The sealing device comprises a kettle body and a kettle cover, wherein a flange is arranged on the kettle body at the position in contact with the kettle cover, an annular groove is arranged on the flange, an annular bulge is arranged on the kettle cover at the position in contact with the kettle body, the annular groove is internally provided with a filling layer filled with a high-temperature-resistant sealing medium, the annular bulge tightly presses the filling layer and is matched with the annular groove, and a fixing structure is arranged between the kettle cover and the kettle body. The sealing structure disclosed by the utility model has the advantages of simple structure, low cost and excellent sealing performance, the sealing problem of the dry distillation kettle is solved and thus the yield of carbon is increased, flue gas does not leak and is completely supplied to combustion, and the production cost is saved.

Description

A kind of sealed structure of high temperature carbonization retort

Technical field

The utility model relates to bamboo charcoal production unit technical field, specifically a kind of sealed structure of high temperature carbonization retort.

Background technology

Domestic to a little less than the Study of Thin of the sintering technology of bamboo charcoal, bamboo charcoal is produced and is also rested on the technological phase that utilizes earth kiln to fire.Earth kiln method is because state of the art is low, and the material of putting up a kiln mostly is common masonry, without technology content, the structure properties of kiln is poor, ubiquity stopping property is poor, and the serious and technological temperature of bamboo charcoal oxidative phenomena mainly relies on " observing nasil " defect such as to grasp, so that the bamboo charcoal inferior quality of firing.And retort production is a kind of carbonizing production of can producing simultaneously, produce the production unit of biomass extract, tar and combustible gas.

Adopt dry distillation to there is obvious advantage, the one, the degree of oxidation of making charcoal is low, char yield rate is high, has improved unit output; The 2nd, can realize self-supporting function; The 3rd, saving carbonization time that can be a large amount of.Retort reactor has determined performance and the yield of bamboo charcoal, and the resistance to air loss of retort has determined the productive rate of bamboo charcoal.Good SLD, can effectively control the oxidation of bamboo charcoal, reduces the degree of oxidation of bamboo charcoal, improves the yield of bamboo charcoal.

Summary of the invention

The utility model is not enough for prior art, and a kind of sealed structure that simultaneously has good stopping property concurrently simple in structure, low-cost is provided, and solves the sealing problem of retort, thereby raising carbon yield, assurance combustion gas is not revealed, and supplies with the object of burning completely, saves production cost.

In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of sealed structure of high temperature carbonization retort, comprise kettle and kettle cover, on described kettle, be provided with flange with kettle cover contact position, on described flange, be provided with ring groove, described kettle cover and described kettle contact position are provided with annular protrusion, in described ring groove, be provided with the packing layer that refractory seals Filled Dielectrics forms, described annular protrusion compresses described packing layer and coordinates with described ring groove, between described kettle cover and described kettle, is provided with fixed sturcture.

In technique scheme, preferred, described packing layer is quartz sand layer.

In technique scheme, preferred, described packing layer is sandy soil layer.

In technique scheme, preferred, described packing layer depth of cracking closure is 1/2 to 2/3 of the described ring groove degree of depth.

Described fixed sturcture is that described kettle adopts bolt to be fixedly connected with described kettle cover.

The utility model compared with prior art, has following beneficial effect: the utility model good stopping property, sealing problem of solution retort of simultaneously having concurrently simple in structure, low-cost, thereby raising carbon yield, assurance combustion gas is not revealed, and supplies with the object of burning completely, saves production cost.

Accompanying drawing explanation

Fig. 1 is the sectional structure schematic diagram of the utility model embodiment.

Fig. 2 is the partial enlarged drawing of Fig. 1.

the concrete structure of implementing

Below in conjunction with accompanying drawing and the concrete structure of implementing, the utility model is described in further detail: referring to Fig. 1 to Fig. 2, a kind of sealed structure of high temperature carbonization retort, comprise kettle 1 and kettle cover 2, on described kettle 1, be provided with flange 3 with kettle cover 2 contact positions, on described flange 3, be provided with ring groove 4, described kettle cover 2 is provided with annular protrusion 5 with described kettle 1 contact position, in described ring groove 4, be provided with the packing layer 6 that refractory seals Filled Dielectrics forms, described annular protrusion 5 compresses described packing layer 6 and coordinates with described ring groove 4, between described kettle cover 2 and described kettle 1, be provided with fixed sturcture 7.Described packing layer 6 is quartz sand layer or sandy soil layer, and described packing layer 6 depth of cracking closures are 1/2 to 2/3 of described ring groove 4 degree of depth, and in the present embodiment, described fixed sturcture 7 is that described kettle 1 adopts bolts to be fixedly connected with described kettle cover 2.

With adopting the retort of sealing structure, test, experimental data is as follows: test 1: take thick bamboo tube as raw material, feed and fire bamboo charcoal into carrying out industrial production in retort, retort volume is about 3.2m3, each retort charging is about 500kg, at high temperature carries out destructive distillation and fires bamboo charcoal.The combustion gas at high temperature producing, through gas leakage test, without gas leak phenomenon, it produces gas quantity can be supplied in self charing use completely, and its carbonization temperature can reach 500 ℃, and bamboo charcoal productive rate reaches 22%.

Test 2: take bamboo chip as raw material, feed and fire bamboo charcoal into carrying out industrial production in retort, retort volume is about 3.2m3, each retort charging is about 550kg, at high temperature carries out destructive distillation and fires bamboo charcoal.The combustion gas at high temperature producing, through gas leakage test, without gas leak phenomenon, it produces gas quantity can be supplied in self charing use completely, and its carbonization temperature can reach 500 ℃, and bamboo charcoal productive rate reaches 25%.

Test 3: take bamboo wood scrap material as raw material, feed and fire bamboo charcoal into carrying out industrial production in retort, retort volume is about 3.2m3, each retort charging is about 600kg, at high temperature carries out destructive distillation and fires bamboo charcoal.The combustion gas at high temperature producing, through gas leakage test, without gas leak phenomenon, it produces gas quantity can be supplied in self charing use completely, and its carbonization temperature can reach 550 ℃, and bamboo charcoal productive rate reaches 26%.

And fire bamboo charcoal because the air capacity entering is too large by traditional earth kiln method, the productive rate of bamboo charcoal is generally below 20%, adopt this sealed structure to promote greatly the productive rate of bamboo charcoal, and this sealed structure is simple in structure, with low cost.
