Description

Technical Field

[0001] This utility model relates to the field of liquid food filtration technology, and in particular to a liquid food testing sample filtration device. Background Technology

[0002] Liquid food is a type of liquid food that can flow and provides specific nutrients for human survival, growth, and reproduction. There are many types of liquid food, including dairy products, edible oils, alcoholic beverages, honey, and fruit and vegetable drinks. To ensure food safety, filtering out impurities is an essential step.

[0003] Common liquid food testing sample filtration devices only include filtration functions, capable of filtering impurities in liquid foods, but lack the function of dynamically adjusting the filtration path. This cannot guarantee that all areas of the filter screen can be utilized, and water flow to a fixed position on the filter screen can easily lead to excessive accumulation of impurities in some areas of the filter screen, while other areas of the filter screen do not accumulate impurities, thus causing problems such as local overload and clogging risks.

[0004] Therefore, given that the aforementioned liquid food testing sample filtration device lacks the function of dynamically adjusting the filtration path, resulting in the liquid flow forming a fixed channel on the filter screen surface, causing localized impurity accumulation and overload while other areas suffer from insufficient utilization, there is an urgent need to design a new type of liquid food testing sample filtration device. Utility Model Content

[0005] To overcome the problem that common liquid food testing sample filtration devices lack the function of dynamically adjusting the filtration path, which causes the liquid flow to form a fixed channel on the filter screen surface, resulting in the accumulation of impurities in some areas of the filter screen and insufficient utilization in other areas.

[0006] The technical solution of this utility model is as follows: a liquid food testing sample filtration device, including a filter box; it also includes a top cover, a first guide plate, a drive motor, a drive block, and a baffle plate. The top cover is provided on the top of the filter box and is fixed to the filter box by bolts. The first guide plate is provided on the right side inside the filter box. Two drive motors are provided on the front and rear sides of the bottom of the first guide plate. Two drive blocks are provided on the front and rear sides of the top of the first guide plate corresponding to the positions of the drive motors. The output end of the top of the drive motor passes through the first guide plate and is connected to the bottom of the drive block. A baffle plate is provided around the drive block.

[0007] Preferably, an external PLC controller with pre-set parameters controls the start of two drive motors. The two drive motors control two drive blocks to rotate alternately. The drive blocks drive the baffle plate to move at the top of the first guide plate. The baffle plate blocks the liquid food flowing on the first guide plate, thereby changing the direction of the liquid food flow and realizing the function of dynamically adjusting the filtration path. Common liquid food testing sample filtration devices only include the function of filtration, which can filter impurities in liquid food, but lack the function of dynamically adjusting the filtration path. They cannot ensure that all areas of the filter screen can be utilized, which can easily lead to water flowing to a fixed position on the filter screen. This results in some parts of the filter screen accumulating too much impurity, while other parts of the filter screen do not accumulate impurities, thus causing problems such as local overload and clogging risks.

[0008] Preferably, four rectangular support rods are provided on the right side of the top of the cover, and the top of the four support rods are connected to the liquid storage tank.

[0009] Preferably, a solenoid valve tube is installed at the center of the bottom of the liquid storage tank, with the bottom end of the solenoid valve tube penetrating through the top cover and placed inside the filter box, and an inlet funnel is installed at the center of the top of the liquid storage tank.

[0010] Preferably, a filter screen is installed on the left side of the bottom of the filter box, and a sealed door is movably connected to the front of the filter box via a hinge.

[0011] Preferably, a liquid collection tank is provided at the bottom of the filter box, and the filter box and the liquid collection tank are welded together as one piece.

[0012] Preferably, a second guide plate is provided on the left side inside the liquid collection tank.

[0013] Preferably, a drain pipe is provided on the right side of the middle of the bottom of the liquid collection tank, and support legs are provided at the four corners of the bottom of the liquid collection tank.

[0014] The beneficial effects of this utility model are:

[0015] 1. The two drive motors are started and stopped by an external PLC controller with preset parameters. The two drive motors drive the corresponding drive blocks to perform alternating rotation, which in turn drives the baffle plate to move back and forth along the top plane of the first guide plate. During this process, the baffle plate forms a dynamic barrier to the liquid food flowing down along the first guide plate, forcing the liquid flow direction to deflect periodically. This achieves a continuous change in the flow path of the liquid food on the filter screen surface. By directionally interfering with the liquid flow distribution, the overall utilization rate of the filter screen is effectively improved, and the overload of impurities in fixed areas is avoided.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6This utility model provides an embodiment of a liquid food testing sample filtration device, including a filter box 1; it also includes a top cover 2, a first guide plate 6, a drive motor 7, a drive block 8, and a baffle plate 9. The top cover 2 is provided on the top of the filter box 1 and is fixed to the filter box 1 by bolts. The first guide plate 6 is provided on the right side inside the filter box 1. Two drive motors 7 are provided on the front and rear sides of the bottom of the first guide plate 6. Two drive blocks 8 are provided on the front and rear sides of the top of the first guide plate 6, corresponding to the positions of the drive motors 7. The output end of the top of the drive motor 7 passes through the first guide plate 6 and connects to the bottom of the drive block 8. The drive block 8 is provided with baffle plates 9 around its body. The two drive motors 7 are controlled by an external PLC controller with pre-set parameters. Upon startup, two drive motors 7 control two drive blocks 8 to rotate alternately. The drive blocks 8 drive the baffle 9 to move at the top of the first guide plate 6. The baffle 9 blocks the liquid food flowing on the first guide plate 6, thereby changing the direction of the liquid food flow and realizing the function of dynamically adjusting the filtration path. Common liquid food testing sample filtration devices only include the function of filtration, which can filter impurities in liquid food, but lack the function of dynamically adjusting the filtration path. They cannot ensure that all areas of the filter screen 10 can be utilized, which can easily lead to water flowing to a fixed position on the filter screen. This results in some parts of the filter screen accumulating too much impurity, while other parts of the filter screen do not accumulate impurities, thus causing the problem of local overload and blockage risk.

[0025] Please see Figures 2-6 In this embodiment, four support rods 3 are rectangularly arranged on the right side of the top of the top cover 2. The top of the four support rods 3 is connected to the liquid storage tank 4. The liquid storage tank 4 stores the liquid food that needs to be filtered. A solenoid valve tube 5 is arranged at the center of the bottom of the liquid storage tank 4. The bottom end of the solenoid valve tube 5 passes through the top cover 2 and is placed inside the filter box 1. A liquid inlet funnel 12 is arranged at the center of the top of the liquid storage tank 4. The liquid food is added into the liquid storage tank 4 through the liquid inlet funnel 12. When the liquid food needs to be filtered, the solenoid valve tube 5 is opened, and the liquid food in the liquid storage tank 4 flows into the filter box 1 through the solenoid valve tube 5. A filter screen 10 is arranged on the left side of the bottom of the filter box 1. A sealing door 11 is movably connected to the front of the filter box 1 through a hinge. The liquid food flows to the filter screen 10 through the guidance of the first guide plate 6, and the impurities in the liquid food are filtered by the filter screen 10.

[0026] Please see Figures 1-6In this embodiment, a liquid collection tank 13 is provided at the bottom of the filter box 1. The filter box 1 and the liquid collection tank 13 are welded together. The liquid collection tank 13 is used to store the filtered liquid food. A second guide plate 14 is provided on the left side inside the liquid collection tank 13. The second guide plate 14 guides the filtered liquid food to the drain pipe 15. The drain pipe 15 is provided on the right side of the bottom middle of the liquid collection tank 13. Support legs 16 are provided at the four corners of the bottom of the liquid collection tank 13. When it is necessary to remove the material, the drain pipe 15 can be opened to discharge the filtered liquid food.

[0027] During operation, liquid food is added to the storage tank 4 through the inlet funnel 12. When filtration is required, the solenoid valve 5 is opened, and the liquid food in the storage tank 4 flows into the filter tank 1 through the solenoid valve 5. After entering the filter tank 1, the liquid food falls to the top of the first guide plate 6. The first guide plate 6 guides the unfiltered liquid food towards the filter screen 10. At the same time, the two drive motors 7 are started and stopped by the external PLC controller with preset parameters. The two drive motors 7 drive the corresponding drive blocks 8 to perform alternating rotation, thereby driving the baffle plate 9 along the first guide plate. 6. The top plane moves back to its original position. During this process, the baffle plate 9 forms a dynamic barrier to the liquid food flowing down along the first guide plate 6, forcing the liquid flow direction to deflect periodically. The impurities in the liquid food are filtered through the filter screen 10. After filtration, the liquid food flows into the liquid collection tank 13. The second guide plate 14 guides the filtered liquid food to the drain pipe 15. When it is necessary to remove the material, the drain pipe 15 can be opened to discharge the filtered liquid food. This achieves continuous change in the flow path of the liquid food on the surface of the filter screen 10. By directional interference with the liquid flow distribution, the overall utilization rate of the filter screen is effectively improved, and the overload of impurities in fixed areas is avoided.

[0028] Through the above steps, the external PLC controller with pre-set parameters controls the start of two drive motors 7. The two drive motors 7 control two drive blocks 8 to rotate alternately. The drive blocks 8 drive the baffle 9 to move at the top of the first guide plate 6. The baffle 9 blocks the liquid food flowing on the first guide plate 6, thereby changing the direction of the liquid food flow and realizing the function of dynamically adjusting the filtration path. Common liquid food testing sample filtration devices only include the function of filtration, which can filter impurities in liquid food, but lack the function of dynamically adjusting the filtration path. It cannot ensure that all areas of the filter screen 10 can be utilized. It is easy for water to flow to a fixed position on the filter screen, which leads to excessive accumulation of impurities in some parts of the filter screen, while other parts of the filter screen do not accumulate impurities, thus causing the problem of local overload and blockage risk.
