Description

Technical Field

[0001] This utility model relates to the field of leak detection device technology, and in particular to a device for detecting milk leakage during the concentrated milk RO membrane production process. Background Technology

[0002] Food safety is related to people's health. It is not only a key concern of relevant national authorities, but also a red line that food manufacturers, especially dairy product manufacturers, cannot cross.

[0003] Currently, dairy manufacturers frequently use leak detectors to check for leaks in dairy production lines to ensure the safety of their products. Commonly used leak detectors are pressure detection devices, such as the one described in patent CN1142866A, entitled "A Method for Detecting Leaks Between Physically Separated and Adjacent First and Second Fluid Paths." This patent utilizes electronic equipment to monitor the positive pressure difference applied between the donor and receiver fluids, which can determine whether leaks exist within the production system. However, this pressure detection method can only detect leaks of relatively large magnitude. When minor leaks occur within the system, they are difficult to detect, leading to a significant increase in the scrap rate of dairy products and impacting normal business operations.

[0004] Therefore, designing a device and method for detecting milk leakage in the concentrated milk RO membrane production process with high accuracy is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This invention provides a device for detecting milk leakage during the production process of concentrated milk RO membrane, solving the technical problem of low accuracy in existing pressure leak detection devices.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a device for detecting milk leakage in the concentrated milk RO membrane production process, comprising: a raw water tank, a first circulation pump, a primary filter, a wastewater tank, a clean water tank, a second circulation pump, a secondary filter, a turbidity meter, and a controller.

[0007] The outlet and inlet of the raw water tank, the first circulating pump, and the primary filter are connected in series via water pipes; the inlet of the wastewater tank is connected to the undersize outlet of the primary filter; the inlet of the clean water tank is connected to the oversize outlet of the primary filter; the inlet of the second circulating pump is connected to the wastewater outlet of the wastewater tank; the inlet of the secondary filter is connected to the outlet of the second circulating pump, and its undersize outlet is directly discharged via a water pipe, while its oversize outlet is connected to the inlet of the clean water tank; the turbidity meter is installed at the water pipe corresponding to the undersize outlet of the secondary filter; the controller is electrically connected to the first circulating pump, the primary filter, the secondary filter, and the turbidity meter.

[0008] The beneficial effects of this invention are: it overturns the traditional method of leak detection in dairy products. First, the raw water in the raw water tank is filtered by a primary filter, and the resulting wastewater is then passed into a wastewater tank. Then, the wastewater in the wastewater tank is filtered by a secondary filter to obtain wastewater within wastewater. Since the turbidity meter is installed at the water pipe corresponding to the liquid outlet of the secondary filter screen, it can detect in real time whether there are leaked milk impurities in the raw water when the wastewater is discharged directly, accurately determine whether there is a leak in the dairy production line, and improve the safety of the dairy production line.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, it also includes a third circulation pump, the inlet of which is connected to the outlet of the clean water tank and its first outlet is connected to the inlet of the sewage tank, and its second outlet is connected to the inlet of the raw water tank.

[0011] The further beneficial effect of adopting the above is that by using the inlet of the third circulation pump and the outlet of the clean water tank to connect the inlet of the third circulation pump to the inlet of the sewage tank and the inlet of the raw water tank respectively, clean water can be used to backwash the sewage tank and the raw water tank, so as to avoid the original impurities affecting the leak test results during the next leak test.

[0012] Furthermore, the primary filters are two connected in parallel.

[0013] Furthermore, the sewage outlet is located at the bottom end of the sewage tank.

[0014] Furthermore, it also includes a cooling water tank, and the water outlet pipe of the clean water tank is connected to the cooling water tank.

[0015] In addition, a method for detecting milk leakage during the concentrated milk RO membrane production process is provided, the specific steps of which are as follows:

[0016] S1. First, use the first circulation pump to extract the raw water from the raw water tank, and then pass it into the first-stage filter for filtration.

[0017] S2. After being filtered by the primary filter, the clean water is fed into the clean water tank, and the wastewater is fed into the wastewater tank.

[0018] S3. First, use the second circulation pump to extract the sewage from the sewage tank, and then pass it into the secondary filter for filtration.

[0019] S4. After filtration by the secondary filter, the obtained clean water is introduced into the clean water tank, and the obtained sewage is discharged from the underflow hole of the secondary filter. At the same time, the turbidity meter installed at the water pipe corresponding to the underflow hole of the secondary filter detects the turbidity of the sewage.

[0020] The beneficial effects of this invention are: it overturns the traditional method of leak detection in dairy products. First, the raw water in the raw water tank is filtered by a primary filter, and the resulting wastewater is then passed into a wastewater tank. Then, the wastewater in the wastewater tank is filtered by a secondary filter to obtain wastewater within wastewater. Since the turbidity meter is installed at the water pipe corresponding to the liquid outlet of the secondary filter screen, it can detect in real time whether there are leaked milk impurities in the raw water when the wastewater is discharged directly, accurately determine whether there is a leak in the dairy production line, and improve the safety of the dairy production line.
