Description

Technical Field

[0001] The present application relates to the field of reactors, and in particular to a feeding device for a reactor. Background Art

[0002] Reactors are widely used in the fields of petroleum, chemical industry, rubber, pesticide, dye, medicine and food. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization and condensation, such as reactors, reaction pots, decomposition pots, polymerization kettles, etc.; the materials generally include carbon manganese steel, stainless steel, zirconium, nickel-based (Hastelloy, Monel, Inconel) alloys and other composite materials. When adding special materials into the reactor, they are generally fed through a feeding device.

[0003] Utility model patent publication number CN220405569U discloses a feed device for a reactor, comprising a feed barrel and a drying element. The bottom of the feed barrel is connected to the reactor body, a filter plate is connected to the feed barrel, and the feed barrel has a feed inlet. The feed barrel is also connected to a pressure rod and a rotating element, with the pressure rod located above the filter plate. The drying element reduces the moisture content of the feed barrel, thereby facilitating the pressure rod to crush the raw materials. The crushed raw materials then pass through the filter plate into the reactor, thereby reducing the amount of agglomerated raw materials entering the reactor and improving the reaction efficiency.

[0004] When the feeding device of the reactor is drying the material, the material is heated and dried by the hot air blower. The water vapor generated after the material is heated and dried will be accumulated in the feed barrel. When the material is relatively moist, more water vapor will accumulate in the feed barrel, which will affect the evaporation of moisture in the material, thereby reducing the drying effect of the hot air blower on the material. Utility Model Content

[0005] In order to enable the feeding device to have a better drying effect on the material, the present application provides a feeding device for a reactor.

[0006] The feeding device of a reactor provided in this application adopts the following technical solution:

[0007] A feeding device for a reactor comprises a feeding barrel for feeding materials into the reactor, a feeding port and a closing door for closing the feeding port being provided at the upper end of the feeding barrel, a blocking member for closing the feeding barrel being provided at the lower end of the feeding barrel, a hot air blower being provided on the feeding barrel, an upwardly inclined air outlet pipe being provided on the side wall of the feeding barrel, and a drying box being provided at the upper end of the air outlet pipe.

[0008] By adopting the above technical solution, the operator first opens the closed door, closes the lower end opening of the feed barrel by the blocking member, and after putting the material into the feed barrel, the operator closes the closed door and turns on the hot air blower. The air containing more water vapor generated by the hot air blower in the process of drying the material is discharged through the air outlet pipe. The water vapor contained in the air is absorbed by the drying box, so that the moisture content of the air in the feed barrel is maintained within a low range, so that the feeding device has a better drying effect on the material.

[0009] Optionally, a vertical drying tube is provided at the upper end of the air outlet duct, and the drying box is connected to the drying tube by sliding in the vertical direction. Horizontal indicator rods are provided at both ends of the drying box, and the indicator rods extend out of the drying tube in the horizontal direction. A sliding groove for moving the indicator rod is provided on the side wall of the drying tube, and an elastic member for maintaining the position of the drying box in the vertical direction is provided in the drying tube.

[0010] By adopting the above technical solution, as the drying box absorbs water, the weight of the drying box will increase and press the elastic member downward. When the drying box moves downward, the indicator rod will also move downward. The operator can easily judge the amount of water absorbed by the drying box by the up and down position of the indicator rod, so as to replace the drying box in time.

[0011] Optionally, the indicator rod is threadedly connected to the drying box.

[0012] By adopting the above technical solution, when installing the drying box in the air outlet duct, the operator first places the drying box in the air outlet duct, and then passes the indicator rod through the sliding groove and connects it to the drying box thread. This installation method is more convenient for assembly and disassembly.

[0013] Optionally, the elastic member includes a spring and a support plate, the spring is vertically arranged in the drying tube, the support plate is horizontally arranged at the upper end of the spring, and the upper end of the support plate is tightly arranged against the lower end of the drying box.

[0014] By adopting the above technical solution, the support plate is used to support the drying box. When the mass of the drying box increases, the spring is compressed, causing the drying box to move downward.

[0015] Optionally, a connecting plate is provided at one end of the closed door away from the feed barrel, a clamping block is provided at one end of the connecting plate facing the feed barrel, and a clamping groove for clamping with the feed barrel is provided at the upper end of the feed barrel.

[0016] By adopting the above technical solution, when closing the closed door, the disassembly and assembly personnel insert the block on the connecting plate into the slot on the feed barrel, so that the block is fixed, thereby fixing the closing plate and closing the upper end of the feed barrel.

[0017] Optionally, a contact electrode is provided at the lower end of the connecting plate, and a connecting electrode is provided at the upper end of the feed barrel. When the closing plate closes the feed port, the contact electrode and the connecting electrode are arranged to conflict with each other. The connecting electrode is electrically connected to the hot air blower and the hot air blower is energized when the connecting electrode and the contact electrode conflict with each other.

[0018] By adopting the above technical solution, after the closed door is closed, the contact electrode and the connecting electrode interfere with each other, so that the hot air blower is powered on and starts working, so that the feed barrel is in a closed state when the hot air blower dries the material, reducing the occurrence of dust being blown up by the hot air blower.

[0019] Optionally, a horizontal filter plate is provided in the feed barrel.

[0020] By adopting the above technical solution, the filter plate plays a role in filtering materials, thereby reducing the occurrence of agglomerated materials falling into the reactor.

[0021] Optionally, the blocking member includes a baffle and a drive motor, the drive motor is installed on the outer wall of the feed barrel, the drive shaft of the drive motor extends into the feed barrel in the horizontal direction, and the baffle is arranged at one end of the drive shaft of the drive motor located in the feed barrel.

[0022] By adopting the above technical solution, the driving motor drives the baffle to rotate, and the baffle causes the lower end of the feed barrel to be opened or closed when rotating. The operation of this structure is relatively convenient.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The air containing more water vapor generated by the hot air blower in the process of drying the material is discharged through the air outlet pipe. The water vapor in the air is absorbed by the drying box, so that the moisture content of the air in the feed barrel is maintained in a low range, so that the feeding device has a better drying effect on the material;

[0025] 2. The operator can easily judge the amount of water absorbed by the drying box by the up and down position of the indicator rod, so as to replace the drying box in time;

[0026] 3. When the hot air blower is drying the material, the feed barrel is in a closed state to reduce the occurrence of dust being blown up by the hot air blower. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The present application embodiment discloses a feeding device for a reactor. Figure 1 、 Figure 2 as well as Figure 3 A feeding device for a reactor includes a feeding barrel 2 for feeding materials into a reactor 1, a feeding port 21 is provided at the upper end of the feeding barrel 2, and a closing door 3 for closing the feeding port 21 is rotatably connected to the upper end of the feeding barrel 2, and a connecting plate 31 is fixedly connected to the end of the closing door 3 away from the feeding barrel 2, and a clamping block 32 is fixedly connected to the end of the connecting plate 31 facing the feeding barrel 2, and a slot 22 for clamping with the clamping block 32 is provided at the upper end of the feeding barrel 2. When the clamping block 32 is clamped in the slot 22, the closing door 3 is in a state of closing the feeding port 21.

[0035] Reference Figure 1 、 Figure 2 as well as Figure 3 A hot air blower 5 for blowing air into the feed barrel 2 is installed at the upper end of the feed barrel 2, a contact electrode 33 is installed at the lower end of the connecting plate 31, and a connecting electrode 23 is installed at the upper end of the feed barrel 2. When the closing plate closes the feed port 21, the contact electrode 33 is arranged to conflict with the connecting electrode 23. The connecting electrode 23 is electrically connected to the hot air blower 5 and when the connecting electrode 23 conflicts with the contact electrode 33, the hot air blower 5 is energized, so that the feed barrel 2 is in a closed state when the hot air blower 5 is drying the material, reducing the occurrence of dust being blown up by the hot air blower 5.

[0036] Reference Figure 1 as well as Figure 4A horizontal filter plate 24 is installed on the inner wall of the feed barrel 2. The filter plate 24 is used to intercept the agglomerated material to make the material particles put into the reactor 1 finer. A blocking member 4 is installed on the feed barrel 2 for closing the lower end of the feed barrel 2. The blocking member 4 includes a drive motor 41 and a baffle 42. The drive motor 41 is installed on the outer wall of the feed barrel 2. The drive shaft of the drive motor 41 extends into the feed barrel 2 in the horizontal direction. The baffle 42 is fixedly connected to one end of the drive shaft of the drive motor 41 located in the feed barrel 2. When the baffle 42 rotates to a horizontal state, the lower end of the feed barrel 2 is closed, which plays a role in blocking the material.

[0037] Reference Figure 2 、 Figure 4 as well as Figure 5 An air outlet pipe 6 is installed on the side wall of the feed barrel 2 in an oblique upward direction, and a vertically upward drying pipe 7 is installed on the upper end of the air outlet pipe 6. An elastic member 9 is installed on the inner wall of the drying pipe 7. The elastic member 9 includes a spring 91 and a support plate 92. A horizontal mounting plate 93 is fixedly connected to the inner wall of the drying pipe 7. The spring 91 is installed on the upper end of the mounting plate 93 in the vertical direction, and the support plate 92 is horizontally connected to the upper end of the spring 91. The drying box 8 is placed on the upper end of the support plate 92. Both ends of the drying box 8 in the horizontal direction are threadedly connected with an indicator rod 81. A vertical sliding groove 71 is opened on the side wall of the drying pipe 7. The indicator rod 81 passes through the sliding groove 71 and extends out of the drying pipe 7. When the drying box 8 moves up and down, the indicator rod 81 moves up and down along the sliding groove 71.

[0038] The implementation principle of the feeding device of a reactor 1 in an embodiment of the present application is: the operator first rotates the baffle 42 to a horizontal state by driving the motor 41 to close the lower end of the feed barrel 2, and then opens the closed door 3 to add materials into the feed barrel 2 from the feed port 21. After the addition is completed, the card block 32 is inserted into the card slot 22 so that the closed door 3 closes the feed barrel 2 and the contact electrode 33 conflicts with the connection electrode 23, so that the hot air blower 5 is energized and blows hot air into the feed barrel 2 to dry the material.

[0039] The hot air with a high water content generated when the material is dried is discharged into the atmosphere through the air outlet pipe 6 and the drying pipe 7. The drying box 8 is used to absorb moisture in the hot air, so that a relatively dry environment is maintained in the feed barrel 2, thereby improving the drying effect of the hot air blower 5 on the material. As the equipment is used, the drying box 8 absorbs moisture and its mass increases, compressing the spring 91 downward. When the spring 91 is compressed and shortened, the drying box 8 moves downward. When the drying box 8 moves downward, it drives the indicator rod 81 downward. The operator can judge the water absorption condition of the drying box 8 by the distance the indicator rod 81 moves downward, and thus replace the drying box 8 in time.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
