Description

Technical Field

[0001] This utility model relates to the technical field of kitchen waste sand removal equipment, and in particular to a kitchen waste slurry fine sand removal component. Background Technology

[0002] A vibrator, generally speaking, refers to a device that works using the principle of mechanical vibration and is widely used in fields such as construction and industrial manufacturing. Its working principle is mainly based on the high-speed rotation of an internal vibration source (such as an eccentric block or eccentric shaft) driven by an electric motor or other power source, thereby generating high-frequency micro-amplitude vibrations. These vibrations can be effectively transmitted to the materials or objects that need to be processed, achieving compaction, loosening, or other specific effects. The vibrator assembly includes a vibration output motor and connecting and transmitting components.

[0003] Food waste refers to the waste generated in daily life, food processing, catering services, and institutional catering. The fine sand, small hard shells, small iron pieces, fragments of ceramics, and glass (hereinafter referred to as "sand particles") contained within it have always been the most challenging problem in the entire food waste treatment process. Sand particles inevitably lead to slag deposition in the treatment equipment and liquid phase conveying system, causing equipment shutdowns and pipe blockages. Furthermore, prolonged system operation can cause severe wear and tear on pipes, pumps, and agitators. Therefore, it is essential to install a sand removal system in the food waste treatment process.

[0004] Patent No. CN2021625950.4 describes a kitchen waste slurry treatment equipment and method. This equipment includes a mixing device with a feed end and a liquid inlet, the feed end being higher than the liquid inlet. An aeration and sand removal device is connected to the discharge end of the mixing device. This device includes an aeration tank, a gas diffusion mechanism, and a sand removal mechanism. At least part of the gas diffusion mechanism is located within the aeration tank, where diffused gas agitates the liquid to form a spiral flow. The sand removal mechanism is located at the bottom of the aeration tank. A sludge-liquid separation device is connected to the discharge end of the aeration and sand removal device. This device includes a filtrate tank and a filtration mechanism located above the filtrate tank. This invention achieves multi-stage treatment of kitchen waste using a series of devices, solving the problems of low sand and sludge removal efficiency and high equipment failure rate in existing technologies. However, this device has the following problems: firstly, the sand removal screen is difficult to clean and prone to clogging; secondly, the structure is complex, costly, and occupies a large area.

[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] Example 1

[0025] like Figs. 1 to 4As shown, this utility model provides a component for refining and removing sand from kitchen waste slurry, including a refining chamber 1. A vibration protection cylinder 2 is connected to the left side of the refining chamber 1. A rubber damping pad is provided on the inner side of the vibration protection cylinder 2, and a rotating motor 3 is provided inside the vibration protection cylinder 2. An output shaft is provided at the center of the right side of the rotating motor 3. A spiral blade shaft 31 is fixedly connected to the right side of the output shaft. The spiral blade shaft 31 is located in the middle of the inner side of the refining chamber 1. A sand screen 11 is provided at the right end of the refining chamber 1. A limiting ring 4 is connected to the lower outer side of the refining chamber 1 and the vibration protection cylinder 2. A vibration table 41 is connected to the lower end of the limiting ring 4. A vibrator assembly 42 is provided at the lower end of the vibration table 41.

[0026] Furthermore, the upper left side of the vibration protection cylinder 2 is provided with a heat dissipation hole 22, and the lower end of the heat dissipation hole 22 corresponds to the rotating motor 3. The heat dissipation hole 22 is directly facing the rotating motor 3 at the lower end, which effectively dissipates heat from the rotating motor 3, prevents the rotating motor 3 from overheating, and has a high safety factor.

[0027] Furthermore, a discharge port 12 is provided at the lower right end of the refining chamber 1, and a feed port 15 is provided at the upper left end of the refining chamber 1. The discharge port 12 is located on the right side of the limiting ring 4, and the length of the discharge port 12 is less than the distance from the refining chamber 1 to the lower end face of the limiting ring 4. The discharge port 12 is used to clean sand and gravel impurities inside and remove residual garbage when the entire sand removal component is not working. Clean water is introduced into the feed port 15, the discharge port 12 is opened, and then the vibrator assembly 42 is used to vibrate, so that excess sand and gravel impurities come out from the discharge port 12. It is simple and convenient. The discharge port 12 is located at the lower end and does not affect the normal operation of the overall structure.

[0028] Furthermore, a structural rib 13 is provided at the center of the sand screening mesh 11. The structural rib 13 includes a connecting disc 131. Six identical connecting ribs 132 are evenly connected to the outer side of the connecting disc 131. Three identical connecting holes 133 are provided at adjacent positions on the outer side of the connecting ribs 132. A connecting bolt is provided in the connecting hole 133. The connecting bolt is threaded to a retaining ring 134. The outer side of the retaining ring 134 is connected to the refining chamber 1. The structural rib 13 is used to ensure the structural strength of the entire sand screening mesh 11 and reduce the damage of sand and gravel impurities to the sand screening mesh 11. The connecting holes 133 are used for connection and installation. When disassembly is required, it is also more convenient to loosen the connecting bolts. The structure is simple, easy to use, and low in cost.

[0029] Furthermore, the refining chamber 1 is provided with an inner layer, the inner layer is provided with heat insulation cotton, and the inner layer is provided with a material bucket 14. The material bucket 14 is provided with a spiral blade shaft 31. When the rotating motor 3 is working, it will generate heat, which will be transferred to the position of the refining chamber 1. The heat insulation cotton can ensure the internal temperature of the refining chamber 1 and prevent the slurry from coagulating and sticking to the wall inside the refining chamber 1.

[0030] Furthermore, a movable block is connected to the center of the upper end of the limiting ring 4. The movable block is slidably connected to a sliding groove. The sliding grooves are located on the outer sides of the refining chamber 1 and the vibration protection cylinder 2, and both sliding grooves are semi-circular in shape. The lower end of the limiting ring 4 is connected to the vibrator assembly 42. The vibrator assembly 42 includes a vibrator and a connecting block for transmitting vibration. The connecting block and the limiting block 4 are connected. In this way, when the vibrator works, it will transmit the vibration to the limiting ring 4. The limiting ring 4 is movably connected to the vibration protection cylinder 2 and the refining chamber 1, and the vibration will also be transmitted to the refining chamber 1, thereby causing the sand and gravel impurities stuck on the sand screen 11 to fall off, improving the sand screening efficiency. The principle of the vibrator is that the internal vibration source (such as an eccentric block or eccentric shaft) rotates at high speed under the drive of an electric motor or other power source, thereby generating high-frequency micro-amplitude vibration.

[0031] Working process: First, the slurry to be processed is fed into the material tank 14 in the refining chamber 1 through the feed inlet 15. Then, the motor 3 and the vibrator assembly 42 are turned on. The motor 3 drives the spiral blade shaft 31 to rotate, which refines the slurry. The refined slurry is pushed out from the screen 11. The vibrator assembly 42 vibrates the entire component, and the sand and gravel impurities stuck on the screen 11 can also be shaken off, ensuring higher screening efficiency. The entire component has a simple structure, simple principle, low cost, small footprint, high screening efficiency, and is easy to clean the screen 11.
