[0003] The thickener with a sealing mechanism described in application number CN202411727003.5 has no feeding auxiliary structure. In actual use, because the liquid medicine and the material to be processed are placed directly and simultaneously, it is difficult to fully mix the liquid medicine during slow stirring, resulting in uneven mixing of the liquid medicine in different areas and incomplete separation. Utility Model Content

[0004] The purpose of this invention is to provide an optimized feeding well structure for online self-dilution control of a thickener, in order to solve the problem mentioned in the background art where the existing feeding auxiliary structure on the market, in actual use, directly places the liquid medicine and the processed material simultaneously, and it is difficult to fully mix the liquid medicine during slow stirring, resulting in uneven mixing of the liquid medicine in different areas and incomplete separation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an optimized structure for the feed well of a thickener with online self-dilution rate control, comprising a first feed hopper, a second feed hopper, an eccentric disc, a motor, and a guide groove;

[0006] The first feed hopper is provided with a screening structure inside. The screening mechanism includes a motor, an eccentric disk and a second feed hopper. The second feed hopper uses the eccentric disk to achieve the shaking, mixing and separation functions.

[0007] The bottom of the second feed hopper is provided with a swing mechanism, which includes a direct injection nozzle, a swing rod, a traction rod, a reversing ring, and a guide groove. The swing rod uses the power of the second feed hopper swinging to swing left and right to pull the reversing ring and the direct injection nozzle to perform a mixed function of reciprocating swing.

[0009] Using the above technical solution, the first feed hopper has an overall gyroscope-shaped structure, and the surface of the cone-shaped part at the bottom of the first feed hopper is evenly perforated. The gyroscope-shaped structure design helps the material to slide naturally and concentrate under the action of gravity, and the holes in the cone-shaped part at the bottom can perform preliminary screening of the material, separating fine particles in advance and improving the efficiency of subsequent processing.

[0010] As a preferred technical solution of this utility model, a motor is fixedly connected to the upper surface of the first feed hopper, and the bottom output shaft of the motor is fixedly connected to the eccentric disk.

[0011] Using the above technical solution, the output shaft at the bottom of the motor is fixedly connected to the eccentric disc. The motor drives the eccentric disc to rotate, providing stable power for the shaking of the second feed hopper, ensuring the continuity and stability of the screening and mixing effect.

[0012] As a preferred technical solution of this utility model, four eccentric disks are arranged below the U-shaped support of the first feed hopper, and the second feed hopper is rotatably connected below the eccentric disks.

[0017] Using the above technical solution, a second feed hopper is slidably connected above the rocker arm, and a round rod is vertically fixed above the left side of the rocker arm. Traction rods are mounted on both sides above the round rod of the rocker arm. When the second feed hopper swings, it drives the rocker arm, which in turn transmits power through the traction rods.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. It achieves precise online control of self-dilution amount. Through the reciprocating oscillation of the direct injection nozzle and the control of the injection volume, the dilution degree can be adjusted in a timely manner according to the actual situation of the material, ensuring the stability of the material concentration in the thickener and improving the subsequent treatment effect.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1 - Figure 4 The present invention provides a new type of technical solution: an optimized structure for the feed well of a thickener with online self-dilution control, comprising a first feed hopper 1, a second feed hopper 2, an eccentric disc 3, a motor 4, a direct injection nozzle 5, a rocker arm 6, a traction rod 7, a reversing ring 8, and a guide groove 9.

[0031] The first feed hopper 1 is gyroscope-shaped with uniformly spaced holes in its conical lower section for preliminary material screening. Its inner side houses a screening structure consisting of a motor 4, an eccentric disc 3, and a second feed hopper 2. Four U-shaped supports are located on the upper surface of the first feed hopper 1, with the motor 4 fixed above them. The output shaft of the motor 4 is connected to the eccentric disc 3. The four eccentric discs 3 are distributed below the U-shaped supports, causing the cylindrical second feed hopper 2, which has holes on its surface, to shake, thus achieving material screening and mixing.

[0032] The swing mechanism at the bottom of the second feed hopper 2 includes a direct injection nozzle 5, a swing rod 6, a traction rod 7, a reversing ring 8, and a guide groove 9. One end of the swing rod 6 is rotatably connected to the inner wall of the first feed hopper 1, forming a guide rail structure. The middle part is a circular ring structure, and the upper part is slidably connected to the second feed hopper 2. When the second feed hopper 2 swings, it drives the swing rod 6, which in turn pulls the reversing ring 8 through the traction rod 7. The reversing ring 8 slides in the guide groove 9, thereby causing the direct injection nozzle 5 to swing back and forth. The direct injection nozzle 5 can spray diluent onto the material to achieve self-dilution.

[0033] Working principle: When using an optimized feeding well structure with online self-dilution control for a thickener, the equipment is installed in a suitable position on the thickener, various pipelines are connected, and the motor 4 is started. The motor 4 drives the eccentric disk 3 to rotate. The rotation of the eccentric disk 3 causes the second feed hopper 2 to shake. The material is shaken, mixed, and separated in the second feed hopper 2. The holes in the conical part below the first feed hopper 1 perform preliminary screening of the material. Fine particles fall through the holes. As the second feed hopper 2 shakes, it drives the rocking rod 6 to swing left and right. The rocking rod 6 drives the reversing ring 8 to slide in the guide groove 9 through the traction rod 7, thereby causing the direct injection nozzle 5 to swing back and forth on the inner wall of the first feed hopper 1. During the swinging process of the direct injection nozzle 5, diluent is sprayed onto the material according to the set dilution amount, realizing online control of the self-dilution amount, while fully mixing the material to complete the feeding.

[0034] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
