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

[0021] like Figures 1 to 8As shown, an embodiment of the present invention provides a device for preparing a new type of neutralizing agent coal-based activated carbon, including a processing tube 1, a feeding component 2 is fixedly sleeved on the top of the processing tube 1, a rotating mechanism 3 is above the feeding component 2, a high-temperature steam input mechanism 4 is fixedly sleeved on the outer side of the processing tube 1, and an auxiliary material feeding mechanism 8 is fixedly connected to the side of the feeding component 2. A rotating heating part 5 is rotatably installed inside the processing tube 1, a combined lower stirring component 6 is fixedly connected to the top of the rotating heating part 5, a combined upper stirring component 7 is fixedly connected to the top of the combined lower stirring component 6, and the combined upper stirring component 7 is rotatably sleeved in the feeding component 2. A power mechanism 11 and a negative pressure component 10 are respectively provided at the bottom of the processing tube 1. The negative pressure component 10 controls the combined upper stirring component 7 to open the feeding component 2 through the rotating heating part 5 and the combined lower stirring component 6. A heating pipe 12 is fixedly provided inside the rotating heating part 5, and a guiding mechanism 9 is fixedly sleeved inside the processing tube 1.

[0022] Embodiment 1: When in use, the crushed coal to be processed is put into the loading barrel 21 of the loading assembly 2, and the rotating mechanism 3 is started to drive the spiral blade 23 to rotate. The material is transported downward along the inside of the loading barrel 21 and falls on the top of the filter plate 13 and the sealing disk 71. The top of the auxiliary material feeding mechanism 8 is opened, and the neutralizer block is put in and also falls on the top of the filter plate 13. The power mechanism 11 is started and the rotating heating part 5 is driven to rotate, driving the combined lower stirring assembly 6 to rotate, and driving the combined upper stirring assembly 7 to rotate, so that the stirring plate 2 76 rotates to stir the coal and the neutralizer to mix. At the same time, the heating tube 12 in the rotating heating part 5 in the processing barrel 1 is started, the temperature inside the processing barrel 1 increases, and the coal and the neutralizer react at high temperature. Subsequently, the negative pressure component 10 is started, and the negative pressure component 10 sucks the air inside the distribution cover 103 through the vacuum pump 101 and the support tube 102, and the connecting cavity 55 in the rotating heating part 5 and When the distribution port 104 is aligned and connected, the air in the middle hole 54 is sucked, and the air in the sleeve 61 is sucked. Under the action of negative pressure, the piston plate 73 is pulled downward to move, and the spring 63 is compressed, so that the push rod 72 works the sealing plate 71 to open the bottom of the loading barrel 21 downward. The reacted coal that has lost its support falls along the filter holes of the filter plate 13 and falls onto the mounting plate 51. When the connecting chamber 55 rotates and is staggered with the distribution port 104, and is aligned with the bypass hole on the distribution cover 103, the air pressure in the combined lower stirring assembly 6 is restored, the spring 63 elastically serves, and the sealing plate 71 moves up to perform the pre-reaction of the next group of automatically filled materials, and the rotating stirring plate 62 rotates to stir the materials that fall on the mounting plate 51, and at the same time, the external high-temperature water vapor is introduced into the high-temperature water vapor input mechanism 4, and is sprayed onto the mounting plate 51 through the guiding mechanism 9, so as to realize the formation of coal pores under the action of high-temperature water vapor, and complete further activation treatment.

[0023] Firstly, by utilizing the connection and coordination between the feeding assembly 2 and the auxiliary material feeding mechanism 8, and combining the upper stirring assembly 7 controlled by the up and down movement, an independent pretreatment space is formed. In the actual activation treatment process, the high temperature effect in the treatment cylinder 1 during the high-temperature steam activation treatment process is utilized. While realizing the high-temperature steam treatment, the coal is pre-chemically activated. This avoids performing activation treatments in different equipment separately, reduces the intermediate transfer steps, realizes quick and continuous double activation treatments, and improves the actual activation efficiency.

[0024] In addition, by utilizing the connection and coordination between the feeding assembly 2 and the auxiliary material feeding mechanism 8, and combining the upper stirring assembly 7 with the upper and lower movement control, an independent pretreatment space is formed, and in conjunction with the filter plate 13 and the stirring plate 2 76 in the pretreatment space, synchronous rotation and stirring treatment is achieved in the actual pretreatment process.
