Description

Technical Field

[0001] The utility model belongs to the technical field of sponge processing equipment and relates to a calcium carbonate pre-stirring and discharging device. Background Art

[0002] As a hard sponge additive, calcium carbonate solution is prone to precipitation during continuous addition. Therefore, it is generally necessary to perform pre-stirring before addition, and further stirring is still required after feeding and mixing with other foaming materials. The more precise the concentration of the calcium carbonate solution, the higher the quality of the foamed product. However, the existing method of pre-mixing and then feeding will also cause slight precipitation of the calcium carbonate solution in the material barrel after pre-stirring to a certain extent. Therefore, if stirring can be carried out while feeding during the feeding process after pre-stirring, the uniformity of the calcium carbonate solution can be further improved, thereby improving the quality of the sponge product. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a calcium carbonate pre-stirring and discharging device for the above problems existing in the prior art. The technical problem to be solved by the utility model is how to realize stirring and conveying of the calcium carbonate solution simultaneously.

[0004] The purpose of the utility model can be achieved by the following technical solutions: A calcium carbonate pre-stirring and discharging device, characterized in that it includes a material tank and a tank cover. A mixing cylinder is arranged on the tank cover, a gear box is arranged above the mixing cylinder, and a motor is arranged above the gear box. A first gear connected to the output shaft of the motor and a second gear meshing with the first gear are arranged in the gear box. A stirring shaft located in the mixing cylinder is fixedly arranged on the output shaft of the motor. The lower end of the mixing cylinder is connected with a suction pipe inserted into the bottom of the material tank. A first spiral guide vane located in the suction pipe is arranged at the lower end of the output shaft of the motor. An eccentric position of the mixing cylinder is also connected with a discharge pipe. A second spiral guide vane inserted into the discharge pipe is fixedly arranged on the second gear. The outlet of the discharge pipe is located below the tank cover. A feeding pipe is also arranged on the mixing cylinder. The number of teeth of the first gear is less than that of the second gear.

[0005] Further, stirring paddles located in the mixing cylinder are arranged on the stirring shaft.

[0006] Through differential speed setting in this solution, more materials are sucked into the mixing cylinder, while less materials are returned to the material tank. In this way, a certain positive pressure of the materials is formed in the material tank, and under the pressure difference, the materials can be forced to be discharged outside the feeding pipe. During the process of the materials entering the mixing cylinder from the suction pipe, stirring can be carried out in the mixing cylinder. Part of the stirred materials flow back to the material tank from the discharge pipe, while another part of the materials are discharged and conveyed outside through the feeding pipe. This process can ensure that the materials are stirred and fed simultaneously, and the feeding speed can also be controlled by the motor speed.

[0007] In addition, the process of pumping the materials from the bottom of the material tank to the mixing cylinder and then refluxing the materials from the mixing cylinder to the upper part of the material tank is also a process of stirring the materials. Therefore, the stirring of the materials in this solution is diversified and the mixing is more uniform. Description of the Drawings

Detailed Embodiments

[0011] The following are specific embodiments of the present invention and in combination with the drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0012] As Figure 1 and Figure 2 shown in the calcium carbonate pre-stirring discharging device, it includes a material tank 1 and a tank cover 2. A mixing cylinder 3, a gearbox 4 above the mixing cylinder 3 and a motor 5 above the gearbox 4 are arranged on the tank cover 2. A first gear 6 connected to the output shaft of the motor 5 and a second gear meshing with the first gear 6 are arranged in the gearbox 4. A stirring shaft located in the mixing cylinder 3 is fixedly arranged on the output shaft of the motor 5. The lower end of the mixing cylinder 3 is connected with a suction pipe 8 inserted into the bottom of the material tank 1. A first spiral guiding piece 9 located in the suction pipe 8 is arranged at the lower end of the output shaft of the motor 5. An eccentric position of the mixing cylinder 3 is also connected with a discharging pipe 10. A second spiral guiding piece 11 inserted into the discharging pipe 10 is fixedly arranged on the second gear. The outlet of the discharging pipe 10 is located below the tank cover 2. A feeding pipe 12 is also arranged on the mixing cylinder 3. The number of teeth of the first gear 6 is less than that of the second gear. Stirring paddles 13 located in the mixing cylinder 3 are arranged on the stirring shaft.

[0013] In this solution, through differential speed setting, more materials are sucked into the mixing cylinder 3, while less materials are returned to the material tank 1. In this way, a certain positive pressure of the materials is formed in the material tank 1. Under the pressure difference, the materials can be driven to be discharged outside through the feeding pipe 12. During the process of the materials entering the mixing cylinder 3 from the suction pipe 8, the materials can be stirred in the mixing cylinder 3. Part of the stirred materials flow back to the material tank 1 from the discharging pipe 10, while another part of the materials is discharged and conveyed outside through the feeding pipe 12. This process can ensure that the materials are stirred and fed at the same time, and the feeding speed can also be controlled by the rotation speed of the motor 5.

[0014] In addition, the process of pumping the material from the bottom of the material tank 1 to the mixing cylinder 3 and then the mixing cylinder 3 flowing back to the upper part of the material tank 1 is also a process of stirring the material. Therefore, the stirring of the material in this solution is diversified and the mixing is more uniform.

[0015] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar means for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
