DETAILED DESCRIPTION

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] See also Figure 1-9 The present invention provides a technical solution: a high-efficiency heat pump low-temperature evaporation concentrator, comprising a tank body 1, a bearing plate 2, a heating rod 3, a round hole 4, a connecting plate 5, a storage barrel 6, a feeding pipe 7, a first connecting shaft 8, a sealing plate 9, a first connecting member 10, a belt 11, a second connecting member 12, a second motor 13, a second connecting shaft 14, a first bevel gear 15, a second bevel gear 16, a third connecting shaft 17, a third motor 18, a first stirring rod 19, a second stirring rod 20, Guide pipe 21, box body 22, guide plate 23, extrusion plate 24, adjustment plate 25, circular gear 26, fourth connecting shaft 27, fourth motor 28, conveying cylinder 29, discharge pipe 30, rotating shaft 31, fifth motor 32, blade 33, first connecting pipe 34, condenser 35, vacuum pump 36, second connecting pipe 37 and water tank 38, tank body 1, the inner middle and upper end of tank body 1 is fixedly connected with a bearing plate 2 which plays a bearing role, and the bottom end of tank body 1 is integrally connected with guide pipe 21;

[0051] A heating rod 3 is installed at an equal angle on the upper end of the carrying plate 2, and a feeding structure and a stirring structure are respectively arranged on the outer side and the lower side of the carrying plate 2, wherein the feeding structure includes a storage barrel 6, a feeding pipe 7, a first connecting shaft 8, a sealing plate 9, a first connecting member 10, a belt 11, a second connecting member 12 and a second motor 13, and the stirring structure includes a second connecting shaft 14, a first bevel gear 15, a second bevel gear 16, a third connecting shaft 17, a third motor 18, a first stirring rod 19 and a second stirring rod 20;

[0052] The lower end of the guide tube 21 is fixedly connected to the upper left end of the box body 22, and the upper end of the box body 22 is bolted to the tank body 1, and the left wall of the box body 22 is symmetrically slidably connected to the guide plate 23, and the right end of the guide plate 23 is embedded and connected to the left end of the extrusion plate 24, and the middle position of the left end of the extrusion plate 24 is fixedly connected to the adjustment plate 25;

[0053] When using this high-efficiency heat pump low-temperature evaporation concentrator, Figure 1 , Figure 4 , Figure 6 , Figure 7 and Fig. 9, since the front and rear ends of the tank body 1 are both symmetrically inlaid with the feed pipe 7, the diameter of the sealing plate 9 is equal to the inner diameter of the lower end of the storage barrel 6, the first connecting member 10 is transmission-connected with the second connecting member 12 through the belt 11, the inner end diameter of the first connecting member 10 is larger than the inner end diameter of the second connecting member 12, and the sealing plate 9 is in a flip structure inside the storage barrel 6 through the second connecting member 12 and the first connecting member 10;

[0054] Therefore, the heating rods 3 distributed at equal angles are made to work, and the water inlet pipe is bolted to the middle position of the top of the tank body 1, so that the sewage enters the tank body 1 through the water inlet pipe, and the sewage falls on the upper end of the supporting plate 2 along the circular hole 4, and enters the middle and lower end of the tank body 1 through the hollow structure of the supporting plate 2, and the sewage flows evenly on the outer wall of the heating rod 3, and the temperature of the heating rod 3 is increased, so that the sewage on the outer wall of the heating rod 3 is evaporated and concentrated at low temperature. By heating only the sewage flowing on the outer wall of the heating rod 3 instead of heating the sewage as a whole, not only the temperature of the entire low-temperature evaporation concentrator is lowered, but also more energy can be saved;

[0055] When it is necessary to add flocculant, the sealing plate 9 is in a horizontal state to seal the lower end of the inner part of the storage barrel 6, and the flocculant is poured into the storage barrel 6 set at an equal angle. When the flocculant in the storage barrel 6 reaches an appropriate amount, the second motor 13 is operated to drive the second connecting member 12 and the first connecting shaft 8 on the left to rotate. When the second connecting member 12 rotates, the first connecting member 10 is driven to rotate through the belt 11, and the first connecting member 10 drives the first connecting shaft 8 on the right to rotate. When the left and right groups of first connecting shafts 8 rotate, all the sealing plates 9 are turned over and are in a vertical state, so that the flocculant in the storage barrel 6 enters the interior of the tank body 1 from the periphery of the tank body 1 through the feeding pipe 7. The cross-sections of the first connecting member 10 and the second connecting member 12 are both "I"-shaped structures, which can prevent the belt 11 from detaching from the first connecting member 10 and the second connecting member 12, thereby preventing burns when adding flocculants, and facilitating the flocculant to be evenly distributed in the tank body 1;

[0056] like Figure 1 , Figure 3 and Figure 8 , since the right end of the first bevel gear 15 is meshedly connected with the second bevel gear 16, the inner wall of the bottom end of the tank body 1 matches the shape of the first stirring rod 19, and the first stirring rod 19 is in a rotating structure inside the tank body 1 through the second bevel gear 16 and the first bevel gear 15. Therefore, after the flocculant is added to the inside of the tank body 1, the third motor 18 is driven to drive the third connecting shaft 17 to rotate on the tank body 1. When the third connecting shaft 17 rotates, it drives the second bevel gear 16 to rotate, so that the second bevel gear 16 is meshed with the first bevel gear 15 to drive the second connecting shaft 14 to rotate;

[0057] When the second connecting shaft 14 rotates, it drives the second stirring rods 20 set at equal intervals and the first stirring rods 19 set at equal angles to rotate, so that the first stirring rods 19 and the second stirring rods 20 stir the sewage and the flocculant, and the flocculant flocculates the impurities in the sewage to form large particle flocs. When the vacuum pump 36 is working, the water vapor inside the tank body 1 enters the condenser 35 through the first connecting pipe 34 for treatment, and the water vapor condenses and enters the inside of the water tank 38 through the second connecting pipe 37 for collection, so that the sewage is fully in contact with the flocculant.

[0058] like Figure 1 , Figure 2 , Figure 3 and Figure 5 , since the lower end of the adjusting plate 25 is meshedly connected with the circular gear 26, the extruding plate 24 is in a sliding structure inside the box body 22 through the adjusting plate 25 and the circular gear 26, and the extruding plate 24 is a porous structure, and the left wall of the box body 22 is symmetrically slidably connected with the guide plate 23, and the outer surface of the rotating shaft 31 is a blade 33 with a spiral structure, and the box body 22 is connected with the discharge pipe 30 through the blade 33;

[0059] Therefore, after one concentration, the control valve on the guide pipe 21 is opened to allow the mixture at the bottom of the tank body 1 to enter the interior of the box body 22 through the guide pipe 21, and then the control valve on the extrusion plate 24 is closed. When the fourth motor 28 is working, it drives the fourth connecting shaft 27 to rotate, and the fourth connecting shaft 27 drives the circular gear 26 to rotate, so that the circular gear 26 is engaged with the adjustment plate 25, and the adjustment plate 25 is moved rightward on the left wall of the box body 22, so that the guide plate 23 symmetrically arranged front and back pushes the extrusion plate 24 to move stably to the right, so that the extrusion plate 24 squeezes the flocculants in the box body 22;

[0060] Excess water in the flocculants enters the left end of the interior of the box 22 through the porous structure of the squeezing plate 24, pushing the concentrate to the left end of the conveying cylinder 29. When the fifth motor 32 is working, it drives the rotating shaft 31 to rotate, and the rotating shaft 31 drives the blades 33 to rotate, so that the spirally distributed blades 33 rotate to transfer the concentrate at the left end of the conveying cylinder 29 to the inside of the discharge pipe 30, and the water in the box 22 is discharged through the drainage pipe at its left front end, so as to facilitate the secondary concentration of the mixture after squeezing and precipitation, improve the concentration efficiency, and facilitate the discharge of the concentrate.
