Description

Technical Field

[0001] The present invention relates to the field of toughening agent production equipment, and specifically to a production equipment for PPS special toughening agent. Background Art

[0002] PPS (polyphenylene sulfide) is a high-performance thermoplastic with excellent mechanical properties, acid and alkali resistance, heat resistance and flame retardancy, and is widely used in the fields of electrical appliances, automobiles, chemical engineering and military industry. However, PPS itself is brittle and needs to be toughened and modified to broaden its application fields. Therefore, the production equipment for PPS special toughening agent and its background technology are particularly important; The production equipment in the prior art does not have the function of adjusting the viscosity of the toughening agent. Therefore, when adjusting the viscosity of the toughening agent, an appropriate amount of water is usually added manually to comprehensively adjust the viscosity. When an excessive amount of water is added, the equipment cannot timely precipitate the liquid. Summary of the Invention

[0003] The present invention provides a production equipment for PPS special toughening agent, which overcomes the deficiencies described in the background art.

[0004] The technical solution adopted by the present invention to solve its technical problems is: A production equipment for PPS special toughening agent includes a toughening agent mixing tank body and an upper cover covering the toughening agent mixing tank body. The toughening agent mixing tank body includes an inner tank and an outer tank sleeved outside the inner tank. There is a cavity for storing liquid between the inner tank and the outer tank, and this cavity communicates outward through a solenoid valve discharge pipe provided at the lower end of the outer side of the outer tank. The inner side of the inner tank is connected to the outer tank through a pressure relief port provided at its lower part; The upper cover is provided with a second motor, an electric push rod, a first connecting pipe, and a second connecting pipe. The electric push rods are arrayed on the side of the toughening agent mixing tank body to drive the opening and closing of the upper cover through the electric push rods. The upper cover is externally connected to a water pump and an air compressor through the first connecting pipe and the second connecting pipe respectively. The second motor is arranged in the middle of the lower end of the upper cover, and a stirring disk is arranged on the output shaft of the second motor. When the upper cover covers the toughening agent mixing tank body, the lower end of the stirring disk abuts against the lower end of the inner side of the inner tank; One side of the pressure relief port close to the stirring disk is covered with a permeable membrane for filtering water. When the upper cover covers the toughening agent mixing tank body and the pressure inside the inner tank is increased by an externally connected air compressor, water will seep out through the permeable membrane and flow into the cavity between the inner tank and the outer tank.

[0005] In a preferred technical solution, a plurality of inner tanks are annularly arrayed on the peripheral surface of the inner tank, and a first motor is arranged on the side of the inner tank. A gear disk on the output shaft of the first motor meshes with...

[0006] In a preferred technical solution, an annular diversion groove is provided at the lower end inside the outer tank, and the solenoid valve discharge pipe is arranged at the corresponding position on the outer surface of the outer tank and the annular diversion groove.

[0007] In a preferred technical solution, the pressure relief port is composed of a through hole and an inclined side. The through hole is arranged obliquely downward, the higher end is communicated with the inside of the outer tank, and the inclined side is arranged on the side of the through hole away from the outer tank, and the inclined side and the edge of the through hole form a flared structure, so that the inner diameter of the through hole near the outer tank is smaller than that of the other side.

[0008] In a preferred technical solution, a pressure relief structure is arranged on the side of the pressure relief port away from the permeable membrane. The pressure relief structure includes a housing, a baffle, and pressure relief closing blades. The baffle is arranged in the middle of the housing, and a gap for fluid to pass through is formed between the baffle and the housing. The pressure relief closing blades cover the baffle, and when the pressure relief closing blades rotate, the gap is covered. The baffle includes three fan-shaped blocks arranged in a rotational array. The gaps are respectively arranged between two adjacent fan-shaped blocks. The pressure relief closing blades include three fan-shaped baffles arranged in a rotational array. The three fan-shaped baffles are rotatably installed on the baffle through a circular plate arranged in the middle of the pressure relief closing blades. The surface of the fan-shaped baffle is inclined. When the pressure relief closing blades are pushed by the fluid, they rotate with the circular plate arranged in the middle as the fulcrum, and the fluid flows through the gap.

[0009] In a preferred technical solution, three arc-shaped grooves are respectively arranged at the corresponding positions of the inner side of the housing and the three pressure relief closing blades. Springs are arranged in the three arc-shaped grooves. The ends of the springs abut against the abutting blocks arranged on the outer sides of the pressure relief closing blades, so that when the pressure relief closing blades rotate, the springs are pushed by the abutting blocks.

[0010] Compared with the prior art, this technical solution has the following advantages: When the upper cover is covered on the toughener mixing tank body and the pressure inside the inner tank is increased by an externally connected air compressor, if there is excess water in the inner tank, which may be added when adjusting the viscosity, these waters will be pushed towards the pressure relief port under the action of the pressure. A permeable membrane is covered on the side of the pressure relief port close to the stirring disc. This permeable membrane allows water to pass through but blocks toughener or other solid particles. Therefore, the excess water will seep out through the permeable membrane and flow into the cavity between the inner tank and the outer tank. This design ensures that even if excessive water is added, it can be precipitated in time through the automatic pressure regulation mechanism, avoiding the influence on the quality of the toughener.

Specific implementation manners

[0022] As Figures 1 to 9 shown, in the present invention, a production device for a PPS special toughener is proposed, which includes a toughener mixing tank body 1 and an upper cover 2 covering the toughener mixing tank body 1. The toughener mixing tank body 1 includes an inner tank 11 and an outer tank 12 sleeved outside the inner tank 11. There is a cavity for storing liquid between the inner tank 11 and the outer tank 12, and this cavity is externally communicated through a solenoid valve discharge pipe 13 arranged at the lower end of the outer side of the outer tank 12. The inner side of the inner tank 11 is connected to the outer tank 12 through a pressure relief port 111 arranged at its lower part; The upper cover 2 is provided with a second motor 21, an electric push rod 22, a first connecting pipe 23, and a second connecting pipe 24. The electric push rods 22 are arranged in an array on the side of the toughening agent mixing tank body 1 to drive the opening and closing of the upper cover 2 through the electric push rods 22. The upper cover 2 is externally connected to a water pump and an air compressor through the first connecting pipe 23 and the second connecting pipe 24 respectively. The second motor 21 is arranged in the middle of the lower end of the upper cover 2, and a stirring disk 211 is arranged on the output shaft of the second motor 21. When the upper cover 2 is covered on the toughening agent mixing tank body 1, the lower end of the stirring disk 211 abuts against the inner side lower end of the inner tank 11; The first connecting pipe 23 is externally connected to a water pump, which is used to inject an appropriate amount of water into the inner tank 11 in the toughening agent mixing tank body 1. This design allows for precise control of the amount of water added by the water pump when it is necessary to reduce the viscosity of the toughening agent, thus avoiding the problem of excessive addition that may be caused by manual addition. When the water pump works, water enters the inner tank 11 through the first connecting pipe 23 and mixes with the toughening agent to achieve the purpose of adjusting the viscosity.

[0023] The second connecting pipe 24 is externally connected to an air compressor, which is used to provide compressed air into the inner tank 11 to increase its internal pressure. This step is particularly important after adjusting the viscosity, especially when it is suspected that an excessive amount of water may have been added. When the air compressor works, compressed air enters the inner tank 11 through the second connecting pipe 24, increasing its internal pressure. This pressure change causes any excess water in the inner tank 11, if added in excess due to improper operation, to seep out through the permeable membrane 113 near the pressure relief port 111.

[0024] The permeable membrane 113 covers the side of the pressure relief port 111 close to the stirring disk 211. Its function is to allow water to pass through under the action of a pressure difference while preventing the toughening agent or other solid particles from passing through. When the internal pressure of the inner tank 11 increases provided by the air compressor, the water is forced through the permeable membrane 113 and flows into the cavity between the inner tank 11 and the outer tank 12. This design ensures that even if an excessive amount of water is added, it can be precipitated in a timely manner through the automatic pressure adjustment mechanism, avoiding the impact on the quality of the toughening agent.

[0025] The side of the pressure relief port 111 close to the stirring disk 211 is covered with a permeable membrane 113 for filtering water. When the upper cover 2 is covered on the toughening agent mixing tank body 1 and the internal pressure of the inner tank 11 is increased by an externally connected air compressor, the water will seep out through the permeable membrane 113 and flow into the cavity between the inner tank 11 and the outer tank 12. And a plurality of 114 are annularly arranged on the circumferential surface of the inner tank 11, and a first motor 14 is arranged on the side of the inner tank 11. The gear disk 141 on the output shaft of the first motor 14 meshes with 114; When the upper cover 2 is placed on the toughener mixing tank body 1 and the pressure inside the inner tank 11 is increased by an externally connected air compressor, if there is excess moisture in the inner tank 11, which may be added during the adjustment of viscosity, this moisture will be pushed towards the pressure relief port 111 under the action of pressure. A permeable membrane 113 is covered on one side of the pressure relief port 111 close to the stirring disc 211. This permeable membrane allows moisture to pass through but blocks the passage of toughener or other solid particles. Therefore, the excess moisture will seep out through the permeable membrane 113 and flow into the cavity between the inner tank 11 and the outer tank 12. This design ensures that even if an excessive amount of water is added, it can be precipitated in a timely manner through the automatic pressure adjustment mechanism, avoiding the impact on the quality of the toughener.

[0026] Furthermore, an annular diversion groove 121 is provided at the lower end inside the outer tank 12. The solenoid valve discharge pipe 13 is arranged at the corresponding position on the outer surface of the outer tank 12 and the annular diversion groove 121. The pressure relief port 111 is composed of a through hole and an inclined side. The through hole is arranged obliquely downward, with the higher end communicating with the inside of the outer tank 12, and the inclined side is arranged on the side of the through hole away from the outer tank 12. The inclined side and the edge of the through hole form a flared structure, so that the inner diameter of the through hole on the side close to the outer tank 12 is smaller than that on the other side. This design not only helps the moisture to pass through the permeable membrane 113 more easily under the action of pressure, but also accelerates the flow of moisture and improves the seepage efficiency. The inclined downward arrangement of the through hole ensures that the moisture can flow smoothly, and the inclined side plays a role in guiding the moisture towards the through hole. In addition, the inner diameter of the through hole on the side close to the outer tank 12 is smaller than that on the other side, which further enhances the flow rate of the moisture and makes the seepage process more efficient; The annular diversion groove 121 is ingeniously designed at the lower end inside the outer tank 12, and its main function is to collect and guide the moisture that seeps out from the inner tank 11 through the permeable membrane 113. This design ensures that the seeped moisture can flow orderly to a specific area, rather than being scattered randomly in the cavity between the outer tank 12 and the inner tank 11.

[0027] Moreover, a pressure relief structure 112 is provided on the side of the pressure relief port 111 away from the permeable membrane 113. The pressure relief structure 112 includes a housing 1121, a baffle 1122, and a pressure relief closing blade 1123. The baffle 1122 is arranged in the middle of the housing 1121. A gap for fluid to pass through is formed between the baffle 1122 and the housing 1121. The pressure relief closing blade 1123 covers the baffle 1122, and when the pressure relief closing blade 1123 rotates, it covers the gap; The baffle 1122 includes three fan-shaped blocks arranged in a rotational array, and the notches are respectively arranged between two adjacent fan-shaped blocks. The pressure relief closing blade 1123 includes three fan-shaped baffles arranged in a rotational array. The three fan-shaped baffles are rotatably mounted on the baffle 1122 through a circular plate arranged in the middle of the pressure relief closing blade 1123. The surface of the fan-shaped baffle is inclined. When the pressure relief closing blade 1123 is pushed by the fluid, it rotates with the circular plate arranged in the middle as the fulcrum, and allows the fluid to flow through the notch. Moreover, three arc-shaped grooves 1211 are respectively arranged at the corresponding positions of the inner side of the housing 1121 and the three pressure relief closing blades 1123. Springs 1212 are arranged in the three arc-shaped grooves 1211. The ends of the springs 1212 abut against the abutting blocks 1231 arranged on the outer sides of the pressure relief closing blades 1123, so that when the pressure relief closing blades 1123 rotate, the abutting blocks 1231 push the springs 1212.

[0028] During the production process of the toughening agent, if the pressure in the inner tank 11 is too high, it may damage the equipment or affect the quality of the toughening agent. Through the design of the pressure relief structure 112, when the pressure exceeds the preset value, the fluid can automatically flow out through the pressure relief port 111, thereby protecting the equipment and ensuring the product quality. In addition, the design of the pressure relief structure 112 also allows automatic closing after the pressure drops, preventing external air or impurities from entering the inner tank 11, and maintaining the purity of the toughening agent and the stability of the production environment.

[0029] The design of the pressure relief port 111 is precisely to solve the key problem in this background technology. When the pressure in the inner tank 11 reaches or exceeds the preset value, the fluid gas or liquid will flow towards the pressure relief port 111 through the permeable membrane 113 or other paths. At this time, the pressure relief closing blade 1123 will be subjected to the thrust of the fluid and start to rotate along the arc-shaped groove 1211 on the inner side of the housing 1121.

[0030] During the rotation process, the abutting block 1231 component on the outer side of the pressure relief closing blade 1123 will interact with the spring 1212. The spring 1212 plays two key roles here: one is to provide a certain resistance to the rotation of the pressure relief closing blade 1123, so that the pressure relief process has a certain threshold; the other is to ensure that after the pressure drops, the pressure relief closing blade 1123 can automatically reset through its elastic restoring force, preventing external air or impurities from entering the inner tank 11.

[0031] When the fluid pressure is large enough to overcome the resistance of the spring 1212, the pressure relief closing blade 1123 will continue to rotate, exposing the notch on the baffle 1122, allowing the fluid to flow out through the notch, so as to achieve the purpose of pressure relief. This process effectively releases the excessive pressure in the inner tank 11 and protects the stability of the equipment and the production process.

[0032] And it can be achieved by Springs 1212 made of different materials will have different elastic moduli and yield strengths. Selecting a spring material with a higher elastic modulus or a larger yield strength can cause the spring to generate greater deformation resistance when subjected to the same pressure, thereby increasing the pressure relief threshold. On the contrary, selecting a spring material with a lower elastic modulus or a smaller yield strength will lower the pressure relief threshold.

[0033] As described above, it is only a preferred embodiment of the present invention, so the scope of implementation of the present invention cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the present invention patent and the content of the specification should still fall within the scope covered by the present invention.
