Description

Technical Field

[0001] This utility model relates to the technical field of kitchen waste treatment equipment, and in particular to a kitchen waste decomposition tank with an insulated jacket. Background Technology

[0002] Food waste decomposition tanks are currently an effective device for treating organic waste. They typically utilize microorganisms to degrade food waste under suitable conditions. In this biochemical degradation process, temperature is one of the key factors affecting microbial activity and decomposition efficiency. To maintain a high decomposition rate, the temperature inside the decomposition tank needs to be kept within a relatively stable and optimal range.

[0003] However, during operation, the heat generated by bio-fermentation inside the decomposition tank inevitably dissipates to the external environment through the tank walls. This heat loss is particularly severe in seasons or regions with lower ambient temperatures, leading to a decrease or drastic fluctuation in the internal temperature. This directly inhibits the activity of microorganisms, reducing the efficiency and effectiveness of waste decomposition.

[0004] To address the issue of heat loss, several solutions have emerged in the prior art involving the installation of insulation layers in the decomposer tank. However, these solutions often employ an integrated, fixed structure with the main body of the decomposer tank, such as permanently attaching the insulation layer to the outer wall of the tank through welding or bonding. While this structure provides some insulation, it introduces new problems: when the main body of the decomposer tank requires inspection, maintenance, or welding repairs, the externally fixed insulation layer must be destructively removed, and then reinstalled after the inspection and repair are completed. This process is complex and costly, significantly increasing the difficulty of equipment maintenance and subsequent operating costs.

[0005] Therefore, this utility model proposes a kitchen waste decomposition tank with an insulated jacket to overcome the shortcomings of the prior art. Summary of the Invention

[0006] To overcome the above shortcomings, this utility model provides a kitchen waste decomposition tank with an insulation jacket, aiming to improve the problem in the prior art where the insulation layer of the kitchen waste decomposition tank is fixed as an integral part of the tank body, resulting in inconvenience and high cost during equipment inspection and maintenance.

[0007] To achieve the above objectives, a kitchen waste decomposition tank with an insulated jacket includes: a decomposition tank body and a discharge pipe connected to the decomposition tank body; as well as an insulation component and a filter component.

[0008] The heat insulation component is sleeved on the outer wall of the decomposition tank body; The thermal insulation component includes a heat insulation layer, a thermal insulation layer, and a protective layer stacked sequentially from the inside out, and the protective layer has interlocking female and male fasteners on opposite edges.

[0009] The filter assembly is disposed inside the discharge pipe.

[0010] Preferably, the filtration assembly includes a filter screen, which is fixed inside the discharge pipe.

[0011] Preferably, the filter assembly further includes a motor and a scraper connected to the motor drive, wherein the working surface of the scraper is in contact with the surface of the filter screen.

[0012] Preferably, the filter assembly further includes a support, a rotating column, and a mounting bracket. The support is fixed inside the body of the decomposition tank, the motor is fixedly connected to the support, the output end of the motor is rotatably connected to the rotating column, the mounting bracket is fixedly connected to the rotating column, and the scraper is connected to the mounting bracket.

[0013] Preferably, the filter assembly further includes a limiting plate and a spring, the scraper is movably connected to the mounting frame through the limiting plate, the spring is disposed on the mounting frame, and the spring pushes the scraper to adhere to the filter screen through the limiting plate.

[0014] Preferably, the mounting bracket has a guide groove, the limiting plate is slidably fitted in the guide groove, and the spring is a compression spring, with its two ends abutting against the inner wall of the bottom of the guide groove and the limiting plate, respectively.

[0015] Preferably, the filter assembly further includes a protective housing, which is disposed outside the motor to protect the motor.

[0016] Preferably, there are multiple scraper blades, which are radially distributed on the mounting frame with the axis of the rotating column as the center.

[0017] Preferably, the support is a beam or frame structure, which spans the upper opening of the decomposition tank body.

[0018] Preferably, the working side of the scraper has a wedge-shaped cross-section to improve the effect of scraping away impurities.

[0019] This utility model has the following beneficial effects: 1. In this utility model, by setting up a heat insulation component consisting of a heat insulation layer, a heat preservation layer and a protective layer, and by fitting the heat insulation component onto the outer wall of the decomposition tank body in the form of a detachable jacket, and then using female and male fasteners for quick fixation, the problem of the heat preservation layer being fixed to the tank body as an integral part in the prior art, which leads to difficulties in disassembly and assembly during equipment maintenance and high costs is solved. This achieves the effect of simplifying the installation and disassembly process, facilitating equipment maintenance and reducing the cost of later use.

[0020] 2. This utility model solves the problem in the prior art that the scraper of the self-cleaning filter is prone to wear after long-term use, resulting in gaps between the scraper and the filter screen, reduced cleaning effect, or even failure, by setting an automatic compensation mechanism consisting of a spring and a limiting plate in the filter assembly. It achieves the effect of automatically compensating for scraper wear, keeping the scraper in close contact with the filter screen, and thus ensuring the long-term, stable, and efficient self-cleaning capability of the equipment.

Detailed Implementation

[0023] 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.

[0024] Reference Figures 1-5 This utility model provides a kitchen waste decomposition tank with an insulation jacket, which aims to solve the problems of unstable decomposition efficiency due to heat loss and poor reliability of self-cleaning function after the discharge port filter device is blocked in the prior art.

[0025] Specifically, it includes a decomposition tank body 1 and a discharge pipe 4. The discharge pipe 4 is connected to the bottom of the decomposition tank body 1. The decomposition tank body 1 is used to contain and decompose kitchen waste, while the discharge pipe 4 is used to guide the decomposed material to be discharged outward.

[0026] It also includes a heat insulation component 2 and a filter component 3. The heat insulation component 2 is fitted onto the outer wall of the decomposition tank body 1, forming a protective enclosure to reduce heat loss from the tank to the outside. The heat insulation component 2 includes a heat insulation layer 201, a heat insulation layer 202, and a protective layer 203, which are stacked sequentially from the inside out. The heat insulation layer 201 first contacts the outer wall of the decomposition tank body 1 to block heat conduction. The heat insulation layer 202 is located between the heat insulation layer 201 and the protective layer 203 to slow down heat loss. The outermost protective layer 203 provides physical protection for the inner heat insulation layer 202 and the heat insulation layer 201. For easy installation and disassembly, the protective layer 203 has interlocking female and male fasteners 204 on its opposite edges. By engaging the female and male fasteners 204, the entire heat insulation component 2 can be securely fastened to the decomposition tank body 1.

[0027] The filter assembly 3 is located inside the discharge pipe 4 to intercept larger residues in the decomposed material.

[0028] The filter assembly 3 includes a filter screen 309, which is fixed inside the discharge pipe 4 and is used to filter and intercept the material flowing through the discharge pipe 4. The filter screen 309 can be a concave cone or a bowl shape to facilitate the collection of impurities.

[0029] To achieve automatic cleaning of the filter screen 309, the filter assembly 3 also includes a motor 303 and a scraper 306 driven by the motor 303. The working surface of the scraper 306 is in contact with the surface of the filter screen 309. When the motor 303 is started, it can drive the scraper 306 to move relative to the filter screen 309, thereby scraping off the food waste residue attached to the surface of the filter screen 309. To improve the scraping effect, the working side of the scraper 306 has a wedge-shaped cross section, which helps to peel the blockage from the mesh of the filter screen 309.

[0030] The filter assembly 3 also includes a support 301, a rotating column 304, and a mounting bracket 305. The support 301 is a beam or frame structure spanning the upper opening of the decomposition tank body 1. The support 301 provides a stable mounting platform for the motor 303, which is fixedly connected to the support 301 via fasteners. The output end of the motor 303 is rotatably connected to the rotating column 304, which extends along the central axis of the decomposition tank body 1. The mounting bracket 305 is fixedly connected to the rotating column 304 and rotates synchronously with it. The scraper 306 is connected to the mounting bracket 305, thus forming a complete transmission chain that enables the motor 303 to drive the scraper 306 to rotate. To ensure smooth and efficient scraping, the axis of the rotating column 304 is perpendicular to the center of the filter screen 309. The number of scraper blades 306 can be multiple. These multiple scraper blades 306 are radially distributed on the mounting bracket 305 with the axis of the rotating column 304 as the center, so as to achieve comprehensive cleaning of the entire surface of the filter screen 309. At the same time, in order to protect the motor 303 from the moisture or corrosive gas inside the decomposition tank body 1, the filter assembly 3 also includes a protective shell 302. The protective shell 302 covers the outside of the motor 303 and forms a sealed protection for the motor 303.

[0031] To address the issue of decreased cleaning effectiveness due to wear and tear on the scraper blade 306 during long-term use, the filter assembly 3 also includes a limiting plate 307 and a spring 308. The scraper blade 306 is not directly fixed to the mounting bracket 305, but is movably connected to it via the limiting plate 307. The spring 308 is mounted on the mounting bracket 305 and continuously pushes the scraper blade 306 against the filter screen 309 via the limiting plate 307. More specifically, the mounting bracket 305 has a guide groove, within which the limiting plate 307 can slide. The scraper blade 306 is fixedly connected to the limiting plate 307. The spring 308 is preferably a compression spring. The two ends of the spring 308 abut against the inner wall of the bottom of the guide groove and the limiting plate 307, respectively. In this structure, the spring 308 always applies a pushing force to the limiting plate 307, so that the working surface of the scraper blade 306 is always pressed against the surface of the filter screen 309 with a certain pressure. When the scraper blade 306 wears, its length will shorten. However, under the continuous push of the spring 308, the limiting plate 307 will automatically move forward a corresponding distance along the guide groove, thereby compensating for the wear of the scraper blade 306 and ensuring that no gap is generated between the scraper blade 306 and the filter screen 309, thus maintaining a long-term, stable and efficient self-cleaning ability.

[0032] Working principle: First, when insulating the main body 1 of the decomposition tank, the insulation component 2, consisting of a heat insulation layer 201, a heat preservation layer 202, and a protective layer 203 stacked sequentially, is wrapped around the outer wall of the main body 1. Then, the female buckles 204 and male buckles 205 on the edge of the protective layer 203 are engaged, tightly fixing the insulation component 2 to the outside of the main body 1. Through the combined action of the heat insulation layer 201 and the heat preservation layer 202, the heat loss from the inside of the main body 1 during the decomposition of kitchen waste is effectively reduced, providing a stable and suitable temperature environment for the decomposition process.

[0033] Secondly, when discharging the decomposition products, the decomposed material enters the discharge pipe 4 from the main body 1 of the decomposition tank. During the flow through the discharge pipe 4, incompletely decomposed kitchen waste residue is intercepted by the filter screen 309 installed inside the discharge pipe 4. When too much kitchen waste residue clogs the surface of the filter screen 309, the motor 303 mounted on the bracket 301 starts, and the motor 303 is protected by the protective shell 302. The start of the motor 303 drives the rotating column 304 to rotate. Since the mounting bracket 305 is fixedly connected to the rotating column 304, the mounting bracket 305 also rotates synchronously. The scraper 306 mounted on the mounting bracket 305 follows the rotation of the mounting bracket 305 and sweeps the surface of the filter screen 309, thereby scraping away the kitchen waste residue clogged on the filter screen 309 and restoring the unobstructed flow of the discharge pipe 4.

[0034] Finally, during long-term operation of the equipment, the working surface of the scraper 306 will wear down due to continuous friction with the filter screen 309. To compensate for this wear, the spring 308 mounted on the mounting bracket 305 continuously applies a pushing force to the limiting plate 307. Since the scraper 306 is fixed to the limiting plate 307, this pushing force is transmitted to the scraper 306, ensuring that the working surface of the scraper 306 remains tightly pressed against the surface of the filter screen 309. When the scraper 306 wears down, the limiting plate 307, driven by the spring 308, will automatically move the scraper 306 forward to compensate for the worn length, thereby ensuring that no gaps are formed between the scraper 306 and the filter screen 309, maintaining the equipment's long-term effective self-cleaning capability.
