Abstract

The utility model discloses a novel downward-change high-efficiency air supply port which relates to the technical field of purification equipment in the air purification industry. The novel downward-change high-efficiency air supply port comprises a high-efficiency filter mesh (1), seal strips (2), a high-efficiency air supply port box body (3), embedded screw caps (4) and fixing screws (5); both sides of the high-efficiency filter mesh (1) are respectively provided with the seal strips (2); the upper end of the high-efficiency filter mesh (1) is provided with the high-efficiency air supply port box body (3); both ends of the bottom of the high-efficiency air supply port box body (3) are respectively provided with the embedded screw caps (4) and are fixedly connected with the high-efficiency filter mesh (1) through the fixing screws (5). According to the novel downward-change high-efficiency air supply port, the defects of the prior art that the difficulty in changing consumables is great and the efficiency is low are overcome, the box body does not need to be lifted, a filter can be changed from bottom, the cost can be effectively reduced, and the air-tightness is ensured.

Description

Novel changing type highly effective air outlet down

Technical field:

The utility model relates to cleaning equipment production technical field in the air cleaning industry, relates in particular to a kind of novel changing type highly effective air outlet down.

Background technology:

Change formula at present both at home and abroad the colleague adopts and change two kinds of technologies of formula down, on change formula promptly after the limit is received in the perforate of color steel top board elder generation put into fixed frame to high efficiency particulate air filter, be held on the air outlet casing on the filter again; Utilize the casing deadweight to compress the sealing strip that carries on the filter and guarantee whole air-tightness, must stand in the time of will changing filter by the time to raise earlier on the ceiling top and remove the FFU casing, could change original high efficiency particulate air filter then; Can't stand in and change filter in the dust free room, or can't guarantee its air-tightness in indoor replacing, last changing type highly effective air outlet is changed the ceiling headroom is required height; At least leave the space that the workman carries the filter climbing; And often be covered with air-conditioning duct in this space, distribution pipe, airduct; Cleaning equipment etc.; And when changing filter, have many tops dust stratification and directly fall into dust free room, cause auxiliary air to pollute than being easier to dustfree environment or to the production equipment that cleanliness factor is had relatively high expectations, it is big that this technology is changed difficulty; The replacing time is long, and labour cost or enterprises production efficiency are all had direct or indirect influence.

Under the formula of changing then be to improve in the casing highly, do rib at box house, be aided with screw mandrel and fastener and add the fixed by nut high efficiency particulate air filter; Do diffuser plate in tuyere bottom again and be fixed on the base, the lifting of casing must be made 4 rhizoid bars at the smallpox top, is aided with the top that turnbuckle is pulled in casing below; The construction trouble, cost is high, and following changing type highly effective air outlet requires top of building that the function that can make expansion hang spring bar must be arranged; Some steel-structure factory buildings just can not satisfy this requirement; And existing usefulness tightens fastener and guarantees that the way of sealing causes air-tightness bad in actual use easily, moreover cost is higher, and using portion changes little to some extent on market.

The utility model content:

The purpose of the utility model provides novel changing type highly effective air outlet down, and difficulty was big when it overcame prior art replacing consumptive material, and inefficient defective provides a kind of casing to need not lifting, from following replacing filter, can effectively reduce cost, and guarantees air-tightness.

In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it is made up of efficient filter screen 1, sealing strip 2, efficient air outlet casing 3, Embeded nut 4, fixed screw 5; The both sides of efficient filter screen 1 are respectively arranged with sealing strip 2, and the upper end of efficient filter screen 1 is provided with efficient air outlet casing 3, and the two ends, bottom of efficient air outlet casing 3 are respectively arranged with Embeded nut 4, and are fixedly connected with efficient filter screen 1 through fixed screw 5.

It is difficult that the utility model has solved existing efficient air outlet replacing filter; And from the very difficult difficult problem that guarantees the sealing of filter of following replacing; And more existing changing type highly effective air outlet down significantly reduces on production cost; And solved the lifting problem, and can effectively save manual work, the minimizing of cost is beneficial to the popularization in market.

Difficulty was big when the utility model overcame prior art replacing consumptive material, and inefficient defective provides a kind of casing to need not lifting, from following replacing filter, can effectively reduce cost, and guarantees air-tightness.

Description of drawings:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the A portion enlarged drawing of Fig. 1.

The specific embodiment:

With reference to Fig. 1, Fig. 2, this specific embodiment adopts following technical scheme: it is made up of efficient filter screen 1, sealing strip 2, efficient air outlet casing 3, Embeded nut 4, fixed screw 5; The both sides of efficient filter screen 1 are respectively arranged with sealing strip 2, and the upper end of efficient filter screen 1 is provided with efficient air outlet casing 3, and the two ends, bottom of efficient air outlet casing 3 are respectively arranged with Embeded nut 4, and are fixedly connected with efficient filter screen 1 through fixed screw 5.

The installation steps of this specific embodiment are: a, panel beating welding: after adopting certain thickness steel plate to tear material open by the customer requirement size, and through shear, bending; Common production technologies such as welding are produced efficient air outlet casing crude green body; This thick embryo need be carried out positioning strip and fixed edge, and the rib of 25mm is left in the positioning strip bottom, and the rib welding needs smooth; Integral body requires outward appearance clean and tidy, firm welding; B, tank surface handle: carry out the surface treatment of casing according to the difference of casing material, make like cold-rolled steel sheet, then will do the surface electrostatic painting baking vanish and handle, stainless steel then will be carried out corresponding atomizing in this way, wire drawing or surface protection etc.; C, nut fixed point is pre-buried: it is pre-buried on the rib of bottom half, to carry out the nut fixed point, and this pre-buried point is corresponding with screw hole on the lockable filter; D, check assembly: be finished product after an efficient air outlet casing is joined a lockable filter and the check of screw accessory specification.

It is difficult that this specific embodiment has solved existing efficient air outlet replacing filter; And from the very difficult difficult problem that guarantees the sealing of filter of following replacing; And more existing changing type highly effective air outlet down significantly reduces on production cost; And solved the lifting problem, and can effectively save manual work, the minimizing of cost is beneficial to the popularization in market.

Difficulty was big when this specific embodiment overcame prior art replacing consumptive material, and inefficient defective provides a kind of casing to need not lifting, from following replacing filter, can effectively reduce cost, and guarantees air-tightness.
