Description

Ceramic abrasion resistant corrosion resistant refractory protection watt

Technical field

The utility model belongs to a kind of Industrial Boiler annex, and particularly a kind of ceramics on the pipe of electricity generation boiler four are prevented Anti-corrosion refractory protection watt is ground, the protection watt makes four pipes improve abrasion resistant corrosion resistant fire resistance, increased the service life.

Background technology

The boiler that power plant is generally used is provided with four pipes, i.e. water screen tube, economizer tube, superheater tube and reheater tube. In boiler operatiopn, once, in the presence of Secondary Air, flue gas is rushed at after furnace roof along with solid particle, and solid particle can be along pipe Wall constantly flows back downwards, in reflux course, and solid particle produces high speed thermal friction with tube wall, tube wall is produced abrasion, reduction The service life of four pipes.A kind of new ceramics wearing-resistant tile is disclosed in the Chinese patent of Patent No. 200720062207.7, should The technical scheme of patent has larger change than the technology using antifriction metal (AFM) alloy tile and surface spraying antifriction alloy protective layer Enter.This technology is further improved in the Chinese patent wearing-resistant tile of Patent No. 200820128389.9.But on This kind of product stated patented technology and used at present, still there is some shortcomings：The fixation of its watt of body fixture is insecure, easily occurs Unclamp and sealing-off phenomenon, cause coming off for wearing-resistant tile；One layer of glaze is fired in watt body surface face can increase cost, and effect and fail to understand It is aobvious；Particularly easily occur the radial deflection of wearing-resistant tile, influence using effect and service life etc..It is, therefore, desirable to provide entering one Improved technology is walked, the performance of the production device is further improved.

Utility model content

The purpose of this utility model is in order to solve the above-mentioned technical problem, to propose a kind of ceramic abrasion resistant corrosion resistant refractory protection Watt.Structure has further been tied in the protection watt perfect, realizes abrasion resistant corrosion resistant fire resisting effect more preferably, installs more firm, service life Longer effect.

The purpose of this utility model is achieved through the following technical solutions：

A kind of ceramic abrasion resistant corrosion resistant refractory protection watt, provided with a watt body, this watt of body is made up of wear-and corrosion-resistant refractory, watt body Radially circular arc, axially linear or circular arc；The upper and lower ends head of watt body, is respectively equipped with for close right between watt body up and down The mutually identical rabbet connect, is provided with open-work and metal fixing on watt body, and the open-work and metal fixing are used for general watt Body is fixed on the pipeline outer wall used；It is characterized in that：The open-work of described watt of body is one or several, and metal fixing is gold Category piece, wire, which one or both of are worked as, to be combined, and groove is provided between the fixing hole of described watt of external surface, the groove is with wearing The diameter for crossing the wire of fixing hole is matched, and a watt body is fixed on the pipeline outer wall used by wire.

The utility model is further improved and the additional project of implementation is：

The metal fixing is that sheet metal either sheet metal two ends add wire, and the sheet metal is by being fixed on open-work In rivet or screw be fixed on watt body, the smooth outer surface of the rivet or screw, the sheet metal or sheet metal add gold A watt body easily can be fixed on the pipeline outer wall used by category silk, and fixation is difficult for drop-off.

Described watt of body upper and lower ends are used for the mutually identical rabbet of watt body closed butt joint up and down and are provided with one or several The projection of mutual clamping and the groove being coincide with projection, the convex body and groove of the mutual clamping firmly connect neighbouring watt of body Connect, it is therefore prevented that the radial direction twisting dislocation of watt body each other.

Described watt of body upper and lower ends are used for the mutually identical rabbet of watt body closed butt joint up and down, one or number of setting The projection of individual mutual clamping and the structure of groove being coincide with projection are：Projection is set on interior concave edge at one end, in the other end Groove is set in inner raised edge.

Described watt of body upper and lower ends are used for the mutually identical rabbet of watt body closed butt joint up and down, one or number of setting The projection of individual mutual clamping and the structure of groove being coincide with projection are：Projection is set on the interior concave edge of watt body one end, it is same Groove is set on the outer flange at end, groove is set in the inner raised edge of the other end of watt body, with setting convex on the outer concave edge of one end Block, the bayonet socket that bumps are combined can prevent a watt body radial direction torsiversion malposition, can also prevent the outward-dipping of watt body.

Described watt of body upper and lower ends are used for the mutually identical rabbet of watt body closed butt joint up and down, one or number of setting The projection of individual mutual clamping and the structure of groove being coincide with projection are：It is respectively provided with watt concave edge of body one end and chimb convex Block, groove is respectively provided with the other end chimb and concave edge of watt body.

The axial left and right sides of described watt of body provided with inclined-plane from top to bottom, inclined-plane Shi Wati edges from inside to outside by Gradual change is thin, and the width on the inclined-plane is 0.2-10mm, and lower-upper length and watt body are isometric；The inclined-plane reduce the weight of watt body without Influence the properties of watt body.

The thickness of described watt of body, from middle two side to the left and right, is radially gradually thinned, and watt body interior thickness is 3mm- 10mm, edge thickness is 2mm-9mm；This is effectively alleviated the weight of watt body by the middle thickness change to longitudinal edge edge Amount, and because watt body is by the middle power that is hit to radial direction side, heat intensity gradually died down originally, so this watt of body The change of thickness has no effect on a watt body performance, greatly reduces production, transport, the cost and difficulty installed.

Advantage of the present utility model：

Fixed watt body is installed when the 1st, using to be more convenient, more firmly, mounting hole is smooth with watt body surface face, and performance is more preferable.

The clamping of adjacent watt of body is more firm when the 2nd, using, and effectively prevent the radial direction twisting dislocation between watt body.

3rd, watt body weight mitigates, and reduces production, transport, the cost and difficulty installed, improves benefit.
