[0022] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] Reference Figure 1-5 This invention specifically provides a pretreatment and purification device for water extraction, concentration, steam condensation, and recovery of traditional Chinese medicine granules, including a tank 1. A separation component 2 is provided at the top of the tank 1, a cooling component 3 is provided on the outside of the separation component 2, a filter component 4 is provided at the bottom of the separation component 2 and communicates therewith, a water storage component 5 is provided at the bottom of the filter component 4, a diversion component 6 for changing the direction of water flow is provided inside the water storage component 5, a cleaning component 7 is provided inside the water storage component 5 and communicates with the diversion component 6, a collection component 8 for storing cleaning wastewater is provided inside the water storage component 5, and a dehydration component 9 is provided inside the collection component 8.

[0024] The separation assembly 2 includes a separation box 21. The separation box 21 is fixedly installed at the top of the inside of the tank 1. An air inlet 22 is connected to the left side of the separation box 21 and extends to the outside of the tank 1. A guide vane 23 is fixedly installed inside the air inlet 22. A corrugated plate 24 is fixedly installed inside the separation box 21. A drain outlet 25 is connected to the bottom of the separation box 21. An exhaust outlet 26 is connected to the right side of the separation box 21.

[0025] With the above structural configuration, the steam generated during drug production enters the separation chamber 21 through the air inlet 22. The guide vanes 23 at the steam inlet guide the steam entering the air inlet 22 through their own tangential arrangement, causing the steam to initially rotate or change direction when flowing into the separation chamber 21. The large droplets carried in the steam are initially thrown out by inertia and the steam is evenly distributed. As the steam flows, the multi-layered staggered corrugated plates 24 force the steam to make multiple sharp turns. Water droplets collide with the walls due to inertia and collect into a liquid film that flows down. The separated condensate and drug droplets converge here, and at the same time, some drug residue is adsorbed together with the condensate. After converging at the bottom of the separation chamber 21, the steam is discharged into the wastewater tank 54 through the drain outlet 25. The steam that has undergone preliminary purification and separation enters the cooling component 3 through the exhaust outlet 26 for condensation.

[0026] The cooling assembly 3 includes a shell 31. The shell 31, which is connected to the exhaust port 26, is fixedly installed inside the tank 1. A heat exchange tube bundle 32 is fixedly installed inside the shell 31. Several baffles 33 are fixedly installed inside the shell 31. A water outlet is fixedly installed at the bottom of the shell 31.

[0027] With the above structural setup, after the separation component 2 separates the medicinal liquid and dregs carried in the steam, the relatively clean steam enters the interior of the shell 31 through the exhaust port 26. The baffle plate 33 guides the flow direction of the steam. The flowing steam is in contact with the cooling medium in the heat exchange tube bundle 32 for a long time, and the steam can condense into condensate more quickly. The condensate flows into the filter box 41 through the outlet for filtration.

[0028] The filter assembly 4 includes a filter box 41, which is fixedly installed inside the tank 1. A filter screen 42 is slidably installed inside the filter box 41. A water collection hopper 43 is provided at the bottom of the filter screen 42. A filter element 44 is connected to the bottom of the water collection hopper 43. An activated carbon plate 45 is provided at the bottom of the filter element 44.

[0029] With the above structural setup, after the condensate flows into the filter box 41, the filter screen 42 performs preliminary filtration on the condensate to remove larger impurities. After filtration, the condensate flows along the water collection hopper 43 into the filter element 44 for secondary precision filtration to remove smaller impurities. Finally, the activated carbon plate 45 adsorbs particulate matter in the water, thus completing the purification of the condensate.

[0030] The water storage component 5 includes a water storage tank 51, which is connected to the outlet of the tank 1. A partition plate 52 is provided inside the water storage tank 51 to separate its internal space. The left space of the water storage tank 51 is a purified water tank 53, and the right space is a wastewater tank 54.

[0031] With the above structural arrangement, the partition plate 52 divides the water storage tank 51 into a purified water tank 53 and a wastewater tank 54, which are used to store clean condensate and wastewater generated during production and cleaning, respectively, for later use and treatment of the water in the purified water tank 53 and the wastewater tank 54.

[0032] The diversion component 6 includes a detection box 61, the inlet of which is connected to the outlet of the drain 25. A conductivity sensor 62 is fixedly installed inside the detection box 61. A three-way pipe 63 is fixedly installed at the outlet of the detection box 61. A reuse branch valve 64 is connected to the three-way pipe 63. The outlet of the reuse branch valve 64 is connected to the water storage tank 51.

[0033] With the above-mentioned structure, the condensate to be tested flows into the test chamber 61 and passes through the conductivity sensor 62 to detect the degree of dissolved organic matter / ions / pharmaceutical pollution in the water. Based on the test results, different signals are transmitted to the reuse branch valve 64 on the three-way pipe 63. If the test is qualified, the normally open solenoid valve introduces the water source into the purified water tank 53. If the test is unqualified, the normally closed solenoid valve introduces the water source into the wastewater tank 54.

[0034] The cleaning assembly 7 includes a cleaning pipe 71. The cleaning pipe 71 is fixedly installed on the top of the filter element 44. A backwash pump 72 connected to the cleaning pipe 71 is fixedly installed inside the purified water tank 53. Several backwash nozzles 73 are fixedly installed on the cleaning pipe 71. The several backwash nozzles 73 are located inside the filter element 44. The other end of the cleaning pipe 71 passes through and extends into the separation box 21. One end of the cleaning pipe 71 is connected to a backwash nozzle 73 located near the air inlet 22.

[0035] With the above-mentioned structure, the condensate in the purified water tank 53 is drawn out by the backwash pump 72 and then transported to the backwash nozzle 73 through the cleaning pipe 71 to rinse the filter element 44 from the inside out, so that the waste attached to the surface of the filter element is removed, the service life of the filter element 44 is extended, and finally the water flows into the wastewater tank 54 through the drain outlet.

[0036] The collection component 8 includes a wastewater pipe 81. The wastewater tank 54 is connected to the wastewater pipe 81. The wastewater pipe 81 is connected to the separation box 21 and the filter box 41 respectively. A drain valve is fixedly installed at the connection between the separation box 21 and the filter box 41 and the wastewater pipe 81. The wastewater tank 54 is equipped with a dehydration component 9.

[0037] With the above structural setup, the wastewater generated during production and cleaning flows directly into the wastewater tank 54 through the drain valve, and then undergoes solid-liquid separation through the dewatering component 9, which facilitates the separate treatment of wastewater and waste residue in the future.

[0038] The dehydration component 9 includes a drive motor 91. The drive motor 91 is fixedly installed at the bottom of the wastewater tank 54. A dehydration bucket 92, which is connected to the drive motor 91, is rotatably installed at the bottom of the wastewater tank 54. A drainage trough 93 is provided on the outside of the dehydration bucket 92 and is connected to the drain outlet.

[0039] With the above-mentioned structural setup, the wastewater entering the dewatering tank 92 and the solid waste are trapped inside the tank. The wastewater flows into the drainage trough 93 on the outside through the water leakage hole on the tank. At the same time, the drive motor 91 is started, which drives the dewatering tank 92 to rotate. The centrifugal force generated by the rotation throws out the wastewater adsorbed in the waste and discharges it, separating the waste and wastewater, keeping the waste in a dry state for easy collection and treatment. The wastewater is finally discharged into the wastewater collection container outside the equipment for centralized collection and treatment.

[0040] The filter box 41 has a sliding seat 411 fixedly installed inside, and a positioning block 412 is provided inside the sliding seat 411. The filter screen 42 and the activated carbon plate 45 are provided with positioning grooves 413 that are adapted to the positioning block 412.

[0041] With the above-mentioned structure, the filter screen 42 and the activated carbon plate 45 are fixed in the sliding seat 411 by the positioning block 412 and the positioning groove 413. At the same time, the filter screen 42 and the activated carbon plate 45 can be quickly removed from the sliding seat 411 when they need to be removed and replaced, which is convenient for the staff to replace.

[0042] Working principle: Steam is input into the separator 21 through the air inlet 22. The steam turns multiple times during its flow through the guide vanes 23 and the corrugated plate 24, separating the heavier substances such as medicine liquid and dregs entrained inside. The steam flows to the bottom of the separator 21 with the condensate. Then the condensate mixes with the waste and is discharged into the wastewater tank 54 through the drain outlet 25. The remaining steam enters the cooling component 3 through the exhaust outlet 26. The steam comes into contact with the cooling medium in the heat exchange tube bundle 32 under the guidance of the baffle plate 33, cools down and condenses into condensate. The condensate flows to the bottom of the shell 31 and then flows into the filter box 41. The impurities in the water are purified by three layers of filtration to obtain clean cooling water. After passing the conductivity sensor 62, the water finally enters the purified water tank 53 for storage.

[0043] After the work is completed, the backwash pump 72 draws clean water from the purified water tank 53 and delivers it to the separation tank 21 and the filter tank 41 through the cleaning pipe 71. The backwash nozzle 73 pressurizes the water flow to wash the dirt attached to the inside of both tanks. The wastewater generated flows into the wastewater tank 54 along the wastewater pipe 81 and is finally separated into solid and liquid by the dewatering component 9 together with the wastewater generated during the production process.
