Description

Technical Field

[0001] The present invention relates to the technical field of KL540 synthesis equipment, and in particular to a low-wastewater KL540 synthesis device and method. Background Art

[0002] KL540 refers to polyester polyurethane. Polyester polyurethane is a thermoplastic elastomer made from polyester polyols and isocyanates through a polymerization reaction. Polyester polyurethane has excellent physical, chemical, and mechanical properties, such as high tensile strength, abrasion resistance, chemical resistance, good weather resistance, oil and grease resistance, excellent elasticity, and can be processed into various shapes. It is widely used in the manufacture of rubber products, plastics, coatings, adhesives, foam materials, textiles, electrical insulation materials, and cement reinforcement.

[0003] The common steps for synthesizing polyester polyurethane are as follows: 1. Preparation of polyester polyol. 2. Synthesis of polyester polyurethane: Prefabricate isocyanate resin prepolymer and polyester polyol, then mix the two substances under controlled reaction conditions, add a catalyst and coating additives, and react to form polyester polyurethane. During the synthesis of polyester polyurethane, contaminants will remain on the surface of the polyester polyurethane. Therefore, after the polyester polyurethane is processed, the polyester polyurethane product needs to be rinsed to remove surface contaminants.

[0004] Currently, when flushing polyester polyurethane, the top of the polyester polyurethane is sprayed, and the cleaning liquid flushes the polyester polyurethane from top to bottom, resulting in poor flushing effect on the polyester polyurethane located below, which requires an increase in the amount of cleaning liquid used and increases the generation of wastewater;

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0039] Example 1

[0040] In order to solve the technical problems in the background technology, the following low-wastewater KL540 synthesis device and method are provided:

[0041] Combine Figures 1-9As shown, the low-wastewater KL540 synthesis device and method provided by the present invention include a treatment box 1, the top of which is open, and electric push rods 11 are symmetrically fixedly installed on the outer wall of the treatment box 1. The piston rods of the two electric push rods 11 are fixedly connected to a cover plate 12 that can seal the open end of the treatment box 1. A filter plate 13 is fixedly installed in the treatment box 1, and the interior of the treatment box 1 is divided into an upper cavity 14 and a lower cavity 15 by the filter plate 13. A discharge valve 16 and a drain valve 17 that are respectively connected to the upper cavity 14 and the lower cavity 15 are fixedly installed on the treatment box 1; a stirring shaft 2 in a vertical direction is rotatably installed on the cover plate 12 and located in the upper cavity 14, and a plurality of stirring rods 21 are symmetrically installed on the outside of the stirring shaft 2, and the plurality of stirring rods 21 are linearly arranged along the axis direction of the stirring shaft 2. The arrangement is arranged in an array. A driving member 22 acting on the stirring shaft 2 is installed on the cover plate 12, which is used to rotate the stirring shaft 2 on the cover plate 12. A spray assembly 3 connected to multiple stirring rods 21 is installed on the stirring shaft 2. One end of the spray assembly 3 extends to the outside of the cover plate 12, and the other end is connected to multiple stirring rods 21. The spray assembly 3 is used to spray cleaning liquid into the upper cavity 14. The processing box 1 is provided with a liquid pumping assembly 4 connected to the interior of the lower cavity 15, and the other end of the liquid pumping assembly 4 is connected to the spray assembly 3. The waste liquid in the lower cavity 15 is connected to the spray assembly 3 through the liquid pumping assembly 4. The supporting frame 7 is also included. The processing box 1 is hinged to the supporting frame 7 through a hinge shaft, and a motor 71 connected to the hinge shaft is fixedly mounted on the supporting frame 7.

[0042] When the polyester polyurethane is processed and flushed, the polyester polyurethane is fed into the processing box 1 through the notch, and the cleaning liquid is delivered to the liquid inlet pipe 32 by the cleaning liquid delivery pump. The cleaning liquid is sprayed out through the liquid port 212, and the polyester polyurethane is sprayed with the cleaning liquid for flushing. The motor 221 and the electric push rod 11 cooperate to make the multiple stirring rods 21 rotate around the stirring shaft 2 and move up and down at the same time, so as to fully clean the inside of the polyester polyurethane, instead of spraying the cleaning liquid on the top of the polyester polyurethane, the cleaning liquid is flushed from top to bottom, which improves The flushing effect on polyester polyurethane is improved, thereby reducing the usage of cleaning fluid and reducing the generation of waste water; through the design of the liquid pumping component 4, the waste liquid generated by flushing polyester polyurethane falls into the lower cavity 15, and the liquid pump 41 is controlled to be turned on. The liquid pump 41 extracts the waste liquid in the lower cavity 15 and transports it to the liquid storage tank 31 through the corrugated hose 43, so that the waste liquid is mixed with the cleaning fluid and then transported to the cavity 211 to flush the polyester polyurethane, so that the cleaning fluid after flushing the polyester polyurethane can be reused, thereby reducing the usage of cleaning fluid and further reducing the generation of waste water.

[0043] Through the design of the supporting frame 7 and the motor 71, after the polyester polyurethane is flushed, when the waste liquid and polyester polyurethane in the treatment box 1 are discharged, the motor 71 rotates the treatment box 1 on the supporting frame 7, so that the discharge valve 16 and the liquid discharge valve 17 are tilted downward in the direction away from the treatment box 1, so that the waste water and polyester polyurethane in the treatment box 1 are discharged more thoroughly.

[0044] Example 2

[0045] like Figures 1-9 As shown, based on the above embodiment, this embodiment further provides the following content:

[0046] In this embodiment, the driving member 22 includes a motor 221 fixedly mounted on the cover plate 12 , and the output shaft of the motor 221 is connected to the stirring shaft 2 via a bevel gear assembly 222 .

[0047] When in use, the motor 221 is controlled to be turned on, and the output shaft of the motor 221 rotates to drive the stirring shaft 2 to rotate through the bevel gear assembly 222, which is easy to operate.

[0048] In this embodiment, the spray assembly 3 includes a liquid storage tank 31 fixedly mounted on the top of the cover plate 12, a liquid inlet pipe 32 fixedly mounted on one side of the top of the liquid storage tank 31, a liquid pump 33 mounted on the bottom of the liquid storage tank 31, and a connecting pipe mounted on the liquid outlet end of the liquid pump 33; a accommodating chamber 23 is constructed in the stirring shaft 2, a liquid passage pipe 34 is fixed on the stirring shaft 2 and located in the accommodating chamber 23, and the liquid passage pipe 34 and the connecting pipe are connected by a rotating joint 35; a cavity 211 is constructed inside the stirring rod 21, and a liquid passage port 212 connected to the interior of the cavity 211 is opened on both sides of the stirring rod 21, a one-way valve 214 connected to the liquid passage port 212 is fixedly mounted in the cavity 211, and the liquid passage pipe 34 and the cavity 211 are connected through a connecting pipe 213.

[0049] When in use, the liquid inlet pipe 32 is connected to the cleaning liquid delivery pump, and the cleaning liquid delivery pump delivers the cleaning liquid into the liquid storage tank 31. The liquid extraction pump 33 is controlled to extract the cleaning liquid in the liquid storage tank 31 and deliver it to the cavity 211 through the liquid pipe 34. The cleaning liquid pushes the one-way valve 214 to open, and is thus sprayed out through the liquid opening 212. The design of the one-way valve 214 realizes one-way flow from the cavity 211 to the liquid opening 212, preventing the polyester polyurethane from flowing into the cavity 211 through the liquid opening 212. After the polyester polyurethane is flushed and the wastewater and polyester polyurethane are discharged, the liquid inlet pipe 32 is connected to the water pump, and water is transported into the liquid inlet pipe 32 by the water pump, and sprayed out through the liquid port 212. Through the cooperation of the electric push rod 11 and the motor 221, the multiple stirring rods 21 rotate around the stirring shaft 2 and move up and down at the same time, so as to flush the inner wall of the treatment box 1; the design of the rotating joint 35 is that when the stirring shaft 2 rotates, it drives the liquid pipe 34 to rotate, and the rotating joint 35 itself rotates without affecting the normal use of the equipment.

[0050] In this embodiment, the liquid pumping component 4 includes a liquid pump 41 fixedly installed on the outside of the processing box 1. The liquid inlet end of the liquid pump 41 is connected to the lower cavity 15 through a connecting hose 42, and the liquid outlet end of the liquid pump 41 is connected to the other side of the top of the liquid storage tank 31 through a corrugated hose 43.

[0051] During use, the waste liquid generated by flushing the polyester polyurethane falls into the lower cavity 15, and the liquid pump 41 is controlled to open. The liquid pump 41 extracts the waste liquid in the lower cavity 15 and transports it to the liquid storage tank 31 through the corrugated hose 43. The waste liquid is mixed with the cleaning liquid and then transported to the cavity 211 to flush the polyester polyurethane, so that the cleaning liquid after flushing the polyester polyurethane can be reused, thereby reducing the use of cleaning liquid and further reducing the generation of wastewater; the design of the corrugated hose 43 does not affect the lifting and lowering of the cover plate 12.

[0052] Example 3

[0053] like Figures 1-9 As shown, based on the above embodiment, this embodiment further provides the following content:

[0054] In this embodiment, an adsorption mechanism 5 connected to the lower cavity 15 is installed on one side of the processing box 1, and the end of the connecting hose 42 away from the liquid pump 41 is connected to the adsorption mechanism 5. The adsorption mechanism 5 is used to adsorb and filter harmful substances such as polyester polyurethane particles in the waste liquid.

[0055] Through the design of the adsorption mechanism 5, the adsorption mechanism 5 adsorbs and filters harmful substances such as polyester polyurethane particles generated when flushing polyester polyurethane in the waste liquid, effectively avoiding cross contamination when the waste liquid and the cleaning liquid are mixed, thereby improving the flushing effect of the waste liquid and the mixed liquid on the polyester polyurethane, further reducing the use of the cleaning liquid, and further reducing the generation of wastewater.

[0056] In this embodiment, the adsorption mechanism 5 includes a filter shell 51 fixedly mounted on the side wall of the treatment box 1. The filter shell 51 is open on the side away from the treatment box 1. A sealing plate 52 for sealing the open end thereof is hinged on the filter shell 51. The sealing plate 52 and the filter shell 51 are fixed by a buckle. A sealing ring 53 is installed on the side wall of the sealing plate 52. When the sealing plate 52 blocks the open end of the filter shell 51, the sealing ring 53 forms a conflict with the filter shell 51; the top and bottom of the filter shell 51 are both provided with through holes 54 connected to the interior thereof, one of the through holes 54 is connected to the lower cavity 15 through a straight pipe, and the other through hole 54 is connected to the connecting hose 42. A filter screen 55 for sealing the through hole 54 is fixed in the filter shell 51, and the filter shell 51 is filled with activated carbon particles.

[0057] After the waste liquid generated by flushing the polyester polyurethane falls into the lower cavity 15, it flows into the filter housing 51 through a straight pipe and is connected to the liquid pump 41 through the connecting hose 42. When the liquid pump 41 is turned on, the waste liquid in the lower cavity 15 can be extracted and transported to the liquid storage tank 31 through the corrugated hose 43. When the waste liquid flows through the filter housing 51 to the connecting hose 42, the activated carbon particles come into contact with the waste liquid, thereby adsorbing and filtering harmful substances such as polyester polyurethane particles in the waste liquid; the design of the two filter screens 55 realizes the blocking of the two through holes 54, preventing the activated carbon particles from entering the through holes 54 and blocking the through holes 54; when the activated carbon particles are replaced, the fixing of the sealing plate 52 and the filter housing 51 by the buckle can be cancelled, and the blocking of the opening of the filter housing 51 by the sealing plate 52 can be cancelled. At this time, the activated carbon particles can be discharged through the open end of the filter housing 51 for replacement; the design of the sealing ring 53 increases the sealing between the sealing plate 52 and the filter housing 51, thereby improving the blocking effect of the opening of the filter housing 51.

[0058] Example 4

[0059] like Figures 1-9 As shown, based on the above embodiment, this embodiment further provides the following content:

[0060] In this embodiment, a mixing element 6 for mixing cleaning liquid and waste liquid is installed in the liquid storage tank 31; the mixing element 6 includes a rotating rod 61 that is horizontally and rotatably installed in the liquid storage tank 31, and a plurality of connecting rod groups are fixedly installed outside the rotating rod 61 and along its axial direction, and each connecting rod group includes a plurality of connecting rods 62 arranged in a ring array outside the rotating rod 61.

[0061] By utilizing the design of the rotating rod 61 and the connecting rod 62, the rotating rod 61 can be rotated in the liquid storage tank 31, which can drive multiple connecting rods 62 to rotate around the rotating rod 61, thereby stirring and mixing the cleaning liquid and waste liquid in the liquid storage tank 31, improving the mixing effect of the cleaning liquid and waste liquid, improving the flushing effect of the polyester polyurethane, and further reducing the generation of wastewater.

[0062] In this embodiment, an annular fixing plate 63 is fixed to the outside of the multiple connecting rods 62, and the outer wall of the annular fixing plate 63 is constructed with inclined holes 631 in a circular array. The inclined holes 631 located below the connection between the liquid storage tank 31 and the corrugated hose 43 are open upward, and there is a gap between the two ends of the annular fixing plate 63 and the inner wall of the liquid storage tank 31.

[0063] By utilizing the design of the annular fixing plate 63 and the inclined hole 631, when the waste liquid flows into the liquid storage tank 31 through the corrugated hose 43, it flows into the inclined hole 631 located below the corrugated hose 43, and the waste liquid flows into the inclined hole 631 and is stored. As a result, under the action of the gravity of the waste liquid, the annular fixing plate 63 rotates around the rotating rod 61, and the rotating rod 61 rotates in the liquid storage tank 31. When the annular fixing plate 63 rotates, the inclined hole 631 storing the waste liquid opens downward, and the waste liquid can flow into the liquid storage tank 31. and, when the annular fixing plate 63 rotates, the rotating rod 61 rotates in the liquid storage tank 31, so that there is no need to apply additional power to the rotating rod 61, thereby reducing the energy consumption of the equipment; in addition, when the annular fixing plate 63 rotates around the rotating rod 61, the annular fixing plate 63 contacts the mixture of the waste liquid and the cleaning liquid, thereby pushing the mixed liquid to flow to the outside of the annular fixing plate 63 and contact the inner wall of the liquid storage tank 31 and then flow in the opposite direction, further improving the mixing effect of the waste liquid and the cleaning liquid.

[0064] The operating method of the low-wastewater KL540 synthesis device includes the following steps:

[0065] Step 1: When the polyester polyurethane is processed and rinsed, the cover plate 12 is moved away from the processing box 1 by the electric push rod 11, and a gap is formed between the cover plate 12 and the top of the processing box 1. The polyester polyurethane is fed into the processing box 1 through the gap. The polyester polyurethane is located in the upper cavity 14. The cleaning liquid is delivered to the liquid inlet pipe 32 by the cleaning liquid delivery pump. The cleaning liquid enters the liquid storage tank 31. The liquid extraction pump 33 is controlled to extract the cleaning liquid in the liquid storage tank 31 and deliver it to the cavity 211. The cleaning liquid is sprayed out through the liquid outlet 212. The motor 221 rotates the stirring shaft 2, driving the multiple stirring rods 21 to rotate around the stirring shaft 2. The cover plate 12 is then moved up and down by the electric push rod 11, so that the multiple stirring rods 21 rotate around the stirring shaft 2 and move up and down at the same time, thereby fully cleaning the inside of the polyester polyurethane.

[0066] Step 2: During the flushing process, the liquid pump 41 is controlled to be turned on. When the cleaning liquid is sprayed from the liquid port 212 to flush the polyester polyurethane, the waste water generated flows through the filter plate 13 into the lower cavity 15. The waste liquid in the lower cavity 15 is connected to the liquid pump 41. When the liquid pump 41 extracts the waste liquid from the lower cavity 15, the waste liquid is filtered and then transported to the liquid storage tank 31 through the corrugated hose 43 to mix with the cleaning liquid, and then extracted by the liquid extraction pump 33.

[0067] Step 3: After the flushing is completed, the treatment box 1 is rotated on the support frame 7 by the motor 71, so that the discharge valve 16 and the drain valve 17 are tilted downward in the direction away from the treatment box 1 to discharge the wastewater and polyester polyurethane. When cleaning the inner wall of the treatment box 1, the liquid inlet pipe 32 is connected to the water pump, and water is transported into the liquid inlet pipe 32 through the water pump, and the inner wall of the treatment box 1 is flushed through the cooperation of the electric push rod 11 and the motor 221.

[0068] The working principle and use process of the present invention:

[0069] When the polyester polyurethane is processed and flushed, the cover plate 12 is moved away from the processing box 1 through the electric push rod 11, and a gap is formed between the cover plate 12 and the top of the processing box 1. The polyester polyurethane is fed into the processing box 1 through the gap. The polyester polyurethane is located in the upper cavity 14, and the liquid inlet pipe 32 is connected to the external cleaning liquid delivery pump. The cleaning liquid is delivered to the liquid inlet pipe 32 through the cleaning liquid delivery pump, and the cleaning liquid enters the liquid storage tank 31. The liquid extraction pump 33 is controlled to extract the cleaning liquid in the liquid storage tank 31 and deliver it to the cavity 211 through the connecting pipe, the rotating joint 35, and the liquid pipe 34. The cleaning liquid pushes the one-way valve 214 to open and is sprayed out through the liquid port 212, so that the polyester polyurethane can be sprayed with the cleaning liquid for flushing. At this time, the motor 221 is controlled to be turned on, and the output shaft of the motor 221 rotates through the bevel gear assembly 222 to rotate the stirring shaft 2, driving the multiple stirring rods 21 to rotate around the stirring shaft 2, and flushing the inside of the polyester polyurethane. Then, the cover plate 12 is moved up and down by the electric push rod 11, driving the stirring shaft 2 to move vertically, so that the multiple stirring rods 21 rotate around the stirring shaft 2 and move up and down at the same time, and comprehensively clean the inside of the polyester polyurethane. Instead of spraying the cleaning liquid on the top of the polyester polyurethane, the cleaning liquid is used to flush the polyester polyurethane from top to bottom, thereby improving the flushing effect of the polyester polyurethane, thereby reducing the use of the cleaning liquid and reducing the generation of wastewater.

[0070] During the flushing process of the polyester polyurethane, the liquid pump 41 is controlled to be turned on at the same time. When the cleaning liquid sprayed from the liquid outlet 212 flushes the polyester polyurethane, the waste water generated flows through the filter plate 13 into the lower cavity 15, and flows into the filter housing 51 through the straight pipe. It is connected to the liquid pump 41 through the connecting hose 42. The liquid pump 41 is turned on to extract the waste liquid in the lower cavity 15 and transport it to the liquid storage tank 31 through the corrugated hose 43. The waste liquid is mixed with the cleaning liquid and then transported to the cavity 211 to flush the polyester polyurethane, so that the cleaning liquid after flushing the polyester polyurethane is reused, thereby reducing the use of the cleaning liquid and further reducing the generation of waste water. During the operation of the liquid pump 41, when the waste liquid is transported to the liquid storage tank 31, the activated carbon particles come into contact with the waste liquid, and harmful substances such as polyester polyurethane particles in the waste liquid can be adsorbed and filtered, effectively avoiding the cross contamination caused by the mixing of the waste liquid and the cleaning liquid, thereby improving the flushing effect of the waste liquid and the mixed liquid on the polyester polyurethane, and further reducing the generation of waste water. The amount of cleaning liquid used is further reduced, and the generation of waste water is further reduced. When the waste liquid flows into the liquid storage tank 31 through the corrugated hose 43, it flows into the inclined hole 631 located below the corrugated hose 43. The waste liquid flows into the inclined hole 631 and is stored. As a result, under the action of the gravity of the waste liquid, the annular fixing plate 63 rotates around the rotating rod 61, and the rotating rod 61 rotates in the liquid storage tank 31. When the annular fixing plate 63 rotates, the inclined hole 631 storing the waste liquid opens downward, and the waste liquid can flow into the liquid storage tank. 31, so that the waste liquid and the cleaning liquid are mixed; and when the annular fixing plate 63 rotates, the rotating rod 61 rotates in the liquid storage tank 31, so that there is no need to apply additional power to the rotating rod 61, thereby reducing the energy consumption of the equipment; in addition, when the annular fixing plate 63 rotates around the rotating rod 61, the annular fixing plate 63 contacts the mixture of the waste liquid and the cleaning liquid, thereby pushing the mixed liquid to flow to the outside of the annular fixing plate 63 and contact the inner wall of the liquid storage tank 31 before flowing in the opposite direction, further improving the mixing effect of the waste liquid and the cleaning liquid;

[0071] After the flushing is completed, the processing box 1 is rotated on the carrier 7 by the motor 71, so that the discharge valve 16 and the drain valve 17 are tilted downward in the direction away from the processing box 1. The discharge valve 16 and the drain valve 17 are opened to achieve a more thorough discharge of the wastewater and the polyester polyurethane. After the wastewater and the polyester polyurethane are discharged, when the inner wall of the processing box 1 is cleaned, the liquid inlet pipe 32 is connected to the water pump, and water is transported into the liquid inlet pipe 32 by the water pump. The electric push rod 11 and the motor 221 cooperate to make the multiple stirring rods 21 rotate around the stirring shaft 2 and move up and down at the same time, so as to flush the inner wall of the processing box 1.

[0072] When replacing the activated carbon particles, the fixing of the sealing plate 52 and the filter shell 51 by the buckle is cancelled, and the blocking of the opening of the filter shell 51 by the sealing plate 52 can be cancelled. At this time, the activated carbon particles can be discharged through the opening end of the filter shell 51 for replacement.
