Description

Technical Field

[0001] This utility model relates to the technical field of silkworm excrement cleaning and recycling devices, and in particular to a silkworm excrement cleaning and recycling device. Background Technology

[0002] Silkworm excrement is the dried feces of silkworm larvae, also known as raw silkworm excrement, late silkworm excrement, or silkworm sand. It is rich in nutrients but may also contain impurities, undigested mulberry leaf fragments, and potential pathogens. Therefore, before use, silkworm excrement needs to be cleaned and recycled using a silkworm excrement cleaning and recycling device to ensure its quality and safety.

[0003] Chinese patent document CN221493171 U discloses a silkworm excrement collection device, relating to the field of silkworm excrement technology. This utility model includes a base and a base plate. The top of the base is fixedly connected to the bottom of the base plate, and a collection and drying box is fixedly connected to the top of the base plate. A collection and filtration device is installed on the top of the collection and drying box. The collection and filtration device includes a top cover, the bottom of which is fixedly connected to the top of the collection and drying box. An inlet is opened on the top of the top cover, and a hollow circular plate is fixedly connected to the top of the top cover. This utility model achieves the collection and filtration of silkworm excrement through the interaction of the rotational force of the dispersion plate and the hollow circular plate, rotating rod, and filter plate components inside the collection and filtration device. During the collection process, the silkworm excrement is initially filtered and dispersed, which helps improve its quality and usability, helps to evenly disperse the excrement, and effectively prevents its accumulation, making subsequent processing or utilization more convenient.

[0004] The existing technology has the following problems:

[0005] Although the above-mentioned utility model can prevent the accumulation of silkworm excrement, the silkworm excrement also contains impurities. It is necessary to crush the silkworm excrement to separate the impurities from the silkworm excrement, and to directly pour the silkworm excrement onto the top of the filter plate. The lack of a driving source makes the filtration effect slow. Utility Model Content

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-5As shown, a silkworm excrement cleaning and recycling device includes a support frame 1, a lower tank 2 fixedly connected to the upper part of the support frame 1, an upper tank 3 abutting the upper surface of the lower tank 2, a feeding pipe 4 fixedly connected to the left side of the outer periphery of the upper tank 3, a discharge pipe 5 fixedly connected to the lower surface of the lower tank 2, and a crushing mechanism 6 movably connected to the middle of the inner cavity of the upper tank 3.

[0027] The crushing mechanism 6 includes a motor 61, the lower surface of which is fixedly connected to the middle of the upper surface of the upper tank 3. A rotating rod 62 is fixedly connected to the output end of the motor 61. Four connecting rods 63 arranged in a ring are fixedly connected to the lower part of the outer periphery of the rotating rod 62. Two connecting plates 64 are fixedly connected to the lower surface of the connecting rods 63. A scraper 68 is fixedly connected to the lower part of the rotating rod 62. A crushing roller 65 is rotatably connected to the lower part of the two connecting plates 64 on opposite sides. A crushing screen plate 66 is fixedly connected to the middle of the inner cavity of the upper tank 3. A guide plate 8 is fixedly connected to the upper surface of the crushing screen plate 66. A guide tube 67 is fixedly connected to the lower surface of the crushing screen plate 66.

[0028] It should be noted that when motor 61 starts, it drives connecting rod 63 and connecting plate 64 to rotate via rotating rod 62. The rotation of connecting rod 63 causes the crushing roller 65 to perform a crushing action above the crushing screen plate 66, effectively crushing the silkworm excrement. The rotation of rotating rod 62 also causes scraper 68 to rotate. Scraper 68 rotates on the bottom surface of crushing screen plate 66, not only assisting the crushing process but also preventing material from accumulating on the screen plate, ensuring that the material passes smoothly through the screen. Crushing screen plate 66 not only performs a screening function, but its upper surface guide plate 8 can guide the silkworm excrement to be evenly distributed below crushing roller 65, improving crushing efficiency. Guide tube 67 is used to guide the fine particles or liquids after screening to flow downwards, further promoting material separation.

[0029] like Figure 2 As shown, four studs 10 arranged in a ring are fixedly connected to the upper surface of the lower tank 2. The studs 10 penetrate the lower part of the upper tank 3. Nuts 11 are threadedly connected to the outer periphery of the upper part of the studs 10. The lower surface of the nuts 11 abuts against the upper surface of the lower outer periphery of the upper tank 3. A vibration mechanism 7 is movably connected to the upper part of the inner cavity of the lower tank 2.

[0030] It should be noted that the stud 10 and nut 11 work together to facilitate the detachable connection between the upper tank 3 and the lower tank 2, which is convenient for equipment maintenance and cleaning.

[0031] like Figure 4 As shown, the vibration mechanism 7 includes a vibrating screen plate 74. The outer periphery of the vibrating screen plate 74 is slidably connected to the upper part of the inner side of the lower tank 2. A second motor 71 is fixedly connected to the left part of the outer periphery of the lower tank 2. A rotating shaft 72 is fixedly connected to the output end of the second motor 71. Four eccentric wheels 73 are fixedly connected to the outer periphery of the rotating shaft 72.

[0032] It should be noted that the vibration mechanism 7 drives the rotating shaft 72 to rotate via the motor 71, which in turn drives the eccentric wheel 73 to rotate. The irregular shape of the eccentric wheel 73 causes the vibrating screen plate 74 to vibrate up and down, which helps to loosen larger particles or clumps of silkworm excrement stuck on the screen and allow them to continue to pass through the screen, thus enhancing the screening effect.

[0033] like Figure 4 and Figure 5 As shown, four sliders 75 arranged in a ring are fixedly connected to the outer periphery of the vibrating screen plate 74, and four sliding grooves 76 arranged in a ring are opened in the upper part of the inner cavity of the lower tank 2, with the sliders 75 slidably connected inside the sliding grooves 76.

[0034] It should be noted that the cooperation between the slider 75 and the groove 76 ensures the stability of the vibrating screen plate 74 during vibration, preventing it from shifting or shaking excessively.

[0035] like Figure 4 As shown, the left and right ends of the rotating shaft 72 are rotatably connected to the left and right sides of the middle of the lower tank body 2, respectively, and the upper surfaces of the outer sides of the two eccentric wheels 73 away from the middle of the rotating shaft 72 abut against the lower surface of the vibrating screen plate 74.

[0036] It should be noted that the rotating shaft 72 rotates in the middle of the lower tank 2 to ensure the stability of the rotating shaft 72.

[0037] like Figure 3 As shown, a heating coil 9 is fixedly connected to the upper surface of the inner cavity of the upper tank 3, and the outer periphery of the guide plate 8 is fixedly connected to the inner side of the upper tank 3.

[0038] It should be noted that the heating coil 9 is used to preheat or dry the silkworm excrement inside the upper tank 3, which helps improve the fluidity of the excrement, making it easier to crush and screen. Preheating also promotes the evaporation of any moisture that may be present in the excrement, reducing energy consumption and environmental pollution in subsequent processing.

[0039] like Figure 3 As shown, the lower surface of the scraper 68 is rotatably connected to the bottom surface of the inner cavity of the crushing screen plate 66, and the outer periphery of the crushing roller 65 is slidably connected to the bottom surface of the inner cavity of the crushing screen plate 66.

[0040] It should be noted that the lower part of the scraper 68 slides above the crushing screen plate 66, which can clean and scrape off the residue adhering to the bottom surface of the crushing screen plate 66, helping to prevent material accumulation, maintain the unobstructed flow of the screen plate, and thus improve screening efficiency and equipment operating stability. The outer periphery of the crushing roller 65 slides above the crushing screen plate 66 and is used to crush and break the silkworm excrement, allowing the silkworm excrement to pass through the screen.

[0041] The working principle of this utility model is as follows: First, silkworm excrement is fed into the upper tank 3 through the feeding pipe 4. The excrement enters the crushing screen plate 66 through the guide plate 8. The heating coil 9 is activated to heat the excrement. The motor 61 drives the rotating rod 62 to rotate, which in turn drives the connecting rod 63 to rotate. The rotation of the connecting rod 63 causes the connecting plate 64 to drive the crushing roller 65 to crush the excrement inside the crushing screen plate 66. While the rotating rod 62 is rotating, the scraper 68 cleans the crushing screen plate 66 to prevent the excrement from clogging and accumulating. After screening, the excrement falls into the vibrating screen plate 74. The motor 71 drives the rotating shaft 72 to rotate, causing the eccentric wheel 73 to rotate around the axis of the rotating shaft 72. The rotation of the eccentric wheel 73 causes it to reciprocate on the vibrating screen plate 74 above, screening the excrement inside. After screening, the excrement is output through the discharge pipe 5. After prolonged use, the upper tank 3 is opened to clean the vibrating screen plate 74.

[0042] 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.
