Description

Technical Field

[0001] The invention relates to the technical field of CO-PROX catalyst coating, in particular to a CO-PROX integral catalyst coating machine. Background Art

[0002] CO-PROX monolithic catalyst is an important catalyst for reducing CO concentration. CO-PROX monolithic catalyst is evenly coated on a carrier using a coating machine, and the carrier has a honeycomb structure.

[0003] In the prior art, the honeycomb ceramic needs to be coated with a catalyst after being formed, and then the catalyst is evenly slurried; the catalyst coating of the honeycomb ceramic requires that all the honeycomb holes inside it be coated in place. In the prior art, it is usually completed by manual coating, which is very time-consuming and labor-intensive, and the internal honeycomb holes may not be coated in place, which is very troublesome. Utility Model Content

[0004] Purpose of the utility model: To address the deficiencies in the above-mentioned prior art and provide a CO-PROX integral catalyst coating machine.

[0005] Technical solution: In order to achieve the above-mentioned purpose of the utility model, the technical solution adopted by the utility model is as follows: a structure of a CO-PROX integral catalyst coating machine. The main components of the machine include: a driving cylinder (1), a driving plate (2), a vacuum circulation pipe (3), an upper mold mounting plate (4), an upper mold (5), an integral catalyst carrier (6), a lower mold (7), a frame (8), a control console (9), and a vacuum pump (10). Specifically, a driving cylinder (1) is arranged on the top of the coating machine body, a driving plate (2) is arranged at the bottom of the driving cylinder (1), and a control console (9) is arranged on the right side of the driving plate (2). A vacuum circulation pipe (3) is connected to the bottom of the driving plate (2), and the vacuum circulation pipe (3) is connected to the upper mold mounting plate (4). The upper mold (5) is attached to the bottom of the upper mold mounting plate (4), the integral catalyst carrier (6) is arranged below the upper mold (5), and the bottom of the integral catalyst carrier (6) is the lower mold (7). Below the lower mold (7) is a frame (8), and a vacuum pump (10) is installed inside the frame (8).

[0006] The driving cylinder is connected to the control device, the driving cylinder is directly connected to the driving plate, and the driving plate is connected to the upper mold mounting plate.

[0007] The upper mold and the lower mold can overlap to form a closed space.

[0008] Furthermore, there is a coating liquid at the bottom of the lower mold, and the lower mold is connected to the control device.

[0009] Furthermore, the vacuum circulation pipe is communicated with the upper mold, and the vacuum circulation pipe is connected to the vacuum pump inside the frame.

[0010] Compared with the prior art, the advantages of the present invention are:

[0011] (1) This device is different from the traditional catalyst coating method. This device is equipped with a driving cylinder to push the driving plate, which drives the upper mold mounting plate to press down, so that the upper and lower molds (there is a coating liquid tray at the bottom of the lower mold) are sealed with the two ends of the workpiece to form a sealed cavity with the small hole in the middle. Under the action of vacuum, the coating liquid at the bottom of the lower mold moves up to the other end of the honeycomb ceramic catalyst carrier (the residence time of the coating liquid on the carrier can be set so that the coating liquid is effectively coated on the inner hole surface of the honeycomb ceramic catalyst carrier)

[0012] (2) The coating liquid retention time is counted. When the time is up, the vacuum suction direction is switched so that the coating liquid moves downward and flows into the coating liquid receiving tray. The liquid receiving tray is automatically quantitatively added. The cylinder is driven to move upward to open the upper and lower molds. The coating work is automatically completed.

[0013] In order to clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of the utility model.
