Description

Technical Field

[0001] This invention relates to the field of chemical technology, specifically to a roasting apparatus with sustainable heating. Background Technology

[0002] Chemical industry is an abbreviation for "chemical process", "chemical industry", "chemical engineering", etc. All technologies that use chemical methods to change the composition and structure of substances or synthesize new substances belong to chemical production technology, also known as chemical process. The products obtained are called chemical products. Initially, these products were produced in handicraft workshops, which later evolved into factories and gradually formed a specific production industry, namely the chemical industry.

[0003] Calcination is a common chemical process. During catalyst preparation, a certain amount of moisture and other organic matter or impurities often remain, which can poison the catalyst and affect the catalytic reaction. Calcination removes these impurities and moisture, improving the catalyst's purity. Calcination also promotes crystal growth within the catalyst, enhancing its stability and activity. Furthermore, calcination increases the catalyst's pore structure and specific surface area, increasing the opportunity for contact between the catalyst and reactants, thereby improving the reaction rate.

[0004] Currently, the roasting kilns used in laboratories directly discharge the waste gas generated by the evaporation of free water from the catalyst semi-finished product to the outside of the kiln without filtration. This not only pollutes the environment and causes harm to experimental personnel, but also, since the existing equipment lacks the means to continue heating and insulation during power outages, impurities will clog the exhaust pipe if the flue gas is not filtered, thus affecting the heating and insulation performance of the equipment. In view of this, we propose a roasting device with sustainable heating. Summary of the Invention

The arc-shaped outer wall of the roasting kiln is fixedly connected to the arc-shaped outer wall of the exhaust pipe. A round rod is rotatably installed on the inner wall of the exhaust pipe. The arc-shaped outer wall in the middle of the round rod is fixedly connected to the arc-shaped inner wall of the impeller center.

A spring is fixedly connected to one end of the ring block sidewall, and the end of the spring away from the ring block is fixedly connected to one sidewall of the filter plate. The arc-shaped sidewall of the exhaust pipe is threadedly connected to the top of the collection tank.

[0007] Preferably, the exhaust pipe is located between two fixed sleeves, with one end of the exhaust pipe penetrating through and extending into the arc-shaped sidewall of the roasting kiln, and the extended end being located on the upper side of the roasting kiln to prevent materials inside the roasting kiln from entering the exhaust pipe.

[0008] Preferably, the circular motion trajectory of the end of the striking rod away from the round rod intersects the vertical plane where the filter plate is stationary. There are two striking rods, which are symmetrically arranged on both sides of the round rod with the vertical center line as the axis of symmetry. The filter plate is located inside the round rod, and the interface between the collection tank and the exhaust pipe is located inside the annular block. The collection tank is located directly below the roasting kiln so that impurities can fall into the collection tank better by their own gravity.

[0009] Preferably, the number of springs is set to multiple, and they are arranged in an evenly spaced circular array on the outer sidewall with the center of the circular cross-section of the ring block as the array center line, so as to improve the reset effect of the filter plate.

[0010] Preferably, the heating component includes a gas pipe valve, the gas pipe valve is fixedly installed on the arc-shaped sidewall of the right end of the exhaust pipe, and a heater is fixedly installed on the top outer side of the plate.

[0011] Preferably, each of the left and right output ends of the heater is fixedly connected to one end of a conduit. The ends of the two conduits away from the heater extend into the interior of the kiln from the bottom arc-shaped sidewall. The ends of the two conduits extending into the kiln are respectively fixedly connected to the left and right ends of the heating rod between the arc-shaped outer walls. The connection between the arc-shaped outer walls of the conduits and the inner wall of the kiln is sealed to prevent material from leaking from the inside of the kiln.

[0012] Preferably, the top of the plate is provided with a rotating mechanism, the rotating mechanism includes a servo motor, the servo motor is fixedly installed on the left side wall of the roasting kiln, and a thin rod is fixedly installed on the right arc-shaped inner wall of the roasting kiln, with the inner wall of the center of the thin rod fixedly connected to the arc-shaped outer wall of the sleeve.

[0013] Preferably, the output end of the servo motor is fixedly connected to the left side wall of the auger rod, the left arc-shaped outer wall of the auger rod is rotatably connected to the inside of the left side wall of the roasting kiln, and the right arc-shaped outer wall of the auger rod is rotatably connected to the inner arc-shaped wall of the circular sleeve.

[0014] Preferably, the circular motion trajectory of the outermost end of the auger rod does not intersect with the end of the exhaust pipe that extends into the kiln or the heating rod, to prevent the rotation of the auger rod from interfering with the motion of the two.

[0015] Preferably, the bottom of the plate is provided with an auxiliary component, a base, and support legs are fixedly installed at the four corners of the bottom of the base. Rotary rods are rotatably installed at the left and right ends of the top of the base. One of the rotary rods on the right side is fixedly connected to the right end of the plate, and the arc-shaped sidewall of the rotary rod on the left side is fixedly connected to the bottom end of a hydraulic cylinder. The top end of the hydraulic cylinder is fixedly connected to the bottom left side of the plate. There are two hydraulic cylinders, which are symmetrically arranged on the inner and outer bottom sides of the plate with the horizontal center line in the left and right direction as the axis of symmetry, so as to make the rotation of the plate more stable.

[0016] Compared with the prior art, the present invention provides a roasting device with sustainable heating, which has the following beneficial effects: 1. This sustainable heating roasting device is equipped with a filter assembly to better intercept and filter impurities in the exhaust gas during the roasting process. When the materials inside the roasting kiln undergo a chemical reaction, a large amount of exhaust gas is generated and passes through the exhaust pipe. This, in conjunction with the impeller and the round rod, drives the striking rod to rotate, which, in conjunction with the ring block and the spring, causes the filter plate to reciprocate. As impurities are intercepted by the filter plate, the vibration of the filter plate causes them to fall into the collection tank more quickly and not adhere to the filter plate, thus keeping the exhaust pipe unobstructed and ensuring that the subsequent heating components are not affected.

[0017] 2. This continuously heated roasting device is equipped with a heating component to better provide continuous heating to the materials and prevent heat loss during power outages. When the heater is started, it can continuously heat the materials inside the roasting kiln in conjunction with the conduit and heating rod. At this time, the gas pipe valve is open, and the hot gas generated by the reaction can also use the waste heat of the exhaust gas to further heat the roasting kiln when it passes through the exhaust pipe. When the power is cut off, the gas pipe valve is closed, and the waste heat of the exhaust gas inside the exhaust pipe can temporarily keep the materials warm.

[0018] 3. This continuously heated roasting device is equipped with a rotating mechanism to better agitate the materials and ensure a full reaction. When the servo motor is started, it works with the thin rod to make the auger rod rotate between the roasting kiln and the circular sleeve. This allows the auger rod to fully agitate the materials and ensure a full reaction. Furthermore, when the auxiliary components are used to raise the hydraulic cylinder, the auger rod can also make the materials discharge from the discharge pipe more quickly.

[0019] 4. This continuously heated roasting device, in order to make the material reaction more complete, works with the base and rotating rod. When the hydraulic cylinder is activated, the roasting kiln reciprocates, which allows the material inside to move fully. With the rotation of the auger rod in the rotating mechanism, the material can be heated more evenly. Finally, the roasting kiln is completely raised, and the control valve on the outside of the discharge pipe is opened, making the discharge more convenient. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-6The present invention provides a technical solution: a roasting device with sustainable heating, including a plate 1, with fixing sleeves 2 fixedly installed at the left and right ends of the top of the plate 1, the fixing sleeves 2 serving to fix and support the roasting kiln 3, the arc-shaped inner walls of the top of the two fixing sleeves 2 being fixedly connected to the arc-shaped outer walls of the left and right ends of the roasting kiln 3 respectively, the arc-shaped side wall of the top of the left end of the roasting kiln 3 being fixedly connected to the arc-shaped outer wall of the feed pipe 4, the arc-shaped side wall of the right end of the roasting kiln 3 being fixedly connected to the side wall of the discharge pipe 5, and control valves 6 being fixedly installed on the arc-shaped side walls of both the feed pipe 4 and the discharge pipe 5, and a filter assembly 7 and a heating assembly 8 being provided on the top of the plate 1.

[0024] Please see Figure 2-6In one embodiment of the present invention, the filter assembly 7 includes an exhaust pipe 71. The exhaust pipe 71 is arranged around the outside of the calcining kiln 3. The arc-shaped outer wall of the calcining kiln 3 is fixedly connected to the arc-shaped outer wall of the exhaust pipe 71. A round rod 72 is rotatably installed on the inner wall of the exhaust pipe 71. The arc-shaped outer wall of the middle part of the round rod 72 is fixedly connected to the arc-shaped inner wall of the center of the impeller 73. When the catalyst semi-finished product inside the calcining kiln 3 undergoes a chemical reaction, a large amount of waste gas generated by the evaporation of free water inside will pass through the exhaust pipe 71. The airflow will drive the impeller 73 to rotate, thereby causing the round rod 72 to rotate. The arc-shaped outer walls at both ends of the round rod 72 are fixedly connected to the exhaust pipe 71. The inner arc of one end of the striking rod 74 is connected to the outer arc of the ring block 75, causing the striking rod 74 to rotate. The inner arc of the exhaust pipe 71 is fixedly connected to the outer arc of the ring block 75. One end of the spring 76 is fixedly connected to the side wall of the ring block 75. The end of the spring 76 away from the ring block 75 is fixedly connected to the side wall of the filter plate 77, thus cooperating with the ring block 75. When the striking rod 74 contacts the filter plate 77, it causes the filter plate 77 to move to one side. At this time, the spring 76 is compressed and deformed. When the striking rod 74 leaves the filter plate 77, the spring 76 releases its elastic force, causing the filter plate 77 to return to its original position in the opposite direction, thus making the filter plate 77 reciprocate. The exhaust pipe 71 is threaded to the top of the collection tank 78 via an arc-shaped sidewall. This allows impurities to be intercepted by the filter plate 77, and the vibration of the filter plate 77 causes them to fall more quickly into the collection tank 78, preventing them from adhering to the filter plate 77. This keeps the exhaust pipe 71 unobstructed, ensuring that the subsequent heating components 8 are not affected. The exhaust pipe 71 is located between two fixed sleeves 2. One end of the exhaust pipe 71 penetrates the arc-shaped sidewall of the kiln 3 and extends into it, with this extended end located on the upper side of the kiln 3. This prevents materials inside the kiln 3 from entering the exhaust pipe 71. The striking rod 74 moves in a circular motion at the end furthest from the round rod 72. The trajectory intersects with the vertical plane where the filter plate 77 is stationary. There are two striking rods 74, which are symmetrically arranged on both sides of the vertical center line of the round rod 72. The filter plate 77 is located inside the round rod 72. The interface between the collection tank 78 and the exhaust pipe 71 is located inside the annular block 75. The collection tank 78 is located directly below the roasting kiln 3 so that impurities can fall into the collection tank 78 better by their own gravity. There are multiple springs 76, which are evenly spaced in a circular array on the outer sidewall with the center of the circular cross-section of the annular block 75 as the array center line, so as to improve the reset effect of the filter plate 77.

[0025] Please see Figure 2-4In one embodiment of the present invention, the heating assembly 8 includes a gas pipe valve 81, a heater 82, a conduit 83, and a heating rod 84. A gas pipe valve 81 is fixedly installed on the arc-shaped sidewall of the right end of the exhaust pipe 71. A heater 82 is fixedly installed on the top outer side of the plate 1. One end of a conduit 83 is fixedly connected to the output ends of both sides of the heater 82. The ends of the two conduits 83 furthest from the heater 82 extend into the interior of the kiln 3 from the arc-shaped sidewall at the bottom. Heating rods 84 are fixedly connected between the arc-shaped outer walls of the ends of the two conduits 83 extending into the kiln 3. At both ends on the right, when the heater 82 is started, in conjunction with the conduit 83 and the heating rod 84, the material inside the roasting kiln 3 can be continuously heated. At this time, the gas pipe valve 81 is in the open state. When the hot gas generated by the reaction passes through the exhaust pipe 71, the residual heat of the waste gas can also be used to further heat the roasting kiln 3. When the power is cut off, the gas pipe valve 81 is closed, and the residual heat of the waste gas inside the exhaust pipe 71 can temporarily keep the material warm. The connection between the arc-shaped outer wall of the conduit 83 and the inner wall of the roasting kiln 3 is in a sealed state to prevent the material from leaking from the inside of the roasting kiln 3.

[0026] Please see Figure 2-4 In one embodiment of the present invention, a rotating mechanism 9 is provided on the top of the plate 1. The rotating mechanism 9 includes a servo motor 91. The servo motor 91 is fixedly installed on the left side wall of the roasting kiln 3. A thin rod 92 is fixedly installed on the right arc-shaped inner wall of the roasting kiln 3. The inner wall of the center of the thin rod 92 is fixedly connected to the arc-shaped outer wall of the circular sleeve 93. The output end of the servo motor 91 is fixedly connected to the left side wall of the auger rod 94. The left arc-shaped outer wall of the auger rod 94 is rotatably connected to the inside of the left side wall of the roasting kiln 3. The right arc-shaped outer wall of the auger rod 94 is rotatably connected to the arc-shaped inner wall of the circular sleeve 93. When The servo motor 91 is started, which, in conjunction with the thin rod 92, causes the auger rod 94 to rotate between the inside of the side wall of the roasting kiln 3 and the circular sleeve 93. This allows the auger rod 94 to fully stir the material and ensure a complete reaction. Furthermore, when the auxiliary component 10 is used to raise the hydraulic cylinder 104, the auger rod 94 can also allow the material to be discharged from the discharge pipe 5 more quickly. The circular motion trajectory of the outermost end of the auger rod 94 does not intersect with the end of the exhaust pipe 71 that extends into the roasting kiln 3 or the heating rod 84, preventing the rotation of the auger rod 94 from interfering with the motion of these two parts.

[0027] Please see Figure 2-3In one embodiment of the present invention, an auxiliary component 10 is provided at the bottom of the plate 1, and a base 101 is provided at the bottom of the plate 1. Support legs 102 are fixedly installed at the four corners of the bottom of the base 101. Rotating rods 103 are rotatably installed at the left and right ends of the top of the base 101. One rotating rod 103 on the right side is fixedly connected to the right end of the plate 1, and the arc-shaped side wall of the rotating rod 103 on the left side is fixedly connected to the bottom end of the hydraulic cylinder 104. The top end of the hydraulic cylinder 104 is fixedly connected to the bottom left side of the plate 1. When the hydraulic cylinder 104 is started, the roasting kiln 3 is reciprocated, thereby allowing the material inside to move fully. With the help of the auger rod 94 in the rotating mechanism 9, the material can be heated more evenly, and finally the roasting kiln 3 is completely lifted. Opening the control valve 6 on the outside of the discharge pipe 5 makes the discharge more convenient. There are two hydraulic cylinders 104, which are symmetrically arranged on the bottom of the inner and outer sides of the plate 1 with the horizontal center line in the left and right direction as the axis of symmetry, so as to make the rotation of the plate 1 more stable.

[0028] Working principle: When the catalyst semi-finished product inside the roasting kiln 3 undergoes a chemical reaction, a large amount of waste gas generated by the evaporation of free water inside passes through the exhaust pipe 71. This airflow drives the impeller 73 to rotate, which in turn causes the circular rod 72 to rotate, thereby driving the striking rod 74 to rotate. This, in conjunction with the circular ring block 75, causes the striking rod 74 to contact the filter plate 77, making the filter plate 77 move to one side. At this time, the spring 76 is compressed and deformed. When the striking rod 74 leaves the filter plate 77, the spring 76 releases its elastic force, causing the filter plate 77 to return to its original position in the opposite direction. This reciprocating motion of the filter plate 77 allows impurities to be intercepted by the filter plate 77, and the vibration of the filter plate 77 causes them to fall more quickly into the collection tank 78, preventing them from adhering to the filter plate 77. This keeps the exhaust pipe 71 unobstructed, ensuring that the subsequent heating components 8 are not affected. Furthermore, when the heater 82 is started, in conjunction with the conduit 83 and the heating rod 84, continuous heating can be provided to the material inside the roasting kiln 3. When valve 81 is open, the hot gas generated during the reaction passes through exhaust pipe 71, and the residual heat of the exhaust gas can be used to further heat the roasting kiln 3. When the power is off, valve 81 is closed, and the residual heat of the exhaust gas inside exhaust pipe 71 can temporarily keep the material warm. Furthermore, when servo motor 91 is started, it works with thin rod 92 to make auger rod 94 rotate between the inside of the side wall of roasting kiln 3 and the circular sleeve 93, so that auger rod 94 can fully stir the material and make it react fully. When it works with auxiliary component 10 to raise hydraulic cylinder 104, auger rod 94 can also make the material discharge from discharge pipe 5 more quickly. Furthermore, when hydraulic cylinder 104 is started, roasting kiln 3 is rotated back and forth, so that the material inside it moves fully. With the help of auger rod 94 in rotating mechanism 9, the material can be heated more evenly. Finally, roasting kiln 3 is completely raised, and control valve 6 on the outside of discharge pipe 5 is opened, so that the material can be discharged more conveniently.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
