Description

Technical Field

[0001] The present invention relates to the technical field of compound fertilizer processing, and specifically to a heating and stirring device for the production of compound fertilizers. Background Art

[0002] At present, compound fertilizers refer to chemical fertilizers containing two or more main nutrient elements. Compared with single-element fertilizers, compound fertilizers have the advantages of high nutrient content, few by-products, and good physical properties, and play a very important role in balanced fertilization, improving fertilizer utilization rate, and promoting high and stable yields of crops. During the fertilizer production process, it is necessary to heat and stir the raw materials;

[0003] The inventor found that: a fertilizer stirring device for compound fertilizer production disclosed in a Chinese patent with publication number CN112516869A includes a bottom plate. Four support columns are fixedly connected to the upper wall of the bottom plate. The upper ends of the four support columns are jointly fixedly connected to a stirring box. A feeding pipe is communicated with the upper wall of the stirring box. A discharge pipe is communicated with the lower wall of the stirring box. A solenoid valve is provided on the discharge pipe. A stirring mechanism is provided on the stirring box. The structure of the present invention is reasonably designed, and it can stir the materials from multiple directions, making the materials move more violently in the stirring box, improving the stirring effect of the device on the materials, and also making the fertilizer solution at the bottom turn over up and down, so that the fertilizer solution is evenly mixed, and the stirring box can be heated to prevent the occurrence of fertilizer caking caused by the reduction of temperature during the stirring process.

[0004] And a Chinese patent with bulletin number CN117753027B discloses a high-efficiency evaporation and concentration device for traditional Chinese medicine preparations, which relates to the technical field of traditional Chinese medicine processing, including a processing frame. A connecting pipe is installed at the top of the processing frame through bolts, and a condensing mechanism. The condensing mechanism includes a heat exchange frame and a heat exchanger. The heat exchange frame is installed at the upper right end of the processing frame through bolts. The heat exchanger is installed at the upper right end of the top of the heat exchange frame through bolts. One end of the connecting pipe away from the processing frame is connected to the upper left side of the top of the heat exchange frame through bolts. When heating, evaporating, and separating the liquid medicine in the inner cavity of the processing frame in the present invention, the heating and mixing mechanism is started to make the hot air flow contact the liquid medicine in the inner cavity of the processing frame, heat and evaporate and separate the liquid medicine, so that the liquid and solid substances in the liquid medicine are separated. The evaporation and separation are carried out by heating the air, which is faster and avoids the situation of dead corners during the heating and separation process.

[0005] The prior art only solves the problems that the stirring method is too single, resulting in the phenomenon that some fertilizers are prone to caking, thus reducing the product quality, and the situation that the processing is not sufficient and dead corners appear during the concentration process;

[0006] However, during the processing, the integral method of using stirring blades is adopted for processing. As a result, the processing frequency is not high enough. During the processing, the raw materials cannot be crushed. If caking occurs, the caked raw materials cannot be processed. Moreover, the heating or cooling working mode cannot be adjusted according to the temperature during processing, and the moisture generated during heating or cooling cannot be separated and absorbed, thus unable to ensure the stability during processing.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. During the process of processing raw materials, the present invention forms a number of small counterclockwise stirring areas around the inner cavity of the processing frame, and the stirring areas also move inside the processing frame. By forming a clockwise stirring area in the middle of the inner cavity of the processing frame, the counterclockwise stirring area contacts the clockwise stirring area, making the processing of raw materials more efficient and sufficient. In addition, an inclined structure is provided outside the stirring end of the reverse stirring area, so that the raw materials can be pushed upward during processing, and the inner periphery of the processing frame can be treated during processing to prevent raw materials from adhering to the periphery of the processing frame. Moreover, the raw materials can be subjected to extrusion and crushing treatment during the stirring process. Even if agglomeration occurs during the processing, the agglomerated raw materials can be processed.

[0020] 2. During the process of processing raw materials, the present invention can cool and heat the raw materials according to the requirements during the processing of the raw materials. During the cooling and heating processes, the raw materials during processing are monitored in real time, and according to the monitoring results, the processing temperature and the processing method are adjusted. By allowing the air flow to flow inside the processing frame and contact the raw materials, the raw materials are turned over around the inner cavity of the processing frame, improving the efficiency of processing the raw materials. In addition, by allowing the air flow to contact the raw materials from bottom to top, the agglomerated raw materials are dispersed, preventing the temperature required for processing the raw materials from being regulated in a timely and effective manner during the processing, which may lead to abnormal raw materials and failure to meet the standards during subsequent production.

[0021] 3. During the cooling process of the present invention, the water vapor generated by cooling can be adsorbed, ensuring the dryness of the air flow during transportation, increasing the smoothness of the air flow during the flow process, and improving the protection ability of the transmission mechanism during operation. This can prevent the air flow generated during the flowing cooling process from not being processed, resulting in the water vapor remaining inside the air flow all the time. As time goes by, with the increase of water vapor, it will not only affect the flow rate of the air flow, but also cause the water vapor to come into contact with the rotating mechanism, affecting the normal rotation of the rotating mechanism. Over time, it will also cause the problem of rust on the rotating mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The stirring mechanism 4 further includes a single-phase motor 401, a rotating wheel 402, a rotating belt 403, a rotating rod 406, a processing plate 407 and an elastic strip plate 408. A circular opening is formed in the middle of the fixed gear 404. The single-phase motor 401 is installed at the upper end of the inner cavity of the fixed frame 3 through a mounting seat. The rotating rod 406 is movably installed in the middle of the inner cavity of the processing frame 1. A rotating hole is opened in the middle of the top end of the processing frame 1. The top end of the rotating rod 406 passes through the circular opening and the rotating hole and is connected to the output end of the single-phase motor 401. The rotating rod 406 does not contact the inside of the circular opening. A number of connecting frame rods are installed between the top end around the fixed gear 404 and the top end of the inner cavity of the processing frame 1. The rotating wheel 402 is movably installed at the upper end of the rotating rod 406 and at one side of the top end of the inner cavity of the mounting long frame 2. Two connecting through holes are opened at the bottom right end of the fixed frame 3. The rotating belt 403 is sleeved and installed between the outer parts of the two rotating wheels 402. A number of processing plates 407 are equidistantly installed around the middle of the rotating rod 406, and the elastic strip plate 408 is installed on one side of the processing plate 407 away from the rotating rod 406;

[0037] The stirring mechanism 4 further includes a stirring frame 409, a movable rod 410, a bottom arc plate 411, a connecting rod 412, a protective cover 413, a rotating gear 414 and a transmission gear 415. Installation holes are formed around the multi-angle turntable 405. Connecting rods 412 are installed around the multi-angle turntable 405 at relative positions of the installation holes through bearings.

The rotating gear 414 meshes with the bottom transmission gear 415. A movable rod 410 is installed at the bottom end of the rotating gear 414. Stirring frames 409 are installed at one side of the bottom end of the movable rod 410. The stirring frame 409 includes a round rod and stirring strip plates, and the stirring strip plates installed around the round rod are distributed obliquely. The top end of the round rod is connected to one side of the bottom end of the movable rod 410. A protective cover 413 is installed between the outside of the rotating gear 414 and the bottom transmission gear 415 around the bottom of the multi-angle turntable 405. A circular opening is formed at one side of the bottom end of the protective cover 413. The middle of the multi-angle turntable 405 is connected to the rotating rod 406;

[0038] The specific implementation method is as follows: When performing the stirring operation, start the single-phase motor 401 to drive the rotating rod 406 to rotate, drive the left rotating wheel 402 to rotate through the rotating rod 406, drive the right rotating wheel 402 to rotate through the rotating belt 403. When the rotating rod 406 rotates, drive the multi-angle turntable 405 to rotate, drive the surrounding transmission gears 415 to rotate through the connecting rod 412. Since the top transmission gear 415 meshes with the fixed gear 404 and the fixed gear 404 does not rotate, the top transmission gear 415 rotates outside the fixed gear 404, drive the bottom transmission gear 415 to rotate through the connecting rod 412, and drive the rotating gear 414 to rotate. Then drive the surrounding stirring frames 409 to rotate counterclockwise through the movable rod 410. Through the surrounding stirring frames 409, and the rotating rod 406 drives the surrounding processing plates 407 to rotate clockwise. Then several stirring areas are formed around the inner cavity of the processing frame 1, and the stirring areas also move inside the processing frame 1. When the processing plate 407 moves, drive the elastic strip plate 408 to move, so that the elastic strip plate 408 contacts the outside of the stirring frame 409, and the elastic strip plate 408 deforms. When the stirring frame 409 continues to move, separate the stirring frame 409 from the elastic strip plate 408. Through the collision, the stirring frame 409 can generate vibration, and shake off the raw materials attached to the outside of the stirring frame 409.

[0039] Around the top of the multi-angle turntable 405, an annular mounting plate 13 is installed. Around the top of the inner cavity of the processing frame 1, a mounting ring rail 9 is installed. Inside the mounting ring rail 9, a mounting ring strip 10 is slidably installed. Around the bottom of the mounting ring strip 10, a number of docking notches 11 are equidistantly opened. At the relative positions of the docking notches 11 around the top of the annular mounting plate 13, docking bumps 12 are installed. At the top of the inner cavity of the docking bump 12 and the top of the inner cavity of the docking notch 11, docking magnets 14 are installed. Around the top and bottom of the inner cavity of the processing frame 1, a number of temperature controllers 16 are installed. At the bottom of the front side of the processing frame 1, a control panel is installed. The single-phase motor 401 and the temperature controllers 16 are electrically connected to the control panel;

[0040] The specific implementation method is as follows: When the multi-angle turntable 405 rotates, it drives the annular mounting plate 13 to rotate. Through the cooperation of the docking bump 12 and the docking notch 11, it drives the mounting ring strip 10 to slide inside the mounting ring rail 9, increasing the stability and flexibility of the multi-angle turntable 405 during rotation, and the protective effect of the annular mounting plate 13 to prevent raw materials from running to the transmission connection, affecting the normal operation of the transmission mechanism.

[0041] The device further includes a processing mechanism 5.

At the bottom of the rotating rod 406, a multi-angle connecting frame is installed. Around the bottom of the multi-angle connecting frame, a bottom arc plate 411 is installed. Around the top of the multi-angle connecting frame, an arc-shaped long plate is installed. Movable notches 503 are opened around the multi-angle turntable 405 and the multi-angle connecting frame. On one side of the inner cavity of the movable notch 503, a moving slider 505 is slidably installed. On the opposite side of the four moving sliders 505, a moving ejector rod 507 is installed. On the side of the moving slider 505 away from the moving ejector rod 507, a compression spring 504 is installed. Around the inner cavity of the processing frame 1, movable scraping bars 502 are arranged. The end of the moving ejector rod 507 away from the moving slider 505 is connected to the movable scraping bar 502.

Around the inner cavity of the processing frame 1, blocking inclined bars 501 are installed. On the side of the movable scraping bar 502 close to the blocking inclined bar 501, inclined surfaces are opened;

[0042] The specific implementation method is as follows: When the multi-angle turntable 405 and the multi-angle connecting frame rotate, they drive the moving ejector rods 507 around to rotate. The moving ejector rods 507 drive the movable scraping strips 502 around to rotate. The movable scraping strips 502 scrape the inner periphery of the processing frame 1. When the inclined surface of the movable scraping strip 502 contacts the inclined surface of the blocking inclined strip 501, a collision will occur. The extrusion force generated by the collision can break the raw materials and the caked raw materials. When the movable scraping strip 502 continues to move, it drives the moving ejector rod 507 and the moving slider 505 to move towards one side of the inner cavity of the movable slot 503, and squeezes the spring 504. When the movable scraping strip 502 separates from the blocking inclined strip 501, the compressed extrusion spring 504 drives the moving slider 505, the moving ejector rod 507 and the movable scraping strip 502 to reset, and the operation is cycled in turn.

Pulling springs 623 are installed around one side of the moving limiting blocks 622. One ends of the pulling springs 623 away from the moving limiting blocks 622 are connected to the inner cavity of the mounting notch 620;

[0045] The specific implementation method is as follows: When the temperature of the raw material processed inside the processing frame 1 becomes abnormal, it will be detected by the temperature controller 16, triggering the control panel to start the limiting electromagnet, the multi-control solenoid valve 610, and one end of the multi-way solenoid valve 612 connected to the conveying through-hole 611. The limiting electromagnet generates magnetism and forms magnetic attraction with the magnetic ring, driving the rotating rod 603 to rotate. The rotating rod 603 drives the vortex fan head 605 to rotate inside the converging frame head 604, and an air flow is formed inside the converging frame head 604. The air flow is transported into the conveying pipe 607, and the multi-control solenoid valve 610 sprays a small amount of liquid nitrogen in the inner cavity of the liquid nitrogen tank 609 into the conveying pipe 607 multiple times. When the air flow contacts the liquid nitrogen, a cold air flow is formed and transported into the conveying through-hole 611 through the multi-control solenoid valve 610. When the cold air flow flows inside the conveying through-hole 611, it takes away the heat of the raw material inside the processing frame 1. Finally, the air flow is sprayed into the converging frame head 604 through the nozzle, and the cyclic operation will not cause energy loss. When the temperature controller 16 feedbacks that the temperature inside the processing frame 1 has not decreased yet, the output end at the bottom of the multi-way solenoid valve 612 is started through the control panel. When the rotating rod 603 rotates, it drives the movable rotating block 619 to rotate inside the rotating notch 618, and does not drive the rotating block 613 to rotate, disconnecting the power supply of the small electromagnet 621, making the small electromagnet 621 lose magnetism. Then the moving limit block 622 loses its restraint force, and the moving limit block 622 is driven by the stretched pulling spring 623 to move inside the installation notch 620, so that one end of the moving limit block 622 moves outside the installation notch 620. When the rotating rod 603 drives the moving limit block 622 to rotate, one end of the moving limit block 622 contacts the limit rod 624 and generates a blocking force. The limit rod 624 is pushed to move through the blocking force. When the limit rod 624 rotates and moves, it drives the pulling rope 616 to move. The pulling rope 616 drives the installation rotating block 615 to rotate inside the installation rotating groove 614 with the bearing as the axis and drives the fan blades 606 to rotate, changing the angles of the surrounding fan blades 606. When the rotating angle reaches the expected position, the pulling rope 616 cannot move further and drives the rotating block 613 to rotate. The rotating block 613 drives the surrounding fan blades 606 to rotate, making the air flow stronger. When the air flow flows into the annular notch 601, the air flow sprays out through the conveying one-way valve 627 and passes through the rubber baffle 626 to transport the air flow into contact with the raw material in the processing frame 1 to adjust the temperature of the raw material. When heating, the annular resistance heating frame 15 is started. When the air passes through the inside of the annular resistance heating frame 15 and contacts the air flow formed by the vortex fan head 605, a hot air flow is formed, and the hot air flow repeats the above operation trajectory for heating treatment.

[0046] The adsorption mechanism 608 includes an adsorption frame head 6081, a blocking elastic strip 6082, a rotating plate 6083, an adsorption layer 6084, a mounting ring plate 6085, a receiving frame 6086, a receiving cotton layer 6087, and a working through groove 6088. A working through groove 6088 is opened at the upper middle side of one side of the conveying pipe 607. An adsorption frame head 6081 is installed at the relative position of the upper middle side of one side of the conveying pipe 607 and corresponding to the working through groove 6088. A mounting ring plate 6085 is installed on one side of the inner cavity of the adsorption frame head 6081 through a bearing. A plurality of rotating plates 6083 are equidistantly installed around the outside of the mounting ring plate 6085. A receiving frame 6086 is installed at the bottom end of the adsorption frame head 6081. A receiving cotton layer 6087 is installed in the inner cavity of the receiving frame 6086. Blocking elastic strips 6082 are installed at the upper end and the bottom end of one side of the inner cavity of the adsorption frame head 6081 respectively. Mounting through grooves are opened in the middle of the rotating plates 6083, and adsorption layers 6084 are installed inside the mounting through grooves. One side of each rotating plate 6083 is of an arc structure;

[0047] The specific implementation method is as follows: When cooling the raw materials inside the processing frame 1, water vapor will be generated when the liquid nitrogen takes away heat. When the air flow circulates inside the conveying pipe 607, the air flow contacts the rotating plate 6083, and the air flow drives the rotating plate 6083 to rotate with the mounting ring plate 6085 as the axis. When the air flow contacts the outside of the rotating plate 6083, the water vapor inside the air flow will be absorbed by the adsorption layer 6084. When the rotating plate 6083 rotates, a centrifugal force is generated on the adsorption layer 6084, and the liquid absorbed inside the adsorption layer 6084 is thrown out by the centrifugal force, and the thrown-out liquid contacts and is absorbed by the receiving cotton layer 6087, so that the situation of splashing will not occur. When the rotating plate 6083 rotates to the position of the blocking elastic strip 6082, it will squeeze and collide with the blocking elastic strip 6082, and vibration will be generated during the collision. The collected liquid inside the adsorption layer 6084 is vibrationally separated by the vibration force.

[0048] Working principle: When the present invention performs the stirring operation, the single-phase motor 401 is started to drive the rotating rod 406 to rotate. The rotating rod 406 drives the rotating wheel 402 on the left side to rotate, and the rotating belt 403 drives the rotating wheel 402 on the right side to rotate. When the rotating rod 406 rotates, it drives the multi-angle turntable 405 to rotate, and drives the transmission gears 415 around through the connecting rod 412. Since the transmission gear 415 at the top meshes with the fixed gear 404 and the fixed gear 404 does not rotate, the transmission gear 415 at the top rotates outside the fixed gear 404, drives the transmission gear 415 at the bottom through the connecting rod 412, and drives the rotating gear 414 to rotate. Then, the stirring frames 409 around are driven to rotate counterclockwise through the movable rod 410. Through the stirring frames 409 around, the rotating rod 406 drives the processing plates 407 around to rotate clockwise. Thus, several stirring areas are formed around the inner cavity of the processing frame 1, and the stirring areas also move inside the processing frame 1. When the processing plate 407 moves, it drives the elastic strip 408 to move, so that the elastic strip 408 contacts the outside of the stirring frame 409, and the elastic strip 408 deforms. When the stirring frame 409 continues to move, the stirring frame 409 is separated from the elastic strip 408. Through the collision, the stirring frame 409 can generate vibration, and the raw materials attached to the outside of the stirring frame 409 are shaken off;

[0049] When the multi-angle turntable 405 and the multi-angle connecting frame rotate, they drive the movable ejector rods 507 around to rotate. The movable ejector rods 507 drive the movable scraping strips 502 around to rotate. The inner cavity around the processing frame 1 is scraped by the movable scraping strips 502. When the inclined surface of the movable scraping strip 502 contacts the inclined surface of the blocking inclined strip 501, a collision will occur. Through the extrusion force generated by the collision, the raw materials and the agglomerated raw materials can be broken. When the movable scraping strip 502 continues to move, it drives the movable ejector rods 507 and the movable sliders 505 to move towards one side of the inner cavity of the movable slot 503, and the spring 504 is compressed. When the movable scraping strip 502 is separated from the blocking inclined strip 501, the compressed extrusion spring 504 drives the movable slider 505, the movable ejector rod 507 and the movable scraping strip 502 to reset, and the operation is cycled in turn;

[0050] When the temperature of the raw material processed inside the processing frame 1 becomes abnormal, it will be detected by the temperature controller 16, triggering the control panel to activate the end of the limit electromagnetic block, multi-control solenoid valve 610, and multi-way solenoid valve 612 connected to the conveying through-hole 611. This causes the limit electromagnetic block to generate magnetism and form a magnetic attraction with the magnetic ring, driving the rotating rod 603 to rotate. The rotating rod 603 drives the vortex fan head 605 to rotate inside the converging frame head 604, creating an air current inside the converging frame head 604. The air current is then transported into the conveying pipe 607, and the multi-control solenoid valve 610 sprays a small amount of liquid nitrogen from the inner cavity of the liquid nitrogen tank 609 into the conveying pipe 607 multiple times. When the air current comes into contact with the liquid nitrogen, a cold air current is formed and transported into the conveying through-hole 611 through the multi-control solenoid valve 610. As the cold air current flows through the conveying through-hole 611, it carries away the heat of the raw material inside the processing frame 1. Finally, the air current is sprayed into the converging frame head 604 through the nozzle, and this cyclic operation does not cause energy loss. When the temperature controller 16 feeds back that the temperature inside the processing frame 1 has not decreased, the output end at the bottom of the multi-way solenoid valve 612 is activated through the control panel. When the rotating rod 603 rotates, it drives the movable rotating block 619 to rotate inside the rotating notch 618, but does not drive the rotating block 613 to rotate, disconnecting the power supply of the small electromagnetic block 621 and causing the small electromagnetic block 621 to lose magnetism. Then, the moving limit block 622 loses its restraint force and is driven by the stretched pulling spring 623 to move inside the installation notch 620, moving one end of the moving limit block 622 outside the installation notch 620. When the rotating rod 603 drives the moving limit block 622 to rotate, one end of the moving limit block 622 contacts the limit rod 624 and generates a blocking force, pushing the limit rod 624 to move through this blocking force. When the limit rod 624 rotates and moves, it drives the pulling rope 616 to move. The pulling rope 616 drives the installation rotating block 615 to rotate inside the installation rotating groove 614 with the bearing as the axis and drives the fan blades 606 to rotate, changing the angles of the surrounding fan blades 606. When the rotation angle reaches the expected position, the pulling rope 616 cannot move further and drives the rotating block 613 to rotate. The rotating block 613 drives the surrounding fan blades 606 to rotate, making the air current stronger. When the air current flows into the annular notch 601, the air current sprays out through the conveying one-way valve 627 and passes through the rubber baffle 626 to transport the air current into contact with the raw material in the processing frame 1 to adjust the temperature of the raw material. When heating is started, the annular resistance heating frame 15 is activated. When the air passes through the inside of the annular resistance heating frame 15 and comes into contact with the air current formed by the vortex fan head 605, a hot air current is formed, and the hot air current repeats the above operating trajectory for heating treatment.
