Description

Technical Field

[0001] The utility model relates to the field of biological organic fertilizer production, in particular to a cooler for biological organic fertilizer production. Background Technique

[0002] Biological organic fertilizer refers to a kind of fertilizer that combines the effects of microbial fertilizer and organic fertilizer, which is composed of specific functional microorganisms and mainly organic materials derived from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) and subjected to harmless treatment and composting.

[0003] In the processes of composting and harmless treatment, the temperature of the materials will rise. Until after the final drying process, the biological organic fertilizer still has a relatively high temperature and can only be packaged or directly used after cooling; the natural cooling time is long, so coolers are often used in the prior art for cooling. The cooling method of multi-layer conveyor belts and ventilation from bottom to top can achieve the cooling effect, but the wind directly contacts the biological organic fertilizer, which has the adverse effect of air drying and increases the oxygen content, affecting the subsequent storage environment of the biological organic fertilizer.

[0004] Therefore, in order to solve the above problems, a cooler for biological organic fertilizer production is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a cooler for biological organic fertilizer production, which cools by direct contact, so as to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A cooler for biological organic fertilizer production, including a tank body. At the center of the top and bottom of the tank body, central sleeves are connected and installed. The same hollow tube is rotatably installed in the central sleeves. Both ends of the hollow tube protrude out of the central sleeves. Hollow spiral blades are connected and installed on the circumferential side of the hollow tube. The hollow spiral blades are located inside the tank body, and the edges of the hollow spiral blades are in contact with the inner side wall of the tank body. One ends of rotary joints are rotatably installed at both ends of the hollow tube, and the other ends of the rotary joints are connected and installed with docking pipes. A cold medium passes through the inside of the hollow tube and the hollow spiral blades from bottom to top; a driving component for rotating the hollow tube is installed on the upper side of the tank body. A feeding port is opened at the top of the tank body, and a discharging port is opened at the bottom of the tank body.

[0008] Specifically, the cold medium is cold water.

[0009] Specifically, the driving assembly includes a reduction motor, a driving bevel gear, and a driven bevel gear. The reduction motor is fixedly installed on the upper side of the tank body. The output end of the reduction motor is fixedly installed with the driving bevel gear. The circumferential side of the hollow tube is fixedly installed with the driven bevel gear. The driven bevel gear is located between the tank body and the rotary joint. The driving bevel gear and the driven bevel gear are meshed and assembled.

[0010] Furthermore, an isolation cover is fixedly installed on the upper side of the tank body. The driving bevel gear and the driven bevel gear are located inside the isolation cover. The isolation cover is provided with through holes for passing through the hollow tube and the output end of the reduction motor.

[0011] Specifically, the bottom of the tank body is in the shape of a conical cylinder, and the bottom diameter of the hollow spiral blade also gradually decreases.

[0012] Specifically, a socketed clamp is installed between the tank body and the docking pipe.

[0013] Specifically, a feed hopper is fixedly installed at the feed inlet, and a discharge pipe is fixedly installed at the discharge outlet.

Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1 and Figure 2 The present invention provides a cooler for producing biological organic fertilizer, including a tank body 1. Central sleeves are connected and installed at the center of the top and the center of the bottom of the tank body 1. The same hollow pipe 6 is rotatably installed in the central sleeves. Both ends of the hollow pipe 6 extend out of the central sleeves. A hollow spiral blade 9 is connected and installed on the circumferential side of the hollow pipe 6. The hollow spiral blade 9 is located inside the tank body 1, and the edge of the hollow spiral blade 9 is in contact with the inner side wall of the tank body 1. One end of a rotary joint 4 is rotatably installed at both ends of the hollow pipe 6, and the other end of the rotary joint 4 is connected and installed with a butt joint pipe 5. A cold medium passes through the inside of the hollow pipe 6 and the hollow spiral blade 9 from bottom to top; a drive assembly 3 for rotating the hollow pipe 6 is installed on the upper side of the tank body 1. A feed inlet is opened at the top of the tank body 1, and a discharge outlet is opened at the bottom of the tank body 1.

[0025] The rotary joint 4 is an existing component, and a rotary sealing ring is also installed between the central sleeve and the hollow pipe 6.

[0026] The drive assembly 3 can rotate the hollow pipe 6 and the hollow spiral blade 9. The biological organic fertilizer enters from the feed inlet and falls on the hollow spiral blade 9, and is conveyed downward along the surface of the hollow spiral blade 9 to the discharge outlet and discharged. The rotating hollow spiral blade 9 gives the biological organic fertilizer an upward acting force, but does not convey the biological organic fertilizer upward, which plays a role in delaying the downward conveyance of the biological organic fertilizer, increasing the contact time between the biological organic fertilizer and the hollow spiral blade 9. At the same time, the cold medium passing through the hollow pipe 6 and the hollow spiral blade 9 from bottom to top can cool the biological organic fertilizer.

[0027] Specifically, the cold medium is cold water. The two butt joint pipes 5 are connected to an external cooling water tank. The cooling water tank can generate cold water and supply it to the hollow pipe 6. The heat-exchanged water then enters the cooling water tank for cooling treatment to achieve continuous supply of cold water.

[0028] Specifically, as Figure 3As shown, the driving assembly 3 includes a reduction motor 31, a driving bevel gear 32, and a driven bevel gear 33. The reduction motor 31 is fixedly installed on the upper side of the tank body 1. The output end of the reduction motor 31 is fixedly installed with the driving bevel gear 32. The driven bevel gear 33 is fixedly installed on the circumferential side of the hollow tube 6. The driven bevel gear 33 is located between the tank body 1 and the rotary joint 4. The driving bevel gear 32 is meshed and assembled with the driven bevel gear 33. When the reduction motor 31 works, it can rotate the driving bevel gear 32, and the hollow tube 6 is rotated by the engaged driven bevel gear 33. The diameter of the driving bevel gear 32 is smaller than that of the driven bevel gear 33, which has the function of reducing speed and increasing torque.

[0029] Further, an isolation cover 34 is fixedly installed on the upper side of the tank body 1. The driving bevel gear 32 and the driven bevel gear 33 are located inside the isolation cover 34. The isolation cover 34 is provided with through holes for passing through the hollow tube 6 and the output end of the reduction motor 31. The isolation cover 34 plays a role of isolation and protection to prevent sundries from affecting the normal operation of the driving bevel gear 32 and the driven bevel gear 33.

[0030] Specifically, the bottom of the tank body 1 is in the shape of a conical cylinder, which is conducive to the falling of materials. Moreover, the bottom diameter of the hollow spiral blade 9 also gradually decreases, which is conducive to the full contact and discharge of materials.

[0031] Specifically, a socketed clamp 10 is installed between the tank body 1 and the docking pipe 5. The socketed clamp 10 is used to position the docking pipe 5 to prevent the rotary joint 4 and the docking pipe 5 from rotating along with the hollow tube 6.

[0032] Specifically, a feed hopper 2 is fixedly installed at the feed inlet, which is convenient for the conveyor to feed the biological organic fertilizer. A discharge pipe 8 is fixedly installed at the discharge outlet, which is conducive to the discharge of the biological organic fertilizer, so that it falls onto another conveyor and is sent to the next process.

[0033] Specifically, as Figure 4 shown, a thermocouple 11 is installed on the side wall of the discharge pipe 8, which is used to detect the temperature of the biological organic fertilizer discharged from the discharge pipe 8.

[0034] Specifically, a support frame 7 is fixedly installed at the bottom of the tank body 1. The support frames 7 are distributed at the four corners in a rectangular manner to support the tank body 1, so that the discharge pipe 8 is at least 1 meter away from the ground, leaving enough installation space for facilities such as conveyors.

[0035] The reduction motor 31 and the thermocouple 11 are electrically connected to the controller in the external control box through wires and are controlled by the buttons on the control box.

[0036] The working principle of this embodiment:

[0037] During operation, the driving assembly 3 rotates the hollow tube 6 and the hollow spiral blade 9. At the same time, the cooling water tank can generate cold water and pass through the hollow tube 6 and the hollow spiral blade 9 from bottom to top.

[0038] After the well-mixed biological organic fertilizer undergoes the final drying process, it is fed into the hopper 2 through a conveyor, and then falls onto the hollow spiral blade 9 inside the tank body 1. The rotating hollow spiral blade 9 will slow down the downward conveying speed of the biological organic fertilizer, increase the contact time between the biological organic fertilizer and the hollow spiral blade 9, and after cooling, it is discharged from the discharge pipe 8. The thermocouple 11 can detect the temperature of the discharged biological organic fertilizer, which is convenient for the staff to reasonably adjust the rotation speed of the hollow spiral blade 9 and the feeding speed of the input material according to the required discharge temperature.
