal. The back side of the integrated mounting cover is also connected to a rotating lifting structure.

[0015] As a preferred embodiment of this utility model, the drainage filter assembly includes an installation pipe, a connecting pipe at the top of the installation pipe, a connecting threaded component inside the installation pipe, an installation component at the bottom of the connecting threaded component, and a filter element inside the installation component.

[0016] As a preferred embodiment of this utility model, the connecting pipe is connected to the outlet, the guide plate is used to guide the extracted water to the outlet, the water entering the connecting pipe will be filtered by the filter element and then discharged, the mounting component is threadedly connected to the mounting pipe through the connecting thread, and a water tank is placed at the bottom of the two drainage filter components for water recovery.

[0017] As a preferred embodiment of this utility model, the drying assembly includes a mounting frame, and a plurality of heating rods are provided inside the mounting frame and on the back side. A fan seat is provided on the front of the plurality of heating rods, and a filter screen is provided on the front of the fan seat.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention employs a double-barrel dewatering structure, where a drive motor drives two centrifugal dewatering barrels to rotate synchronously at high speed via a rotating rod, pulley, and connecting belt. Compared to traditional single-barrel dewatering devices, it can process twice the amount of material at a time, greatly shortening the production cycle, meeting the needs of large-scale production, and effectively improving production efficiency.

[0020] The dehydration effect is better. While the double-barrel dehydration is in progress, two drying components are set on the front. The heating rods in the drying components generate heat, and the fan blows hot air towards the dehydration barrel, which accelerates the vaporization of water in the plasticizer. This complements the centrifugal dehydration effect, making the plasticizer dehydration more thorough, improving product purity, and ensuring the quality of environmentally friendly plasticizers.

[0021] The integrated mounting cover is easy to seal and install. It is connected to the positioning rod of the mounting box through the connecting holes of the four corner sliding blocks, making installation simple and precise. The bottom sealing plate is inserted into the sealing groove to form a good seal, preventing water vapor leakage during the dehydration process, ensuring a stable dehydration environment, and avoiding water vapor corrosion to other parts of the equipment, thus extending the service life of the equipment.

[0022] The drainage filtration function is comprehensive, and the drainage filtration components are reasonably designed. The installation pipe, connecting pipe, connecting threaded parts, installation parts and filter element work together. The guide plate introduces the water produced by dehydration into the connecting pipe, and after being filtered by the filter element, it is discharged, effectively removing impurities in the water and preventing impurities from flowing back and contaminating the plasticizer. The installation parts are threadedly connected to the installation pipe, which makes it easy to disassemble and replace the filter element, ensuring stable filtration effect. In addition, the bottom water tank can recycle the filtered water, realizing the recycling of water resources, which is in line with the concept of environmental protection.

[0034] Example

[0035] like Figure 1-6 As shown, this utility model provides a technical solution: This utility model innovatively adopts a double-barrel dewatering structure. The core of this design lies in the efficient power transmission of the drive motor 58. After the drive motor 58 starts, its output shaft drives the rotating rod 56 to rotate at high speed. The first pulley 57 on the rotating rod 56 rotates synchronously. Since the first pulley 57 is connected to the second pulley 59 on the right side through a connecting belt 511, according to the belt drive principle, the second pulley 59 will also rotate. The bearing rotating assembly 510 is installed on the second pulley 59. Centrifugal dewatering barrels 512 are respectively provided at the bottom of the rotating rod 56 and the bearing rotating assembly 510. In this way, the two centrifugal dewatering barrels 512 can rotate synchronously at high speed under the drive of the drive motor 58. Compared with the traditional single-barrel dewatering device, this device can process twice the amount of material at one time.

[0036] By using belt drive, the power of the drive motor 58 is stably transmitted to the two centrifugal dewatering tanks 512, realizing synchronous high-speed operation of the two tanks. Belt drive has the advantages of smooth transmission, simple structure, low cost and shock absorption, ensuring the consistency and stability of the rotation speed of the two dewatering tanks, so that the material can be quickly dewatered under the action of centrifugal force, thereby improving the processing capacity and production efficiency.

[0037] Based on the dual-barrel high-speed centrifugal dehydration, the two drying components located on the front of this device play an important auxiliary role in dehydration. After the heating rod 82 inside the drying component is connected to the power supply, electrical energy is converted into heat energy, generating a large amount of heat. The fan base 83 is installed on the front of the heating rod 82. When the fan base 83 is started, it will quickly blow the hot air generated by the heating rod 82 towards the dehydration barrel. Under the action of centrifugal force, some of the water in the plasticizer will be thrown out, but some water will still adhere to the plasticizer due to intermolecular forces. The blowing of hot air can increase the temperature of the plasticizer and accelerate the vaporization rate of water. At the same time, the flow of hot air carries away water vapor, reducing the concentration of water vapor in the dehydration barrel. According to the principle of mass transfer, this is conducive to the further vaporization of water in the plasticizer and diffusion into the air. In combination with the centrifugal dehydration, the plasticizer is dehydrated more thoroughly. After this dual dehydration process, the water content in the plasticizer is greatly reduced, and the purity of the product is significantly improved, thereby ensuring the quality of the environmentally friendly plasticizer and making it more advantageous in terms of performance and stability.

[0038] Using the principles of heat transfer and mass transfer, the heat generated by the heating rod 82 is transferred to the plasticizer through hot air, allowing the moisture to obtain sufficient energy to vaporize; the fan base 83 promotes the flow of hot air, reduces the water vapor concentration, breaks the gas-liquid balance, promotes the continuous vaporization and diffusion of moisture in the plasticizer, enhances the dehydration effect, and improves product quality; the filter screen 84 is used to block dust and prevent dust from entering.

[0039] The integrated mounting cover 51 greatly facilitates the installation and maintenance of the equipment while ensuring good sealing. During installation, simply align the connecting holes 53 on the sliding blocks 52 at the four corners of the integrated mounting cover 51 with the positioning rods 4 on the connecting plates 3 at the four corners of the mounting box 1, and then gently lower it to achieve initial positioning. This positioning method is simple and intuitive, and even inexperienced operators can quickly complete the installation, greatly saving installation time. Moreover, accurate positioning ensures greater stability of the equipment during operation and reduces vibration and wear caused by installation deviations. After installation, the sealing plates 54 around the bottom of the mounting cover will be tightly inserted into the sealing grooves 2 on the inner wall of the mounting box 1. The cooperation between the sealing grooves 2 and the sealing plates 54 forms an effective sealing barrier, preventing water vapor from leaking from the connection between the mounting cover and the mounting box 1 during the dehydration process. Water vapor leakage not only affects the dehydration effect but may also damage the surrounding environment and other components, such as causing metal parts to rust and corrode, reducing the service life of the equipment. Good sealing performance ensures a stable dehydration environment, providing a guarantee for efficient dehydration, while also reducing equipment maintenance costs and repair frequency.

[0040] Precise positioning and installation are achieved by using the sliding block 52 to connect the hole 53 and the positioning rod 4. The operation is simple and reliable. The plug-in structure of the sealing plate 54 and the sealing groove 2, based on the physical principle of tight fit, prevents water vapor leakage, maintains a stable dehydration environment, protects equipment components, and extends the service life of the equipment.

[0041] The drainage filter assembly of this utility model is scientifically and rationally designed, with all components working together to achieve efficient drainage and filtration functions. During the dehydration process, the water released from the plasticizer flows under gravity along the guide plates 6 symmetrically arranged on both sides of the bottom of the mounting box 1. The special shape and position design of the guide plates 6 can accurately guide the water to the outlet 7 between two adjacent guide plates 6. The connecting pipe 92 connected below the outlet 7 introduces the water into the mounting pipe 91. The connecting threaded part 94 inside the mounting pipe 91 is connected to the mounting part 93 at the bottom by threads. This connection method is both firm and easy to disassemble. The filter element 95 set inside the mounting part 93 is the key part of the entire drainage filter assembly. It is made of special filter material and has tiny... With its porous structure, when water passes through the filter element 95, impurities such as solid particles and unreacted chemicals are intercepted, while water molecules can pass through smoothly, thus achieving effective separation of water and impurities. The filtered water is discharged from the bottom of the installation pipe 91 and flows into a water tank placed at the bottom of the drainage filter assembly for recycling. When the filter element 95 has been used for a period of time and the filtration effect decreases due to the accumulation of impurities, simply rotate the installation part 93 to unscrew it from the connecting thread part 94 to easily replace the filter element 95, ensuring that the drainage filtration function remains stable and effective. This design not only prevents impurities from flowing back and causing secondary pollution to plasticizers, but also realizes the recycling of water resources, which is in line with the concept of modern environmentally friendly production.

[0042] Based on the principle of gravity diversion, the guide plate 6 directs water to the outlet 7; the pore sieving principle of the filter element 95 separates water from impurities; the threaded connection and detachable structure facilitates the replacement of the filter element 95, ensuring stable drainage filtration function, realizing water resource recycling, and meeting environmental protection requirements.

[0043] Work process summary

[0044] Feeding stage: The environmentally friendly plasticizer to be dehydrated is added to the two centrifugal dehydration tanks 512 in a suitable manner.

[0045] Dehydration stage: Start the drive motor 58, which drives the rotating rod 56, pulley and connecting belt 511 to rotate, so that the two centrifugal dehydration tanks 512 rotate synchronously at high speed for preliminary centrifugal dehydration. At the same time, start the drying component, the heating rod 82 heats up, and the fan seat 83 blows hot air toward the dehydration tank to help accelerate the vaporization of water in the plasticizer and enhance the dehydration effect.

[0046] Drainage and filtration stage: During the dehydration process, the dehydrated water enters the connecting pipe 92 through the outlet 7 under the action of the guide plate 6, and then flows into the bottom water tank for recycling after being filtered by the filter element 95 in the installation pipe 91.

[0047] Maintenance and cleaning phase: When it is necessary to maintain the equipment or replace the filter element 95, the rotating lifting structure 10 on the back side of the integrated mounting cover 51 can be used to raise and rotate the mounting cover, which facilitates the inspection, cleaning and maintenance of the dehydration tank and other components. If the filter element 95 needs to be replaced, the mounting part 93 can be unscrewed directly for operation.

[0048] Feeding stage: After dehydration is completed, stop the drive motor 58 and the drying component, and use the rotating lifting structure 10 (refer to the electric turntable, support plate, servo motor, lead screw, slider and connecting plate in the prior art of the rotating lifting structure 10 in announcement number CN217764260U) to lower the mounting cover, open the centrifugal dehydration tank 512, and take out the dehydrated environmentally friendly plasticizer for subsequent processing.
