Description

Technical Field

[0001] The invention relates to the technical field of temperature control equipment, in particular to a temperature control equipment for water-soluble fertilizer fermentation. Background Art

[0002] Water-soluble fertilizer is a kind of fertilizer composed of various elements. It needs to be fermented during the production process. In addition, the fermentation temperature of water-soluble fertilizer is also very high. Therefore, it is necessary to control the temperature of water-soluble fertilizer during fermentation, which determines the quality of water-soluble fertilizer after production.

[0003] For example, the invention patent with Chinese patent application number: CN202310590184.0 discloses a water-soluble fertilizer fermentation temperature control device, including a fermentation barrel and a base, support rods are respectively installed at the front and rear ends of the top surface of the base, and a rotatable turntable is installed at the opposite ends of the two support rods. The fermentation barrel is located between the two turntables and is connected to the turntables. A first through hole is opened on the top of one side of the fermentation barrel, and multiple effects can be achieved through one operation, and the effect is better during use. When cooling is not required, the fermentation barrel is driven to rotate by the turntable. At this time, the opening and closing mechanisms in the first through hole and the second through hole are in a closed state, so that the water-soluble fertilizer can flow in the fermentation barrel, the water-soluble fertilizer can be mixed, and the materials are mixed more evenly. Different operations can be selected according to different needs to achieve different effects.

[0004] Although the above device can make the water-soluble fertilizer heated evenly during fermentation, and can automatically ventilate and cool down after the temperature of the water-soluble fertilizer increases due to the heating device; however, only after the first through hole or the second through hole is opened, the air naturally flows in the fermentation barrel, and the efficiency of cooling the water-soluble fertilizer by ventilation is poor. It must be continued for a long time before the temperature of the water-soluble fertilizer in the fermentation barrel can be reduced, which is not conducive to the fermentation of the water-soluble fertilizer and reduces the production efficiency of the water-soluble fertilizer. Summary of the invention

[0005] The invention discloses a temperature control device for water-soluble fertilizer fermentation, which solves the problem that the water-soluble fertilizer has a poor cooling efficiency in a method of ventilation through the natural flow of air in a fermentation barrel, and a long time must be maintained to reduce the temperature of the water-soluble fertilizer in the fermentation barrel, thereby reducing the production efficiency of the water-soluble fertilizer.

[0006] In order to solve the above technical problems, the present invention specifically adopts the following technical solutions:

[0007] A temperature control device for water-soluble fertilizer fermentation comprises a base, a support frame is fixed on the top of the base, a fermentation barrel is rotatably connected to the inner side of the support frame, a No. 1 motor for driving the fermentation barrel is provided on the support frame, and an electric heating tube is fixed in the fermentation barrel; a sealing plate is fixed on the top of the fermentation barrel, two left-right symmetrical connecting pipes are provided in the fermentation barrel, opposite surfaces of the two connecting pipes are connected with a group of one-way valves, and a fan for exhausting air to the two connecting pipes is provided on the sealing plate; exhaust pipes are connected to both sides of the fermentation barrel, the two exhaust pipes are staggered up and down, one end of the exhaust pipe away from the fermentation barrel is connected with a fixed pipe with an inner diameter larger than the exhaust pipe, a sealing block for sealing the exhaust pipe is provided in the fixed pipe, a temperature detection sensor is inlaid on a side of the sealing block close to the fermentation barrel, an electric telescopic rod for driving the sealing block away from the exhaust pipe is provided on the fixed pipe, and an air supply pipe is connected to the fixed pipe.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] During the fermentation of water-soluble fertilizer in the fermentation barrel, the electric heating tube can be started to heat the water-soluble fertilizer. When the temperature detection sensor detects that the temperature exceeds the set temperature, the No. 1 motor drives the fermentation barrel to rotate clockwise first to tilt the fermentation barrel so that the exhaust pipe on the top is located above the fermentation barrel, and the water-soluble fertilizer in the fermentation barrel is away from the exhaust pipe, and the electric telescopic rod on the fixed pipe connected to it drives the sealing block away from the exhaust pipe, and the exhaust pipe is no longer sealed; at the same time, after the fan is started to transport cold air to the two connecting pipes, the connecting pipe close to the exhaust pipe that is opened at this time and located on the water-soluble The one-way valve outside the water-soluble fertilizer can exhaust the wind into the fermentation barrel, speeding up the circulation of air in the fermentation barrel, so that the air can enter the fixed pipe through the opened exhaust pipe, and then be discharged through the air supply pipe to complete the ventilation in the fermentation barrel; when the fermentation barrel is rotated from a vertical state to a horizontal state, a group of one-way valves on the connecting pipe close to the opened exhaust pipe are all located outside the water-soluble fertilizer, and the exhausted wind can further speed up the cooling operation of the water-soluble fertilizer in the fermentation barrel, and then the No. 1 motor drives the fermentation barrel to rotate counterclockwise until the fermentation barrel is restored, and the sealing block is restored to continue to seal the exhaust pipe, and the fan is closed at the same time; and the No. 1 motor drives the fermentation barrel to rotate counterclockwise until the fermentation barrel is restored. Then the sealing block is restored to continue to seal the exhaust pipe, and the fan is closed at the same time; Motor No. 1 continues to drive the fermentation barrel to rotate counterclockwise (rotate 90°), so that the exhaust pipe at the bottom is located above the fermentation barrel, and the electric telescopic rod on the fixed pipe connected to it drives the sealing block to move away from the exhaust pipe, and no longer seals the exhaust pipe. The fan starts, and the wind continues to be transported into the connecting pipe. The one-way valve on the connecting pipe close to the opened exhaust pipe can discharge the wind into the fermentation barrel to continue to cool the water-soluble fertilizer. When the fermentation barrel continues to rotate until the fermentation barrel is in a vertical state, motor No. 1 drives the fermentation barrel to rotate clockwise. When the fermentation barrel changes from a vertical state to a horizontal state, , the corresponding sealing block is restored to continue to seal the exhaust pipe, and the fan is turned off; subsequently, the fermentation barrel is rotated clockwise and counterclockwise according to the above operation to cool the water-soluble fertilizer in the fermentation barrel, and when the fermentation barrel is rotated, the water-soluble fertilizer can flow in the fermentation barrel to promote the mixing of the water-soluble fertilizer, and at the same time, the water-soluble fertilizer can be prevented from being heated unevenly due to being stationary; the present invention can effectively improve the cooling efficiency of the water-soluble fertilizer, make the cooling effect of the water-soluble fertilizer obvious, ensure that the water-soluble fertilizer can be fully fermented at a suitable temperature, and improve the production efficiency and quality of the water-soluble fertilizer.

[0019] like Figure 1 and Figure 2As shown, a water storage shell 8 is fixed to the bottom of the fermentation barrel 3, and the top of the water storage shell 8 is connected to a short tube 81 that passes through the bottom of the fermentation barrel 3.

The annular shell 82 is located between the two connecting tubes 32; the electric heating tube 38 is located on the inner side of the annular shell 82, and the bottom of the fermentation barrel 3 is connected to a feed pipe 35 that passes through the water storage shell 8, and the bottom of the water storage shell 8 is connected to a drain pipe 84, and one side of the water storage shell 8 is connected to a water injection pipe 85. The top and bottom of the fermentation barrel 3 can be swapped first, and the water-soluble fertilizer can be transported to the fermentation barrel 3 through the feed pipe 35, and then the fermentation barrel 3 can be restored; then hot water is injected into the water storage shell 8 through the water injection pipe 85, and then the No. 1 motor 21 is started to drive the fermentation barrel 3 to rotate repeatedly clockwise and counterclockwise, and the hot water in the water storage shell 8 can enter the annular shell 82 through the short tube 81, and the hot water in the annular shell 82 can enter a group of inclined tubes 83, and cooperate with the electric heating tube 38 to quickly heat the water-soluble fertilizer; subsequently, when the hot water in the water storage shell 8 is cooled and becomes cold water (cold water can also be added to the water storage shell 8), when the water-soluble fertilizer needs to be cooled, when the fermentation barrel 3 is repeatedly rotated clockwise and counterclockwise, the cold water can also enter the inclined tube 83, thereby accelerating the cooling efficiency of the water-soluble fertilizer; the scraper 34 is arranged in an L shape, and the annular shell 82 is located between the two scrapers 34; the water in the water storage shell 8 can be discharged through the drain pipe 84.

[0020] like Figure 1 and Figure 3 As shown, the support frame 2 is set in a U shape, the main body of the No. 1 motor 21 is fixed to one side of the support frame 2 through a bearing block, and a rotating rod 22 that penetrates the support frame 2 and is fixed to the fermentation barrel 3 is fixed on the rotating shaft of the No. 1 motor 21; a battery 7 is fixed on the top of the sealing plate 31. After starting the No. 1 motor 21, the fermentation barrel 3 can be driven to rotate through the rotating rod 22, and the battery 7 can supply power to the electric heating tube 38, the electric telescopic rod 63, the temperature detection sensor on the sealing block 62, the fan 4, the solenoid valve 42 and the No. 2 motor 51, and a control panel is fixed on the sealing plate 31 (the control panel is not shown in the figure), so that after the staff sets the program, when the temperature detection sensor detects that the temperature of the water-soluble fertilizer has increased, the control panel controls the opening and closing of the No. 1 motor 21, the fan 4, the No. 2 motor 51 and the two electric telescopic rods 63.

[0021] like Figure 1 As shown, the base 1 is hollow, the top of the base 1 is connected with a folding tube 9, the top of the folding tube 9 is fixed with a connector 91, and the top of the connector 91 is rotatably connected with a sleeve 92 adapted to the drain pipe 84. After the folding tube 9 is stretched upward, the sleeve 92 is connected to the bottom of the drain pipe 84, and the water in the water storage shell 8 is drained into the base 1.

[0022] like Figure 1 and Figure 3 As shown, the fermentation barrel 3 is fixed with a fixed cylinder 36 that penetrates the side of the support frame 2 away from the first motor 21, and the fixed cylinder 36 is rotatably connected to the support frame 2. Two air pipes 64 are respectively connected to the fixed cylinder 36 located on the inner side of the support frame 2; the fixed cylinder 36 is rotatably connected to the end away from the fermentation barrel 3 with a delivery pipe 37, and the bottom end of the delivery pipe 37 penetrates the top of the base 1 and is close to the bottom surface of the base 1; the top of the base 1 is connected with an outlet pipe 11. When the fan 4 is started to cool the water-soluble fertilizer, the air entering the fixed pipe 61 through the exhaust pipe 6 in the fermentation barrel 3 has a peculiar smell. In order to prevent the peculiar smell from affecting the environment in the workshop, the air entering the fixed pipe 61 can be transported to the fixed cylinder 36 through the air pipe 64, and then transported to the water in the base 1 through the delivery pipe 37 to purify the air, and filter cotton can also be set at the top of the base 1 to further purify the air with peculiar smell, so that when the air is discharged through the outlet pipe 11, it will not cause a great impact on the environment in the workshop.

[0023] When in use, when the temperature detection sensor on the sealing block 62 detects that the temperature of the water-soluble fertilizer in the fermentation barrel 3 exceeds the set value and the water-soluble fertilizer in the fermentation barrel 3 needs to be cooled, the first motor 21 starts to drive the fermentation barrel 3 to start rotating clockwise (for ease of description, the first motor 21 is used as the first motor 21). Figure 1 In the orientation shown in the figure, the exhaust pipe 6 located on the upper left side of the fermentation barrel 3 is subsequently described as exhaust pipe A 6, and the corresponding other exhaust pipe 6 is described as exhaust pipe B 6); when the fermentation barrel 3 starts to rotate clockwise, the water-soluble fertilizer in the fermentation barrel 3 moves away from the exhaust pipe A 6, at this time, the fan 4 is turned on, and the electric telescopic rod 63 on the fixed pipe 61 connected to the exhaust pipe A 6 is started, so that the sealing block 62 no longer seals the exhaust pipe A 6, and the cold air input into the two connecting pipes 32 by the fan 4 can be discharged through the one-way valve 33 located outside the water-soluble fertilizer, thereby accelerating the circulation of air in the fermentation barrel 3 and quickly cooling the water-soluble fertilizer. The air in the fermentation barrel 3 enters the fixed pipe 61 and is discharged through the air supply pipe 64; when the fermentation barrel 3 rotates clockwise 9 When it continues to rotate after 0°, the sealing block 62 is restored to seal the A exhaust pipe 6, and the fan 4 is turned off. As the fermentation barrel 3 rotates (after the fermentation barrel 3 continues to rotate 90°), the B exhaust pipe 6 exchanges positions with the A exhaust pipe 6. At this time, the fermentation barrel 3 continues to rotate, and the electric telescopic rod 63 on the fixed pipe 61 connected to the B exhaust pipe 6 is started, so that the sealing block 62 no longer seals the B exhaust pipe 6, and the fan 4 is turned on to continue to cool the water-soluble fertilizer in the fermentation barrel 3; the above operation is repeated subsequently, by alternately opening the A exhaust pipe 6 and the B exhaust pipe 6, and by the continuous rotation of the fermentation barrel 3, the water-soluble fertilizer can be repeatedly flowed in the fermentation barrel 3, and the water-soluble fertilizer can be mixed, thereby improving the overall cooling efficiency and effect of the water-soluble fertilizer.

[0024] When the fermentation tank 3 is in a vertical position (such as Figure 1 ), the water-soluble fertilizer is away from the exhaust pipe A 6, and the fermentation barrel 3 can be turned on and off during the process of rotating 90° clockwise by 90°, and the fan 4 and the exhaust pipe A 6 are turned on. After the wind is discharged through the one-way valve 33 outside the water-soluble fertilizer on the connecting pipe 32, the water-soluble fertilizer can be cooled. Then, after the fermentation barrel 3 is restored by rotating 90° counterclockwise, the fan 4 and the exhaust pipe A 6 are closed; after the fermentation barrel 3 is rotated 90° counterclockwise again, the water-soluble fertilizer is away from the exhaust pipe B 6, the exhaust pipe B 6 and the fan 4 are turned on, and the water-soluble fertilizer is continued to be cooled by blowing, and the fermentation barrel 3 continues to rotate 90° counterclockwise. After the fermentation barrel 3 is rotated 90° clockwise again, the fan 4 and the exhaust pipe B 6 are closed; subsequently, the fermentation barrel 3 continues to repeat the above operation of repeatedly rotating forward and reverse, so that the water-soluble fertilizer in the fermentation barrel 3 is repeatedly mixed and circulated, so as to improve the cooling efficiency of the water-soluble fertilizer; and when the water-soluble fertilizer does not need to be cooled, the fermentation barrel 3 can also be repeatedly rotated to improve the mixing efficiency of the water-soluble fertilizer.
