Description

Technical Field

[0001] The utility model relates to the technical field of catalyst feeding, and specifically to a catalyst feeding device. Background Art

[0002] The catalyst feeding device is a device used to automatically or semi-automatically add catalyst to the reactor. Its main function is to ensure that the catalyst can be evenly dispersed in the reactants, thereby improving the reaction efficiency and stability.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 The utility model provides a technical solution of a catalyst feeding device: a catalyst feeding device, comprising a reaction tank 1, a feeding pipe 11 fixedly connected to the top of the reaction tank 1, and a discharge pipe 12 fixedly connected to the bottom of the reaction tank 1, a bracket 2 is fixedly connected to the top of the reaction tank 1, and a stirring blade 3 is arranged inside the reaction tank 1;

[0023] refer to Figure 3-Figure 4 As shown, in order to avoid excessive catalyst or accumulation of catalyst to react with raw materials, the following optimal addition amount and addition method are specially made to ensure that the catalyst is evenly dispersed, does not agglomerate, and can fully contact with the reactant raw materials, thereby improving the reaction efficiency and stability of the raw materials. The inner cavity of the bracket 2 is provided with a driving mechanism 4 that rotates the stirring blade 3 to stir the raw materials in the reaction tank 1, and a dosing mechanism 5 that synchronously drives the driving mechanism 4 to put a small amount of catalyst into the reaction tank 1 multiple times to accelerate the reaction of the raw materials;

[0024] Specifically, the driving mechanism 4 includes a cylinder 41, which is fixed to the inner wall of the bracket 2, and the telescopic end of the cylinder 41 is fixedly connected to a fixing plate 42, and the fixing plate 42 is arranged in an n-shaped shape, and a threaded rod 44 is arranged in the inner cavity of the fixing plate 42, and the outer wall of the threaded rod 44 does not contact the inner side wall of the fixing plate 42, and the bottom end of the fixing plate 42 is fixedly connected to a driving block 43, and the inner cavity of the bracket 2 is symmetrically vertically provided with two limit grooves, and two limit blocks are symmetrically fixedly connected to the two sides of the driving block 43, and the two limit blocks are arranged along the inner cavity of the bracket 2. The two limit grooves slide up and down in the height direction, and the internal thread of the driving block 43 is connected to the threaded rod 44. The threaded rod 44 is a thread with a specific angle, and the spacing between the threads is large. The bottom end of the threaded rod 44 is fixedly connected to the rotating rod 45, and the stirring blade 3 is fixed to the outer wall of the rotating rod 45. The cylinder 41 is started to drive the fixed plate 42 to move downward at the telescopic end. The fixed plate 42 moves downward to push the driving block 43 to move downward on the outer wall of the threaded rod 44, causing the threaded rod 44 to rotate, and then the rotating rod 45 drives the stirring blade 3 to rotate to mix the raw materials;

[0025] More specifically, the dosing mechanism 5 includes an airbag 53, the bottom of which is fixed on the top of the reaction tank 1, a connecting plate 51 is fixedly connected to the side of the driving block 43 away from the feed pipe 11, and a pressure plate 52 is fixedly connected to the end of the connecting plate 51 away from the driving block 43, the top of the airbag 53 is fixed to the bottom of the pressure plate 52, the side of the airbag 53 is fixedly connected to a one-way feed pipe 54, and the bottom of the airbag 53 is fixedly connected to a one-way dosing pipe 55. The driving block 43 moves downward to cause the connecting plate 51 to drive the pressure plate 52 to move downward to squeeze the airbag 53, so that the catalyst entering the airbag 53 through the one-way feed pipe 54 is sprayed into the reaction tank 1 through the one-way dosing pipe 55, and the stirring blade 3 rotates to ensure that the catalyst can fully contact with the raw materials, thereby ensuring that the catalyst is evenly dispersed and does not agglomerate.

When the fixed plate 42 moves down, the driving block 43 can be pushed to move down on the outer wall thread of the threaded rod 44, so that the stirring blade 3 rotates forward to mix the raw materials. At the same time, the connecting plate 51 drives the pressing plate 52 to move down and squeeze the air bag 53, so that the catalyst in the air bag 53 is sprayed into the reaction tank 1 through the one-way feed pipe 55 to fully contact with the raw materials. When the fixed plate 42 moves up, the stirring blade 3 is reversed to mix the raw materials. At the same time, the air bag 53 is reset and the catalyst in the catalyst storage tank is drawn into the air bag 53 again through the one-way feed pipe 54, so as to achieve the effect of small amount and large amount of catalyst. The reaction efficiency and stability of the raw materials can be improved by repeating the above process.
