Description

Technical Field

[0001] This application relates to the field of equipment testing technology, and in particular to a mixer load life testing device. Background Technology

[0002] In existing technologies, load-bearing life testing of household or commercial blenders typically requires long-term, continuous operation to verify their reliability under simulated daily use environments or extreme conditions. However, traditional testing methods are often limited to the following: running each blender under test individually under load, using real ingredients or certain simulated media for blending tests. Because this requires repeatedly adding ingredients and running for extended periods, operators must frequently change or add test materials, resulting in high labor intensity. Furthermore, real ingredients are highly susceptible to spoilage or decay after prolonged testing, making them unusable and leading to resource waste and increased costs. Simultaneously, spillage of broth or food during testing, as well as equipment cleaning and maintenance, are cumbersome and inefficient. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a mixer load life testing device, which can simplify the operation process of mixer load life testing and reduce the intensity of manual intervention and resource consumption.

[0004] A mixer load life testing device according to an embodiment of this application includes: a support frame for supporting a plurality of mixers to be tested; a circulation pipeline system including a storage tank, a test liquid circulation loop, and a cooling circulation loop; the storage tank storing test liquid; the test liquid circulation loop connecting the storage tank and the mixer container of the mixer to be tested; the test liquid circulation loop for transporting the test liquid to the mixer container and continuously refreshing the test liquid in the mixer container; and the cooling circulation loop connected to the storage tank for cooling the test liquid.

[0005] The mixer load life testing device according to the embodiments of this application has at least the following beneficial effects: The circulation pipeline system includes a test liquid circulation loop and a cooling circulation loop, which can circulate the test liquid between the mixer container and the storage tank, and cool the test liquid through the cooling circulation loop. The recycling of the test liquid not only reduces the consumption of the test liquid and lowers the testing cost, but also avoids the resource waste problem caused by test liquid waste in traditional testing. At the same time, the test liquid circulation loop can continuously refresh the test liquid in the mixer container, avoiding the tedious operation of frequently manually changing the test liquid in traditional testing, further improving the automation level of the testing process. The cooling circulation loop exchanges heat with the test liquid through a heat exchanger, effectively reducing the temperature of the test liquid and preventing the test results from being affected by excessively high test liquid temperature due to prolonged mixer operation, thereby ensuring the stability and reliability of the test.

[0006] According to some embodiments of this application, the test liquid circulation loop includes: a mixer inlet pipe, a mixer return pipe, and a delivery pump. The mixer container has a mixer inlet and a mixer overflow. The mixer inlet pipe is connected in sequence to the storage tank, the delivery pump, and the mixer inlet. The mixer return pipe is connected in sequence to the mixer overflow and the storage tank.

[0007] According to some embodiments of this application, the cooling circulation loop includes a cooling water pipe, a cooling circulation pump, and a heat exchanger. The cooling water pipe is connected in sequence to the liquid storage tank, the cooling circulation pump, and the heat exchanger and returns to the liquid storage tank. The heat exchanger is used to cool the test liquid by heat exchange.

[0008] According to some embodiments of this application, it also includes a plurality of mixer trays, which are disposed on the support frame. The mixer to be tested is disposed in the mixer tray, and the mixer tray corresponds one-to-one with the mixer to be tested. The mixer tray is used to collect the test liquid that overflows during the test.

[0009] According to some embodiments of this application, the circulation pipeline system further includes an overflow circuit, and the bottom of the mixer tray is provided with a tray overflow port. The overflow circuit connects the tray overflow port to the water storage tank so that the overflowed test liquid can flow back into the storage tank.

[0010] According to some embodiments of this application, each of the mixer inlet pipes is further provided with an electrically controlled valve, which is used to individually control the inlet channel of the test liquid to the corresponding mixer under test, so as to shut off the inlet of the corresponding mixer when some of the mixers under test malfunction or need to suspend the test.

[0011] According to some embodiments of this application, the test solution is a mixed medium containing preservatives and with adjustable viscosity.

[0012] According to some embodiments of this application, the support frame has multiple layers, including: an equipment control layer, a test station layer, and a circulation system layer arranged sequentially from top to bottom. The equipment control layer is used to set up the power supply and switching equipment of the mixer load life test device, the test station layer is used to support the mixer under test, and the circulation system layer is used to accommodate the circulation pipeline system.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0026] like Figure 1 and Figure 2As shown, this application mainly includes a support frame 100 and a circulation pipeline system 200 disposed on the support frame 100. The circulation pipeline system 200 includes a liquid storage tank 210, a test liquid circulation loop 220, and a cooling circulation loop 230, etc., for conducting continuous load-bearing life tests on the mixers. The support frame 100 is used to support several mixers under test and the circulation pipeline system 200. For example, the support frame 100 can be reasonably designed as a multi-layer or single-layer structure according to the number and size of the mixers under test, so as to facilitate the simultaneous placement of multiple mixers and ensure that the pipelines and the liquid storage tank 210 can be accommodated within the support frame 100 or the bottom area. The liquid storage tank 210 is disposed below or inside the support frame 100 and is used to store recyclable test liquid. The test liquid can be water or other simulated media with a certain viscosity to simulate actual mixing conditions in different test environments. The liquid storage tank 210 is usually designed as a closable or semi-closable structure to keep the liquid clean while facilitating filling, discharge, and maintenance. The test solution circulation loop 220 connects the storage tank 210 and the mixer container 400 of the mixer under test. The test solution circulation loop 220 is used to transport the test solution into the mixer container 400 and continuously refresh the test solution in the mixer container 400. The cooling circulation loop 230 is connected to the storage tank 210 and is used to cool the test solution.

[0027] The mixer load life testing device in this embodiment continuously delivers and cools the medium within the mixer container 400 through a test liquid circulation loop 220 and a cooling circulation loop 230, thus ensuring the stability and efficiency of load life testing for multiple mixers. Because this device does not rely on frequent manual liquid changes and can cool the test liquid in real time, it significantly improves the automation level of the testing process.

[0028] Understandable, such as Figure 3As shown, the test liquid circulation loop 220 includes: a mixer inlet pipe 221, a mixer return pipe 222, and a delivery pump 223. Each mixer container 400 has an inlet and an overflow outlet on its outer wall; the inlet connects to the mixer inlet pipe 221, and the overflow outlet connects to the mixer return pipe 222. The storage tank 210 has an outlet on its bottom or side wall, connected to the inlet port of the delivery pump 223; the outlet port of the delivery pump 223 is connected to the inlet pipe 221 of each mixer via a main pipe or branch pipe. Thus, when the delivery pump 223 is turned on, the test liquid can be delivered from the storage tank 210 to the interior of each mixer container 400. The mixer inlet pipe 221 extends from the outlet of the delivery pump 223 to the inlet of the corresponding mixer container 400. It can typically be equipped with an adjustable flow rate or an electric valve to individually control the inlet channel of the test liquid to the corresponding mixer under test. This allows for shutting off the inlet of the corresponding mixer when some mixers malfunction or when testing needs to be paused. The mixer return pipe 222 is connected to the overflow port of the mixer container 400, with the other end returning to the same storage tank 210, enabling the recovery and recycling of the test liquid.

[0029] When the delivery pump 223 starts, the test liquid enters the mixer container 400 through the mixer inlet pipe 221. When the container reaches the set liquid level, the overflowing test liquid flows back to the storage tank 210 through the mixer return pipe 222. This cycle repeats continuously, ensuring a stable testing environment during long-term testing and avoiding frequent manual replenishment or draining. Through this arrangement, the test liquid circulation loop 220 provides a stable liquid medium to the mixer container 400 and recovers overflowing test liquid, reducing waste and operational burden.

[0030] Understandable, such as Figure 4As shown, the cooling circulation loop 230 includes a cooling water pipe 231, a cooling circulation pump 232, and a heat exchanger 233. A cooling circulation inlet and outlet pipe is pre-installed on the storage tank 210, one end of which is connected to the suction port of the cooling circulation pump 232, and the other end is connected to the return outlet of the heat exchanger 233, forming a complete circulation path for the cooling water pipe 231. The cooling circulation pump 232 is positioned between the storage tank 210 and the heat exchanger 233 to draw the test liquid from the storage tank 210 and transport it to the heat exchanger 233 for heat exchange. This pump can operate intermittently or continuously according to testing requirements and temperature sensor signals, providing stable cooling capacity for the test liquid. The heat exchanger 233 is located on the return pipe between the cooling circulation pump 232 and the storage tank 210, and is connected to an external industrial chiller 234 (or other refrigeration device) to achieve heat exchange between the test liquid and the coolant. After being cooled by heat exchanger 233, the test liquid flows back to the storage tank 210, ensuring that the overall temperature of the storage tank 210 does not become excessively high due to prolonged operation. During the test, if the test liquid accumulates high temperatures due to prolonged high-speed operation of the mixer, the cooling circulation pump 232 can be activated to draw the heated test liquid from the storage tank 210 and push it into the heat exchanger 233 to exchange heat with the cooling medium, before finally flowing back to the storage tank 210. This maintains the temperature of the test liquid within a suitable range without altering its original composition, thereby stabilizing the load life test results and protecting the mixer components from overheating.

[0031] Understandable, such as Figure 1 and Figure 2 As shown, the mixer load life testing device of the embodiment may further include several mixer trays 300. Each mixer tray 300 is set on the test station layer of the support frame 100 and is used to place and fix the mixer to be tested. The mixer to be tested is placed on the mixer tray 300 for testing. However, if the test liquid is spilled or overflowed, the mixer tray 300 can effectively collect it, avoiding the leakage of liquid from affecting other electrical equipment in the whole device, and at the same time making the test environment cleaner.

[0032] Furthermore, such as Figure 4As shown, the circulation pipeline system 200 also includes an overflow circuit 240. The bottom of the mixer tray 300 is equipped with a tray overflow port, and the overflow circuit 240 connects the tray overflow port to the water storage tank. The mixer tray 300 has an overflow port on its bottom surface or near the bottom surface, allowing for natural overflow when the liquid level in the tray exceeds the bottom height. Branch pipes from multiple tray overflow ports can be combined into a main circuit, using gravity or a small-flow pump to return the overflow liquid to the storage tank 210. When any mixer tray 300 leaks, such as an accidental leak from the mixer container 400 or a large overflow, the excess test liquid will directly enter the overflow circuit 240 through the tray overflow port and then return to the storage tank 210. This not only reduces test liquid waste but also effectively prevents excessive accumulation of overflow liquid in the tray, avoiding soaking the mixer base or other electrical components, thus improving the safety and maintainability of the entire device.

[0033] Understandably, the test solution used in the mixer load life testing device of the embodiment is a mixed medium containing preservatives and with adjustable viscosity. To adapt to the mixing effect of household electric food mixers under different loads, testers can add appropriate amounts of preservatives, thickeners, or other auxiliary formulations to water or damping fluid. On the one hand, this prevents the test solution from deteriorating and spoiling during long-term testing, ensuring the cleanliness and stability of the medium; on the other hand, it allows for the simulation of various food components (such as pastes, thinner liquids, etc.) by increasing or decreasing viscosity according to the testing purpose, making the test results more consistent with the requirements of the actual use environment. When the testing cycle is long, the mixed medium can be monitored and adjusted periodically to maintain its viscosity and anti-corrosion properties, ensuring the repeatability and reliability of simultaneous testing of multiple devices.

[0034] In some embodiments, such as Figure 1 As shown, the support frame 100 has multiple layers, including an equipment control layer, a testing station layer, and a circulation system layer arranged from top to bottom. The top layer is the equipment control layer, which can house electrical equipment such as control boxes and industrial control touch screens, preventing damage to the control unit caused by test fluid leakage. The middle layer is the testing station layer, used to place and fix several mixers to be tested. Each mixer is supported by independent mixer trays 300 or fixed seats, simplifying operation. The bottom layer is the circulation system layer, used to house the water storage tank, water pump, heat exchanger 233, and corresponding pipeline routing, facilitating the storage, transportation, and installation and connection of the cooling device for the test fluid. The multi-layer design achieves functional zoning within a limited space, simplifying the operation process for personnel and facilitating later maintenance and repair.

[0035] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
