Description

Technical Field

[0001] The present invention relates to the technical field of heat treatment equipment, and specifically to a heat treatment device for modular catalyst synthesis and preparation. Background Art

[0002] A catalyst generally refers to a substance that increases the reaction rate without changing the total standard Gibbs free energy change of the reaction. The synthesis and preparation of catalysts mainly include the following steps: selecting raw materials and preparing raw material solutions, preparing matrix materials, removing impurities, forming, and heat treatment. Among them, heat treatment is further divided into three steps: preheating, calcination, and cooling.

[0003] Currently, most heat treatment equipment for catalyst synthesis and preparation in laboratories uses a muffle furnace body. The catalyst precursor is placed in a crucible in a sealed manner to form a sample, and then the sample is placed in the inner furnace cavity of the muffle furnace body. Finally, the heat treatment of the catalyst is achieved by controlling the operation of the muffle furnace body. Although the above heat treatment method can achieve the synthesis and preparation of catalysts, it has the following defects: First, there are problems such as uneven heating and crystallization in the overall heat treatment of the catalyst precursor; Second, during the heat treatment of the sample, its preheating, calcination, and cooling are all carried out inside the muffle furnace body. If multiple groups of samples need to be prepared for comparison, the subsequent samples need to wait for the previous samples to complete the heat treatment before they can be processed, which is time-consuming and laborious. Moreover, when the subsequent samples enter the muffle furnace body, it is extremely easy to affect the heat treatment effect of the subsequent samples due to the temperature difference inside the muffle furnace body. Summary of the Invention

On the one hand, it shortens the heat treatment time of the samples and improves work efficiency. On the other hand, it avoids the subsequent samples being affected by temperature difference when entering the inside of the muffle furnace body during heat treatment. Moreover, the burning pot assembly adopts a honeycomb design, enabling it to be freely configured according to requirements, thereby realizing the modular heat treatment of the catalyst and ensuring the uniformity of its heating, so as to solve the problems raised in the above background art.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. By configuring a preheating chamber for sample preheating on the left side of the muffle furnace main body, the preheating chamber is communicated with the inside of the muffle furnace. Then, through the loading mechanism, the preheating treatment of the subsequent sample is realized in a double-station manner during the baking process of the previous sample. On the one hand, the time for sample heat treatment is shortened, and the work efficiency is improved. On the other hand, it is avoided that the subsequent sample is affected by the temperature difference when entering the inside of the muffle furnace main body, thereby affecting its heat treatment effect.

[0028] 2. The loading mechanism is composed of a bearing component and a diversion component. Among them, there are two bearing components, forming a double station, corresponding to the inside of the muffle furnace main body and the inside of the preheating chamber respectively. Then, when the muffle furnace main body operates, the diversion component operates synchronously, extracts a small amount of heat from the inside of the muffle furnace main body, and then transports it to the inside of the preheating chamber, so as to realize the preheating treatment of the potting component located inside the preheating chamber.

[0029] 3. When the diversion component in the loading mechanism approaches the main body of the muffle furnace as the loading component moves to the right, since the air outlet pipes in the diversion component are repositioned, the larger air holes on the air outlet pipes can correspond to the air outlet channels. At this time, the ejected air flow can play a certain role in cooling and cleaning the interior of the muffle furnace main body, further reducing the manual burden and minimizing the temperature difference that the subsequent samples endure when entering the interior of the muffle furnace main body.

[0030] 4. By setting the adjustment mechanism, synchronous opening and closing operations of the cabinet door, barrier door, and baffle of the preheating chamber in the main body of the muffle furnace can be achieved, reducing the manual operation burden and further improving work efficiency.

[0031] 5. The burning pot component adopts a honeycomb design, enabling it to be freely configured according to requirements, thereby realizing modular heat treatment of the catalyst and ensuring the uniformity of its heat reception. Description of the Drawings

[0054] Limit members 5 are symmetrically arranged on the front and rear of the bottom inner wall of the inner furnace body 12. The loading mechanism includes a bearing assembly 4 and a diversion assembly 7. Among them, the bearing assembly 4 is located between the two limit members 5, and the diversion assembly 7 is arranged at the left end of the bearing assembly 4. The movement of the bearing assembly 4 can drive the diversion assembly 7 to move synchronously.

[0055] Please refer to Figures 3 - 5 , in the embodiment of the present invention, the adjusting mechanism 3 includes a housing cover 31 fixedly connected to the top outer wall of the outer furnace body 11 by bolts, and a motor 32 is installed on the top outer wall of the housing cover 31 by screws.

[0056] A transmission shaft is provided at the output end of the motor 32. The bottom end of the transmission shaft penetrates the top wall of the housing cover 31 and is provided with a convex disc 34. The transmission shaft and the pin shaft are linked through a chain member 33 to drive the cabinet door 13 to open and close for adjustment. A blocking assembly 35 is provided on the left side of the convex disc 34 on the muffle furnace body 1 for blocking the left end of the inner furnace body 12.

[0057] An annular groove is formed in the circumferential wall of the convex disc 34, and a moving block is slidably connected in the annular groove. The bottom of the moving block is slidably connected to the top wall of the outer furnace body 11. Further, when the convex disc 34 rotates, the moving block makes a linear displacement adjustment.

[0058] The barrier assembly 35 includes a passage groove formed in the top shell wall of the inner furnace body 12. An accommodation groove is formed in the outer furnace body 11 above the passage groove. A barrier door 351 for plugging is inserted into the passage groove. When the barrier door 351 moves upward, it is located in the accommodation groove.

[0059] The barrier door 351 is provided with holes for air passage, and lifting rods 352 are symmetrically arranged at the front and rear of the top of the barrier door 351. The bottom of the barrier door 351 is also adjusted accordingly to adapt to the bearing assembly 4.

[0060] The tops of the two lifting rods 352 both extend above the outer furnace body 11, and a splicing member 353 is jointly installed. The splicing member 353 is symmetrically and movably connected with support rods 354 at the front and rear. The bottom end of the support rod 354 is provided with a sliding seat, and the bottom of the sliding seat is slidably connected to the top shell wall of the outer furnace body 11. When the sliding seat is displaced, the splicing member 353 is lifted through the support rod 354, and then the synchronous movement of the barrier door 351 is realized under the action of the lifting rod 352.

[0062] A traction rope is installed on the side wall of each sliding seat, and the other end of the traction rope is fixedly connected to a moving block.

[0063] Cylinders are symmetrically arranged at the front and rear on the top shell wall of the outer furnace body 11 for winding the corresponding traction ropes. When the moving block moves, the traction rope is pulled. Due to the turning of the traction rope through the cylinders, the sliding seat can be pulled and adjusted while the moving block moves linearly.

[0064] A connecting plate 36 is connected to the side wall of the L-shaped plate through a movable pin, and the bottom end of the connecting plate 36 is movably connected to a U-shaped seat through a plug pin.

[0065] Please refer to Figures 4 - 6 In the embodiment of the present invention, the bearing assembly 4 includes slide rails symmetrically arranged on the bottom inner wall of the inner furnace body 12. A sliding sleeve 41 is slidably connected to the slide rails. An activity groove is formed on the top shell wall of each sliding sleeve 41. The two sliding sleeves 41 are combined through a cross beam, and thus the synchronous pushing and pulling adjustment of the two sliding sleeves 41 can be realized through the cross beam. The tops of the two sliding sleeves 41 are jointly and movably connected with a supporting member 42. Among them, there are two supporting members 42 for placing the corresponding cooking pot assembly 6.

[0066] The supporting member 42 includes a tray located above the sliding sleeve 41. A towing handle is integrally provided on the right side of the tray, and a plurality of movable rods are arranged in a matrix at the bottom of the tray. The plurality of movable rods are grouped in pairs and are respectively movably connected to the corresponding movable slots.

[0067] The limiting member 5 includes a notch opened on the inner wall of the bottom of the inner furnace body 12. Straight plates are symmetrically arranged at the front and rear of the top of the notch. A swing rod is movably connected between the two straight plates through a pin shaft, and a counterweight is integrally provided at the bottom end of the swing rod. Due to the arrangement of the weight block at the left end, the swing rod is always in a state of being lower on the left and higher on the right under the action of gravity.

[0068] Please refer to Figures 7 - 9 , in the embodiment of the present invention, the cooking pot assembly 6 includes a chassis 61 placed on the supporting member 42. A plurality of honeycomb members 62 are stacked on the top of the chassis 61 from bottom to top for modular stacking of the catalyst.

A plurality of positioning rod groups are arranged along the circumferential direction on the bottom shell wall of the lower auxiliary plate. The positioning rod groups and the positioning hole groups are inserted and limited to ensure the stability when two honeycomb members 62 are stacked. A plurality of ventilation holes are opened on the top and bottom shell walls of the honeycomb frame. The setting of the arc-shaped convex platforms ensures sufficient airspace even when two honeycomb members 62 are stacked, and the ventilation holes ensure the uniformity of heat received by the sample during the heat treatment process.

[0070] Please refer to Figures 10 - 15 , in the embodiment of the present invention, the flow guiding assembly 7 includes side plates 71 provided on the left ends of the two sliding sleeves 41. An embedded groove is opened on the left shell wall of the side plate 71. A main body of a suction fan 72 is placed in the embedded groove. An intake pipe is installed at the intake end of the main body of the suction fan 72. The other end of the intake pipe penetrates through the side plate 71 and is butted against a hole on the barrier door 351. Thus, the heat in the muffle furnace body 1 can be extracted and borrowed.

[0071] A through hole is opened on the side plate 71 below the embedded groove. An air outlet pipe 73 is rotatably connected in the through hole. Two groups of air holes are linearly opened on the peripheral wall of the air outlet pipe 73. The two groups of air holes are arranged oppositely, and the apertures of the two groups of air holes are different. This is convenient for preheating the inside of the preheating chamber 2 and can also cool and clean the inner cavity of the inner furnace body 12. An air delivery pipe is installed at the air outlet end of the main body of the suction fan 72. The two ends of the air delivery pipe respectively extend into the two ends of the air outlet pipe 73.

[0072] An air outlet channel is formed in the right shell wall of the side plate 71, and the air outlet channel is in communication with the through hole.

[0073] Gears 74 are installed on the outer circles of both ends of the air outlet pipe 73, and racks 75 meshing with the gears 74 are arranged below the gears 74. A pushing rod 76 is installed at the left end of the rack 75. The end of the pushing rod 76 away from the rack 75 penetrates through the corresponding side wall of the side plate 71, and a contact disc is installed. A return spring is sleeved on the pushing rod 76. Under the action of the return spring, the pushing rod 76 can drive the rack 75 to move when there is no external force on the contact disc. Then, the rack 75 meshes with the gear 74 to drive the air outlet pipe 73 to rotate and switch.

[0074] The working principle of the present invention is as follows: During the synthesis and preparation of the catalyst, the catalyst precursor is first modularly sealed, and then each sealed modular catalyst precursor is inserted into the pot assembly 6 to form a sample to be processed.

[0075] During the loading process of the modular catalyst precursor in the pot assembly 6, first, a honeycomb part 62 is placed on the top of the supporting part 42 in the pot assembly 6, and then each modular catalyst precursor is sequentially inserted into the slots of the honeycomb part 62. When the slots of the honeycomb part 62 are full, another honeycomb part 62 is placed on the top of the honeycomb part 62, and then the modular catalyst precursors are inserted and stacked to form a sample to be processed. After all the samples are stacked, the motor 32 in the adjusting mechanism 3 is started through the control panel on the muffle furnace main body 1 to make the transmission shaft move, open the cabinet door 13 of the muffle furnace main body 1 through the chain gear part 33, and move the moving block to the right through the convex disc 34.

[0076] The rightward movement of the moving block enables the traction rope bound to it to move, thereby driving the movement of the support rod 354 in the barrier component 35, causing the splicing part 353 to move upward. The upward movement of the splicing part 353 lifts the barrier door 351 through the lifting rod 352, and the upward movement of the splicing part 353 also drives the adjusting arm 23 in the preheating chamber 2 to move rightward through the connecting plate 36, thereby causing the baffle 22 to move upward and open. At this time, two samples to be processed can be selected and placed on the supporting member 42 in the preheating chamber 2 and the supporting member 42 in the inner furnace body 12 respectively. Then, the motor 32 in the adjusting mechanism 3 is started to move in the reverse direction through the control panel of the muffle furnace body 1, so as to realize the reset of the cabinet door 13, the barrier component 35 and the baffle 22. Finally, the muffle furnace body 1 is started through the control panel of the muffle furnace body 1 to perform heat treatment on the samples placed inside it. When the muffle furnace body 1 performs heat treatment on the samples in the inner furnace body 12, the exhaust fan body 72 in the diversion component 7 is synchronously turned on. When the exhaust fan body 72 operates, a part of the hot air in the inner furnace body 12 is extracted through the air inlet pipe, and then is input into the air outlet pipe 73 under the action of the air delivery pipe. The gas entering the air outlet pipe 73 is discharged from the air holes, and then is discharged into the preheating chamber 2 through the air outlet channel to preheat the samples located therein.

[0077] Since the diversion component 7 is close to the right side wall of the housing 21 in the preheating chamber 2 at this time, the contact disks on each pushing rod 76 drive the rack 75 to move rightward when contacting the right inner wall of the housing 21, stretching the return spring. The rack 75 and the gear 74 are in meshing transmission, thereby driving the air outlet pipe 73 to rotate and move, so that among the two groups of air holes on the air outlet pipe 73, the air outlet with a smaller diameter faces the air outlet channel, avoiding the temperature in the preheating chamber 2 from being too high.

[0078] When the muffle furnace body 1 finishes baking the samples, the temperature is gradually reduced through the control program in the muffle furnace body 1. When the samples in the inner furnace body 12 reach the temperature requirement for discharging, the motor 32 in the adjusting mechanism 3 is started again through the control panel of the muffle furnace body 1, so that the cabinet door 13, the barrier component 35 and the baffle 22 are opened again.

[0079] After the cabinet door 13 is opened, the cross beam in the bearing component 4 is pulled by an external pull rod, so that the sliding sleeve 41 in the bearing component 4 moves rightward. At this time, since the samples located in the inner furnace body 12 have a certain weight and the supporting member 42 is in sliding contact with the sliding sleeve 41, when the sliding sleeve 41 moves, it is difficult for the supporting member 42 to move stably to the outside of the inner furnace body 12 together with the sliding sleeve 41. However, since the supporting member 42 in the preheating chamber 2 is at the left limit position of the movable groove on the sliding sleeve 41, it moves together with the movement of the sliding sleeve 41.

[0080] After the carrier 42 in the preheating chamber 2 moves into the inner furnace body 12 along with the sliding sleeve 41, the carrier 42 carrying the preheated sample contacts the carrier 42 carrying the sample that has completed the heat treatment while continuously moving along with the sliding sleeve 41, and then pushes it. When the carrier 42 on the left moves continuously to the right along with the sliding sleeve 41, the carrier 42 contacts the stopper 5 located in the inner furnace body 12 and pushes and presses it. When the carrier 42 completely moves to the right side of the stopper 5, the dragging of the sliding sleeve 41 to the right stops. The carrier 42 pushed out of the inner furnace body 12 is further pulled to the right to completely leave the inner furnace body 12, so as to facilitate the taking of the sample on it.

[0081] When the sliding sleeve 41 moves, it synchronously drives the diversion assembly 7 to move together. After the diversion assembly 7 moves to the right, the contact disk lacks extrusion pressure, and thus, under the action of the return spring, the push rod 76 drives the rack 75 to reset. The cooperation between the rack 75 and the gear 74 causes the air outlet pipe 73 to rotate and switch, so that the larger-diameter air holes on the air outlet pipe 73 correspond to the air outlet channels. When the sliding sleeve 41 moves to the maximum distance to the right, the diversion assembly 7 seals the left end of the inner furnace body 12. At this time, the air discharged from the air outlet channels cools and cleans the inner cavity of the inner furnace body 12.

[0082] After the sample that has completed the heat treatment is taken away, the carrier 42 carrying the sample is taken, and then the sliding sleeve 41 is pushed back to its original position. Since the carrier 42 located in the inner furnace body 12 is on the right side of the stopper 5 at this time, the carrier 42 will slide on the sliding sleeve 41 during the reset process of the sliding sleeve 41 and maintain its current position, which is convenient for heat treatment of the sample.

[0083] The removed carrier 42 is placed on the sliding sleeve 41 through the rectangular notch of the housing 21, and then a new sample to be processed is placed on the carrier 42. Finally, the motor 32 in the adjustment mechanism 3 is started to move in the reverse direction through the control panel on the muffle furnace body 1, so as to realize the reset and closing of the cabinet door 13, the barrier assembly 35 and the baffle 22, and start the muffle furnace body 1 to perform heat treatment on the sample inside it. This process is repeated to realize the rapid heat treatment of multiple groups of samples.

[0084] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
