[0003] The prior art discloses a quantitative conveying device for carbon nanotube catalysts (CN202222768716.9), comprising: a quantitative mechanism and a conveying mechanism. The quantitative mechanism includes a hopper, which has interconnected inner chambers. The bottom opening of the inner chambers is movably connected to a hopper door via an opening and closing assembly. Weighing components are symmetrically arranged on both sides of the outer wall of the hopper. Each weighing component includes a support rod with an open top groove. A pressure sensor is slidably connected within the groove. A connecting rod is detachably connected above the pressure sensor.

[0004] The catalyst is mostly ultrafine powder, which is prone to agglomeration and blockage on the inner wall of the inner chamber. The vibrating motor alone cannot completely break up the agglomerated powder. After descending from the hopper gate and being pushed into the outer reaction chamber by the pusher plate, the reaction effect is poor and the efficiency is low.

[0005] In view of this, this utility model is proposed. Utility Model Content

Inside the inner chamber are two clamping plates that can close together, forming a cone-shaped structure that fits the inner chamber.

[0007] In a preferred embodiment of the present invention, the clamping and scraping wall structure further includes a central rod and rotating columns. One side of one clamping plate is fixedly connected to the middle of the central rod, and one side of the other clamping plate is fixedly connected to the two rotating columns.

[0013] Compared with the prior art, the present invention has the following advantages: 1.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0019] A quantitative feeding device for carbon nanotube catalysts, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a catalytic scraping structure is installed inside the hopper 2. The hopper 2 contains an inner chamber 8 for storing catalyst. Inside the inner chamber 8 are two clamping plates 9 that can close together. The overall shape of the two clamping plates 9 is conical and fits the inner chamber 8. The catalytic scraping structure also includes a central rod 6 and rotating columns 12. One side of one clamping plate 9 is fixedly connected to the middle of the central rod 6, and one side of the other clamping plate 9 is fixedly connected to the two rotating columns 12. The central rod 6 passes through the two rotating columns 12 and is rotatably connected to them. A transmission rod 7 is fixedly mounted on one side of the central rod 6. The rotating column 12 passes through the top surface of the hopper 2 and is rotatably connected to the hopper 2. A transmission rod 7 is fixedly installed at the end of the upper rotating column 12. The squeezing and scraping structure also includes a sliding groove 5 and a slider 11. The top surface of the hopper 2 is fixedly connected to two sliding grooves 5. The two sides of the slider 11 are slidably connected to the middle of one sliding groove 5. The squeezing and scraping structure also includes a moving groove 13. One end of each of the two transmission rods 7 is slidably connected to a moving groove 13. An electric telescopic rod 4 is fixedly installed on the top surface of the hopper 2. The output shaft of the electric telescopic rod 4 is fixedly connected to one side of the slider 11. The top surface of the inner chamber 8 is fixedly connected to the hopper 2.

[0020] Once the catalyst reaches the preset value in the inner chamber 8, the power to the electric telescopic rod 4 is turned on. The electric telescopic rod 4 drives the slider 11 to move, and the slider 11 drives the two transmission rods 7 to slide in the moving groove 13. While sliding, the central rod 6 and the rotating column 12 rotate relative to each other, and the two clamping plates 9 come together to clamp and break up the clumps of catalyst. The small pieces of catalyst can be quickly broken up with the help of the vibration motor. The fine powder reacts faster and has a better reaction effect in the subsequent catalytic process. When the inclined surfaces of the two clamping plates 9 rotate along the wall of the inner chamber 8, they can scrape off the powder attached to the wall of the inner chamber 8, effectively avoiding the powder from sticking to the wall and causing dosage loss.

[0021] A quantitative feeding device for carbon nanotube catalysts, such as Figure 1 As shown, a conveying cylinder 1 is fixed above the ground. A hopper 2 is provided above the conveying cylinder 1. A feed inlet 3 is opened on the top surface of the hopper 2 away from the center. The feed inlet 3 communicates with the inner chamber 8. A hopper gate 10 is provided on the bottom surface of the inner chamber 8. A quantitative feeding device for carbon nanotube catalysts also includes a support rod, a chute, a pressure sensor, a connecting rod, a support plate, a push plate, a first telescopic cylinder, a first hinge seat, a second hinge seat, an adjusting groove, an adjusting block, a locking block, bolts, bolt grooves, a compression spring, corrugated wires, a vibration motor, a second telescopic cylinder, and a support rod. It is worth noting that the above structure, conveying cylinder 1, hopper 2, feed inlet 3, and hopper gate 10 are all prior art and have been disclosed in a quantitative feeding device for carbon nanotube catalysts (CN202222768716.9). The specific implementation method will not be described in detail here.

[0022] By adjusting the position of the pressure sensor in the chute, the preset value of the required catalyst raw material weight can be adjusted. The preset value is used to remove the weight of the scraping structure beforehand. The catalyst is poured in from the feed inlet 3, thereby realizing the quantitative measure of the catalyst raw material and improving the quantitative accuracy. Furthermore, the opening and closing of the hopper gate 10 is controlled by the opening and closing component, so that the catalyst raw material directly enters the conveying cylinder 1 and is pushed into the reaction chamber.

[0023] The working principle of this utility model is as follows: By adjusting the position of the pressure sensor in the chute, the preset value of the required catalyst raw material weight can be adjusted. The preset value excludes the weight of the scraping and dispersing structure. The catalyst is poured in from the feed inlet 3, thereby achieving quantitative measures for the catalyst raw material and improving the accuracy of quantitative measurement. When the catalyst reaches the preset value in the inner chamber 8, the power of the electric telescopic rod 4 is turned on. The electric telescopic rod 4 drives the slider 11 to move. The slider 11 drives the two transmission rods 7 to slide in the moving groove 13. While sliding, the central rod 6 and the rotating column 12 rotate relative to each other. The two clamping plates 9 come together to clamp and disperse the clumps of catalyst. Small pieces of catalyst can be quickly dispersed with the help of the vibration motor. The fine powder reacts faster and has a better reaction effect in the subsequent catalytic process. When the inclined surfaces of the two clamping plates 9 rotate along the wall of the inner chamber 8, they can scrape off the powder attached to the wall of the inner chamber 8, effectively avoiding the powder adhering to the wall and causing dosage loss. The opening and closing of the hopper door 10 is controlled by the opening and closing component, so that the catalyst raw material directly enters the conveying cylinder 1 and is pushed into the reaction chamber.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
