Example 1:

Please refer to Figure 1-7, a plastic masterbatch preparation and processing device, including a workbench 1, a screw conveyor pipe 2 is fixed horizontally on the top wall of the workbench 1, and an installation sleeve 3 is fixedly installed on the top wall of the workbench 1 1. The water tank 4 with the top opening and the cutting box 5 with the feed inlet on the side wall, the top wall of the installation sleeve 3 is vertically fixedly inserted with the material box 6, and the bottom of the material box 6 is fixedly installed with a tilting screw pipe extending to the screw conveyor. The heating pipe 7 in the 2, the horizontal rotation in the water tank 4 is equipped with a guide roller 8;

The side wall of the spiral conveying pipe 2 is uniformly and horizontally fixedly inserted with a heat transfer pipe 9 passing through the installation sleeve 3, and the inner wall of the installation sleeve 3 is fixedly installed with an electric atomizing nozzle 10 that cooperates with the heat transfer pipe 9;

A first support 11 is fixedly installed on the top wall of the workbench 1, and a ring sleeve 12 and a mounting rod 13 are inserted horizontally on the side wall of the first support 11, and the ring sleeve 12 is covered on the outside of the mounting rod 13. The fixed sleeve on the installation rod 13 is provided with an elastic sleeve 14, the outer wall of the elastic sleeve 14 is fixedly connected with the inner wall of the ring sleeve 12, and the top wall of the workbench 1 is fixedly installed with the first fixed connection between the power output end and the installation rod 13. The motor 15 and the elastic sleeve 14 are provided with a liquid supply mechanism that cooperates with the atomizing nozzle 10 .

The liquid supply mechanism includes a first cavity evenly opened on the elastic sleeve 14, a second cavity is opened on the installation rod 13, and a water inlet valve 16 and a drain valve 17 are fixedly installed on the side walls of each first cavity , and the water inlet valve 16 and the drain valve 17 communicate with the inside of the ring sleeve 12 and the second cavity respectively, and the bottom wall of the ring sleeve 12 is fixedly inserted with a water inlet pipe 18 extending into the water tank 4, and the first bracket 11 is fixedly inserted with a drain pipe 19 communicating with the second cavity, and the drain pipe 19 communicates with the atomizing nozzle 10, and the installation sleeve 3 is provided with a circulation mechanism that cooperates with the water tank 4.

The circulation mechanism comprises a first annular tube 20 with an open top fixed on the inner wall of the mounting sleeve 3 and a second annular tube 21 with an open top which is horizontally and fixedly sleeved on the heating tube 7, and the side wall of the first annular tube 20 is fixed A horizontal pipe 22 communicating with the second annular pipe 21 is inserted, and a return pipe 23 whose bottom end extends into the water tank 4 is fixedly inserted on the side wall of the first annular pipe 20 .

When it is necessary to produce plastic masterbatches, first pour the raw materials into the material box 6 and mix them evenly, then energize the heating pipe 7, open the solenoid valve at the bottom of the material box 6, and energize the atomizing nozzle 10. At this time, in the material box 6 The raw material slides along the heating tube 7 into the screw conveyor tube 2, during which the raw material in the heating tube 7 gradually becomes molten and flows into the screw conveyor tube 2, and during the working process of the screw conveyor tube 2, the screw conveyor The raw material in the molten state in the pipe 2 is extruded into the heat pipe 9, and then passes through the heat pipe 9, and then the staff uses a tool to pull the plastic strip passing through the heat pipe 9 below the liquid level in the water tank 4, and makes the plastic The strip passes under the guide roller 8 in the water tank 4, and then the plastic strip is pulled out from the water tank 4. The moment the plastic strip enters the liquid surface, the plastic strip is gradually cooled. When the plastic strip stretches out from the liquid surface, The plastic strip is in a completely cooled state, and then the cooled plastic strip passes through the gap between the elastic sleeve 14 and the first support 11. At this time, the elastic sleeve 14 is deformed and has a tendency to recover, and then the first motor 15 is started. When the first motor 15 drives the installation rod 13 to rotate, under the effect of friction, the elastic sleeve 14 that rotates with the installation rod 13 drives the plastic strip to move along the surface of the workbench 1, so that the plastic strip can automatically pass through the Material opening enters in the cutting box 5 and cuts.

In the initial state, the plastic strip is not in contact with the elastic member. At this time, the first cavity is filled with coolant, and the first cavity is filled from the space between the inner wall of the annular sleeve, the surface of the first bracket 11 and the side wall of the elastic sleeve 14. When the plastic strip enters the space between the elastic sleeve 14 and the top wall of the workbench 1, the elastic sleeve 14 is squeezed and deformed, and the first cavity near the plastic strip on the elastic sleeve 14 is Squeeze, under the action of the water inlet valve 16 and the drain valve 17, the coolant in the first cavity enters the second cavity and enters the atomizing nozzle 10 along the drain pipe 19, so that it can be atomized The spray head 10 supplies liquid, and then the atomizing spray head 10 sprays the cooling liquid. At this time, the cooling liquid is atomized into small droplets and sprayed on the surface of the heat conduction pipe 9. Under the effect of heat exchange, the small liquid droplets absorb the heat of the heat conduction pipe 9. Evaporation forms water vapor to flow upward. When the steam is attached to the outer wall of the material box 6, under the effect of heat exchange: the material box 6 absorbs the heat of the steam, and the raw material absorbs the heat of the material box 6. At this time, the raw material in the material box 6 The temperature rises, so that the steam on the outer wall of the material box 6 can be liquefied into small water droplets. After the steam is liquefied into small water droplets, the small water droplets flow down along the outer wall of the material box 6 and the inner wall of the installation sleeve 3, and finally flow to the first In the first annular pipe 20 and the second annular pipe 21, and the cryogenic liquid in the second annular pipe 21 flows into the first annular pipe 20 along the horizontal pipe 22, and the liquid in the first annular pipe 20 finally flows along the return pipe 23 Flow into the water tank 4, so that the coolant in the water tank 4 can be cooled during the working process, the frequency of changing the coolant is reduced, and the work efficiency is improved; The water mist absorbs the heat of the heat pipe 9 and can initially cool down the plastic strip, reducing the heat absorbed by the cooling liquid in the water tank 4; heating the raw material through steam reduces the time required for the heating pipe 7 to heat the raw material to melting, thereby reducing the temperature of the plastic strip. To improve work efficiency.

Since both the first annular pipe 20 and the second annular pipe 21 are open at the top, when the steam flows upwards, the condensate in the first annular pipe 20 and the second annular pipe 21 cannot absorb the heat of the steam, which ensures that the return pipe What is discharged in 23 is the effect of cryogenic liquid.

Because the first motor 15 continues to drive the installation rod 13 to rotate, the squeezed first cavity quickly moves away from the installation rod 13. At this time, the first cavity recovers. Under the action of the water inlet valve 16 and the drain valve 17, the The first cavity absorbs coolant from the space between the inner wall of the annular sleeve, the surface of the first bracket 11 and the side wall of the elastic sleeve 14. At this time, the space is in a negative pressure state, so this space absorbs from the water tank 4 through the water inlet pipe 18 Cooling liquid, so that the cooling liquid can be replenished in the first cavity in time, which plays a role in ensuring that the atomizing nozzle 10 can work normally.

Specifically, as shown in Figure 2, the guide roller 8 includes a mounting frame 801 and a mounting tube 802, and the mounting tube 802 is horizontally rotated and inserted between the two mounting frames 801, and the side wall of the mounting tube 802 is provided with the inside of the mounting tube 802. The first through hole communicated with the second through hole communicated with the installation pipe 802 is opened on the side wall of the installation frame 801 , and the water inlet pipe 18 extends into the second through hole.

During the working process, the plastic strip is in contact with the outer wall of the installation pipe 802. By opening the first through hole on the outer wall of the installation pipe 802, the contact area between the plastic strip and the installation pipe 802 is reduced, that is, the contact area between the plastic strip and the cooling liquid is increased. The contact area has played a role in improving the cooling effect; since the water inlet pipe 18 communicates with the second through hole, the water inlet pipe 18 absorbs water from the water tank 4 through the second through hole, the installation pipe 802, and the first through hole, thereby being able to guide the The coolant with a higher temperature around the roller 8 is absorbed, which plays the role of the auxiliary return pipe 23 in reducing the temperature of the coolant in the water tank 4 .

Concrete, as shown in Figure 1 and Figure 2, the interior horizontal rotation of cutting box 5 is equipped with rotating rod 24, and blade 25 is evenly fixedly installed on rotating rod 24, and the outer wall of cutting box 5 is fixedly installed with power output end and rotating shaft. The rod 24 is fixedly connected to the second motor 26, and the top wall of the workbench 1 is vertically provided with a discharge port whose bottom end extends to the bottom wall of the workbench 1;

An air outlet is provided on the side wall of the cutting box 5 near the side of the installation sleeve 3 , and a fan blade 27 is fixedly installed on the rotating rod 24 .

Start the second motor 26 during the working process, and now the second motor 26 drives the rotating rod 24 to rotate, and the rotating rod 24 drives the blade 25 to rotate; The cooled plastic strip automatically enters the cutting box 5 through the feeding port. When the plastic strip enters the cutting box 5 and contacts the high-speed rotating blade 25, the blade 25 cuts the plastic strip, and then the plastic particles pass through the discharge port. Sliding to the outside world, thus realizing the production of masterbatch.

During the working process of the rotating rod 24, the rotating rod 24 drives the fan blade 27 to rotate. At this time, the gas in the material box 6 is discharged to the outside through the exhaust port, and then the cutting box 5 sucks air from the bottom wall of the workbench 1 through the discharge port; Therefore, the low-temperature gas located at the bottom wall of the workbench 1 can be discharged to the top wall of the workbench 1 through the exhaust port during the operation of the fan blade 27. Since the exhaust port is located at the side of the cutting box 5 near the installation sleeve 3, The airflow discharged from the exhaust port can blow away the high-temperature gas around the water tank 4, thereby reducing the temperature around the water tank 4. At this time, the surrounding of the water tank 4 is filled with low-temperature gas, so that the water tank can be absorbed by the low-temperature gas under the action of heat exchange. 4 The heat of the coolant plays an auxiliary role in reducing the temperature of the coolant.

Specifically, as shown in Figure 1, the side wall of the installation sleeve 3 is evenly inclined and fixedly inserted with a gas pipe 28 whose top end extends to the inner wall of the material box 6, and the inner wall of the material box 6 is fixedly installed with a filter screen that cooperates with the air pipe 28 41.

The horizontal fixed sleeve on the outer wall of the installation sleeve 3 is provided with a guide tube 29 , and the bottom wall of the guide tube 29 near the water tank 4 side is provided with an air inlet, and the guide tube 29 communicates with the air pipe 28 .

During the rainy season in the south, the air is humid, so the moisture content on the surface of the raw material is relatively large. When the raw material is melted, the moisture turns into water vapor, resulting in bubbles in the molten plastic strip, so that the quality of the produced masterbatch is unqualified. Therefore raw material needs to be dried; During fan blade 27 rotation process, the air flow that discharges in cutting box 5 impacts the high-temperature gas around water tank 4, and this moment, high-temperature gas has the tendency that moves along the direction of air-flow impact force, so high-temperature gas will Impact the outer wall of the installation sleeve 3. When the high-temperature gas contacts the outer wall of the installation sleeve 3, the direction of the airflow changes. At this time, the gas diffuses along the outer wall of the installation sleeve 3 to the surroundings, and the gas that flows upward enters the guide tube 29 that is open at the bottom. Then flow along the guide tube 29, and part of the high-temperature gas in the guide tube 29 enters the air pipe 28, and the air flow passes through the air pipe 28 and enters the material box 6; when the cooling liquid vapor in the installation sleeve 3 goes upward When flowing, the steam contacts the air pipe 28, and under the effect of heat exchange, the temperature of the air in the air pipe 28 rises again, so what enters the material box 6 is high-temperature gas, and when the hot air flow enters the material box 6, the hot air flow flows upwards , at this time, the hot air flow can evenly heat the raw materials in the material box 6, which plays a role in improving the preheating effect; at the same time, under the action of the hot air flow, the water vapor on the surface of the raw material can be evaporated, and the water vapor on the surface of the raw material can be evaporated under the impact force of the air flow. The water vapor is discharged from the feed box 6, which plays a role in drying the raw materials.

And under the effect of the filter screen 41, raw materials can be prevented from entering the air pipe 28, which plays a role in preventing the air pipe 28 from being blocked.

Specifically, as shown in Fig. 1, Fig. 2 and Fig. 4, springs 30 are fixed vertically and symmetrically on the bottom wall of the water tank 4, and the tops of the plurality of springs 30 are fixedly mounted together with an aeration plate 31 whose output end is upward.

A sleeve 32 is fixed horizontally on the inner side wall of the water tank 4, an elastic film 33 is fixedly installed on the side wall of the sleeve 32 near the side of the guide roller 8, and an air inlet valve is fixedly installed on the top wall and the bottom wall of the sleeve 32 respectively. 34 and an exhaust valve 35, the intake valve 34 is fixedly installed with a first conduit 36 extending into the material box 6, and the exhaust valve 35 is fixedly installed with a second conduit 37 communicating with the aeration plate 31.

The end of the installation tube 802 away from the mounting frame 801 is horizontally fixed with a reciprocating screw rod 38 , on which a slider 39 is threaded, and a plurality of linkage rods 40 are fixedly installed between the slider 39 and the elastic membrane 33 .

During the rotation of the fan blade 27, a large amount of low-temperature gas is contained in the material box 6; when the connecting rod 40 pulls the plastic strip through the elastic sleeve 14 to move, under the action of friction, the plastic strip drives the installation pipe 802 to rotate, and the installation pipe 802 is installed at this time. The tube 802 drives the reciprocating screw rod 38 to rotate, so that the slider 39 reciprocates along the reciprocating screw rod 38. When the slider 39 moves away from the sleeve 32, the slider 39 pulls the elastic film 33 through the linkage rod 40. At this time, the elastic The volume of the space between the film 33 and the sleeve 32 increases, so the sleeve 32 absorbs low-temperature gas from the material box 6 through the inlet valve 34 and the first conduit 36; when the slider 39 moves toward the direction close to the sleeve 32 At this time, the elastic membrane 33 recovers under the action of the linkage rod 40. At this time, the gas in the sleeve 32 is squeezed, and the low-temperature gas in the sleeve 32 passes through the exhaust valve 35 and enters the exposure chamber along the second conduit 37. In the air plate 31, at this time, the aeration plate 31 is subjected to upward buoyancy force, so the aeration plate 31 floats up and pulls the spring 30. It can absorb the heat of the cooling liquid in the water tank 4 and play a role in cooling the cooling liquid; when the slider 39 moves away from the sleeve 32 again, the sleeve 32 stops supplying air to the aeration plate 31, and at this time the buoyancy of the aeration plate 31 decrease, so the stretched spring 30 begins to recover and pulls the aeration plate 31 to move down. During the downward movement of the aeration plate 31, the aeration plate 31 drives the coolant in the water tank 4 to shake, so that the temperature of the coolant can be uniform , thereby being able to contact the coolant with a lower temperature at the bottom of the water tank 4 with the plastic strip, thereby improving the utilization rate of the coolant.

Working principle: When it is necessary to produce plastic masterbatches, first pour the raw materials into the material box 6 and mix them evenly, then turn on the heating pipe 7, open the solenoid valve at the bottom of the material box 6, and turn on the atomizing nozzle 10. At this time, the material The raw material in the box 6 slides along the heating tube 7 into the screw conveyor tube 2, during which the raw material in the heating tube 7 gradually becomes molten and flows into the screw tube 2, during the working process of the screw tube 2 , the raw material in the molten state in the screw conveyor pipe 2 is extruded into the heat pipe 9, and then passes through the heat pipe 9, and then the staff uses a tool to pull the plastic strip passing through the heat pipe 9 to the liquid level in the water tank 4, And make the plastic strip pass below the guide roller 8 in the water tank 4, then the plastic strip is pulled out from the water tank 4, the moment the plastic strip enters the liquid surface, the plastic strip cools gradually, when the plastic strip stretches out from the liquid surface When going out, the plastic strip is in a completely cooled state, then pass the cooled plastic strip through the gap between the elastic sleeve 14 and the first bracket 11, at this time the elastic sleeve 14 is deformed and has a tendency to recover, and then the first motor is started 15. At this time, the first motor 15 drives the installation rod 13 to rotate. Under the action of friction, the elastic sleeve 14 that rotates with the installation rod 13 drives the plastic strip to move along the surface of the workbench 1, so that the plastic strip can automatically Enter into cutting box 5 through feed inlet and cut.

In the initial state, the plastic strip is not in contact with the elastic member. At this time, the first cavity is filled with coolant, and the first cavity is filled from the space between the inner wall of the annular sleeve, the surface of the first bracket 11 and the side wall of the elastic sleeve 14. When the plastic strip enters the space between the elastic sleeve 14 and the top wall of the workbench 1, the elastic sleeve 14 is squeezed and deformed, and the first cavity near the plastic strip on the elastic sleeve 14 is Squeeze, under the action of the water inlet valve 16 and the drain valve 17, the coolant in the first cavity enters the second cavity and enters the atomizing nozzle 10 along the drain pipe 19, so that it can be atomized The spray head 10 supplies liquid, and then the atomizing spray head 10 sprays the cooling liquid. At this time, the cooling liquid is atomized into small droplets and sprayed on the surface of the heat conduction pipe 9. Under the effect of heat exchange, the small liquid droplets absorb the heat of the heat conduction pipe 9. Evaporation forms water vapor to flow upward. When the steam is attached to the outer wall of the material box 6, under the effect of heat exchange: the material box 6 absorbs the heat of the steam, and the raw material absorbs the heat of the material box 6. At this time, the raw material in the material box 6 The temperature rises, so that the steam on the outer wall of the material box 6 can be liquefied into small water droplets. After the steam is liquefied into small water droplets, the small water droplets flow down along the outer wall of the material box 6 and the inner wall of the installation sleeve 3, and finally flow to the first In the first annular pipe 20 and the second annular pipe 21, and the cryogenic liquid in the second annular pipe 21 flows into the first annular pipe 20 along the horizontal pipe 22, and the liquid in the first annular pipe 20 finally flows along the return pipe 23 Flow into the water tank 4, so that the coolant in the water tank 4 can be cooled during the working process, the frequency of changing the coolant is reduced, and the work efficiency is improved; The water mist absorbs the heat of the heat pipe 9 and can initially cool down the plastic strip, reducing the heat absorbed by the cooling liquid in the water tank 4; heating the raw material through steam reduces the time required for the heating pipe 7 to heat the raw material to melting, thereby reducing the temperature of the plastic strip. To improve work efficiency.

Since both the first annular pipe 20 and the second annular pipe 21 are open at the top, when the steam flows upwards, the condensate in the first annular pipe 20 and the second annular pipe 21 cannot absorb the heat of the steam, which ensures that the return pipe What is discharged in 23 is the effect of cryogenic liquid.

Because the first motor 15 continues to drive the installation rod 13 to rotate, the squeezed first cavity quickly moves away from the installation rod 13. At this time, the first cavity recovers. Under the action of the water inlet valve 16 and the drain valve 17, the The first cavity absorbs coolant from the space between the inner wall of the annular sleeve, the surface of the first bracket 11 and the side wall of the elastic sleeve 14. At this time, the space is in a negative pressure state, so this space absorbs from the water tank 4 through the water inlet pipe 18 Cooling liquid, so that the cooling liquid can be replenished in the first cavity in time, which plays a role in ensuring that the atomizing nozzle 10 can work normally.

During the working process, the plastic strip is in contact with the outer wall of the installation pipe 802. By opening the first through hole on the outer wall of the installation pipe 802, the contact area between the plastic strip and the installation pipe 802 is reduced, that is, the contact area between the plastic strip and the cooling liquid is increased. The contact area has played a role in improving the cooling effect; since the water inlet pipe 18 communicates with the second through hole, the water inlet pipe 18 absorbs water from the water tank 4 through the second through hole, the installation pipe 802, and the first through hole, thereby being able to guide the The coolant with a higher temperature around the roller 8 is absorbed, which plays the role of the auxiliary return pipe 23 in reducing the temperature of the coolant in the water tank 4 .

Start the second motor 26 during the working process, and now the second motor 26 drives the rotating rod 24 to rotate, and the rotating rod 24 drives the blade 25 to rotate; The cooled plastic strip automatically enters the cutting box 5 through the feeding port. When the plastic strip enters the cutting box 5 and contacts the high-speed rotating blade 25, the blade 25 cuts the plastic strip, and then the plastic particles pass through the discharge port. Sliding to the outside world, thus realizing the production of masterbatch.

During the working process of the rotating rod 24, the rotating rod 24 drives the fan blade 27 to rotate. At this time, the gas in the material box 6 is discharged to the outside through the exhaust port, and then the cutting box 5 sucks air from the bottom wall of the workbench 1 through the discharge port; Therefore, the low-temperature gas located at the bottom wall of the workbench 1 can be discharged to the top wall of the workbench 1 through the exhaust port during the operation of the fan blade 27. Since the exhaust port is located at the side of the cutting box 5 near the installation sleeve 3, The airflow discharged from the exhaust port can blow away the high-temperature gas around the water tank 4, thereby reducing the temperature around the water tank 4. At this time, the surrounding of the water tank 4 is filled with low-temperature gas, so that the water tank can be absorbed by the low-temperature gas under the action of heat exchange. 4 The heat of the coolant plays an auxiliary role in reducing the temperature of the coolant.

During the rainy season in the south, the air is humid, so the moisture content on the surface of the raw material is relatively large. When the raw material is melted, the moisture turns into water vapor, resulting in bubbles in the molten plastic strip, so that the quality of the produced masterbatch is unqualified. Therefore raw material needs to be dried; During fan blade 27 rotation process, the air flow that discharges in cutting box 5 impacts the high-temperature gas around water tank 4, and this moment, high-temperature gas has the tendency that moves along the direction of air-flow impact force, so high-temperature gas will Impact the outer wall of the installation sleeve 3. When the high-temperature gas contacts the outer wall of the installation sleeve 3, the direction of the airflow changes. At this time, the gas diffuses along the outer wall of the installation sleeve 3 to the surroundings, and the gas that flows upward enters the guide tube 29 that is open at the bottom. Then flow along the guide tube 29, and part of the high-temperature gas in the guide tube 29 enters the air pipe 28, and the air flow passes through the air pipe 28 and enters the material box 6; when the cooling liquid vapor in the installation sleeve 3 goes upward When flowing, the steam contacts the air pipe 28, and under the effect of heat exchange, the temperature of the air in the air pipe 28 rises again, so what enters the material box 6 is high-temperature gas, and when the hot air flow enters the material box 6, the hot air flow flows upwards , at this time, the hot air flow can evenly heat the raw materials in the material box 6, which plays a role in improving the preheating effect; at the same time, under the action of the hot air flow, the water vapor on the surface of the raw material can be evaporated, and the water vapor on the surface of the raw material can be evaporated under the impact force of the air flow. The water vapor is discharged from the feed box 6, which plays a role in drying the raw materials.

And under the effect of the filter screen 41, raw materials can be prevented from entering the air pipe 28, which plays a role in preventing the air pipe 28 from being blocked.

During the rotation of the fan blade 27, a large amount of low-temperature gas is contained in the material box 6; when the connecting rod 40 pulls the plastic strip through the elastic sleeve 14 to move, under the action of friction, the plastic strip drives the installation pipe 802 to rotate, and the installation pipe 802 is installed at this time. The tube 802 drives the reciprocating screw rod 38 to rotate, so that the slider 39 reciprocates along the reciprocating screw rod 38. When the slider 39 moves away from the sleeve 32, the slider 39 pulls the elastic film 33 through the linkage rod 40. At this time, the elastic The volume of the space between the film 33 and the sleeve 32 increases, so the sleeve 32 absorbs low-temperature gas from the material box 6 through the inlet valve 34 and the first conduit 36; when the slider 39 moves toward the direction close to the sleeve 32 At this time, the elastic membrane 33 recovers under the action of the linkage rod 40. At this time, the gas in the sleeve 32 is squeezed, and the low-temperature gas in the sleeve 32 passes through the exhaust valve 35 and enters the exposure chamber along the second conduit 37. In the air plate 31, at this time, the aeration plate 31 is subjected to upward buoyancy force, so the aeration plate 31 floats up and pulls the spring 30. It can absorb the heat of the cooling liquid in the water tank 4 and play a role in cooling the cooling liquid; when the slider 39 moves away from the sleeve 32 again, the sleeve 32 stops supplying air to the aeration plate 31, and at this time the buoyancy of the aeration plate 31 decrease, so the stretched spring 30 begins to recover and pulls the aeration plate 31 to move down. During the downward movement of the aeration plate 31, the aeration plate 31 drives the coolant in the water tank 4 to shake, so that the temperature of the coolant can be uniform , thereby being able to contact the coolant with a lower temperature at the bottom of the water tank 4 with the plastic strip, thereby improving the utilization rate of the coolant.
