Description

Technical Field

[0001] This utility model relates to the technical field of stabilizer production equipment, and in particular to a mixing machine for PVC stabilizer production. Background Technology

[0002] PVC stabilizers inhibit the degradation of PVC molecules by replacing unstable chlorine atoms, neutralizing hydrogen chloride, and reacting with unsaturated sites, thereby increasing the thermal stability of PVC. Common PVC stabilizers include lead salt stabilizers, calcium-zinc stabilizers, liquid calcium-zinc stabilizers, liquid barium-zinc stabilizers, organotin stabilizers, and barium-cadmium paste stabilizers.

[0003] During the production of PVC stabilizers, there will inevitably be some sticky residue on the inner wall of the equipment. Over time, this will affect the quality of the next batch of PVC stabilizers, and the mixing machine is also difficult to clean.

[0004] Chinese Patent Publication No. CN217795875U, published on November 15, 2022, discloses a mixing device for PVC stabilizer production. The device includes a fixed base, a high-efficiency mixing mechanism on top of the fixed base, and a grinding mechanism on top of the fixed base. The high-efficiency mixing mechanism includes a fixed ring frame, which is fixedly welded to the top of the fixed base. A stepper motor is fixedly mounted on the top of the fixed ring frame. This invention controls a rotary motor to drive a central rotating rod to rotate. The rotating extension rod and stirring blades achieve the function of mixing the raw materials. Simultaneously, the stepper motor is controlled to drive a mixing cylinder to rotate on the inner wall of the fixed ring frame through the transmission of a drive gear and a drive gear ring, thereby achieving the function of turning the raw materials over. This avoids the problem of raw materials accumulating in dead corners during the mixing process, ensuring sufficient mixing of raw materials and improving the reliability of the device. A drawback of this invention is that the inner wall of the mixer is not scraped clean enough and is difficult to clean. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of existing mixing machines in that the inner wall is not scraped clean enough and is difficult to clean, and provides a mixing machine for PVC stabilizer production that scrapes the inner wall more cleanly and is easier to clean.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A mixing machine for producing PVC stabilizers, comprising: The mixing bucket should be placed horizontally. A rotating shaft is placed inside the mixing tank and is coaxial with the mixing tank. The two ends of the rotating shaft are engaged with the two sides inside the mixing tank. A rotating motor is placed on the outer side of the mixing barrel and connected to the mixing barrel. The shaft of the rotating motor passes through the mixing barrel and is fixedly connected to one end of the rotating shaft. Two bases are placed on the lower end of the mixing barrel, and the bases are fixedly connected to the lower end face of the mixing barrel; Several stirring scrapers are spirally arranged around a rotating shaft. The end of each stirring scraper far from the rotating shaft is in contact with the inner wall of the mixing tank. The rotation trajectory of the end of the stirring scraper far from the rotating shaft overlaps with the rotation trajectory of the adjacent end of the stirring scraper far from the rotating shaft. The end of the stirring scraper near the rotating shaft is welded to the rotating shaft. Two stirring scrapers are placed on the left and right sides of the mixing barrel, respectively. The stirring scrapers are perpendicular to the rotating shaft. The end of the stirring scraper near the rotating shaft is welded to the rotating shaft, and the end of the stirring scraper away from the rotating shaft is in contact with the inner side of the mixing barrel.

[0007] When mixing PVC stabilizer, first feed all the raw materials into the mixing barrel through the feed pipe, then turn on the rotating motor so that the rotating shaft drives the first and second stirring scrapers to continuously scrape the material adhering to the barrel wall while mixing. The movement trajectory of the first stirring scraper overlaps, so there are basically no areas that cannot be scraped. After the mixing is completed, the PVC stabilizer is discharged from the discharge pipe, achieving the purpose of cleaning the inner wall of the mixer more thoroughly.

One end of the soft scraper is in contact with the inner wall of the mixing tank, and the other end is connected to the stirring scraper rod 1 with an adhesive. A soft scraper is provided on the stirring scraper rod 2, fitted onto its outer surface and in contact with the inner side of the mixing tank.

Similarly, one end of the soft scraper is provided with a groove, and one end of the stirring scraper rod (far from the rotating shaft) is placed in the groove. The stirring scraper rod is engaged with the soft scraper through the groove. Grooves one and two allow for a tighter connection between the stirring scraper rods and the soft scraper, respectively, resulting in a more robust structure.

[0012] Preferably, the mixing drum has a slot three on one end of the rotating motor, one end of the rotating shaft is placed in the slot three, and the other end of the rotating shaft passes through the mixing drum and is fixedly connected to the shaft of the rotating motor. The slot three facilitates a more stable connection between the rotating shaft and the mixing drum.

[0013] Preferably, a handle is provided on one side of the top cover symmetrical to the hinge, and the handle is fixedly connected to the top cover. The handle facilitates the flipping of the top cover.
