High-speed mixer for powder calcium-zinc stabilizer

Abstract

This utility model discloses a high-speed mixer for powdered calcium-zinc stabilizers, including a mixer with a conical bottom and a support pile at the lower end. A feed chute is connected to the top surface of the mixer, and a first motor is fixedly installed at the upper center of the mixer. This utility model uses the first motor to drive a spiral stirring rod, an L-shaped connecting block, a rectangular stirring plate, and a conical stirring block to rotate simultaneously. This causes the spiral stirring rod to continuously tumble the raw material at the conical bottom of the mixer, while the rectangular stirring plate and conical stirring block continuously stir the raw material, preventing it from adhering to the inner wall of the mixer and effectively improving the mixing effect. A second motor drives four cross-shaped rectangular pusher plates on the connecting rod to rotate. These four rectangular pusher plates, in conjunction with several segmented pieces in the rectangular channel, quickly disperse and push the raw material into the discharge bin, improving discharge efficiency while preventing discharge blockage.

Description

Technical Field

[0001] This utility model relates to the field of calcium-zinc stabilizer production technology, and in particular to a high-speed mixer for powdered calcium-zinc stabilizers. Background Technology

[0002] Calcium-zinc stabilizers are produced using a unique composite processing technology with calcium, zinc salts, lubricants, and antioxidants as key components. They have certain lubricity, poor transparency, and are prone to blooming. Powdered calcium-zinc stabilizers are the most widely used non-toxic PVC stabilizers and are commonly used in food packaging, medical devices, and wire and cable materials.

[0003] Existing powdered calcium-zinc stabilizer mixers often suffer from problems in actual use, where the powdered raw materials tend to adhere to the inner wall of the machine or deposit on the bottom of the machine, resulting in poor mixing performance. Furthermore, the lack of an anti-clogging discharge structure at the outlet affects the discharge efficiency. To address these issues, a high-speed powdered calcium-zinc stabilizer mixer is proposed. Utility Model Content

[0004] To address the shortcomings and defects in existing technologies, this utility model proposes a high-speed mixer for powdered calcium-zinc stabilizers. This invention solves the technical problems in existing powdered calcium-zinc stabilizer mixers where, in actual use, the powdered raw materials tend to adhere to the inner wall of the machine or deposit on the bottom of the machine, resulting in poor mixing effect. Furthermore, the lack of an anti-clogging material discharge structure at the discharge port affects the discharge efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A high-speed mixer for powdered calcium-zinc stabilizer includes a mixer with a conical bottom and a support pile at the lower end. A feed chute is connected to the top surface of the mixer. A first motor is fixedly installed at the upper center of the mixer. A rotating shaft is fixedly installed at the lower end of the drive shaft of the first motor. The rotating shaft vertically penetrates the top surface of the mixer. A spiral stirring rod is provided at the lower end of the rotating shaft. A mixing mechanism is provided on the annular sidewall of the spiral stirring rod near the rotating shaft. A discharge pipe is connected to the conical bottom of the mixer, and an anti-blocking mechanism is provided at the lower end of the discharge pipe.

[0006] Preferably, a coupling is fixedly installed at the lower end of the rotating shaft, and the upper end of the spiral stirring rod is fixedly connected to the coupling.

[0007] Preferably, the mixing mechanism includes two L-shaped connecting blocks fixedly connected to the annular sidewall of the spiral stirring rod near the rotating shaft. The spiral stirring rod is located between the vertical sections of the two L-shaped connecting blocks. A rectangular stirring plate and a conical stirring block are fixedly connected to the sidewalls of the vertical sections of the two L-shaped connecting blocks away from the spiral stirring rod. The two conical stirring blocks are inserted into the conical bottom of the mixer. The sidewalls of the two rectangular stirring plates and the conical stirring blocks are closely attached to the inner wall of the mixer.

[0008] Preferably, both rectangular stirring plates are provided with a number of equally spaced strip-shaped openings, and the spiral stirring rod, L-shaped connecting block, rectangular stirring plate and conical stirring block are all corrosion-resistant alloy products.

[0009] Preferably, the anti-blocking mechanism includes a regulating valve connected to the lower end of the discharge pipe, the lower end of the regulating valve connected to a discharge hopper, the bottom of the discharge hopper being conical, a mounting bracket fixedly installed on the right side wall of the discharge hopper, a second motor fixedly installed at the end of the mounting bracket away from the discharge hopper, a connecting rod fixedly connected to the drive shaft of the second motor, the connecting rod being horizontally rotatable through the inner walls of the left and right sides of the discharge hopper, and four rectangular push plates fixedly connected to the connecting rod on the annular side wall inside the discharge hopper.

[0010] Preferably, the four rectangular pusher plates are arranged in a cross shape, and each of the four rectangular pusher plates has a rectangular through groove at its center. Several equally spaced dividing pieces are fixedly connected to the inner walls of the long sides of the four rectangular through grooves.

[0011] Compared with the prior art, the advantages of this utility model are as follows: 1. The first motor drives the spiral stirring rod, L-shaped connecting block, rectangular stirring plate and conical stirring block to rotate simultaneously. This causes the spiral stirring rod to continuously turn the raw material in the conical bottom of the mixer, while the rectangular stirring plate and conical stirring block continuously stir the raw material, preventing the raw material from sticking to the inner wall of the mixer, thus effectively improving the mixing effect.

[0012] 2. The second motor drives the four rectangular pusher plates distributed in a cross shape on the connecting rod to rotate. The rotation of the four rectangular pusher plates, together with the several dividing pieces in the rectangular through slot, quickly disperses and pushes the raw materials in the discharge bin, improving the discharge efficiency while preventing discharge blockage.

[0018] A mixing mechanism is provided on the annular sidewall of the spiral stirring rod 6 near the rotating shaft 5. The mixing mechanism includes two L-shaped connecting blocks 9 fixedly connected to the annular sidewall of the spiral stirring rod 6 near the rotating shaft 5.
