Description

Technical Field

[0001] This utility model relates to the field of CIP cleaning system technology, and in particular to a waste liquid recovery device for CIP cleaning systems. Background Technology

[0002] Cleaning in process (CIP) systems are core equipment for achieving efficient cleaning and aseptic production in the food, pharmaceutical, and chemical industries. Their advantages, such as automated operation and thorough cleaning, have made them a key support for ensuring product quality and production compliance. However, with the upgrading of global industrial cleanliness standards and increasingly stringent environmental regulations, the issue of wastewater recovery and treatment generated by CIP systems is becoming increasingly prominent. This wastewater may contain varying concentrations of acid and alkali cleaning agents, food residues, or pharmaceutical intermediates, and may also contain solid impurities detached from pipelines. Improper handling can not only waste water resources and chemical reagents but also pose environmental pollution risks.

[0003] Current mainstream CIP wastewater recovery methods have several technical limitations: First, existing devices mostly use a single pipeline to collect wastewater from all cleaning tanks, failing to differentiate between the high-turbidity wastewater from the initial washing stage and the low-pollution wastewater from the final washing stage. This results in higher costs for unified purification during subsequent treatment, significantly reducing water reuse rates. Second, the filter components of these recovery devices use a fixed structure, requiring shutdown and disassembly for cleaning after filter clogging. Furthermore, the lack of a targeted slag discharge design allows solid impurities to accumulate in the tank, causing pipeline blockages. Third, in scenarios with multiple cleaning tanks operating simultaneously, existing devices rely heavily on manual valve control of wastewater flow, making dynamic adaptation and adjustment difficult. This often leads to pipeline pressure fluctuations or wastewater retention, affecting recovery efficiency and increasing energy costs.

[0004] To address the above problems, this utility model proposes a waste liquid recovery device for CIP cleaning systems. Utility Model Content

[0005] Based on the technical problems of waste liquid recovery in existing CIP cleaning systems, this utility model proposes a waste liquid recovery device for CIP cleaning systems.

[0006] This utility model proposes a waste liquid recovery device for a CIP cleaning system, including a cleaning tank. Each cleaning tank has a water outlet pipe fixedly connected to its outlet end. One end of the water outlet pipe is fixedly connected to an adjustment mechanism. A storage tank is provided on one side of the adjustment mechanism.

[0009] Preferably, one end of the T-shaped rod is located inside the transfer tank, the T-shaped rod is configured as an arc surface, and the side of the lever is pressed and connected to one end of the T-shaped rod.

[0010] Preferably, the filter disc includes an annular outer frame and a stainless steel filter screen, wherein the stainless steel filter screen is detachably fixed to the inner cavity of the annular outer frame by bolts.

[0011] Preferably, a turbidity sensor is fixedly installed at the center of the inner bottom wall of the cleaning tank, and a slag discharge port is opened on the outer side wall of the transfer tank, with a sealing door rotatably connected to the inner wall of the slag discharge port.

[0012] The beneficial effects of this utility model are as follows: To achieve precise waste liquid classification and recycling, a turbidity sensor inside the cleaning tank can detect the turbidity of the waste liquid in real time. Combined with a solenoid valve and a piston-type T-shaped rod with a spring on the outlet pipe, it can control the delivery of waste liquid from different cleaning tanks according to the pollution level, preventing the mixing of waste liquids with different pollution levels and improving subsequent recycling efficiency and resource reuse rate.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-3 A waste liquid recovery device for a CIP cleaning system includes a cleaning tank 1. Each cleaning tank 1 has a water outlet pipe 2 fixedly connected to its outlet end. One end of the water outlet pipe 2 is fixedly connected to an adjustment mechanism 3. A storage tank 4 is provided on one side of the adjustment mechanism 3. One end of the adjustment mechanism 3 and the storage tank 4 are fixedly connected through the water outlet pipe 2. Each water outlet pipe 2 is equipped with a solenoid valve 5.

[0017] In this embodiment, the adjustment mechanism 3 includes a transfer tank 31. A motor 32 is provided on the upper end of the sealing cover of the transfer tank 31. The inner bottom wall of the transfer tank 31 is arc-shaped. A filter disc 35 is provided on the inner side wall of the transfer tank 31. A rotating column 33 is rotatably connected to the center of the filter disc 35 through a sealed bearing. A paddle 34 is provided on the outer surface of the rotating column 33. The side of the transfer tank 31 is arrayed with mounting holes 36 that are adapted to the water outlet pipe 2. A connecting pipe 37 is fixedly connected to the inner wall of the mounting hole 36.

[0018] Specifically, the output shaft of the motor 32 passes through the sealing cover of the transfer tank 31 and is fixedly connected to the top of the rotating column 33. After the motor 32 is started, it can drive the rotating column 33 and the lever 34 to rotate synchronously. The filter disc 35 is horizontally installed in the middle of the inner side of the transfer tank 31. Its annular outer frame is tightly fitted with the inner wall of the transfer tank 31 to form a waste liquid filtration channel. The mounting holes 36 are evenly distributed along the circumference of the side wall of the transfer tank 31 to adapt to the water outlet pipe 2 connected to the cleaning tank 1, thereby improving the expandability of the device.

[0019] In this embodiment, the inner wall of one end of the connecting pipe 37 is fixedly connected to the inner wall of one end of the water outlet pipe 2. A limiting ring 38 is slidably connected to the inner wall of the connecting pipe 37. A spring 39 is fixedly connected to one side of the limiting ring 38. One end of the spring 39 is fixedly connected to the inner wall of the connecting pipe 37. A T-shaped rod 310 is provided inside the connecting pipe 37. A connecting block 311 is arrayed on the outer surface of one end of the T-shaped rod 310. One end of the connecting block 311 is fixedly connected to the inner wall of the limiting ring 38.

[0020] Specifically, the connecting pipe 37 and the outlet pipe 2 are fixed by welding, and a sealing gasket is set at the connection to prevent waste liquid leakage; the outer diameter of the limiting ring 38 matches the sliding groove opened on the inner wall of the connecting pipe 37 to ensure smooth sliding; when the spring 39 is in its natural state, one end of the connecting pipe 37 is set as a ball shape, one end of the T-shaped rod 310 is located in the spherical space, one end of the T-shaped rod 310 seals the connection between the spherical space and the tubular space of the connecting pipe 37, and the sealing end of the T-shaped rod 310 is in contact with the inner wall of the connecting pipe 37 to achieve the normally closed state of the pipeline.

[0021] In this embodiment, one end of the T-shaped rod 310 is located inside the transfer tank 31. The T-shaped rod 310 is configured as an arc surface, and the side of the paddle 34 is pressed and connected to one end of the T-shaped rod 310.

[0022] Specifically, the arc end of the T-shaped rod 310 faces the rotating column 33. When the lever 34 rotates to contact the arc surface, it pushes the T-shaped rod 310 into the connecting pipe 37 through radial extrusion force, and simultaneously drives the limiting ring 38 to compress the spring 39, so that the connecting pipe 37 is connected to the transfer tank 31. After the lever 34 disengages, the spring 39 resets and pushes the limiting ring 38 and the T-shaped rod 310 back to their original positions, closing the pipeline and realizing intermittent control of waste liquid transportation.

[0023] In this embodiment, the filter disc 35 includes an annular outer frame and a stainless steel filter screen, which is detachably fixed to the inner cavity of the annular outer frame by bolts.

[0024] Specifically, the stainless steel filter screen is made of 304 stainless steel with a mesh size of 50-100μm, which can effectively intercept solid impurities in waste liquid with a particle size larger than the mesh size; the outer ring frame has 4-6 bolt holes on its edge, which can be aligned with the corresponding holes of the stainless steel filter screen and then tightened to achieve detachable fixing, making it convenient to replace the filter screen individually later.

[0025] In this embodiment, a turbidity sensor is fixedly installed at the center of the inner bottom wall of the cleaning tank 1, and a slag discharge port 312 is opened on the outer side wall of the transfer tank 31. A sealing door is rotatably connected to the inner wall of the slag discharge port 312.

[0026] Specifically, the turbidity sensor and the solenoid valve 5 are both electrically connected to an external controller. The sensor collects waste liquid turbidity data in real time and transmits it to the controller. The controller controls the opening and closing of the solenoid valve 5 of the corresponding outlet pipe 2 according to the preset threshold. The slag discharge port 312 is located on the lower part of the outer wall of the transfer tank 31, flush with the lowest point of the inner bottom wall arc surface. The sealing door is connected to the slag discharge port 312 through a hinge. A rubber sealing gasket is provided on the contact surface between the door and the slag discharge port 312 to ensure the sealing when closed.

[0027] Operating principle: A turbidity sensor inside the cleaning tank 1 detects the degree of contamination of the liquid inside. Based on the detection results, the controller controls the solenoid valve 5 of the corresponding outlet pipe 2 to open. At the same time, the servo motor 32 starts, driving the rotating column 33 and the paddle 34 to rotate. The paddle 34 squeezes the T-shaped rods 310 corresponding to each connecting pipe 37 in order of contamination level, so that the waste liquid from different cleaning tanks 1 enters the transfer tank 31 in order of contamination level. After the waste liquid is filtered by the stainless steel filter screen of the filter plate 35, solid impurities are intercepted. The filtered waste liquid is transported to the storage tank 4 through the outlet pipe 2. The sealing door of the slag discharge port 312 is opened periodically to guide the waste slag from the filter plate 35 to be discharged in a concentrated manner, completing the slag discharge and waste liquid recycling process.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
