Abstract

This utility model discloses a mud cake mixing device for sand washing tailwater treatment, including a machine body. The feed hopper has fixed frames on both inner walls, and a first servo motor is installed inside each fixed frame. One end of the output shaft of the first servo motor is connected to a bidirectional screw via a coupling, and a first synchronous pulley is fitted onto one end of the bidirectional screw. Under the action of the first servo motor, the rollers of this mud cake mixing device form a bidirectional limiting sliding structure with the fixed frame through the bidirectional screw, slide bar, and movable block. This allows for the preliminary crushing of the mud cake generated from tailwater treatment through the relatively moving rollers, facilitating feeding and increasing the mixing efficiency with other materials. The baffle of this device, under the action of a second servo motor, forms a rotating structure within the feed hopper via a first rotating shaft. This ensures that the mud cake is initially crushed while facilitating subsequent mixing.

Description

Technical Field

[0001] This utility model relates to the field of sand washing tailwater treatment technology, specifically to a mud cake mixing device for sand washing tailwater treatment. Background Technology

[0002] Washing tailwater mainly originates from the wastewater generated during the sand washing process in sand and gravel production enterprises. This wastewater typically contains large amounts of silt, suspended solids, organic matter, and inorganic salts, and has high chemical oxygen demand (COD) and suspended solids content. During tailwater treatment, to improve the physical properties of the sludge cake and enhance its utilization value, mixing equipment is used to mix it with other substances.

[0003] In operation, mixing equipment uses a motor assembly to drive mixing blades to rotate, thereby agitating and mixing the mud cake and other materials. However, existing mixing equipment is inconvenient for feeding mud cakes after wastewater treatment, and direct feeding of mud cakes can reduce subsequent mixing efficiency. Therefore, a mud cake mixing device for sand washing wastewater treatment is proposed to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mud cake mixing device for sand washing tailwater treatment, comprising a machine body, a feeding hopper at the upper end of the machine body, a feeding pipe above the feeding hopper, fixed frames on both inner walls of the feeding hopper, a first servo motor inside the fixed frames, one end of the output shaft of the first servo motor being connected to a bidirectional screw via a coupling, a first synchronous pulley being fitted at one end of the bidirectional screw, a second synchronous pulley being correspondingly provided on one side of the first synchronous pulley, and a synchronous belt being fitted on the outer walls of the first and second synchronous pulleys, a bidirectional screw also being inserted inside the second synchronous pulley, and a sliding rod being correspondingly provided below the bidirectional screw, movable blocks being inserted at both ends of the bidirectional screw and the sliding rod, and connecting blocks being provided on opposite sides of the movable blocks, with rollers inserted between the connecting blocks;

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The roller of the mud cake mixing device for sand washing tailwater treatment forms a bidirectional limiting sliding structure with the fixed frame through a bidirectional screw, slide bar, movable block and a first servo motor.

Detailed Implementation

[0017] 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.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a mud cake mixing device for sand washing tailwater treatment, including a machine body 1, a feeding hopper 2 at the upper end of the machine body 1, and a feeding pipe 3 above the feeding hopper 2. Fixing frames 4 are respectively provided on the inner walls of both sides of the feeding hopper 2, and a first servo motor 5 is provided inside the fixing frames 4. One end of the output shaft of the first servo motor 5 is connected to a bidirectional screw 6 via a coupling, and a first synchronous pulley is sleeved on one end of the bidirectional screw 6. A second synchronous pulley is correspondingly provided on one side of the first synchronous pulley, and a synchronous belt 9 is sleeved on the outer wall of the first and second synchronous pulleys. A bidirectional screw 6 is also inserted inside the second synchronous pulley, and a sliding rod 7 is correspondingly provided below the bidirectional screw 6. Movable blocks 8 are respectively inserted at both ends of the bidirectional screw 6 and the sliding rod 7, and connecting blocks are respectively provided on opposite sides of the movable blocks 8. A roller shaft 10 is inserted between the connecting blocks. It should be noted that the movable blocks 8 are provided with spiral holes and through holes to ensure that the movable blocks 8 can slide in a limited manner.

[0019] Furthermore, under the action of the first servo motor 5, the roller 10 forms a bidirectional limiting sliding structure with the fixed frame 4 through the bidirectional screw 6, slide bar 7, movable block 8, and fixed frame 4. Thus, the roller 10, which moves relatively, can initially squeeze and crush the mud cake generated by the tailwater treatment, so that it can be dispersed and fed in the subsequent process.

[0020] The fixed frame 4 has a fixed box at each end below, and a second servo motor 11 is provided inside the fixed box. One end of the output shaft of the second servo motor 11 is connected to the first rotating shaft 12 through a coupling, and the first rotating shaft 12 has a baffle 13 on its outer wall.

[0021] Furthermore, under the action of the second servo motor 11, the baffle 13 forms a rotating structure in the feed hopper 2 through the first rotating shaft 12, thereby ensuring that the mud cake can be initially crushed in the feed hopper 2 while ensuring that the mud cake can be properly mixed in the subsequent process.

[0022] Below the baffle 13, a connecting frame is provided on the machine body 1. Multiple feed ports 19 are evenly opened on the four sides of the connecting frame on the upper surface of the machine body 1. A motor 14 is provided inside the connecting frame. One end of the output shaft of the motor 14 is connected to a second rotating shaft 15 through a coupling. A mixing blade 16 is provided on the outer wall of the second rotating shaft 15. An ultraviolet lamp 17 is provided at the upper part of the machine body 1. A spray arm is embedded in one side of the machine body 1. A nozzle 18 is provided below the spray arm. It should be noted that multiple sets of electrical equipment in this device are connected to the power supply equipment through power lines. The working status of the electrical equipment is monitored by sensors, controllers and other equipment to ensure that the electrical equipment in this device can perform normal control work.

[0023] Furthermore, the upper end face of the connecting frame on the motor 14 is an arc structure, and the mixing blades 16 form a rotating structure in the machine body 1 through the second rotating shaft 15 under the action of the motor 14. Thus, the arc structure connecting frame ensures that the mud cake after initial crushing can be dispersed and fed, thereby increasing the mixing efficiency after the mud cake is fed.

[0024] Working Principle: In the sand washing tailwater treatment mud cake mixing equipment, the mud cake generated from the tailwater treatment is first fed into the feed hopper 2 through the feed pipe 3. Then, the first servo motor 5 is started. One end of the output shaft of the first servo motor 5 drives a bidirectional screw 6 to rotate via a coupling. The bidirectional screw 6, in turn, drives another set of bidirectional screws 6 to rotate synchronously via a first synchronous pulley, a second synchronous pulley, and a synchronous belt 9. This causes the sliding block 8 to slide relative to the sliding rod 7, thereby causing the roller shaft 10 to move relative to the sliding block 8. This relative movement of the roller shaft 10 initially crushes the mud cake, facilitating subsequent dispersion feeding. After the initial crushing of the mud cake is completed, the second servo motor 11 is started. The output shaft of the second servo motor 11 drives a first rotating shaft 12 to rotate via a coupling, allowing the first servo motor 11 to move relative to the sliding block 7. A rotating shaft 12 drives a baffle 13 to rotate, allowing the crushed mud cake to directly enter the machine body 1 for mixing. Simultaneously, the mud cake is dispersed and fed through multiple feed ports 19 under the action of the arc-shaped connecting frame, thereby increasing the mixing efficiency of the mud cake inside the machine body 1. After the mud cake is fed, the motor 14 can be started. One end of the output shaft of the motor 14 drives the second rotating shaft 15 to rotate through a coupling, thereby stirring and mixing the mud cake and other materials through the rotating mixing blades 16. At the same time, the mixing process inside the machine body 1 can be sterilized by ultraviolet lamp 17, and when the moisture content of the mud cake is low, water is added to the inside of the machine body 1 through the nozzle 18 to further ensure the mixing effect of the device on the mud cake. This is the operation process of the mud cake mixing equipment for sand washing tailwater treatment.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
