Description

Technical Field

[0001] The utility model relates to the technical field of reagent filling, and specifically relates to a reagent quantitative filling device. Background Art

[0002] Magnesium silicate is an inorganic substance with the chemical formula MgSiO3, a molecular weight of 100.3887, and white to grayish-white fine powder. It has a small content in nature and can only appear in large amounts in the components of silicate minerals. Magnesium silicate is widely used in industries such as food, chemical industry, medicine, and environmental protection, becoming an important adsorption material. Industrially, magnesium silicate is widely used in the treatment of wastewater and waste gas in fields such as petroleum, chemical industry, and food processing; in life, magnesium silicate materials can be used to remove oil stains and harmful substances in electrical appliances such as range hoods and water purifiers. Magnesium silicate is a natural mineral, and its adsorption principle is to adsorb target substances using its microporous structure and surface charge characteristics. Magnesium silicate can effectively adsorb various harmful oil substances such as unsaturated fatty acids, triglycerides, and cholesterol, removing some pollution sources in industry and life.

[0003] There is a current oil-in-water extractor that needs to use magnesium silicate to adsorb animal oil in water. Because the filling port is too small, it is necessary to continuously fill it quantitatively and use a filling device for filling. However, since most magnesium silicate reagents are in powder form, during the quantitative process, the powder is prone to clogging under the action of friction and cannot fall normally. Therefore, we have proposed a new filling device. Content of the Utility Model

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0027] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] In the related art, most magnesium silicate reagents are in powder form. During the quantitative process, the powder is easily blocked due to friction and cannot fall normally.

[0029] In order to solve the problems in the related art to a certain extent, an embodiment of the present application provides a reagent quantitative filling device. When it is needed, it is only necessary to set a knocking component 3 next to the filling component 2. When the magnesium silicate powder passes through the silicone tube 22, the silicone tube 22 is continuously knocked to avoid blockage of the magnesium silicate.

[0030] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0031] Combination Figures 1 - 3, an embodiment of the present application provides a reagent quantitative filling device, including a filling assembly 2; the filling assembly 2 includes: a container 21 is arranged on the top of the water-in-oil extractor box body 1; a filling port 23 is arranged on the inner wall of the water-in-oil extractor box body 1; a silica gel tube 22 connects the container 21 and the filling port 23; an extrusion valve 24 is arranged on the inner wall of the water-in-oil extractor box body 1; a knocking assembly 3 is arranged on the inner wall of the water-in-oil extractor box body 1, and a support plate 31 of the knocking assembly 3 is arranged on the inner wall of the water-in-oil extractor box body 1; a motor 32 is arranged on the top of the support plate 31; a ratchet 33 is arranged on the output end of the motor 32; a fixed seat 34 is arranged on the inner wall of the water-in-oil extractor box body 1; a knocking rod 35 is connected to the fixed seat 34 through a torsion spring mechanism.

[0032] When in use, pour magnesium silicate powder on the container 21, and then it drops down along the silica gel tube 22. The extrusion valve 24 blocks the falling of the magnesium silicate powder by extruding the silica gel tube 22. The extrusion valve 24 extrudes the silica gel tube 22, and the extruded part of the silica gel tube 22 deforms, and the middle channel is blocked, so that the magnesium silicate powder cannot continue to fall. Loosing the silica gel tube 22 allows it to continue falling. The extrusion valve 24 periodically extrudes and releases the silica gel tube 22 to achieve quantitative filling of the magnesium silicate powder, and then it falls into the filling port 23. The motor 32 drives the ratchet 33 to rotate. The knocking rod 35 is rotationally connected to the fixed seat 34 through a torsion spring structure. As the ratchet 33 rotates, the knocking rod 35 is continuously toggled. Subsequently, the knocking rod 35 resets with the help of the torsion spring structure, and at the same time knocks the silica gel tube 22 to prevent the magnesium silicate powder inside from being blocked due to friction and shake down the magnesium silicate powder in the silica gel tube 22. Especially, the shape recovery of the extruded part of the silica gel tube 22 is slower and it is more likely to be blocked. The ratchet 33 is always in a rotating state, causing the knocking rod 35 to continuously knock the silica gel tube 22.

[0033] Specifically, the container 21 is a container made of glass structure.

[0034] Specifically, the oil-in-water extractor belongs to the prior art and is not shown in detail in the attached drawings. It mainly includes the following structures: an extraction bottle (used to contain water sample and extractant, usually with a certain capacity and scale), a stirring device (used to stir the water sample and extractant to promote full mixing of the two and improve the extraction efficiency), a heating device (used to heat the water sample and extractant to improve the extraction efficiency), a separation device (used to separate the organic phase and the aqueous phase, usually using a separatory funnel or a centrifuge and other equipment), a collection device (used to collect the organic phase after extraction, usually using a volumetric flask or a colorimetric tube and other equipment), a control system (used to control the operation of the extractor, including temperature, stirring speed, extraction time and other parameters). The water sample and the organic extractant are added to the extraction bottle respectively, and it is careful not to exceed the capacity of the extraction bottle. The stirring device is started to fully mix the water sample and the extractant until a certain extraction time. The stirring device is turned off and separated by a separatory funnel or filter paper. The separated organic solvent is collected in a collection device, usually using a volumetric flask or a colorimetric tube, etc. The collected organic solvent is analyzed, usually using an infrared spectrophotometer or an ultraviolet spectrophotometer, etc., to determine the oil content therein. Finally, the extraction bottle and other related equipment are cleaned for next use.

[0035] In some embodiments, the outer side wall of the knock rod 35 is provided with a protrusion 36 that cooperates with the ratchet 33. The setting of the protrusion 36 cooperates with the ratchet 33 to better move the knock rod 35.

[0036] In some embodiments, the inner wall of the oil-in-water extraction instrument housing 1 is provided with a protective cover 37 , and the protective cover 37 contains the knocking rod 35 and the motor 32 . The protective cover 37 protects the motor 32 and the knocking rod 35 .

The silicone tube 22 passes through the housing 241, and the extension rod of the electric push rod 242 moves forward to squeeze the silicone tube 22.

[0038] In some embodiments, an extrusion block 243 is disposed at the output end of the electric push rod 242. The extrusion block 243 can better extrude the silicone tube 22.

[0039] In some embodiments, the outer wall of the oil-in-water extraction instrument housing 1 is provided with a fixing groove 25 for matching the extrusion valve 24. The extrusion valve 24 is stuck in the fixing groove 25 and can be removed for maintenance and replacement at any time after the silicone tube 22 is pulled out.

[0040] In some embodiments, a fixing block 26 is provided at one end of the extrusion valve 24, and the fixing block 26 is connected to the water-in-oil extractor box body 1 by bolts 27. The extrusion valve 24 is fixed to the water-in-oil extractor box body 1 through the bolts 27 on the fixing block 26, increasing stability.

[0041] In some embodiments, the number of the extrusion valves 24 is two, and the knocking rod 35 is located between the extrusion valves 24. The extrusion valves 24 are arranged in two and regularly loosen and close the silica gel tube 22, better quantitatively filling magnesium silicate, providing double insurance, avoiding mistakes, reducing filling errors.
