Abstract

Disclosed is an enamel connecting tank for the wastewater treatment, which is characterized in that each layers of the tank body, which consist of the tank body, is made of the connection and installation of a plurality of enamel thin steel plates. Wherein the transverse edge of each of the enamel steel plates is provided with a correspondingly connecting hole and the connecting hole are fixedly connected by bolts. The connecting part of the two overlapped plates is embedded with soft sealing glue layer and the upper and lower edges of each enamel steel plate are pressed with an outward curving edge and are fixedly connected by bolts. The connecting surface between the plates of the connecting parts is also coated with a soft sealing glue layer. The utility model enables the 2-4mm enamel steel plates to be constructed into a reaction tank with the volume of 100-5000m# +<3> with an acid and alkali resistance, a corrosion resistance, an impact resistance, a wear resistance and a short construction period, a convenient capacity expansion, a small weight and a low production cost. Compared with the reinforced concrete and common welded steel structure the utility model can save 30-50% of the construction cost per square meter and the utility model has a long service life. The utility model is not only fit for the wastewater treatment construction of small town but also fit for the wide application to various tank body type storing equipments.

Description

The enamel assembly unit jar that is used for sewage disposal

The utility model relates to the tun manufacturing technology, particularly a kind of enamel assembly unit (container) jar that is used for the town sewage processing.

Enter 21st century, the mankind are faced with the in short supply of fearful pollution and water resources, and along with the aggravation that water pollutes, China has been one of the shortest country of water resources per capita in the world.For the water pollution control target that realizes that China " 15 ", Eleventh Five-Year Plan are formulated, the sewage that need produce the industrial and agricultural production life of the many middle samll cities and towns of wide point is handled.But mostly used various reaction vessels or retort are to construct with Steel Concrete and form in traditional sewage disposal device, or make with the Plate Steel welding, have the construction costs height, can't tear open and drive resettlement, Corrosion Protection is poor, and the maintenance difficulty is big, work-ing life is short, shortcomings such as running cost height.Administer engineering in the face of numerous medium and small town sewages from now on, how saving construction investment and reduce running cost will be the key of carrying out water prevention and cure of pollution smoothly.

Characteristics (cost is lower than the cost of concrete and ordinary steel structure) such as the purpose of this utility model provides a kind of enamel assembly unit (container) that is used for sewage disposal jar, it has short construction period, cost is low, corrosion-resistant, intensity is good, quality is high, easy to maintenance, long service life.

The utility model is realized with following technical scheme: it is by the can body that constitutes the multilayer tank body, top ends of cans, the jar end, opening for feed, discharge outlet, the pressure exhaust valve (safety valve) that overflows is formed, it is characterized in that every layer of tank body is assembled by slices plating enamel steel sheet overlap joint, wherein at the widthwise edge of every block of adjacent enameling sheet along all being provided with corresponding connecting hole and connecting with bolted, all inlay (coating) between equitant two plates in its junction soft sealant layer is arranged, and the lower edge all is pressed into outside crimping (can play the stiffening web effect) on every block of adjacent enameling sheet, on these crimpings, all be provided with corresponding connecting hole and connect, between the plate of junction and plate interface, also inlay and be coated with soft sealant layer with bolted.

Shell structure principle in the plastic working of the utility model applied metal, the plating enameling sheet of 2-4mm only can be built up volume by specific equipment is 100-5000m ³Retort (device), not only has antiacid, alkali, corrosion-resistant, the surface has stronger shock resistance, abrasion resistance, also has short construction period, dilatation is convenient, dismounting resettlement easily, and is easy to maintenance, low from heavy and light, cost, construction cost per square meter with volume reactor (jar) is saved 30-50% than the construction cost per square meter of Steel Concrete or common weldable steel (plate) structure, reaches work-ing life more than 20 years.The utility model not only can be applicable to samll cities and towns' waste water treatment project, and various water supply and sewage work also can extensively be used as all kinds of tank body formula storage facilities.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the structural representation of a kind of tank body of the present utility model.

Fig. 2 and Fig. 3 are respectively the A-A of Fig. 1, the cross-sectional view at B-B direction position.

Fig. 4 is the structural representation of top ends of cans.

Fig. 5 and Fig. 6 are respectively the C-C of Fig. 4, the cross-sectional view at D-D direction position.

Wherein: 1-tank body (can body shell), 2-(flexibility) enamel steel sheet (sheet material), 3-opening for feed, 4-top cover, 5-vent valve (safety valve), 6-go on foot ladder, discharge outlet at the bottom of the 7-jar, the soft sealant layer of 8-, 9-retaining bolt, 10-tension force pad, 11-nut, 12-crimping, 13-constitutes the top cover fan-shaped enameling sheet (sheet material) at (or jar end), the 14-stiffening web, 15-O-ring seal, 16-tank deck disk (substrate)

With reference to accompanying drawing as can be known, the utility model also has following technical characterictic when entity design is made:

One, described top ends of cans 4 is all made with fan-shaped enameling sheet 12 with pot bottom and is overlapped mutually and with the structure that bolted is connected, all be provided with connecting hole and use bolted between equitant two plates in its junction.

Two, described bolt is to adopt retaining bolt 9, and the pad that cooperates with nut 11 is a tension force pad 10.

Three, all can be provided with multiple tracks stiffening web 13 at tank body can body and top ends of cans 4, stiffening web can set up or be fixed on the bolt fasteners of junction between plate.
