[0019] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0020] The present application provides an oilstone sintering furnace, comprising: a sintering chamber 10, for providing a space for sintering oilstone; a transport assembly 20, for receiving oilstone and capable of transporting oilstone to the sintering chamber 10; an ignition assembly 30, which is arranged in the sintering chamber 10 and connected to a natural gas supply pipeline; when working, the transport assembly 20 can transport the oilstone to be sintered into the sintering chamber 10, the sintering chamber 10 is closed, and the ignition assembly 30 works and can sinter the oilstone by an open flame.

[0021] For details, please refer to Figure 1 In the illustrated embodiment, the sintering chamber 10 is configured in a dome form, and the top of the sintering chamber 10 is configured in an arc shape to facilitate heat collection and ensure effective volume. To increase production capacity, the volume of the sintering chamber 10 is not less than 5m³.

[0022] In order to facilitate the transfer of a large number of oilstones at one time, the transport assembly 20 includes a carrier and a transmission mechanism, wherein the carrier is used to load the oilstones, and the transmission mechanism is used to drive the carrier in and out of the sintering chamber 10. The carrier can be any structure that is convenient for placing the oilstones, such as a table, a rack, a frame, etc., and the transmission mechanism can be any structure that is convenient for moving the carrier, such as an overhead crane, a mobile trolley, a transmission platform, etc.

[0023] The ignition assembly 30 includes a gas nozzle, a solenoid valve and a spark plug. The gas nozzle is arranged in the sintering chamber 10 and connected to the natural gas supply pipeline. The solenoid valve is arranged on the natural gas supply pipeline. The working end of the spark plug is close to the spray hole of the gas nozzle. The transport assembly 20 delivers the oil stone into the sintering chamber 10. After the sintering chamber 10 is closed, the solenoid valve is opened, and the natural gas flows into the gas nozzle through the pipeline. At the same time, the spark plug is started, and the spark plug generates a high-voltage electric spark, which can ignite the natural gas sprayed through the spray hole of the gas nozzle, thereby generating an open flame in the sintering chamber 10.

[0024] In summary, through the oilstone sintering furnace provided by the present application, the sintering chamber 10 can quickly and reliably receive a batch of oilstones, thereby improving production capacity; since the oilstone transportation of the transport component 20 does not require direct participation of workers, the possibility of workers being injured due to high temperatures can be reduced; by using natural gas to achieve open flame sintering, the safety performance is high and it is not easy to have dangerous situations such as explosions. Since natural gas is a clean energy, there is no need to recycle and treat the exhaust gas to meet the emission standards, which is convenient and easy to use.

[0025] Optionally, the sintering chamber 10 is made of refractory bricks.

[0026] Refractory bricks are made of refractory materials (such as silica bricks, clay bricks, etc.). They not only have excellent heat resistance, but also have reliable load-bearing capacity, thermal shock resistance and slag resistance.

[0027] The sintering chamber 10 is constructed of refractory bricks, which can ensure the stability and safety of the sintering environment.

[0028] Optionally, the inner wall of the sintering chamber 10 is covered with an asbestos layer.

[0029] Specifically, after the sintering chamber 10 is closed, the walls of the sintering chamber 10 that are exposed to the open flame and used to surround the oilstone are all covered with an asbestos layer. Asbestos materials have high fire resistance and also have the functions of heat preservation, fire prevention, heat insulation, corrosion resistance, sound insulation, insulation, etc.

[0030] The asbestos layer can further improve the safety of the sintering chamber 10. In addition, after sintering, the ignition assembly 30 is turned off and the sintering chamber 10 is kept closed, and the residual temperature in the sintering chamber 10 can be maintained for a period of time, which is conducive to stabilizing and optimizing the densification effect of the oilstone.

[0031] Optionally, the oilstone sintering furnace provided in the present application further includes a steel frame 1, and the sintering chamber 10 is arranged on the steel frame 1; through the steel frame 1, the sintering chamber 10 is suspended above the ground.

[0032] For details, please refer to Figure 1 and Figure 2 In the illustrated embodiment, the steel frame 1 is arranged on the ground and has a certain height, and the sintering chamber 10 is arranged on the steel frame 1 and suspended above the ground. The steel frame 1 includes vertical legs and transverse reinforcing ribs. A plurality of vertical legs cooperate to support the sintering chamber 10, which is conducive to the sintering chamber 10 being stably suspended above the ground. At least one transverse reinforcing rib is arranged between any two adjacent vertical legs, and the transverse reinforcing ribs can further stabilize the vertical legs.

[0033] The sintering chamber 10 is suspended. On the one hand, when the sintering space of the sintering chamber 10 is matched with the transport component 20, after the transport component 20 sends the oil stone into the sintering chamber 10, the carrier loaded with the oil stone and the oil stone are in the sintering space, and the transport mechanism is under the sintering chamber 10. In this way, the oil stone can be sintered in an open flame and high temperature environment, while the transport mechanism is outside the sintering space and will not be directly affected by the open flame and high temperature, which is beneficial to the service life and safety of the transport mechanism. On the other hand, the suspension design facilitates the opening of the bottom of the sintering chamber 10, so that the transport component 20 running on the ground rail can send the oil stone into the sintering chamber 10 by translation.

[0034] The steel frame 1 is made of high temperature resistant materials to ensure long service life and safe use.

[0035] In order to facilitate the transport component 20 to transport the oil stone to the sintering chamber 10, a material inlet and outlet is provided on one side of the sintering chamber 10, and the transport component 20 can transfer the oil stone through the material inlet and outlet; the sintering chamber 10 is also provided with a door 11, which is used to close the material inlet and outlet.

[0036] For details, please refer to Figure 1In the illustrated embodiment, the material inlet and outlet are arranged in an arched structure, and the shape is adapted to the outer shape of the sintering chamber 10 to ensure that the transport component 20 of the multi-layer carrier can pass through the material inlet and outlet into the sintering chamber 10 after loading the oilstone, and ensure full utilization of the space in the sintering chamber 10.

[0037] Continue to refer to Figure 1 The door 11 is rotatably arranged at a side of the sintering chamber 10 where the material inlet and outlet are arranged, through a rotating connection structure such as a hinge and a rotating shaft. By rotating the door 11, the door 11 can be moved closer to or farther away from the material inlet and outlet; when the door 11 is moved closer to close the material inlet and outlet, the sintering chamber 10 is closed, and open-flame sintering can be started; when the door 11 is moved away from the material inlet and outlet, the sintering chamber 10 is opened, and the transport assembly 20 can transfer the oilstone.

[0038] In other embodiments, the door can be opened and closed by translation.

[0039] Optionally, the oilstone sintering furnace further comprises a locking assembly, which is used to fix the door 11 and the sintering chamber 10 to ensure that the door 11 closes the material inlet and outlet.

[0040] The locking assembly may be a locking structure such as a lock buckle or a latch that facilitates fixing the door 11 and the sintering chamber 10 .

[0041] After the transport assembly 20 delivers the oilstone into the sintering chamber 10, the door 11 is closed and the door 11 and the sintering chamber 10 are fixed by the locking assembly, which can avoid the door 11 from being accidentally opened during the sintering process, and further ensure the safety of the sintering furnace.

[0042] In one embodiment, the transport assembly 20 includes: a track 21 extending from the outside of the sintering chamber 10 through the material inlet and outlet to the inside of the sintering chamber 10; and a track trolley 22 slidably disposed on the track 21 for loading oilstone.

[0043] For details, please refer to Figure 1 In the illustrated embodiment, two tracks 21 are arranged on the ground, the two tracks 21 are spaced apart in the left-right direction, and any track 21 is extended in the direction perpendicular to the paper surface; two sets of rollers are provided on the bottom surface of the track trolley 22, and one set of rollers is rollably provided on any track 21; when the rollers rotate, the track trolley 22 can enter the sintering chamber 10 along the track 21; when the rollers rotate in the opposite direction, the track trolley 22 can leave the sintering chamber 10 along the track 21.

[0044] It is easy to understand that the track 21 and the track trolley 22 constitute the transmission mechanism of the transport assembly 20. In order to facilitate the loading of the oilstone, the track trolley 22 can be provided with multiple layers of carriers.

[0045] In one embodiment, the sintering chamber 10 is arranged on a steel frame 1, a material inlet and outlet are arranged on one side of the sintering chamber 10, and an inlet and outlet channel is arranged at the bottom of the sintering chamber 10, and the inlet and outlet channel connects the material inlet and outlet; the transportation component 20 also includes a carrier, which is made of refractory bricks, and the carrier is arranged on a rail trolley 22 for receiving the oil stone; after the transportation component 20 delivers the oil stone into the sintering chamber 10, the carrier can close the inlet and outlet channel, and the rail trolley 22 is located below the sintering space.

[0046] For details, please refer to Figure 2 In the illustrated embodiment, the track 21 is laid on the ground, the track trolley 22 is slidably arranged on the track 21, and a carrier is arranged on the track trolley 22. The sintering chamber 10 is suspended above the ground through the steel frame 1, the track trolley 22 is lower than the sintering chamber 10, and the carrier can enter the sintering chamber 10. After the carrier enters the sintering chamber 10, it can serve as the bottom of the sintering chamber 10 and cooperate with the door 11 to realize the closure of the sintering chamber 10.

[0047] In this way, during the sintering process, the track 21 and the track trolley 22 are both outside the sintering chamber 10, which is beneficial to the safety of the equipment and the safety of use.

[0048] In one embodiment, the transport assembly 20 further includes a transport drive structure, which is used to drive the rollers of the rail trolley 22 to rotate.

[0049] For example, the transport drive structure includes at least one motor, at least one roller connected to the motor and capable of rotating under the drive of the motor. When the roller rotates, it can roll along the track 21, thereby driving the entire track trolley 22 to translate along the track 21.

[0050] For another example, the transport drive structure includes a motor and a screw. A screw is provided at the output end of the motor. The screw extends parallel to the track 21, and the track trolley 22 is threadedly connected to the screw through a nut. When transporting oilstone, the motor starts and drives the screw to rotate. Under the mutual restriction of the track 21 and the roller, the nut drives the track trolley 22 to move linearly along the screw.

[0051] The present application does not limit the specific configuration of the transport drive structure. By setting the transport drive structure, the transport assembly 20 can automatically transport oilstone.

[0052] In another embodiment, the transport assembly 20 further includes a handle 23 , which is disposed on a side of the rail trolley 22 facing away from the sintering chamber 10 ; a worker can push or pull the rail trolley 22 through the handle 23 .

[0053] For details, please refer to Figure 2 In the illustrated embodiment, a handle 23 is provided on the left side of the rail trolley 22. A worker can easily apply force to the rail trolley 22 by acting on the handle 23, so as to push or pull the rail trolley 22 so that the rail trolley 22 enters or leaves the sintering chamber 10.

[0054] It is easy to understand that since the transport assembly 20 is loaded with oilstone and supports the oilstone during the sintering process, the oilstone is in an open flame high temperature environment and is easily heated by heat transfer. If the automatic drive structure is directly installed on the rail trolley 22, it is easy to damage the precise automatic drive structure. Therefore, a handle 23 is provided to facilitate workers to assist the transport assembly 20 in transporting the oilstone.

[0055] Optionally, the handle 23 is detachably disposed on the rail trolley 22 .

[0056] For example, a card hole is provided on one of the handle 23 and the rail trolley 22, and a card block is provided on the other, so that the card block is locked in the card hole to connect the handle 23 and the rail trolley 22, and the card block leaves the card hole to separate the handle 23 and the rail trolley 22.

[0057] For another example, a slide groove is provided on one of the handle 23 and the rail trolley 22, and a slider is provided on the other, so that the slider is inserted into the slide groove to connect the handle 23 and the rail trolley 22, and the slider is disengaged from the slide groove to separate the handle 23 and the rail trolley 22.

[0058] For example, a screw is provided on one of the handle 23 and the rail trolley 22, and a screw hole is provided on the other, so that the screw is threadedly connected to the screw hole to connect the handle 23 and the rail trolley 22, and the screw is disengaged from the screw hole to separate the handle 23 and the rail trolley 22.

[0059] For details, please refer to Figure 3 In the illustrated embodiment, a screw rod is provided on the left side of the rail trolley 22, and a screw hole is provided on the right side of the handle 23, so that the screw rod is inserted into the screw hole and the handle 23 is rotated to threadably connect the handle 23 and the rail trolley 22; the handle 23 is rotated in the opposite direction to separate the handle 23 and the rail trolley 22.

[0060] The present application does not limit the specific installation method of the handle 23 .

[0061] By setting the handle 23 detachable, after the rail trolley 22 delivers the oil stone into the sintering chamber 10, the handle 23 is removed to prevent the handle 23 from heating up along with the rail trolley 22 and the oil stone; after sintering is completed, the handle 23 is put back on the rail trolley 22 to prevent workers from touching high-temperature parts.

[0062] Optionally, the transport assembly 20 further includes an in-place stopper 24 , and the rail trolley 22 can contact the in-place stopper 24 after entering the sintering chamber 10 ; the in-place stopper 24 can prevent the rail trolley 22 from continuing to move, thereby limiting the position of the rail trolley 22 .

[0063] The in-place stopper 24 can be any structure such as a plate, a rod, a wheel, etc. that can resist the track trolley 22 and prevent the track trolley 22 from continuing to move. The in-place stopper 24 can be set on the ground, or on the track 21 or the sintering chamber 10.

[0064] For details, please refer to Figure 2 In the illustrated embodiment, the in-place limit piece 24 is arranged below the sintering chamber 10. When the rail trolley 22 moves from left to right along the track 21 toward the sintering chamber 10, the rail trolley 22 gradually approaches the in-place limit piece 24. When the rail trolley 22 abuts against the in-place limit piece 24, it is restricted by the in-place limit piece 24 and cannot continue to move to the right. At this time, the oil stone carried by the rail trolley 22 is in the sintering space and is located at the preset sintering station.

[0065] By setting the in-place limit piece 24 and limiting the extreme position of the rail trolley 22 for conveying the oilstone, it is possible to prevent the rail trolley 22 from excessive movement and collision with the sintering chamber 10, and to clearly define the in-place position of the rail trolley 22, thereby ensuring that the rail trolley 22 is in a position against the in-place limit piece 24 each time the oilstone is transported, thereby ensuring that the rail trolley 22 is in a uniform position and the oilstone is in a uniform workstation.

[0066] Optionally, the transport assembly 20 further includes a stop limiter 25 . After the rail trolley 22 contacts the position limiter 24 and reaches a preset work position, the stop limiter 25 can fix the rail trolley 22 and prevent the rail trolley 22 from sliding along the rail 21 .

[0067] The stopper 25 may be any structure such as a plate, a rod, a wheel, etc. that can resist the track trolley 22 and prevent the track trolley 22 from moving along the track 21 .

[0068] It is easy to understand that the in-place limiter 24 is used to prevent the rail trolley 22 from moving forward, and the stop limiter 25 is used to prevent the rail trolley 22 from moving backward. Therefore, the in-place limiter 24 and the stop limiter 25 cooperate to fix the rail trolley 22 at a desired position, thereby ensuring the position accuracy and position stability of the rail trolley 22.

[0069] It should be noted that since the rail trolley 22 needs to run, if the stop limiter 25 is installed in advance, the stop limiter 25 may prevent the rail trolley 22 from conveying the oilstone to the sintering chamber 10, and may also prevent the rail trolley 22 from leaving the sintering chamber 10 with the oilstone.

[0070] In one embodiment, the stop limiter 25 is detachably provided.

[0071] Specifically, after the rail trolley 22 abuts against the position limiting member 24, the stop limiter 25 is installed in place so that the stop limiter 25 abuts against the rail trolley 22 from the other side, thereby realizing the front and rear limit of the rail trolley 22. After sintering is completed, the stop limiter 25 is removed, and the rail trolley 22 can move in the reverse direction and leave the sintering chamber 10.

[0072] In this embodiment, the stopper 25 can be detachably arranged on the ground, and can also be detachably arranged on the track 21 or the sintering chamber 10 .

[0073] In this embodiment, the stop limiter 25 can be detachably arranged by means of plug-in, snap-on, screw-on, etc.

[0074] The present application does not limit the specific form and installation position of the stop limiter 25 .

[0075] Optionally, the ignition assembly 30 includes two rows of igniters, and each row includes a plurality of igniters spaced apart along the transport direction; after the transport assembly 20 delivers the oilstone into the sintering chamber 10, the oilstone is located between the two rows of igniters.

[0076] For details, please refer to Figure 1 In the illustrated embodiment, in the sintering chamber 10, two rows of igniters are arranged at intervals along the left and right directions; Figure 2 A row includes five igniters spaced apart in the left-right direction; each igniter is independently connected to a natural gas supply pipeline and can be ignited.

[0077] By providing two rows of igniters and placing the oilstone between the two rows of igniters, it is possible to ensure that the oilstone is surrounded by the sintering environment and the environment in the sintering chamber 10 is balanced, thereby ensuring the sintering effect of the oilstone.

[0078] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
