Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, specifically a reciprocating aerobic fermentation mixer for solid waste. Background Technology

[0002] Solid waste aerobic fermentation mixer is a device used in public toilets for the fermentation treatment of fecal waste. It thoroughly mixes fecal waste, auxiliary materials, and microbial agents, and oxygenates the mixed materials to increase the oxygen contact between the fermentation materials and the microbial agents, thus meeting the survival requirements of the microbial agents and promoting their reproduction and the degradation reaction of the fecal waste.

[0003] Existing mechanical mixing methods mainly include two types: fixed mixing and reciprocating mixing. Fixed mixing involves the mixing motor and shaft being fixed at one end and cannot be moved. However, due to the limited length of the shaft, it is unsuitable for excessively long toilets. If the toilet is too long, the mixing pump will deform under its own weight, affecting the rotation of the shaft. However, an excessively long shaft requires a larger motor to provide greater torque, increasing construction costs and energy consumption. Reciprocating mixing, while solving the problems of fixed mixing, also suffers from issues such as the mixing chain being in constant contact with fecal matter, leading to severe corrosion, chain hardening and deformation, and eventual breakage. Furthermore, the chain stretches over time, making it prone to slippage. Additionally, some mixing units may shake during operation when the fermentation of fecal matter is uneven, causing the center of gravity to shift and potentially leading to derailment during reciprocating movement. The heavy weight of the equipment and limited space in the operating environment also make maintenance difficult.

[0004] To address the issues of inadequate and uneven mixing, as well as the limited automation of fixed and reciprocating mixing equipment, a reciprocating aerobic fermentation mixer for solid waste is proposed. Utility Model Content

[0012] The cable drag chain includes a drag chain bracket fixedly installed on the side of the machine side plate and a drag chain structure slidably connected to the outside of the drag chain bracket.

[0013] The automatic control system includes a control cabinet located on the side of the frame and a mounting structure located at the bottom of the control cabinet.

[0014] Furthermore, the passive gears on the outer sides of the active walking shaft and the passive walking shaft are connected by a transmission chain, and the active gear on the outer side of the active walking shaft is connected to the output shaft of the walking motor by an active walking chain.

[0015] Furthermore, the two ends of the active walking shaft and the passive walking shaft are respectively embedded in the reserved mounting shaft positions at both ends of the side of the machine side plate and are rotatably connected to the machine side plate through bearings.

[0016] Furthermore, the two ends of the stirring shaft are embedded in the reserved mounting positions at the bottom of the machine side plate, and a transmission gear and stirring chain are provided on the outer side of one end of the stirring shaft located on the machine side plate.

[0021] Compared with the prior art, this utility model provides a reciprocating aerobic fermentation mixer for solid manure, which has the following beneficial effects:

[0022] 1. This reciprocating solid manure aerobic fermentation mixer uses a stirring motor to drive the stirring chain, which in turn transmits power to the stirring shaft. The rotation of the stirring shaft causes the stirring teeth to penetrate deep into the material. When the stirring shaft rotates, the stirring teeth act like a plow, turning the material up from the bottom and scattering it to one side or in the middle. This allows the material to be continuously turned and mixed in the fermentation chamber. During this process, the material comes into full contact with the air, which helps the fermentation activity of aerobic microorganisms and makes the temperature and humidity of the material more evenly distributed in the fermentation chamber.

[0023] 2. This reciprocating solid waste aerobic fermentation mixer rotates by starting a walking motor. The rotation of the walking motor drives the active walking chain to transmit power to the active walking shaft. The active walking shaft drives the passive walking shaft to rotate synchronously through the transmission chain, which in turn drives the outer wheels to rotate, thus moving the device. This allows for the mixing of materials at various locations within the tunnel, thereby improving work efficiency and solving the problems of inadequate and uneven mixing, as well as the limited automation level, that occur with fixed and reciprocating mixing equipment.

[0033] 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.

[0034] Please see Figures 1 to 8 In this embodiment, a reciprocating solid manure aerobic fermentation mixer includes a frame 02, a walking system 01 at the bottom of the frame 02, a power transmission system 03 on the inner side wall of the frame 02, a stirring working component 04 on the outer side of the power transmission system 03, a bacteria addition system 05 on the side of the frame 02, a cable drag chain 06 on the side wall of the frame 02, and an automatic control system 07 on the side wall of the frame 02.

[0041] In this example, the automatic control system 07 includes a control cabinet 701 located on the side of the frame 02 and a mounting structure 702 located at the bottom of the control cabinet 701. By adding an intelligent control system inside the control cabinet 701, the fermentation agitator is controlled to work within a fixed time period, and the number of agitations is adjusted according to different seasons and times, allowing for precise control of the agitator's start-up and shutdown times and stop positions.

[0046] By setting a chain sleeve 203 to wrap the outside of the mixing chain 305, it is sealed and protected from corrosion by fecal matter.

[0047] In this example, the mounting hardware 403 is spirally distributed on the outside of the stirring shaft 401, and the stirring teeth 402 are L-shaped plate structures and are fixedly mounted on the side of the mounting hardware 403 by connecting mounting bolts 404.

[0048] The stirring teeth 402 are fixed to the stirring shaft by installing the fastener 403, which facilitates disassembly and replacement, ensures the stirring effect, and optimizes the structural parameters and arrangement of the throwing blades to minimize the impact vibration of the throwing blades and improve the uniformity of stirring.

[0050] In this example, the side of the mounting structure 702 and the side of the frame 02 are fixedly mounted.

[0051] The working principle of the above embodiments is as follows:

[0052] The stirring motor 302 drives the stirring chain 305 to rotate, transmitting power to the stirring shaft 401. The rotation of the stirring shaft 401 causes the stirring teeth 402 to penetrate deep into the material. When the stirring shaft 401 rotates, the stirring teeth 402 act like a plow, turning the material up from the bottom and scattering it to one side or in the middle, so that the material is constantly turned over and mixed in the fermentation chamber. During this process, the material comes into full contact with the air, which helps the fermentation activity of aerobic microorganisms and makes the temperature and humidity of the material more evenly distributed in the fermentation chamber.

[0053] In addition, by starting the walking motor 301 to rotate, the rotation of the walking motor 301 drives the active walking chain 303 to transmit power to the active walking shaft 101. The active walking shaft 101 drives the passive walking shaft 102 to rotate synchronously through the transmission chain, which in turn drives the outer traveling wheel 106 to rotate, thereby realizing the movement of the device, thereby realizing the mixing of materials in various locations in the tunnel, thus improving the work efficiency.
