Abstract
Description
Technical Field
[0001] This utility model relates to a device for detecting the water content of steamed balls and blanched skin, belonging to the technical field of donkey-hide gelatin production and manufacturing facilities. Background Technology
[0002] Blanching is a step in the extraction of gelatinous products and is one of the processes in processing donkey hides, the raw material for donkey-hide gelatin. After soaking, the donkey hides are cleaned with sodium carbonate and rinsed with water. Sodium carbonate is mainly used in blanching to remove impurities and soften the hides, ensuring the quality of subsequent processing. The entire blanching process is completed inside a steaming ball. As the steaming ball rotates, the donkey hides are heated and cleaned. After a certain number of cleaning cycles, the blanching water is released through the vent valve at the bottom of the steaming ball, and drinking water is added to continue rinsing until the blanching water is clear and transparent.
[0003] The determination of the endpoint of blanching and washing donkey hide directly affects the subsequent amount of drinking water used and the number of times the hide is washed. Methods for determination include traditional methods and modern technology. Traditional methods rely on manual observation, which is subjective, inefficient, and lacks accuracy. Modern technology currently includes pH detection or the installation of turbidity detection equipment using pH test strips. However, since both drinking water and blanching water are alkaline, the test strips have a wide detection range and cannot accurately determine the endpoint. This method has low sensitivity and still cannot guarantee accurate determination of the washing endpoint, thus failing to reasonably control the amount of drinking water used. Using turbidity detection as an auxiliary method, such as patent application CN119667093A, "A Device and Method for Determining the Cleanliness of Donkey Hide Raw Material Based on Turbidity," involves adding turbidity detection equipment and using a turbidity pipe to connect the turbidity detection equipment to the outlet of the steaming and sludge-removing machine. Because this type of turbidity detection facility is connected to the drain outlet at the bottom of the steaming ball for detection, it affects the drainage and slag removal of the steaming ball to some extent and has the problem of inflexible spatial layout. In addition, the turbidity detection process of this patented technology needs to be carried out after the steaming machine is stopped, which makes it impossible to achieve real-time online monitoring, prolonging the process production cycle and reducing production efficiency. Utility Model Content
[0004] This invention proposes a device for detecting the water content of steamed balls during the blanching process. It can detect the water content in real time online without interfering with the normal operation of the steamed balls. This avoids the problems of difficulty in timely and accurate determination of the endpoint of blanching and washing the skin in current steamed balls, and the waste caused by the inability to reasonably control the amount of drinking water used. Compared with the shortcomings of existing qualitative detection methods that are inaccurate in determining the endpoint of blanching and washing the skin, and existing turbidity detection facilities that require the steamed balls to be stopped for detection, thus prolonging the overall process cycle and interfering with the drainage and slag discharge of the steamed balls when the detection pipeline is laid out, this device effectively solves the problems existing in the prior art.
[0005] This utility model provides the following technical solution:
[0006] A device for detecting the water content of a steamed ball used for blanching includes a frame and a steamed ball rotatably mounted on the frame. A drain pipe is installed inside the steamed ball, and the drain pipe is fixed in the lower space inside the steamed ball when the steamed ball is working or not working. One end of a horizontal pipe is connected to the top of the drain pipe. The horizontal pipe is fitted inside and extends out of a drive shaft on one side of the steamed ball. A detection structure is connected to the other end of the horizontal pipe. The detection structure includes a water quality testing container, an inlet pipe, and a drain pipe. The inlet pipe includes a first pipe section connected to the outlet end of the horizontal pipe and a second pipe section located above the first pipe section. A first valve and a second valve are respectively installed on the first and second pipe sections. The second pipe section is connected to the water quality testing container. The drain pipe is installed at the bottom end of the water quality testing container, and a third valve is installed on the drain pipe.
[0007] Furthermore, the drain pipe is an extension pipe that extends along the arc surface of the lower inner wall of the evaporator, with the bottom end of the extension pipe extending downward to the center of the bottom of the evaporator and the top end of the extension pipe extending upward to connect with the horizontal pipe.
[0008] Furthermore, the horizontal tube is fixedly connected to the extension tube or detachably sealed. The horizontal tube is rotatably sealed to the drive shaft.
[0009] Furthermore, the extension tube extends along the arc surface of the inner wall of the steaming ball and is not in contact with the inner wall of the steaming ball.
[0010] Furthermore, an exhaust port is installed at the top of the water quality testing container.
[0011] Furthermore, the water quality testing container is a sealed container with an exhaust pipe at the top. The exhaust port at the top of the exhaust pipe allows the gas in the blanching water to be tested to be discharged smoothly through the exhaust port.
[0012] Furthermore, a detection probe and a liquid level sensor are installed inside the detection container.
[0013] Furthermore, the detection probe is a conductivity testing probe.
[0014] Furthermore, the detection probe is a conductivity testing probe and a pH meter; or, the detection probe is a conductivity testing probe, a pH meter, and a transmittance detection probe.
[0015] Furthermore, the aforementioned detection probes can be fixed to the top wall of the detection container, and each detection probe is connected to an external detection display screen via a circuit.
[0016] Furthermore, the first, second, and third valves are all automatic shut-off valves or regulating valves.
[0017] Furthermore, both the automatic shut-off valve and the regulating valve are electric or pneumatic valves.
[0018] Furthermore, the opening degree of the second valve is not less than the opening degree of the third valve.
[0019] Furthermore, the detection device also includes a controller, which is electrically connected to the liquid level sensor and each valve. The controller can be a PLC controller. The controller receives the liquid level signal transmitted from the liquid level sensor into the detection container and controls the opening of the second valve to be greater than that of the third valve, maintaining a stable liquid level in the water quality detection container and meeting the detection time requirements. The liquid level sensor prevents liquid from overflowing from the vent in the water quality detection container.
[0020] Furthermore, a steam pipe communicating with the interior of the steaming ball is installed inside the drive shaft on the other side. This pipe facilitates the smooth and normal drainage of the liquid from the drain pipe. Similarly, the steam pipe is sealed and rotatably connected to the drive shaft on this side, ensuring that the normal operation of the steaming ball is not disturbed.
[0021] Furthermore, as an alternative method for draining liquid through the drain pipe, a pump can be installed on the pipeline connected to the water quality testing container to replace the aforementioned steam pipeline.
[0022] The steamed ball blanching water detection device proposed in this utility model can bring the following beneficial effects:
[0023] 1. The steamed ball blanching water detection device has a scientific and reasonable layout, which can smoothly and without interference perform blanching water extraction and detection multiple times while the steamed ball is working, with high online detection efficiency.
[0024] 2. This steaming ball blanching water testing device, by timely measuring the conductivity of the blanching water and potentially further integrating transmittance and pH measurements during production, assists technicians in effectively judging the effect and state of the blanching process, based on adhering to effective monitoring indicators or adding comprehensive testing items. This allows for more accurate and timely determination of the process endpoint, enabling continuous testing, blanching, and drainage, thereby reducing the number of blanching cycles and saving drinking water consumption. Compared to existing qualitative testing methods that are inaccurate in determining the blanching and washing endpoint, and existing turbidity testing facilities that require the steaming ball to be stopped for testing, extending the overall process cycle, and causing interference with steaming ball drainage and slag discharge due to the layout of testing pipelines, this device offers significant advantages.

[0030] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0031] See Figure 1 , Figure 2 This embodiment discloses the structure of the steaming ball blanching water detection device. Specifically, it includes a frame 1 and a steaming ball 2 rotatably mounted on the frame. A steaming ball drain outlet 21 is provided at the bottom of the steaming ball, which is used to discharge a large amount of blanching water after the steaming ball stops. A drain pipe 3 is provided inside the steaming ball. The drain pipe is fixedly suspended in the lower space inside the steaming ball when the steaming ball is working or not working. The drain pipe 3 is an extension pipe extending along the arc surface of the lower inner wall of the steaming ball. The bottom end of the extension pipe extends downward to the center of the bottom of the steaming ball. One end of a horizontal pipe 4 is connected to the top of the extension pipe. The horizontal pipe is housed in the drive shaft on the right side of the steaming ball. That is, the horizontal pipe 4 is completely sealed inside the drive shaft on the right side of the steaming ball. The other end of the horizontal pipe 4 extends out of the drive shaft on this side. A detection structure is connected to the outside of the other end of the horizontal pipe. The detection structure includes a water quality detection container 5, an inlet pipe 6, and an outlet pipe 7. The inlet pipe includes a first pipe section 61 connected to the outlet end of the horizontal pipe and a second pipe section 62 located above the first pipe section. A first valve 8 and a second valve 9 are respectively installed on the first and second pipe sections. The second pipe section is connected to the water quality detection container. The outlet pipe 7 is installed at the bottom end of the water quality detection container, and a third valve 10 is installed on the outlet pipe.
[0032] The first section 61 of the liquid inlet pipe 6 is also the glue discharge pipe for the subsequent skin-melting process, and the first valve 8 on it is used to control the flow rate of glue discharge during the skin-melting process.
[0033] The aforementioned horizontal pipe 4 is either fixedly connected to the extension pipe or detachably sealed. The extension pipe extends along the arc surface of the inner wall of the steaming bulb and is not in contact with the inner wall of the steaming bulb.
[0034] The water quality testing container is a sealed container with an exhaust pipe 11 at the top. The exhaust port at the top of the exhaust pipe allows the gas in the blanching water to be tested to be discharged smoothly through the exhaust port.
[0035] A detection probe 12 and a liquid level sensor 13 are installed inside the aforementioned detection container. The detection probe is a conductivity testing probe.
[0036] In one implementation, the detection probe is a conductivity testing probe and a pH meter. Alternatively, the detection probe is a conductivity testing probe, a pH meter, and a transmittance testing probe.
[0037] The aforementioned detection probes can be fixedly mounted on the top wall of the detection container, and each detection probe is connected to an external detection display screen via a circuit.
[0038] The first, second, and third valves mentioned above are all electric valves. The opening degree of the second valve is not less than the opening degree of the third valve.
[0039] To facilitate drainage from the drain pipe into the water quality testing container, a steam pipe 14 is installed inside the drive shaft on the left side of the steaming ball. This pipe is used to transport steam into the steaming ball and push the blanching water inside to be smoothly discharged through the drain pipe.
[0040] In another implementation, the above detection device can be connected to an external controller, which is electrically connected to the liquid level sensor and each valve. The controller can be a PLC controller, which receives the liquid level signal transmitted from the liquid level sensor into the detection container, and controls the opening of the second valve to be greater than that of the third valve, maintaining a stable liquid level in the detection container and meeting the detection time requirements. The liquid level sensor also prevents liquid from overflowing from the vent in the water quality detection container.
[0041] Taking the installation of a conductivity testing probe inside a water quality testing container as an example, the working process of this device is described. Based on the requirements of the donkey hide blanching process in the preparation of donkey-hide gelatin, the final qualified conductivity is set at 800 μS / cm (example value, generally between 300 μS / cm and 1500 μS / cm). The detection cycle during the blanching process is multiple tests every 10-15 minutes. When the conductivity reading during a single blanching process exceeds 800 μS / cm, the steaming process is stopped, the blanching water is drained, and drinking water is added to repeat the blanching process until the conductivity of the blanching water meets the standard. Then, the steaming process is stopped again, the blanching water is drained, and tap water is added for rinsing. The specific usage process is described below:
[0042] 1. Place the cut and cleaned donkey hide raw material into steaming ball 2, and set the electrical conductivity standard of the cleaned donkey hide to 800μS / cm;
[0043] 2. Add water to the steaming ball to the appropriate amount, add sodium carbonate, turn on the equipment and heat to 50-80℃ for blanching. After 30 minutes, drain the alkaline water; continue to add water for blanching. After each blanching cycle (e.g., 10-15 minutes), there is no need to stop the machine. Prepare to drain the water required for testing from container 5.
[0044] 3. Before discharging the test water, close the third valve 10 and the first valve 8, open the second valve 9, and send steam into the steam ball through the steam pipe 14 set in the drive shaft on the left side of the steam ball. Under the push of the high pressure steam in the steam ball, the blanching water is pressed from the bottom of the steam ball into the drain pipe 3, and then transported to the horizontal pipe 4 and into the second section 62 of the inlet pipe 6 connected to the water quality test container 5. The blanching water is then transported through the second section to the water quality test container that is gradually filled.
[0045] During this process, the liquid level sensor 13 is used to maintain a suitable liquid level in the water quality testing container to prevent overflow.
[0046] 4. Measure the conductivity of the blanching water inside the steaming ball during operation using a conductivity test probe, and record it as the first blanching. Compare it with the standard to determine whether to continue blanching. Open the third valve 10 to drain the blanching water from the water quality testing container.
[0047] 5. With steam pipe 14 and the first and second valves closed, stop the machine and open the drain outlet 21 at the bottom of the steam ball to discharge the blanching water directly without pressurization; based on the conductivity result of the first blanching, add an equal amount of drinking water to the steam ball for a second blanching; repeat the online non-stop testing of the second blanching water as described above; if the test result does not meet the conductivity standard, continue to repeat steps 4 and 5;
[0048] 6. If the test result of the blanching water meets the conductivity standard, the blanching process ends after the steaming machine stops and the blanching water is drained; rinse with drinking water and continue the skin-softening process.

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in sequences other than those illustrated or described herein.
