Description

Technical Field

[0002] Humic acid is a macromolecular organic substance widely found in nature and widely used in agriculture, forestry, animal husbandry, petroleum, chemical industry, building materials, medicine and health, environmental protection and other fields. Dissolution rate is one of the main quality indicators for sensory evaluation of humic acid products, but there is no specific determination method and device for the dissolution rate of humic acid products. Customers tend to choose humic acid products with faster dissolution rate. At present, the determination of humic acid products in most cases still chooses to take an appropriate amount of sample and pour it into water, then observe its dissolution with the naked eye, and record the dissolution time as a basis for judgment; the above observation method has increased errors, and its errors mainly come from subjective errors and objective errors. Taking subjective errors as an example: since dissolution requires a certain process, the observer will end the timing before or after the end of dissolution, resulting in errors in the dissolution time; taking objective errors as an example: when the sample is manually poured into the beaker, the pouring angle and pouring speed (the amount of humic acid entering at one time) will affect the determination of the dissolution rate; and the above pouring angle and pouring speed are not easy to control, so there are errors. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Reference Figure 1-4 As shown, the utility model provides a device for measuring the dissolution rate of a humic acid product, the device includes a beaker 1 for dissolving the humic acid product, the device at least includes a conductivity meter 2 adapted to the beaker 1 and a humic acid dissolution unit provided on the beaker 1 for achieving uniform dissolution of the humic acid product; the humic acid dissolution unit includes a dissolution chamber 3, a cover plate 4 provided on the top of the dissolution chamber 3, and a plurality of dissolution holes 5 provided on the side wall of the dissolution chamber 3. The utility model determines whether the humic acid product is completely dissolved by providing a conductivity meter 2 to measure the conductivity of the solution, thereby avoiding the problem of subjective misjudgment by the operator. Furthermore, the conductivity meter 2 described in the utility model can try to detect the conductivity, and determine the dissolution trend of the humic acid product according to the conductivity data; the utility model sets a dissolution chamber 3 to avoid the purpose of detection being affected by the inability to maintain uniform operation; in actual use, the humic acid product is placed into the dissolution chamber 3 through the top of the dissolution chamber 3, the cover plate 4 is closed, and the dissolution chamber 3 is placed in the dissolution chamber 3. The solution enters the dissolving cavity 3 and slowly dissolves with the humic acid product, and is released into the beaker 1 through the dissolving hole 5. The above process can achieve uniform dissolution of the humic acid product, and avoid the characteristics of too much or too little humic acid product entering the beaker 1 at one time, which affects the dissolution rate of the humic acid product. In addition, even if a very small amount of humic acid product falls out of the dissolving hole, it will eventually fall into the beaker, so the impact on the measurement result can be ignored (the essence of setting the dissolving cavity 3 in the utility model is to enable the process of adding the humic acid product to the solution to achieve the purpose of standard and repeatable operation).

[0021] Furthermore, the dissolving chamber 3 and the cover plate 4 are connected by a hinge, and a sealing gasket 6 is fixedly provided around the top of the dissolving chamber 3. The sealing gasket 6 is fixedly provided around the top of the dissolving chamber 3 described in the utility model, which can achieve the sealing between the dissolving chamber 3 and the cover plate 4, and avoid the problem that the solution enters and exits therefrom, thereby affecting the dissolving speed; the above arrangement can improve the accuracy of detecting the dissolving speed of the humic acid product.

[0022] Furthermore, a lifting member capable of lifting and lowering the dissolving chamber 3 is provided at the rear of the dissolving chamber 3, and the lifting member comprises a slideway, and a slide bar 7 capable of moving up and down is provided inside the slideway, and the slide bar 7 is connected to the outer wall of the dissolving chamber 3 through a connecting block 8. The dissolving chamber 3 described in the utility model is connected to the slide bar 7 through the connecting block 8, and the slide bar 7 can move up and down inside the slideway, thereby realizing the up and down movement of the dissolving chamber 3; that is, when the humic acid product needs to be placed, the dissolving chamber 3 is placed above the liquid surface, and when the humic acid product needs to be dissolved, the dissolving chamber 3 is placed below the liquid surface, so as to achieve the purpose of facilitating dissolution.

[0023] Furthermore, the slide includes a back plate 9, and a left slide 10 and a right slide 11 arranged on the left and right sides of the back plate 9, and the inner sides of the left slide 10 and the right slide 11 are provided with slide grooves, and the two sides of the slide bar 7 are adapted to the slide grooves, and the lower part of the slide bar 7 is connected to the outer wall of the dissolution chamber 3 through the connecting block 8.

[0024] Furthermore, a plurality of pin holes 12 are evenly distributed on both sides of the slide bar 7. By providing a plurality of pin holes 12, the dissolution chamber 3 can be easily fixed. When the dissolution chamber 3 is moved to a suitable position, the pin is inserted into the pin hole 12, and the top of the left slide 10 and the right slide 11 are used as the limit to fix the slide bar 7, thereby fixing the dissolution chamber 3.

[0025] The utility model also includes a fixing unit, which includes a fixing plate 13 and a bracket 14 arranged at the bottom of the fixing plate 13; a conductivity cathode 15 and a conductivity anode 16 are arranged on the conductivity measuring instrument 2; and a conductivity cathode hole, a conductivity anode hole and a lifting member clamping groove are arranged on the fixing plate 13. Through the above arrangement, the conductivity cathode 15, the conductivity anode 16 and the lifting member can be fixed, thereby achieving the purpose of reducing labor intensity and the number of operators.

[0026] Furthermore, a water bath heater 17 is provided at the bottom of the beaker 1. The water bath heater 17 can be provided to control the temperature in the beaker 1, so as to detect the influence of different temperatures on the dissolution rate of the humic acid product.

[0027] The working principle of the utility model comprises the following steps: weighing a certain amount of water and putting it into a beaker 1, and putting the beaker 1 into a water bath heater 17, starting the water bath heater 17 to heat the water in the beaker 1, and making the water in the beaker 1 at a preset temperature, manually opening the cover plate 4 to put the weighed humic acid product into the dissolving chamber 3, and closing the cover plate 4 (to make it well sealed); after preparation, manually moving the slide bar 7 downward along the slide grooves on the inner sides of the left slide 10 and the right slide 11 to below the water surface, and turning on the conductivity meter 2; the conductivity meter 2 measures the conductivity of the dissolution through the conductivity cathode 15 and the conductivity anode 16; in the actual detection process of the conductivity meter 2, the time can be accurate to 0.1 second, and during the dissolution process, observe the change of conductivity on the trend display diagram on the conductivity meter 2, and when the conductivity value tends to be stable (the change rate is less than 5% within 3 seconds), the dissolution rate measurement is ended, the test is stopped, and the corresponding data is recorded.
