Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ammonia water transportation technology, and in particular relates to an ammonia water transportation anti-blocking device. Background Technology
[0002] Ammonia water is an aqueous solution of gaseous ammonia, with NH3·H2O as its main component, i.e., ammonia monohydrate. It is colorless, transparent, and has a pungent odor. Ammonia water is less dense than water, unstable, volatile, and easily decomposes when exposed to light or heat. Ammonia water itself is a non-flammable and non-explosive liquid. However, the ammonia gas separated from the water has a strong, pungent odor and is irritating and corrosive to the eyes, nose, and skin, and also poses a risk of combustion and explosion.
[0003] In the widespread use of ammonia water, a concentration of 20% is generally used. The problem is that in northern winters, temperatures are low, and the freezing point of 20% ammonia water is -35℃. During production, the ammonia water in the pipelines frequently freezes and becomes blocked, affecting production. To avoid this, an ammonia water conveying anti-blockage device is provided. Utility Model Content
[0004] This invention provides an anti-clogging device for ammonia water transportation, aiming to solve the problem that in the use of ammonia water, generally with a concentration of 20%, the low winter temperatures in northern regions mean that 20% ammonia water has a freezing point of -35℃. This often leads to low-temperature solidification and blockage of the ammonia water pipeline during production, affecting production.
[0005] This utility model is implemented as follows: an ammonia water conveying anti-clogging device includes an upper base and a conveying pipe: a cleaning component is fixedly connected to the top of the upper base, and a heating component is fixedly connected to the top of the upper base.
[0006] The cleaning assembly includes an upper bracket fixedly mounted on an upper base and an inner cleaning ring frame fitted against the inner wall of the conveying pipe. One end of the upper bracket is fixedly connected to a telescopic hydraulic cylinder, and one end of the telescopic hydraulic cylinder is fixedly connected to an outer magnetic frame. Through the arrangement of the cleaning assembly, during use, the telescopic hydraulic cylinder can be activated and controlled to move the outer magnetic frame back and forth on the upper conveying pipe. The mutual attraction between the outer magnetic frame and the inner cleaning ring frame allows the outer magnetic frame to attract the inner cleaning ring frame to slide along the inner wall, thereby scraping and breaking ice from the inner wall of the conveying pipe, ensuring normal conveying.
[0007] The temperature-raising component includes a straight-tube fan, a temperature-raising base, and an upper ring plate. The temperature-raising base includes an annular base, with a first heating resistance wire embedded in the inner wall of the annular base. The annular base has edges on both sides, and inclined air vents are opened on the outer walls of the edges. A second heating resistance wire is embedded around the inclined air vents. Through the configuration of the temperature-raising component, and in conjunction with a gas thermometer installed at the bottom of the delivery pipe, when the gas thermometer senses that the internal temperature of the delivery pipe reaches approximately -35°C, the first and second heating resistance wires are activated. The fan speed is also activated and controlled, causing the heat generated by the first and second heating resistance wires to be discharged upwards through the straight-tube fan to the bottom of the upper ring plate. This heat is then used to raise the temperature of the bottom through the delivery pipe, preventing ammonia from solidifying in the delivery pipe and thus achieving an internal anti-clogging effect.
[0008] Preferably, the inner wall of the outer magnetic frame is fitted and connected to the outer wall of the conveying pipe, and a strong magnetic block is provided inside the inner cleaning ring frame.
[0009] Preferably, two wind-blocking side plates are fixedly connected to both sides of the upper ring plate; by setting the two wind-blocking side plates, a better limiting effect on the airflow can be achieved, so that the airflow flows to both sides of the downward conveying pipe, improving the heat utilization rate of the airflow.
[0010] Preferably, the outer wall of the annular base is fixedly connected with several connecting brackets, and one end of the connecting bracket is fixedly connected to the outer wall of the upper ring plate.
[0011] Preferably, the bottom of the straight-tube fan is fixedly connected to a corner bracket, and the bottom of the corner bracket is fixedly connected to the outer wall of the upper base.
[0012] Preferably, when the conveying pipe is in a horizontal position, several thermometers are equidistantly arranged on the bottom side, and the thermometers are gas thermometers.
[0013] Preferably, the lower base is fitted to the bottom inner wall of the upper base, and a lifting hydraulic cylinder is provided between the upper base and the lower base. The number of lifting hydraulic cylinders is multiple. By setting up the lifting hydraulic cylinder and using it in conjunction with the upper base and the lower base, the height of the device can be adjusted, thereby achieving a better working effect with the conveying pipe.
[0014] Compared with the prior art, the embodiments of this application have the following main advantages:
[0015] By setting up the cleaning components, during use, the telescopic hydraulic cylinder can be used to drive the outer magnetic frame to move back and forth on the upper conveying pipe through starting and control. The outer magnetic frame and the inner cleaning ring frame attract each other, thereby attracting the inner cleaning ring frame to slide along the inner wall, thus scraping and breaking ice on the inner wall of the conveying pipe, thereby ensuring the normal conveying of the conveying pipe.
[0016] By setting up the heating component and cooperating with the gas thermometer installed at the bottom of the delivery pipe, when the gas thermometer senses that the internal temperature of the delivery pipe reaches about -35℃, the first heating resistance wire and the second heating resistance wire are activated, and the wind speed of the straight-tube fan is started and controlled. The heat generated by the first heating resistance wire and the second heating resistance wire is discharged upward to the bottom of the upper ring plate by the air of the straight-tube fan, and the bottom is heated through the delivery pipe to prevent the ammonia water from solidifying in the delivery pipe, thereby achieving an internal anti-blocking effect on the delivery pipe.

[0024] This utility model embodiment provides an ammonia water conveying anti-blockage device, such as... Figure 1-4 As shown, it includes an upper base 4 and a conveying pipe 1: a cleaning component 2 is fixedly connected to the top of the upper base 4, and a heating component 3 is fixedly connected to the top of the upper base 4.
[0025] The cleaning component 2 includes an upper bracket 201 fixedly mounted on the upper base 4 and an inner cleaning ring frame 204 fitted to the inner wall of the conveying pipe 1. One end of the upper bracket 201 is fixedly connected to a telescopic hydraulic cylinder 202, and one end of the telescopic hydraulic cylinder 202 is fixedly connected to an outer magnetic frame 203.
[0026] The inner wall of the outer magnetic frame 203 is fitted and connected to the outer wall of the conveying pipe 1, and a strong magnetic block is provided inside the inner cleaning ring frame 204.
[0027] It should be noted that, in most cases of ammonia water use, a 20% concentration is typically used. The problem is that in northern winters, temperatures are low, and the freezing point of 20% ammonia water is -35℃. This often leads to low-temperature solidification and blockage of the ammonia water pipelines during production, affecting operations.
[0028] Specifically, in this embodiment, the solution mainly uses the upper base 4, conveying pipe 1, base 4, cleaning component 2 and temperature raising component 3. In use, the conveying pipe 1 is connected to the ammonia water conveying system, and other mechanisms are installed. The temperature raising component 3 works with a gas thermometer. When the gas thermometer senses that the internal temperature of the conveying pipe 1 reaches about -35°C, the first heating resistance wire 3032 and the second heating resistance wire 3034 are activated, and the wind speed of the straight-tube fan 304 is started and controlled. The heat generated by the first heating resistance wire 3032 and the second heating resistance wire 3034 is discharged upward to the bottom of the upper ring plate 301 through the air of the straight-tube fan 304. The bottom is heated through the conveying pipe 1 to prevent the ammonia water from solidifying in the conveying pipe 1, thereby achieving an internal anti-blocking effect on the conveying pipe 1.
[0029] At the same time, by starting and controlling the telescopic hydraulic cylinder 202, the outer magnetic frame 203 is driven to move back and forth in the upper conveying pipe 1. The outer magnetic frame 203 and the inner cleaning ring frame 204 attract each other, thereby attracting the inner cleaning ring frame 204 to slide along the inner wall, thereby scraping and breaking ice on the inner wall of the conveying pipe 1, thus ensuring the normal conveying of the conveying pipe 1.
[0030] In this embodiment, by setting up the cleaning component 2, during use, the telescopic hydraulic cylinder 202 can be activated and controlled to drive the outer magnetic frame 203 to move back and forth on the upper conveying pipe 1. The outer magnetic frame 203 and the inner cleaning ring frame 204 attract each other, thereby attracting the inner cleaning ring frame 204 to slide along the inner wall, thereby scraping and breaking ice on the inner wall of the conveying pipe 1, thus ensuring the normal conveying of the conveying pipe 1.
[0031] In a further preferred embodiment of this utility model, such as Figure 1-4 As shown, the heating component 3 includes a straight-tube fan 304, a heating base 303, and an upper ring plate 301. The heating base 303 includes an annular base 3031. A first heating resistance wire 3032 is embedded in the inner wall of the annular base 3031. Edges are provided on both sides of the annular base 3031, and an inclined air outlet 3033 is opened on the outer wall of the edge. A second heating resistance wire 3034 is embedded around the inclined air outlet 3033.
[0032] Two windproof side plates 302 are fixedly connected to both sides of the upper ring plate 301;
[0033] Several connecting brackets are fixedly connected to the outer wall of the annular base 3031, and one end of the connecting bracket is fixedly connected to the outer wall of the upper ring plate 301.
[0034] The bottom of the straight-tube fan 304 is fixedly connected to an angle bracket, and the bottom of the angle bracket is fixedly connected to the outer wall of the upper base 4;
[0035] Several thermometers, which are gas thermometers, are equidistantly arranged on the bottom side of the conveying pipe 1 when it is in a horizontal position.
[0036] In this embodiment, by setting the heating component 3 and cooperating with the gas thermometer set at the bottom of the conveying pipe 1, when the gas thermometer senses that the internal temperature of the conveying pipe 1 reaches about -35°C, the first heating resistance wire 3032 and the second heating resistance wire 3034 are activated, and the wind speed of the straight-tube fan 304 is started and controlled. The heat generated by the first heating resistance wire 3032 and the second heating resistance wire 3034 is discharged upward to the bottom of the upper ring plate 301 through the air of the straight-tube fan 304, and the bottom is heated through the conveying pipe 1 to prevent the ammonia water from solidifying in the conveying pipe 1, thereby achieving an internal anti-blocking effect on the conveying pipe 1.
[0037] In this embodiment, the two windproof side plates 302 can achieve a better limiting effect on the airflow, thereby improving the heat utilization rate of the airflow as it flows downward to both sides of the conveying pipe 1.
[0038] In a further preferred embodiment of this utility model, such as Figure 1-4 As shown, the lower base 6 is attached to the bottom inner wall of the upper base 4, and a lifting hydraulic cylinder 5 is provided between the upper base 4 and the lower base 6.
