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

[0028] Embodiment two, such as figure 2 As shown, the automatic precision type Mannheim reactor feeding device of the present invention is to configure the feeder 2 at the lower end of the potassium chloride feeding bin 1, and the electronic belt weigher 3 is arranged below the feeder 2, and the electronic belt weighs 3 below the discharge end. Equipped with feeding hopper 4 matched with the feeding port of potassium chloride of Mannheim furnace; connecting Mannheim sulfuric acid feeding pipe 5 with electronically controlled metering valve 6, the metering result signal output end of electronic belt scale 3 is connected with feeding automatic controller 7 The input end of the potassium chloride feeding weight signal, the output end of the sulfuric acid feeding amount control signal of the automatic feeding controller 7 is connected to the control signal input end of the electronic control metering valve 6.

[0029]The feed hopper 4 is equipped with a rotary drive. The inner c...

Embodiment 3

[0030] 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

[0031] Embodiment four, such as Figure 4 As shown, the difference between the automatic and precise Mannheim reactor feeding device of the present invention and Embodiment 2 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 is The spiral feeding plate 41 (or being shaped on the hollow spiral feeding plate of vertical through-hole for the center, or being the solid plate type spiral feeding plate, or being the feeding teeth of the helical arrangement fixed on the central shaft) that the central shaft 44 is fixedly installed ). 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 plate 41 (or stirrin...

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...
