Description

Technical Field

[0001] The present invention relates to the field of drying equipment, in particular to drying equipment for producing catalysts using an impregnation method. Background Art

[0002] A catalyst is a substance that can accelerate the rate of a chemical reaction without being consumed or changed during the reaction. It makes the reaction more efficient by reducing the activation energy of the reaction. The catalyst can participate in the reaction at the beginning of the reaction to form an intermediate product, but after the reaction is over, it will return to its original state and can continue to participate in the next round of reaction. The impregnation method for producing catalysts is a common catalyst preparation method that is widely used in the production of catalysts, especially in the preparation of metal catalysts. Through this method, a metal precursor solution is impregnated into the surface of the carrier, thereby loading the active component (usually a metal or metal compound) onto the catalyst carrier. After the catalyst is produced by the impregnation method, a drying device needs to be used for drying.

[0003] Commonly used drying devices include double-cone rotary vacuum dryers. When the double-cone rotary vacuum dryer is drying, the material enters the double-cone rotary vacuum dryer through the feed port. Then the double-cone rotary vacuum dryer rotates, and the material inside will turn over inside it and then be dried. The vacuum pump, double-cone rotary vacuum dryer and internal separator work together to separate the liquid in the material to achieve the purpose of drying.

[0004] However, when the existing double-cone rotary vacuum dryer rotates, the material will enter the feed port. When the double-cone rotary vacuum dryer starts working, the temperature inside the feed port is low and the heating efficiency is also low. It takes a long time for the heat to be transferred to the feed port. The material entering the feed port will result in poor drying effect and reduce the drying efficiency. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a drying device for producing catalysts using an impregnation method to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: A drying device for producing catalysts using an impregnation method, comprising a dryer body, a feed port being provided at the top of the dryer body, and a discharge port being provided at the bottom of the dryer body, a limit cover being threadedly installed on the top of the feed port, a plurality of cross bars being fixed to the inner wall of the feed port, and a limit plate being fixed to the end of the cross bar, a threaded hole being provided inside the limit plate, a screw being movably installed on the inner wall of the threaded hole, and a limit block being movably installed on the end of the screw, a plurality of vertical bars being fixed on the top of the limit block, a limit rod being movably installed inside the screw, and a spring being fixed to the bottom of the limit rod, and a slot being provided inside the limit cover.

[0007] By adopting the above technical solution, the problem that the material of the existing dryer body easily enters the inner wall of the feed port during operation is solved. The limit block is arranged to fit with the top of the inner wall of the dryer body, thereby preventing the material from entering the inner wall of the feed port, and the limit block made of beryllium copper alloy contacts the top of the inner wall of the dryer body, heat is transferred to the limit block, and the bottom of the limit block contacts the material, while also drying the material. In addition, the limit block can protect the separator. When the material enters the dryer from the feed port, the limit block can prevent the material from hitting the separator. When the material enters the dryer body, it will be scattered outward under the action of the conical limit block, preventing the material from falling vertically and hitting the separator, thereby protecting the separator and preventing the separator from being deformed by the falling material during long-term operation, thereby causing damage to the separator. The limit cover is connected to the dryer body by threads, replacing the traditional flange connection method, making the limit cover more convenient to disassemble.

[0008] The present invention is further configured such that a sliding groove is provided inside the screw rod, and the bottom end of the inner wall of the sliding groove is connected to the spring.

[0009] Preferably, the limit rod can be limited by the provided sliding groove so that the limit rod can only slide on the inner wall thereof, and the limit rod is accommodated, and the limit rod will compress the spring when sliding inside.

[0010] The present invention is further configured such that the end of the limiting rod is provided with an inclined surface, the limiting rod is provided with a polygonal shape, and the inner wall of the slot is provided with an inclined surface.

[0011] Preferably, the setting of the inclined surface enables the limiting rod to better enter the interior of the slot.

[0012] The present invention is further configured such that the inner wall of the feed port can also be installed with multiple sets of fixed pulleys, and two sets of cross bars are fixed to the inner wall of the feed port, the outer wall of the fixed pulley is provided with a pull rope, and one end of the pull rope is fixed with a connecting rod, and the other end of the pull rope is fixed with a limiting block, and an extrusion rod is fixed inside the limiting cover, the connecting rod is configured to be cross-shaped, and the length of the connecting rod is smaller than the diameter of the inner wall of the feed port.

[0013] Preferably, when in use, tightening the limit cover will squeeze the connecting rod, and the connecting rod moving downward will pull the pull rope, and the other end of the pull rope will pull the limit block upward, so that the limit block contacts the top of the inner wall of the dryer body, instead of tightening the screw to drive the limit block to move upward. There is no need to align the limit rod with the slot, and the limit cover can be directly installed, making the installation of the limit cover more convenient.

[0014] The present invention is further configured such that protrusions are fixed on both sides of the horizontal rod, and through holes are opened inside the protrusions, and the inner walls of the through holes are in contact with the outer walls of the vertical rods.

[0015] Preferably, the vertical rod and the through hole cooperate with each other to limit the movement direction of the limit block, so that the limit block can only move up and down.

[0016] The present invention is further configured such that the end of the extrusion rod is spherically configured, and the tops of the cross bar and the limiting plate are both inclined.

[0017] Preferably, when the limiting cover rotates, the extrusion rod is driven to rotate, and the spherical extrusion rod can reduce the friction between the extrusion rod and the connecting rod.

[0018] The present invention is further configured such that a plurality of inclined plates are fixed to the inner wall of the feed port, and the inclined plates are located above the fixed pulley, and the width of the inclined plates is greater than the width of the fixed pulley.

[0019] Preferably, the inclined plate is provided to guide the falling material to prevent the material from falling to the side of the fixed pulley close to the inner wall of the feed port.

[0020] The present invention is further configured such that a first fixing block is fixed to the end of the vertical rod, and a second fixing block is fixed to the outer wall of the vertical rod, and the diameters of the second fixing block and the first fixing block are both larger than the vertical rod.

[0021] Preferably, the second fixing block and the first fixing block are provided to limit the movement distance of the vertical rod, and under the action of the first fixing block, the limiting block can be prevented from moving downward.

[0022] The present invention is further configured such that the top of the limit block is conical, the outer wall of the limit block is in contact with the top of the inner wall of the dryer body, and the material of the limit block is beryllium copper alloy.

[0023] Preferably, the conical setting of the top of the limit block prevents the material from accumulating on the top of the limit block when it falls, which can better guide the material. The outer wall of the limit block fits with the top of the inner wall of the dryer body, which can prevent the material from entering the inside of the feed port during drying. The limit block made of beryllium copper alloy is not only hard and not easy to deform, but also has good thermal conductivity, which can dry the material in contact with it.

[0024] The present invention is further configured such that a plurality of connection blocks are fixed to the outer wall of the limiting cover.

[0025] Preferably, the provided connecting block enables the user to conveniently rotate the limit cover and tighten the limit cover.

The limit block made of beryllium copper alloy contacts the top of the inner wall of the dryer body, heat is transferred to the limit block, and the bottom of the limit block contacts the material, while drying the material. The limit block can protect the separator. When the material enters the dryer from the feed port, the limit block can prevent the material from hitting the separator. When the material enters the dryer body, it will be scattered outward under the action of the conical limit block, preventing the material from falling vertically and hitting the separator, thereby protecting the separator and preventing the separator from being deformed by falling during long-term operation, thereby causing damage to the separator. The limit cover is connected to the dryer body by a thread, replacing the traditional flange connection method, making the limit cover more convenient to disassemble.

[0028] The present invention is provided with a fixed pulley, a cross bar, a connecting rod, an extrusion rod, a pull rope and a limit block. When in use, tightening the limit cover will squeeze the connecting rod, and the connecting rod moving downward will pull the pull rope, and the other end of the pull rope will pull the limit block upward, so that the limit block contacts the top of the inner wall of the dryer body, replacing the method of tightening the screw to drive the limit block to move upward.

[0047] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0048] The following describes an embodiment of the present invention based on its overall structure.

[0049] Example 1: Please refer to Figures 1-9, including a dryer body 1, a feed port 2 is provided on the top of the dryer body 1, an upper cover 4 is installed on the top of the feed port 2 through a flange, and a discharge port 3 is provided at the bottom of the dryer body 1, a limit cover 5 is installed on the top of the feed port 2 through a thread, a plurality of groups of cross bars 81 are fixed to the inner wall of the feed port 2, and a limit plate 8 is fixed at the end of the cross bar 81, a threaded hole 82 is opened inside the limit plate 8, a separator 7 is provided inside the dryer body 1, and a screw 61 is movably installed on the inner wall of the threaded hole 82, and a limit block 6 is movably installed on the end of the screw 61, a plurality of groups of vertical rods 63 are fixed on the top of the limit block 6, a limit rod 62 is movably installed inside the screw 61, and the limit rod A spring 67 is fixed to the bottom of 62, and a slot 51 is provided inside the limit cover 5. When the limit cover 5 is rotated, the limit cover 5 is threadedly connected to the outer wall of the feed port 2, and the limit cover 5 moves downward on the outer wall of the feed port 2. When the limit cover 5 rotates, the limit rod 62 is driven to rotate at the same time, and when the limit rod 62 rotates, the screw 61 is driven to rotate. According to the screw principle, the screw 61 rotates, and the limit plate 8 and the cross bar 81 are fixed. Therefore, the screw 61 will move upward inside the limit plate 8, and when the screw 61 moves upward, it will drive the limit block 6 to move upward. When the limit block 6 moves to the top of the inner wall of the dryer body 1, the outer wall of the limit block 6 contacts the top of the inner wall of the dryer body 1, and the rotation of the limit cover 5 stops.

[0050] In the above embodiment, please refer to Figure 7 A sliding groove 66 is provided inside the screw 61, and the bottom end of the inner wall of the sliding groove 66 is connected to the spring 67. The sliding groove 66 can limit the limit rod 62 so that the limit rod 62 can only slide on its inner wall. The limit rod 62 is stored and the limit rod 62 will squeeze the spring 67 when sliding inside.

[0051] In the above embodiment, please refer to Figure 6 and Figure 9 The end of the limiting rod 62 is provided with an inclined surface, and the limiting rod 62 is provided with a polygonal shape, and the inner wall of the slot 51 is provided with an inclined surface. The setting of the inclined surface enables the limiting rod 62 to better enter the interior of the slot 51.

[0052] In the above embodiment, please refer to Figure 5 and Figure 6 The top of the limit block 6 is conical, and the outer wall of the limit block 6 fits with the top of the inner wall of the dryer body 1, and the material is beryllium copper alloy. The conical setting of the top of the limit block 6 prevents the material from accumulating on the top of the limit block 6 when the material falls, and can better guide the material. The outer wall of the limit block 6 fits with the top of the inner wall of the dryer body 1 to prevent the material from entering the inside of the feed port 2 during drying. The limit block 6 made of beryllium copper alloy is not only hard and not easy to deform, but also has good thermal conductivity, and can dry the material in contact with it.

[0053] In the above embodiment, please refer to Figure 2 and Figure 9 The outer wall of the limit cover 5 is fixed with multiple groups of connecting blocks 53. The provided connecting blocks 53 enable the user to conveniently rotate the limit cover 5 and tighten the limit cover 5.

[0054] Example 2: Please refer to Figures 10-16 The inner wall of the feed port 2 can also be equipped with multiple sets of fixed pulleys 9, and two sets of cross bars 81 are fixed to the inner wall of the feed port 2. The outer wall of the fixed pulley 9 is provided with a pull rope 92, and one end of the pull rope 92 is fixed with a connecting rod 91, and the other end of the pull rope 92 is fixed to the limit block 6. The top of the limit block 6 is fixed with multiple sets of vertical rods 63. The inside of the limit cover 5 is fixed with an extrusion rod 52, and the connecting rod 91 is arranged in a cross shape, and the length of the connecting rod 91 is smaller than the diameter of the inner wall of the feed port 2. The bottom of the connecting rod 91 will contact the bottom of the fixed pulley 9 to prevent the connecting rod 91 from moving upward again. When the limit cover 5 is tightened to the outer wall of the feed port 2, the limit cover 5 will move downward, and the extrusion rod 52 inside the limit rod 5 will squeeze the connecting rod 91 to move downward. The downward movement of the connecting rod 91 will pull one end of the pull rope 92 downward, and the other end of the pull rope 92 will pull the limit block 6 upward.

[0055] In the above embodiment, please refer to Figure 11-14 There are multiple groups of vertical rods 63 fixed on the top of the limit block 6, and protrusions 83 are fixed on both sides of the cross bar 81. A through hole 84 is opened inside the protrusion 83, and the inner wall of the through hole 84 fits with the outer wall of the vertical rod 63. The vertical rod 63 and the through hole 84 cooperate with each other to limit the movement direction of the limit block 6, so that the limit block 6 can only move up and down.

[0056] In the above embodiment, please refer to Figure 15 The end of the extrusion rod 52 is spherically set, and the top of the cross bar 81 and the limit plate 8 are both inclined. When the limit cover 5 rotates, the extrusion rod 52 will be driven to rotate. The spherical setting of the extrusion rod 52 can reduce the friction between it and the connecting rod 91.

[0057] In the above embodiment, please refer to Figure 12 , multiple sets of inclined plates 93 are fixed to the inner wall of the feed port 2, and the inclined plates 93 are located above the fixed pulley 9, and the width of the inclined plates 93 is greater than the width of the fixed pulley 9. The inclined plates 93 can guide the falling materials to prevent them from falling to the side of the fixed pulley 9 close to the inner wall of the feed port 2.

[0058] In the above embodiment, please refer to Figure 16A first fixing block 64 is fixed to the end of the vertical rod 63, and a second fixing block 65 is fixed to the outer wall of the vertical rod 63, and the diameters of the second fixing block 65 and the first fixing block 64 are both larger than the vertical rod 63. The second fixing block 65 and the first fixing block 64 are set to limit the movement distance of the vertical rod 63. Under the action of the first fixing block 64, the limit block 6 can be prevented from moving downward.

[0059] During the specific operation of the present invention: one side of the dryer body 1 is connected to the heat source pipe and the condensation pipe, and the other side is connected to the vacuum pump. Then, the material is added to the inside of the dryer body 1, and the material enters the inside of the dryer body 1 through the feed port 2. Under the action of the limit block, the logistics will fall on the top of the limit block 6. Due to the conical setting of the top of the limit block 6, the material is dispersed back to the surroundings. However, under the action of the limit block 6, the material will not hit the separator 7 below it when it falls. When the material is added, the limit cover 5 is installed. When the limit cover 5 is installed, the limit cover 5 will first squeeze the limit rod 62, and the limit rod 62 will slide on the inner wall of the slide 66. When the limit rod 62 slides, it will squeeze the spring 67, and then slowly rotate the limit cover 5. At this time, a knocking sound will be heard, and when the spring 67 Under the action, the limiting rod 62 enters the inner wall of the slot 51, and then aligns the limiting cover 5 with the outer wall of the feed port 2, rotates the limiting cover 5, and the limiting cover 5 is threadedly connected to the outer wall of the feed port 2, and the limiting cover 5 moves downward on the outer wall of the feed port 2. When the limiting cover 5 rotates, it also drives the limiting rod 62 to rotate, and when the limiting rod 62 rotates, it drives the screw 61 to rotate. According to the screw principle, the screw 61 rotates, and the limiting plate 8 and the cross bar 81 are fixed, so the screw 61 will move upward inside the limiting plate 8, and when the screw 61 moves upward, it will drive the limiting block 6 to move upward. When the limiting block 6 moves to the top of the inner wall of the dryer body 1, the outer wall of the limiting block 6 contacts the top of the inner wall of the dryer body 1, and then the motor on one side of the dryer body 1 is started, and the motor drives the dryer body 1 to rotate;

[0060] Hot water flows into the heat source pipe on one side of the dryer body 1, enters the interior of the dryer body 1, heats the dryer body 1, and then flows into the condensation pipe after passing through the interior of the dryer body 1. The vacuum pump on the other side of the dryer body 1 works to extract the liquid inside the dryer body 1. The liquid and particulate matter are separated by the action of the separator 7. After drying is completed, the dryer body 1 stops rotating, the vacuum pump also stops working, and hot water no longer flows into the interior of the dryer body 1.

[0061] The butterfly valve at the bottom of the discharge port 3 is opened to discharge the material inside the dryer body 1, and then the limit cover 5 is rotated. The reverse rotation of the limit cover 5 will drive the limit rod 62 to rotate, and the rotation of the limit rod 62 will drive the screw 61 to rotate. According to the screw principle, the screw 61 will move downward when it rotates. When the screw 61 moves downward, it will drive the limit block 6 away from the discharge port 3, and then separate the limit rod 5 from the discharge port 3.

[0062] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiment without creative contribution as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
