For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.

[0029] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a chemical catalyst addition device, comprising:

[0031] Support frame 1, on which a chemical catalyst adding mechanism is provided. It should be noted that the chemical catalyst adding mechanism facilitates the quantitative addition of chemical catalysts, thereby improving production efficiency.

[0032] The chemical catalyst addition mechanism includes a weighing platform 2, a frustum 3, a chemical catalyst storage tube 4, a ring 6, a slide bar 8, a crossbar 10, a sealing plate 11, a hydraulic cylinder 14, and a positioning component 15;

[0033] The support frame 1 is fixedly connected to the weighing platform 2. The truncated cone 3 is fixedly installed on the top of the weighing platform 2. The chemical catalyst storage tube 4 is fixedly installed on the truncated cone 3. The slide rod 8 is slidably installed on the ring 6. The crossbar 10 is fixedly connected to the slide rod 8. The sealing plate 11 is fixedly installed on the crossbar 10. The hydraulic rod of the hydraulic cylinder 14 is fixedly connected to the positioning component 15. The positioning component 15 is engaged with the crossbar 10.

[0034] The above-mentioned chemical catalyst adding mechanism activates the hydraulic cylinder 14, causing the positioning element 15 to move out of the positioning hole 16 on the crossbar 10. This facilitates the weighing platform 2 to accurately weigh the chemical catalyst added to the chemical catalyst storage tube 4. After the specified addition amount is reached, the hydraulic cylinder 14 is activated, causing the positioning element 15 to engage with the positioning hole 16 on the crossbar 10.

[0035] Specifically, the chemical catalyst addition mechanism also includes a connecting rod 5, an arc-shaped hole 7, a power motor 12, and a drive disc 13. The connecting rod 5 is fixedly installed between the frustum 3 and the ring 6. The arc-shaped hole 7 is opened at the top of the ring 6. The slide rod 8 is slidably installed inside the ring 6. Two sleeves 9 are fixedly sleeved on the outside of the slide rod 8. The sleeves 9 abut against the ring 6. The output end of the power motor 12 is fixedly connected to the drive disc 13. The hydraulic cylinder 14 is fixedly installed on the drive disc 13.

[0036] It should be noted that the support frame 1 and the power motor 12 are both fixedly installed on the top of the mixing box. The top of the mixing box is provided with two catalyst addition holes, which are located directly below the chemical catalyst storage pipe 4. This makes it convenient to add the weighed chemical catalyst into the catalyst addition holes. In addition, the mixing box is equipped with a stirrer for stirring. By adding the chemical catalyst from both sides at the same time and stirring during the addition process, the processing efficiency can be improved.

[0037] Through the aforementioned chemical catalyst addition mechanism, the power motor 12 is started, which drives the drive disc 13 to rotate. The drive disc 13 drives the hydraulic cylinder 14 to rotate, and the hydraulic cylinder 14 drives the crossbar 10 to rotate through the positioning component 15. The crossbar 10 drives the sealing plate 11 and the sliding rod 8 to rotate, so that the sealing plate 11 is separated from the chemical catalyst storage tube 4. At this time, the chemical catalyst weighed in the chemical catalyst storage tube 4 falls into the mixing box below for processing. Then, the sealing plate 11 is driven back to its original position.

[0038] Specifically, a chemical catalyst addition pipe 17 is provided above the chemical catalyst storage pipe 4, and a solenoid valve 18 is installed on the chemical catalyst addition pipe 17. It should be noted that an external controller is set up, and both the solenoid valve 18 and the weighing platform 2 are electrically connected to the controller. When the weighing result of the weighing platform 2 reaches the set value, the controller closes the solenoid valve 18.

[0039] Specifically, the crossbar 10 has a positioning hole 16, and the positioning part 15 is engaged with the positioning hole 16. It should be noted that this facilitates the docking of the positioning part 15 with the crossbar 10.

[0040] Specifically, the ring 6 is located on the outside of the weighing platform 2, and a damping washer is embedded in the sleeve 9. The damping washer abuts against the ring 6. It should be noted that there is a large friction between the damping washer and the ring 6. In this way, after the positioning part 15 moves out of the positioning hole 16, it can ensure that the slide bar 8, the sleeve 9 and the cross bar 10 are stably in a certain position, which makes it convenient for the positioning part 15 to be inserted into the positioning hole 16 later.

[0041] Specifically, two mounting holes are provided on the truncated cone 3, and the chemical catalyst storage tube 4 is fixedly installed in the mounting holes. It should be noted that this is to facilitate the installation of the chemical catalyst storage tube 4.

[0042] Specifically, the sealing plate 11 abuts against the bottom of the chemical catalyst storage tube 4. It should be noted that this can seal the bottom of the chemical catalyst storage tube 4.

[0043] Working principle:

[0044] S1: Start the hydraulic cylinder 14 to move the positioning part 15 out of the positioning hole 16 on the crossbar 10. The damping washer and the ring 6 have a large friction force. After the positioning part 15 moves out of the positioning hole 16, the slide bar 8, the sleeve 9 and the crossbar 10 can be kept in a stable position, which makes it easy for the positioning part 15 to be inserted into the positioning hole 16 later. The solenoid valve 18 and the weighing platform 2 are electrically connected to the external controller. When the weighing result of the weighing platform 2 reaches the set value, the controller closes the solenoid valve 18. This makes it easy for the weighing platform 2 to accurately weigh the chemical catalyst added to the chemical catalyst storage tube 4.

[0045] S2: Since the power motor 12 is installed on the mixing box below, the hydraulic cylinder 14 is installed on the drive plate 13, and the positioning part 15 is installed on the hydraulic rod of the hydraulic cylinder 14, in order to ensure the weighing accuracy, the positioning part 15 needs to be moved out of the positioning hole 16, and the hydraulic cylinder 14 needs to be started so that the positioning part 15 can be inserted into the positioning hole 16 on the crossbar 10.

[0046] S3: Start the power motor 12. The power motor 12 drives the drive disc 13 to rotate. The drive disc 13 drives the hydraulic cylinder 14 to rotate. The hydraulic cylinder 14 drives the crossbar 10 to rotate through the positioning component 15. The crossbar 10 drives the sealing plate 11 and the sliding rod 8 to rotate, so that the sealing plate 11 is separated from the chemical catalyst storage tube 4. At this time, the chemical catalyst weighed in the chemical catalyst storage tube 4 falls into the mixing box below for processing. Then, the sealing plate 11 is driven back to its original position.

[0047] The above provides a detailed description of a chemical catalyst addition device provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core idea of ​​this utility model.
