Description

Technical Field

[0001] The utility model relates to the field of styrene processing, in particular to a purification device for styrene processing. Background Art

[0002] Styrene is mainly produced in industry through alkylation reaction or cracking reaction. It is an important basic chemical raw material. Its polymers are widely used in furniture, packaging, electrical appliances, building materials and other fields, and have excellent physical properties and processing properties.

[0003] In the prior art, styrene needs to be purified during the processing. The purification is done by heating the unpurified styrene liquid, conveying the hot styrene vapor to the inside of the air compressor for compression, and then cooling the compressed gas to form styrene condensate liquid and discharge it. However, during the compression of styrene gas by the purification device, a compression space is reserved inside, so that after the condensed liquid is discharged, a small amount of residual condensate will still remain on the inner wall of the compression space, which cannot be quickly discharged, affecting the processing of the next batch of styrene purification, thereby reducing the processing efficiency. Utility Model Content

[0004] The utility model provides a styrene processing purification device to solve the problem that residual condensed beads still adhere to the inner wall of the compression space of the styrene processing purification device in the prior art and cannot be quickly discharged, thereby reducing the processing efficiency.

[0005] The technical solution adopted by the utility model is:

[0006] A purification device for styrene processing, comprising:

[0007] The compression chamber has a drain pipe connected to the bottom;

[0008] A heat exchange component, disposed at the outer wall of the compression bin, for cooling the compression bin;

[0009] A mobile compression assembly, disposed above the compression chamber, for compressing the gas in the compression chamber;

[0010] Wherein, the mobile compression component at least has:

[0011] A wiper seat, embedded in the compression chamber, with the outer wall of the wiper seat tightly fitting with the inner wall of the compression chamber;

[0012] The wiper seat can move up and down in the compression chamber to scrape off the condensed beads condensed on the inner wall of the compression chamber. When the wiper seat is in the lowest position, it contacts the bottom of the compression chamber.

[0013] Furthermore, the heat exchange component at least has:

[0014] Water tank;

[0015] The water inlet and outlet of the heat exchanger both penetrate the water tank and extend into the interior thereof, and a spiral condenser is connected between the water inlet and outlet of the heat exchanger.

[0016] Furthermore, the spiral condenser tube is spirally sleeved on the outside of the compression chamber.

[0017] Furthermore, the outer wall of the wiper seat is tightly fitted with the inner wall of the compression chamber through the first rubber sleeve.

[0018] Furthermore, the mobile compression component at least has:

[0019] A transmission plate which can move up and down has a second rubber sleeve on its bottom and is embedded on the top of the wiper seat through the second rubber sleeve.

[0020] Furthermore, the mobile compression component at least has:

[0021] The cylinder is connected to the transmission plate and is used for driving the wiper seat.

[0022] Furthermore, the cylinder passes through the top wall of the compression bin, and a sealing rubber ring is sleeved at the penetration point.

[0023] Furthermore, the mobile compression component also has:

[0024] A compression spring, one end of which is fixedly connected to the periphery of the top wall of the compression bin, and the other end of which is fixedly connected to the top of the wiper seat.

[0025] Furthermore, the bottom of the inner wall of the compression chamber is concave downward in the center, and the drain pipe is connected to the concave center of the bottom of the compression chamber; the wiper seat is convex downward in the center, and is interlocked with the bottom of the inner wall of the compression chamber.

[0026] The beneficial effects of the utility model are:

[0027] 1. The utility model provides a wiper seat movable to the bottom of the compression bin on the mobile compression assembly. After the valve on the drain pipe is opened, the wiper seat moves downward and cooperates with the surface rubber sleeve to scrape down the condensed water droplets on the inner wall of the compression bin, thereby improving the discharge efficiency of the condensed liquid after the pressurized condensation of styrene, improving the processing efficiency of styrene, and reducing the residual condensed liquid on the side wall of the purification device.

[0028] 2. The utility model has the bottom of the wiper seat interlocked with the bottom of the inner wall of the compression chamber. After the valve on the drain pipe is opened, the condensed liquid is squeezed out by relying on the interlocking of the bottom of the wiper seat and the bottom of the inner wall of the compression chamber, thereby improving the discharge efficiency of the condensed liquid at the bottom after the pressurized condensation of styrene, improving the processing efficiency of styrene, and reducing the residual condensed liquid at the bottom of the purification device.

[0029] 3. After the cylinder is closed, the compression spring is no longer subjected to the downward pulling force of the wiper seat, and the resilience of the compression spring can drive the wiper seat to move upward and reset, thereby reducing the reset weight at the output end of the cylinder and saving the reset force required after the cylinder is compressed and worked, thereby effectively saving the operating cost of the purification device.

[0042] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0043] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0044] See also Figure 1-4 This embodiment provides a purification device for styrene processing, which mainly includes a base 1, a mobile compression component 7, a compression chamber 8, a heat exchange component 9 and other parts.

[0045] like Figure 1 , Figure 2 As shown, the base 1 serves as a supporting structure, with supporting legs 2 fixedly connected on both sides of its top, a fixing plate 3 fixedly connected between the tops of the two supporting legs 2, connecting plates 4 fixedly connected on both sides of the top of the fixing plate 3, and then a mounting plate 5 fixedly connected between the tops of the two connecting plates 4.

[0046] like Figure 2 , Figure 3As shown, the heat exchange assembly 9 is fixedly connected to the top of the base 1. The heat exchange assembly 9 includes a water tank 92 and a heat exchanger 93. Two bearing plates 91 are fixedly connected to the bottom of the water tank 92, and are fixedly connected to the top of the base 1 through the two bearing plates 91. Among them, the bottom of the compression chamber 8 passes through the top of the water tank 92 and extends to the bottom of the water tank 92, and most of the compression chamber 8 is accommodated in the water tank 92. On the other hand, the heat exchanger 93 is fixedly connected to one side of the water tank 92, and the water inlet and outlet of the heat exchanger 93 both pass through the water tank 92 and extend to the inside of the water tank 92. A spiral condenser 94 is connected between the water inlet and outlet of the heat exchanger 93 and located outside the compression chamber 8. The heat exchanger 93 is usually composed of a tube bundle, a shell, a heat transfer surface, a heat transfer medium inlet and outlet, etc. The fluid can circulate between the tube bundle and the shell during the heat transfer process, and the heat is transferred to the fluid on the other side through the heat transfer surface. The water tank 92 is filled with condensate, and the heat exchanger 93 is started to continuously heat and cool the condensate inside the water tank 92 using the spiral condenser 94, and then the condensate inside the water tank 92 is continuously heat exchanged with the compression chamber 8, so that the compressed gas inside the compression chamber 8 can be cooled.

[0047] like Figure 2 , Figure 3 As shown, the compression chamber 8 is fixedly connected to the fixed plate 3 in a through-type manner. The bottom of the compression chamber 8 passes through the top of the heat exchange component 9 and extends to the bottom of the heat exchange component 9, and extends downward to connect to the drain pipe 11. The outside of the compression chamber 8 is connected to the air intake pipe 10. Among them, the drain pipe 11 is installed with a solenoid valve and a power control switch. One end of the air intake pipe 10 passes through the bottom of the fixed plate 3 and extends to the top of the fixed plate 3, and is connected to the external styrene gas delivery pipeline, which can deliver styrene gas to the inside of the compression chamber 8. The air intake pipe 10 is installed with a solenoid valve.

[0048] like Figure 3 , Figure 4As shown, the mobile compression assembly 7 is fixedly connected to the bottom of the mounting plate 5 through the cylinder 76, and the output end of the cylinder 76 passes through the top of the compression chamber 8 and extends to the inside of the compression chamber 8. The mobile compression assembly 7 also has a transmission plate 74. The transmission plate 74 is fixedly connected to the output end of the cylinder 76 and is located inside the compression chamber 8. The transmission plate 74 is embedded in the wiper seat 72 below. A first rubber sleeve 73 is sleeved between the outside and four sides of the wiper seat 72, and the wiper seat 72 is tightly fitted with the compression chamber 8 through the first rubber sleeve 73. Among them, the wiper seat 72 can move up and down under the control of the cylinder 76. When the cylinder 76 is working, the highest position of the wiper seat 72 is higher than the intake pipe 10 to prevent affecting the entry of gas; when the wiper seat 72 is at the lowest position, it contacts the bottom of the inner wall of the compression chamber 8. Therefore, when the wiper seat 72 moves downward, the water droplets condensed on the inner wall of the compression chamber 8 can be scraped down. At the same time, a second rubber sleeve 75 is sleeved on the bottom of the transmission plate 74 , and the transmission plate 74 is embedded in the top of the wiper seat 72 through the second rubber sleeve 75 , so as to reduce the wear between the transmission plate 74 and the wiper seat 72 .

[0049] Furthermore, if Figure 3 As shown, the bottom of the inner wall of the compression chamber 8 is concave in the center, and the drain pipe 11 is connected to the concave center of the bottom of the compression chamber 8; the bottom of the wiper seat 72 is convex in the center, and the bottom of the wiper seat 72 and the bottom of the inner wall of the compression chamber 8 are interlocked, and the condensed liquid is squeezed out by relying on the interlocking of the bottom of the wiper seat 72 and the bottom of the inner wall of the compression chamber 8.

[0050] In addition, if Figure 3 , Figure 4 As shown, the mobile compression assembly 7 of this embodiment also includes four compression springs 71, one end of the four compression springs 71 is respectively fixedly connected to the four sides of the top of the inner wall of the compression chamber 8, and the other end of the bottom of the four compression springs 71 is located inside the compression chamber 8 and is fixedly connected to the top of the wiper seat 72. The number of compression springs 71 provided in this embodiment is not limited to four, and can also be one, two, three, or more. The purpose of providing the compression spring 71 is that after the cylinder is closed, the compression spring is no longer subjected to the downward pulling force of the wiper seat, and the rebound force of the compression spring can drive the wiper seat to move up and reset, reducing the reset weight of the cylinder output end, saving the reset force required after the cylinder is compressed and worked, thereby effectively saving the operating cost of the purification device.

[0051] The following is the specific working process of the sewage treatment system of this embodiment:

[0052] First, a certain amount of air is reserved inside the compression chamber 8, and the valve on the air intake pipe 10 is opened to transport the styrene gas to the inside of the compression chamber 8 and below the mobile compression assembly 7. The cylinder 76 is started to push the transmission plate 74 to move downward, and the transmission plate 74 pushes the wiper seat 72 to move downward. When the wiper seat 72 moves downward, the four compression springs 71 are stretched, and when the wiper seat 72 moves downward, the styrene gas below is compressed, and the pressure of the styrene gas increases. At the same time, the heat exchanger 93 inside the heat exchange assembly 9 is started, and the condensate inside the water tank 92 is continuously cooled by continuous heat exchange of the fluid inside the spiral condenser tube 94. The condensate inside the water tank 92 is continuously cooled by continuous heat exchange of the compression chamber 8 and the pressure from above is matched, so that the compressed styrene gas can be condensed to form liquid styrene condensate beads. However, due to the reserved air at this time, when the wiper seat 72 moves to the lowest position, there is still a certain distance between it and the bottom of the compression chamber 8, and styrene condensate beads will be attached to the inner wall of this part of the compression chamber 8. When the condensation is completed, the valve on the drain pipe 11 is opened to discharge the styrene liquid and the reserved air, and the cylinder 76 continues to push the wiper seat 72 downward to scrape the styrene condensate beads on the inner wall of the compression chamber 8 downward. At the same time, due to the fit between the bottom of the wiper seat 72 and the bottom of the inner wall of the compression chamber 8, the scraped styrene condensate beads are squeezed out in a concentrated manner. Thereby, the discharge efficiency of the condensed liquid after the pressurized condensation of styrene is improved, the residual condensed liquid inside the purification device is reduced, and the processing efficiency of styrene is improved. After the processing is completed, the cylinder 76 is closed, and the compression spring 71 is no longer subjected to the downward pulling force of the wiper seat 72. The resilience of the compression spring 71 can drive the wiper seat 72 to move up and reset, reducing the reset weight of the output end of the cylinder 76, saving the reset force required after the cylinder 76 compresses and works, thereby effectively saving the operating cost of the purification device.

[0053] Preferably, the spiral condenser tube 94 is spirally sleeved on the outside of the compression chamber 8. Thus, the condensate around the outside of the compression chamber 8 in the water tank 92 can be cooled, and the cooling speed of the heat exchange component 9 can be increased, thereby improving the processing efficiency of the styrene processing purification device of this embodiment.

[0054] Preferably, a sealing rubber ring is provided at the connection between the cylinder 76 and the compression chamber 8, and the sealing rubber ring can improve the sealing performance of the connection between the cylinder 76 and the compression chamber 8.

[0055] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
