[0021] The present invention will be further described below with reference to the accompanying drawings.
[0022] like Figure 1-3The cooling equipment for organic fertilizer production shown includes a cooling box 1 and a cold air generator 2. The cooling box 1 has a door hinged to its front and a feed hopper 10 connected to its upper end. A sealing strip is installed between the door and the cooling box 1. An air supply pipe 3 extending into the cooling box 1 is fixedly connected to the output end of the cold air generator 2. A sealing ring is installed between the air supply pipe 3 and the cooling box 1. An exhaust port is opened at the upper end of the cooling box 1. A regulating valve is fixedly connected to the discharge pipe at the bottom of the feed hopper 10. A feeding shaft 11 is rotatably connected to the feed hopper 10 via a bearing. Several feeding plates 12 are evenly spaced and fixedly connected to the feeding shaft 11. The outer edge of the feeding plates 12 is positioned near the regulating valve. One end of the feeding shaft 11 is connected to a motor base and... The output shaft of the feeding motor is fixedly connected to one side of the feeding hopper 10 by bolts. At least three vibration grooves 5 are movably arranged from top to bottom inside the cooling box 1. The vibration grooves 5 are inclined and the inclination directions of two adjacent vibration grooves 5 are opposite. The bottommost vibration groove 5 extends downward through the through hole opened in the cooling box 1 to the outside of the cooling box 1. The size of the through hole is sufficient to ensure that the vibration groove 5 has enough vibration space. The vibration motor 8 is fixedly connected to the vibration groove 5 by connecting brackets and bolts. The cooling coil 9 is fixedly connected to the bottom of the vibration groove 5 inside the cooling box 1 by connecting plate and bolts. The air supply pipe 3 is connected to the cooling coil 9. Several ventilation holes are opened at the bottom of the vibration groove 5.
[0023] It should be noted that, in this embodiment, in order to avoid the material moving too fast in the vibrating trough 5, resulting in a short contact time between the material and the cold air and a poor cooling effect, the inclination angle of the vibrating trough 5 is 5-20 degrees; in order to ensure smooth material feeding, the upward-inclined end of the vibrating trough 5 is the input end and the downward-inclined end is the output end. The input end of the lower vibrating trough 5 is directly below the output end of the upper vibrating trough 5, so that the material can be smoothly connected; in order to facilitate the control of cold air delivery, a valve 4 is connected to the air supply pipe 3.
[0024] The working process of this embodiment is as follows: When cooling organic fertilizer granules, the material is transported by a conveyor belt. The output end of the conveyor belt is located directly above the feed hopper 10, conveying the material into the feed hopper 10. The operator starts the feeding motor, which drives the feeding shaft and feeding plate to rotate and continuously move the material to avoid blockage of the discharge port. The regulating valve is opened to a certain degree, allowing the material to fall into the uppermost vibrating trough 5. Simultaneously, the vibrating motor 8 is started, which drives the material downward. At the same time, the valve 4 is opened and the cold air generator 2 is started. The air pump in the cold air generator 2 blows low-temperature air into the air supply pipe 3 and into the cooling coil 9. The cold air is sprayed out from the cooling coil 9 and passes through the ventilation holes at the bottom of the vibrating trough 5 to cool the organic fertilizer. The cold air is discharged from the exhaust port. With the continuous vibration of the vibrating trough 5, the organic fertilizer granules can be turned over for cooling, and the organic fertilizer can be continuously vibrated from the upper vibrating trough 5 to the lower vibrating trough 5. Finally, the material is discharged from the lowermost vibrating trough 5 for subsequent operations.
[0025] To facilitate gas exhaust after cooling and simultaneously recover waste heat, thus saving energy, a gas collection hood 21 is fixedly connected to the top of the cooling tank 1 via connecting rods and bolts. An exhaust pipe 19, penetrating the exhaust port, is fixedly connected to the upper end of the gas collection hood 21. A sealing ring is installed between the exhaust pipe 19 and the exhaust port. The other end of the exhaust pipe 19 is connected to an exhaust fan 20. The output end of the exhaust fan 20 is connected to a heat exchanger 22 via a pipe. The other end of the heat exchanger 22 is connected to an air outlet. A circulating liquid pipe is also fixedly connected inside the heat exchanger 22. It should be noted that in this embodiment, during operation, the circulating liquid pipe of the heat exchanger 22 uses circulating water as hot water for normal production in the workshop.
[0026] The working process of this embodiment is as follows: During the cooling process, the exhaust fan 20 is started and operated. Under the action of the exhaust fan 20, the heated gas is drawn out from the exhaust pipe 19 and enters the heat exchanger 22 to preheat the circulating liquid and utilize the circulating liquid.
[0027] To prevent materials from falling outside the vibrating trough 5 during the falling process, a baffle plate 18 is fixedly connected to the higher side of the vibrating trough 5.
[0028] To facilitate size adjustment and prevent overfeeding and blockage, the regulating valve includes a slide plate 13. Slide grooves are provided on both sides of the feed pipe, and the slide plate 13 is slidably connected to the slide grooves. One end of the slide plate 13 passes through the feed pipe, and a connecting frame 14 is fixedly connected to the outside of the feed pipe. One end of the first adjusting screw 15 is threadedly connected to the connecting frame 14 and rotatably connected to the end of the slide plate 13. The other end of the first adjusting screw 15 is fixedly connected to a first adjusting turntable 16. A retaining sleeve 29 is fixedly connected to the end of the slide plate 13, and a locking block 30 is fixedly connected to the end of the first adjusting screw 15, which rotatably engages with the retaining sleeve 29.
[0029] The working process of this embodiment is as follows: when the regulating valve is opened, the first regulating turntable 16 is grasped and the first regulating screw 15 is rotated to drive the insert plate 13 to move, so as to adjust the opening degree of the insert plate 13.
[0030] To ensure that the material passes through the vibrating trough 5 evenly during vibration and to avoid excessive material flowing downwards which would reduce the cooling effect, at least one material distributor is fixedly connected to the vibrating trough 5. The material distributor includes a material distributor plate 26 and a support frame 24. Grooves 25 are correspondingly opened on both sides of the vibrating trough 5. The material distributor plate 26 is slidably locked in the groove 25. The support frame 24 is fixedly connected to the vibrating trough 5. The lower end of the second adjusting screw 27 is threadedly connected to the support frame 24 and rotatably locked to the upper end of the material distributor plate 26. A second adjusting turntable 28 is fixedly connected to the upper end of the second adjusting screw 27. The material distributor plate 26 has a rotating groove. The end of the second adjusting screw 27 is rotatably locked in the rotating groove.
[0031] The working process of this embodiment is as follows: Before cooling the organic fertilizer, the second adjusting turntable 28 is rotated to drive the second adjusting screw 27 to rotate, thereby adjusting the gap between the uniform material plate 26 and the bottom of the vibrating trough 5, controlling the amount of organic fertilizer passing through the vibrating trough 5 during vibration, and ensuring that the uniform material plate 26 allows the organic fertilizer to pass through evenly, avoiding the accumulation of organic fertilizer. During use, the opening of the uniform material plate 26 can be adjusted adaptively in conjunction with the opening of the adjusting valve to ensure that the organic fertilizer is spread evenly.
[0032] To facilitate the vibration feeding of the vibration trough 5, an installation block 6 is fixedly connected to the inner wall of the cooling box 1, and the bottom of both sides of the vibration trough 5 is connected to the upper end of the installation block 6 by springs 7.
[0033] To ensure that the cold air is sprayed out evenly to cool the material, several upward-facing air diffusers 17 are fixedly connected to the cooling coil 9 at even intervals.
[0034] The working process of this embodiment is as follows: During cooling, cold air enters the cooling coil 9 and is evenly sprayed out from the diffuser 17, increasing the contact area between the cold air and the vibration groove 5 and improving the cooling effect.
[0035] To ensure that cold air enters the cooling coil 9 smoothly, the air supply duct 3 is fixedly connected to the lowermost cooling coil 9. Adjacent cooling coils 9 are connected by a connecting pipe 23, allowing cold air to enter the upper cooling coil 9 from the lower coil through the connecting pipe 23. It should be noted that in this embodiment, when there are many vibration grooves 5, a booster pump can be fixedly connected to the air supply duct 3 to increase the operating rate of the cold air and ensure better cooling effect.
[0036] It should be noted that in this embodiment, the cold air generator 2 is an existing device, which has its own air pump and can set the air outlet temperature. During use, the air outlet temperature can be adjusted according to the cooling effect of the material to avoid excessive energy consumption.
[0037] The working principle of this embodiment is as follows:
[0038] When the organic fertilizer granules need to be cooled after drying, the material is fed into the feed hopper 10 by a conveyor belt. The opening of the regulating valve is adjusted, and the feeding motor is started to drive the feeding shaft 11 and feeding plate 12 to rotate, so as to avoid blockage during material flow. After the material enters the vibrating trough 5, the vibrating motor 8 is started to run, which drives the vibrating trough 5 to vibrate and feed the material. At the same time, the cold air generator 2 is started, and cold air is sprayed from the cooling coil 9 to the vibrating trough 5 to cool the organic fertilizer granules. The cooled hot air enters the heat exchanger for heat exchange and can be reused.
