DETAILED DESCRIPTION

[0026] The technical solutions in the present application will be further described below in combination with the drawings and examples.

[0027] Please refer to Figure 1 , the present application provides the following technical solutions: a soil conditioner granule drying device, comprising a drying tank 1 arranged vertically along an axis, a preliminary drying tank 2 fixedly arranged in the drying tank 1 and coaxial with the drying tank 1;

[0028] a preliminary drying mechanism 3, comprising a plurality of preliminary drying nozzles 301 fixedly arranged in the preliminary drying tank 2 and uniformly distributed circumferentially along the preliminary drying tank 2;

[0029] a rotary feeding mechanism 4, comprising a feeding pipe 410 penetrating the top of the drying tank 1 and the top of the preliminary drying tank 2 from top to bottom, a plurality of drying cylinders 420 in communication with the feeding pipe 410, and a driving assembly 430 drivingly connected with the feeding pipe 410, wherein the air jet direction of the preliminary drying nozzle 301 is upward, the plurality of drying cylinders 420 are uniformly distributed circumferentially along the preliminary drying tank 2, the axis of the drying cylinder 420 is parallel to the preliminary drying nozzle 301, and the distance between the drying cylinder 420, the preliminary drying nozzle 301 and the axis of the preliminary drying tank 2 is the same, as shown in Figure 1 、 Figure 3 The top of the drying cylinder 420 is provided with an opening 421, and the bottom thereof is provided with an air hole 422; when the drying cylinder 420 rotates to a position corresponding to the preliminary drying nozzle 301, the hot air flow blows the material in the interior of the drying cylinder 420 through the through hole, the material particles are affected by the air flow, part of the moisture evaporates, the gravity becomes lighter and moves upward to present a suspended state, until the material moves to the upper part of the drying cylinder 420;

[0030] The air jet discharging mechanism 5 is arranged between the plurality of drying cylinders 420 and located above the drying cylinders 420. The air jet discharging mechanism 5 has a plurality of discharge nozzles 501 in the horizontal direction. The material moving above the drying cylinders 420 is acted upon by the discharge nozzles 501 and moves outward into the primary drying tank 2.

[0031] A drying and forming mechanism 6 is provided at the bottom of the primary drying tank 2 with a discharge pipe 201, and the drying and forming mechanism 6 is provided below the discharge pipe 201;

[0032] The material entering the primary drying tank 2 moves downward along the inner wall of the primary drying tank 2 and is discharged from the discharge pipe 201. The material is then dried again by the drying and forming mechanism 6, which helps the material form a dry granular form with a compact structure.

[0033] In order to facilitate the dispersion of materials into each drying cylinder 420, in a further embodiment, as Figure 2 As shown, the feed pipe 410 includes a feed portion 411 coaxially arranged with the drying tank 1, a discharge portion 412 fixed to the bottom of the feed portion 411 and horizontally arranged, and a plurality of distribution portions 413 connected to the side of the discharge portion 412 and obliquely arranged. The feed portion 411 is a tubular structure with the top located outside the drying tank 1, the discharge portion 412 is a circular box-shaped structure and coaxially connected to the feed portion 411, the discharge portion 412 is a tubular structure, and the plurality of distribution portions 413 are respectively connected to each of the drying cylinders 420. The material enters the discharge portion 412 from the feed portion 411, and under the action of the rotating centrifugal force, the material enters the drying cylinder 420 through the distribution portion 413;

[0034] In order to ensure that there is sufficient airflow into the drying cylinder 420, in a further embodiment, as Figure 3 As shown, the bottom of the drying cylinder 420 is provided with an annular eaves 423 extending outward, which can gather and collect the airflow generated by the primary drying nozzle 301;

[0035] In order to facilitate the sorting and discharge of the pre-baked materials, in a further embodiment, as Figure 2 As shown, the jet discharging mechanism 5 further includes a discharging air inlet pipe 502 that passes through the top of the drying tank 1 and the top of the primary drying tank 2 from top to bottom, and a mounting base 503 fixedly sleeved on the bottom of the discharging air inlet pipe 502. The discharging air inlet pipe 502 is fixedly connected to the drying tank 1. A plurality of discharging nozzles 501 are fixed on the mounting base 503 and evenly distributed along the circumference thereof. The feeding pipe 410 coaxially passes through the discharging air inlet pipe 502 and is rotatably connected thereto. When the material in the drying cylinder 420 is acted upon by the airflow of the primary drying nozzle 301, the evaporated water rises to a certain height and is then blown to one side by the discharging nozzle 501 and falls into the primary drying tank 2.

[0036] Specifically, as shown in the figure, the primary drying mechanism 3 further includes a primary drying air inlet pipe 302, which passes through the bottom of the drying tank 1 from bottom to top and extends from the discharge pipe 201 into the primary drying tank 2. The primary drying nozzle 301 is connected to the primary drying air inlet pipe 302 through a pipe.

[0037] In order to help the material particles after the initial drying to form dry particles with a compact structure, in a further embodiment, the drying and forming mechanism 6 includes a distribution platform 601 fixed below the discharge pipe 201, and a material guide platform 602 extending horizontally is provided at the bottom of the distribution platform 601. The material guide platform 602 is provided with evenly distributed drying and forming nozzles 603, and an inclined forming guide cloth 604 is provided above the drying and forming nozzles 603;

[0038] After being discharged from the discharge pipe 201, the material is dispersed onto the guide platform 602 by the action of the distribution platform 601. The material on the guide platform 602 is affected by the airflow of the drying and forming nozzle 603. The material particles rise again and are blocked by the forming guide cloth 604. The material particles roll along the surface of the forming guide cloth 603. On the one hand, the airflow accelerates the evaporation of water during the rolling process. On the other hand, the air pressure of the airflow and the blocking effect of the forming guide cloth 604 form a compact structure during the rolling process, which reduces the breakage of particles and ensures product quality.

[0039] In order to facilitate the adjustment of the blocking effect of the forming guide cloth 604, in a further embodiment, as Figure 1 As shown, the discharge pipe 201 is coaxially arranged with the primary drying tank 2, and an annular connecting seat 202 is provided on the discharge pipe 201. Figure 4 As shown, the drying tank 1 is provided with an annular material guide seat 605, which is bent from the inside to the outside to a vertical downward shape. The molded material guide cloth 604 is an elastic annular structure and its inner and outer sides are respectively connected to the connecting seat 202 and the material guide seat 605. A vertical telescopic component 606 is fixed on the drying tank 1 and is connected to the material guide seat 605.

[0040] The annular forming guide cloth 604 has a conical structure. The vertical telescopic assembly 606 drives the guide base 605 to move vertically. The inclination between the conical structure and the horizontal plane can be adjusted, thereby changing the strength of the forming guide cloth 604's blocking effect on material particles.

[0041] In order to facilitate the discharge of the dried and formed material, in a further embodiment, as Figure 1As shown, the material distribution platform 601 is a conical structure and its bottom extends to the outside of the discharge pipe 201. The edge of the material guide platform 602 is fixedly connected to the separation cylinder 607 located on the inner side of the material guide seat 605. The material moves along the forming material guide cloth 604, and after drying and forming, it moves along the inner surface of the material guide seat 605 to between the material guide seat 605 and the separation cylinder 607 and then falls.

[0042] In order to enhance the rolling motion of the material particles, in a further embodiment, the outer side of the material guide seat 605 is coaxially connected to a sliding seat 608 connected to the vertical telescopic assembly 606, the outer side of the material guide seat 605 is provided with a transmission gear 609, and the sliding seat 608 is fixed with a rotating drive member 610 that meshes with the transmission gear 609. The connecting seat 202 is rotatably connected to the discharge pipe 201, and multiple sets of synchronization components are provided between the material guide seat 605 and the connecting seat 202;

[0043] The material guide seat 605 is driven to rotate by the rotary drive member 610, and the material guide seat 605 drives the connecting seat 202 to rotate through the synchronization component. When the connecting seat 202 and the material guide seat 605 rotate synchronously, the forming material guide cloth 604 produces a rotating effect, and the material particles are affected by the forming material guide cloth 604 to produce a more effective rolling motion.

[0044] Specifically, the synchronization component includes a first connecting rod 611 rotatably connected to the material guide seat 605 and a second connecting rod 612 rotatably connected to the connecting seat 202. The first connecting rod 611 and the second connecting rod 612 are rotatably connected. The rotation axes of the first connecting rod 611 and the second connecting rod 612 are horizontal. The first connecting rod 611, the second connecting rod 612 and the axis of the discharge pipe 201 are located in the same vertical plane, and the first connecting rod 611 and the second connecting rod 612 only rotate in this vertical plane.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
