In other words, the integrated equipment is composed of two parts, i.e., the vacuum pumping device 400 and the reactor 300, which are connected by a metal pipeline, the buffer tank 420 enables the vacuum mechanism to pump vacuum more stably on the reactor 300, and is favorable for maintaining the pressure of the evacuated cavity, and the filter structure 421 can be a filter screen, which can prevent the activated carbon dust from entering the vacuum pumping device 400.
Further, the vacuum unit 410 comprises a pressure sensor (not shown in the figure), and the pressure sensor is used for sending a pressure maintaining signal when detecting that the pressure of the air inlet of the vacuum unit 410 reaches a preset value. In the process of modified production of the activated carbon, after the activated carbon is placed in the reactor 300 and before the activated carbon is supplied with a formula solution, the containing cavity of the reactor shell 301 needs to be vacuumized and pressure-maintained for a preset time, so that automatic control of vacuumizing can be realized by the arrangement of the pressure sensor, when the pressure in the containing cavity reaches the vacuum degree of a preset value, the pressure sensor sends a pressure-maintaining signal, the vacuum unit 410 monitors the vacuum degree in the containing cavity in real time and keeps the vacuum degree in a preset range, and therefore real-time stable pressure maintaining is realized.

Specifically, the reactor 300 is connected to the base 302 by a first rotating shaft 342 capable of bearing weight and suspending the reactor shell 301 so that the reactor shell 301 rotates. Thus, the evacuated tube passes through a first rotary connection 340, such as a first shaft 342, to evacuate the receiving cavity. The rotation of the first rotating shaft 342 and the reactor shell 301 does not drive the vacuum-pumping pipeline to rotate together, so that the vacuum pumping and the rotation of the reactor shell 301 can be considered and do not interfere with each other.
Further, a first adapter 350 is further included, the first adapter 350 is connected to the first rotating shaft 342 at an end of the first rotating shaft 342 facing away from the reactor shell 301, the first rotating shaft 342 is fixed to the base 302 and can rotate relative to the first adapter 350, and the vacuum pipe passes through an inner hole of the first adapter 350 and is fixed to the first adapter 350.

In some embodiments, the outer wall of the first rotating shaft 342 is provided with a first connecting flange 344 rotatably engaged with the first rotating shaft 342, the outer wall of the first rotating joint 350 is provided with a second connecting flange 343, the first connecting flange 344 and the second connecting flange 343 are connected by a fastener, the first rotating shaft 342 is provided with a positioning groove, the first rotating joint 350 is inserted into the positioning groove, and the first rotating shaft 342 is rotatable relative to the first rotating joint 350.
Specifically, the first connecting flange 344 is fitted in an annular groove formed in the outer wall of the first rotating shaft 342 so as to be axially positioned, while allowing the first rotating shaft 342 to rotate in an inner hole of the first connecting flange 344, the first connecting flange 344 is bolted to a second connecting flange 343 welded to the outer wall of the first rotating joint 350, and a seal ring may be provided between the end surface of the first rotating joint 350 and the end surface of the first rotating shaft 342.
Therefore, the first rotating shaft 342 and the first rotating joint 350 are axially positioned without restricting the rotation of the reactor shell 301, and the structure is compact and the arrangement is reasonable.
As shown in fig. 1, the vacuum-pumping pipe includes a first pipe 431, a second pipe 432 and a four-way joint 433 connecting the first pipe 431 and the second pipe 432, the first pipe 431 is disposed in the first rotating shaft 342 and the first rotating joint 350, one end of the second pipe 432 is connected to the four-way joint 433, the other end of the second pipe 432 is connected to the vacuum-pumping device 400, and two interfaces of the four-way joint 433 are respectively provided with a pressure gauge 434 and a temperature gauge 435. Through setting up manometer 434 and thermometer 435 directly on the evacuation pipeline to the temperature of holding the intracavity is surveyed indirectly through pressure and the temperature detection to the evacuation pipeline, has avoided additionally to set up the pipeline, has improved the life of manometer 434 and thermometer 435 moreover.
Of course, the temperature meter 435 and the pressure meter 434 may be disposed on the evacuation pipeline, or may be separately led out from the accommodating cavity to monitor the temperature and the vacuum degree in the accommodating cavity.
In addition, a control valve is arranged on the vacuum-pumping pipeline between the four-way joint 433 and the vacuum-pumping device 400. Therefore, the opening and closing state of the control valve is reasonably changed according to whether vacuum pumping is needed or not and pressure maintaining is needed or not, so that the vacuum pumping device 400 can pump vacuum.
The reactor housing 301 is described below with reference to fig. 3-5, the reactor housing 301 comprising: an outer housing 310, an inner housing 320.
As shown in fig. 3, the inner housing 320 is connected to the outer housing 310 at the inner side of the outer housing 310, a containing cavity a for containing activated carbon is defined in the inner housing 320, the inner housing 320 and the outer housing 310 together define a circulating cavity b for containing a heat exchange medium, and the circulating cavity b includes a liquid inlet cavity 321 disposed adjacent to the inner housing 320 and a liquid return cavity 311 communicated with the liquid inlet cavity 321 at the outer side of the liquid inlet cavity 321.
That is to say, hold and to hold the active carbon that can hold in the chamber a, the active carbon holds chamber a inner shell and is easily impregnated by the prescription and then modified processing to make the active carbon can adhere to the impregnating solution, and then have better adsorption performance. The heat exchange medium (such as oil) flows from the external drying device to the liquid inlet cavity 321, fully exchanges heat with the inner shell 320, flows to the liquid return cavity 311, and flows back to the external drying device from the liquid return cavity 311, so that the heat exchange medium circularly flows to realize continuous heat exchange. Certainly, when the heat exchange medium in the circulation cavity b is the liquid with higher temperature, the heat exchange medium can be used for heating the accommodating cavity a, and conversely, when the heat exchange medium in the circulation cavity b is the liquid with lower temperature, the heat exchange medium can be used for cooling the accommodating cavity a.
It should be noted that the flow-through chamber b may be partially defined by the outer housing and partially defined by the inner housing 320, or the flow-through chamber b may be located between the inner housing 320 and the outer housing 310. The liquid inlet cavity 321 and the liquid return cavity 311 may be distributed in sequence in a radial direction away from the receiving cavity a.
Therefore, the circulation cavity b is directly formed in the outer shell 310 and/or the inner shell 320, and the liquid inlet cavity 321 is arranged close to the inner shell 320, so that the heat exchange medium can be directly contacted with the inner shell 320, the problem of large energy loss of the coil type heat exchanger is avoided, and the full utilization of heat or cold is realized.
In some embodiments, the shape of the liquid inlet chamber 321 corresponds to the shape of the inner casing 320, and the liquid inlet chamber 321 is disposed around the inner casing 320. Specifically, the reactor shell 301 has a double-cone shape, and the liquid inlet cavity 321 includes a cylindrical cavity and two truncated cone cavities respectively connected to two ends of the cylindrical cavity.

In some embodiments, the liquid return chamber 311 extends linearly, and the liquid return chamber 311 is opposite to a portion of the liquid inlet chamber 321 on the outer side of the liquid inlet chamber 321. Therefore, the space occupied by the liquid return cavity 311 is small, the space is saved, the heat exchange between the liquid return cavity and the liquid inlet cavity 321 is reduced, and heat or cold can be intensively used for heating or cooling the accommodating cavity a.
As shown in fig. 4, the inner shell 320 and the outer shell 310 are both a solid of revolution disposed around the central axis e, the two ends of the inner shell 320 disposed opposite to each other in the direction of the central axis e are respectively formed with a feed port 322 and a discharge port 323, the middle portion of the reactor shell 301 along the direction of the central axis e is formed as a rotation center f, the rotation center f is perpendicular to the central axis e, and the feed liquid chamber 321 is configured to feed liquid from a position close to the rotation center f and discharge liquid from a position close to the feed port 322 and the discharge port 323 to the return liquid chamber 311.
From this, under the more abundant prerequisite of guaranteeing that reactor shell 301 is rotatory so that hold the active carbon in the chamber a and be impregnated, make feed liquor chamber 321 can be closer to rotation center f to can make the feed liquor structure not influenced by reactor 300 rotation, compromise circulation and the rotation of reactor shell 301 of the heat transfer medium of circulation chamber b.
