Description

Technical Field

[0001] This utility model relates to the field of food testing technology, specifically to a solid-liquid separation device for food testing waste. Background Technology

[0002] Food testing experiments generate a significant amount of waste, often a mixture of solids and liquids. The solids are primarily food samples, while the liquids are mainly various organic solvents. The disposal of this waste should adhere to the principle of classification, recycling, and preservation: solids should be treated as solid waste, and liquids as hazardous reagents. Therefore, it is essential to thoroughly separate the solids and liquids in food testing waste. Most existing solid-liquid separation devices rely on direct filtration, which only separates the liquid from the surface layer of solids. This approach is ineffective at separating the liquid absorbed within the solids, resulting in less than ideal separation efficiency. Furthermore, the need to collect the filtered solids increases manual labor. Therefore, we propose a solid-liquid separation device for food testing waste. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a solid-liquid separation device for food testing waste. By squeezing and filtering the food testing waste, solid-liquid separation is achieved, which improves the separation effect during squeezing. It is highly practical and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a solid-liquid separation device for food testing waste, comprising a base plate, a support plate, an extrusion assembly, and a support assembly;

[0005] Base plate: Electric push rods are symmetrically arranged at the four corners of its upper surface. The top of each push rod of the electric push rod is fixedly connected to the lower surface of the support plate. A rectangular hole is provided in the middle of the support plate. A limit ring is placed on the upper surface of the support plate. A filter cloth cylinder is provided on the lower surface of the limit ring. The filter cloth cylinder passes through the rectangular hole and extends to the bottom of the support plate. Support columns are symmetrically arranged on the upper surface of the base plate.

[0006] Extrusion assembly: slidably connected to the lower surface of support plate one, the extrusion assembly is arranged laterally corresponding to the filter cloth cylinder;

[0007] Support components: fixedly connected to the upper surfaces of four support columns respectively; a collection box is placed in the middle of the upper surface of the base plate; the support components correspond to the vertical positions of the collection box and the filter cloth cylinder respectively.

[0008] It also includes a microcontroller, which is set on the upper surface of the base plate. The input end of the microcontroller is electrically connected to an external power supply, and the output end of the microcontroller is electrically connected to the input end of the electric push rod. By squeezing and filtering food testing waste, solid-liquid separation is achieved, and the solids of food testing waste are automatically collected, which improves the separation effect during squeezing, facilitates unloading, and is highly practical.

[0009] Furthermore, the extrusion assembly includes a first pressure plate, a rack, a second pressure plate, teeth, gears, a fixed base, and an electric push rod. The first and second pressure plates are slidably connected to the left and right sides of the lower surface of the first support plate, respectively. The first pressure plate has racks symmetrically arranged on the front and back of its right side, and the second pressure plate has teeth arranged in an array on both its front and back sides. The gears are symmetrically rotatably connected to the front and back ends of the lower surface of the first support plate, and the gears mesh with the adjacent racks and teeth on the same side. The fixed base is located at the right end of the lower surface of the first support plate, and the left side of the fixed base has an electric push rod. The left end of the electric push rod is fixedly connected to the right side of the second pressure plate. The input end of the electric push rod is electrically connected to the output end of the microcontroller to prevent food waste from overflowing to the outside during extrusion.

[0010] Furthermore, the lower surface of the support plate one is symmetrically provided with dovetail grooves at both ends, and the upper surfaces of the pressure plate one and the pressure plate two are symmetrically provided with dovetail sliders. The dovetail sliders are slidably connected to the inner walls of the vertically corresponding dovetail grooves to support and limit the pressure plate one and the pressure plate two.

[0011] Furthermore, the support assembly includes a second support plate, a flow guide groove, and leakage holes. The lower surface of the second support plate is provided with a flow guide groove, and the lower surface of the flow guide groove is fixedly connected to the upper surface of the four support columns respectively. The inner sidewall of the flow guide groove is provided with an array of leakage holes, which correspond to the vertical position of the collection box. The second support plate corresponds to the vertical position of the filter cloth cylinder to prevent the separated liquid from spilling to the outside and causing pollution.

[0012] Furthermore, the upper surface of the second support plate is uniformly provided with through holes, which facilitates the rapid collection of the separated liquid and reduces residue.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This solid-liquid separation device for food testing waste has the following advantages:

[0014] 1. The electric push rod is activated by the microcontroller. The output shaft of the electric push rod pushes the second pressure plate to move to the left under the guidance of the dovetail slider. The second pressure plate drives the gear to move to the left, which in turn drives the gear to rotate. The gear, through meshing with the rack, drives the first pressure plate to move to the right. The first and second pressure plates work together to squeeze the upper end of the filter cloth cylinder, reducing the gap between the left and right side walls of the filter cloth cylinder. This allows for the compression of food testing waste without affecting the feeding process, effectively preventing food testing waste from overflowing to the outside during the solid-liquid separation process.

[0015] 2. The microcontroller controls the retraction of the electric push rod, which in turn moves the support plate downwards. The support plate then moves the pressure plates one and two downwards. The pressure plates, in conjunction with the support plate, compress the food testing waste, causing the liquid in the waste to flow through the micropores of the filter cloth. A portion of the liquid passes through the through-holes and directly enters the collection box for collection, while the remaining liquid flows along the upper surface of the support plate and enters the guide channel. It then flows through the leakage hole into the collection box for further collection, thus achieving the desired food testing effect. To improve the solid-liquid separation of food testing waste, a microcontroller controls an electric push rod to reciprocate. During the extension of the electric push rod, a limiting ring lifts the filter cloth cylinder, changing it from a flat to a vertical position. This causes the food testing waste inside the filter cloth cylinder to gather again. After separation, the limiting ring pulls the filter cloth cylinder upward, allowing the separated solids to be removed and processed. Solid-liquid separation is achieved through squeezing and filtering the food testing waste. The automatic collection of solids from the food testing waste improves the separation effect during squeezing, facilitates unloading, and is highly practical. Attached Figure Description

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.

[0021] Please see Figure 1-3 This embodiment provides a technical solution: a solid-liquid separation device for food testing waste, including a base plate 1, a support plate 3, an extrusion assembly 6, and a support assembly 7;

[0022] Base plate 1: Electric push rods 2 are symmetrically arranged at the four corners of its upper surface. The top of each push rod of electric push rod 2 is fixedly connected to the lower surface of support plate 3. The electric push rod 2 is controlled to retract, and the push rod of electric push rod 2 drives support plate 3 to move downward. The electric push rod 2 is reciprocated and extended by microcontroller 10. During the extension of electric push rod 2, the filter cloth cylinder 5 is lifted by limit ring 4. The filter cloth cylinder 5 changes from a flat state to a vertical state, so that the food testing waste inside the filter cloth cylinder 5 is gathered again, which improves the separation effect during squeezing. A rectangular hole is provided in the middle of support plate 3. Limit ring 4 is placed on the upper surface of support plate 3. Filter cloth cylinder 5 is provided on the lower surface of limit ring 4. Filter cloth cylinder 5 passes through the rectangular hole and extends to the bottom of support plate 3. Support columns 8 are symmetrically arranged on the upper surface of base plate 1.

[0023] The extrusion assembly 6 is slidably connected to the lower surface of the support plate 3. The extrusion assembly 6 is laterally corresponding to the filter cloth cylinder 5. The extrusion assembly 6 includes a pressure plate 61, a rack 62, a pressure plate 63, teeth 64, a gear 65, a fixed base 66, and an electric push rod 67. The pressure plate 61 and pressure plate 63 are slidably connected to the left and right sides of the lower surface of the support plate 3, respectively. The right side of the pressure plate 61 is symmetrically provided with racks 62, and the front and rear sides of the pressure plate 63 are arrayed with teeth 64. The gear 65 is symmetrically rotatably connected to the front and rear ends of the lower surface of the support plate 3, and meshes with the adjacent racks 62 and teeth 64 on the same side. The fixed base 66 is located at the right end of the lower surface of the support plate 3. The left side of the fixed base 66 is provided with an electric push rod 67, and the left end of the push rod 67 is connected to the right side of the pressure plate 63. With a fixed connection, the electric push rod 67 is activated. The output shaft of the electric push rod 67 pushes the pressure plate 63 to move to the left under the guidance of the dovetail slider 11. The pressure plate 63 drives the tooth 64 to move to the left, and the tooth 64 drives the gear 65 to rotate. The gear 65, through meshing with the rack 62, drives the pressure plate 61 to move to the right. The pressure plate 61 and the pressure plate 63 work together to squeeze the upper end of the filter cloth cylinder 5, reducing the gap between the left and right side walls of the filter cloth cylinder 5, and preventing food testing waste from overflowing to the outside during squeezing. The lower surface of the support plate 3 is symmetrically provided with dovetail grooves 301 at both ends. The upper surfaces of the pressure plate 61 and the pressure plate 63 are symmetrically provided with dovetail sliders 11. The dovetail sliders 11 are slidably connected to the inner walls of the vertically corresponding dovetail grooves 301 to support and limit the pressure plate 61 and the pressure plate 63.

[0024] Support component 7: Fixedly connected to the upper surfaces of the four support columns 8 respectively. A collection box 9 is placed in the middle of the upper surface of the base plate 1. The support component 7 corresponds vertically to the collection box 9 and the filter cloth cylinder 5 respectively. The support component 7 includes a second support plate 71, a guide channel 72, and leakage holes 73. The lower surface of the second support plate 71 is provided with a guide channel 72, and the lower surface of the guide channel 72 is fixedly connected to the upper surfaces of the four support columns 8 respectively. The inner sidewall of the guide channel 72 is provided with a series of leakage holes 73, which correspond vertically to the collection box 9. The second support plate 71 corresponds vertically to the filter cloth cylinder 5 to prevent the separated liquid from spilling to the outside. To prevent contamination, pressure plates 61 and 63, in conjunction with support plate 71, compress the food testing waste, causing the liquid in the waste to flow out through the micropores of the filter cloth cylinder 5. Part of the liquid flows directly into the collection box 9 through the through hole 12 for collection, while the other part flows along the upper surface of support plate 71 and enters the guide groove 72, then through the leakage hole 73 into the collection box 9 for collection, thereby achieving solid-liquid separation of the food testing waste. The upper surface of support plate 71 is uniformly provided with through holes 12 to facilitate rapid collection of the separated liquid and reduce residue.

[0025] It also includes a microcontroller 10, which is disposed on the upper surface of the base plate 1. The input terminal of the microcontroller 10 is electrically connected to an external power supply, and the output terminal of the microcontroller 10 is electrically connected to the input terminal of the electric push rod 2. The input terminal of the electric push rod 67 is electrically connected to the output terminal of the microcontroller 10.

[0026] The working principle of the solid-liquid separation device for food testing waste provided by this utility model is as follows:

[0027] Food testing waste is fed into the filter cloth cylinder 5 from above. Then, the microcontroller 10 activates the electric push rod 67. The output shaft of the electric push rod 67 pushes the pressure plate 63 to the left under the guidance of the dovetail slider 11. The pressure plate 63 drives the gear 64 to move to the left, which in turn drives the gear 65 to rotate. The gear 65, through meshing with the rack 62, drives the pressure plate 61 to move to the right. The pressure plates 61 and 63 work together to squeeze the upper end of the filter cloth cylinder 5, reducing the gap between the left and right side walls. Then, the microcontroller 10 controls the electric push rod 2 to retract. The push rod of the electric push rod 2 drives the support plate 3 to move downwards. The support plate 3 then drives the pressure plates 61 and 63 to move downwards respectively. The pressure plates 61 and 63, through their interaction with the support plate 71, press the food testing waste... The liquid in the food testing waste is squeezed out through the micropores of the filter cloth cylinder 5. Part of the liquid flows directly into the collection box 9 through the through hole 12 and is collected. The other part of the liquid flows along the upper surface of the support plate 71 and enters the guide groove 72. Then it enters the collection box 9 through the leakage hole 73 and is collected, thus realizing the solid-liquid separation of the food testing waste. In order to improve the separation effect, the electric push rod 2 can be controlled by the microcontroller 10 to reciprocate. During the extension of the electric push rod 2, the filter cloth cylinder 5 is lifted by the limiting ring 4. The filter cloth cylinder 5 changes from a flat state to a vertical state, so that the food testing waste inside the filter cloth cylinder 5 is gathered again, which improves the separation effect during squeezing. After the separation is completed, the filter cloth cylinder 5 is lifted upward by the limiting ring 4, and the separated solid is taken out for processing. The operation is simple and convenient.

[0028] It is worth noting that the electric linear actuator 2 and electric linear actuator 67 disclosed in the above embodiments can be freely configured according to the actual application scenario. It is recommended that the electric linear actuator 2 be a WDTP type micro electric linear actuator, and the electric linear actuator 67 can be a JRZ02 type DC electric linear actuator. The microcontroller 10 controls the operation of the electric linear actuator 2 and electric linear actuator 67 using methods commonly used in the prior art.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
