Description

Technical Field

[0001] The invention relates to the technical field of liquid fertilizers, in particular to a concentrating device for organic liquid fertilizers and waste liquids. Background Art

[0002] At present, with the promotion and application of pipeline fertilization technology, drip irrigation and sprinkler fertilization technology have begun to become popular in my country. The application of this technology requires the fertilizer to be dissolved in water. However, most of the compound fertilizers produced by domestic manufacturers are in solid form, such as granular form for easy spreading. This type of compound fertilizer is difficult to dissolve in water, so it is not convenient to use as a water-soluble fertilizer. Moreover, in the production process of granular compound fertilizers, it is difficult to add organic nutrients due to the need for granulation. Generally, high-concentration compound fertilizers contain inorganic components, which will have certain adverse effects on the physical structure and chemical properties of the soil during long-term application. Therefore, organic liquid fertilizers have appeared on the market.

[0003] At present, organic liquid biofertilizer is mainly prepared by fermenting organic solids, using certain process methods and adding some additives or biological strains.

[0004] In the production process of organic liquid biofertilizer, due to the different types and formulas of organic liquid fertilizers, when producing different types of fertilizers, it is necessary to clean the relevant equipment, generating a large amount of sewage and wastewater, which cannot be directly discharged into the river and needs to be treated. Since the main components of sewage include organic matter, inorganic salts such as nitrogen, phosphorus, potassium, heavy metals, etc., most of the existing technologies use evaporation and concentration processes to treat such sewage; of course, evaporation and concentration processes can also be used to control the water content in organic liquid fertilizers in order to control the concentration of organic liquid fertilizers.

[0005] For example, the invention patent with publication number CN111747468B discloses a heat pump vacuum low-temperature evaporation and concentration system. Although it provides a heat pump vacuum low-temperature evaporation and concentration system with low-temperature stable operation, high evaporation and concentration efficiency, low maintenance cost and long service life, it realizes the removal of water vapor, condensed water and non-condensable gas, and improves the evaporation and concentration efficiency of the evaporation tank; however, in actual use, when the wastewater in the evaporation tank is heated for evaporation and concentration, it is difficult to be heated evenly in the early stage of evaporation, resulting in uneven wastewater temperature, thereby reducing the evaporation efficiency. At the same time, scale will form on the inner wall of the evaporation tank after a period of use, affecting heat transfer and thus affecting the evaporation and concentration efficiency.

[0049] In this embodiment, a waste liquid inlet 103 connected to the inner tank 210 is provided at the top of the evaporation tank body 10, and a detachable sealing cover (not shown in the figure) is installed on the waste liquid inlet 103. Organic liquid fertilizer or waste liquid can be put into the inner tank 210 through the waste liquid inlet 103. In actual use, the evaporation tank body 10 is connected to an existing heat pump system, and the heat pump system is used to transport hot steam into the heating chamber 201. The hot steam in the heating chamber 201 heats the organic liquid fertilizer or waste liquid in the inner tank 210, thereby evaporating and concentrating the organic liquid fertilizer or waste liquid in the inner tank 210;

[0050] A connecting pipe 104 is provided on the top of the evaporation tank body 10, and the connecting pipe 104 is used to connect to an existing condenser so that water vapor evaporated from the organic liquid fertilizer or waste liquid in the inner tank 210 can enter the condenser for condensation and collection;

[0052] In this embodiment, the stirring component and the flow stirring component are arranged so that the two can better stir the organic liquid fertilizer or waste liquid in the inner tank 210, so that the organic liquid fertilizer or waste liquid produces a turbulent flow, and then the organic liquid fertilizer or waste liquid is heated evenly, thereby ensuring its early evaporation efficiency;

[0053] Among them, by setting the stirring shaft 220 and the stirring plate 221, the stirring shaft 220 can rotate to drive the stirring plate 221 to stir the organic liquid fertilizer or waste liquid in the inner tank 210, so that the hot steam in the heating chamber 201 can evenly heat the organic liquid fertilizer or waste liquid in the inner tank 210, thereby ensuring its early evaporation efficiency;

[0054] In actual use, the stirring plate 221 is vibrated along the stirring shaft 220, so that the stirring shaft 220 rotates to drive the stirring plate 221 to stir the organic liquid fertilizer or waste liquid in the inner tank 210. The vibration of the stirring plate 221 can make the stirring plate 221 stir the organic liquid fertilizer or waste liquid at different positions to improve the stirring effect. At the same time, it can prevent the organic liquid fertilizer or waste liquid from adhering to the stirring plate 221, so that the stirring effect of the stirring assembly is better.

[0055] In actual use, a motor 120 for driving the stirring shaft 220 to rotate is provided at the top of the evaporation tank 10, and the motor 120 can be used to drive the stirring assembly to work; Figure 10-11 As shown, in order to stably install the stirring shaft 220 in the inner tank 210, a mounting frame 1010 is provided in the discharge port 202, and the lower end of the stirring shaft 220 is rotatably mounted on the mounting frame 1010 through a bearing, so that the stirring shaft 220 is stably rotatably mounted;

[0056] Among them, by setting the stirring component, the rotation of the stirring shaft 220 can drive the first driving component to drive the stirring component to reciprocate and lift the organic liquid fertilizer or waste liquid along the radial direction of the inner tank 210, so that the organic liquid fertilizer or waste liquid flows circumferentially along the inner tank 210 under the action of the stirring component. At the same time, the organic liquid fertilizer or waste liquid can reciprocate along the radial direction of the inner tank 210 under the action of the stirring component, so that the organic liquid fertilizer or waste liquid in the inner tank 210 generates turbulence, so that the hot steam in the heating chamber 201 heats the organic liquid fertilizer or waste liquid more evenly, thereby ensuring the evaporation efficiency in the early stage;

[0057] Among them, by setting the descaling component, the rotation of the stirring shaft 220 can drive the second driving component to drive the descaling component to scrape the inner wall of the inner tank 210, which can better avoid the formation of scale on the inner wall of the inner tank 210, thereby affecting the inner tank 210 to transfer heat to the organic liquid fertilizer or waste liquid, that is, affecting the heating of the organic liquid fertilizer or waste liquid;

[0058] Among them, by setting the driving member, during the operation of the stirring component, the driving member can be driven to drive the descaling component away from the inner wall of the inner tank 210, thereby preferably creating a gap between the descaling component, the stirring component and the inner wall of the inner tank 210, thereby facilitating the flow of the organic liquid fertilizer or waste liquid between the stirring component and the corresponding descaling component, avoiding a blind spot where the water flow is relatively stable between the two, thereby making the flow of the organic liquid fertilizer or waste liquid in the inner tank 210 more turbulent, improving the hot steam in the heating chamber 201 to evenly heat the organic liquid fertilizer or waste liquid in the inner tank 210, thereby ensuring the evaporation efficiency in the early stage;

[0059] In actual use of this embodiment, in order to improve the heating effect of the hot steam in the heating chamber on the organic liquid fertilizer or waste liquid in the inner tank, a partition for dividing the heating chamber 201 into a plurality of heat exchange chambers is evenly arranged along the circumference of the evaporation tank body 10 in the heating chamber 201, and an air inlet pipe 101 and an air outlet pipe 102 communicating with the corresponding heat exchange chambers are provided on the side wall of the outer tank 110.

[0060] Combination Figure 10-11 As shown, in this embodiment, the stirring plates 221 are evenly arranged on a lifting cylinder 910, and the outer wall of the stirring shaft 220 is concave to form a lifting groove for installing the lifting cylinder 910. A vibrating member is provided at the lower end of the stirring shaft 220. The rotation of the stirring shaft 220 is used to drive the vibrating member to drive the lifting cylinder 910 to vibrate at intervals.

[0061] In this embodiment, the lifting cylinder 910 can be lifted and lowered in the lifting cylinder by setting the lifting slot, wherein the lifting cylinder 910 and the side wall of the lifting slot are matched by key slots, that is, the rotation of the stirring shaft 220 can drive the lifting cylinder 910 to rotate, thereby realizing the rotation and stirring of the stirring plate 221;

[0062] The vibrating element is provided so that when the stirring shaft 220 drives the lifting cylinder 910 to rotate, the lifting cylinder 910 can be driven to move up and down and vibrate in the lifting tank.

[0063] In this embodiment, the vibrating member includes a mounting frame 1010, and the lower end of the stirring shaft 220 is rotatably mounted on the mounting frame 1010. A convex ring 1020 is provided on the mounting frame 1010 corresponding to the lower end of the lifting cylinder 910. The convex ring 1020 is evenly distributed with matching grooves 1021, and the side wall of the matching groove 1021 is provided with an inclined sliding surface 1022.

[0064] The bottom wall of the lifting cylinder 910 is evenly provided with guide rods 1030 that can extend into the corresponding matching grooves 1021. The upper end of the lifting groove is provided with a fifth spring 920 that pushes the lifting cylinder 910 to move downward. The rotation of the lifting cylinder 910 is used to drive the guide rod 1030 to slide out of or into the matching groove 1021 along the inclined sliding surface 1022 to achieve its vibration.

[0065] Through the structure in this embodiment, in actual use, the fifth spring 920 always pushes the lifting cylinder 910 to move downward along the lifting groove, that is, drives the guide rod 1030 to abut the upper end surface of the convex ring 1020, wherein, since the mounting frame 1010 is fixedly installed, at the same time, an inclined sliding surface 1022 is provided on one side of the matching groove 1021, and a vertical surface is formed on the other side, thereby making the rotation of the stirring shaft 220 drive the lifting cylinder 910 to rotate, and can drive the guide rod 1030 to slide out along the inclined sliding surface 1022 or slide into the matching groove 1021 from the vertical surface, thereby realizing the interval vibration of the lifting cylinder 910, that is, realizing the interval vibration of the stirring plate 221, thereby improving the stirring effect of the stirring assembly.

[0066] Combination Figure 3-6 As shown, in this embodiment, the agitator assembly includes a long strip block 230 arranged on the inner wall of the inner tank 210 along the height direction of the inner tank 210, and a lifting block 240 is slidably provided on the outside of the long strip block 230 along its height direction. Mounting plates 311 are provided at the upper and lower ends of the lifting block 240 along the radial direction of the inner tank 210, and a stirrer plate 241 that can slide radially along the inner tank 210 is provided between the mounting plates 311.

The lifting member is used to drive the agitator plate 241 to slide back and forth radially along the inner tank 210 when the lifting block 240 moves up and down.

[0067] In this embodiment, the long block 230 is fixedly installed on the inner wall of the inner tank 210, and the two opposite side walls thereof are provided with limiting grooves along the height direction thereof, and one side of the lifting block 240 is concave to form a slot for the long block 230 to be inserted into, and the side wall opposite to the slot is provided with a limiting block inserted into the corresponding limiting groove, thereby preferably realizing the lifting and lowering installation of the lifting block 240 on the corresponding long block 230;

[0069] By setting the first driving component and the lifting member, when the lifting block 240 is lifted and lowered along the corresponding long block 230, the lifting member can drive the agitator plate 241 to slide back and forth along the mounting plate 311, thereby causing the agitator plate 241 to push the water flow to move circumferentially along the radial direction of the inner tank 210, thereby better causing turbulence in the organic liquid fertilizer or waste liquid in the inner tank 210.

[0070] In this embodiment, the upper end of the long block 230 is provided with a mounting column 511 located in the lifting block 240, and the upper ends of the lifting blocks 240 are connected by a connecting plate 520.

The side walls of the grooves 411 are relatively provided with guide slopes 412. The first driving assembly also includes a lever 321 evenly distributed at the upper end of the stirring shaft 220 and can be extended into the corresponding groove 411. The rotation of the stirring shaft 220 is used to drive the lever 321 to slide out or slide into the groove 411 along the guide slope 412 to realize the lifting and lowering of the lifting block 240.

[0072] Through the structure in this embodiment, under the action of the first spring 530, the lifting block 240 is driven to move upward, so that the lever 321 is located in the corresponding groove 411. At this time, the lifting block 240 is at the highest point. At this time, the rotation of the stirring shaft 220 can drive the lever 321 to rotate, so that the lever 321 can slide out of the groove 411 along the guide slope 412, thereby moving the lifting block 240 downward. The stirring shaft 220 continues to drive the lever 321 to rotate, so that the lever 321 slides into the corresponding groove 411 along the guide slope 412, so that the lifting block 240 moves up and resets. Therefore, when the stirring shaft 220 continues to rotate, it can better drive the lifting block 240 to rise and fall.

[0073] In this embodiment, the lifting member includes a fixed block 421, a mounting cavity 601 with an opening facing the corresponding agitator plate 241 is provided in the fixed block 421, a blocking plate 610 is provided at the opening of the mounting cavity 601, a top rod 620 is provided in the mounting cavity 601, one end of which passes through the blocking plate 610 and is connected to the corresponding agitator plate 241, and the other end of the top rod 620 passes through the fixed block 421 and extends into the lifting block 240, and a retaining ring 66 is provided on the top rod 620 located in the mounting cavity 601. 21, the push rod 620 is sleeved with a second spring 630 for pushing the retaining ring 621 to move into the installation cavity 601; the long block 230 is provided with a driving groove 641 corresponding to the fixed block 421 for the other end of the push rod 620 to extend into, and a side wall of the driving groove 641 is provided with an inclined surface 642. The lifting block 240 moves downward to drive the push rod to slide out of the driving groove 641 along the inclined surface 642, so that the push rod 620 drives the agitator 241 away from the fixed block 421.

[0074] In this embodiment, the fixed block 421 is arranged at the middle position of the lifting block 240 along the radial direction of the inner tank 210. Through the above structure, in the initial state, the second spring 630 drives the retaining ring 621 to drive the other end of the push rod 620 to extend into the driving groove 641. At this time, the lifting block 240 is at the highest point. At the same time, the push rod 620 drives the agitator plate 241 to approach the fixed block 421. When the lifting block 240 moves downward, the inclined surface 642 squeezes the push rod 620 to make the push rod 6 20 moves out of the driving groove 641, even if one end of the push rod 620 drives the agitator 241 to move toward the end away from the fixed block 421, when the lifting block 240 moves up and resets, the push rod 620 slides into the driving groove 641 along the inclined surface 642 under the action of the second spring 630, even if one end of the push rod 620 drives the agitator 241 to move toward the end close to the fixed block 421, thereby preferably realizing that the agitator 241 pushes the water flow to make a circumferential motion along the radial direction of the inner tank 210.

[0075] In combination with those shown in Figures 7-9, in this embodiment, the descaling component includes a descaling frame 330 and a sliding block 710 slidably arranged in the descaling frame 330, a fixed cavity 811 is arranged in the sliding block 710, a descaling rod 340 extending from the upper end is arranged in the fixed cavity 811, and scrapers 341 for scraping the inner wall of the inner tank 210 are evenly distributed on the descaling rod 340, and the second driving component is used to drive the descaling rod 340 to rise and fall to drive the scraper 341 to scrape the inner wall of the inner tank 210.

[0076] In actual use of this embodiment, one end of the descaling frame 330 is fixedly installed on the inner wall of the inner tank 210, and the sliding block 710 is radially slidably installed in the corresponding descaling frame 330 along the inner tank 210;

[0077] The scraper 341 is arranged along the circumference of the inner tank 210, and can fit with the inner wall of the inner tank 210. At the same time, its two ends are respectively slidably fitted with the side walls of the corresponding lifting blocks 240, thereby ensuring that the scraper 341 can scrape the inner wall of the inner tank 210 between adjacent stirring components.

[0078] Through the above-mentioned structure, the second driving component of this embodiment can drive the descaling rod 340 to rise and fall in the sliding block 710, thereby driving the scraper 341 to scrape the inner wall of the inner tank 210 up and down, thereby preventing scale from forming on the inner wall of the inner tank 210 and affecting the heating effect of the organic liquid fertilizer or waste liquid.

[0079] In this embodiment, a mounting ring 821 is provided on the descaling rod 340 located in the fixed cavity 811, and a third spring 830 for driving the mounting ring 821 to move downward is sleeved on the descaling rod 340 located in the fixed cavity 811, and the lower end of the descaling rod 340 extends through the sliding block 710;

[0080] The second driving assembly includes a driving block 350 connected to the stirring shaft 220 through a driving rod 351. The driving block 350 is provided with a lifting slope 352. The rotation of the stirring shaft 220 drives the driving block 350 to rotate, which is used to drive the lifting slope 352 to lift the lower end of the descaling rod 340 to realize the lifting and lowering of the descaling rod 340.

[0081] Through the structure of this embodiment, the rotation of the stirring shaft 220 can drive the driving block 350 to rotate along the circumference of the inner tank 210 through the driving rod 351, so that during the rotation, the lifting inclined surface 352 squeezes the lower end of the descaling rod 340, so that the descaling rod 340 moves up along the lifting inclined surface 352. When the lower end of the descaling rod 340 is separated from the lifting inclined surface 352, the descaling rod 340 is moved down and reset under the action of the third spring 830, thereby better realizing the lifting and lowering of the descaling rod 340 and realizing the scraper 341 to scrape the inner wall of the inner tank 210 up and down;

[0082] It should be pointed out that the driving block 350 in this embodiment is set as one, thereby, the rotation of the stirring shaft 220 drives the driving block 350 to rotate, and in turn drives the descaling rod 340 to rise and fall, thereby reducing the scraping frequency of the scraper 341 on the inner wall of the inner tank 210, and avoiding the scraper 341 from damaging the inner wall of the inner tank 210 due to high-frequency scraping.

[0083] In this embodiment, the upper and lower side walls of the descaling frame 330 are provided with a slide groove 721 for the descaling rod 340 to slide through along the radial direction of the inner tank 210, and a threaded rod 840 is provided on one side wall of the sliding block 710, and a fourth spring 850 is sleeved on the threaded rod 840 for driving the descaling frame 330 to move toward the inner wall of the inner tank 210; the driving member includes an extension plate 711 that is relatively arranged on the opposite side surfaces of the sliding block 710 and extends to the corresponding lifting block 240, and an extrusion plate 422 is provided at the lower end of the lifting block 240, and an extrusion inclined surface 423 that matches the corresponding extension plate 711 is provided on the extrusion plate 422. The lifting block 240 moves downward to drive the extrusion inclined surface 423 to squeeze the extension plate 711, thereby driving the sliding block 710 away from the inner wall of the inner tank 210.

[0084] In this embodiment, one end of the threaded rod 840 that passes through the descaling frame 330 is threadedly connected with a nut, thereby preferably achieving the installation of the sliding block 710 and the fourth spring 850 in the descaling frame 330;

[0085] The fourth spring 850 is arranged so that the sliding block 710 is always pushed to move toward the inner wall of the inner tank 210, thereby better ensuring that the scraper 341 is in contact with the inner wall of the inner tank 210, so as to facilitate the scraping of the inner wall of the inner tank 210;

[0086] Through the structure in this embodiment, when the lifting block 240 descends, it drives the extrusion plate 422 to move downward, and then the extrusion slope 423 thereon squeezes the upper side wall of the corresponding extension plate 711, thereby pushing the sliding block 710 to move in the descaling frame 330 toward the direction away from the inner wall of the inner tank 210, so that the scraper 341 is away from the inner wall of the inner tank 210. As a result, a gap is generated in the blind area where the water flow is relatively stable at the intersection of the lifting block 240 and the inner wall of the inner tank 210, so that the turbulent flow generated by the stirring component and the flow stirring component flows through the blind area, thereby improving the turbulent flow of the organic liquid fertilizer or waste liquid in the inner tank 210, thereby improving the effect of the hot steam in the heating chamber 201 on the uniform heating of the organic liquid fertilizer or waste liquid in the inner tank 210.

[0087] Working principle: the organic liquid fertilizer or waste liquid is put into the inner tank 210 through the waste liquid inlet 103, and then the heat pump system is used to transport hot steam into the heating chamber 201 to heat the organic liquid fertilizer or waste liquid in the inner tank 210. At the same time, the motor 120 is started to drive the stirring shaft 220 to rotate, and the stirring plate 221 is driven to rotate to stir the organic liquid fertilizer or waste liquid. At the same time, the stirring plate 241 is driven to push the water flow to move in a circumferential direction along the radial direction of the inner tank 210, thereby causing turbulence in the organic liquid fertilizer or waste liquid, thereby improving the uniform heating of the organic liquid fertilizer or waste liquid; at the same time, the rotation of the stirring shaft 220 can drive the descaling rod 340 to rise and fall at intervals, bringing The movable scraper 341 scrapes the inner wall of the inner tank 210 between adjacent stirring components to prevent scale from forming on the inner wall of the inner tank 210, which would affect the heating of the organic liquid fertilizer or waste liquid. At the same time, the lifting and lowering of the lifting block 240 can drive the scraper 341 away from the inner wall of the inner tank 210, thereby creating a gap in the blind area where the lifting block 240 intersects the inner wall of the inner tank 210 where the water flow is relatively stable, so that the turbulent flow generated by the stirring component and the stirring component flows through the blind area, thereby improving the turbulent flow of the organic liquid fertilizer or waste liquid in the inner tank 210, thereby improving the effect of the hot steam in the heating chamber 201 on uniformly heating the organic liquid fertilizer or waste liquid in the inner tank 210.

[0088] In conclusion, the above is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
