Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] refer to Figures 1-4 This utility model provides the following two technical solutions:

[0024] First embodiment: A vegetable heavy metal detection and alarm device, including a support frame 1, the support frame 1 is connected to an adjustment component for vegetable heavy metal detection adjustment, the adjustment component includes: a detection component 2, installed on the support frame 1 for vegetable heavy metal detection and alarm; a filter plate 3, installed on the support frame 1 for providing support for a container containing vegetable solution; a cleaning component 5, installed on the support frame 1 for cleaning and drying the detection end inside the detection component 2; and a treatment component 4, installed on the support frame 1 for supplying water to the cleaning component 5 and collecting and purifying the residual cleaning water, and facilitating the replacement of the purification end;

[0025] The detection component 2 includes a detection probe 23 for detecting heavy metal content in a vegetable solution. A lifting plate 22 is provided on the outside of the detection probe 23. An electric push rod assembly 21 for adjusting the height of the lifting plate 22 is vertically installed on the top of the support frame 1. A controller 24 electrically connected to the detection probe 23 and equipped with a built-in alarm is provided on the rear top of the support frame 1. The cleaning component 5 includes a second liquid pump 51 installed on the rear side of the support frame 1 and supplied with water by the treatment component 4. A conduit 52 is installed on the upper drain end of the second liquid pump 51. An air pump 56 is installed on the rear side of the support frame 1. An exhaust end of the air pump 56 is installed with a... A heating shell 57 is used to convert air into hot gas. A branch pipe 58 is installed on the top of the heating shell 57. Both the conduit 52 and the branch pipe 58 are fixedly connected to a second three-way valve 53 for switching the direction of water supply and gas supply. A connecting pipe 54 is provided on the front side of the second three-way valve 53. A cleaning ring 55 is installed on the support frame 1 near the detection element 2 and the filter plate 3, and is fixedly connected to the connecting pipe 54. The inner wall of the cleaning ring 55 is provided with several spray holes for cleaning and drying the detection end of the detection element 2. The cleaning ring 55 is located directly below the detection probe 23, and the cleaning ring 55 and the detection probe 23 are on the same axis.

[0026] The air pump 56 has a filter with an internal activated carbon mesh installed at its suction end to filter impurities in the air. The cleaning ring 55 is hollow and connected to the connecting pipe 54 and the injection hole. The heating shell 57 has a heating wire built in for heating the air. The processing component 4 includes a liquid storage component 45 installed at the bottom of the support frame 1 to receive filtered water from the filter plate 3 and to supply water to the cleaning component 5. A first liquid pump 41 for drawing the filtered water is installed on the left side of the support frame 1. The suction end of the first liquid pump 41 is equipped with a manual valve 42 connected to the liquid storage component 45. The top of the first liquid pump 41 is equipped with a first three-way valve 43 for switching the injection direction of the pumped water. Both sides of the first three-way valve 43 are equipped with filter tanks 44 with built-in sepiolite filling layers for adsorbing heavy metals in the water. Sepiolite is a natural fibrous magnesium-containing hydrated silicate clay, which has a good adsorption effect on heavy metals in wastewater. Sepiolite has a good adsorption effect on Ni2+, Co2+, Pb2+, Cu2+ and Cd2+ in water, especially for high concentrations of heavy metals.

[0027] After the detection probe 23 completes the detection of the vegetable solution, the height of the detection probe 23 is adjusted by the electric push rod assembly 21 and the lifting plate 22 so that the end of the detection probe 23 to be cleaned is inside the cleaning ring 55. The second liquid pump 51, the conduit 52, the second three-way valve 53, the connecting pipe 54, the cleaning ring 55, the air pump 56, the heating shell 57, the branch pipe 58, and the liquid storage device 45 work together to spray and clean the detection probe 23 and dry it. The spray water is received by the receiving end of the liquid storage device 45 through the filter plate 3. The first liquid pump 41, the manual valve 42, the first three-way valve 43, and the two sets of filter tanks 44 work together to realize the circulation and purification of the liquid receiving end in the liquid storage device 45.

[0028] The main difference between the second implementation method and the first implementation method is that:

[0029] The liquid storage component 45 includes a receiving shell 451 installed at the bottom of the support frame 1 and located below the filter plate 3. The lower left end of the receiving shell 451 is fixedly connected to the manual valve 42. The upper left end of the receiving shell 451 is equipped with two sets of return pipes 452 that are fixedly connected to two sets of filter tanks 44 respectively. The two sides of the filter tanks 44 are fixedly connected to the return pipes 452 and the first three-way valve 43 respectively through flanges. The receiving shell 451 is equipped with a liquid level sensor and a liquid heavy metal concentration sensor for detecting liquid level and liquid heavy metal concentration respectively. The rear side of the support frame 1 is equipped with a water storage shell 454 with built-in clean water for supplying water to the cleaning component 5. The top of the water storage shell 454 is equipped with a water inlet pipe and a cap is installed on the top of the water inlet pipe.

[0030] A water-drawing pipe 455, fixedly connected to the water-drawing end of the second liquid pump 51 inside the cleaning component 5, is installed on the top of the water storage shell 454. A solenoid valve 453, fixedly connected to the water storage shell 454 for water replenishment, is installed on the rear side of the receiving shell 451. The receiving shell 451 receives the water filtered off the filter plate 3, and the water storage shell 454, in conjunction with the water-drawing pipe 455, provides a water source for the second liquid pump 51. During the process of the water storage shell 454 being pumped by the first liquid pump 41 and the manual valve 42, the liquid heavy metal concentration sensor detects the concentration of heavy metals in the liquid. The concentration of heavy metals is tested. When the concentration of heavy metals in the liquid no longer decreases, it means that the sepiolite filling layer in the filter tank 44 is saturated. The first three-way valve 43 is then switched. At this time, the circulating liquid is introduced into the receiving shell 451 through another set of filter tanks 44 and return pipe 452. The original filter tank 44 is replaced by disassembling the flange. After the water in the receiving shell 451 is purified, when the water in the water storage shell 454 is insufficient, the solenoid valve 453 is opened. At this time, the purified water in the receiving shell 451 is introduced into the water storage shell 454 through the solenoid valve 453.

[0031] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0032] In use, the user places the container containing the vegetable crushed solution to be tested under the cleaning ring 55, and adjusts the height of the lifting plate 22 and the detection probe 23 by the electric push rod assembly 21 so that the detection probe 23 enters the container through the cleaning ring 55. The controller 24 is then turned on, and the controller 24 detects the heavy metal content in the solution through the detection probe 23. When the heavy metal content in the solution exceeds the standard, the alarm on the upper side of the controller 24 will sound. The detection probe 23 and the controller 24 used to detect the heavy metal content in the vegetable solution are existing technologies, so their internal structure and working principle will not be described in detail. After the test is completed, the detection probe 23 is separated from the container and its detection end is placed inside the cleaning ring 55.

[0033] The second liquid pump 51 is started, drawing clean water from the water storage tank 454 through the water suction pipe 455. The water then flows through the conduit 52, the second three-way valve 53, the connecting pipe 54, and the spray nozzles on the inner wall of the cleaning ring 55, spraying and cleaning the surface of the detection probe 23. After the detection probe 23 is cleaned, the second liquid pump 51 is turned off, the second three-way valve 53 is reversed, power is supplied to the heating wire in the heating shell 57, and the air pump 56 is turned on. The air pump 56 draws in outside air through a filter, which is then converted into hot air by the heating shell 57 and blown and dried onto the surface of the detection probe 23 through the branch pipe 58 and the cleaning ring 55. During the process, the sprayed water falls into the receiving shell 451 after passing through the filter plate 3. The liquid level sensor and the liquid heavy metal concentration sensor in the receiving shell 451 detect the water level and the concentration of heavy metals in the liquid. When the liquid level in the receiving shell 451 reaches a suitable level and the liquid contains heavy metals, the manual valve 42 and the first liquid pump 41 are opened. The first liquid pump 41 draws the solution in the receiving shell 451 through the manual valve 42. Then the liquid flows back into the receiving shell 451 through the first three-way valve 43, the filter tank 44, and the return pipe 452. When the liquid passes through the filter tank 44, the sepiolite filling layer in the filter tank 44 adsorbs the heavy metals in the liquid.
