Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a preparation device for an ozone catalytic oxidation composite catalyst. Background Technology

[0002] Ozone oxidation catalyst is a selective catalyst material that can alter the rate of ozone oxidation. Using high-quality activated carbon and alumina as carriers, this product can oxidize most organic matter, especially those substances that are difficult to biodegrade. It is widely used in advanced municipal wastewater treatment, nanofiltration and reverse osmosis concentrate treatment, and industrial wastewater pretreatment and advanced treatment. Current technologies require multiple sets of power devices to coordinate stirring, extrusion molding, and cutting during the preparation process, resulting in complex structures, inconvenient installation, increased energy consumption, and reduced production costs.

[0003] Existing technology CN222131797U discloses a composite catalyst preparation device for ozone catalytic oxidation of organic wastewater, comprising: a main unit including a base plate, two sets of support plates fixedly connected to the upper surface of the base plate, a mixing tank fixedly connected to the upper side of the support plates, a feed pipe fixedly connected to the upper side of the mixing tank, a controller installed on one side of one set of support plates, and a discharge cover fixedly connected to the end of the mixing tank away from the motor. This invention uses the controller to start the motor, driving the rotating shaft to rotate, so that the stirring rod on the surface of the spiral blades can squeeze and stir the material towards the discharge cover. The squeezed material is then discharged outward through a discharge groove on the surface of the discharge cover. Simultaneously, a drive ring is slowly rotated via a drive belt, and a connecting block fixedly connected to the drive ring drives a cutting plate to move on the surface of the discharge groove, thereby cutting the material discharged through the discharge groove into shape. This simplifies the structure and reduces energy consumption during production.

[0004] However, in actual processing and use, the materials will be in a viscous state when the above-mentioned equipment is stirred, so that they can be extruded and granulated. The above-mentioned equipment cannot perform rapid drying of the granulated products, which is not conducive to product shaping or transportation. Summary of the Invention

[0005] The purpose of this invention is to provide a preparation device for an ozone catalytic oxidation composite catalyst, which aims to achieve drying treatment of granulated products during catalyst preparation, thereby facilitating product shaping and subsequent transportation.

[0006] To achieve the above objectives, this utility model provides a preparation device for an ozone catalytic oxidation composite catalyst, including a preparation device body and a belt conveyor, wherein the belt conveyor is disposed below the discharge port of the preparation device body, and a drying mechanism is also included.

[0007] The drying mechanism includes a drying box, electric heating tubes, a fan, a perforated protective plate, and a leveling device. The drying box is fixed on the frame of the belt conveyor. Several electric heating tubes are installed in a row at intervals on the drying box. The fan is fixed on the top of the drying box and located above the electric heating tubes. The perforated protective plate is fixed on the top of the fan housing. The leveling device is located at the front end of the feeding side of the drying box.

[0008] The drying mechanism further includes baffles, which are detachably connected to the drying chamber and located on both sides of the drying chamber.

[0009] The leveling device includes a leveling plate and an adjusting assembly. The leveling plate is located above the conveyor belt of the belt conveyor, and the adjusting assembly is located on both sides of the leveling plate.

[0010] The adjustment assembly includes a first side plate and a second side plate. The first side plate is fixedly connected to the frame of the belt conveyor and slidably connected to the flat plate, and is located on one side of the belt conveyor. The second side plate is fixedly connected to the frame of the belt conveyor and slidably connected to the flat plate, and is located on the side of the belt conveyor away from the first side plate.

[0011] The ozone catalytic oxidation composite catalyst preparation equipment further includes a flipping mechanism, which includes a speed-regulating motor, a rotating shaft, and stirring rods. The speed-regulating motor is fixed to one side of the drying chamber. The rotating shaft is rotatably connected to the drying chamber and fixedly connected to the output shaft of the speed-regulating motor, and is located inside the drying chamber. Several stirring rods are screwed onto the rotating shaft and located on the upper side of the conveyor belt of the belt conveyor.

[0012] This invention relates to a preparation device for an ozone catalytic oxidation composite catalyst. During production, the device body performs granulation processing, and the granules fall onto the conveyor belt of a belt conveyor. Further, a leveling device can level the top surface of the granules to reduce the granule accumulation thickness. The granules continue to be conveyed to a drying chamber. At this time, several electric heating tubes that were turned on in advance before processing heat the air at the bottom of the blower, so that the air blown by the blower towards the catalyst granules has a certain temperature, thereby achieving the drying treatment of the catalyst. This allows for the drying treatment of the granulated product during catalyst preparation, which is beneficial for product shaping and subsequent transportation. Attached Figure Description

Detailed Implementation

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention. Example

[0020] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of the equipment for preparing ozone catalytic oxidation composite catalyst. Figure 2 This is a schematic diagram of the structure of the flat plate 108. This utility model provides a preparation device for an ozone catalytic oxidation composite catalyst: it includes a preparation device body 101, a belt conveyor 102, and a drying mechanism. The drying mechanism includes a drying chamber 103, an electric heating tube 104, a fan 105, a perforated protective plate 106, a baffle 107, and a leveling device. The leveling device includes a flat plate 108 and an adjusting assembly. The adjusting assembly includes a first side plate 109 and a second side plate 110. This solution enables the drying of granulated products during catalyst preparation, facilitating product shaping and subsequent transportation. It is understood that the aforementioned solution can dry granulated products, which is beneficial for product shaping and subsequent transportation.

[0021] In this embodiment, the belt conveyor 102 is located below the discharge port of the preparation equipment body 101. The granulation principle of the preparation equipment body 101 can adopt the existing granulation equipment structure, such as the prior art CN213194032U - a cyclone stirring device for a granulator, thereby realizing the granulation processing of the catalyst. The belt conveyor 102 is used for particle conveying.

[0022] The drying chamber 103 is fixed on the frame of the belt conveyor 102. Several electric heating tubes 104 are installed in a row on the drying chamber 103. The fan 105 is fixed on the top of the drying chamber 103 and located above the several electric heating tubes 104. The perforated protective plate 106 is fixed on the top of the housing of the fan 105. The leveling device is set at the front end of the feed side of the drying chamber 103. The drying chamber 103 is secured with bolts after being covered. Multiple electric heating tubes 104 are fixed to the drying chamber 103, with their heating parts having the same width as the inner cavity of the drying chamber 103. The housing of the fan 105 is fixed with bolts, and the perforated protective plate 106 is bolted to the top of the fan 105 for ventilation. Since the motor inside the fan 105 drives the fan blades to rotate, which is very dangerous, the perforated protective plate 106 provides safety protection. The leveling device is used for leveling when particles accumulate. A temperature sensor is installed on the inner wall of the drying chamber 103 for collecting internal temperature data and feeding it back to the equipment control system. Finally, the data can be displayed on the screen.

[0023] Secondly, the baffle 107 is detachably connected to the drying chamber 103 and is located on both sides of the drying chamber 103. The baffle 107 is fixed by bolts, and after installation, it will prevent hot air from being quickly discharged from the internal cavity of the drying chamber 103.

[0024] Then, the leveling plate 108 is positioned above the conveyor belt of the belt conveyor 102; the adjusting components are disposed on both sides of the leveling plate 108. The front side of the leveling plate 108 is provided with an inclined guide portion to facilitate leveling and fitting. The adjusting components are used to adjust the fitting distance between the leveling plate 108 and the conveyor belt of the belt conveyor 102, thereby facilitating the leveling of particle accumulations of different thicknesses.

[0025] Finally, the first side plate 109 is fixedly connected to the frame of the belt conveyor 102 and slidably connected to the flat plate 108, and is located on one side of the belt conveyor 102; the second side plate 110 is fixedly connected to the frame of the belt conveyor 102 and slidably connected to the flat plate 108, and is located on the side of the belt conveyor 102 away from the first side plate 109. The first side plate 109 and the second side plate 110 have the same dimensions and are both connected to the frame of the belt conveyor 102 by bolts arranged from bottom to top. Adjustment grooves are provided on the first side plate 109 and the second side plate 110 to facilitate the installation of mating round shafts on both sides of the flat plate 108. The outer side of the mating round shaft has an external thread end to facilitate the installation of locking nuts. The first side plate 109 and the second side plate 110 can also prevent particles from falling off the conveyor belt.

[0026] When using the granulated product of this utility model for drying treatment, which is beneficial for product shaping and subsequent transportation, granulation is carried out through the preparation equipment body 101 during production. Then, the granules fall onto the conveyor belt of the belt conveyor 102. Further, the top surface of the granules can be leveled by the leveling plate 108 to reduce the thickness of the granule accumulation, which is beneficial for subsequent uniform drying. The granules continue to be conveyed into the drying box 103. At this time, several electric heating tubes 104, which were turned on in advance before processing, heat the air at the bottom of the fan 105, so that the air blown by the fan 105 toward the catalyst granules will have a certain temperature, thereby achieving the drying treatment of the catalyst. The dried granules continue to be conveyed and finally fall into the receiving frame below the output side of the belt conveyor 102 for collection. Thus, the granulated product can be dried during catalyst preparation, which is beneficial for product shaping and subsequent transportation. Example

[0027] like Figure 3 and Figure 4 As shown, where Figure 3 yes, Figure 4 Yes, based on the first embodiment, this utility model provides a preparation device for an ozone catalytic oxidation composite catalyst, wherein the flipping mechanism includes a speed-regulating motor 201, a rotating shaft 202, and a stirring rod 203.

[0028] The variable speed motor 201 is fixed to one side of the drying chamber 103. The rotating shaft 202 is rotatably connected to the drying chamber 103 and fixedly connected to the output shaft of the variable speed motor 201, and is located inside the drying chamber 103. Several stirring rods 203 are screwed onto the rotating shaft 202 and located on the upper side of the conveyor belt of the belt conveyor 102. The fixing bracket of the variable speed motor 201 is fixed to the drying chamber 103 by bolts and is located in the middle of the drying chamber 103 after installation. The first side plate 109 and the second side plate 110 are provided with through holes to facilitate the passage of the rotating shaft 202. The stepped shafts on both sides of the rotating shaft 202 are installed on the drying chamber 103 through detachable bearing seats and rotating bearings. The side of the rotating shaft 202 closest to the output shaft of the variable speed motor 201 is connected to the output shaft of the variable speed motor 201 through a rigid coupling. The multiple stirring rods 203 are screwed onto the rotating shaft 202 and will not abut against the conveyor belt when rotating.

[0029] In this embodiment, when the flat plate 108 is adjusted upwards, the particle accumulation thickness will increase. At this time, during drying, the speed-regulating motor 201 can be controlled to rotate, driving the rotating shaft 202 and multiple stirring rods 203 to rotate. The stirring rods 203 will not rotate too fast to avoid particle splashing. The rotation speed of the stirring rods 203 can be adjusted by adjusting the speed of the speed-regulating motor 201, so that the particles can be turned over when the thickness is thick, which is convenient for uniform drying.

[0030] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application.
