DETAILED DESCRIPTION

[0018] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] Reference Figure 1As shown, the embodiment of the present application discloses a mixer for temporary plugging agent production, comprising: a stirring kettle body 1, a stirring shaft 2 and a stirring paddle 3, the stirring shaft 2 is rotatably arranged in the stirring kettle body 1, and a plurality of stirring paddles 3 are installed on the stirring shaft 2; a feeding mechanism, used for conveying polymer raw materials; a cloth component 4, arranged on the stirring shaft 2, between the stirring paddle 3 and the feeding mechanism, for receiving and buffering the polymer raw materials; a blanking gap 41, arranged between the outer edge of the cloth component 4 and the inner wall surface of the stirring kettle body 1; a driving motor 5, used for driving the stirring shaft 2 to rotate, can drive the cloth component 4 to rotate, so as to convey the polymer raw materials toward the blanking gap 41; can also drive the stirring paddle 3 to rotate, so as to perform a stirring operation.

[0020] During specific use, the polymer raw material is automatically output through the feeder structure, and at the same time, the driving motor 5 continuously drives the stirring shaft 2 to rotate; during the rotation of the stirring shaft 2, the output polymer raw material falls onto the cloth component 4 along the circumferential direction; the stirring shaft 2 continues to rotate, and under the action of the inertia of the polymer raw material itself, the polymer raw material moves toward the blanking gap 41 and falls under the cloth component 4; of course, a temporary plugging agent is fed under the cloth component 4, and during the rotation of the stirring shaft 2, the stirring paddle 3 can continuously stir the temporary plugging agent and the polymer raw material.

[0021] Of course, the mixer is also equipped with a pipe for conveying a temporary plugging agent into the stirring tank body 1 .

[0022] It can be understood that a bracket is provided in the stirring tank body 1, and the stirring shaft 2 is rotatably provided on the bracket through a bearing.

[0023] By using the utility model, the polymer raw material can be thinned along the radial direction of the fabric component 4, the thickness of the polymer raw material can be reduced, and it can be continuously put into the temporary plugging agent along the circumferential direction; by using the utility model, the polymer raw material can be slowly put into the temporary plugging agent, the occurrence of the polymer raw material clumping in the temporary plugging agent can be effectively reduced, and the mixing efficiency of the temporary plugging agent production can be effectively improved.

[0024] It is worth mentioning that the rotation speed of the cloth component 4 can be controlled by changing the rotation speed of the stirring shaft 2, so as to change the feeding rate of the polymer raw material.

[0025] Furthermore, the mixer also includes: a hopper 6 installed between the feeding mechanism and the cloth component 4, with one end facing the feeding mechanism and the other end facing the cloth component 4, for receiving the polymer raw material and conveying it toward the cloth component 4.

[0026] Specifically, the feeding mechanism includes: a conveying auger 9 and a storage component 10, which is used to store polymer raw materials and is arranged above the feed port of the conveying auger 9. The discharge port of the conveying auger 9 is above the cloth component 4. It can be understood that the polymer raw materials can be continuously pushed to the hopper 6 by driving the auger built into the conveying auger 9 by a motor, without manual feeding, thereby reducing the amount of manual labor.

[0027] Reference Figure 2 As shown, the mixer also includes: a functional ring 7, which is arranged on the inner wall surface of the stirring tank body 1, and a functional channel 72 for the polymer raw material to pass through is formed between the functional ring 7 and the cloth component 4; a plurality of protrusions 71, which are arranged on the functional ring 7 and the cloth component 4 and are located in the functional channel 72.

[0028] Of course, the protrusions 71 on the functional ring 7 and the protrusions 71 on the fabric part 4 are arranged alternately. In the process of the polymer raw material passing through the functional channel 72, the staggered protrusions 71 can squeeze the damp and clumped polymer raw material, preliminarily break up the damp and clumped polymer raw material, and improve the stirring efficiency of the subsequent stirring paddle 3.

[0029] Specifically, the mixer also includes: a first inclined plane and a second inclined plane arranged in parallel, the first inclined plane is arranged on the functional ring 7, the second inclined plane is arranged on the fabric component 4, and the protrusions 71 are both arranged on the first inclined plane and the second inclined plane; the first inclined plane and the second inclined plane are arranged at a fixed angle inclined to the horizontal plane, extending the length of the functional channel 72 and increasing the time for the polymer raw material to pass through the functional channel 72.

[0030] Specifically, the protrusion 71 is hemispherical, which prevents the polymer raw material from being retained on the protrusion 71 .

[0031] Specifically, the mixer also includes a scraping component 8, which is in sliding contact with the inner wall surface of the stirring tank body 1 and is arranged on the stirring paddle 3. During the rotation of the stirring paddle 3, the scraping component 8 can also scrape off the polymer raw material retained on the inner wall surface of the stirring tank body 1 to ensure the production quality of the temporary plugging agent mixing.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention. Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the equivalent technology of the claims of the present invention, the present invention is also intended to include these modifications and variations.
