Description

Technical Field

[0001] This utility model relates to the field of sodium bicarbonate production and processing technology, specifically to a sodium bicarbonate alkaline material conveying device. Background Technology

[0002] Alkali solution is a key raw material for the production of baking soda. Its aqueous solution reacts with lime water to produce sodium bicarbonate and sodium hydroxide. When the temperature of the alkali solution decreases, crystals will precipitate. Therefore, when the alkali solution is transported through pipelines, especially long pipelines, the alkali solution will gradually cool down in the pipeline and crystallize at the end valve. Over time, the accumulation of crystals will cause the valve to become blocked, resulting in poor drainage of the alkali solution. There will also be some resistance when opening and closing the valve. Therefore, further improvements can be made. Utility Model Content

[0004] As an optimization, the insulation component includes an insulation pipe inserted into the mounting hole, the insulation pipe surrounding the outside of the delivery pipe, an annular shell fitted at the end of the delivery pipe, and the end of the insulation pipe communicating with the annular shell. A return pipe is connected to the bottom of the annular shell, and a hot water tank is connected to the beginning of the insulation pipe. The insulation pipe and the return pipe are circulated through a water pump.

[0005] As an optimization, one end of the insulation pipe is formed into a butt joint by an annular cut on the outer side, and the outer side of the butt joint is provided with an external thread. The other end of the insulation pipe is provided with a slot corresponding to the butt joint, and the inner wall of the slot is provided with an internal thread corresponding to the external thread. The butt joint is inserted into the slot and is tightened and positioned by the slot engaging with the internal thread.

[0007] As an optimization, the heat insulation component includes four heat insulation plates arranged in an array, and the four heat insulation plates are arranged in a ring around the outside of the heat insulation pipe.

[0008] As an optimization, an elastic arc-shaped clamping plate is fixedly installed on the inner arc side of the heat insulation board, and the arc-shaped clamping plate is clamped on the outside of the heat insulation pipe. A pull handle is fixedly installed on the outer arc side of the heat insulation board.

[0009] As an optimization, the insulation board is composed of a rock wool layer, a polyurethane foam layer and a ceramic insulation board, with the ceramic insulation board located between the rock wool layer and the polyurethane foam layer.

[0020] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-2 A sodium bicarbonate solution material conveying device includes a conveying pipe 1 for conveying the solution, flanges 2 for docking at both ends of the conveying pipe 1, a plurality of mounting holes arranged in an array near the interior of the conveying pipe 1, a valve 3 fixedly installed at the end of the conveying pipe 1 through the flanges 2, a heat insulation component 4 for maintaining the temperature inside the conveying pipe 1 is provided on the outside of the conveying pipe 1, and a heat insulation component 5 for heat preservation is provided on the outside of the heat insulation component 4.

[0023] Please see Figure 2-3 The insulation component 4 includes an insulation pipe 6 inserted into the mounting hole. The insulation pipe 6 surrounds the outside of the conveying pipe 1. An annular shell 7 is fitted at the end of the conveying pipe 1, and the end of the insulation pipe 6 is connected to the annular shell 7. A return pipe 8 is connected to the bottom of the annular shell 7. A hot water tank is connected to the beginning of the insulation pipe 6, and the insulation pipe 6 and the return pipe 8 are connected by a water pump for circulation. By starting the water pump, hot water can be introduced into the insulation pipe 6, which will maintain the temperature outside the conveying pipe 1 and prevent the alkali solution from cooling down, crystallizing and accumulating, and clogging the valve 3 as the transmission length increases. The hot water will circulate from the annular shell 7 along the return pipe 8, thereby maintaining a stable temperature and preventing the alkali solution from crystallizing.

[0024] Please see Figure 4One end of the insulation pipe 6 is cut into a ring to form a docking part 9. The outer side of the docking part 9 is provided with an external thread 10. The other end of the insulation pipe 6 is provided with a slot 11 corresponding to the docking part 9. The inner wall of the slot 11 is provided with an internal thread 12 corresponding to the external thread 10. The docking part 9 is inserted into the slot 11 and is tightened and positioned by the slot 11 and the internal thread 12. By inserting the docking part 9 inserted into the end of one insulation pipe 6 into the slot 11 in the end of another insulation pipe 6 and turning clockwise to tighten the external thread 10 and the internal thread 12, the docking installation can be completed, which is convenient for installation and disassembly.

[0025] Please see Figure 4 A rubber sealing ring 13 is provided on the outer side of the docking part 9. A groove 14 is provided on the inner wall of the slot 11 corresponding to the rubber sealing ring 13, and the rubber sealing ring 13 is embedded in the groove 14. By docking the two heat insulation pipes 6, the rubber sealing ring 13 will be tightly embedded in the groove 14, thereby improving the sealing effect.

[0026] Please see Figure 5-6 The heat insulation component 5 includes four arrayed heat insulation plates 15, which are arranged in a ring around the outside of the insulation pipe 6. The heat insulation plates 15 are composed of a rock wool layer 18, a polyurethane foam layer 19, and a ceramic insulation plate 20, with the ceramic insulation plate 20 located between the rock wool layer 18 and the polyurethane foam layer 19. By surrounding the insulation pipe 6 with the four heat insulation plates 15, the heat insulation effect can be achieved, minimizing the rate of heat loss inside the insulation pipe 6. A flexible arc-shaped clamping plate 16 is fixedly installed on the inner arc side of the heat insulation plate 15, and the arc-shaped clamping plate 16 is clamped on the outside of the insulation pipe 6. A pull handle 17 is fixedly installed on the outer arc side of the heat insulation plate 15. By pressing the heat insulation plate 15, the arc-shaped clamping plate 16 is clamped on the outside of the insulation pipe 6, thus installing and positioning the heat insulation plate 15. When disassembling, the heat insulation plate 15 can be removed simply by pulling the pull handle 17.

[0027] When in use, first insert the insulation pipe 6 into the installation hole, then insert the mating part 9 of the end of another insulation pipe 6 into the slot 11 inside the end of the insulation pipe 6, and after turning clockwise, the external thread 10 will engage with the internal thread 12 to tighten, thereby completing the mating installation. Similarly, install the insulation pipes 6 one by one around the outside of the conveying pipe 1, and then insert the end of the insulation pipe 6 into the annular shell 7. After that, the water pump can be started to introduce hot water into the insulation pipe 6, and the hot water will circulate from the annular shell 7 along the return pipe 8, thereby maintaining the temperature of the outside of the conveying pipe 1.

[0028] At the same time, by pressing the heat insulation plate 15, the arc-shaped clamping plate 16 is clamped on the outside of the insulation pipe 6, and the heat insulation plate 15 can be installed and positioned so that the four heat insulation plates 15 are arranged in a ring around the outside of the insulation pipe 6, thereby playing a heat preservation role and minimizing the rate of heat loss inside the insulation pipe 6. When disassembling, the heat insulation plate 15 can be removed simply by pulling the handle 17.

[0029] In summary, this baking soda alkali material conveying device, by sequentially installing insulation pipes 6 around the outside of the conveying pipe 1 and connecting multiple insulation pipes 6 through an annular shell 7, allows the water pump to be started to introduce hot water into the insulation pipes 6. The hot water circulates from inside the annular shell 7 along the return pipe 8, thereby maintaining the temperature outside of the conveying pipe 1 and minimizing the accumulation of alkali crystals and blockage of valve 3 as the conveying length cools down. This ensures a stable temperature and prevents alkali crystallization.

[0030] By pressing the heat insulation plate 15, the arc-shaped clamping plate 16 is clamped onto the outside of the insulation pipe 6, thus installing and positioning the heat insulation plate 15. This allows the four heat insulation plates 15 to surround the outside of the insulation pipe 6 in a ring shape, thereby achieving the heat insulation effect, minimizing the rate of heat loss inside the insulation pipe 6, further improving the heat insulation effect, further delaying the decrease in the temperature of the alkali solution, and maintaining the temperature of the alkali solution inside the pipe.
