Abstract
The utility model discloses a device for handling blockage of a discharge spiral conveyer of a hydrogen fluoride reaction furnace, which aims to solve the blockage problem of the discharge spiral conveyer of the hydrogen fluoride reaction furnace. A blowing device is arranged at the middle part of the side surface of the casing of the spiral conveyer. According to the material properties and the present situation of equipment, the device is additionally provided with the blower device on the premise of not changing the structural dimension of the spiral conveyer, the compressed air at the pressure of 0.3-0.5 KPa is introduced into the blower device and blows for 10 minutes to loose or disperse the materials attaching on spiral blades, and then the blockage problem of the discharge spiral conveyer of the hydrogen fluoride reaction furnace is solved after the motor of the spiral conveyer is started. Through practical tests, the device has very good effect. The time for handling material blockage in the spiral conveyer is about 0.5 h, and the labor intensity is greatly reduced. The device maximally ensures continuous and stable production and reduces production cost.
Description
Technical field
The utility model relates to the treatment unit that a kind of hydrogen fluoride reaction furnace discharge worm conveyor blocks.
Background technology
The discharging spiral conveyor of hydrogen fluoride reaction stove is in operation, the character of its convey materials is subjected in combustion gas (coal gas) poor quality or the operation factor affecting such as reactant fluorite and sulfuric acid proportioning be improper because of the Reaktionsofen temperature, material reaction is insufficient in the stove, the mobile variation of material also 2～4cm spherical particle occurs, make that the conveying of material in screw machine is not smooth, the spiral obstruction causes the motor tripping operation, and worm conveyor quits work.If start worm conveyor once more, usual method is 1. behind the material jiggering in the cleaning spiral, starter motor, but discharging spiral conveyor, according to the necessary integral sealing of manufacturing technique requirent, otherwise in service will polluting environment, from discharging spiral conveyor inspection window cleaning length is that 2.87 meters materials in the spiral are obviously impossible, especially the temperature of charge in the spiral is up to 230～260 ℃, careless slightlyly just scalds the people, and security incident takes place.2. block the axle of spiral with pipe wrench, many people's whiles are jiggering by force, wastes time and energy, and gets half the result with twice the effort often, and each jiggering pipe wrench will damage 2～3, and it is very thorny to handle the interior clogged up with material of spiral.
In sum, in actual production, when choking phenomenon appears in discharging spiral conveyor operation, use two kinds of methods to handle usually, all can not adapt to production requirement, cause discontinuously, production efficiency is low, increases production cost.
The utility model content
The purpose of this utility model is to provide a kind of treatment unit of hydrogen fluoride reaction furnace discharge worm conveyor obstruction, to solve the problem that hydrogen fluoride reaction furnace discharge worm conveyor blocks.
The utility model structure is for being provided with blowing device at middle part, screw conveyor housing side.
According to the character of material and the present situation of equipment, the utility model is under the prerequisite that does not change the worm conveyor scantlings of the structure, set up blowing device cut-in pressure 0.3～0.5Kpa pressurized air, blow with pressurized air and will be blocked in the spiral material in 10 minutes and blow pine or dispel, start the worm conveyor motor then and can solve the problem that hydrogen fluoride reaction furnace discharge worm conveyor blocks.
The utility model is by the check of practice, and effect is very good.The time of handling clogged up with material in the spiral is about 0.5 hour, and labour intensity greatly reduces, and guarantees to greatest extent the continous-stable produced to have reduced production cost.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an A-A view among Fig. 1.
Embodiment
As shown in Figure 1, external-heat Reaktionsofen 3 links to each other with worm conveyor, does not change the worm conveyor scantlings of the structure, is provided with blowing device 2 at middle part, screw conveyor housing 1 side.Can adopt 4 ' steel pipe (Φ 17 * 2 * 80), feed pressure 0.3～0.5Kpa pressurized air, utilize pressurized air will be blocked in material in the spiral and blow pine or dispel.
During use, feed pressurized air and blew 10 minutes, will be blocked in the spiral material and blow pine or dispel, start screw motor 4 (during starter motor, pressurized air does not stop) then, 2～3 times repeatedly, treat that worm conveyor works well after, the closes compression air.
Claims (2)
1. the treatment unit that hydrogen fluoride reaction furnace discharge worm conveyor blocks is characterized in that: be provided with blowing device (2) at middle part, screw conveyor housing (1) bottom surface.
2. the treatment unit that hydrogen fluoride reaction furnace discharge worm conveyor according to claim 1 blocks, it is characterized in that: described blowing device (2) is a steel pipe.
