Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for powder quality analyzers, and in particular to a constant temperature automatic water addition device for powder quality analyzers. Background Technology

[0002] A farinograph is a core instrument for flour quality testing. It evaluates the rheological properties of flour by measuring the changes in resistance during the kneading process. During the test, distilled water at a specific temperature (usually 30±0.2℃) is continuously added to the flour to bring the dough to the standard consistency. This water addition process is crucial to the accuracy and repeatability of the test results.

[0003] Currently, the most common method for adding water in laboratories is manual operation. This involves the experimenter holding a preheated distilled water bottle or syringe, visually observing the dough formation, and manually controlling the amount and speed of water added based on the movement of the instrument pointer. This method is cumbersome and inefficient. Specifically, the experimenter must maintain a high level of concentration throughout the process and manually add water, making it impossible to perform other tasks. The degree of automation is low. Therefore, we propose a constant-temperature automatic water adding device for a farinometer. Utility Model Content

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Reference Figures 1-4 A constant temperature automatic water filling device for a powder analyzer is provided. This constant temperature automatic water filling device for a powder analyzer includes an open constant temperature water tank 1. A water guide pipe 101 is coiled and installed inside the open constant temperature water tank 1. A water outlet 102 and a water inlet 103 are respectively installed at both ends of the water guide pipe 101.

[0027] Frame 2, on which a vertical plate 201 is mounted;

[0028] Water level drive module; The water level drive module includes a float 301, a connecting rod 302, and a lever 303. The float 301 is made of hollow stainless steel and floats on the water surface of the open-type constant temperature water tank 1. One end of the connecting rod 302 is installed on the float 301, and the other end is hinged to one end of the lever 303. The lever 303 is hinged to the vertical plate 201 via a support shaft. The lever 303 is designed with a ratio of 1:3 (displacement of float 301: stroke of piston 402) to ensure that the piston 402 can be driven by slight changes in water level.

[0029] The quantitative water supply module includes a cylinder 401 mounted on the frame 2. The cylinder 401 is made of transparent glass and has a volume of 50mL. A piston 402 is movably installed inside the cylinder 401, and a piston rod 403 is mounted on the piston 402. The end of the piston rod 403 away from the piston 402 is hinged to the other end of the lever 303. A one-way inlet valve 404 and a one-way outlet valve 405 are connected and connected at the bottom of the cylinder 401. The one-way inlet valve 404 is connected to the outlet 102 through a pipe. In application, through the mechanical linkage design of the float 301, lever 303 and piston 402, the automatic water level monitoring and quantitative water supply are synchronously controlled. The water volume can be adjusted according to the water level without manual intervention, solving the problem of inefficiency of manual operation.

[0030] Reference Figure 1 The open-type constant temperature water bath 1 has a connected water inlet 104 and an overflow outlet 105 on its side wall. The water temperature is maintained by an external constant temperature water circulator (usually 30±0.2℃). In application, the setting of water inlet 104 and overflow outlet 105 simplifies the water replenishment and overflow management of the open-type constant temperature water bath 1, ensures the stability of the water volume in the open-type constant temperature water bath 1, and avoids interference with the experiment due to excessively high or low water levels.

[0031] Reference Figure 2 and Figure 3 A sealing ring (nitrile rubber sealing ring) is installed between the piston 402 and the cylinder 401 for sealing. In application, the sealing ring enhances the airtightness between the cylinder 401 and the piston 402, prevents water leakage or pressure loss, and ensures the accuracy and stability of quantitative water supply.

[0032] Reference Figure 3 and Figure 4 Both the one-way inlet valve 404 and the one-way outlet valve 405 are ball check valves. In application, the ball check valve has a simple structure and reliable sealing. It can effectively control the one-way flow of water and avoid water volume errors caused by backflow.

[0033] Reference Figure 3 and Figure 4 A one-way water outlet valve 405 is equipped with a connected water outlet hose 5. The end of the water outlet hose 5 is equipped with a capillary needle 501, which is located above the kneading bowl of the farinograph. The capillary needle 501 is fixed 10cm directly above the kneading bowl of the farinograph to ensure that the water droplets fall vertically into the center of the dough. In application, the design of the capillary needle 501 makes the water flow into fine droplets, which can accurately control the water addition speed, simulate the manual adjustment effect of manual operation, and reduce the water volume fluctuation during the dough kneading process.

[0034] Reference Figures 1-3The water inlet 103 is connected to a water supply bottle 6 through a pipe, and the water supply bottle 6 is located on the frame 2. The water supply bottle 6 is connected to the water inlet 103 through a silicone tube and automatically replenishes water by gravity. In application, the water supply bottle 6 and the frame 2 are integrated into one unit, which facilitates water supply and maintenance, and avoids external water sources from interfering with the temperature of the open constant temperature water tank 1.

[0035] The working principle of this utility model is as follows: Device initialization: Distilled water is injected into the open-type constant temperature water tank 1 to the standard water level line (covering 80% of the area of ​​the water pipe 101), then the constant temperature water circulation equipment is turned on and preheated to the set temperature (such as 30℃), and finally distilled water is added to the replenishment water bottle 6 to remove air bubbles from the pipeline.

[0036] Water level linkage calibration: First, manually adjust the initial position of the float 301 so that the lever 303 is in a horizontal state. Then test the stroke of the piston 402. When the water level drops, the float 301 drives the lever 303 to lift the piston 402 and draw in water. When the water level rises, the lever 303 and the piston 402 reset.

[0037] Experimental Operation: First, start the mixing bowl of the farinograph, put in the flour sample, and then automatically add water. At this time, the water level in the open constant temperature water bath 1 drops due to evaporation, the float ball 301 sinks, the lever 303 raises the piston 402, the one-way inlet valve 404 closes, and the one-way outlet valve 405 opens. Water flows through the capillary needle 501 and drips into the mixing bowl. When the water level recovers, the float ball 301 floats up, the lever 303 and piston 402 return to their original positions, and new water is drawn in. The one-way outlet valve 405 closes. During this period, the overflow port 105 automatically discharges excess water to maintain a constant water level.

[0038] End and maintenance: After the experiment, turn off the constant temperature water circulation equipment, empty the open constant temperature water tank 1 and the replenishment water bottle 6, then disassemble the capillary needle 501 for cleaning to prevent blockage, and check the wear of the sealing ring.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
