Description

Technical Field

[0001] This utility model relates to the technical field of kitchen waste treatment, and in particular to a splash-proof device for conveying fine residue in kitchen waste treatment. Background Technology

[0002] During the food waste treatment process, the food waste needs to be conveyed by a fine residue discharge screw and discharged into the fine residue collection tank below.

[0003] A search revealed that Chinese Patent Publication No. CN114733233A discloses a method for efficient separation of fine slag. The method includes the following steps: blast furnace flushing water flows into a primary sedimentation tank via a ditch for primary sedimentation; a conical hopper is installed at the bottom of the primary sedimentation tank; a pump lifts the fine slag deposited in the conical hopper to an aeration box; the fine slag, after being buffered by the aeration box, enters a stirring cage; the water separated by the stirring cage flows back into the primary sedimentation tank through the overflow port of the stirring cage; and the slag separated by the stirring cage falls onto a conveyor belt. This method achieves good separation, low fine slag content in the flushing water, significantly reduced equipment failure rate, and improved system safety and stability.

[0004] Specifically, such as Figure 1 As shown, because the fine slag discharge port of the fine slag discharge screw is relatively high, the material is more likely to splash when it falls (into the fine slag collection tank below), which has a significant impact on the overall cleanliness of the ground and the working environment; workers need to clean up the splashed material on the ground every day, which is a tedious and repetitive task.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a splash-proof device for conveying fine residue in food waste treatment, making it more valuable for industrial use. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a splash-proof device for conveying fine residue in kitchen waste treatment.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A splash-proof device for conveying fine slag in food waste treatment, comprising, from top to bottom, a fine slag discharge screw and a fine slag collection tank adapted to the fine slag discharge screw;

[0009] The fine slag discharge screw is distributed along the left and right direction. An inclined pipe that slopes downward is installed on the right side of the fine slag discharge screw. The inclined pipe is located above the fine slag collection tank near the middle.

[0010] A downward-sloping buffer baffle is installed at the top of the discharge port located below the inclined pipe;

[0011] An upward-extending cover is provided on the top of the fine residue collection tank.

[0012] As a further improvement of this utility model, the inclination angle between the inclined pipe and the fine slag discharge screw is 30~60 degrees.

[0013] As a further improvement of this utility model, the top of the buffer baffle is movably mounted on the inclined pipe.

[0014] As a further improvement of this utility model, several buffer lines are provided on the inner wall of the inclined pipe.

[0015] As a further improvement of this utility model, the buffer texture is a straight strip structure.

[0016] As a further improvement of this utility model, the buffer texture is a corrugated structure.

[0017] As a further improvement of this utility model, a protrusion array is provided on the inner side of the buffer baffle.

[0018] As a further improvement of this utility model, the protrusion array is composed of several arc-shaped protrusions.

[0019] As a further improvement of this utility model, the outer cover is a trumpet-shaped structure that is wide at the top and narrow at the bottom.

[0020] By means of the above solution, this utility model has at least the following advantages:

[0021] This invention uses an inclined pipe to reduce the falling height of the material, installs a buffer baffle at the slag outlet to reduce the falling speed of the material, and the outer cover can greatly reduce the splashing of the material.

[0022] After being put into use, this utility model greatly reduces the frequency and intensity of workers' cleaning work, and the material discharge is smooth and less prone to blockage.

[0023] This invention reduces the kinetic energy of falling materials and greatly minimizes the range of fine slag splashing by using a triple effect of lowering the height and optimizing the angle of the inclined pipe, as well as controlling the speed of the buffer baffle, thereby essentially eliminating pollution to the surrounding environment.

[0024] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the following are the preferred embodiments of this utility model and are described in detail with reference to the accompanying drawings.

[0032] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0034] The first embodiment of this utility model:

[0035] The purpose of this embodiment is to provide a splash-proof device for conveying fine residue of kitchen waste, which can effectively solve the problem of splashing caused by height difference during material discharge, improve the working environment, and reduce material waste.

[0036] like Figure 2 As shown in the figure, a splash-proof device for conveying fine slag in kitchen waste treatment according to this embodiment mainly includes a fine slag discharge screw 1, a fine slag collection tank 2, an inclined pipe 3, a buffer baffle 4, and an outer cover 5.

[0037] The fine slag discharge screw 1 is distributed along the left and right direction and is located above the fine slag collection tank 2. The fine slag discharge screw 1 transports and discharges the kitchen waste into the fine slag collection tank 2 below. The fine slag discharge screw 1 is a screw conveyor mechanism commonly used in the art.

[0038] The initial height of the slag discharge screw 1, controlled by a frequency converter, is 4m. A section of inclined stainless steel pipe 3 is welded at the slag discharge port with a welding angle of 30-60 degrees. This structural design reduces the height of the slag discharge port, alters the trajectory and speed of the falling material, and initially reduces the possibility of material splashing.

[0039] The spiral running frequency is controlled at 35Hz by a frequency converter, which can be flexibly adjusted according to the characteristics of the material, the required output, and other actual conditions to further reduce the output and speed, thereby reducing material splashing at the source.

[0040] A buffer baffle 4 is welded at the outlet of the inclined pipe 3, with a welding angle of 30-60 degrees. After the material hits the baffle, its movement direction is further changed, greatly reducing the falling speed of the material and effectively preventing material splashing.

[0041] The top of the aforementioned buffer baffle 4 is movably mounted on the inclined pipe 3. This mounting structure allows the buffer baffle 4 to be rotated and adjusted.

[0042] A brief description of an example of the mounting structure for the buffer baffle 4:

[0043] The buffer baffle 4 is connected to the cylinder via a connecting mechanism, allowing for angle adjustment under the cylinder's influence. Specifically, the connecting mechanism includes a rotating shaft fixedly connected to the buffer baffle 4. The rotating shaft is installed in a bearing seat fixed at the pipe outlet and can rotate freely. The piston rod of the cylinder is hinged to the end of the rotating shaft via a connecting rod. When the piston rod extends or retracts, it drives the rotating shaft to rotate, thereby adjusting the angle of the buffer baffle 4.

[0044] To fix the buffer baffle 4 in its adjusted state, a positioning pin and positioning hole structure is provided. Multiple positioning holes are evenly spaced along the rotation angle range of the buffer baffle 4 on the fixed bracket at the pipe outlet. Positioning pin mounting holes are provided on the rotation shaft of the buffer baffle 4, and the positioning pins are installed in the positioning pin mounting holes via a spring pressing mechanism. When the buffer baffle 4 is adjusted to the desired angle, the positioning pins are inserted into the corresponding positioning holes under the action of the spring, locking the position of the buffer baffle 4. When further adjustment is needed, the positioning pins are manually pressed to overcome the spring pressure and pull them out of the positioning holes, allowing for angle adjustment.

[0045] A 10-ton fine slag collection tank 2 is installed below the fine slag discharge screw 1 to temporarily store the material and reduce the impact force of the material falling directly. The fine slag collection tank 2 can be made of a suitable material, such as high-strength carbon steel or stainless steel, to ensure its durability and corrosion resistance, depending on the actual production needs.

[0046] An upward-extending outer cover 5 is provided on the top of the fine slag collection tank 2. The outer cover 5 has a flared structure that is wider at the top and narrower at the bottom. The outer cover is made of a material that is compatible with the collection tank and is fixed to the top of the collection tank by means of welding or bolting.

[0047] The trumpet-shaped outer cover 5 on the top of the fine slag collection tank 2 can effectively block and guide the material that may splash out of the fine slag collection tank 2 back down. Together with the modified inclined pipe 3 and buffer baffle 4, it forms a multi-layer protection, solves the problem of material splashing in all aspects, significantly improves the hygiene of the working environment, and reduces material residue on the workshop floor, equipment, etc.

[0048] The trumpet-shaped outer cover 5, with its wide top and narrow bottom structure, expands the interception range of splashed materials without taking up too much horizontal space. It is especially suitable for industrial production scenarios with limited space. At the same time, its upward extension shape naturally connects with structures such as collection tanks and slag outlets, resulting in a compact and reasonable overall layout.

[0049] The outer cover 5 has a simple structure with no complex moving parts, making it easy to install and disassemble, facilitating cleaning and maintenance of the fine slag collection tank. Furthermore, the smooth inner wall of the outer cover 5 prevents material from adhering, reducing cleaning difficulty and maintenance workload.

[0050] like Figure 3 and Figure 4 Several buffer lines 6 are provided on the inner wall of the inclined pipe 3. The buffer lines 6 can be straight strips or corrugated. The buffer lines 6 are integrally formed with the inner wall of the pipe by casting or machining.

[0051] The buffer texture 6 on the inner wall of the inclined pipe 3 effectively slows down the material flow rate by increasing friction and changing the material movement trajectory, reducing the initial velocity of the material at the pipe outlet and reducing the splashing phenomenon caused by the material rushing out of the pipe at high speed.

[0052] The straight strip-shaped buffer texture is easy to process and manufacture, and can provide stable friction.

[0053] The corrugated structure of the buffer pattern can further disrupt the movement of materials, making the material movement more stable and the anti-splashing effect better.

[0054] An array of protrusions is provided on the inner side of the buffer baffle 4. The array of protrusions consists of several arc-shaped protrusions with a height of 3-5mm and a spacing of 20-30mm.

[0055] The array of protrusions on the inner side of the buffer baffle 4 uses the arc-shaped protrusions to disperse the impact force of the material and change the direction of material movement, so that the material leaves the baffle in a smoother manner. Together with the pipe buffer texture 6 and the trumpet-shaped outer cover 5, a multi-layer anti-splash system is formed, which solves the problem of material splashing in an all-round way, significantly improves the hygiene of the working environment, and reduces material residue on the workshop floor, equipment, etc.

[0056] A brief description of the working principle of this embodiment:

[0057] When the material enters the inclined pipe 3 at the slag outlet from the fine slag discharge screw 1, the buffer texture 6 on the inner wall of the pipe comes into contact with the material. By increasing the friction between the material and the inner wall of the pipe, the flow rate of the material is slowed down, and the trajectory of the material is changed, making the movement of the material in the pipe more stable.

[0058] Next, based on the material characteristics and discharge requirements, the buffer baffle 4 is adjusted to a suitable angle using a cylinder, and then fixed using a positioning pin and positioning hole structure. (This process is optional)

[0059] When the material hits the buffer baffle 4, the array of protrusions on the inner side of the buffer baffle 4 comes into contact with the material. The arc-shaped protrusions disperse the impact force of the material, further reducing the falling speed of the material and changing the direction of the material's movement.

[0060] At this time, even if a small amount of material still splashes, due to the presence of the trumpet-shaped outer cover 5 at the top of the fine slag collection tank 2, the splashed material will be blocked by the inner wall of the outer cover 5 and guided back into the fine slag collection tank 2.

[0061] During this process, the frequency converter controls the spiral running frequency to precisely adjust the material discharge rate and speed, so that the material can fall relatively smoothly into the slag collection tank 2 below, thereby completely solving the problem of fine material splashing.

[0062] The second embodiment of this utility model:

[0063] A brief description of the installation steps for a splash-proof device for conveying fine residue in food waste treatment:

[0064] First, based on the layout and space of the production site, determine the installation location of the slag collection tank 2 to ensure its stability and ease of material collection and subsequent cleaning. Secure the outer cover 5 to the top of the fine slag collection tank 2 using welding or bolting, ensuring a firm connection and good sealing to prevent material leakage.

[0065] Connect the fine slag discharge screw 1 to the existing material conveying system and adjust its height and angle to ensure that it can smoothly convey the material to the slag outlet.

[0066] At the slag outlet, a stainless steel inclined pipe 3 with a diameter of 300mm, a length of 1m, a welding angle of 30 degrees, and buffer texture 6 on the inner wall is accurately welded according to design requirements. During the welding process, the welding quality must be ensured to prevent problems such as material leakage.

[0067] Install the bearing housing and rotating shaft, and fix the stainless steel buffer baffle 4 with the raised array to the rotating shaft. Install the cylinder, and hinge the cylinder piston rod to the end of the rotating shaft via a connecting rod. Make positioning holes at corresponding positions on the fixed bracket, and install the spring pressing mechanism and positioning pin on the rotating shaft.

[0068] Install a frequency converter and connect it to the motor of the fine slag discharge screw 1. Debug the frequency converter so that it can stably control the screw's operating frequency at 35 Hz, and can be flexibly adjusted according to actual needs.
