Description

Technical Field

[0001] The invention relates to the technical field of heat insulation and cooling of kilns, and in particular to a kiln with a heat insulation and cooling mechanism. Background Art

[0002] A kiln is a furnace used to fire ceramics and sculptures or to fuse enamel to the surface of metal objects. It is usually made of bricks and stones and can be made into various sizes according to needs. It can be operated by combustible gas, oil or electricity. When the kiln is in use, in order to ensure heat, insulation boards will be installed around the inner wall of the kiln to prevent heat loss, and an exhaust structure will also be provided to discharge residual heat inside the kiln after the kiln finishes working, to prevent personal injury when the kiln is opened.

[0003] After searching:

[0004] A furnace cooling device, with publication number CN212778679U. Before use, water in a water tank is pumped into a water cooling chamber by a water pump to cool the inner furnace. By filling the water cooling chamber with water and providing a heat insulating film on the outer wall of the inner furnace, the heat generated during combustion in the inner furnace can be effectively isolated to prevent the heat from being dissipated to the outer furnace. When the water temperature in the water cooling chamber is too high, the water pump is controlled to continue to supply water to the inside of the water cooling chamber so that the water is discharged from the curved pipe. At the same time, the fan blades rotate to cool the water in the curved pipe. The cooled water is then supplied to the inside of the water tank from the water inlet pipe.

[0005] However, in the above-mentioned prior art, the inner furnace is arranged in the outer furnace, the cold water chamber is arranged between the inner furnace and the outer furnace, and the heat insulation film is arranged on the outer wall of the inner furnace, that is, between the inner furnace and the cold water chamber. Therefore, when the cold water chamber is filled with cold water, since the heat insulation film plays a role in preventing heat loss, the presence of the heat insulation film will hinder the heat in the inner furnace from entering the cold water chamber, thereby affecting the cooling effect of the inner furnace.

[0006] Another example is a kiln cooling device, with publication number CN220771913U, comprising: a kiln body, a cooling air intake assembly, the cooling air intake assembly being arranged at the top of the furnace of the kiln body, and one end of which extends out of the kiln body; a heat exchanger, the heat exchanger being arranged on the outside of the kiln body, and one end of which extends out from the cooling air intake assembly, and one end of the kiln body being connected to the cooling air intake assembly comprising: a cooling air intake pipe, a first part of the cooling air intake pipe being arranged at the top of the furnace, and a second part extending out of the kiln body, and a plurality of cooling air intake holes being evenly arranged at the bottom of the first part; a first connecting pipe, an air intake collecting pipe, the top end of the first connecting pipe being connected to the second part, and the bottom end being connected to the top end of the air intake collecting pipe.

[0007] However, in the above-mentioned prior art, the first part of the cooling air inlet pipe is arranged at the top of the furnace. Therefore, when the kiln is in use, even if the cooling air inlet pipe is not working, a small amount of heat in the kiln will still heat the cooling air inlet pipe itself. Because the second part of the cooling air inlet pipe extends out of the kiln, the heat in the kiln will be lost to the outside of the kiln in a continuous and small amount, thus affecting the thermal insulation effect of the kiln.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] See also Figure 1-Figure 14 Embodiment 1: This embodiment provides a technical solution: a kiln with a heat-insulating cooling mechanism, comprising a furnace body 1, wherein the furnace body 1 is provided with a heat-insulating cooling mechanism consisting of a heat-insulating part and a cooling part, wherein the cooling part is provided with a switch mechanism for controlling the switch state of the heat-insulating part, and a regulating mechanism for controlling the opening and closing amount and the opening and closing position of the heat-insulating part in the heat-insulating cooling mechanism, and the regulating mechanism includes a transmission mechanism for the operation of the switch mechanism.

[0045] The cooling part includes an air extraction cavity 2 opened in the side wall of the furnace body 1, the heat insulation part includes a partition 4 installed between the air extraction cavity 2 and the inner wall of the furnace body 1, and the heat insulation part also includes a plurality of groups of heat insulation boards 5 distributed in a linear array and located in the air extraction cavity 2, and each group of heat insulation boards 5 is provided with two and symmetrically arranged;

[0046] Specifically, the opening and closing amount in the above description refers to the opening angle of the insulation board 5 in the insulation part, and the opening and closing position refers to controlling the insulation board 5 at a specific position to rotate and open. The top of the exhaust chamber 2 is connected to the ventilation pipe. When the exhaust chamber 2 is connected to the inside of the furnace body 1, the ventilation pipe is used to inject cold air and extract hot air, so as to achieve cooling in the furnace body 1. When heat preservation and heat insulation, it is only necessary to use several insulation boards 5 to be arranged side by side and fit the surface of the partition 4, and install a whole piece of insulation board 5 or insulation material on the other inner wall of the furnace body 1 according to the existing insulation method, so as to achieve insulation in the furnace body 1.

[0047] Embodiment 2: Different from the above embodiment, this embodiment also discloses:

[0048] The switch mechanism includes a swing arm 7 rotatably mounted on the bottom of the air pumping chamber 2 and corresponding to a plurality of heat insulation boards 5, the left end of the swing arm 7 is fixed to the bottom edge of the heat insulation board 5, and a spring 8 is connected between the right end and the bottom of the air pumping chamber 2, the two swing arms 7 corresponding to each group of heat insulation boards 5 are symmetrically arranged, and the opposite surfaces of the right ends of the two swing arms 7 are connected to traction ropes 9, and the two traction ropes 9 are symmetrically arranged, and the switch mechanism also includes two rope threading blocks 10 fixed to the bottom of the air pumping chamber 2 and arranged at the traction rope 9, the traction rope 9 passes through the two rope threading blocks 10 at corresponding positions, and each traction rope 9 is L-shaped between the right end of the swing arm 7 and the two rope threading blocks 10, and the free ends of the two traction ropes 9 corresponding to each group of heat insulation boards 5 are connected to connecting handles 11;

[0049] Reference Fig.10 The spring 8 is in a relaxed state under normal conditions, and the spring 8 is used to ensure that the swing arm 7 connected thereto does not swing, thereby achieving that the heat insulation board 5 installed at the left end of the swing arm 7 remains as Figure 3 The state shown, that is, the hollow part of the partition 4 is sealed by using a plurality of arranged heat insulation boards 5 to realize the isolation of the interior of the furnace body 1 from the exhaust chamber 2, and by installing heat insulation materials on other inner walls of the furnace body 1, it is ensured that the heat of the furnace body 1 will not be transferred to the exhaust chamber 2 through other media during operation, so as to ensure that the heat in the furnace body 1 will not be lost. When cooling is required, it is only necessary to lift the connecting handle 11 in the vertical direction, and use the connecting handle 11 to pull the traction rope 9 to move along the L-shaped route under the restriction of the two rope threading blocks 10, that is, the traction rope 9 pulls the right end of the swing arm 7 to drive the spring 8 to stretch and move elastically, and when the right ends of the two swing arms 7 at each group of heat insulation boards 5 are close to each other, under the action of the lever principle, the left end of the swing arm 7 drives the heat insulation board 5 to rotate, so that the heat insulation board 5 does not fit the partition 4, so that the residual heat in the furnace body 1 can enter the exhaust chamber 2 along the opened heat insulation board 5 to achieve cooling.

[0050] The switch mechanism also includes a lifting bar 6 plugged into the wall of one side of the air extraction chamber 2, a horizontal slide groove 13 is provided on the side of the lifting bar 6, and a hook 12 for sleeved on the connecting handle 11 is slidably connected in the horizontal slide groove 13;

[0051] Specifically, in order to realize the movement of the connecting handle 11, the lifting bar 6 is used to rise along the inner wall of the exhaust chamber 2, and the hook 12 is driven to rise under the restriction of the horizontal slide groove 13, and the hook 12 is used to engage with the connecting handle 11 to realize the rising of the connecting handle 11. When the hook 12 slides along the horizontal slide groove 13 until it is disengaged from the connecting handle 11, the connecting handle 11 will not rise with the rising of the hook 12, thereby ensuring that the insulation board 5 of this part will not rotate open. By staggering the hook 12 and the connecting handle 11 at different positions, it is convenient to realize that when the lifting bar 6 rises, the insulation boards 5 at different positions and numbers are rotated and opened, which is convenient for controlling the cooling speed, or according to the placement of the objects in the furnace body 1, it is selected whether the airflow during cooling passes through the objects.

[0052] Embodiment 3: The regulating mechanism includes a connecting plate 16 fixed to one side of the lifting bar 6, and a plurality of through shafts 17 are arranged on the front edge of the connecting plate 16, one end of the through shaft 17 extends to the back of the connecting plate 16 and the back of the connecting plate 16 is also connected to a spring 8 for being sleeved on the through shaft 17, one end of the spring 8 on the connecting plate 16 is fixed to the through shaft 17, and the extending end of the through shaft 17 extends outward and is fixedly connected to a connecting rod 15, the number of the plurality of connecting rods 15 is equal to the number of the plurality of hooks 12 and is divided into two rows, and the plurality of The connecting rods 15 correspond to the hooks 12 one by one, and any connecting rod 15 extends outwardly to be connected to the corresponding hook 12 with a connecting arm 14. The regulating mechanism also includes a fixing block 24 fixed on the front of the connecting disk 16 and arranged near each through-axis 17. An elastic block 25 is inserted and inserted into the fixing block 24 through a spring rod. One side of the elastic block 25 penetrates the fixing block 24 and extends outwardly to be fixedly connected to a connecting frame 26. The connecting frame 26 is opened on one side facing the connecting disk 16 and an inclined portion 27 is arranged on one side of the inner bottom.

[0053] Specific: such as Fig.11As shown, a limit frame is vertically arranged at one end of the through shaft 17 located on the front of the connecting disk 16, and a spring 8 is installed on the other end of the through shaft 17 and the back of the connecting disk 16. Therefore, under normal circumstances, the spring 8 on the back of the connecting disk 16 is in a relaxed state. Under the connection action of the connecting rod 15 and the connecting arm 14, the through shaft 17 is rigidly connected with the corresponding hook 12. Therefore, by fixing the position of the through shaft 17, it is ensured that the hook 12 and the connecting handle 11 are in a plug-in relationship, that is, when the lifting bar 6 rises, the insulation board 5 will rotate open, and when the rectangular part of the through shaft 17 is pushed forward, the spring 8 on the corresponding air surface will be elastically compressed, and then under the connection action of the connecting rod 15 and the connecting arm 14, the hook 12 is separated from the connecting handle 11 until the inner wall of the limit frame is clamped on the fixed block 24, and continues to move until it contacts the inclined surface of the elastic block 25, forcing the elastic block 25 to overcome the thrust of the spring rod. The spring 27 is provided to prevent the through-axis 17 from moving under the elastic extension and resetting action of the spring 8 on its surface. The role of the inclined portion 27 is to make the inclined portion 27 drive the connecting frame 26 away from the fixed block 24 through the inclined surface of the inclined portion 27, so that the elastic block 25 can overcome the thrust of the spring rod again and descend to the position misaligned with the limit frame under the action of the fixed connection, so as to realize the resetting of the through-axis 17. That is, when the lifting strip 6 is located at the bottom of the air extraction chamber 2, the disengaged hook 12 can be re-contacted with the connecting handle 11. In addition, the elastic block 25 in this embodiment is a right-angled triangle block, and the inclined surface faces the connecting disk 16. The bottom plane part is embedded in the surface of the fixed block 24 and is connected to the fixed block 24 through the spring rod.

[0054] Embodiment 4: The transmission mechanism includes a rack 3 distributed on the side of the lifting bar 6 and vertically fixed to the inner wall of the exhaust chamber 2, and a spur gear 19 that penetrates and rotates in the lifting bar 6. The spur gear 19 is meshed with the rack 3. One end of the spur gear 19 is fixedly connected to a worm gear 18. The side of the lifting bar 6 is also rotatably connected to a worm 22 that is meshed with the worm gear 18. The bottom end of the worm 22 extends in a block shape and is plugged with a plug-in gear ring 21.

[0055] Specifically, by adjusting the upper and lower positions of the plug-in gear ring 21 and applying force to the plug-in gear ring 21 to rotate it, because the plug-in gear ring 21 is plugged into the block-shaped part of the worm 22, the plug-in gear ring 21 will drive the worm 22 to rotate when it rotates, thereby realizing the rotation of the worm wheel 18 meshing with the worm 22, and the spur gear 19 can be rotated under the action of fixing. By utilizing the through-rotating connection and the meshing connection, the spur gear 19 can be rotated relative to the lifting bar 6 and roll on the surface of the rack 3, driving the lifting bar 6 is lifted and lowered under the condition of being plugged in with the inside of the air extraction chamber 2, and the unidirectionality of the transmission of the worm wheel 18 and the worm 22 is utilized so that the plug-in gear ring 21 rotates without the action of external force, and the lifting bar 6 will not fall. The principle is that when the lifting bar 6 falls under the action of gravity, the spur gear 19 will rotate on the rack 3, thereby driving the worm wheel 18 to rotate. Since the worm wheel 18 cannot drive the worm 22 to rotate, the worm wheel 18 will not rotate. Reverse deduction shows that the spur gear 19 will not rotate either, so the lifting bar 6 will not fall under the action of gravity.

[0056] The transmission mechanism also includes a first transmission mechanism, a second transmission mechanism and a driving mechanism. The first transmission mechanism includes a pin shaft 32 which is installed through the central axis of the connecting disk 16 and is damped. The pin shaft 32 is located at the back of the connecting disk 16 and is fixedly connected to the driven gear ring 31. The pin shaft 32 is located at the front of the connecting disk 16 and is plugged with a T-shaped plate 39. The T-shaped plate 39 is parallel to the front of the connecting disk 16 and is sleeved with a plug shell 37. A convex plate 49 for contacting the elastic block 25 and the inclined portion 27 is fixedly connected to the top edge of one side of the plug shell 37. A longitudinal screw rod 38 and a transverse screw rod 33 are respectively threaded through the outer wall of the plug shell 37 near the top edge and the end face of the pin shaft 32. One end of the longitudinal screw rod 38 and the transverse screw rod 33 are both rotatably connected to the T-shaped plate 39 and fixedly connected to the end bevel gear 40.

[0057] Specifically, when a force is applied to the end bevel gear 40 on the end face of the longitudinal screw rod 38 to make it rotate, the longitudinal screw rod 38 will be driven to rotate, and then the plug housing 37 will drive the convex plate 49 on its surface to move relative to the T-plate 39, so that the convex plate 49 can be moved up and down to align with the limit frame or the connecting frame 26 at one end of the through-shaft 17, and then the end bevel gear 40 on the transverse screw rod 33 is applied with power to rotate it, so that the transverse screw rod 33 can be rotated, and the horizontal part of the T-plate 39 is connected with the pin 32 to prevent the T-plate 39 from rotating, that is, the T-plate 39 moves relative to the pin 32 under the rotation of the transverse screw rod 33, so that the plug housing 37 can drive the convex plate 49 to move with the movement of the T-plate 39, and when the convex plate 49 is aligned with the limit frame at one end of the through-shaft 17 When the protruding plate 49 is aligned with the connecting frame 26, the protruding plate 49 is moved to contact the inclined surface 27 inside it to realize the movement of the connecting frame 26. In addition, the surface of the pin shaft 32 in this scheme forms a damping fit with the connecting disk 16 by installing a rubber pad, so as to ensure that the pin shaft 32 will not rotate and swing due to the inclination of the plug shell 37 when no rotational force is applied, thereby ensuring that the protruding plate 49 will not shift or misalign when the up and down, front and back positions are adjusted. By applying a rotational force to the driven gear ring 31, when the applied force is greater than the friction between the pin shaft 32 and the connecting disk 16, the pin shaft 32 will be driven to rotate, thereby realizing the rotation and movement of the protruding plate 49 to the next through-shaft 17 that needs to be adjusted.

[0062] The method of use and working principle of the device are as follows: the object is placed on the object rack, and slides along the known slide rail in the furnace body 1 into the furnace body 1, the door panel of the furnace body 1 is closed, and the temperature in the furnace body 1 is raised by using a known heating method such as electric heating or steam heating to process the object. During the heating process, a plurality of heat insulation boards 5 are unfolded and attached to the surface of the partition board 4 to prevent the heat in the furnace body 1 from entering the exhaust cavity 2. After the processing is completed, when all the heat insulation boards 5 need to be opened, keep the temperature as shown in the figure. Figure 1In the state shown, that is, at this time, the convex plate 49 does not interfere with the position of the fixed block 24 and the through-shaft 17, and the plug-in gear ring 21 is meshed with the horizontal gear 35 by the electric push rod 20 rising, and then the electric telescopic rod 28 on the back of the connecting plate 16 is contracted to realize that the driving gear 30 on the rear main shaft of the dual-axis motor 29 is meshed with the driven gear ring 31, so that the dual-axis motor 29 can drive the driven gear ring 31 to rotate, and then the pin shaft 32 is driven, and then the rotating gear ring 23 is rotated, and the rotating gear ring 23 drives the longitudinal gear 34 to rotate, and under the meshing connection of the two side bevel gears 36, the horizontal gear 35 is rotated, and the meshing connected plug-in gear ring 21 drives the worm 22 to rotate, and then the worm wheel 18 meshing with the worm 22 is rotated, and the spur gear 19 can be rotated under the fixed action, and the spur gear 19 is realized. The lifting bar 6 rotates relative to the lifting bar 6 and rolls on the surface of the rack 3, driving the lifting bar 6 to rise under the condition of being plugged into the inside of the air extraction chamber 2, and the lifting bar 6 is used to rise along the inner wall of the air extraction chamber 2, and the hook 12 is driven to rise under the restriction of the horizontal slide groove 13, and the hook 12 is used to engage with the connecting handle 11 to realize the rising of the connecting handle 11, and the connecting handle 11 is used to pull the traction rope 9 to move along the L-shaped route under the restriction of the two rope threading blocks 10, that is, the traction rope 9 pulls the right end of the swing arm 7 to drive the spring 8 to stretch and move elastically, and when the right ends of the two swing arms 7 at each group of heat insulation boards 5 are close to each other, under the action of the lever principle, the left end of the swing arm 7 drives the heat insulation board 5 to rotate, so that the heat insulation board 5 does not fit the partition 4, so that the residual heat in the furnace body 1 can enter the air extraction chamber 2 along the fully opened heat insulation boards 5 to achieve cooling;

[0063] When it is necessary to control the direction or speed of the air flow during cooling, it is only necessary to rotate the pin shaft 32 to realize the T-plate 39 to drive the plug shell 37 and the convex plate 49 on its surface to move to the corresponding through-shaft 17 when the plug-in gear ring 21 is not engaged with the horizontal gear 35. The driving mechanism cooperates with the first transmission mechanism to first adjust the position of the convex plate 49 to align with the limit frame at the end of the through-shaft 17, and then use the T-plate 39 to drive the plug shell 37 to move, so that the convex plate 49 pushes the limit frame to contact and overlap with the vertical surface of one side of the elastic block 25, so that the hook 12 connected to the through-shaft 17 at this position can be disengaged from the corresponding connecting handle 11, and then the convex plate 49 is reset. By repeating the above process, the heat insulation board 5 at a specific position can be controlled not to rotate and open with the rise of the lifting bar 6.
