Description

Technical Field

[0001] This utility model relates to the field of gas valve technology, specifically to a drying device for gas valves after painting. Background Technology

[0002] Gas valves are commonly used in gas transmission systems. To prevent gas valves from rusting, their surfaces are usually painted, and then dried.

[0003] Existing gas valve drying devices, as described in Chinese patent application publication number CN220027654U, involve hanging gas valves on hooks and then drying them while transporting them. During the drying process, hot air blows from top to bottom and cold air blows from bottom to top.

[0004] However, because the paint on the gas valves dries after spraying, it easily drips onto the fan below, causing paint splattering. After drying, the gas valves need to be removed from the hooks one by one, which is inefficient. Utility Model Content

[0005] The purpose of this invention is to provide a drying device for gas valves after painting, which can prevent paint splattering and facilitate the quick collection of dried gas valves.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0007] A drying device for gas valves after painting includes a drying chamber with an inlet and an outlet. A conveyor belt runs through both ends of the drying chamber. Positioning rods for inserting into gas valves are provided on the surface of the conveyor belt. The conveyor belt transports the gas valves, placed on the positioning rods, from the inlet to the outlet. A drying structure is located above the conveyor belt, and a collection trough is located below the section of the conveyor belt outside the outlet of the drying chamber. Its function is to ensure that even if paint drips from the gas valve surface, it will only fall onto the conveyor belt surface and not splatter. The conveyor belt moves the gas valves from the positioning rods to the top of the collection trough, causing them to fall into it.

[0008] Furthermore, the drying structure includes a hot air blower with multiple air outlets distributed along the conveyor belt's conveying direction. Its function is to allow the gas valves on the conveyor belt to be dried by hot air through the hot air intake.

[0009] Furthermore, the hot air blower is located above the top surface of the drying chamber, and the air outlet is located below the top surface of the drying chamber.

[0010] Furthermore, the drying structure also includes infrared radiation lamps. Their function is to radiate heat to the gas valves on the conveyor belt.

[0011] Furthermore, the infrared radiation lamp is installed on the inner wall of the drying oven.

[0012] Furthermore, the infrared radiation lamp is tilted downwards towards the conveyor belt. This is to ensure that the infrared radiation light directly and as much as possible illuminates the gas valve.

[0013] Furthermore, the bottom surface of the drying chamber is equipped with a paint scraper for removing paint from the bottom surface of the conveyor belt. Its function is to remove excess paint from the conveyor belt surface, preventing excessive paint from interfering with the placement of the gas valve.

[0014] Furthermore, the paint scraper is staggered with the positioning rod in the width direction of the conveyor belt. This is to prevent the paint scraper from obstructing the positioning rod.

[0015] Furthermore, the top of the paint scraper is semi-circular.

[0016] Furthermore, the positioning rod is cone-shaped. Its function is to facilitate the insertion of the gas valve.

[0017] The beneficial effects of this utility model are:

[0018] 1. By setting up the positioning rod and the conveyor belt, even if there is paint dripping down the surface of the gas valve, it will only fall onto the surface of the conveyor belt. When the conveyor belt moves the gas valve located on the positioning rod above the collection trough, the gas valve will fall into the collection trough. Attached Figure Description

[0024] Example 1

[0025] A drying device for gas valves after painting includes a drying chamber 1 with an inlet 2 and an outlet 3. A conveyor belt 4 runs through both ends of the drying chamber 1. Positioning rods 5 are provided on the surface of the conveyor belt 4 for inserting into the gas valves. The conveyor belt 4 transports the gas valves placed on the positioning rods 5 from the inlet 2 to the outlet 3. A drying structure is located above the conveyor belt 4, and a collection trough 6 is located below the section of the conveyor belt 4 outside the outlet 3 of the drying chamber 1. Its function is to ensure that even if there are droplets of paint dripping from the gas valve, they will only fall onto the surface of the conveyor belt 4 and not splatter everywhere. The conveyor belt 4 moves the gas valves located on the positioning rods 5 above the collection trough 6, causing the gas valves to fall into the collection trough 6.

[0026] Specifically, such as Figure 1 As shown, the drying structure includes a hot air blower 7, which is connected to multiple air outlets 8, distributed along the conveyor belt 4. Its function is to allow the gas valves on the conveyor belt 4 to be dried by hot air through the placement of the hot air blower 7.

[0027] Specifically, such as Figure 1 As shown, the hot air blower 7 is located above the top surface of the drying chamber 1, and the air outlet 8 is located below the top surface of the drying chamber 1.

[0028] Specifically, such as Figure 1As shown, the drying structure also includes an infrared radiation lamp 9. Its function is to radiate heat to the gas valves on the conveyor belt 4.

[0029] Specifically, such as Figure 1 As shown, the infrared radiation lamp 9 is installed on the inner wall of the drying oven 1.

[0030] Specifically, such as Figure 1 As shown, the infrared radiation lamp 9 is tilted downwards towards the conveyor belt 4. Its function is to ensure that the infrared radiation light directly and as much as possible shines onto the gas valve through the orientation of the infrared radiation lamp 9.

[0031] Specifically, such as Figure 1 As shown, the bottom surface of the drying chamber 1 is provided with a paint scraper 10 for scraping off the paint on the bottom surface of the conveyor belt 4. Its function is to remove the paint from the surface of the conveyor belt 4 by scraping off the paint, so as to avoid excessive paint on the surface of the conveyor belt 4 from affecting the placement of the gas valve.

[0032] Specifically, such as Figure 1 As shown, the paint scraper 10 is staggered with the positioning rod 5 in the width direction of the conveyor belt 4. Its function is to prevent the paint scraper 10 from blocking the positioning rod 5.

[0033] Specifically, such as Figure 1 As shown, the top of the paint scraper 10 is semi-circular.

[0034] Specifically, such as Figure 1 As shown, the positioning rod 5 is cone-shaped. Its function is to facilitate the insertion of the gas valve.

[0035] The working principle of this embodiment is explained as follows: First, the gas valve is placed on the positioning rod 5, and then the transmission belt is started to send the gas valve into the drying box 1 through the inlet 2 of the drying box 1. It is dried by hot air and infrared radiation. Then the gas valve is output to the collection trough 6 directly above the outlet 3 of the drying box 1. When the conveyor belt 4 drives the gas valve to flip, the gas valve falls from the positioning rod 5 into the collection trough 6.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
