Technical Field
[0001] This utility model relates to the field of low thermal conductivity concrete processing technology, specifically to a batching device for low thermal conductivity concrete production. Background Technology
[0002] Low thermal conductivity concrete is a general term for a group of refractory concretes, composed of refractory lightweight aggregates or powders, binders, and admixtures. Depending on the type of binder, it can be classified as refractory concrete with cementitious binders, organic binders, inorganic binders, or composite binders.
[0003] When producing low thermal conductivity concrete, the raw materials need to be preheated and mixed with hot water when the ambient temperature is low. The mixing device can prevent the concrete from solidifying, but it cannot maintain the temperature of the internal mixing environment, so the concrete slurry needs to be heated additionally during pouring, which is very inconvenient.
[0004] Now, a novel batching device for producing low thermal conductivity concrete is proposed to solve the above problems. Utility Model Content

The tank is installed at the center of the bottom of the outer shell, and a motor is installed at the center of the bottom of the tank. A stirring rod is movably connected to the center of the lower part of the tank. A liquid storage tank is formed between the outer shell and the tank. Limiting sleeves are fixed on both sides of the inner shell, and an electric heating tube is horizontally fixed between the limiting sleeves. A motor is installed at the upper right corner of the outer shell. A cover plate is fixed to the top of the output shaft of the motor, and a pressure pump is installed at the top of the cover plate. An inlet pump is installed at the upper left corner of the inner shell, and an outlet pump is installed at the lower right corner of the inner shell.
[0007] As a further technical solution of this utility model, the limiting sleeve is symmetrically sleeved on both sides of the outside of the electric heating tube, and the electric heating tube and the liquid storage tank are arranged in concentric circles.
[0008] As a further technical solution of this utility model, a groove is provided at the lower part of the inside of the cover plate, and a sealing plate is movably connected between the two sides of the groove. Threaded plates are fixed above the two sides of the sealing plate. An inner cavity is provided at the upper part of the inner side of the cover plate, and a lead screw is longitudinally mounted on both sides of the inner cavity.

A rotating shaft is movably connected between the two sides of the upper part of the inner cavity, and a bevel gear I is welded to both sides of the rotating shaft. A motor II is installed above the left side of the cover plate.
[0009] As a further technical solution of this utility model, the right side of the output shaft of the second motor is fixedly connected to the rotating shaft, and the second bevel gear is meshed with the side of the bottom of the first bevel gear.
[0010] As a further technical solution of this utility model, the threaded plate is sleeved on the outside of the lead screw, and the threaded plate can slide up and down along the side wall of the groove as a sealing plate.
[0011] As a further technical solution of this utility model, a hose is installed at the lower left corner between the tank body and the outer shell, and a left valve is installed on the hose. The top end of the hose is fixed with a pipe opening, and a retainer is fixed at the center of the left side of the outer shell.
[0012] As a further technical solution of this utility model, a rubber sleeve is fixed to the lower right corner of the outer shell, and a plug rod is movably inserted into the inside of the rubber sleeve. A balance plate is fixed to the bottom of the plug rod, and a corrugated pipe is installed between the outer shell and the tank on the left side of the top of the balance plate. A right valve is installed above the corrugated pipe, and a trolley is provided on the right side below the outer shell.
[0013] As a further technical solution of this utility model, the insertion rod can slide vertically along the inner wall of the rubber sleeve, and the balance plate can vertically compress the corrugated pipe.
[0014] Compared with the prior art, the beneficial effects of this utility model are: the batching device for low thermal conductivity concrete production not only achieves uniform heating of the concrete slurry in the tank and avoids excessive temperature loss in the tank, but also enables a variety of discharge methods;
[0015] (1) By fixing electric heating tubes horizontally between the limiting sleeves, an annular liquid storage tank is formed between the outer shell and the inner tank for the device to store water. After turning on the liquid pump, clean water is injected into the liquid storage tank. Under the circuit control of the controller, the power is turned on and the electric heating tubes installed between the two limiting sleeves are started to heat the clean water. Then, the cover plate is connected to the top of the outer shell by the motor to avoid the temperature loss too fast and affect the temperature rise of the internal concrete slurry.

Under the restriction of the inner cavity, the threaded plate and the sealing plate are vertically upgraded, forcing the sealing plate to be inserted into the top of the outer shell, so as to prevent the heat generated by heating in the liquid storage tank inside the outer shell from being lost. Then the cover plate is removed and the tank is cleaned.
[0017] (3) A hose is installed at the lower left corner between the tank and the outer shell. A corrugated pipe is installed between the outer shell and the tank at the left side of the top of the balance plate. When the motor rotates the stirring rod to scrape the inner wall of the outer shell, the pressure pump is started. The left valve or the right valve on the left side can be opened. After removing the tube from the sleeve, the material is introduced into the storage device. When the trolley is pushed to the lower right of the outer shell, the insertion rod is pulled along the rubber sleeve so that the balance plate guides the corrugated pipe to sink until the bottom of the corrugated pipe is embedded in the trolley for discharge.

[0024] Please see Figure 1-4 An embodiment of this utility model provides a batching device for producing low thermal conductivity concrete, comprising an outer shell 1 and a tank 10. The tank 10 is installed at the center of the bottom of the outer shell 1, and a motor 16 is installed at the center of the bottom of the tank 10.

[0025] The limiting sleeves 19 are symmetrically fitted on both sides of the outside of the electric heating tube 3, and the electric heating tube 3 and the liquid storage tank 2 are arranged in concentric circles;
[0026] Specifically, such as Figure 1 and Figure 2 As shown, an annular liquid storage tank 2 is formed between the outer shell 1 and the inner tank 10 for the device to store water. After the liquid inlet pump 9 is turned on, clean water is injected into the liquid storage tank 2. Under the circuit control of the controller, the power is turned on, and the electric heating tube 3 installed between the two limit sleeves 19 is started to heat the clean water. Then, the cover plate 5 is rotated by the motor 4 and attached to the top of the outer shell 1.
[0027] A groove 26 is provided at the bottom inside the cover plate 5, and a sealing plate 8 is movably connected between the two sides inside the groove 26. Threaded plates 24 are fixed above the two sides of the sealing plate 8. An inner cavity 25 is provided at the top inside the cover plate 5, and a lead screw 23 is longitudinally mounted on the two sides inside the inner cavity 25. A bevel gear 22 is fixed at the top of the lead screw 23. A rotating shaft 20 is movably connected between the two sides above the inner cavity 25, and a bevel gear 21 is welded to the two sides of the rotating shaft 20. A motor 7 is installed above the left side of the cover plate 5.
[0028] The output shaft of motor 27 is fixedly connected to the right side of the rotating shaft 20. Bevel gear 22 is meshed with the side of the bottom of bevel gear 1 21. Threaded plate 24 is sleeved on the outside of screw 23. Threaded plate 24 can slide up and down along the side wall of groove 26 to seal plate 8.
[0029] Specifically, such as Figure 1 and Figure 3 As shown, after starting the second motor 7, the rotating shaft 20 is rotated, and the two symmetrical bevel gears 21 mesh with the lower bevel gear 22 and the lead screw 23. Under the constraint of the inner cavity 25, the threaded plate 24 and the sealing plate 8 are vertically upgraded, forcing the sealing plate 8 to be inserted into the upper part of the outer shell 1, thus preventing the heat generated by heating in the liquid storage tank 2 inside the outer shell 1 from being lost.
[0030] A hose 13 is installed at the lower left corner between the tank body 10 and the outer shell 1, and a left valve 15 is installed on the hose 13. A pipe opening 11 is fixed at the top of the hose 13. A clamp 12 is fixed at the center of the left side of the outer shell 1. A rubber sleeve 27 is fixed at the lower right corner of the outer shell 1. An insert rod 28 is movably inserted into the inside of the rubber sleeve 27. A balance plate 29 is fixed at the bottom of the insert rod 28. A bellows 30 is installed between the outer shell 1 and the tank body 10 through the left side of the top of the balance plate 29.

[0031] Specifically, such as Figure 1 and Figure 4 As shown, a bellows 30 is installed on the left side of the top of the balance plate 29, passing between the outer shell 1 and the tank 10. When the motor 316 rotates the stirring rod 14 to scrape the inner wall of the outer shell 1, the left valve 15 or the right valve 31 on the left side can be opened. After removing the tube port 11 from the sleeve 12, the material is introduced into the storage device. When the trolley 17 is pushed to the lower right of the outer shell 1, the insertion rod 28 is pulled along the rubber sleeve 27 so that the balance plate 29 guides the bellows 30 to sink until the bottom of the bellows 30 is embedded in the trolley 17 for discharge, avoiding slurry splashing and polluting the environment.
[0032] Working Principle: In use, refractory lightweight aggregate or powder, binder, and additives are added into the inner tank 10. An annular liquid storage tank 2 is formed between the outer shell 1 and the inner tank 10 for water storage. After the inlet pump 9 is turned on, clean water is injected into the liquid storage tank 2. Under the circuit control of the controller, the power is turned on, and the electric heating tube 3 installed between the two limit sleeves 19 is activated to heat the clean water. Then, the cover plate 5 is rotated by the motor 4 and attached to the top of the outer shell 1. After the motor 7 is started, the rotating shaft 20 is rotated, and the two symmetrical bevel gears 21 mesh with the lower bevel gear 22 and the screw 23, which vertically push the screw under the constraint of the inner chamber 25. Plate 24 and sealing plate 8 force sealing plate 8 to be inserted into the upper part of the outer shell 1 to prevent heat loss from the liquid storage tank 2 inside the outer shell 1 due to heating. The left side of the top of the balance plate 29 passes through the space between the outer shell 1 and the tank 10 and is equipped with a bellows 30. When the motor 3 16 rotates the stirring rod 14 to scrape the inner wall of the outer shell 1, the left valve 15 or the right valve 31 on the left side can be opened. After removing the tube port 11 from the sleeve 12, the material is introduced into the storage device. When the trolley 17 is pushed to the lower right of the outer shell 1, the insertion rod 28 is pulled along the rubber sleeve 27 so that the balance plate 29 guides the bellows 30 to sink until the bottom of the bellows 30 is embedded in the trolley 17 for discharge.
