Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a drum reactor. Background Technology

[0002] In chemical production, it is necessary to use corresponding reactors to mix and transport various chemical raw materials. Existing mixing reactions are usually carried out in reaction tanks or reaction pools, which are intermittent reaction operations. This makes it impossible to continuously mix and transport multiple chemical raw materials, resulting in low efficiency in mixing and transporting chemical raw materials.

[0003] A search revealed a Chinese patent application with patent number CN202320530109.0, which discloses a waste acid neutralization reactor. This reactor can continuously mix and transport chemical raw materials, increasing the chemical raw material mixing and reaction processing capacity of the device. Furthermore, the reactants move slowly in a spiral motion within the drum reactor, increasing the safety performance of the device. In addition, the raw materials are in full contact within the device, resulting in a more complete reaction and reducing the consumption quota of raw materials.

[0004] However, since the above technical solution does not have a corresponding mechanism to effectively seal the connection between the two sides of the cylinder and the feed and discharge ends, there is still a problem that when the cylinder rotates slowly, the chemical raw materials inside the cylinder can easily spill out from the gaps between the two ends of the cylinder and the feed and discharge ends. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drum reactor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A drum reactor includes a metal drum, to which a plastic drum is slidably connected. A discharge box and a feed box are inserted into the outer walls of both ends of the plastic drum. The outer walls of the discharge box and the feed box on opposite sides have insertion holes. Both ends of the plastic drum are inserted into the inner walls of these insertion holes. A first sealing ring is fixed to the outer wall of one side of the insertion hole. A second sealing ring is slidably connected to the outer wall of the plastic drum. The outer walls of the first and second sealing rings each have second fixing holes. Multiple elastic sealing gaskets are sandwiched between the second and first sealing rings. The outer walls of the elastic sealing gaskets have a set of first fixing holes, which are fixed to the second sealing ring and the second fixing holes on the outer walls of the first sealing ring by bolts.

[0008] As a further improvement of this utility model: the inner wall of the plastic rotating cylinder is fixed with spiral blades, and the outer wall of the metal rotating cylinder is welded with multiple welding blocks.

[0009] As a further improvement of this utility model: the outer wall of the metal rotating cylinder has multiple fixed through grooves, and the welding block is snapped onto the inner wall of the fixed through groove.

[0010] As a further embodiment of this utility model: multiple rolling rings are fixed on the outer wall of the metal drum, and a first support wheel seat and a second support wheel seat are tumblingly connected to one side of the outer wall of the rolling rings. A support plate is fixed on the bottom outer wall of the first support wheel seat and the second support wheel seat.

[0011] As a further improvement of this utility model, the heights of the first support wheel seat and the second support wheel seat relative to the support plate decrease sequentially.

[0012] As a further embodiment of this utility model: a reduction motor is fixed to the outer wall of the support plate, an external gear ring is fixed to the outer wall of the metal drum, and the output shaft of the reduction motor is connected to the outer wall of the external gear ring through gear meshing.

[0013] As a further improvement of this utility model: a feed pipe is inserted into the outer wall of the feed box, an observation port and a liquid outlet are provided on the outer wall of the discharge box, and a waste discharge port is provided on one side of the outer wall of the discharge box.

[0014] As a further improvement of this utility model, exhaust pipes are respectively inserted into the top outer walls of the discharge box and the feed box.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The operator only needs to insert multiple elastic sealing gaskets one side overlap between the second sealing ring and the first sealing ring. After aligning the first fixing holes on the outer walls of two adjacent overlapping elastic sealing gaskets, the two overlapping elastic sealing gaskets can be clamped and fixed between the first sealing ring and the second sealing ring by bolts. Multiple elastic sealing gaskets are quickly overlapped and clamped and fixed on the outer wall of the connection between the plastic cylinder and the socket. Through multiple elastic sealing gaskets tightly attached to the outer wall of the plastic cylinder, the gap between the plastic cylinder and the socket is effectively sealed without affecting the rotation of the plastic cylinder on the inner wall of the socket.

[0017] 2. The operator can control the rotation speed of the metal drum and the plastic drum as a whole by controlling the speed of the geared motor. This will drive the metal drum and the plastic drum to rotate at a certain speed under the support of the first support wheel seat and the second support wheel seat. The spiral blades inside the plastic drum will stir, mix and transport the chemical raw materials that enter the plastic drum through the feed box, so that the chemical raw materials can be fully mixed and reacted inside the plastic drum.

[0030] Example 1

[0031] Rotary drum reactor, such as Figure 1-7 As shown, the device includes a metal rotating drum 1, a plastic rotating drum 5 slidably connected to the inner wall of the metal rotating drum 1, a discharge box 6 and a feed box 14 inserted into the outer walls of both ends of the plastic rotating drum 5, and insertion holes 20 respectively opened on the outer walls of opposite sides of the discharge box 6 and the feed box 14. The two ends of the plastic rotating drum 5 are respectively inserted into the inner walls of the insertion holes 20. A first sealing ring 21 is fixed to one side of the outer wall of the insertion hole 20. A second sealing ring 24 is slidably connected to the outer wall of the plastic rotating drum 5. The outer walls of the first sealing ring 21 and the second sealing ring 24 are respectively opened with second fixing holes 23. Multiple elastic sealing gaskets 22 are sandwiched between the second sealing ring 24 and the first sealing ring 21. A set of first fixing holes 19 are opened on the outer wall of the elastic sealing gasket 22. The first fixing holes 19 are fixed to the second fixing holes 23 on the outer walls of the second sealing ring 24 and the first sealing ring 21 by bolts.

[0032] The inner wall of the plastic rotating cylinder 5 is fixed with spiral blades 17, and the outer wall of the metal rotating cylinder 1 is welded with multiple welding blocks 4.

[0033] The outer wall of the metal rotating cylinder 1 has multiple fixed through slots 18, and the welding block 4 is snapped onto the inner wall of the fixed through slot 18.

[0034] The staff first inserts the plastic rotating cylinder 5 into the corresponding metal rotating cylinder 1, and then passes the welding block 4 through the corresponding fixing groove 18 on the outer wall of the metal rotating cylinder 1 and welds it to the outer wall of the plastic rotating cylinder 5. Thus, by welding and fixing multiple welding blocks 4 to the outer wall of the plastic rotating cylinder 5, the plastic rotating cylinder 5 is snapped and fixed to the inner wall of the metal rotating cylinder 1.

[0035] The outer wall of the metal drum 1 is fixed with a plurality of rolling rings 3. A first support wheel seat 9 and a second support wheel seat 13 are tactilely connected to one side of the outer wall of the rolling rings 3. A support plate 2 is fixed to the bottom outer wall of the first support wheel seat 9 and the second support wheel seat 13.

[0036] The heights of the first support wheel seat 9 and the second support wheel seat 13 relative to the support plate 2 decrease sequentially.

[0037] A reduction motor 12 is fixed to the outer wall of the support plate 2, and an external gear ring 11 is fixed to the outer wall of the metal drum 1. The output shaft of the reduction motor 12 is connected to the outer wall of the external gear ring 11 through gear meshing.

[0038] The operator can control the rotation speed of the metal drum 1 and the plastic drum 5 by controlling the rotation speed of the geared motor 12, thereby driving the metal drum 1 and the plastic drum 5 to rotate at a certain speed under the support of the first support wheel seat 9 and the second support wheel seat 13. The spiral blades 17 inside the plastic drum 5 will stir, mix and transport the chemical raw materials that enter the plastic drum 5 through the feed box 14, so that the chemical raw materials can be fully mixed and reacted inside the plastic drum 5.

[0039] When the plastic drum 5 rotates as a whole, the elastic sealing gasket 22, which is located on the outer wall of the plastic drum 5 and is pressed and fixed on one side of the first sealing ring 21 by the second sealing ring 24, can block and seal the outer wall of the rotating plastic drum 5, preventing external gas from entering the plastic drum 5 through the gap between the plastic drum 5 and the insertion hole 20, and at the same time preventing the chemical raw materials and gas inside the plastic drum 5 from leaking out through the gap, thereby improving the sealing effect of the connection between the plastic drum 5 and the discharge box 6 and the feed box 14.

[0040] Meanwhile, the staff only needs to insert multiple elastic sealing gaskets 22, one side overlapping, between the second sealing ring 24 and the first sealing ring 21, such as... Figure 6-7 As shown, after aligning the first fixing holes 19 on the outer walls of two adjacent stacked elastic sealing gaskets 22, the two stacked elastic sealing gaskets 22 can be clamped and fixed between the first sealing ring 21 and the second sealing ring 24 by bolts. This allows multiple elastic sealing gaskets 22 to be overlapped and clamped and fixed on the outer wall of the connection between the plastic rotating cylinder 5 and the insertion hole 20. Thus, through multiple elastic sealing gaskets 22 tightly attached to the outer wall of the plastic rotating cylinder 5, the gap between the plastic rotating cylinder 5 and the insertion hole 20 can be effectively sealed without affecting the rotation of the plastic rotating cylinder 5 on the inner wall of the insertion hole 20.

[0041] like Figure 2-3 As shown, a feed pipe 16 is inserted into the outer wall of the feed box 14, an observation port 7 and a liquid outlet 10 are provided on the outer wall of the discharge box 6, and a waste discharge port 8 is provided on one side of the outer wall of the discharge box 6.

[0042] The discharge box 6 and the feed box 14 are respectively connected to exhaust pipes 15 on the top outer walls; the chemical raw material conveying pipeline is connected to the feed pipe 16, so that the chemical raw material is input into the plastic drum 5 through the feed pipe 16. After the chemical raw material is reacted inside the rotating plastic drum 5, it will move and gather to the side of the discharge port 7 under the push of the spiral blades 17, and then be discharged out through the liquid outlet 10. At the same time, the waste residue generated during the chemical reaction will accumulate on the side of the waste residue discharge port 8. The staff can open the waste residue discharge port 8 periodically to recycle the waste residue.

[0043] Waste gas generated during the mixing and reaction of chemical raw materials can be discharged to the outside through exhaust pipe 15.

[0044] Working principle: The rotational speed of the metal drum 1 and the plastic drum 5 is controlled by controlling the rotational speed of the geared motor 12. This drives the metal drum 1 and the plastic drum 5 to rotate at a constant speed under the support of the first support wheel seat 9 and the second support wheel seat 13. The spiral blades 17 inside the plastic drum 5 stir, mix and transport the chemical raw materials that enter the plastic drum 5 through the feed box 14, so that the chemical raw materials can be fully mixed and reacted inside the plastic drum 5.

[0045] Simply insert multiple elastic sealing gaskets 22, one side overlapping, between the second sealing ring 24 and the first sealing ring 21, as follows: Figure 6-7 As shown, after aligning the first fixing holes 19 on the outer walls of two adjacent stacked elastic sealing gaskets 22, the two stacked elastic sealing gaskets 22 can be clamped and fixed between the first sealing ring 21 and the second sealing ring 24 by bolts, thereby quickly overlapping and clamping multiple elastic sealing gaskets 22 on the outer wall of the connection between the plastic rotating cylinder 5 and the insertion hole 20.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
