Description

Technical Field

[0001] This utility model relates to the field of catalyst preparation sprayers, specifically a corrosion-resistant and pressure-resistant supported catalyst preparation sprayer. Background Technology

[0002] In the preparation of supported catalysts, the atomizer is a key piece of equipment, and its performance directly affects the uniform distribution of the catalyst and the preparation efficiency. Traditional atomizers have many shortcomings in nozzle flow control, making it difficult to meet the requirements of high-precision and high-efficiency catalyst preparation. Specifically, the nozzle flow control of traditional atomizers usually relies on manual adjustment or simple mechanical structures, which have disadvantages such as complex operation, low adjustment accuracy, and slow response speed. In the catalyst preparation process, since the catalyst flow rate is directly related to the uniformity and coverage area of ​​the spray, precise flow control is crucial to ensuring the quality of the catalyst. However, the limitations of traditional atomizers in flow control often lead to uneven catalyst spraying, or even local over- or under-exposure, which seriously affects the preparation effect and performance of the catalyst. To address this, we propose a corrosion-resistant and pressure-resistant atomizer for the preparation of supported catalysts. Utility Model Content

[0028] Structural Description: Mounting Plate 1: As a support structure for the sprayer, two sets of mounting plates 1 are arranged parallel to each other to fix and support the spray head 2 and its related components;

[0029] Spray head 2: Fixed between the two sets of mounting plates 1, it is the main component for catalyst spraying. A tail cap 12 is fixed to the tail end of the spray head 2 to seal the tail end of the spray head 2 and to communicate with the catalyst delivery pipe 13 to facilitate the input of catalyst;

[0030] Horizontal plate 3: Fixed between the two sets of mounting plates 1, corresponding to the position above the spray head 2. A miniature cylinder 4 is fixedly installed on the top of the horizontal plate 3 to provide driving force to adjust the flow rate of the spray head;

[0031] Miniature cylinder 4: Installed on top of horizontal plate 3, its piston rod slides out of the bottom of horizontal plate 3 and is fixedly connected to the top of movable crossbar 5. The start and stop of miniature cylinder 4 control the up and down sliding of flow control baffle 8;

[0032] The movable crossbar 5 is slidably installed between the inner grooves 6 opened on the adjacent sides of the two sets of mounting plates 1. When the piston rod of the micro cylinder 4 is pushed downward, the movable crossbar 5 slides downward through the inner groove 6 and compresses the connecting rod 7;

[0033] Inner groove 6: Opened on one side of the two sets of mounting plates 1 that are close to each other, used to guide and support the sliding of the moving crossbar 5;

[0034] Connecting rod 7: Its top end is fixedly connected to the bottom of the movable crossbar 5, and its bottom end is fixedly connected to the flow control baffle 8. Connecting rod 7 transmits the driving force of micro cylinder 4, causing the flow control baffle 8 to slide within the groove 14;

[0035] Flow control baffle 8: It is slidably connected within the groove 14 at the top of the spray head 2, and its two sides are tightly fitted with the inner walls of the groove 14. The up and down sliding of the flow control baffle 8 is used to block or open the delivery hole 11 on the flow plate 10, thereby adjusting the flow rate of the catalyst;

[0036] Connecting convex plate 9: It is fixed to both sides of the spray head 2 and is used to fix the spray head 2 to the side of the mounting plate 1 to enhance the stability of the spray head 2.

[0037] Flow plate 10: Fixed inside the spray head 2, adapted to the inner wall of the spray head 2. The flow plate 10 has several sets of conveying holes 11 arranged in a matrix and extending through both sides, for the spraying of catalyst;

[0038] Delivery holes 11: These are formed in a matrix on the flow plate 10. The catalyst is sprayed from the spray head 2 through the delivery holes 11. The sliding of the flow control baffle 8 can block or open these delivery holes 11 to regulate the flow rate;

[0040] Catalyst delivery pipe 13: Fixed to the back of the tail cap 12, communicating with the spray head 2. The catalyst is delivered into the spray head 2 through the catalyst delivery pipe 13;

[0041] Groove 14: Located on the top of the spray head 2, it guides and supports the sliding of the flow control baffle 8.

[0042] Working principle: In use, the catalyst is first delivered into the spray head 2 through the catalyst delivery pipe 13. The catalyst is then sprayed out of the spray head 2 through the delivery hole 11 on the flow plate 10. When it is necessary to adjust the flow rate of the catalyst delivered into the spray head 2, the micro cylinder 4 is activated. The piston rod on the micro cylinder 4 pushes the moving crossbar 5 downward. The moving crossbar 5 slides downward through the two sets of inner grooves 6 and squeezes the connecting rod 7. The flow control baffle 8 is squeezed by the connecting rod 7 and slides downward in the groove 14 on the spray head 2. The flow control baffle 8 blocks the delivery hole 11 on the flow plate 10, preventing the catalyst from being delivered out through the delivery hole 11. The flow rate is adjusted by the number of delivery holes 11 blocked by the flow control baffle 8. The more holes blocked, the smaller the discharge flow rate, and vice versa.
