Description

Technical Field

[0001] The present invention mainly relates to the technical field related to the detection and processing of honeycomb ceramic carriers, and specifically relates to a device and method for purging moisture from a honeycomb ceramic carrier sample. Background Art

[0002] Honeycomb ceramics are a new type of porous structural ceramics with an internal structure similar to a honeycomb shape. By dispersing the active components of the catalyst on the surface of the honeycomb ceramic carrier, a higher surface area is obtained to improve the catalytic efficiency. At present, it has been widely used in the fields of automobile exhaust purification and industrial harmful gas treatment. Among them, water absorption is a key indicator of the honeycomb ceramic carrier, which is related to the stability of the catalyst coated on the carrier. The appropriate water absorption can prevent the catalyst from falling off and improve the exhaust gas treatment efficiency. Therefore, it is very important to accurately and efficiently detect the water absorption of the carrier.

[0003] At present, when testing the water absorption rate of carrier samples, it is necessary to soak the samples in water and then weigh them to calculate the water absorption rate of the measured carrier. In order to improve accuracy and reduce errors, the water remaining on the surface and pores of the samples needs to be blown away before weighing. In the prior art, the water purge of samples is mostly done by manual air guns. However, the manual air gun purge method has different blowing strength and direction each time, resulting in large differences in repeated test results of the same sample. The efficiency and stability of water purge are difficult to guarantee, which increases the cost of production management and quality control. On the other hand, manual purge is difficult to standardize. In the prior art, traditional automatic purge equipment can generally only purge one surface of the sample, while honeycomb carrier samples need to purge not only the surface but also the internal pores. When the traditional purge structure is applied to the purge of honeycomb carrier samples, it is not only inefficient, but also difficult to guarantee the water purge effect in the pores.

[0004] Therefore, in order to achieve high efficiency and high stability in water absorption detection and meet the requirements of catalyst coating, it is necessary to design a device that can achieve standardized moisture purging of carrier samples. Summary of the invention

[0005] In order to solve the shortcomings of the current technology, the present invention combines the existing technology and provides a honeycomb ceramic carrier sample moisture purging device and method from the perspective of practical application. This technology can realize a standardized solution for purging moisture on the surface and pores of carrier samples. Compared with the traditional manual air gun purging, the equipment uses automation technology to realize automatic sample clamping, equal pressure and equal distance purging of sample moisture, greatly improving the moisture purging efficiency and purging stability, reducing the labor intensity of workers, and enhancing the reliability of water absorption test results. On the other hand, the standardized water absorption test process promotes the quality and stability of the subsequent carrier coating catalyst.

The middle side of the equipment frame 1 is the equipment bottom plate 12, where the buttons of the operating table 4 are installed. The equipment bottom box 13 is located on the lower side of the equipment frame 1, and each control element in the control cabinet 5 is installed in the equipment bottom box 13.

[0041] refer to Figure 2 As shown. The support assembly of this embodiment mainly includes a rotating cylinder 25 and a sample support plate 26. A guide rod 22 is fixed on the bottom plate 12 of the equipment, and the rotating cylinder 25 is installed on the rotating cylinder bracket 21. One end of the rotating cylinder bracket 21 is installed on the guide rod 22. The installation position of the rotating cylinder bracket 21 on the guide rod 22 is adjustable, so that the height of the rotating cylinder 25 can be adjusted. The sample support plate 26 is fixedly connected to the cylinder rod of the rotating cylinder 25, and when the rotating cylinder 25 is actuated, it can drive the sample support plate 26 to rotate. Specifically, in the initial position, the sample support plate 26 is located directly above the square-to-round suction nozzle 35. In this state, the operator can directly place the carrier sample on the sample support plate 26 and then start the clamping assembly to clamp and fix the sample. After that, the rotating cylinder 25 is actuated to rotate the sample support part 26 by 90° to avoid the bottom of the sample, so as to leave space for subsequent moisture purge.

[0042] The clamping assembly 2 of this embodiment mainly includes a clamping cylinder 23, a top shaft 27, a clamping cylinder bracket 24, a top rod 28, and a top rod bracket 29. The clamping cylinder bracket 24 and the top rod bracket 29 are respectively fixed on both sides of the square-to-round suction nozzle 35, the top rod 28 is fixed on the top rod bracket 29, and the top shaft 27 is connected to the clamping cylinder 23. When the clamping cylinder 23 is actuated, the top shaft 27 is pushed to move toward the top rod 28, and then the sample located on the sample support plate 26 can be clamped and fixed by the top shaft 27 and the top rod 28. When the clamping cylinder 23 moves in the reverse direction, the top shaft 27 moves in the opposite direction to release the sample.

[0043] The purge assembly 3 of this embodiment is mainly arranged on the upper part of the clamping assembly 2. The purge assembly 3 is used to purge the sample from the top to the bottom. Under the purge action of the purge assembly 3, part of the moisture on the surface of the sample and in the pores evaporates quickly and disappears, and part of the moisture flows downward along the pores of the sample, and then the moisture is collected by the negative pressure suction assembly. In this embodiment, the purge assembly 3 mainly includes a telescopic cylinder 32, a telescopic cylinder bracket 31, a fan-shaped nozzle 34 and a nozzle bracket 33. The telescopic cylinder 32 is located at the upper end of the guide rod 22, and the two components are connected by the telescopic cylinder bracket 31.

Among them, the telescopic cylinder 32 can be adjusted up and down through the guide rod 22, and the fan-shaped nozzle 34 can be adjusted front and back through the movement of the telescopic cylinder 32, so as to achieve the purpose of uniform purge.

[0044] The negative pressure adsorption component of this embodiment is mainly used to perform negative pressure suction from the lower surface of the sample to collect moisture on the surface of the sample and in the pores. The negative pressure adsorption component mainly includes a square-to-round suction nozzle 35, which is located directly below the fan-shaped nozzle 34 and is locked on the device bottom plate 12 by a nut.

[0047] The working principle and use method of the sample moisture purging device of this embodiment are mainly as follows: when the device is in the preparation state, place the honeycomb ceramic carrier sample on the sample support plate 26, and ensure that the side of the sample is in contact with the top rod 28, press the start button 42 on the operating table 4, the device enters the running state, the clamping cylinder 23 drives the end top shaft 27 to extend and support the side of the sample, under the action of friction, it can cooperate with the top rod 28 on the other side to clamp the sample, and the rotating cylinder 25 drives the sample support plate 26 to rotate 90° counterclockwise to leave a working space for moisture purging. After that, the telescopic cylinder 32 drives the fan-shaped nozzle 34 to purge back and forth, and at the same time, the square-to-round suction nozzle 35 releases negative pressure to collect the purged moisture. After the purge is completed, the sample support plate 26 rotates and resets under the action of the rotating cylinder 25 to support the sample. Finally, the clamping cylinder 23 drives the top shaft 27 to retract, completing a purge operation cycle. The purge pressure and purge times can be set as standard values ​​in the control cabinet and the purge distance is fixed, thus achieving standardization of the purge equipment.

[0048] This embodiment not only greatly improves the efficiency and stability of the moisture purge of the carrier sample through automated operation, but also ensures the standardized operation of the entire process, which can overcome the problems of large differences in repeated test results and low operation efficiency during current manual operations. In addition, the equipment of the present invention has a compact structure and is easy to operate, which reduces the difficulty of operator training and greatly reduces the cost of testing. The present invention effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.
