Description

Technical Field

[0001] The utility model relates to the field of liquid slurry silos, in particular to a bubble removal silo device. Background Art

[0002] In daily production, bubbles are a common problem, especially in the production process under liquid environment. It is inevitable that bubbles will be generated during the mutual reaction, mixing and transportation of materials. The appearance of bubbles in some chemical processes is beneficial to production, while most bubbles will have an adverse effect on the production process. Enterprises will take necessary measures to eliminate bubbles, but chemical processes are often continuous production processes. It is difficult to manually clean bubbles when the equipment is in a closed state. The commonly used solution is to use defoaming agents to defoam, and mechanical defoaming is rarely used. However, for compact chemical processes, the appearance of defoaming agents will introduce new species into the system, which will affect the application of products in downstream industries. If bubbles can be removed mechanically, the use of defoaming agents can be avoided. For liquid slurry systems, dispersing materials by bubbling is a common method. For liquid systems with low viscosity, although the bubbling dispersion effect is more effective than stirring, bubbling itself will produce a large number of bubbles. In addition, if the material has a foaming property, bubbles will continue to accumulate in the silo. If the bubbles are not eliminated in time, the volume of the silo will be occupied by bubbles, and the silo air pressure will change, which will seriously affect the production process and even bring safety hazards.

[0003] Therefore, how to develop a bubble removal silo device to effectively reduce the bubbles in the material has become a technical problem that needs to be solved urgently by technical personnel in this field. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

Specifically, the feed port 1 and the discharge port 10 are both connected to external equipment through pipelines, and the pipelines are both provided with solenoid valves, and the design of the solenoid valves can realize the control of opening and closing the flow of materials.

[0028] Specifically, the chamber of the silo 5 is divided into a cylindrical section at the top and a conical section at the bottom. The top of the cylindrical section is connected to an air suction assembly, and a feed port 1 is provided on the side wall of the conical section.

[0029] Specifically, the air suction assembly includes an air suction hood 8 and an air duct 9. The air suction hood 8 is positioned and connected to the top plate of the cylindrical section of the silo 5. The air suction hood 8 is connected to an external air suction recovery system through the air duct 9. The air suction recovery system can be connected to the bubbler as an air supply end, and the air bubbles generated in the silo can be recycled after being uniformly recovered by the air suction recovery system, thereby avoiding pollution caused by the air bubbles being discharged.

[0030] Specifically, the light mesh screen 6 is positioned on the side wall of the silo 5 by the inner magnet 2 and the outer magnet 4, the outer magnet 4 is connected to the lifting system 3, and the lifting system 3 drives the outer magnet 4 to move up and down. The bottom end of the lifting system 3 is connected to the outer side wall of the silo 5, and the telescopic end of the lifting system 3 is positioned and connected with the outer magnet 4. Specifically, the lifting system 3 is symmetrically provided with two, or a plurality of lifting systems are evenly distributed around the circumference to ensure the smooth movement of the light mesh screen 6.

[0031] In one embodiment, the lifting system 3 uses a linear motor, which is positioned and connected to the side wall of the silo 5, and the telescopic rod of the linear motor is vertically upward and the top end is positioned and connected to the external magnet 4. Specifically, the external magnet 4 is bonded or fastened to the top end of the telescopic rod by bolts.

[0032] In another embodiment, if Figure 2As shown, the lifting system 3 adopts a forward and reverse motor 302, a gear 303 and a rack 304. The forward and reverse motor 302 is installed on the side wall of the silo 5 through a positioning frame 301. The rotating shaft of the forward and reverse motor 302 meshes with the rack 304 through the gear 303 and drives the rack 304 to move up and down. The external magnet 4 is positioned and connected to the top of the rack 304 by bonding or bolts, and one side wall of the external magnet 4 is in contact with the side wall of the silo 5; a positioning through hole is provided on the positioning frame 301 to cooperate with the rack 304, and a limiting member is connected to the non-working side of the rack 304.

[0033] During operation, the forward and reverse motor is started, and when it rotates clockwise or counterclockwise, it drives the gear 303 to rotate, thereby driving the rack 304 and the external magnet 4 to move straight up along the positioning through hole; when it rotates counterclockwise or clockwise, it drives the gear 303 to rotate, thereby driving the rack 304 and the external magnet 4 to move straight down along the positioning through hole, and during the movement, the lightweight mesh screen 6 in the silo is simultaneously driven to move up and down to achieve the removal of bubbles in the material.

[0034] Specifically, the bubbler 7 includes a bubble panel and a vent pipe. The bubble panel is located on the bottom plate inside the silo 5. The bubble panel is connected to an external air supply end through the vent pipe.

[0036] The use process of the utility model is as follows:

[0037] First, the material enters the silo 5 through the feed port 1. Two lifting systems 3 are connected in parallel at both ends of the outer side of the silo. An external magnet 4 is fixedly connected to the upper end of the lifting system. A lightweight mesh screen 6 that can move up and down is provided inside the silo. The surface of the lightweight mesh screen is covered with micropores, and two inner magnets 2 are fixed at both ends. The two inner magnets correspond to the two outer magnets one by one and are adsorbed and connected together. When the outer magnet moves up and down driven by the lifting system, the lightweight mesh screen is synchronously driven to move up and down due to the attraction of the magnets. A bubbler 7 is provided at the bottom of the silo for material dispersion, and a discharge port 10 at the bottom of the silo is used for material removal. The suction hood 8, the air duct 9 and the suction recovery system at the top of the silo are used for gas recovery after the bubbles are eliminated.

[0038] When the material enters the silo and generates bubbles, the bubbles float to the liquid surface, and the light mesh screen 6 moves upward from below the liquid surface due to the drive of the external magnet 4. When the light mesh screen passes the liquid surface, the bubbles are trapped on the light mesh screen plate because the micropores can filter the liquid and move upward to the bottom of the suction hood. The suction hood connected to the induced draft pipe sucks the bubbles on the plate surface into the suction recovery system under the action of wind.

[0039] When the bubbles on the plate surface of the light mesh screen 6 are removed, it descends again into the lower end of the liquid surface, and the above process is repeated repeatedly, which can meet the operation of continuous bubble removal in the production process.

[0040] In the embodiment of the utility model, the lightweight mesh screen cooperates with the lifting system to form a mechanical defoaming structure. No new material such as defoaming agent is introduced during the defoaming process, which effectively ensures the cleanliness of the material and makes the defoaming effect more thorough.
