Description

Technical Field

[0001] The utility model belongs to the technical field of experimental dilution devices, in particular to a dilution device for the production of polyacrylamide emulsion. Background Art

[0002] Patent application number 202121323435.1 discloses a dilution device for polyacrylamide emulsion experiments, including a main body, a bracket, a box cover and a mesh plate, etc. The motor drives the rotating shaft to rotate, and the rotating shaft drives the stirring rod and the frame to stir quickly. The mesh plate inside the frame decomposes the polyacrylamide emulsion and dilutes it with water.

[0003] However, the density of high-concentration polyacrylamide emulsion is different from that of water. When the two are not stirred in the main body, they are easy to form upper and lower layers. In the above technical solution, the two liquids can only be diluted by horizontal stirring, which is not convenient for the two layered liquids to be quickly mixed up and down, resulting in a longer mixing time to complete the dilution, reducing the dilution efficiency.

[0004] Based on this, it is necessary to make partial improvements to the structure of agitating the polyacrylamide emulsion and water in the above disclosed technical solution. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a dilution device for the production of polyacrylamide emulsion. After the liquid is stirred, it will contact and mix with another liquid upward or downward according to the inclination direction of the connecting pipe, thereby avoiding the phenomenon that the liquid can only be diluted by horizontal stirring, and the two liquids in the upper and lower layers are quickly contacted and mixed, which reduces the mixing time required for dilution and improves the dilution efficiency.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A dilution device for producing polyacrylamide emulsion comprises a main body, a box cover is installed on the top of the main body, a motor is installed on the top of the box cover, a rotating shaft is installed on the output end of the motor, stirring rods are welded on both sides of the rotating shaft, a frame is welded on the end of the stirring rod away from the rotating shaft, a mesh plate is welded inside the frame, a plurality of mesh holes are provided on the mesh plate, the frame on the left side is higher than the frame on the right side, a screw is threadedly connected to the top of the frame, the bottom end of the screw extends into the frame and is rotatably connected to an adjustment plate, the adjustment plate is provided with through holes having the same number as the plurality of mesh holes, a rubber sleeve located at each mesh hole is fixedly connected to the side of the mesh plate, a connecting pipe is fixedly connected to the end of the rubber sleeve away from the mesh plate, the mesh hole is connected to the connecting pipe through the rubber sleeve, and each of the connecting pipes passes through a corresponding through hole.

[0008] Furthermore, a baffle is fixedly sleeved on the outer side of the end portion of the connecting pipe.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. By rotating the screw to drive the adjusting plate, the connecting pipe can be tilted upward or downward with the adjusting plate in conjunction with the rubber sleeve. After the liquid is stirred and passes through the mesh, it will contact and mix with another liquid upward or downward in the direction of the tilt of the connecting pipe, avoiding the phenomenon that the liquid can only be diluted by lateral stirring, so that the two layered liquids can quickly contact and mix up and down, reducing the mixing time required for dilution and improving the dilution efficiency.

[0011] 2. The baffle plate prevents the inclined connecting pipe from falling out of the through hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention. Example

[0018] See attached Figure 1-3As shown, a dilution device for producing polyacrylamide emulsion comprises a main body 1, a box cover 2 is installed on the top of the main body 1, a motor 3 is installed on the top of the box cover 2, a rotating shaft 4 is installed on the output end of the motor 3, stirring rods 5 are welded on both sides of the rotating shaft 4, a frame 6 is welded on the end of the stirring rod 5 away from the rotating shaft 4, a mesh plate 7 is welded in the frame 6, a plurality of mesh holes 8 are opened on the mesh plate 7, the left frame 6 is higher than the right frame 6, a screw rod 9 is threadedly connected to the top of the frame 6, the bottom end of the screw rod 9 extends into the frame 6 and is rotatably connected to an adjusting plate 10, the adjusting plate 10 is provided with through holes 11 having the same number as the plurality of mesh holes 8, a rubber sleeve 12 located at each mesh hole 8 is fixedly connected to the side of the mesh plate 7, a connecting pipe 13 is fixedly connected to the end of the rubber sleeve 12 away from the mesh plate 7, the mesh hole 8 is connected to the connecting pipe 13 through the rubber sleeve 12, and each connecting pipe 13 passes through the corresponding through hole 11.

[0019] A baffle 14 is fixedly sleeved on the outer side of the end of the connecting pipe 13 .

[0020] Working principle: It should be noted that, in the present utility model, only partial improvements are made to the disclosed patent structure, and the structures not mentioned, such as the additive box and the gear lever, are not changed, and their original functions and effects are retained. The connecting tube 13 in the higher frame 6 is tilted downward in advance. Specifically, the screw 9 on the frame 6 is screwed, and the screw 9 drives the adjustment plate 10 to move downward, and then the upper part of the inner wall of all the through holes 11 on the adjustment plate 10 presses down each connecting tube 13, and the lower part of the rubber sleeve 12 at the connecting tube 13 is slightly deformed, so that the connecting tube 13 is tilted downward as a whole. Similarly, the connecting tube 13 in the lower frame 6 is tilted upward, and the high-concentration polyacrylamide The density of amine emulsion is greater than that of water. Therefore, when not stirred, water tends to be located above the polyacrylamide emulsion. When diluting, the motor 3 is started to drive the shaft 4 to rotate, and the shaft 4 drives the stirring rod 5 to rotate. While the stirring rod 5 stirs the two liquids, it drives the two frames 6 and the mesh plates 7 inside to rotate. When the upper liquid passes through the mesh plate 7 at the higher frame 6, the liquid passes through the rubber sleeve 12 from each mesh 8 and is finally discharged downward from the downwardly inclined connecting pipe 13. Similarly, when the lower liquid passes through the mesh plate 7 at the lower frame 6, it is discharged upward from the upwardly inclined connecting pipe 13, so that the two liquids in the upper and lower layers are quickly contacted and mixed. This process continues until the dilution is completed.

For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model; therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
