Description

Instrument for dropping reagent

Technical Field

The utility model relates to a liquid filling instrument.

Background

When liquid is filled into the tank from the container, the liquid is directly poured and easily spills outside the tank, and a funnel can be generally adopted for assisting pouring. However, the common funnel has a simple structure, the pouring speed is difficult to control, and the adverse phenomena of spilling, splashing and the like are easy to occur during pouring.

The existing liquid preparation process of an injection product of the applicant enterprise is as follows: weighing the injection water in a specified amount by times, pumping into a liquid preparation tank, starting a mechanical stirrer and jacket cooling water, controlling the injection water in the liquid preparation tank within a certain temperature range, pouring a sufficient amount of one raw material into the liquid preparation tank, stirring, and slowly adding a second solution during the stirring to adjust the pH value. When the original post is actually operated, the second solution is prepared in the beaker, and then the beaker is held by a post operator to slowly pour into the liquid preparation tank at the open hand hole. The operation is not strict, the existing operation staff in the batching post have different modes and speeds of pouring the solution, so that the great risk of unstable quality exists, and in addition, the toxic and corrosive liquid is manually operated for a long time, so that the potential safety hazard of the human body also exists.

Disclosure of Invention

Utility model purpose:

provides a device for dripping reagent, which is convenient for inserting and positioning and is not easy to splash and leak liquid.

The technical scheme is as follows:

the utility model discloses an utensil is used in reagent dropwise add can insert dropwise add reagent in the hand hole of dropwise add container (treat dropwise add container if join in marriage the entry of fluid reservoir, for short hand hole), according to the flow top-down of dropwise add reagent, has hourglass hopper-shaped cup body, dropping liquid pipe upper segment, ball valve (can regulate and control the volume of dripping of reagent), dropping liquid pipe hypomere (the central axis of dropping liquid pipe upper segment and hypomere coincides basically) in proper order.

The outer wall of the lower section of the dropping liquid pipe is connected with a circular cover plate, a hole which is sleeved with the lower section of the dropping liquid pipe is reserved in the center of the circular cover plate, and the outer diameter of the circular cover plate is larger than the aperture of the hand hole. Due to the blocking of the circular cover plate, the dropping cup cannot fall into the container or the dropping pipe is prevented from extending into the container too long, and the dropping cup cannot contact with an internal reagent to pollute the outer wall of the dropping pipe.

If the hand hole on the container and the horizontal plane form an inclination angle (angle theta) of 0-45 degrees, in order to enable the body of the dropping cup to contain more reagents, the dropping effect is in a relatively good state, and the dropping liquid pipe is required to be basically arranged in a plumb manner; in order to enable the circular cover plate to tightly cover the surface of the hand hole, the inclination angle of the circular cover plate is required to be basically consistent with that of the hand hole.

In order to achieve the above-mentioned desired effect, the socket can take any one of the following three forms:

1) the lower section of the dropping liquid pipe is provided with a circumferential sleeve groove, and the sleeve groove is sleeved with a central hole of a circular cover plate. The external diameter of the sleeve groove is smaller than the external diameter of the dropping liquid pipe of the adjacent part, so that the circular cover plate can not slide up and down on the pipe body of the dropping liquid pipe. Meanwhile, a certain gap is reserved between the sleeving groove and the central hole of the circular cover plate, so that the circular cover plate can swing at a certain angle and can cover the surface of the hand hole basically. But because can swing, the dropwise add cup body is too unstable, does not easily lead to excessive slope when not having artifical support for the reagent spills out.

2) The lower section of the dropping pipe and the circular cover plate are welded to form a certain fixed angle (90-theta) between 45 and 75 degrees, when the circular cover plate is tightly covered on the surface of the hand hole, the dropping pipe is at the vertical position at the specific angle, and can only be at the position close to the plumb line at other angles. After the dripping cup is welded and fixed, the dripping cup cannot be vertical when being inserted into hand holes with other inclination angles, the body of the dripping cup cannot be kept horizontal, a reagent cannot be added too much at one time, and the interchangeability of the dripping cup and the hand holes is poor.

3) The lower section of the dropping liquid pipe is connected with the circular cover plate by adopting a horn-mouth-shaped corrugated pipe (the corrugated pipe with gradually changed diameters is a corrugated pipe with the section integrally in a shape similar to a terrace, and the connection part is provided with a flange in a proper shape for convenient connection), and the caliber d of the small end of the horn mouth can be matched and connected with the outer diameter of the dropping liquid pipe and is connected on the outer wall of the dropping liquid pipe; the caliber D of the large end of the bell mouth is slightly larger than the aperture of the central hole of the circular cover plate, and is connected to the periphery of the central hole of the upper surface of the circular cover plate. The preferred 2 times ~ 3 times of root No. of root of the pipe wall external diameter of dropping liquid pipe in the aperture of circular apron central hole (this external diameter dimension guarantees circular apron, the bellows homoenergetic is connected with the dropping liquid pipe, the hand hole has suitable cooperation, inclination is too big, both ends external diameter dimension differs greatly, unsuitable following stainless steel), when the dropping liquid pipe hypomere inserted the hand hole that the angle of inclination is arbitrary angle, through the tensile or compression state of adjusting a certain one side of horn mouth form bellows (the bellows shrink that dropping liquid pipe the central axis is acute angle one side with the hand hole plane, dropping liquid pipe the central axis is the bellows tensile of obtuse angle one side with the hand hole plane), when the homoenergetic makes the dropping liquid pipe plumb set up, circular apron closely laminates on the hand hole surface of slope simultaneously basically.

The bell-mouth-shaped corrugated pipe is preferably made of 0.2-0.6mm stainless steel, has corrosion resistance, good rigidity and proper bending deformability, and can well keep a required shape during stretching and compression, namely, the dropping liquid pipe can be adjusted to and keep a plumb state no matter the value of theta; and even when not manually supporting, the body of the dripping cup can be filled with the reagent, and the reagent is not splashed out due to instability in the dripping process.

In the three forms, when the dripping cup is inserted into a hand hole of a container such as a liquid preparation tank and the like for dripping the reagent, the liquid in the container is not easy to splash, and the outside dust is not easy to drop into the container.

Has the advantages that:

the utility model discloses can be applicable to and add various liquid reagent to jar in or other containers, the dropping liquid pipe lower extreme of dropwise add cup inserts fast conveniently, can insert the hand hole perpendicularly or slightly aslope, has better maneuverability in narrow and small space. And the circular cover plate can tightly cover the hand hole, so that the reagent in the container can not splash, dust or liquid outside the container can not mistakenly fall into the tank during dripping, and the operation environment of a workshop and the purity of the reagent in the container are ensured.

And the use of the ball valve is convenient for manually controlling the speed and the addition amount of the dropwise adding reagent, ensures that the reagent in the tank is uniformly mixed or is subjected to chemical reaction at a uniform speed, and ensures that the reaction product has reliable quality or the reagent has good purity.
