Description

Technical Field

[0001] This utility model relates to the field of chemical equipment, and in particular to a feeding device for a solid powder material reactor. Background Technology

[0002] In chemical production, many production units require distillation or reflux with water removal before adding solid powdered materials (in drums or bags) to the reactor in the presence of organic solvents for the next reaction operation. Current production processes typically involve directly using suction pipes to draw the solid powdered material from the drums / bags into the reactor, or installing specialized solid feeders. However, if suction is used, personnel at the feeding site may come into contact with the material, affecting their occupational health. Furthermore, at the end of suction, residual material in the pipes needs to be drawn into the reactor, resulting in a small amount of air being drawn in. Installing specialized feeder equipment involves significant investment and requires substantial plant space. Utility Model Content

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figure 1-2 As shown, a solid powder material feeding device for a reactor includes a housing 1. The front side wall of the housing 1 has a viewing window 3 and two operating ports 4. Long gloves 11 are provided at the operating ports 4 for easy access into the housing 1. The gloves are made of soft leather and non-breathable fabric. A door 2 is provided on the right side wall of the housing 1 for easy opening to place material buckets or bags. A sealing strip is provided at the door for sealing. The top of the housing 1 has a material extraction port 7, a vent port 8, and a nitrogen port 9. These ports are connected to corresponding quick-connect ports on the reactor. The interior of the housing 1 contains… The material extraction pipe 12 is connected to the extraction port 7. The material extraction pipe 12 is a telescopic flexible hose. A pull rod 10 is inserted into the top of the box body 1. A sealing ring is provided at the point where the pull rod is inserted into the top of the box body. The lower end of the pull rod 10 is connected to the lower end of the material extraction pipe 12. The material extraction pipe can be inserted into the material by pulling the pull rod. At the same time, the pull rod can control the insertion depth of the material extraction pipe. The bottom of the box body 1 is provided with a ramp 13 that slopes downward from left to right. The ramp tilts the bottom of the material bucket or material bag, which facilitates the suction of the material near the bottom. The bottom of the box body 1 is provided with casters 14 to facilitate the movement of the box body.

[0029] For example, the inclination angle of ramp 13 is 15-30°.

[0030] For example, the operating port 4 is also provided with a sealing cover 5, and the sealing cover 5 is provided with a sealing gasket 6 for sealing.

[0031] For example, two vertically arranged sleeves 15 are provided on the rear side wall of the housing 1, and an n-shaped push rod 16 is inserted into the sleeve 15. The push rod is used to facilitate pushing the housing, and the push rod can move up and down inside the sleeve. When the push rod is not in use, it is pushed into the sleeve and will not obstruct other operations.

[0032] For example, such as Figure 3 The diagram shows the internal structure of another solid powder material reactor feeding device. The ramp 13 is also equipped with a support mechanism 18 for material buckets or material bags to prevent the material buckets or material bags from tipping over.

[0033] Specifically, such as Figure 4 As shown, the support mechanism 18 includes two sliding members that slide relative to each other; the sliding members include a slide block 19, a vertical rod 20, an arc-shaped stop bar, an extension rod 22, an arc-shaped support rod 23, a locking post 24, a first fastening bolt 25, and a second fastening bolt 26;

[0034] The ramp 13 is provided with a groove 17 to facilitate the sliding of two sliding parts. The slide seat 19 is slidably disposed in the groove 17. A first fastening bolt 25 for fixing the slide seat 19 is screwed onto the slide seat 19. A vertical pole 20 is provided on the slide seat 19. An arc-shaped stop bar 21 is provided on the pole 20. An extension rod 22 is vertically slidably inserted into the pole 20. An arc-shaped support rod 23 is provided at the top of the extension rod 22. Two locking pins 24 are provided on the support rod. A second fastening bolt 26 for fixing the extension rod 22 is screwed onto the side wall of the pole 20.

[0035] The sliding mechanism allows for adjustment of the distance between the sliding parts, making it suitable for material buckets or bags of different sizes. The arc-shaped stop bar is used to block the side wall of the material bucket or bag. The arc-shaped support rod and the locking post are used to fix the top of the material bag. After the material bag is opened, the top can be wrapped around the arc-shaped support rod, while the locking post is locked at the top edge of the material bag, thus supporting the bag opening and facilitating the suction of materials.

[0036] For example, box 1 is a rectangular box with a length of 120-140cm, a width of 80-90cm, and a height of 120-140cm. Specifically, in this embodiment, the length is 130cm, the width is 80cm, and the height is 130cm.

[0037] For example, the diameter of the operating port 4 is 14-16 cm. Specifically, in this embodiment, the diameter is 15 cm.

[0038] Workflow:

[0039] 1. First, place the unopened barrelled (or bagged) solid powder material onto the slope inside the box.

[0040] 2. Connect the feed inlet, vent, and nitrogen inlet of the feeding box to the corresponding quick-connect ports on the reactor, as shown in the diagram. Figure 5 As shown. A pressure gauge can also be installed on the chamber to detect the internal pressure.

[0041] 3. First, replace the air in the extraction box by using nitrogen gas and venting in the reactor.

[0042] 4. After the replacement is completed, vent the material extraction box to normal pressure through the venting pipe. After the venting of the material extraction box is closed, open the barrel lid or packaging bag inside the material extraction box through the operating port.

[0043] 5. Use the lever on top of the extraction box to insert the extraction tube into the material bucket or material bag.

[0044] 6. Open the material extraction valve of the reactor (which is under negative pressure) to extract the material. The sealing cover should be closed during nitrogen purging and material extraction.

[0045] The feeding process involves zero contact between personnel and materials, improving occupational health. It also offers high safety, as nitrogen purging eliminates contact with air during feeding.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
