Technical Field

[0001] The invention relates to the technical field of ceramic filler production, in particular to a ceramic filler sintering furnace. Background Art

[0002] Ceramic fillers are mainly made of two kinds of clay with different properties, namely pottery clay and porcelain clay. They are made through a process of batching, forming, drying and sintering. They are an industrial material with excellent acid and heat resistance, corrosion resistance and price advantages.

[0021] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the arrangement of the furnace, heat transfer plate and heat conducting fins, the heat transfer plate and heat conducting fins can play a role in heat transfer, the furnace can be sealed, and the heating wire group does not need to be installed inside the furnace. The dust generated by the sintering of the ceramic filler inside the furnace will not affect the heat dissipation of the heating wire group, avoiding the dust from adhering to and accumulating on the surface of the heating wire group to cause damage to it.

[0022] 2. Through the setting of the insulation shell, the rotational assembly effect of the positioning ring A and the positioning ring B on the insulation shell is utilized, and the meshing matching between the spur gear and the inner gear ring is coordinated, so that the heating wire group loaded inside the insulation shell can be rotated in position, so that the heating wire group inside the insulation shell can act evenly on the outside of the furnace, so as to evenly transfer heat to the inside of the furnace.

[0023] 3. The surface area of ​​the furnace is increased by setting the heat transfer plate and the heat conducting fins. When the interior of the furnace is in a closed state, the efficiency of heat transfer from the heating wire group to the interior of the furnace through the heat transfer plate and the heat conducting fins is improved.

[0024] 4. Through the closed setting of the furnace chamber and the set between the insulation shell and the furnace chamber, a heat conduction zone can be formed between the insulation shell and the furnace chamber, and a sintering zone is formed inside the furnace chamber. The dust and dust between the two zones do not affect each other, avoiding excessive dust inside the furnace chamber from adhering to and accumulating on the surface of the heating wire group.

[0025] 5. Through the setting of external air inlet pipe and external exhaust pipe, the external cold air circulation equipment is used to cooperate with the heat transfer plate and the heat conduction fins to dissipate the heat of the heat conduction area. At the same time, the setting of internal air inlet pipe and internal exhaust pipe is used, and the external cold air circulation equipment is used to cool down the sintering area inside the furnace, thereby improving the efficiency of cooling and heat dissipation.

[0026] 6. By setting up the cleaning mechanism and utilizing the cooperation between the reciprocating screw A and the reciprocating screw B and the transverse seat respectively, the transverse frame can drive the support frame to reciprocate on the inner side of the heat-conducting fins, so that the scraper can clean the dust or dust attached to the surface of the heat-conducting fins, and the scraper can clean the stubborn accumulated dust on the surface of the heat transfer plate to avoid affecting the heat transfer of the heat transfer plate and the heat-conducting fins.

[0027] 7. Through the setting of the dust collecting mechanism, the dust inside the furnace is easily gathered and falls on the bottom of the furnace cavity. By utilizing the reciprocating motion of the cleaning mechanism and the opening and closing of the sealing plate by the cleaning mechanism, the dust can enter the dust collecting box to complete the collection operation, thereby avoiding excessive accumulation of dust inside the furnace and affecting the sintering process.

[0028] In summary, the present invention overcomes the shortcomings of the prior art, isolates and partitions the heat conduction zone and the sintering zone of the sintering furnace, prevents the dust generated by the sintering of ceramic fillers from adhering to and accumulating on the surface of the heating equipment to affect the heat transfer efficiency, and also prevents the dust from causing damage to the heating equipment. It has high social use value and application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] For other structures not described, refer to Example 1.

[0050] Working principle: In the present invention, the ceramic filler to be sintered is placed inside the rack 4, and then the furnace shell 1 is closed by closing the movable cover 101. At this time, the main sealing cover 1011 can seal the space formed by the heat preservation shell 2 and the furnace 3, and the auxiliary sealing cover 1012 can seal the internal space of the furnace 3. The above two spaces are not connected to each other. The outer air intake pipe 1013 and the outer exhaust pipe 1021 are connected to the external cold air circulation device, and the inner air intake pipe 211 and the inner exhaust pipe 212 are connected to the external cold air circulation device. After the sintering process is completed, the outer air intake pipe 1013 and the outer exhaust pipe 1021 can cool down the space formed by the heat preservation shell 2 and the furnace 3, and the inner air intake pipe 211 and the inner exhaust pipe 212 can cool down the inner space of the furnace 3; During the sintering process, the heating wire group 202 is turned on, and the driving motor 511 is turned on synchronously, so that the heating wire group 202 heats the inside of the heat preservation shell 2, and the heat transfer effect of the heat transfer plate 31 and the heat-conducting fins 311 causes the inside of the furnace 3 to be heated accordingly, so as to act on the ceramic filler to be sintered placed in the rack 4, so as to complete the sintering process of the ceramic filler. With the start of the driving motor 511, the driving gear 51 is rotated, so that the meshing match between the driving gear 51 and the driven gear 52 and the meshing match between the driven gear 52 and the synchronous gear 53 are achieved. The reciprocating screw rod A521 and the reciprocating screw rod B531 are matched to each other, so that the transverse moving seat 702 drives the transverse moving frame 701 to perform reciprocating transverse movement within the range of the heat-conducting fin 311, so that the scraper 707 can timely scrape off the dust attached to the surface of the heat-conducting fin 311, thereby preventing the dust from accumulating on the surface of the heat-conducting fin 311 and causing the heat transfer efficiency of the heat-conducting fin 311 to be reduced, and the scraper 706 can act on the surface of the heat transfer plate 31 to clean the surface of the heat transfer plate 31, thereby preventing the dust from accumulating on the surface of the heat transfer plate 31 and causing the heat transfer efficiency of the heat transfer plate 31 to be reduced; When the reciprocating screw rod B531 at the bottom of the furnace 3 rotates, the spur gear 532 can mesh with the inner gear ring 201, and under the action of the positioning ring A21 and the positioning ring B22, the heat preservation shell 2 rotates inside the furnace shell 1, so that the heat transfer of the heating wire group 202 to the furnace 3 is more uniform; When the transverse moving frame 701 is about to reach the end of the heat transfer fin 311, the push plate rod 705 on the inner bottom surface of the furnace 3 can contact the convex strip 8031, and follow the movement of the push plate rod 705, so that the sealing plate 803 can be inserted into the through groove 8021, so that the sealing plate 803 opens its seal on the top opening of the hanging box 801, so that the dust accumulated on the bottom of the push plate rod 705 and the top surface of the heat transfer plate 31 can be pushed into the hanging box 801, and the dust falls into the dust collecting box 8011 for collection. After the transverse moving frame 701 has reached the end of the heat transfer plate 31 and reciprocates, as the transverse moving frame 701 returns, the elastic deformation of the return spring 805 is restored, so that the sealing plate 803 covers and seals the top opening of the hanging box 801 again, so as to prevent the dust collected in the dust collecting box 8011 from being scattered due to the wind. After the ceramic filler is sintered, turn on the external cold air circulation device connected by the external air inlet pipe 1013 and the external exhaust pipe 1021, and turn on the external cold air circulation device connected by the internal air inlet pipe 211 and the internal exhaust pipe 212, and respectively cool the heat transfer zone formed by the insulation shell 2 and the furnace 3 and the sintering zone formed inside the furnace 3.
