Description

Technical Field

[0001] This utility model relates to the field of chemical raw material processing technology, specifically a chemical raw material mixing device. Background Technology

[0002] In the field of chemical production, the uniformity of raw material mixing directly determines the performance and quality of the final product. For example, if pigments, fillers and resins are not mixed evenly in coating production, it will lead to differences in coating color; in the synthesis of pharmaceutical intermediates, large deviations in the raw material ratio may affect the efficacy of the drug or produce impurities.

[0003] The mixing device consists of an automatic feeding system, a precision temperature-controlled mixing tank, a mixing uniformity monitoring module, an exhaust gas treatment unit, and a PLC control system. According to the preset formula, the automatic feeding system feeds the raw materials into the mixing tank in proportion. The jacket is circulated with heat transfer oil or cooling water to control the temperature inside the tank. The double helix agitator and vibrator work together to achieve material mixing. The monitoring module detects the uniformity in real time. After the uniformity is met, the material is discharged. The exhaust gas is treated and discharged in compliance with standards.

[0004] However, the above-mentioned equipment has obvious shortcomings in use. Traditional chemical mixing devices are mostly designed with a single mixing tank, relying on a single set of mixing paddles at the bottom or top for mixing. The raw materials form a dead zone in the tank, and high-density raw materials are easy to settle at the bottom of the tank. It is necessary to extend the mixing time to achieve initial mixing, resulting in low production efficiency, which is far below the requirements of continuous chemical production. In view of this, we propose a chemical raw material mixing device. Utility Model Content

[0005] The purpose of this invention is to provide a chemical raw material mixing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A straight rod is fixedly installed at the bottom motor output end, and a bottom auger propeller is fixedly installed on the straight rod. A bottom filter plate is fixedly installed on the lower connecting square tube.

[0011] In a further embodiment, discharge funnel pipes are fixedly installed at the bottom of the No. 1 and No. 2 mixing tanks, and a No. 1 valve is fixedly installed on the discharge funnel pipes. A No. 2 valve is installed on the No. 1 and No. 2 feeding pipes.

[0012] In a further embodiment, the long rod, top auger paddle, top filter plate, bottom motor, straight rod, bottom auger paddle, bottom filter plate, discharge funnel pipe, valve number one, valve number two, and top motor are provided in multiple sets.

[0013] In a further embodiment, the upper connecting square tube and the lower connecting square tube are provided with circular grooves inside. The top auger is disposed in the circular groove of the upper connecting square tube, and the bottom auger is disposed in the circular groove of the lower connecting square tube. The top auger and the bottom auger rotate in opposite directions.

[0014] In a further embodiment, auxiliary components are provided on the No. 1 and No. 2 mixing tanks. The auxiliary components include a No. 1 mounting block, which is fixedly mounted on the No. 1 mixing tank and a No. 2 mounting block, respectively. A power motor is fixedly mounted on the No. 1 and No. 2 mounting blocks, and a round rod is fixedly mounted on the output end of the power motor. A stirring paddle is fixedly mounted on the round rod.

[0015] In a further embodiment, multiple sets of the power motor and stirring paddle are provided, with the multiple sets of the round rod and stirring paddle respectively located inside the No. 1 stirring tank and the No. 2 stirring tank.

[0017] Compared with the prior art, the present invention provides a chemical raw material mixing device, which has the following beneficial effects:

[0018] 1. This chemical raw material mixing device, in order to meet the stringent requirements for the mixing accuracy and efficiency of raw materials in chemical production, is equipped with a stirring component. This component, in conjunction with a top motor-driven long rod, drives the top auger paddle to rotate. Utilizing the rotational characteristics, the raw materials in the first mixing tank are transported and pushed to the second mixing tank through the circular groove of the upper connecting square tube. Simultaneously, a bottom motor-driven straight rod drives the bottom auger paddle to transport the raw materials in the second mixing tank, which then flow back to the first mixing tank through the lower connecting square tube, forming a bidirectional circulation and preventing raw material sedimentation.

[0019] 2. To reduce the failure rate of subsequent reactions due to uneven mixing, this chemical raw material mixing device is equipped with an auxiliary component. This component works with multiple sets of motors to drive the cylindrical rods and rotate the stirring paddles at high speed. The stirring paddle in the first mixing tank is located below the long rod and laterally disperses the raw materials conveyed by the top auger, breaking up the raw material agglomerates. The stirring paddle in the second mixing tank is located above the vertical rod and longitudinally stirs the raw materials returned by the bottom auger, ensuring that raw materials of different densities are fully mixed. The multiple sets of stirring paddles are staggered to form a three-dimensional mixing space, avoiding insufficient mixing of local raw materials. Attached Figure Description
