Description

Technical Field

[0001] This utility model belongs to the field of catalyst production technology, specifically relating to a rapid cooling device for catalyst production and preparation. Background Technology

[0002] Particulate catalysts are a class of solid catalysts with specific geometric shapes and sizes, typically ranging from micrometers to millimeters in size. Common morphologies include spherical, cylindrical, plate-like, and ring-shaped particles. This morphology gives them excellent flowability and packing properties in industrial reaction equipment, allowing them to be uniformly distributed in the reaction system and fully contact the reactants, thus maximizing their catalytic effect. Particulate catalysts have extremely wide applications in industrial production. For example, in the petrochemical industry, molecular sieve particulate catalysts used in catalytic cracking processes can convert heavy oil into light gasoline, diesel, and other products; in the environmental protection field, activated carbon particulate catalysts used to treat industrial waste gases can adsorb and decompose harmful gases; and in the energy field, platinum-based particulate catalysts in fuel cells can promote the hydrogen-oxygen reaction, realizing the conversion of chemical energy into electrical energy.

[0003] In the catalyst production process, the catalyst must undergo a cooling process after the high-temperature reaction before it can be further processed. However, many catalysts are sensitive to moisture and cannot be cooled by water, relying instead on natural cooling or axial fan cooling. Natural cooling is extremely time-consuming, wasting a significant amount of time waiting for the catalyst to cool down, which greatly slows down the production pace. On the other hand, simple air cooling is also not fast enough to meet the requirements of high-efficiency production. Utility Model Content

[0004] The purpose of this invention is to provide a carton palletizing and conveying device that follows and positions the cartons to solve the above problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a rapid cooling device for catalyst production and preparation, comprising a base, support frames installed on both sides of the top of the base, a cooling box fixedly installed at the upper end between the support frames, a cooling conveying pipe fixedly installed on the inner side wall of the cooling box, a condensing coil fixedly sleeved at the middle of the outer side wall of the cooling conveying pipe, a heat insulation sleeve fixedly sleeved on the outer side wall of the condensing coil, a condensate inlet pipe and a condensate outlet pipe respectively connected to both ends of the condensate inlet pipe and the condensate outlet pipe, the other ends of the condensate inlet pipe and the condensate outlet pipe respectively penetrating the side wall of the cooling box and connected together to a condensate cooling circulation device.

[0006] As a further optimization of this utility model, a feed inlet is installed on one side of the top center of the cooling box, a throttle valve is fixedly installed on the inner side wall of the feed inlet, and a feed pipe connected to the feed end of the cooling conveying pipe is connected to the top of the feed inlet.

[0007] As a further optimization of this utility model, a spiral conveying rod is rotatably connected to the middle position of the inner side wall of the cooling conveying pipe, and a second servo motor is fixedly installed on the side wall of any of the support frames, with the output end of the second servo motor fixedly connected to one end of the spiral conveying rod.

[0008] As a further optimization of this utility model, a discharge pipe is connected to the bottom of the cooling conveying pipe and the side away from the feed pipe, and a heat dissipation box is connected to the bottom of the discharge pipe.

[0009] As a further optimization of this utility model, guide blocks are installed on both sides of the middle of the inner sidewall of the heat sink, a cooling fan is fixedly installed in the middle of the front sidewall of the heat sink between the two guide blocks, and a cooling filter is installed on the rear sidewall of the heat sink behind the cooling fan.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, a condensing coil is tightly fitted around the cooling feed pipe. The surrounding layout increases the contact area with the cooling feed pipe, which can more efficiently absorb the heat of the catalyst inside the pipe and accelerate the cooling speed. The heat insulation sleeve outside the condensing coil can reduce the heat loss to the outside, ensure that the cooling energy is concentrated on the catalyst, and improve the cooling efficiency.

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example 1

[0025] like Figures 1-4As shown, a rapid cooling device for catalyst production includes a base 1. Support frames 8, made of high-strength metal, are bolted to both sides of the top of the base 1 to securely support a cooling box 9. Mounting frames 5 are symmetrically mounted on both sides of the top center of the base 1. A feeding conveyor belt 2 is rotatably connected between two mounting frames 5 via bearings. Several arrayed drive rollers are rotatably connected inside the feeding conveyor belt 2, providing support and transmission for its operation. A transmission assembly 3 is bolted to the side wall of any mounting frame 5. 3 includes a synchronous pulley that cooperates with several transmission rollers and a synchronous belt sleeved on the outer wall of the synchronous pulley. The synchronous pulley and the synchronous belt cooperate to realize the synchronous rotation of multiple transmission rollers. The side wall of another mounting bracket 5 is fixedly mounted with a first servo motor 4 by bolts. The output end of the first servo motor 4 is fixedly connected to the side wall of any transmission roller through a coupling to provide power for the operation of the feeding conveyor belt 2. The top of the base 1 is provided with a sliding groove. The collection box 7 is slidably connected to the base 1 through the sliding groove and is located at the bottom of the feeding conveyor belt 2. It is used to collect the cooled catalyst conveyed by the feeding conveyor belt 2.

[0026] like Figures 1-5As shown, a cooling box 9 is fixedly installed at the upper end between the two support frames 8 by welding. A cooling conveying pipe 15 is fixedly installed on the inner wall of the cooling box 9 by bolts. The cooling conveying pipe 15 is a metal pipe with good thermal conductivity to facilitate heat transfer. A condensing coil 16 is fixedly sleeved in the middle of the outer wall of the cooling conveying pipe 15 by clamps. The condensing coil 16 is made of copper and has good thermal conductivity. A heat insulation sleeve 17 is fixedly sleeved on its outer wall. The heat insulation sleeve 17 is made of high-temperature resistant heat insulation material to reduce heat exchange between the condensing coil 16 and the external environment. The two ends of the condensing coil 16 are respectively connected to a condensate inlet pipe 13 and a condensate outlet pipe 14 through flanges. The other ends of the condensate inlet pipe 13 and the condensate outlet pipe 14 pass through the side wall of the cooling box 9 and are connected to a condensate cooling circulation device (not shown in the figure) through a pipe. The condensate is transported to the condensate circulation box through the circulation pump connected by the pipe outlet pipe 14. The condensate circulation tank includes an evaporator installed inside the tank, through which refrigerant (such as Freon) flows. The evaporator absorbs heat from the condensate through heat exchange, lowering its temperature. The condensate cooling circulation device also includes a condenser that works in conjunction with the evaporator. The condenser transfers the heat absorbed by the evaporator to the external cooling medium (external cooling water → condenser inlet → after heat absorption → condenser outlet → back to the cooling tower), thus completing the circulation of the cooling medium. The refrigerant liquefies and releases heat in the condenser. By driving the refrigerant to circulate between the evaporator and condenser (such as in vapor compression refrigeration), the pressure and temperature of the refrigerant are increased, ensuring efficient heat transfer. An expansion valve is located between the evaporator and condenser, regulating the flow and pressure of the refrigerant, allowing the liquid refrigerant to rapidly evaporate and absorb heat in the evaporator. The cooled condensate is then transported back to the condensate coil 16 via the output of the liquid pump through the condensate inlet pipe 13, thus completing the cooling circulation of the condensate in the condensate coil 16.

[0027] like Figures 1-3As shown, a discharge pipe 21 is welded to the bottom of the cooling conveyor pipe 15 on the side away from the feed pipe 20. The bottom of the discharge pipe 21 is connected to a heat sink 12 via a flange. The catalyst, which has been preliminarily cooled by the cooling conveyor pipe 15, can enter the heat sink 12 through the discharge pipe 21. Guide blocks 23 are bolted to both sides of the inner wall of the heat sink 12. The guide blocks 23 are inclined and can guide the catalyst to flow along a preset path within the heat sink 12. A cooling fan 24 is bolted to the middle of the front wall of the heat sink 12, between the two guide blocks 23. A heat dissipation filter 22 is bolted to the rear wall of the heat sink 12, behind the cooling fan 24. The heat dissipation filter 22 filters the air entering the heat sink 12, preventing dust and other impurities from contaminating the catalyst. An interception net is installed behind the cooling fan 24. During operation, it can draw in outside air and filter it through the heat dissipation filter. After being filtered by the mesh 22, the airflow is directed towards the catalyst flowing through the heat dissipation box 12, providing secondary heat dissipation for the catalyst. The mesh prevents particulate solid catalyst from being carried out by the cooling fan 21. The cooling fan 21 can be set to a low airflow during operation to ensure that outside air can circulate into the heat dissipation box 12 and carry away the heat. A discharge pipe is installed at the bottom of the heat dissipation box 12, and the outlet of the discharge pipe corresponds to the upper surface of the feeding conveyor belt 2, so that the cooled catalyst can fall onto the feeding conveyor belt 2. A spiral conveying rod 18 is rotatably connected to the middle of the inner side wall of the cooling conveying pipe 15 through a bearing. A second servo motor 11 is fixedly installed on the side wall of any support frame 8 by bolts. The output end of the second servo motor 11 is fixedly connected to one end of the spiral conveying rod 18 through a coupling. When the second servo motor 11 is working, it can drive the spiral conveying rod 18 to rotate, thereby conveying the catalyst in the cooling conveying pipe 15 forward.

[0028] like Figures 1-2 As shown, a control panel 6 is fixedly installed on the side wall of the base 1 by bolts. The control panel 6 has a control circuit inside, which is electrically connected to the second servo motor 11, the first servo motor 4, the cooling fan 24 and the condensate cooling circulation device through wires, respectively. It can realize the start and stop control of these components and the adjustment of operating parameters, thereby realizing the overall control of the entire device.

[0029] It should be noted that when using this rapid cooling device, the operator first starts the device through the control panel 6. The condensate cooling circulation device starts working. The low-temperature condensate enters the condensate coil 16 through the condensate inlet pipe 13. During the flow in the condensate coil 16, it absorbs the heat from the high-temperature catalyst in the cooling conveying pipe 15, and its own temperature rises. Then it flows out from the condensate outlet pipe 14 and flows back to the condensate cooling circulation device. After cooling, it enters the condensate coil 16 again as low-temperature condensate, forming a circulation of condensate.

[0030] Meanwhile, the high-temperature catalyst is delivered to the inlet 10 through the feed pipe 20. The operator can adjust the opening of the throttle valve 19 through the control panel 6 to control the flow rate of the catalyst entering the cooling feed pipe 15. After the high-temperature catalyst enters the cooling feed pipe 15, the control panel 6 controls the second servo motor 11 to start. The second servo motor 11 drives the screw conveyor 18 to rotate. During the process of conveying the catalyst, the screw conveyor 18 makes the catalyst evenly distributed in the cooling feed pipe 15, increasing the contact area between the catalyst and the inner wall of the cooling feed pipe 15. This facilitates the transfer of the heat of the catalyst to the condensate in the condenser coil 16 through the cooling feed pipe 15, achieving the initial rapid cooling of the catalyst.

[0031] The catalyst, after initial cooling, is pushed by the screw conveyor 18 to the end of the cooling conveyor pipe 15 and enters the heat dissipation box 12 through the discharge pipe 21. Inside the heat dissipation box 12, the catalyst flows along a preset path under the guidance of two guide blocks 23. At this time, the control panel 6 controls the start of the cooling fan 24. The cooling fan 24 draws in outside air, and after the air passes through the heat dissipation filter 22 to remove dust and other impurities, it is blown onto the flowing catalyst to perform secondary heat dissipation on the catalyst and further reduce the temperature of the catalyst. The cooled air is discharged from other openings of the heat dissipation box 12.

[0032] After the catalyst has been cooled by secondary heat dissipation, it falls onto the feeding conveyor belt 2 through the discharge pipe at the bottom of the heat dissipation box 12. The control panel 6 controls the first servo motor 4 to start. The first servo motor 4 drives the transmission roller on the feeding conveyor belt 2 to rotate through the transmission component 3, thereby driving the feeding conveyor belt 2 to run and transport the cooled catalyst into the collection box 7, completing the entire catalyst cooling and collection process.

[0033] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
