Description

Technical Field

[0001] The utility model relates to the technical field of defoaming agents, and more specifically, to a defoaming performance testing device for defoaming agents. Background Art

[0002] In industries such as dyeing, papermaking, fermentation, sugar making, and petroleum distillation, foam sometimes forms on the liquid surface, which is extremely detrimental to the production process. The control of foam by defoamers is reflected in two aspects: defoaming and foam suppression. To screen or prepare a suitable defoamer, it is usually necessary to test the performance of the defoamer. Currently, most mainstream methods are manually shaken, which cannot produce foam at the same time and with the same force, resulting in errors in the control experiment of multiple defoamers. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a defoaming performance testing device for a defoaming agent, which has the advantages of comparing multiple control experiments at the same time and having a small error.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a defoaming performance testing device for a defoaming agent, comprising a base, a box body fixedly installed on the top of the base, a rotating shaft rotatably installed in the middle of the box body, a half gear fixedly installed at the rear end of the rotating shaft, a metal shell is provided on the outer side of the half gear, a fixed platform is fixedly installed on the left and right sides of the metal shell, a liquid feed bracket is fixedly installed in the middle of the fixed platform, and a pipe clamp is movably installed in the middle of the liquid feed bracket.

[0005] As a preferred technical solution of the utility model, a lead screw is rotatably installed at the bottom of the fixed platform, a column is fixedly installed in the middle of the lead screw, a trapezoidal column is fixedly installed on the side of the column, a spring is fixedly installed on the left side of the trapezoidal column, a steel ball is fixedly installed on the left end of the spring, and a feedback plate is fixedly installed on the top of the base.

[0006] As a preferred technical solution of the utility model, teeth are provided on the inner side of the metal shell and mesh with the half gear.

[0007] As a preferred technical solution of the utility model, the lead screw passes through the bottom of the fixed platform, is inserted into the base, and meshes with the contact surface of the base.

[0008] As a preferred technical solution of the utility model, the steel ball contacts the feedback plate when rotating around the lead screw.

[0009] As a preferred technical solution of the utility model, a servo motor is provided at the front end of the rotating shaft.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The utility model sets a rotating shaft, and drives the half gear to rotate through the actuation of the servo motor. The half gear can realize the periodic up and down movement of the metal shell through the meshing of the inner teeth of the metal shell, and drive the movement of the fixed platforms on the left and right sides. The slurry is placed on the top of the slurry support and fixed by the sliding of the pipe clamp. The slurry support is driven to move periodically through the fixed platform, and the performance of the defoaming agent can be tested by comparing multiple control experiments with the same force at the same time.

[0012] 2. The utility model provides a lead screw which passes through the bottom of the fixed platform and is inserted into the base, and meshes with the contact surface of the base, so that when the lead screw is rotated, the fixed platform drives the metal shell to move upward, thereby reducing the contact between the inner teeth of the metal shell and the half gear, and controlling the movement amplitude of the liquid material support on the side of the fixed platform. A spring is installed on the left side of the trapezoidal column, and a steel ball is installed on the left end of the spring, so that when the column drives the steel ball to rotate around the lead screw through a fixed angle, it collides with the feedback plate to send out feedback, thereby achieving precise control of the height of the fixed platform and thus controlling the movement amplitude of the liquid material support.

The slurry is placed on the top of the slurry support 7 and fixed by the sliding of the pipe clamp 15. The slurry support 7 is driven to move periodically by the fixed platform 6, so as to realize the performance of the defoaming agent by comparing and testing multiple control experiments with the same force at the same time.

[0025] By providing teeth on the inner side of the metal shell 5 and meshing with the half gear 4 , the metal shell 5 can be driven to move periodically by rotating the half gear 4 .

[0026] The lead screw 8 penetrates the bottom of the fixed platform 6 and is inserted into the base 1, and meshes with the contact surface of the base 1;

[0032] The working principle and use process of the utility model are as follows: when preparing for the test, the liquid test tube is placed on the liquid support 7 and clamped by the sliding tube clamp 15. By setting a lead screw 8, the lead screw 8 passes through the bottom of the fixed platform 6 and is inserted into the base 1, and meshes with the contact surface of the base 1, it can be achieved that when the lead screw 8 is rotated, the fixed platform 6 drives the metal shell 5 to move upward, thereby reducing the contact between the inner teeth of the metal shell 5 and the half gear 4, and the movement amplitude of the liquid support 7 on the side of the fixed platform 6 can be controlled. By setting a trapezoidal column 10 with a spring 11 installed on the left side, and a steel ball 12 is installed on the left end of the spring 11, it can be achieved that when the column 9 drives the steel ball 12 to rotate around the lead screw 8 through a fixed angle, it collides with the feedback plate 13 to send feedback, thereby achieving precise control of the height of the fixed platform 6 and thus controlling the movement amplitude of the liquid support 7, and rotating the lead screw 8 by a certain angle to make the bottom of the fixed platform 6 horizontal.

[0033] At the beginning of the test, the servo motor 14 is turned on to drive the rotating shaft 3, driving the half gear 4 to rotate. The half gear 4 can realize the periodic up and down movement of the metal shell 5 through the meshing of the inner teeth of the metal shell 5, driving the movement of the left and right fixed platforms 6, and the slurry is placed on the top of the slurry support 7 and fixed by the sliding of the tube clamp 15.
