Description

Technical Field

[0001] The utility model relates to a waste catalyst metering tank, in particular to the technical field of metering tanks. Background Art

[0002] Waste catalyst refers to the catalyst used in industrial fields such as petroleum plants and refineries. Due to chemical changes and the generation of pollutants during the reaction process, the catalyst performance is reduced and then discarded. The waste catalyst metering tank is a container for storing and measuring waste catalysts.

[0003] The patent with the patent authorization announcement number CN218424628U discloses a metering tank, which uses a driving member to drive a hammer to repeatedly hit the outer wall of the tank body to vibrate, so that the material on the inner wall of the tank body falls off and is discharged. However, the metering tank provided by the patent still has some shortcomings in actual use. The waste catalyst is not only solid, but also partially liquid. When the tank body is hammered, the solid waste catalyst and partially liquid waste catalyst will be discharged, but some residual liquid waste catalyst will still adhere to the inner wall of the metering tank and cannot be discharged. The staff needs to clean it separately, which is more cumbersome.

[0004] Therefore, it is necessary to provide a metering tank that can automatically clean the waste catalyst residue on the inner wall of the metering tank. Utility Model Content

[0021] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position.

[0022] Example 1: A waste catalyst metering tank, see Figure 1-Figure 4 As shown, it includes a mounting plate 1, a metering tank 2 and a discharge pipe 9. The metering tank 2 is mounted on the mounting plate 1, and the discharge pipe 9 is connected to the metering tank 2. It also includes a drive motor 5, a fixed rod 6, a stirring rod 7 and a scraper 8. The drive motor 5 is installed on the metering tank 2 by bolt connection, and the output shaft of the drive motor 5 is installed with the fixed rod 6 through a coupling. The stirring rod 7 is symmetrically installed on the fixed rod 6, and the scraper 8 is installed on the fixed rod 6. The scraper 8 contacts the inner wall of the metering tank 2.

[0023] See also Figure 1 , Figure 3 and Figure 4 As shown, it also includes an observation window 3 and a protective shell 4. The observation window 3 is embedded in the metering tank 2, and the protective shell 4 for protecting the driving motor 5 is fixedly connected to the metering tank 2.

[0024] When the waste catalyst in the metering tank 2 is discharged and the discharge speed needs to be accelerated, the drive motor 5 is started so that the output shaft of the drive motor 5 drives the fixed rod 6 and the stirring rod 7 to rotate, thereby accelerating the discharge of the waste catalyst; after the waste catalyst in the metering tank 2 is discharged, some waste catalyst will remain on the inner wall of the metering tank 2. When the waste catalyst on the inner wall of the metering tank 2 needs to be removed, the fixed rod 6 is driven by the output shaft of the drive motor 5 to drive the scraper 8 to rotate, thereby automatically scraping off the waste catalyst on the inner wall of the metering tank 2 for easy cleaning.

[0025] Example 2: Based on Example 1, refer to Figure 1 and Figure 3As shown, it also includes a fixed block 11, a discharge hopper 12, a protective shell 13, a discharge pipe 14, a servo motor 15, a connecting rod 16 and a spiral conveying piece 17. The metering tank 2 is connected to the discharge pipe 14, and the discharge pipe 14 is fixedly connected to the fixed block 11. The fixed block 11 is flush with the bottom surface of the mounting plate 1, and the discharge hopper 12 is fixedly connected to the side of the discharge pipe 14 close to the fixed block 11. The servo motor 15 is installed on the side of the discharge pipe 14 away from the fixed block 11. The output shaft of the servo motor 15 is installed with a connecting rod 16 through a coupling, and the connecting rod 16 is fixedly connected to the spiral conveying piece 17. The fixed block 11 is fixedly connected to a protective shell 13 for protecting the servo motor 15 and the discharge pipe 14.

[0026] When the waste catalyst is injected into the metering tank 2, it is necessary to pour the waste catalyst into the discharge hopper 12, and by starting the servo motor 15, the output shaft of the servo motor 15 drives the connecting rod 16 and the spiral conveying piece 17 to rotate, so that the spiral conveying piece 17 conveys the waste catalyst from the discharge pipe 14 to the metering tank 2, so as to facilitate storage by the staff and speed up storage efficiency. The protective shell 13 can protect the servo motor 15.

[0027] See also Figure 4 As shown, it also includes a weighing plate 19 and a weight display 20. The weighing plate 19 is installed on the mounting plate 1, and the weighing plate 19 is connected to the discharge pipe 9 below. The weight display 20 is installed on the weighing plate 19 by bolt connection.

[0028] See also Figure 3 and Figure 4 As shown, a protective plate 18 is also included. The protective plate 18 for protecting the weighing plate 19 is installed on the mounting plate 1 by welding.

[0029] When the waste catalyst in the metering tank 2 is to be discharged, the container needs to be placed on the weighing plate 19, and then the valve on the discharge pipe 9 is opened to allow the waste catalyst to fall into the container and pass through the weighing plate 19 to be weighed. The weighing value is displayed on the weight display 20 to facilitate the staff to record the weight of the waste catalyst. The protective plate 18 covers both sides of the weighing plate 19 to prevent the weighing plate 19 from being damaged.

[0031] See also Figure 1 and Figure 3 As shown, a metering device 10 is also included, and the metering tank 2 is equipped with the metering device 10 .

[0032] The meter 10 is used to measure the amount of waste catalyst in the metering tank 2 in milliliters, which is convenient for the staff to record. The dustproof cover 21 can prevent dust from falling on the weight display 20, thereby affecting the numerical display.

[0033] It should be understood that the above description is only for exemplary purposes and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
