Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
The present embodiment provides a feeding device, as shown in fig. 1-7, comprising a connecting member 11, a rotating assembly 12, a tube sleeve 13, a rigid feeding tube 14 and a soft feeding tube 15;
a mounting hole is formed in the connecting piece 11, the rotating assembly 12 is located in the mounting hole and connected with the connecting piece 11, the pipe sleeve 13 is fixedly connected with the rotating assembly 12, the hard feeding pipe 14 is located in the pipe sleeve 13 and connected with the pipe sleeve 13, the rotating assembly 12 further drives the hard feeding pipe 14 to rotate through the pipe sleeve 13, and the soft feeding pipe 15 is communicated with one end of the hard feeding pipe 14.
When the feeding device is used, the feeding device is arranged on the reactor through the connecting piece 11, materials enter the hard feeding pipe 14 from the soft feeding pipe 15, and because the hard feeding pipe 14 is positioned in the pipe sleeve 13 and connected with the pipe sleeve 13, the pipe sleeve 13 is fixedly connected with the rotating assembly 12, and the rotating assembly 12 drives the hard feeding pipe 14 to rotate through the pipe sleeve 13, the conversion of the feeding angle can be realized through rotating the rotating assembly 12.
In addition, the connecting member 11 of this embodiment is for fixing the rotating assembly 12, and for connecting the feeding device of this embodiment to a reactor (e.g. a reaction kettle).
The soft material feeding pipe 15 is not only used for feeding materials into the hard material feeding pipe 14, but also used for ensuring that the hard material feeding pipe 14 is convenient to rotate when the feeding device of the embodiment is used.
The hard feeding pipe 14 can be made of a metal feeding pipe, such as a steel pipe, a titanium alloy pipe, etc., and is intended to smoothly rotate along with the pipe sleeve 13; the following problems may exist if the rigid feed tube 14 is made of a softer material: the hard feeding pipe 14 in the pipe sleeve 13 rotates, but the hard feeding pipe 14 outside the pipe sleeve 13 does not rotate, so that the hard feeding pipe 14 is bent, and the feeding speed is changed.
The rotation angle of the rotating assembly 12 in the present embodiment may be 15 ° to 18 °.
In a specific embodiment, the rotating assembly 12 includes a fixed portion 122 and a rotating portion 123, as shown in fig. 6(a), 6(b), 7(a) and 7(b), the rotating portion 123 is located in the fixed portion 122 and can rotate relative to the fixed portion 122, and the sleeve 13 is fixedly connected in the rotating portion 123.
Since the socket 13 is fixedly disposed in the rotating portion 123, a user can rotate the socket 13 by rotating the rotating portion 123 during use, and since the socket 13 is connected to the hard feeding pipe 14, a change in feeding angle is achieved.
It should be noted that the rotating portion 123 can be maintained in a certain angle after rotating to the certain angle because of the friction between the rotating portion 123 and the fixing portion 122.
In the exemplary embodiment, to facilitate coupling rotating assembly 12 to link 11, rotating assembly 12 further includes a housing 121; the housing 121 is connected to the connecting member 11, the fixing portion 122 is located between the housing 121 and the rotating portion 123, and the fixing portion 122 is fixedly connected to the housing 121.
In use, the housing 121 is connected, e.g. screwed, to the coupling member 11, thus assembling the coupling member 11 with the rotating assembly 12; since the connection member 11 is also connected to the reactor (e.g. a reaction kettle), the feeding device of the present embodiment is installed on the reaction kettle, wherein the screw connection is for easy assembly and disassembly.
In a particular embodiment, the rigid feed tube 14 is located within the sleeve 13 and is axially movable relative to the sleeve 13.
The feeding position is changed, for example, by manually pumping the rigid feeding pipe 14 to realize the movement of the rigid feeding pipe in the pipe sleeve 13, thereby changing the length of the rigid feeding pipe 14 in the reactor (for example, a reaction kettle).
In a particular embodiment, the feeding device further comprises a drive assembly 16, the drive assembly 16 being connected to the rigid feed tube 14 for axially moving the rigid feed tube 14 relative to the sleeve 13.
By activating the drive assembly 16, the rigid feed pipe 14 can be driven because the drive assembly 16 is connected to the rigid feed pipe 14 to effect movement of the rigid feed pipe within the tube housing 13 and thereby change the length of the rigid feed pipe 14 within the reactor (e.g., reaction vessel) and change the feed position.
For example, the drive assembly 16 is a motorized push rod that advances or retracts to effect axial movement of the rigid feed tube 14 relative to the tube housing 13.
In a particular embodiment, as shown in fig. 2(a), 2(b), and 3, the transmission assembly 16 includes a rack 161 and a pinion 162; the rack 161 is disposed along the axial direction of the hard feed tube 14 and is fixedly connected to the hard feed tube 14, and the gear 162 is engaged with the rack 161 to drive the hard feed tube 14 to move axially relative to the tube housing 13 by driving the rack 161.
In the present embodiment, the gear 162 may be manually rotated forward or backward; the gear 162 may be connected to an output shaft of the motor via a coupling shaft to drive the gear 162 in forward or reverse rotation.
When the gear 162 is rotated forward, the gear 161 moves backward to drive the hard feed pipe 14 to move backward because the gear 162 is meshed with the gear 161, as shown in fig. 3; when the gear 162 is reversed, the gear 162 is engaged with the rack 161, so that the rack 161 moves forward to move the hard material feeding pipe 14 forward, thereby achieving the axial movement of the hard material feeding pipe 14 relative to the pipe sleeve 13, further changing the length of the hard material feeding pipe 14 in the reactor (such as a reaction kettle), and changing the feeding position.
In a particular embodiment, as shown in FIGS. 2(a) and 2(b), the rack 161 is an annular rack that is fixedly secured to the rigid feed tube 14.
In a particular embodiment, rack 161 is disposed proximate to soft feed tube 15.
Since the soft material feeding pipe 15 is used to connect the device for containing the reaction materials with the hard material feeding pipe 14, the soft material feeding pipe 15 must be located outside the reactor (e.g. the reaction kettle), and the transmission component 16 needs to be located outside the reactor (e.g. the reaction kettle) for driving the transmission component 16, so the rack 161 needs to be arranged close to the soft material feeding pipe 15. In addition, when the length of the hard feeding pipe 14 is constant, the rack 161 is arranged close to the soft feeding pipe 15, so that a longer hard feeding pipe 14 can enter the reaction kettle, and the range of changing the feeding position is increased.
In a specific embodiment, the rigid feed tube 14 is advanced axially for a distance of 0mm to 500 mm; the axial retreating distance is 0 mm-500 mm. The specific distance is designed according to actual needs.
In a specific embodiment, a sealing filler is filled between the rigid feeding pipe 14 and the pipe sleeve 13; on one hand, the material in the reaction kettle is prevented from flowing back out of the reaction kettle from the gap between the hard feeding pipe 14 and the pipe sleeve 13; on the other hand, in order to reduce friction between the rigid feed tube 14 and the sleeve 13, the rigid feed tube 14 is easier to move axially within the sleeve 13; there are many materials that can seal water, such as silicone, plastic, etc.; in order to ensure that the friction between the rigid feed tube 14 and the sleeve 13 cannot be too great, it is necessary to apply a lubricant to the rigid feed tube for a particular application;
the number of the hard feeding pipes 14 is at least 2, and the two hard feeding pipes 14 are axially arranged in the pipe sleeve 13 in parallel;
because the number of the hard feeding pipes 14 is at least 2, the flow rate coverage can be enlarged by changing the pressure of the pump communicated with each hard feeding pipe 14 and further changing the flow rate of the material in each hard feeding pipe 14, so that the materials simultaneously entering the reaction kettle have different flow rates.
In addition, the pipe diameter of each hard feeding pipe 14 can be different, and the feeding device of the embodiment has a wider flow speed range by changing the pipe diameter.
The number of the rigid feed pipes 14 in this embodiment is 4, as shown in fig. 4(a), 4(b), 6(a), 6(b), 7(a) and 7 (b).
Meanwhile, since each hard feed tube 14 is connected to one drive assembly 16, each hard feed tube 14 can be located at a completely different feed position by driving the drive assembly 16.
A valve is arranged on the hose feeding pipe 15; whether or not to feed material into the rigid feed tube 14 communicating with the flexible tube feed tube 15 is controlled by opening or closing a valve.
In particular implementations, the rotating assembly 12 may also be a standard fisheye bearing.
Example 2
The present embodiment provides a reaction kettle, as shown in fig. 5-7, comprising a feeding device 1 of embodiment 1, and a reaction kettle body 2; the feeding device 1 is connected with the reaction kettle body 2.
Since the feeding device 1 of example 1 can change the feeding angle, the reaction kettle using the feeding device can also change the feeding angle, so that the feeding angle is diversified.
The procedure of example 2 is specifically described with reference to example 1:
firstly, the connecting piece 11 is arranged in a feeding port on the reaction kettle body 2 and is connected with the reaction kettle body 2, and can be in threaded connection, so that the disassembly is convenient; communicating a soft feeding pipe 15 with a device containing reaction materials;
then, the hard feeding pipe 14 is axially moved in the pipe sleeve 13 through the driving gear 162 and the meshed connection of the gear 162 and the rack 161, so as to change the height of the discharge port of the hard feeding pipe 14 from the bottom of the reaction kettle body 2, namely, change the feeding position; after the feeding position is adjusted, the hard feeding pipe 14 is rotated by rotating the rotating part of the rotating assembly 12, the feeding angle is changed, and the hard feeding pipe 14 reaches the expected position to finish the selection of the position of the hard feeding pipe 14 in the above adjustment;
finally, the valve on each soft feeding pipe 15 is opened, the pump communicated with the hard feeding pipe 14 is started, and the reaction materials enter the reaction kettle through the soft feeding pipe 15 and the hard feeding pipe 14, because 4 hard feeding pipes 14 are provided in the embodiment, the flow velocity of the materials in each hard feeding pipe 14 is different by changing the pressure of the pump or making the pipe diameter of each hard feeding pipe 14 different, thus realizing the simultaneous feeding in different flow ranges.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
