Description

Technical Field

[0001] This utility model relates to the field of static fermentation composting tank technology, and in particular to a static fermentation composting tank. Background Technology

[0002] Composting is a process that uses plant and animal remains and excrement containing fertilizer components, mixed with soil and minerals, and piled up under high temperature and high humidity conditions. Through fermentation, decomposition by microorganisms, organic fertilizer is produced.

[0003] A fermentation composting tank is a device used for the aerobic fermentation of organic waste. It transforms organic matter by turning, ventilating, and composting it in a closed or semi-closed tank. It is mainly used to convert organic waste (such as livestock and poultry manure, crop straw, etc.) into organic fertilizer through aerobic fermentation.

[0004] While the above technologies achieve fermentation of organic waste, the oxygen demand of microorganisms varies with the stage during actual use: the oxygen demand is high during the initial heating period, requiring the oxygen vent to be opened to increase ventilation; a stable oxygen supply is needed during the middle high-temperature period; and the oxygen demand decreases during the later maturation period, requiring the vent to be closed to avoid energy waste. This makes the technology less convenient to use. Therefore, a static fermentation composting tank is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a static fermentation composting tank, which aims to solve the problem of the variation of microbial oxygen demand in the existing technology with different stages: high oxygen demand in the initial heating period, requiring opening the oxygen vent to increase ventilation; stable oxygen supply required in the middle high-temperature period; and decreased oxygen demand in the later maturation period, where closing the vent can avoid energy waste.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a static fermentation composting tank, including a composting box, a box cover slidably connected to the top of the composting box, a drain pipe fixedly connected to the outer wall of the composting box, a heating component provided on the outer wall of the composting box, and an oxygen port opening and closing component provided on the outer wall of the composting box.

A baffle is fixedly connected to the outer wall of the fixed plate. A rotating handle is fixedly connected to the outer wall of the baffle. A groove is provided on the outer wall of the fixed base. A disc is fixedly connected to the front end of the rotating shaft.

[0008] As a further description of the above technical solution:

[0009] One end of the spring is fixedly connected to the rear wall of the first ring, and the other end of the spring is fixedly connected to the front end of the second ring.

[0011] The rear wall of the rotating shaft is fixedly connected to the outer wall of the compost bin, and the outer wall of the baffle is rotatably connected to the inside of the groove.

[0012] As a further description of the above technical solution:

[0013] The rear wall of the mounting base is fixedly connected to the outer wall of the compost bin.

[0014] As a further description of the above technical solution:

[0015] The rear wall of the second ring is fixedly connected to the outer wall of the compost bin.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 An embodiment of this utility model is provided: a static fermentation composting tank, including a composting box 1, a box cover 2 that is slidably connected to the top of the composting box 1 and can be opened and closed by sliding, a drain pipe 3 for discharging excess leachate produced by fermentation is fixedly connected to the outer wall of the composting box 1, a heating component 4 is provided on the outer wall of the composting box 1, and an oxygen port opening and closing component 5 is provided on the outer wall of the composting box 1.

[0033] The oxygen inlet opening and closing assembly 5 includes a rotating shaft 51 and a fixed base 59. A first ring 52 is fixedly connected to the outer wall of the rotating shaft 51 and can rotate synchronously with the rotating shaft 51. A second ring 54 is elastically connected to the rear wall of the first ring 52 through a spring 53. A fixed plate 55 is rotatably connected to the outer wall of the rotating shaft 51 for connecting the rotating shaft 51 and the baffle 57. The baffle 57 is fixedly connected to the outer wall of the fixed plate 55. A handle 58 for easy manual operation of rotating the baffle 57 is fixedly connected to the outer wall of the baffle 57. A groove 510 is opened on the outer wall of the fixed base 59 to cooperate with the baffle 57 to form a sealing structure. A disc 56 is fixedly connected to the front end of the rotating shaft 51. One end of the spring 53 is fixedly connected to the rear wall of the first ring 52, and the other end of the spring 53 is fixedly connected to the front end of the second ring 54. The top cover 2 can be slidably opened and closed for easy material loading and unloading. When it is necessary to adjust the oxygen content of the composting environment, this is achieved by operating the oxygen port opening and closing component 5: rotating the handle 58 causes the baffle 57 to rotate within the groove 510 of the fixed seat 59. At this time, the rotating shaft 51 rotates accordingly, causing the first ring 52 fixed on the rotating shaft 51 to rotate synchronously and stretch the spring 53. The elastic force of the spring 53 can achieve stable positioning of the baffle 57, thereby controlling the opening and closing degree of the oxygen port and adjusting the airflow inside and outside the composting box 1.

[0034] Reference Figures 2-4 The rear wall of the rotating shaft 51 is fixedly connected to the outer wall of the composting bin 1, thus fixing the oxygen inlet opening and closing assembly 5 to the composting bin 1. The outer wall of the baffle 57 is rotatably connected to the inside of the groove 510. The rear wall of the fixing seat 59 is fixedly connected to the outer wall of the composting bin 1. The rear wall of the second ring 54 is fixedly connected to the outer wall of the composting bin 1. The heating assembly 4 includes a mounting frame 41 for carrying the heating wire 43. The rear wall of the mounting frame 41 is fixedly connected to a sliding strip 42 that cooperates with the slide rail 44 to achieve the sliding of the mounting frame 41. The inside of the mounting frame 41 is fixedly connected to a device that generates heat when energized. The heating element 43 heats the composting bin 1. A slide rail 44 is fixedly connected to the outer wall of the composting bin 1. The outer wall of the sliding bar 42 is slidably connected to the inside of the slide rail 44. Two sets of mounting frames 41 are provided to improve the heating uniformity of the composting bin 1. The two sets of mounting frames 41 are mirror-distributed along the central axis of the composting bin 1. The mounting frames 41 are adjusted in position by sliding the sliding bar 42 in the slide rail 44. The heating element 43 inside generates heat when it works. The two sets of symmetrically distributed mounting frames 41 can make the composting bin 1 heat more evenly, which helps to maintain the appropriate temperature required for composting.

[0035] Working principle: During use, the top cover 2 can be slidably opened and closed, facilitating the addition and removal of dry materials. When it is necessary to adjust the oxygen content of the composting environment, this is achieved by operating the oxygen port opening and closing component 5: rotating the handle 58 causes the baffle 57 to rotate within the groove 510 of the fixed seat 59. At this time, the rotating shaft 51 rotates accordingly, causing the first ring 52 fixed on the rotating shaft 51 to rotate synchronously and stretch the spring 53. The elastic force of the spring 53 can achieve stable positioning of the baffle 57, thereby controlling the opening and closing degree of the oxygen port and adjusting the air circulation inside and outside the composting box 1. The mounting frame 41 is adjusted in position by sliding the sliding bar 42 within the slide rail 44. The heating wire 43 inside generates heat when working. The two sets of symmetrically distributed mounting frames 41 can make the composting box 1 heat more evenly, which helps to maintain the appropriate temperature required for composting.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
