Description

Technical Field

[0001] This utility model relates to the field of mixing equipment, and in particular to a high-efficiency and energy-saving mixing equipment. Background Technology

[0002] Currently, before processing PVC pipes and profiles, the various raw materials in the production formula need to be mixed, stirred, heated, and cooled to ensure that the materials are fully integrated and pre-plasticized before entering the extruder for processing. Existing mixing equipment is all at public frequency, and even before the materials have been weighed and mixing has begun, the hot and cold pots (driven by two 200KW motors) of the equipment are still rotating at high speed, resulting in high electricity consumption.

[0003] Therefore, in order to reduce energy consumption, it is necessary to improve and optimize the problem of "hot pot and cold pot running at high speed during the raw material proportioning / weighing process" mentioned in the background above. Utility Model Content

[0004] In order to solve the problems in the background art, this utility model adopts the following technical solution:

[0005] A high-efficiency and energy-saving mixing device includes a mixing pot and a stirring motor installed at the bottom of the mixing pot and rotating thereon. The mixing pot has an inlet and an outlet at the top and near the bottom of the front side, respectively. It also includes multiple weighing cylinders. An inverter with electrical connection is fixedly installed on the outside of the stirring motor. A mounting frame is fixedly connected to the outside of the inlet at the top of the mixing pot, and the mounting frame is used to fix the multiple weighing cylinders. The bottom of the weighing cylinder is connected to the inlet at the top of the mixing pot through a discharge pipe. The top of the weighing cylinder is also provided with a feeding port.

[0006] Preferably, a weighing frame is movably disposed inside the weighing cylinder, a base plate is disposed at the bottom of the upper end of the weighing frame, and a pressure sensor is disposed between the base plate and the upper end face of the weighing frame, while a display panel electrically connected to the pressure sensor is disposed on the front of the weighing cylinder.

[0007] Preferably, the weighing cylinder has a rotating shaft fixedly connected to both the front and back sides, and the rotating shaft is rotatably connected to the inner wall of the weighing cylinder. A weighing motor is fixedly connected to the front of the weighing cylinder, and the power end of the weighing motor moves through the weighing cylinder and is fixedly connected to the outside of the rotating shaft.

[0008] Preferably, inclined guide blocks are fixedly installed on the inner wall of the weighing cylinder at both the upper and lower ends of the weighing frame. The bottom of the upper guide block is connected to the upper end of the weighing frame, and the lower guide block is connected to the upper end of the feeding pipe.

[0009] Preferably, the feeding tube is a transparent plastic tube.

[0010] Preferably, an electrically controlled valve is provided on the outside of the feed inlet.

[0011] Compared with the prior art, the present invention has the following beneficial effects;

[0012] This invention, by installing a frequency converter matched to the mixing motor and an automatic weighing cylinder with a valve, reduces the rotational speed / power of the mixing motor in the mixing pot to 50% of its original power before the material enters the mixing pot, thereby reducing electricity consumption by half. After the material proportions are completed and the valve is opened to allow the material to enter the mixing pot, the rotational speed and power of the mixing motor are restored to 100% of their original power to ensure normal mixing of the material. Through the frequency conversion improvement of the mixing equipment, energy consumption during standby and idling processes can be controlled, thereby reducing the electricity consumption during the raw material mixing process.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A high-efficiency and energy-saving mixing device includes a mixing pot 1 and a stirring motor 4 that is set at the bottom of the mixing pot 1 and rotates thereon. The mixing pot 1 has an inlet 2 and an outlet 3 at the top and near the bottom of the front, respectively. It also includes multiple weighing cylinders 7. A frequency converter 5 that is electrically connected is fixedly installed on the outside of the stirring motor 4. A mounting bracket 6 is fixedly connected to the outside of the inlet 2 at the top of the mixing pot 1. The mounting bracket 6 is used to fix the multiple weighing cylinders 7. The bottom of the weighing cylinders 7 is connected to the inlet 2 at the top of the mixing pot 1 through a discharge pipe 8. A feeding port 9 is also provided at the top of the weighing cylinders 7. The weighing cylinder 7 has a weighing frame 701 that is movably installed inside. A base plate 702 is installed at the bottom of the upper end of the weighing frame 701. A pressure sensor is installed between the base plate 702 and the upper end of the weighing frame 701. A display panel 10 electrically connected to the pressure sensor is installed on the front of the weighing cylinder 7. A rotating shaft 703 is fixedly connected to both the front and back of the weighing cylinder 7. The rotating shaft 703 is rotatably connected to the inner wall of the weighing cylinder 7. A weighing motor 704 is fixedly connected to the front of the weighing cylinder 7. The power end of the weighing motor 704 moves through the weighing cylinder 7 and is fixedly connected to the outside of the rotating shaft 703. Inclined guide blocks 705 are fixedly installed on the inner wall of the weighing cylinder 7 at the upper and lower ends of the weighing frame 701. The bottom of the upper guide block 705 is connected to the upper end of the weighing frame 701, and the lower guide block 705 is connected to the upper end of the feed pipe 8. The feed pipe 8 is a transparent plastic pipe. An electrically controlled valve 11 is installed on the outside of the feed inlet 2.

[0022] Based on the above structural setup, when the device is idle, the rotational speed / power of the mixing motor 4 in the mixing pot is reduced to 50% of its original power. During the feeding process, the operator pre-introduces different raw materials from the feeding ports 9 at the top of different weighing cylinders 7, and guides them precisely into the upper part of the weighing frame 701 via the guide block 705. The pressure sensor at the bottom of the upper plate 702 of the weighing frame 7 is then pressed, and the material weight is displayed on the display panel 10. Feeding stops once the expected weight is reached. Then, the weighing motor 704 is started via an external switch, and the weighing frame 701 is rotated via the rotating shaft 703. This allows the internal raw materials to be guided through the guide block 705 to the discharge pipe 8, where they slide down to the inlet 2. Observing the transparent inlet 8, once all the raw materials in all the discharge pipes 8 have entered the inlet 2, the electrically controlled valve 11 on the outside of the inlet 2 is opened. At this time, the electrically controlled valve 11 is electrically connected to the frequency converter 5 on the outside of the mixing motor 4 via the PLC controller, thereby adjusting the mixing motor 4. The speed and power can be adjusted to 100% of the original speed for operation. Through the frequency conversion improvement of the above mixing equipment, the energy consumption during standby and idling can be controlled, thereby reducing the power consumption of the raw material mixing process.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
