Description

Technical Field

[0001] The utility model relates to the technical field of steam heating, in particular to a high-temperature gas conveying device. Background Art

[0002] A steam generator is provided on one side of a soybean milk machine. The high-temperature gas generated by the steam generator is conveyed to the soybean milk machine through a pipeline. To prevent the liquid in the soybean milk machine from entering the steam generator through the pipeline, a one-way valve is provided on the pipeline. The one-way valve is often arranged on the conveying pipeline outside the soybean milk machine. There is a corner between the conveying pipeline outside the soybean milk machine and the conveying pipeline inside the soybean milk machine. As a result, the liquid entering the conveying pipeline accumulates at the corner (90° bending position), causing the conveying pipeline to be blocked.

[0003] In addition, a water level sensor for detecting the liquid position height is provided in the steam generator. Since water is heated to generate steam and the steam flows in the inner cavity of the steam generator, scale adheres to the water level sensor after long-term use (such as when boiling water in a hot water kettle, scale will be generated on its inner wall and bottom wall). When scale adheres to the water level sensor, the detection accuracy of the water level sensor is affected. This causes the steam generator to operate abnormally, and further affects the high-temperature gas conveying capacity of the soybean milk machine. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a high-temperature gas conveying device, which sets the one-way valve inside the machine body, cancels the setting of the one-way valve at the corner between the conveying pipeline outside the soybean milk machine and the conveying pipeline inside the soybean milk machine, avoids the liquid of the soybean milk machine from entering the corner, and avoids the liquid at the corner from blocking the steam conveying pipe.

[0005] The purpose of the utility model is achieved as follows:

[0006] A high-temperature gas conveying device includes a conveying pipe structure arranged between the machine body and the steam generator. One end of the conveying pipe structure is connected to the steam generator, and the other end of the conveying pipe structure is connected to the machine body; a one-way valve for making the liquid flow unidirectionally and preventing the liquid from flowing along the conveying pipe structure to the steam generator is provided on the conveying pipe structure, and the one-way valve is located in the inner cavity of the machine body.

[0007] The conveying pipe structure extends into the inner cavity of the machine body from the side or bottom of the machine body.

[0008] The conveying pipe structure is integrally or segmentally disassembled and assembled on the machine body, which is convenient for the later operations of replacing, disassembling and repairing the conveying pipe structure.

[0009] The conveying pipe structure includes an external conveying section located outside the machine body and an internal conveying section located in the inner cavity of the machine body. A connecting part is provided between the external conveying section and the internal conveying section. The external conveying section and the internal conveying section are detachably connected through the connecting part, so that the external conveying section can be disassembled and assembled on the outside of the machine body.

[0010] The connecting part is arranged on the inner or outer side of the machine body.

[0011] The conveying pipe structure includes a vertical section located on the inner side of the machine body, and a one-way valve is arranged on the vertical section so that the liquid entering the conveying pipe structure flows back to the inner cavity of the machine body along the vertical section.

[0012] A silencer is arranged at the output end of the vertical section, and the silencer is provided with a plurality of hot air conveying holes communicating with the output end of the vertical section. The hot air is output from each hot air conveying hole of the silencer, avoiding the concentration of hot air at one place for output and effectively reducing the noise generated when the hot air is output.

[0013] The one-way valve is arranged on the vertical section, and the liquid entering the vertical section flows back to the machine body under the action of gravity, ensuring that the steam conveying pipe structure will not be blocked.

[0014] A stirring cavity is arranged in the machine body. The conveying pipe structure penetrates through one side of the stirring cavity from the side of the machine body and extends vertically in the stirring cavity, and the air outlet end of the conveying pipe structure is close to the bottom wall of the inner part of the stirring cavity;

[0015] Or, the conveying pipe structure penetrates through the bottom of the stirring cavity from the side of the machine body and extends vertically in the stirring cavity, and the air outlet end of the conveying pipe structure extends along the opening above the stirring cavity.

[0016] The high-temperature gas conveying device further includes a water replenishing tank externally arranged outside the steam generator, and the water replenishing tank is provided with a water level sensor for detecting the water level; a water inlet pipe and a ventilation pipe for balancing the air pressure between the steam generator and the water replenishing tank are arranged between the steam generator and the water replenishing tank.

[0017] The bottom of the water replenishing tank is provided with a water inlet part located below the water level sensor, and the side water inlet structure of the water replenishing tank is cancelled to avoid the floating ball of the water level sensor floating and failing due to the impact of the side water inlet of the water replenishing tank; the upper limit detection position of the water level sensor is lower than the ventilation position of the ventilation pipe on the water replenishing tank, avoiding the water in the water replenishing tank reaching the ventilation position.

[0018] The machine body is a soybean milk machine. A stirring cavity is arranged in the soybean milk machine. The soybean milk machine is provided with a stirring component at the bottom of the inner cavity of the stirring cavity. The stirring cutter head of the stirring component extends into the stirring cavity. The soybean milk machine is provided with a control device, and the control device is electrically connected to the stirring component.

[0019] A ventilation pipe for balancing the air pressures of each other is provided between the steam generator and the water replenishing tank. One end of the ventilation pipe is connected to the inner cavity of the steam generator, and the other end of the ventilation pipe is connected to the inner cavity of the water replenishing tank. Without the ventilation pipe, the steam generated by the steam generator makes the air pressure in the inner cavity of the steam generator greater than the air pressure in the inner cavity of the water replenishing tank. Due to the high air pressure in the inner cavity of the steam generator, the cold water in the water replenishing tank cannot enter the steam generator, resulting in abnormal operation of the steam generator and the water replenishing tank. If the ventilation pipe is set, the excess gas in the steam generator will enter the water replenishing tank along the ventilation pipe to balance the air pressure between the steam generator and the water replenishing tank.

[0020] The water level sensor is arranged on the water replenishing tank separated from the steam generator, and the structure of arranging the water level sensor in the steam generator is cancelled, effectively avoiding excessive scale adhesion on the water level sensor, and further avoiding affecting the detection accuracy of the water level sensor.

[0021] The water level position height in the water replenishing tank is detected by the water level sensor. When the water level in the water replenishing tank is too low, water enters. When the water level in the water replenishing tank is too high, the water replenishing tank does not supply water, so that the water replenishing tank cannot supply water to the steam generator.

[0022] The water level sensor is electrically connected to the control module through the first wire. Switch valves are arranged on the cold water channels between the steam generator, the water replenishing tank, and the water inlet device. The switch valves are electrically connected to the control module through the second wire. The water level sensor detects the water level condition of the water replenishing tank and feeds it back to the control module. The control module acts on the switch valves through the detection signal of the water level sensor to open and close the switch valves, and then open and close the cold water channels between the steam generator, the water replenishing tank, and the water inlet device.

[0023] A sewage outlet is provided on the steam generator to discharge the sewage in the steam generator. A steam outlet is provided on the top of the steam generator, and the steam outlet is directly or indirectly connected to one end of the conveying pipe structure.

[0024] When the steam outlet is indirectly connected to the conveying pipe structure, a tee joint is provided between the steam outlet and the conveying pipe structure. The first end of the tee joint is connected to the conveying pipe structure, the second end of the tee joint is connected to the steam outlet, and a safety exhaust valve is provided on the third end of the tee joint to discharge the excess steam.

[0025] A cover body for blocking water vapor is provided in the steam generator corresponding to the steam output end. The top of the cover body covers the steam output end and is connected to the steam output end. A diversion wall for returning water vapor is provided on the inner side of the cover body, and the diversion wall is arranged in an arc shape or an inclined plane. The cover body is provided with an air outlet communicating with the air outlet end of the steam generator. The inner diameter of the inner cavity of the cover body gradually decreases towards the air outlet end of the steam generator. The cover body plays a role in blocking liquid. When the liquid (water vapor) reaches the cover body, due to the gradual decrease of the inner diameter of the inner cavity of the cover body towards the air outlet end of the steam generator, the liquid (water vapor) falls back to the bottom of the inner cavity of the steam generator under the blocking action of the cover body.

[0026] A heating element is provided at the bottom of the steam generator. An electronic NTC temperature sensor and a mechanical snap-action thermostat are also provided at the bottom of the steam generator to prevent the steam generator from dry burning.

[0027] The beneficial effects of the present utility model are as follows:

[0028] The one-way valve is arranged on the vertical section. The liquid entering the vertical section flows back into the machine body under the action of gravity, ensuring that the steam delivery pipe structure will not cause blockage.

[0029] The water level sensor is arranged on the water replenishing tank separated from the steam generator, and the structure of arranging the water level sensor in the steam generator is cancelled. Since only cold water enters the water replenishing tank, it effectively avoids excessive scale adhesion on the water level sensor, thereby avoiding affecting the detection accuracy of the water level sensor.
