[0002] The effect caused by a catalyst in a chemical reaction is called catalysis, and the catalyst carrier is also called a support. It is one of the components of a supported catalyst and is the skeleton of the active components of the catalyst. It supports the active components and disperses them. It can also increase the strength of the catalyst. Catalysts and their carriers are widely used, such as in exhaust purification devices on various fuel vehicles.

[0003] The existing application number is: 202221903522.9, which is a honeycomb structure fly ash catalyst ceramic carrier, including a carrier body, the carrier body including a first carrier component and a second carrier component, the first carrier component is located on the top of the second carrier component, and the top of the first carrier component and the second carrier component are both provided with a plurality of first mounting grooves, and the plurality of first mounting grooves are evenly spaced, and the bottom of the first carrier component and the second carrier component are both provided with a plurality of second mounting grooves.

[0004] When the above technology is in use, although it makes it easy for personnel to clean and maintain the catalyst carrier by splitting the carrier body into a first carrier assembly and a second carrier assembly, it does not have a corresponding debris collection component, that is, it is impossible to collect the broken catalyst carrier, resulting in the broken carrier debris moving to subsequent parts of the equipment, thereby affecting the recovery of the debris by personnel during subsequent maintenance; therefore, in order to solve the above technical problems, we proposed a honeycomb ceramic catalyst carrier. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a honeycomb ceramic catalyst carrier.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A honeycomb ceramic catalyst carrier comprises a cross-shaped mounting frame, wherein a corresponding mounting box is arranged between each end of the mounting frame, a carrier body is arranged inside the mounting box, one end of the mounting box is in an open state and is provided with a sealing plate, the other end of the mounting box and the plate body of the sealing plate are provided with a plurality of flow holes, a plurality of limit grooves are arranged on both sides of each end of the mounting frame, a limit strip is slidably inserted in the limit groove, and one side of the limit strip is fixed to the outer wall of the mounting box.

[0008] Preferably, the four corners of the sealing plate are connected to the mounting box by screws, and the distribution of the flow holes corresponds to the holes on the carrier body.

[0009] Preferably, the mounting frame is provided with a rod-shaped mounting protrusion in the middle of one end of the sealing plate, the rod body of the mounting protrusion is clamped with a limiting frame through a nut, and the mounting frame and the sealing plate are provided with matching accommodating grooves at each end of the limiting frame.

[0010] Preferably, two side surfaces of the installation box away from the installation frame are provided with installation grooves, and heat conducting sheets are installed in the installation grooves.

[0011] Preferably, the four sides of the inner ring surface of the installation box are rounded, and the sides of the outer ring surface of the carrier body are rounded corresponding to the inner ring surface of the installation box.

[0012] Preferably, a stabilizing plate is provided at one end of the mounting frame away from the sealing plate, and matching air inlets are provided at four corners of the stabilizing plate corresponding to the flow holes on the four mounting boxes.

[0013] Preferably, the middle portion of the stabilizing plate is connected to the mounting frame by bolts, a plurality of limiting rods are provided on the side of the stabilizing plate facing the mounting frame, and one end of the limiting rod away from the stabilizing plate is inserted into the mounting frame.

[0014] The utility model provides a honeycomb ceramic catalyst carrier, which has the following beneficial effects:

[0015] 1: In the utility model, the catalyst carrier is divided into several relatively independent individuals by setting the installation box, the sealing plate and the flow hole. Then, when the catalyst carrier is broken or damaged during use, the personnel can replace the damaged carrier separately, thereby avoiding the waste of resources and the economic loss of personnel when replacing the entire catalyst carrier. Moreover, because the installation box and the sealing plate form a whole, when each carrier body is broken or damaged, the debris will not flow along the flow of the exhaust gas to the subsequent parts of the equipment, that is, the debris is collected in the installation box, so that the personnel can conveniently collect the debris of the carrier body when they repair it at a later time.

[0016] 2: The provision of screws in the utility model makes it easy for personnel to disassemble and install the sealing plate, and then to replace and clean the carrier body inside the installation box accordingly. Since the flow holes correspond to the holes on the carrier body, it is easy to avoid interference between the installation box and the sealing plate on the gas flowability of the carrier body, thereby ensuring the smooth flow of exhaust gas from the carrier body. The provision of the limit frame makes it easy to fix and limit each installation box, that is, when each installation box is slidably installed on the inner side of each end of the installation frame, the personnel fix the limit frame to the end of the installation frame through the nut. At this time, the limit frame blocks the installation box to prevent the installation box from sliding out of the installation frame, thereby improving the stability of the installation box when in use.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Example 1

[0027] Reference Figure 1-7 A honeycomb ceramic catalyst carrier comprises a cross-shaped mounting frame 1, a corresponding mounting box 2 is arranged between each end of the mounting frame 1, a carrier body 3 is arranged inside the mounting box 2, one end of the mounting box 2 is in an open state and is provided with a sealing plate 4, the other end of the mounting box 2 and the sealing plate 4 are provided with a plurality of flow holes 5, a plurality of limiting grooves 6 are arranged on both sides of each end of the mounting frame 1, a limiting strip 7 is slidably inserted in the limiting groove 6, and one side of the limiting strip 7 is fixed to the outer wall of the mounting box 2.

[0028] Example 2

[0029] Reference Figure 1-7 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0030] The four corners of the sealing plate 4 are connected to the mounting box 2 by screws, and the distribution of the flow holes 5 corresponds to the holes on the carrier body 3. The setting of the screws makes it easy for personnel to disassemble and install the sealing plate 4, and then to replace and clean the carrier body 3 inside the mounting box 2 accordingly. Since the flow holes 5 correspond to the holes on the carrier body 3, it is easy to avoid interference between the mounting box 2 and the sealing plate 4 on the gas flowability of the carrier body 3, that is, to ensure the smooth flow of exhaust gas from the carrier body 3; the mounting frame 1 is provided with a rod-shaped mounting protrusion 8 in the middle of one end of the sealing plate 4, and a limiting frame 9 is clamped on the rod body of the mounting protrusion 8 by a nut, and the mounting frame 1 and the sealing plate 4 are provided with matching accommodating members at each end of the limiting frame 9. The arrangement of the groove and the limit frame 9 facilitates the fixed limit of each installation box 2, that is, when each installation box 2 is slidably installed on the inner side of each end of the installation frame 1, the personnel fix the limit frame 9 to the end of the installation frame 1 through a nut. At this time, the limit frame 9 blocks the installation box 2 to prevent the installation box 2 from sliding out of the installation frame 1, thereby improving the stability of the installation box 2 during use; the two sides of the installation box 2 away from the installation frame 1 are provided with installation grooves, and heat conducting plates 10 are installed in the installation grooves. The arrangement of the heat conducting plates 10 facilitates the heat dissipation of the installation box 2, that is, when the heat in the exhaust gas is transferred to the carrier body 3, it is diffused to the external components through the installation box 2 and the heat conducting plate 10, thereby reducing the temperature of the carrier body 3 to prevent the carrier body 3 from being damaged by high-temperature sintering.

[0031] The four sides of the inner ring surface of the installation box 2 are rounded, and the outer ring surface of the carrier body 3 has matching rounded corners corresponding to the inner ring surface of the installation box 2. The setting of each rounded corner improves the strength of the installation box 2 and the carrier body 3, that is, improves the stability of the two when in use; the end of the mounting frame 1 away from the sealing plate 4 is provided with a stabilizing plate 11, and the four corners of the stabilizing plate 11 are provided with matching air inlets 12 corresponding to the flow holes 5 on the four mounting boxes 2. The setting of the stabilizing plate 11 and the air inlet 12 allows the catalyst to purify the exhaust gas, that is, the exhaust gas passes through the carrier body 3, the exhaust gas can flow directly to the flow hole 5 through the restriction of each air inlet 12, that is, the exhaust gas can flow to the carrier body 3 conveniently; the middle part of the stabilizing plate 11 is connected to the mounting frame 1 by a bolt 13, and a plurality of limiting rods 14 are provided on the side of the stabilizing plate 11 facing the mounting frame 1, and the end of the limiting rod 14 away from the stabilizing plate 11 is inserted into the mounting frame 1. The setting of the bolt 13 is convenient for personnel to fix the stabilizing plate 11, and the setting of the limiting rod 14 is convenient for providing limiting and positioning effects when the stabilizing plate 11 is fixed.

[0032] Principle and advantages of use: During use of the utility model, first install each carrier body 3 in each installation box 2, and then slide and insert each installation box 2 into the inner side of each end of the installation frame 1. At this time, the catalyst carrier is assembled, that is, the personnel can install this carrier in the external exhaust gas purification device, and then the exhaust gas from the external equipment enters the installation box 2 through the flow hole 5 from the end of the installation box 2 away from the sealing plate 4, and then moves to the sealing plate 4 through the holes in the carrier body 3, and finally flows out from the flow hole 5 at the sealing plate 4. In this process, the exhaust gas reacts with the catalyst in the carrier body 3, thereby realizing the purification of the exhaust gas.

[0033] In the above process, since the four carrier bodies 3 together form a complete catalyst carrier, the catalyst carrier has a certain degree of modular energy supply, that is, when a part of the catalyst carrier is damaged, the personnel can replace the damaged part in a targeted manner. For example, when one of the carrier bodies 3 is damaged, the mounting box 2 at the damaged carrier body 3 can be directly taken out from the inside of the mounting frame 1. Compared with the traditional scheme in which the entire catalyst carrier needs to be replaced after a part of the carrier is damaged, when this scheme is used, only the damaged part of the carrier needs to be replaced in a targeted manner. That is, when this scheme is used, the utilization rate of resources can be effectively improved and the economic loss of personnel can be reduced. Moreover, since the sealing plate 4 and the mounting box 2 form a relatively sealed box body, when the carrier body 3 in the mounting box 2 is damaged and broken, the broken debris is collected in the mounting box 2, which can prevent the debris from flowing toward the The debris can flow to subsequent parts of external equipment, which is not only convenient for personnel to collect it later, but also the fragments of the carrier body 3 collected in the installation box 2 can continue to purify the exhaust gas to a certain extent. In summary, during the use of this scheme, through the setting of the installation box 2, the sealing plate 4 and the flow hole 5, the catalyst carrier is divided into several relatively independent individuals, and then when the catalyst carrier is broken and damaged during use, the personnel can replace the damaged carrier separately, thereby avoiding the waste of resources and economic losses of personnel when replacing the entire catalyst carrier, and because the installation box 2 and the sealing plate 4 form a whole, when each carrier body 3 is broken and damaged, the debris will not flow along the flow of exhaust gas to the subsequent parts of the equipment, that is, the debris is collected in the installation box 2, so that when the personnel perform maintenance on it in the later stage, the debris of the carrier body 3 can be conveniently collected.

[0034] It should be further explained that, through the provision of screws, it is convenient for personnel to disassemble and install the sealing plate 4, and then it is convenient to replace and clean the carrier body 3 inside the installation box 2 accordingly. Since the flow hole 5 corresponds to the hole on the carrier body 3, it is convenient to avoid interference between the installation box 2 and the sealing plate 4 on the gas flow of the carrier body 3, that is, to ensure the smooth flow of exhaust gas from the carrier body 3; the provision of the limit frame 9 is convenient for fixing and limiting each installation box 2, that is, when each installation box 2 is slidably installed on the inner side of each end of the installation frame 1, the personnel use the nut to limit the limit The positioning frame 9 is fixed at the end of the mounting frame 1. At this time, the limiting frame 9 blocks the mounting box 2 to prevent the mounting box 2 from sliding out of the mounting frame 1, thereby improving the stability of the mounting box 2 when in use; the setting of the heat conducting sheet 10 facilitates the heat dissipation of the mounting box 2, that is, when the heat in the exhaust gas is transferred to the carrier body 3, it is diffused to the external components through the mounting box 2 and the heat conducting sheet 10, thereby reducing the temperature of the carrier body 3 to prevent the carrier body 3 from being damaged by high-temperature sintering; the setting of each rounded corner improves the strength of the mounting box 2 and the carrier body 3, that is, improves the stability of both when in use.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
