Description

Technical Field

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

[0002] Plasticizers, also known as plasticizers, are widely used polymeric material additives in industry. Adding this substance during plastic processing can enhance its flexibility and make it easier to process, and it can be legally used for industrial purposes. However, after the plasticizer is produced, some contaminants will remain on the inner wall of the reactor. If they are not cleaned properly, they will affect the subsequent reaction activities in the reactor. Moreover, after cleaning the inner wall of the reactor, the cleaning device needs to be removed from the reactor to avoid affecting the addition and reaction of various chemical reagents in the subsequent reactor, and also to avoid the chemical reaction corroding the cleaning device.

[0003] According to a Chinese patent document (authorization announcement number: CN214486874U), a material recovery device for the production of environmentally friendly plasticizers is disclosed, relating to the field of plasticizer production technology, it specifically includes a base, a vertical plate, a support plate, a fixing plate, and a reaction vessel. The reaction vessel is welded to the base, and the vertical plate is fixed to one end of the base. A support plate is set on the upper part of the vertical plate, and a fixing plate is fixedly connected to the surface of the support plate. A motor is fixedly connected to the side of the fixing plate, and a conductive rod is connected to the lower end of the fixing plate. The conductive rod passes through the inner cavity and connects to an electric heating plate. Four nozzles are set around the inside of the reaction vessel, and the nozzles are connected to a feed pipe. A pump is set on the base, and the pump is connected to a solvent tank through a connecting pipe. The solvent tank is set on the back of the reaction vessel. A discharge pipe passes through the side of the reaction vessel, and a valve is set on the discharge pipe. One end of the discharge pipe is connected to a recovery cylinder. A feed pipe passes through the upper part of the reaction vessel. This utility model has a simple structure, is easy to operate, and utilizes the combination of organic solvent and electric heating to achieve good cleaning effect, reduce operating costs, and improve economic benefits.

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

[0005] After cleaning the reaction equipment, the mixed solution is simply collected without effectively treating the impurities in the solution. The mixed solution often contains large and fine particulate impurities. If it is discharged directly or reused, the large particulate impurities may clog the pipes, damage the downstream equipment, and affect the normal operation of production.

[0006] Therefore, we propose a material recycling device for the production of environmentally friendly plasticizers. Utility Model Content

[0007] 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:

[0008] A material recycling device for the production of environmentally friendly plasticizers includes a reaction device body and a temporary storage tank. A recycling pipeline structure is provided between the reaction device body and the temporary storage tank. The recycling pipeline structure is used to transport the mixed solution after cleaning in the reaction device body to the temporary storage tank. A sliding groove is provided inside the temporary storage tank. A large particle interception component is installed inside the sliding groove. A fine filter component is also provided on the right side wall of the sliding groove. The fine filter component is used to finely filter the waste liquid after coarse filtration and then return it to the sliding groove. A discharge component is also provided on the back side of the sliding groove. The discharge component is used to transport the filtered mixed solution to a designated recycling location.

[0009] As a preferred embodiment of this utility model, the recycling pipeline structure includes a recycling pipeline, a first solenoid valve is provided on the recycling pipeline, a connecting chamber is provided at the bottom of the recycling pipeline, and a first pump body is provided at the connection of the connecting chamber.

[0010] As a preferred embodiment of this utility model, the large particle interception component includes a fixed frame, a pull ring is installed on the front of the fixed frame, and a coarse filter screen is provided inside the fixed frame.

[0011] As a preferred embodiment of this utility model, the fine filtration assembly includes a first pipe, a second solenoid valve is installed on the first pipe, a first flange is provided on the right side of the second solenoid valve, a filter pipe is provided at the connection of the first flange, a second flange and a third flange are respectively installed on the left and right walls of the filter pipe, a limiting block is provided on the left side inside the filter pipe, a filter element is provided at the connection of the limiting block, and a rubber limiting ring is installed on the right side of the filter element.

The rubber sealing ring is installed on two connected mounting slots to further seal the gaps at the connection.

[0015] As a preferred embodiment of this utility model, the emission assembly includes an emission pipe, on which a third solenoid valve is installed.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, the device incorporates a large particle interception component and a fine filtration component within a temporary storage tank. The coarse filter of the large particle interception component first intercepts large particulate impurities in the mixed solution, while the fine filtration component further refines the waste liquid after coarse filtration, effectively removing fine particulate impurities. This significantly improves the purity of the recovered material, meeting the purity requirements of different production stages and enhancing product quality.

[0018] The large particle interception component traps large particulate impurities in the temporary storage tank, preventing them from entering subsequent pipelines and equipment.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0032] Example

[0033] like Figure 1-6 As shown, this utility model provides a technical solution: the material recovery device for the production of this environmentally friendly plasticizer mainly consists of a reaction device body 1 and a temporary storage tank 2. The recovery pipeline 31 structure between the two plays a key role in connection and transportation. After the plasticizer production is completed, the reaction device body 1 will have a mixed solution containing unreacted raw materials, reaction by-products and other impurities. The recovery pipeline 31 structure is responsible for transporting these mixed solutions to the temporary storage tank 2 for subsequent processing. The temporary storage tank 2 has an ingenious internal design. The sliding groove 4 accommodates a large particle interception component. The fine filtration component set on the right side wall of the sliding groove 4 and the discharge component on the back side work together to achieve multi-stage filtration and final recovery of the mixed solution, ensuring that the recovered material reaches a certain purity standard and meets the requirements for reuse or subsequent processing.

[0034] The entire device is designed based on the need to separate impurities of different particle sizes in a mixed solution. By setting up components with different functions, impurities are gradually removed through physical filtration to achieve material recovery. The reasonable layout of different components in the temporary storage tank 2 allows the solution to flow in an orderly manner within the tank, passing through each processing stage in sequence to complete the filtration and recovery process.

[0035] The recovery pipeline 31 serves as the channel for transferring the mixed solution from the reaction device body 1 to the temporary storage tank 2. The recovery pipeline 31 acts as the main body, and the first solenoid valve 32 installed on it controls the flow of the solution. When solution needs to be transported, the first solenoid valve 32 opens, allowing the solution to pass through; when transport is not needed, the solenoid valve closes to prevent backflow or leakage. The connecting chamber 33 at the bottom of the recovery pipeline 31 acts as a transition and buffer, ensuring the solution is in a relatively stable state before entering the first pump body 34. The first pump body 34 is the core component providing the transport power, pumping the mixed solution from the reaction device body 1 through the recovery pipeline 31 into the temporary storage tank 2, ensuring the solution can overcome pipeline resistance and successfully complete the transport process.

[0036] The first solenoid valve 32 uses electromagnetic principles to control the opening and closing of the valve, thereby controlling the flow of the solution. The connecting chamber 33, based on fluid mechanics principles, provides a stable inflow environment for the solution and reduces the impact of pressure fluctuations on the pump body. The first pump body 34 generates a pressure difference through mechanical operation, which propels the solution to flow in the pipeline, following the basic principles of fluid transport.

[0037] The large particle interception assembly is a key component in the temporary storage tank 2 for the initial filtration of the mixed solution. The fixed frame 51 serves as the supporting structure for the entire assembly, ensuring the stable installation of the coarse filter screen 53. The pull ring 52 mounted on the front provides a convenient operating interface for the operator. When the coarse filter screen 53 intercepts a certain amount of large particle impurities, affecting the filtration effect, the operator can easily remove the fixed frame 51 from the sliding groove 4 by pulling the pull ring 52 to clean or replace the coarse filter screen 53. The coarse filter screen 53 is the core component for intercepting large particle impurities. It has a specific pore size and is designed according to the common particle size range of impurities in the mixed solution. It can effectively block large particle impurities such as unreacted solid raw material particles and large debris generated by equipment wear, preventing these impurities from entering the subsequent fine filtration assembly and discharge assembly, protecting the equipment and improving the subsequent filtration effect.

[0038] Based on the principle of sieving, the coarse filter 53 filters particles in the mixed solution according to the size of the mesh. Large particles cannot pass through the mesh and are thus intercepted on the coarse filter 53. The pull ring 52 uses the lever principle to facilitate the operator to apply force, making the removal of the fixed frame 51 more convenient and in line with the ergonomic design concept.

[0039] The fine filtration assembly plays a crucial role in the deep purification of the waste liquid after coarse filtration. The first pipe 61 serves as the inlet for the waste liquid to enter the fine filtration assembly, and the second solenoid valve 62 is installed on it to control the inflow of waste liquid. The first flange 63 connects the first pipe 61 and the filter pipe 65 to ensure the sealing and stability of the connection. The internal structure of the filter pipe 65 is complex and critical. The limiting block 67 on the left and the rubber limiting ring 69 on the right work together to limit and clamp the filter element 68. The filter element 68 is the core component of fine filtration. It uses high-precision filter material and can filter out micron-sized or even smaller fine particulate impurities, such as colloids and metal ions, which greatly improves the purity of the solution. The second flange 64 and the third flange 66 are used to connect the filter pipe 65 to other components to ensure the integrity of the entire assembly.

[0040] The second solenoid valve 62 is also based on the electromagnetic control principle to control the entry of waste liquid. The filter element 68 uses the microporous structure and surface adsorption of the filter material to remove fine particulate impurities through sieving and adsorption. The limiting block 67 and the rubber limiting ring 69 cooperate with each other to ensure that the filter element 68 remains stable under the impact of water flow, thus ensuring the stability of the filtration effect.

[0041] The second pipe 611 connected to the third flange 66 further guides the flow of the filtered solution. The fourth flange 610 is installed on the second pipe 611 and connects with other components. The mounting groove 612 opened on the first flange 63, second flange 64, third flange 66, fourth flange 610, and rubber limiting ring 69, together with the rubber sealing ring 613, greatly enhances the sealing performance of the connection. During the connection process, the rubber sealing ring 613 is fitted into the mounting groove 612 to fill the tiny gaps at the connection and prevent solution leakage. The connecting chamber 614 plays the role of collecting and distributing the solution. The second pump body 615 is installed on the front of the connecting chamber 614 to provide power for the filtered solution, enabling it to return to the sliding tank 4 through the return pipe 616 for recirculation filtration or subsequent treatment, ensuring that the filtration effect of the solution reaches the best.

[0042] The mounting groove 612 and the rubber sealing ring 613 utilize the elasticity and sealing properties of rubber to fill gaps and prevent solution leakage, following the sealing principle. The second pump body 615 generates pressure through mechanical operation to drive the solution flow. The design of the connecting chamber 614 and the return pipe 616 is based on the principle of fluid distribution and circulation, enabling the filtered solution to flow and circulate reasonably, thereby improving filtration efficiency.

[0043] The rubber limiting ring 69 is installed in the groove on the inner wall of the filter pipe 65 and fits tightly with the limiting block 67. During the solution filtration process, the water flow will generate an impact force on the filter element 68. If the filter element 68 moves frequently, it will not only reduce the filtration effect, but may also damage the filter element 68. The rubber limiting ring 69 and the limiting block 67 work together to firmly fix the filter element 68 in the filter pipe 65 through friction and mechanical limiting, ensuring its stability under the impact of water flow. The rubber sealing ring 613 is installed on two connected mounting grooves 612. Since there are inevitably small gaps at the flange connection, the rubber sealing ring 613 uses its own elasticity to fit tightly in the mounting groove 612, filling these gaps and preventing the solution from leaking from the connection, thus ensuring the sealing of the entire fine filter assembly and the stability of the filtration process.

[0044] The rubber limiting ring 69 and the limiting block 67 use friction and mechanical limiting principles to restrict the movement of the filter element 68, while the rubber sealing ring 613 fills the gaps based on the elastic deformation characteristics of rubber to achieve a sealing effect, which conforms to the basic principles of sealing and mechanical fixation.

[0045] The discharge assembly is the last link in the entire material recovery device. The discharge pipe 7 is responsible for transporting the mixed solution, after large particle interception and fine filtration, to the designated recovery location. The third solenoid valve 8 is installed on the discharge pipe 7 and controls the discharge of the solution. When the solution reaches the specified filtration standard, the third solenoid valve 8 is opened and the solution is discharged through the discharge pipe 7. When the standard is not met or discharge is not required, the solenoid valve is closed to prevent the solution from being discharged indiscriminately and to ensure the controllability and safety of the recovery process.

[0046] The third solenoid valve 8 controls the opening and closing of the discharge pipe 7 based on the electromagnetic control principle, thereby achieving precise control of the solution discharge and ensuring that the solution is delivered to the designated recovery location at the appropriate time.

[0047] Work process summary

[0048] After the plasticizer production is completed, during the recovery stage of the mixed solution inside the reaction device body 1, the first solenoid valve 32 is opened, the first pump body 34 is started, and the mixed solution is pumped through the recovery pipe 31 and the connecting chamber 33 to the sliding groove 4 of the temporary storage tank 2.

[0049] The mixed solution entering the sliding tank 4 first passes through the large particle interception component. The coarse filter 53 intercepts large particle impurities. The operator can periodically remove the fixed frame 51 by pulling the pull ring 52 to clean the coarse filter 53.

[0050] The waste liquid after coarse filtration flows into the fine filtration component. The second solenoid valve 62 opens, and the waste liquid enters the filter pipe 65 through the first pipe 61. Inside the filter pipe 65, the filter element 68 performs fine filtration on the waste liquid to remove fine particulate impurities. The filtered solution passes through the second pipe 611 and the connecting chamber 614. Under the action of the second pump body 615, it returns to the sliding tank 4 through the return pipe 616 for further filtration.

[0051] When the recycling location is ready for storage, the third solenoid valve 8 on the discharge pipe 7 can be opened. The filtered mixed solution is then transported to the designated recycling location through the discharge pipe 7, completing the entire material recycling process.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
