Description
Technical Field
[0001] This utility model relates to the technical field of mixing and proportioning devices, specifically a mixing and proportioning device for fly ash and organic fertilizer. Background Technology
[0002] Fly ash is a solid waste from coal-fired power plants. Organic fertilizer, as an important agricultural resource, can alleviate the soil heavyness problem caused by single organic fertilizer or the soil compaction problem caused by single fly ash after being mixed and processed. It is suitable for improving barren and degraded soils, while reducing the environmental pollution caused by the accumulation of waste fly ash.
[0003] Existing technologies use mixing drums with stirring rods to mix fly ash and organic fertilizer. Weight sensors are installed at the hopper of the mixing drum to ensure precise proportioning and uniform mixing of fly ash and organic fertilizer. However, the accumulated fly ash and organic fertilizer can clump together under the influence of moisture. Feeding this clumped fly ash and organic fertilizer directly into the mixing drum slows down the mixing efficiency. Furthermore, some fly ash and organic fertilizer adhere to the discharge point of the hopper during discharge. Over time, this leads to a deviation in the total amount of fly ash and organic fertilizer fed into the mixing drum, affecting the precise proportioning of fly ash and organic fertilizer. To address the shortcomings of existing technologies, we propose a mixing and proportioning device for fly ash and organic fertilizer to solve these problems. Utility Model Content

This device solves the problem of clumping of accumulated fly ash and organic fertilizer under the influence of moisture and other factors. When clumped fly ash and organic fertilizer are directly fed into the mixing drum, the mixing efficiency between the fly ash and organic fertilizer is reduced. Furthermore, some fly ash and organic fertilizer adhere to the discharge part of the feeding hopper during the discharge process. Over time, this leads to a certain deviation in the total amount of fly ash and organic fertilizer fed into the mixing drum, affecting the accurate proportioning of fly ash and organic fertilizer.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0025] This application provides a mixing and proportioning device for fly ash and organic fertilizer, which solves the problem of clumping of accumulated fly ash and organic fertilizer under the influence of moisture and other factors. When clumped fly ash and organic fertilizer are directly fed into the mixing drum, the mixing efficiency between fly ash and organic fertilizer is slowed down. In addition, some fly ash and organic fertilizer adhere to the discharge part of the feeding hopper during the discharge process. Over time, this leads to a certain deviation in the total amount of fly ash and organic fertilizer fed into the mixing drum, affecting the accurate proportion of fly ash and organic fertilizer. This device breaks up the clumped fly ash and organic fertilizer and ensures more complete feeding of fly ash and organic fertilizer.
[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0027] This utility model discloses a mixing and proportioning device for fly ash and organic fertilizer.
[0028] According to the appendix Figure 1-6 As shown, the system includes a mixing drum 1, a stirring rod 2 rotatably disposed inside the mixing drum 1, a drive motor 21 fixedly disposed on the top surface of the mixing drum 1 and fixedly connected to one end of the stirring rod 2, a feeding hopper 3 mounted on the upper part of the mixing drum 1 via a vertical frame, a weighing assembly disposed at the bottom of the feeding hopper 3, and a feeding pipe 4 disposed between the feeding hopper 3 and the mixing drum 1. Valves are provided at the ends of the two sets of feeding pipes 4 near the feeding hopper 3. The two sets of feeding hoppers 3 respectively contain powdered fly ash and organic fertilizer. The weighing assembly includes a support leg 31 fixedly disposed on the bottom surface of the feeding hopper 3, a weight sensor 32 fixedly disposed on the bottom surface of the support leg 31, a junction box 33 disposed on one side of the feeding hopper 3, and a connecting line 34 disposed between the junction box 33 and the weight sensor 32. A screw conveyor 6 is disposed at the bottom of the mixing drum 1.
[0029] Specifically, by opening the valves at the feeding pipes 4 of the two sets of feeding hoppers 3, the feeding pipes 4 are opened, allowing the fly ash and organic fertilizer in the two sets of feeding hoppers 3 to be fed into the mixing drum 1 through the feeding pipes 4 respectively. During this process, the overall weight of the feeding hopper 3 changes according to the change in the total amount of fly ash or organic fertilizer in the feeding hopper 3. At this time, the weight sensor 32 can accurately monitor the weight change of the feeding hopper 3. After the fly ash and organic fertilizer are fed in proportion, the weight sensor 32 transmits the signal to the control terminal connected to it through the junction box 33. Then the control terminal closes the valve, so that the fly ash and organic fertilizer in the two sets of feeding hoppers 3 will not continue to be fed into the mixing drum 1, so that the required amount of fly ash and organic fertilizer is added into the mixing drum 1 in proportion.
[0030] Next, the drive motor 21 is turned on, which drives the stirring rod 2 to rotate. The stirring rod 2 drives the fly ash and organic fertilizer in the mixing drum 1 to mix. After mixing, the mixture is discharged through the screw conveyor 6 set at the bottom of the mixing drum 1.
[0031] See attached document Figure 3-6The mixing drum 1 is equipped with a rolling mechanism inside. The rolling mechanism can compress and break up the clumps of fly ash and organic fertilizer, thereby accelerating the mixing between fly ash and organic fertilizer and making the mixing uniform. The rolling mechanism includes a filter plate 5, which is fixedly installed on the inner wall of the mixing drum 1. The filter plate 5 is located at the upper part of the mixing drum 1, that is, the filter plate 5 is located at the upper part of the mixing position inside the mixing drum 1. The filter plate 5 does not contact the mixing position inside the mixing drum 1. The top surface of the filter plate 5 is rotatably equipped with a pressure roller 52 and a loosening plate 53 connected to the outer wall of one end of the stirring rod 2. The outer wall of the stirring rod 2 is fixedly connected to a connecting frame 51. The pressure roller 52 is rotatably installed on the inner surface of the connecting frame 51. The outer wall of the pressure roller 52 and one end of the loosening plate 53 are in contact with the top surface of the filter plate 5. The pressure roller 52 and the loosening plate 53 are located on both sides of the stirring rod 2.
[0032] See attached document Figure 5-6 The cleaning component 54 is connected to the outer wall of the stirring rod 2. The cleaning component 54 is used to effectively clean the residual material inside the feeding pipe 4. The cleaning component 54 includes two sets of toothed plates 541 slidably disposed on the inner top surface of the mixing cylinder 1, a half gear 542 fixedly connected to the outer wall of the stirring rod 2 and meshing between the two sets of toothed plates 541, and impact rods 543 fixedly disposed at both ends of the two sets of toothed plates 541. The impact rods 543 intermittently collide with the outer wall of the feeding pipe 4. The two sets of toothed plates 541 are fixedly connected to each other. The sides of the two sets of toothed plates 541 with meshing teeth are opposite each other. The top surfaces of the two sets of toothed plates 541 are fixedly connected to a limiting block 544 for limiting their movement. The inner top surface of the mixing cylinder 1 is fixedly connected to a limiting frame 545 for limiting the sliding of the limiting block 544.
[0033] Specifically, when the fly ash and organic fertilizer inside the two sets of feeding hoppers 3 are fed into the mixing cylinder 1 through the feeding pipe 4, the fly ash and organic fertilizer will first fall onto the top surface of the filter plate 5. At this time, the drive motor 21 is turned on to drive the stirring rod 2 to rotate, so that the pressure roller 52 and the loosening plate 53 connected to the stirring rod 2 rotate equally with the stirring rod 2. At this time, under the pressure of the pressure roller 52 and the dispersing action of the loosening plate 53, the clumps of fly ash and organic fertilizer are broken up. The broken fly ash and organic fertilizer powder falls through the filter holes of the filter plate 5 to the mixing position of the mixing cylinder 1. The end of the stirring rod 2 with stirring blades can stir and mix the fly ash and organic fertilizer located in the mixing part of the mixing cylinder 1.
[0034] Simultaneously, when the stirring rod 2 rotates, it can synchronously drive the half gear 542 fixedly connected to it to rotate. The half gear 542 meshes with two sets of toothed plates 541 in sequence. When the half gear 542 meshes with a set of toothed plates 541, it can drive a set of impact rods 543 to impact the outer wall of one end of the feeding pipe 4 that extends into the mixing drum 1. Under the impact of the impact rods 543, the residual fly ash or organic fertilizer inside the feeding pipe 4 is cleaned and discharged, so that the fly ash and organic fertilizer can be fed into the mixing drum 1 more completely, reducing the loss of fly ash and organic fertilizer.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
