Abstract
The invention discloses an explosion-proof device, in particular to a gas explosion-proof device used for a titanium slag smelting furnace. The invention aims to provide the explosion-proof device which can effectively reduce the pressure when the pressure in a furnace body of the titanium slag smelting furnace is beyond a safety value. According to the explosion-proof device, a furnace body explosion-proof opening communicated with the inner chamber of the furnace body is formed in the furnace body, and an explosion-proof column is mounted in the furnace body explosion-proof opening; a sealing surface is formed between the explosion-proof column and the furnace body explosion-proof opening, and the explosion-proof column is connected with a balancing weight through a balance weight connecting rod. The explosion-proof device has the advantages of being simple in structure, safe and reliable and low in investment and maintenance cost.
Description
Technical field
The present invention relates to a kind of explosion-proof equipment, in particular for the gas explosion-proof equipment of titanium slag smelting furnace.
Background technology
The Panzhihua Region of China stores a large amount of sefstromite, and Ti industry development is very fast.Having many uses of titanium, wherein titanium dioxide is widely used in the industry such as coating, plastics, papermaking, chemical fibre, rubber, makeup, food.The smelting technology generally adopted at present produces titanium slag, and electric furnace is divided into 3 types: closed electric furnace smelting, semi closed electrosmelting and uncovered electrosmelting.
Owing to will produce a large amount of flue dust and toxic and harmful when smelting, what generally adopt at present is closed electric furnace.And when closed electric furnace is smelted, in body of heater, pressure will be produced, if pressure-controlling is improper, may blast or equipment damage, even cause personal injury, therefore reduce pressure in body of heater when body of heater pressure exceedes danger threshold, preventing from exploding is the problem that must solve.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of explosion-proof equipment that can effectively reduce pressure when titanium slag smelting furnace body of heater internal pressure exceedes safety value.
The present invention solves its technical problem and adopts titanium slag furnace explosion-proof equipment, and body of heater is provided with the body of heater venting with body of heater inner space; In body of heater venting, anti-explosion post is installed; Trim is formed between above-mentioned anti-explosion post and body of heater venting; Above-mentioned anti-explosion post is connected with balancing weight by counterweight connecting rod.
The inwall of body of heater venting is provided with boss, between described anti-explosion post lower surface and the upper surface of above-mentioned boss, forms trim; Gap is provided with between anti-explosion post and body of heater venting inwall.
The internal diameter of described anti-explosion post diameter and body of heater venting is adaptive, and is formed with trim between anti-explosion post outer circumference surface and venting inwall; Inclined-plane is provided with as pressure release face at the inner segment of anti-explosion post.
Described pressure release face is less than 1/2 of anti-explosion post cross-sectional area in cross section shadow area.
Described counterweight connecting rod is provided with return spring.
Adopt titanium slag furnace explosion-proof equipment of the present invention, structure is simple, safe and reliable, investment and maintenance cost low.

Embodiment
Be described in detail below in conjunction with the specific works process of accompanying drawing to titanium slag furnace explosion-proof equipment of the present invention.
Titanium slag furnace explosion-proof equipment of the present invention, be included in body of heater 1 is arranged with the body of heater venting 2 of body of heater inner space, anti-explosion post 3 is installed in body of heater venting 2.Trim 8 is formed between anti-explosion post 3 and body of heater venting 3.In normal smelting process, above-mentioned trim 8 prevents the gas in body of heater 1 and heat from leaking from body of heater venting 2, and when the pressure in body of heater 1 exceeds danger threshold, anti-explosion post 3 upwards rises opens trim 8, gas in body of heater 1 is discharged from body of heater venting 3, eliminates the hidden peril of explosion that furnace pressure is excessive.Simultaneously anti-explosion post 3 is connected with balancing weight 5 by counterweight connecting rod 7, and the first passes through the weight of balancing weight 5 can gas safety value in regulating stove, and it two is after furnace gas is lower than safety value, and anti-explosion post 3 can reset, and again reaches the effect of sealing.
Embodiment one: as shown in Figure 1, the inwall of body of heater venting 2 is provided with boss 21, and anti-explosion post 3 is placed on boss 21, forms trim 8 between the upper surface of anti-explosion post 3 lower surface and above-mentioned boss 21.Gap is provided with between anti-explosion post 3 outer circumference surface and body of heater venting 2 inwall, when furnace pressure exceedes safety value, anti-explosion post 3 rises, and furnace gas discharges from gap between anti-explosion post 3 lower surface and the upper surface of above-mentioned boss 21 and between anti-explosion post 3 outer circumference surface and body of heater venting 2 inwall.
Embodiment two: as shown in Figure 2, the internal diameter of anti-explosion post 3 diameter and body of heater venting 2 is adaptive, ensure anti-explosion post 3 can and under the requirement moved up and down at body of heater venting 2, between anti-explosion post 3 outer circumference surface and venting 2 inwall, be formed with trim 8.Be provided with inclined-plane as pressure release face 4 at anti-explosion post 3 inner segment be inserted into inside body of heater venting 2 simultaneously.When furnace pressure exceedes safety value, anti-explosion post 3 rises, and after pressure release face 4 exceedes body of heater venting 2 upper surface, furnace gas discharges.As shown in Figure 3, described pressure release face 4 is less than 1/2 of anti-explosion post 3 cross-sectional area in cross section shadow area, and like this in anti-explosion post 3 rise and reseting procedure, the outer circumference surface of anti-explosion post 3 can play guide effect.
In the above two embodiments, the structure of embodiment one is simple, but reliability is not as embodiment two.
In the above two embodiments, also on described counterweight connecting rod 7, return spring 6 is installed, ensures that anti-explosion post 3 can effectively reset after rise is opened like this and reseal.
Although below describe the present invention in detail in conjunction with the accompanying drawings and embodiments; but those of ordinary skill in the art should be clear; when not departing from claim spirit and scope, various amendment can be carried out to above-described embodiment, being all within protection scope of the present invention.
