Description

Technical Field

[0001] This utility model relates to the field of sponge technology, and more specifically, it relates to an environmentally friendly mixing device for sponge processing. Background Technology

[0002] The production of environmentally friendly sponges requires the use of mixing equipment to mix raw materials. However, existing sponge foaming mixing kettles have poor mixing effects between the sponge foaming raw materials and gas during the sponge foaming process. Insufficient mixing with gas can easily lead to a decrease in the quality of the finished product and reduce the pass rate of the sponge production process.

[0003] To address the aforementioned issues, Chinese Patent Publication No. CN215589776U discloses a sponge foaming mixing tank. The sponge foaming mixing tank includes a mixing chamber. A fixed plate is vertically mounted on the rear side of the top of the mixing chamber, and a motor is vertically mounted on the front side of the fixed plate. A rotating shaft is vertically mounted on the output shaft of the motor, and the bottom end of the rotating shaft rotatably extends into the inner cavity of the mixing chamber. This solution increases the air pressure inside the air injection chamber during the descent of the extrusion plate, allowing airflow to be injected into the interior of the mixing chamber through an injection pipe. This airflow mixes with the raw materials being stirred at the bottom of the mixing chamber, resulting in better mixing of the sponge foaming material and the gas.

[0004] This utility model also proposes a new solution to this problem. Utility Model Content

[0020] Reference Figures 1-2An environmentally friendly sponge processing mixing device includes a mixing vessel 1. The top and bottom of the mixing vessel 1 are respectively provided with an inlet pipe and an outlet pipe. A first mixing shaft 2 is vertically arranged at the center of the mixing vessel 1. The first mixing shaft 2 has a hollow structure. The upper end of the first mixing shaft 2 passes through the mixing vessel 1 and is rotatably connected to a connecting pipe 3. The connecting pipe 3 is fixedly installed on the top of the mixing vessel 1. An air pump 4 is fixedly installed on the mixing vessel 1. The air outlet of the air pump 4 is connected to the connecting pipe 3. Several air supply holes are axially opened on the first mixing shaft 2, and air supply pipes 5 are fixedly installed on each of the air supply holes. A first mixing part is provided on the first mixing shaft 2. Several second mixing shafts 6 are arranged in a ring array on the outer side of the first mixing shaft 2. A second mixing part is provided on each of the several second mixing shafts 6, and a connecting frame 7 is fixedly fixed at the upper end of the several second mixing shafts 6. The connecting frame 7 is fixedly sleeved on the first mixing shaft 2. A drive mechanism for driving the first mixing shaft 2 to rotate is provided on the top of the mixing vessel 1.

[0021] Additionally, the ends of several gas supply pipes 5 away from the first stirring shaft 2 are all bent downwards. This design optimizes the gas injection angle, thereby preventing raw materials from entering the gas supply pipes 5 and clogging them when gas injection stops.

[0022] The first stirring section includes several first stirring rods 8 evenly distributed along the axial direction of the first stirring shaft 2. The several first stirring rods 8 are all fixed perpendicularly to the first stirring shaft 2, and several second stirring rods 9 are fixed perpendicularly on each of the several first stirring rods 8. The first stirring rods 8 and the second stirring rods 9 work together to form a multi-stirring structure, which ensures the stirring effect and ensures the full mixing of raw materials and gas.

[0023] The second stirring section includes several third stirring rods 10 evenly distributed along the axial direction of the second stirring shaft 6. The two ends of the third stirring rods 10 are respectively fixed with first stirring blades 11 and second stirring blades 12. The first stirring blades 11 and second stirring blades 12 are both spiral in shape and are centrally symmetrical about the axis of the second stirring shaft 6. The third stirring rods 10 and the first stirring blades 11 and second stirring blades 12 at both ends generate stirring force. In particular, the spiral shape of the first stirring blades 11 and second stirring blades 12 generates a more complex flow pattern during the stirring process, thereby further optimizing the stirring effect and helping to achieve uniform gas distribution in the raw materials.

[0024] The drive mechanism includes a bracket 13 fixedly mounted on the mixing vessel 1, a motor 14 fixedly mounted on the bracket 13, a drive gear 15 fixedly mounted on the output end of the motor 14, and a driven gear 16 coaxially fixed on the first stirring shaft 2. The driven gear 16 meshes with the drive gear 15. The motor 14 drives the first stirring shaft 2 to rotate through the meshing of the drive gear 15 and the driven gear 16, thereby realizing the stirring function. The structure is simple and reliable, with high transmission efficiency and easy maintenance and adjustment.

[0025] Working principle: During use, the raw materials for preparing the sponge are added into the mixing vessel 1 through the feed pipe. During operation, the vacuum pump 4 draws the required gas through the connecting pipe 3. After the gas enters the hollow cavity of the first stirring shaft 2, it is evenly dispersed into the sponge foaming raw material in the mixing vessel 1 through the air delivery hole and the air delivery pipe 5. The drive mechanism drives the first stirring shaft 2 to rotate, and drives the connecting frame 7 and the second stirring shaft 6 on the connecting frame 7 to rotate simultaneously. The first stirring part and the second stirring part work together to strongly stir the sponge foaming raw material, ensuring that the gas and raw material are fully mixed, improving the stirring efficiency and mixing uniformity, avoiding the problem of reduced product quality due to uneven mixing, thereby improving the production quality of the sponge. The fully mixed material is discharged from the mixing vessel 1 through the air outlet pipe.

[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
