Description

Technical Field

[0001] The utility model belongs to the technical field of water-soluble fertilizer production, and particularly relates to a raw material pretreatment device for water-soluble fertilizer production. Background Art

[0002] The characteristics of water-soluble fertilizers require them to be quickly and completely dissolved in water for direct absorption by plant roots or leaves. The crushing process in raw material pretreatment can significantly reduce the particle size and increase the surface area, thereby improving the dissolution rate and solubility in water, ensuring that fertilizer nutrients can be quickly released and effectively absorbed by crops. In the prior art, usually, a motor is fixedly connected to the top surface of the stirring cylinder body, the output end of the motor is fixedly connected to a transmission shaft, a stirring ring is connected to the transmission shaft, and stirring blades are arranged on the stirring ring to stir the water-soluble fertilizer raw materials. However, in this method, the stirring blades perform one-way stirring and cannot meet the requirement of simultaneously performing forward and reverse stirring on the water-soluble fertilizer raw materials. Moreover, for materials with large particle size differences and different specific gravities, one-way stirring may not ensure that all raw material particles can be effectively sheared and mixed, resulting in uneven distribution of components in the final product.

[0003] For example, the utility model with the publication number of CN219815986U discloses a raw material pretreatment device for water-soluble fertilizer production. In the technical solution of this patent, a motor is fixedly connected to the top surface of the stirring cylinder body, the output end of the motor is fixedly connected to a transmission shaft, one side of the surface of the transmission shaft is fixedly connected to a stirring ring, and the outer surface of the stirring ring is fixedly connected to stirring blades to stir and crush the water-soluble fertilizer raw materials inside the stirring cylinder. However, in this method, the stirring blades perform one-way stirring and cannot meet the requirement of simultaneously performing forward and reverse stirring on the water-soluble fertilizer raw materials. Moreover, one-way stirring may cause incomplete mixing of raw materials in some areas, especially when processing raw materials with a wide particle size distribution and large density differences, it is easy to form a mixing blind area, resulting in uneven concentration of each component in the final product. Content of the Utility Model

[0004] In view of this, aiming at the deficiencies of the prior art, the utility model provides a raw material pretreatment device for water-soluble fertilizer production, which can not only perform two-way stirring on the water-soluble fertilizer raw materials through a stirring component to ensure uniform dispersion of various components, but also scrape the side wall of the stirring barrel through a scraper to avoid uneven mixing or loss caused by long-term retention of materials on the barrel wall.

[0005] To solve the above technical problems, the technical solution adopted by the present utility model is as follows: A raw material pretreatment device for water-soluble fertilizer production, comprising a stirring barrel, an inlet pipe is arranged at the upper end of the stirring barrel, a stirring assembly is arranged inside the stirring barrel, the stirring assembly includes a rotating column arranged in the middle of the stirring barrel, stirring rollers are uniformly arranged on the outer arc surface of the lower end of the rotating column, a sleeve is sleeved on the upper end of the rotating column through a bearing, a stirring column is arranged at the lower end of the sleeve, crushing rods are uniformly arranged on the stirring column, and a driving mechanism for driving the sleeve is arranged at the upper end of the rotating column.

[0006] As a further improvement of the present utility model, the driving mechanism includes a first bevel gear arranged at the upper end of the rotating column, an installation frame is arranged at the upper end of the stirring barrel, the top of the rotating column is rotatably connected to the upper side wall of the installation frame, a helical gear meshing with the first bevel gear is rotatably arranged inside the installation frame, a second bevel gear meshing with the helical gear is arranged at the upper end of the sleeve, and a motor is arranged inside the installation frame, and the output end of the motor is connected to the helical gear through a coupling.

[0007] As a further improvement of the present utility model, a strip-shaped plate is arranged at the lower end of the rotating column, scraping plates are arranged at both ends of the strip-shaped plate, and the scraping plates are in contact with the side wall of the stirring barrel.

[0008] As a further improvement of the present utility model, a dispersion plate is arranged at one end of the sleeve located inside the stirring barrel.

[0009] As a further improvement of the present utility model, a discharge pipe is arranged at the lower end of the stirring barrel, and a discharge valve is arranged on the discharge pipe.

[0010] As a further improvement of the present utility model, a fixing ring is arranged on the stirring barrel, a plurality of support columns are arranged at the lower end of the fixing ring, and anti-slip stripes are arranged on the outer wall of the bottom of the support columns.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] Firstly, by setting the stirring assembly, starting the motor can make the helical gear rotate, thereby making the first bevel gear and the second bevel gear rotate in opposite directions. The rotation of the first bevel gear can make the stirring rollers rotate to positively stir the water-soluble fertilizer raw materials. The reverse rotation of the second bevel gear can make the stirring column rotate, and then make the crushing rods rotate in the reverse direction, thereby crushing the water-soluble fertilizer raw materials. The water-soluble fertilizer raw materials may contain components that are prone to caking or precipitation. Long-term one-way stirring may cause local overheating, increased viscosity or the formation of a stable flow pattern, thereby causing the deposition of materials at the bottom or wall of the tank. Forward and reverse stirring can periodically change the stress state of the materials, effectively inhibit the caking phenomenon, reduce sedimentation, keep the materials suspended in the tank, and ensure the stable quality of the product.

[0013] Second, a dispersion plate is provided at one end of the sleeve located inside the mixing barrel. The material can be broken up by the dispersion plate and thus enter the interior of the mixing barrel body from all directions, ensuring the subsequent mixing effect.

[0014] Third, a discharge valve is provided on the discharge pipe. As a key control element in the pipeline, the discharge valve can effectively open, close, or adjust the flow rate of the raw materials. According to the production requirements or the arrangement of the process flow, the operator can precisely control the pre-treated raw materials to be discharged at an appropriate speed and quantity by adjusting the valve opening, ensuring the stability and continuity of the subsequent production links.

[0015] Fourth, by providing a scraper, the scraper abuts against the side wall of the mixing barrel. During the mixing process, some materials are likely to adhere to the inner wall of the mixing barrel. The scraper rotates closely attached to the barrel wall, which can effectively scrape off these materials and make them participate in the mixing again, avoiding uneven mixing or loss caused by the materials staying on the barrel wall for a long time.

Specific Embodiments

[0022] To better understand the present utility model, the content of the present utility model will be further clearly elaborated below in conjunction with embodiments. However, the protected content of the present utility model is not limited to the following embodiments only. In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details.

[0023] like Figure 1 , 2 As shown in Figure 3, a raw material pretreatment device for water-soluble fertilizer production includes a stirring barrel 101, a feeding pipe 102 is provided at the upper end of the stirring barrel 101, a stirring assembly is provided inside the stirring barrel 101, the stirring assembly includes a rotating column 103 arranged in the middle of the stirring barrel 101, stirring rollers 104 are evenly arranged on the outer arc surface of the lower end of the rotating column 103, a sleeve 105 is provided at the upper end of the rotating column 103 through a bearing sleeve, a stirring column 106 is provided at the lower end of the sleeve 105, a breaking rod 107 is evenly provided on the stirring column 106, and a driving mechanism for driving the sleeve 105 is provided at the upper end of the rotating column 103.

[0024] like Figure 1 , 3 As shown, the driving mechanism includes a bevel gear 1 201 arranged at the upper end of the rotating column 103, a mounting frame 202 is arranged at the upper end of the mixing barrel, the top of the rotating column 103 is rotatably connected to the upper side wall of the mounting frame 202, a helical gear 203 meshing with the bevel gear 1 201 is rotatably arranged inside the mounting frame 202, a bevel gear 204 meshing with the bevel gear 203 is arranged at the upper end of the sleeve 105, a motor 205 is arranged inside the mounting frame 202, the output end of the motor 205 is connected to the bevel gear 203 through a coupling, and starting the motor 205 can rotate the bevel gear 203, thereby causing the bevel gear 1 201 and the bevel gear 204 to rotate. Reverse rotation, the rotation of bevel gear 1 201 can rotate the stirring roller 104, and the water-soluble fertilizer raw material is stirred in the forward direction. The reverse rotation of bevel gear 204 can rotate the stirring column 106, and then the crushing rod 107 rotates in the reverse direction, and then the water-soluble fertilizer raw material is crushed. The water-soluble fertilizer raw material may contain components that are easy to agglomerate or precipitate. Long-term unidirectional stirring may cause local overheating, increased viscosity or form a stable flow pattern, which in turn causes the material to deposit on the bottom or wall of the tank. Positive and reverse stirring can periodically change the stress state of the material, effectively inhibit agglomeration, reduce sedimentation, keep the material in a suspended state in the tank, and ensure stable product quality.

[0025] like Figure 1 , 2 As shown, a strip plate 206 is provided at the lower end of the rotating column 103, and scrapers 207 are provided at both ends of the strip plate 206. The scrapers 207 are in conflict with the side walls of the mixing barrel 101. During the mixing process, some materials are easily adhered to the inner wall of the mixing barrel 101. The scrapers 207 rotate closely with the barrel wall, which can effectively scrape these materials off and re-mix them, avoiding uneven mixing or loss due to long-term retention of materials on the barrel wall.

[0026] like Figure 1 , 2As shown, a dispersion plate 208 is provided at one end of the sleeve 105 located inside the mixing barrel 101. The material can be broken up by the dispersion plate 208 and thus enter the interior of the mixing barrel body from all directions, ensuring the subsequent mixing effect.

[0027] As Figure 1 , 4 shown, a discharge pipe 108 is provided at the lower end of the mixing barrel 101, and a discharge valve 109 is provided on the discharge pipe 108. As a key control element in the pipeline, the discharge valve 109 can effectively open, close or adjust the flow rate of the raw material. According to the production requirements or the arrangement of the process flow, the operator can precisely control the pre-treated raw material to be discharged at an appropriate speed and quantity by adjusting the valve opening, ensuring the stability and continuity of the subsequent production process.

[0028] Working principle: When using this device, first, the water-soluble fertilizer raw material is injected into the interior of the mixing barrel 101 through the feed pipe 102. The raw material falls on the dispersion plate 208, and the dispersion plate 208 can break up the material and thus enter the interior of the mixing barrel body from all directions. Then, starting the motor 205 can cause the helical gear 203 to rotate, and further cause the first bevel gear 201 and the second bevel gear 204 to rotate in opposite directions. The rotation of the first bevel gear 201 can cause the mixing roller 104 to rotate, and perform forward mixing on the water-soluble fertilizer raw material. The reverse rotation of the second bevel gear 204 can cause the mixing column 106 to rotate, and further cause the crushing rod 107 to rotate in the opposite direction, and further crush the water-soluble fertilizer raw material. The water-soluble fertilizer raw material may contain components that are prone to caking or precipitation. Long-term one-way mixing may cause local overheating, increased viscosity or the formation of a stable flow pattern, and further lead to the deposition of the material at the bottom or on the wall of the tank. Forward and reverse mixing can periodically change the stress state of the material, effectively inhibit the caking phenomenon, reduce sedimentation, keep the material in a suspended state in the tank, ensure the stability of the product quality, and the mixed and crushed material is output through the discharge pipe 108.

[0029] A discharge valve 109 is provided on the discharge pipe 108. As a key control element in the pipeline, the discharge valve 109 can effectively open, close or adjust the flow rate of the raw material. According to the production requirements or the arrangement of the process flow, the operator can precisely control the pre-treated raw material to be discharged at an appropriate speed and quantity by adjusting the valve opening, ensuring the stability and continuity of the subsequent production process.

[0030] According to another embodiment of the present invention, as Figure 1 , 4 shown, a fixing ring 110 is provided on the mixing barrel 101. A plurality of support columns 111 are provided at the lower end of the fixing ring 110. Anti-slip stripes are provided on the outer wall of the bottom of the support columns 111. The support columns 111 play a very good supporting role for the mixing barrel 101, greatly improving the stability of the mixing barrel 101.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention shall be covered by the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
