The GUPVC plate sewage plant gas sampling cover of can pegging graft
Technical field
The present invention relates to a kind of foul gas gathering-device, specifically a kind of GUPVC plate sewage plant gas sampling cover of pegging graft.
Background technology
At present, the structures of Sewage Disposal (or sewage treatment plant) are mostly open type pond, and the dilution of foul gas and diffusion in sewage, have a strong impact on Sewage Disposal surrounding enviroment.
For addressing this problem, the way conventionally adopting is to collect foul gas, then focuses on.< < sewage treatment plant foul gas is collected and discharge design > > (old newly < < petrochemical technology > > 2009.16(3) is concentrated in high-altitude: the scheme that 37) has proposed a kind of collecting hood, it adopts anti-flammability fiberglass, oxygen index (OI) is not less than 30, and thickness is 8~12cm.
According to the knowledge of the applicant, domestic manufacturer generally also adopts the collecting hood of following centralized system: stainless steel insert+sunlight board, stainless steel insert+glass epoxy, stainless steel frame+dull and stereotyped implosion guard, modular fibreglass reinforced plastic cover, stainless steel insert+sandwich color steel plate etc.
The collecting hood applicant of prior art thinks, exists following not enough: 1) cost is high, and the life-span is short, and average life span is about 10 years; 2) maintenance, dismounting inconvenience; 3) need to design separately according to the different situations of each sewage treatment plant, design, construction are slowly.
Summary of the invention
The invention provides a kind of GUPVC of pegging graft plate sewage plant gas sampling cover, it can be assembled at the scene without professional, dismantle easy, construction fast, can be applied to rapidly all kinds of Sewage Plant, slaughterhouse, food processing factory etc., its Stability Analysis of Structures, and have uvioresistant, resistance to hydrogen sulfide, the feature such as acidproof, alkaline-resisting, high temperature resistant, anti-oxidant, resistance to deformation, reaches 20 years service life.
The concrete technical scheme adopting of the present invention is:
A kind of GUPVC plate sewage plant gas sampling cover of pegging graft, it is characterized in that, described collecting hood is pegged graft and is formed by a plurality of plugboards, described plugboard body is hollow platy structure, its inside is provided with reinforcement, and the two ends of plugboard are respectively equipped with half tubular connecting portion, and the tubular connecting portion mating with half tubular connecting portion, between half tubular connecting portion, tubular connecting portion and plugboard body, be equipped with four the first fixed heads that are mutually mirror image, the first fixed head slopes inwardly.
The present invention also comprises fastener, and described fastener comprises level board and two the second fixed heads that are mutually mirror image, and the second fixed head slopes inwardly, and its inclination angle and the first fixed head match.
For ease of forming various shape, the present invention also comprises work template.
Described plugboard material is hard PVC (GUPVC), and its raw material by following weight portion is made:
PVC100 part, calcium carbonate 3-10 part, DOP3-4 part, DOA0-1 part, ACR0.5-1 part, paraffin 0.2-0.8 part, titanium dioxide 0.5-3 part, anti ultraviolet agent 0.2-1 part, calcium zinc stabilizer 2-5 part.
Above-mentioned raw materials is commercial goods, and wherein anti ultraviolet agent can be selected UV-531, UV-236, UV-236 etc., and calcium zinc stabilizer can be selected CZ-1, CZ-2 etc.
Plugboard of the present invention adopts the technique of prior art to make, and production, the forming method of its technique and ordinary rigid PVC are basic identical.
Compared with prior art, advantage of the present invention is:
(1) service life of the present invention 15-20, compared with prior art, cost is low;
(2) collecting hood of the present invention is white, can effectively reflect sunlight, controls and collects case temperature substantially constant; Its attractive in appearance, smooth surface, dust fall is convenient to clean.There is uvioresistant, resistance to hydrogen sulfide, the advantage such as acidproof, alkaline-resisting, high temperature resistant, anti-oxidant.
(3) can carrying personnel operation.This kind of structural design has short construction period, good looking appearance, and be convenient to dismounting, as needs, clear up pond body or repair apparatus and can dismantle at any time and can repeat assembled use.

The specific embodiment
As shown in Figure 1, plugboard body is hollow platy structure, its inside is provided with reinforcement 4, the two ends of plugboard are respectively equipped with half tubular connecting portion 1, with the tubular connecting portion 5 mating with half tubular connecting portion 1, between half tubular connecting portion 1, tubular connecting portion 5 and plugboard body, being equipped with four the first fixed head 2, the first fixed heads 2 that are mutually mirror image slopes inwardly.
As shown in Figure 3, described fastener comprises that level board 6 and two the second fixed head 7, the second fixed heads 7 that are mutually mirror image slope inwardly, and its inclination angle and the first fixed head 2 match.
As shown in Figure 2, between different plugboards, head and the tail are pegged graft, and fix with fastener.
As shown in Figure 4, adopt a plurality of plugboards can be assembled into the collecting hood form with arc.
Described plugboard material is hard PVC, and its raw material by following weight portion is made:
PVC100 part, calcium carbonate 3-10 part, DOP3-4 part, DOA0-1 part, ACR0.5-1 part, paraffin 0.2-0.8 part, titanium dioxide 0.5-3 part, anti ultraviolet agent 0.2-1 part, calcium zinc stabilizer 2-5 part.
