Description

Technical Field

[0001] The invention relates to a fast-filling anti-caking and highly stable compost degradation container, belonging to the field of compost detection containers. Background Art

[0002] The biodegradable materials industry is an emerging industry that is developing very rapidly. Due to its high production costs, some businesses take advantage of the similarities in appearance between ordinary plastic products and biodegradable plastic products, engage in false advertising, and confuse the fake with the real, aggravating the adverse effects of "white pollution" on the environment and restricting the rapid and healthy development of the biodegradable materials industry.

[0003] The detection and certification of degradable performance is a key means to determine whether degradable material products are compliant. The core component of the biodegradable material biodegradability tester is the compost container. The degradable performance test is actually an aerobic composting process. Aerobic composting is the process of aerobic bacteria absorbing, oxidizing and decomposing waste under good ventilation conditions and sufficient oxygen. The biodegradation rate is determined by collecting the mass of carbon dioxide produced by microbial decomposition of degradable materials in the compost container. In the test, 2-5L narrow-mouthed high-boron glass bottles are usually used as compost containers, but the mouth of the glass bottle is small, and it is difficult to fill the test materials. When replacing the compost container, it is necessary to disconnect the air inlet, air outlet and water supply pipeline of the gas path, etc., and the steps are relatively cumbersome; the bottom air pipe is a single tube and a single port, and the air flow cannot be evenly diffused, which is easy to cause the compost material to compact and is easily blocked by mud. The safety is poor and the experiment cannot be completed in a continuous one-pot method. Summary of the invention

[0004] The present invention provides a fast-filling anti-caking high-stability compost degradation container, wherein the upper and lower tank bodies are arranged as structures movably connected to the secondary holes through splicing protrusions, and both are straight-cylinder structures, which facilitates the filling of test materials, and the operation is simple, convenient, efficient, and has good stability; by improving the bottom air inlet pipe, the air hole layout of the bottom air inlet pipe is changed, the blockage of the air inlet pipe is reduced, and the uniform diffusion of the air flow is achieved; the stirring motor is effectively protected, and it is ensured that the stirring can continue to work stably for a long time under high temperature and high humidity conditions; by improving the stirring blades, the stirring range is significantly increased, and the detection efficiency and safety are improved.

[0005] It is convenient to load the tank, and the problem of quickly filling the compost is solved through the design of the compost container.

[0006] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows:

[0007] A fast-filling, anti-caking, high-stability composting degradation container comprises an upper tank body, a bottom air inlet pipe, a lower tank body, a top cover, a stirring motor, a protective cover and a stirring rod;

[0008] The upper tank body is a straight cylinder structure with an open top and a sealed bottom. A mounting hole is provided at the bottom of the upper tank body. The mounting hole is formed by splicing a primary hole and a secondary hole that are connected to each other and interpenetrate each other, and the aperture of the primary hole is smaller than that of the secondary hole.

[0009] The bottom air inlet pipe includes a connecting ring, an inner pipe and an outer pipe; the connecting ring is a ring-shaped structure, the inner pipe is a tubular structure with both ends open, the inner pipe is located on the inner side of the inner ring of the connecting ring and is connected to the inner ring of the connecting ring, the length of the inner pipe below the connecting ring is not zero, and forms a connecting section; the outer pipe is a tubular structure with one end sealed and the other end open, the open end of the outer pipe is downwardly sleeved on the outer periphery of the inner pipe, the open end of the outer pipe is connected to the connecting ring, and there is a gap between the top and side wall of the inner pipe and the top and side wall of the outer pipe as a buffer cavity; the side wall of the outer pipe is provided with air holes distributed in the axial direction and the circumferential direction;

[0010] The bottom air inlet pipe is vertically arranged at the bottom of the inner side of the upper tank body, and the connecting section is plugged into the first-level hole;

[0011] The lower tank body is a straight cylinder structure with sealed ends at the top and bottom. A splicing protrusion is provided on the top of the lower tank body, and an air inlet path communicating with the interior of the lower tank body is provided on the splicing protrusion. The splicing protrusion matches the secondary hole. The upper tank body is placed on the top of the lower tank body, and the splicing protrusion matches and is inserted into the secondary hole. The air inlet path on the splicing protrusion communicates with the inner tube. A water inlet pipe is provided on the side wall of the top of the lower tank body, and an air inlet hole is provided at the bottom of the lower tank body.

[0012] The top cover is movably connected to the top of the upper tank body; a sampling hole, a sensor connection hole and an air outlet are arranged on the top of the top cover, a movable cover is arranged on the sampling hole, and an air outlet pipe is connected to the outer side of the air outlet;

[0013] The stirring motor is installed on the cover body, the rotating shaft of the stirring motor extends into the interior of the upper tank body, and the protective cover is arranged on the periphery of the stirring motor;

[0014] The stirring rod is connected to the rotating shaft of the stirring motor, and a gap is left between the bottom of the stirring rod and the top of the bottom air inlet pipe. One or more stirring blades with the same structure are arranged around the bottom of the stirring rod, and each pair of stirring blades includes an upturned stirring blade and a downturned stirring blade that are relatively arranged. One end of the upturned stirring blade and the downturned stirring blade are connected to the bottom periphery of the stirring rod, and the other end is arc-shaped. Stirring holes are arranged at one end of the arc of the upturned stirring blade and the downturned stirring blade. The upturned stirring blade is bent upward and forms an angle of 50 to 80 degrees with the vertical direction. The downturned stirring blade is bent downward and forms an angle of 50 to 80 degrees with the vertical direction.

[0015] The upper tank body and the lower tank body are movably connected through matching secondary holes and splicing protrusions. After the reactants are filled in the upper tank body, it can be quickly connected to the lower tank body, which not only improves the work efficiency but also improves the stability of the composting tank body. It is simple, safe and reliable.

[0016] The above bottom air inlet pipe effectively solves the problems of uneven air intake and easy blockage at the bottom of the compost container; there are air holes distributed along the axial and circumferential directions on the side wall of the outer pipe, which means that there are multiple (more than three) air holes distributed along the axial direction (in the height direction) on the side wall of the outer pipe, and there are also multiple (more than three) air holes distributed along the circumferential direction; during use, the air flow enters through the bottom of the inner pipe, flows out from the top of the inner pipe, enters the buffer chamber, and then is dispersed into the reactants through the air holes distributed on the side wall of the outer pipe; this application changes the air hole layout of the bottom air inlet pipe, and the air holes are distributed on the surface of the outer pipe, which can not only prevent the air inlet pipe from being blocked, but also achieve the purpose of uniform gas dispersion, reduce the possibility of compost compaction, reduce safety accidents, facilitate the realization of continuous one-pot tests, and improve the test efficiency and accuracy.

[0018] The above-mentioned upwardly curved stirring blades bend upward to cover the height of the stirring shaft, and the downwardly curved stirring blades bend downward to cover the height of the bottom air inlet pipe. This can ensure the all-round agitation of the materials. The free ends of the upwardly curved stirring blades and the downwardly curved stirring blades are designed as arc-shaped, which is beneficial to the smooth progress of material stirring. With the design of the stirring holes, the materials can pass through the stirring holes to form stirring, which improves the uniformity of stirring and also avoids the jamming phenomenon of the overall agitation of large pieces of materials, improving the safety of stirring.

After the loading is completed, the upper tank body and the lower tank body are movably connected through the splicing protrusions and the secondary holes, which is fast and stable; air is introduced into the bottom of the lower tank body, and the air and water vapor in the lower tank body will enter from the bottom of the inner pipe under the action of pressure, flow out from the top of the inner pipe, enter the buffer chamber, and then be dispersed into the reactants through the air holes distributed on the side wall of the outer pipe; the stirring motor can be started according to the experimental needs. The setting of the anti-moisture protection cover effectively isolates water vapor, ensures that the stirring works continuously and stably for a long time under high-temperature and high-humidity conditions. Through the design of the upwardly curved stirring blades and the downwardly curved stirring blades, the stirring range is significantly expanded, compaction is avoided, and the uniformity of the materials, the safety and accuracy of the test are improved.
