Problems solved by technology

[0004] The raw material potassium chloride of the existing Mannheim reactor is fed through a screw conveyor with a frequency converter. Due to the different dry humidity of the raw material potassium chloride and the uneven particle size, the feeding is unstable, resulting in product control. Unstable, even sometimes large fluctuations, resulting in unqualified products and affecting production efficiency

Embodiment 2

[0026] Embodiment two, such as figure 2 As shown, the automatic and precise Mannheim reactor feeding device of the utility model is configured with a feeder 2 at the lower end of the potassium chloride feeding bin 1, and an electronic belt weigher 3 is arranged below the feeder 2, and the discharge end of the electronic belt scale 3 The lower part is equipped with a feeding hopper 4 that matches the feeding port of potassium chloride in the Mannheim furnace; the feeding pipe 5 connected with Mannheim sulfuric acid is equipped with an electronically controlled metering valve 6, and the metering result signal output end of the electronic belt scale 3 is connected to the feeding automatic controller The potassium chloride feed weight signal input end of 7, the sulfuric acid feed amount control signal output end of the automatic feed controller 7 is connected to the control signal input end of the electronic control metering valve 6.

[0027] The feed hopper 4 is equipped with a ro...

Embodiment 3

[0028] Embodiment three, such as image 3 As shown, the difference between the automatic and precise Mannheim reactor feeding device of the present invention and Embodiment 2 is that the spiral feeding plate 41 is a hollow spiral feeding plate with a vertical central through hole 40 .

Embodiment 4

[0029] Embodiment four, such as Figure 4 As shown, the difference between the automatic and precise Mannheim reactor feeding device of the utility model and the second embodiment is that: a screw feeder driven by a rotary drive device is arranged in the feeding cavity of the feeding hopper 4, and the screw feeder Be the spiral feeding plate 41 that central shaft 44 is installed (or be the center is shaped on the hollow spiral feeding plate of vertical through hole, perhaps be the solid plate type spiral feeding plate, perhaps be the feeding material that is arranged on the helical shape that is fixed on the central shaft tooth). The spiral conveying plate can also be called a stirring cage. The rotary driving device includes a variable frequency motor 82 controlled by an automatic controller, and the variable frequency motor 82 drives the screw feeder through a reduction transmission mechanism. More specifically: the upper end of the central shaft 44 and the screw feeding p...

Abstract

The invention relates to a method and a device for accurately feeding a mannheim reaction furnace, aiming to solve the problem that the feeding proportion of the conventional mannheim reaction furnace cannot be ensured. The feeding is ensured by arranging a feeder at a material outlet of a potassium chloride feed bin; a electronic belt scale is arranged between the feeder and a potassium chloride feed port of a mannheim furnace to accurately measure the potassium chloride feeding amount or the potassium chloride feeding speed in real time; a sulfuric acid feed pipe of the mannheim furnace is provided with an electric control metering valve to accurately control the sulfuric acid feeding amount or the sulfuric acid feeding speed in real time; and an automatic controller is used for extracting the potassium chloride feeding amount or the potassium chloride feeding speed measured by the belt scale in real time, controlling the electric control metering valve in real time according to the potassium chloride feeding amount or the potassium chloride feeding speed and controlling the potassium chloride feeding amount and the sulfuric acid feeding amount within a specified percentage range all the time. The device has the advantages of ensuring the feeding proportion; ensuring the product quality; improving the product yield and the production efficiency; and making the product quality stable and constant.

Description

technical field [0001] The invention relates to feeding equipment for a Mannheim furnace, in particular to a precise feeding method and device for a Mannheim reactor. Background technique [0002] The existing Mannheim furnace is made of high-temperature refractory bricks, heavy and light insulation bricks, and ordinary red bricks. The whole furnace uses steel structures as supports, bricks as entities, and insulation materials as the key. The furnace is composed of combustion chamber (heating chamber), reaction chamber, flue, stirring rake, burner (two), potassium chloride feeding port, sulfuric acid feeding pipe, feeding port, etc., and the stirring rake is below the potassium chloride feeding port. The top distributor, under the sulfuric acid feeding pipe is an annular sulfuric acid guide groove located in the center of the reaction section. The furnace has two cavities: the middle elliptical cavity is the reaction chamber, and there is a stirring rake in the cavity. Dur...
