DETAILED DESCRIPTION

[0029] See also Figure 1-Figure 7 , the present invention provides a technical solution: a plant enzyme fertilizer preparation device, comprising a fermentation tank 11, the tank body of the fermentation tank 11 has high thermal conductivity;

[0030] A heat preservation mechanism, which is used to keep the fermentation tank 11 warm, and the heat preservation mechanism can change the heat preservation effect of the fermentation tank 11;

[0031] A stirring mechanism, which is disposed in the fermentation tank 11 and mixes the materials in the fermentation tank 11;

[0032] An external heating mechanism is used to heat the material in the fermentation tank 11 . The heating mechanism has a built-in temperature sensor, which is used to monitor the temperature of the material in the fermentation tank 11 in real time.

[0033] During operation, (during the fermentation process of the material, it is necessary to sterilize it in an environment above 70 degrees Celsius, and then ferment it in an environment of about 30 degrees Celsius) the material is placed in the fermentation tank 11. In the initial state, the heat preservation mechanism has the best heat preservation effect on the fermentation tank 11. First, the material in the fermentation tank 11 is heated by the heating mechanism to raise the temperature of the material in the fermentation tank 11 to above 70 degrees Celsius, and the temperature is maintained for an appropriate time to sterilize the material. After the sterilization, the material begins to ferment normally. During the fermentation process, the temperature of the material in the fermentation tank 11 is monitored in real time by the temperature sensor. When the temperature of the material is less than 30 degrees Celsius, the heating mechanism is used to heat the material in the fermentation tank 11. Heating, and at the same time, the heat preservation mechanism controls the heat preservation effect of the fermentation tank 11 to the best state. When the material temperature is greater than thirty degrees Celsius, the heating mechanism stops heating the material in the fermentation tank 11. At the same time, the heat preservation mechanism reduces the heat preservation effect of the fermentation tank 11 according to the degree of excess of the material temperature, so that the temperature in the fermentation tank 11 naturally drops. In this process, the material will also generate heat during fermentation, and finally the heat generated by the material during fermentation is balanced with the heat dissipated by the fermentation tank 11, so that the equipment no longer needs additional heating mechanisms or cooling mechanisms to continuously control the fermentation tank 11 for the temperature control of the fermentation tank 11; it should be noted that the stirring mechanism continuously stirs the material to make the temperature change of the material more balanced.

[0034] The present invention utilizes a heat preservation mechanism to change the heat preservation property of the fermentation tank 11, so that the heat generated during the fermentation of the material is balanced with the heat dissipated by the fermentation tank 11, so that the temperature control of the fermentation tank 11 by the equipment no longer requires an additional heating mechanism or a cooling mechanism to continuously control the fermentation tank 11. At the same time, since the heat preservation property of the fermentation tank 11 can be changed, the temperature change efficiency in the fermentation tank 11 is higher, thereby improving the fermentation efficiency of the material and reducing the maintenance difficulty of meeting the requirements of material fermentation.

[0035] As a further solution of the present invention, the stirring mechanism includes a driving device 21, which is arranged at the upper end of the fermentation tank 11. A stirring shaft 22 is vertically rotated in the fermentation tank 11. The stirring shaft 22 passes through the fermentation tank 11 and is transmission-connected to the driving device 21. The driving device 21 can control the rotation speed of the driving stirring shaft 22 according to the temperature change rate in the fermentation tank 11. A plurality of stirring fans 23 are fixedly connected to the side wall of the stirring shaft 22.

[0036] During operation, the stirring shaft 22 continuously drives the stirring fan 23 to stir the materials in the fermentation tank 11 through the power provided by the driving device 21, so that the materials in the fermentation tank 11 are mixed, thereby accelerating the heat exchange speed of the materials in the fermentation tank 11 and making the temperature change of the materials more stable and uniform.

[0037] As a further solution of the present invention, the heat-insulating mechanism includes four heat-insulating mechanisms distributed in a circular array with the fermentation tank 11 as the center. The heat-insulating mechanisms are all arranged to slide radially along the horizontal cross-section of the fermentation tank 11, and the lower end of the heat-insulating mechanism is provided with a feeding mechanism, which controls the heat-insulating mechanism to move away from or close to the side wall of the fermentation tank 11; when the four heat-insulating mechanisms are close to the side wall of the fermentation tank 11, they can jointly form an insulating cylinder that completely wraps the side wall of the fermentation tank 11; a heat-dissipating mechanism is provided at the lower end of the fermentation tank 11, and the heat-dissipating mechanism is used to control the heat preservation of the bottom of the fermentation tank 11.

[0038] As a further solution of the present invention, the insulation mechanism includes a vertically arranged connecting rod 41, and three parallel arc plates 42 are arranged at the upper end of the connecting rod 41 for radial sliding along the horizontal cross-section of the fermentation tank 11. A control mechanism is arranged at the upper end of the connecting rod 41, and the control mechanism can control the three arc plates 42 to approach or move away from each other. The control mechanism can control the three arc plates 42 to approach or move away from the side wall of the fermentation tank 11.

[0039] As a further solution of the present invention, the heat dissipation mechanism includes a base 51, and a plurality of support rods 52 are vertically fixedly connected to the upper end of the base 51, and the upper ends of the plurality of support rods 52 are fixedly connected to the lower end of the fermentation tank 11, and the side walls of the plurality of support rods 52 are vertically slidably connected with an insulation plate 53, and a lifting mechanism is arranged at the lower end of the insulation plate 53, and the lifting mechanism is used to control the vertical displacement of the insulation plate 53.

[0040] As a further solution of the present invention, the control mechanism includes a bottom plate 61, which is fixedly connected to the side wall of the base 51, and a vertically arranged mounting plate 62 is fixedly connected to the middle position of the upper end of the bottom plate 61. The mounting plate 62 is fixedly connected to a first elastic telescopic rod 63, and the first elastic telescopic rod 63 is fixedly connected to the right end of the connecting rod 41. The upper end of the connecting rod 41 is fixedly connected to a first slide rail 64, and an arc plate 42 close to the fermentation tank 11 is fixedly connected to the upper end of the first slide rail 64, and the other two arc plates 42 are slidably connected to the first slide rail 64. A dispersion mechanism is arranged in the first slide rail 64, and the dispersion mechanism is used to control the three arc plates 42 to approach or disperse each other.

[0041] As a further solution of the present invention, the dispersion mechanism includes a second slide rail 71, the upper end of the second slide rail 71 is fixedly connected to a slide rod 72, the slide rod 72 is vertically slidably connected to the lower end of a middle arc-shaped plate 42, the two side walls of the second slide rail 71 are fixedly connected to the first slider 73, the two inner side walls of the first slide rail 64 are provided with an L-shaped groove 74, the short side of the L-shaped groove 74 is vertically arranged, and the long side of the L-shaped groove 74 is horizontally arranged, the first slider 73 is slidably connected to the L-shaped groove 74, and the first slide rail 64 and the second slide rail 71 are externally connected. There is an elastic member, which applies an elastic force to the second slide rail 71 in the direction of the fermentation tank 11; a second slider 75 is arranged on the inner side of the second slide rail 71, and an inner wall of the second slide rail 71 is provided with an inclined first slide groove 76; the end of the first slide groove 76 close to the fermentation tank 11 is at the top, and the end away from the fermentation tank 11 is at the bottom; the second slider 75 is elastically slidably connected to the first slide groove 76, and a cylinder 77 is fixedly connected to the side of the upper end of the bottom plate 61 away from the fermentation tank 11, and the output shaft of the cylinder 77 is fixedly connected to the second slider 75.

[0042] During operation, when the temperature of the material does not rise to more than 30 degrees Celsius, the cylinder 77 does not work. At this time, under the elastic force of the first elastic telescopic rod 63, the connecting rod 41 is squeezed toward the fermentation tank 11. Further, the connecting rod 41 squeezes the arc plate 42 closest to the fermentation tank 11 toward the side wall of the fermentation tank 11 through the first slide rail 64. At the same time, under the elastic force of the external elastic member, the second slide rail 71 drives the middle arc plate 42 to move closer to the arc plate 42 closest to the fermentation tank 11. Under the elastic force between the second slider 75 and the first slide groove 76, the second slider 75 drives the arc plate 42 farthest from the fermentation tank 11 to move closer to the middle arc plate 42. At this time, all three arc plates 42 are close to The second slider 75 is moved away from the fermenter 11 by the cylinder 77 (correspondingly, the arc plate 42 farthest from the fermenter 11 moves away from the fermenter 11). At this time, the second slider 75 slides along the first slide groove 76 relative to the second slide rail 71. Since the first slide groove 76 is inclined, the second slider 75 presses the second slide rail 71 upward during the sliding process. The second slide rail 71 moves upward, and correspondingly, the first sliders 73 on both sides of the second slide rail 71 move vertically upward from the short side to the long side of the L-shaped groove 74 (before the first slider 73 enters the long side, the first slider 73 cannot move horizontally, and the corresponding middle arc plate 42 cannot move horizontally), until the second slider 75 slides to the end of the first slide groove 76, and the corresponding first slider 73 enters the long side of the L-shaped groove 74. At this time, the cylinder 77 continues to drive the second slider 75 away from the fermentation tank 11, and the second slider 75 drives the second slide rail 71 away from the fermentation tank 11 by pulling the second slide rail 71 (correspondingly, the arc plate 42 in the middle position moves away from the fermentation tank 11). During this process, the first slider 73 slides along the long side of the L-shaped groove 74. Further, when the second slide rail 71 slides to the limit position in the first slide rail 64, the second slide rail 71 drives the first slide rail 64 to overcome the elastic force of the first elastic telescopic rod 63 and move away from the fermenter 11 (correspondingly, the arc plate 42 closest to the fermenter 11 moves away from the fermenter 11). Further, the equipment completes the action of the three arc plates 42 gradually moving away from the fermenter 11, so that the thermal insulation of the side wall of the fermenter 11 can gradually change, and then the thermal insulation of the side wall of the fermenter 11 can better adapt to the heat dissipation demand of the heat generated by the material during the fermentation process of the material.

[0043] The present invention provides three arc plates 42 that can be sequentially away from the side wall of the fermentation tank 11, so that the thermal insulation of the side wall of the fermentation tank 11 can be gradually changed, thereby making the thermal insulation of the side wall of the fermentation tank 11 better meet the heat dissipation requirements of the heat generated by the material during the fermentation process.

[0044] As a further solution of the present invention, the lifting mechanism includes a track plate 81, which is fixedly connected to the lower end of the insulation plate 53. The track plate 81 is vertically slidably connected to the overlapping support rod 52. The track plate 81 is provided with a second slide groove 82 in the radial direction of the fermentation tank 11 corresponding to the direction of the bottom plate 61. The second slide groove 82 is respectively composed of an inclined section 821 close to the center of the track plate 81 and a straight section 822 away from the center of the track plate 81. The connecting rod 41 is fixedly connected to a guide rod 83 arranged radially along the fermentation tank 11 on one side close to the track plate 81. The guide rod 83 is composed of a straight rod 831 close to the center of the track plate 81 and a wedge rod 832 away from the center of the track plate 81. The straight section 822 and the straight rod 831 are of the same length, and the inclined surfaces of the inclined section 821 and the wedge rod 832 are parallel and of the same length.

[0045] During operation, when the heat preservation of the side wall of the fermentation tank 11 is the highest, the corresponding arc plate 42 is close to the side wall of the fermentation tank 11, and the connecting rod 41 is closest to the track plate 81. Correspondingly, the end of the straight section 822 away from the center of the track plate 81 coincides with the end of the wedge rod 832 away from the center of the track plate 81, and the end of the straight rod 831 close to the center of the track plate 81 coincides with the end of the inclined section 821 close to the center of the track plate 81. At this time, the track plate 81 is at its highest stroke, and the insulation plate 53 is close to the bottom of the fermentation tank 11, which is conducive to the fermentation of the fermentation tank 11. The bottom is insulated; and then when the equipment controls the thermal insulation of the side wall of the fermentation tank 11 to decrease, until the arc plate 42 closest to the side wall of the fermentation tank 11 begins to move away from the side wall of the fermentation tank 11, the connecting rod 41 begins to move away from the side wall of the fermentation tank 11, and the corresponding connecting rod 41 drives the guide rod 83 to start moving away from the fermentation tank 11, so that the track plate 81 and the insulation plate 53 slide down and fall along the inclined surface of the inclined section 821 and the wedge rod 832 under the action of gravity, and then the insulation plate 53 gradually moves away from the bottom of the fermentation tank 11, so that the thermal insulation of the bottom of the fermentation tank 11 decreases.

[0046] The present invention provides a heat preservation plate 53 that can gradually move away from the bottom of the fermentation tank 11, so that the heat preservation of the bottom of the fermentation tank 11 can also be changed, and further, the change of the overall heat preservation of the fermentation tank 11 is made more flexible, and the temperature change efficiency of the fermentation tank 11 is further improved.
