Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Example 1: referring to fig. 1, a micro-porous reaction kettle comprises a kettle body 100, a feeding mechanism 200, a stirring mechanism 300 and a discharging mechanism 400. Wherein, the stirring mechanism 300 adopts a lower driving type, that is, the stirring driving member 310 (for example, a motor) is positioned below the kettle body 100; meanwhile, the bottom of the kettle body 100 is obliquely arranged on the basis of any kettle body structure in the prior art of the kettle body 100; the discharging mechanism 400 is disposed at the inclined lower position of the bottom of the kettle 100 on the basis of any discharging mechanism structure (including a discharging pipeline, a buffer, a discharging pump, etc.) in the prior art, so as to facilitate complete discharging.

The feeding mechanism 200 includes a first feeding pipe 210, a second feeding pipe 220, a feeding unit 230, an opening and closing unit 250 for closing or opening the feeding micro-hole 240, and a piston unit 260 disposed in the second feeding pipe 220. The first feeding pipe 210 may be any pipe used for feeding a main raw material (e.g., deionized water) in the prior art, one end of the first feeding pipe is communicated with a basic reaction raw material source, the other end of the first feeding pipe extends into the kettle body 100, one end of the second feeding pipe 220 is communicated with other reaction raw material sources, the other end of the second feeding pipe extends into the kettle body 100, and the first feeding pipe 210, the second feeding pipe 220 and the kettle body 100 are fixedly connected by welding.

The feeding unit 230 is a hollow structure, in this embodiment, the feeding unit 230 is a cylindrical, hollow, metal box structure, and the feeding unit 230 is located on the stirring blades 330 of the stirring unit 300, fixed to the lower end of the second feeding pipe 220 by welding, and communicated with the second paint pipe 220. The feeding unit 230 has a plurality of feeding micropores 240 formed on a surface thereof, in this embodiment, the feeding micropores 240 are formed on an outer peripheral sidewall of the feeding unit 230, in other embodiments, the feeding micropores 240 may be formed on an upper surface, a lower surface, or both of the upper surface and the lower surface of the feeding unit 230 in an annular array. The aperture of the feeding micro-holes 240 is 15mm-40mm (preferably 30 mm), and the arrangement interval (i.e. the minimum distance between the hole edges) between the adjacent feeding micro-holes 240 is not less than 20 mm.

The forming state of the piston unit 260 controls the working states of the second feeding pipe 220 and the opening and closing unit 250:

in an initial state, the piston unit 260 is in a recovery stroke, the piston unit 260 closes the second feeding pipeline 220, and controls the opening and closing unit 250 to close the feeding micro-hole 240;

in the filling state, the piston unit 260 is in the recovery state, and the piston unit 260 closes the second feeding pipe 220;

in the feeding state, the piston unit 260 is in the extending stroke, the piston unit 260 closes the second feeding pipe 220, and controls the opening and closing unit 250 to open the feeding micro-hole 240.

By means of the structure, the feeding unit 230 of the micropore reaction kettle can dispersedly feed other reaction raw materials to the middle part of the kettle body 100 by using the feeding micropores 240 formed on the feeding unit, and the reaction raw materials are further quickly diffused under the action of the stirring mechanism 300, so that the other reaction raw materials can be uniformly fed into the basic reaction raw materials, and the problems of over-quick local reaction, fluctuation of local pH value and local material agglomeration during material dripping are effectively solved; on the other hand, the piston unit 260 can control the second feeding pipeline 220 and the opening and closing unit 250, so that the functions of repeated filling and feeding are realized, and the requirement that various other reaction raw materials need to be sequentially fed in the process of manufacturing the dispersing agent is met; meanwhile, basic reaction raw materials and other reaction raw materials are fully stayed, stirred and reacted in the reaction kettle, so that the production requirement of the dispersing agent is met, and the kettle body 100 is based on the traditional kettle body structure, so that the production efficiency of the dispersing agent is ensured.

Specifically, the second feeding pipe 220 includes a second feeding pipe upper section 221 and a second feeding pipe lower section 222 which are communicated with each other, the second feeding pipe upper section 221 is communicated with a raw material source (other reaction raw material source), and has an inner diameter larger than that of the second feeding pipe lower section 222, and the second feeding pipe lower section 222 is communicated with the feeding unit 230; the piston unit 260 includes a piston head 261 that mates with the inner diameter of the second feed conduit lower section 222, and a piston drive 262 (e.g., a piston rod) that drives the piston head 261 to move within the second feed conduit 220. Thus, when the piston head 261 travels to the second feeding conduit lower section 222, the second feeding conduit 220 is in a closed state; when the piston head 261 travels to the second feeding pipe upper section 221, the second feeding pipe 220 is in an open state.

As shown in fig. 2 and 3, the opening and closing unit 250 includes a plug 251 disposed to cooperate with the feeding micro-hole 240, a first stopper 252 for preventing the plug 251 from entering the feeding unit 230, and a second stopper 253 for preventing the plug 251 from leaving the feeding unit 230. In the present embodiment, the plug body 251 is a tapered plug, and the tapered top surface of the plug body 251 is disposed toward the inside of the feeding unit 230. The diameter of the conical bottom surface of the plug body 251 is larger than the aperture of the feeding micro-hole 240, so that the plug body 251 can seal the feeding micro-hole 240; the diameter of the conical top surface of the plug body 251 is 5mm-10mm smaller than the aperture of the feeding micro-hole 240, so that when the plug body 251 cancels the sealing of the feeding micro-hole 240, a feeding gap with d =5mm-10mm can be formed. The feeding speed of the other reaction materials can be controlled by matching the feeding speed of the piston head 261 with the feeding gap. The first blocking member 252 and the second blocking member 253 are respectively and fixedly arranged on the tapered bottom surface of the plug body 251 and the tapered top surface of the plug body 251. To avoid accidents, the plugs 251 leave the feeding unit 230 and enter the kettle 100, and preferably, the first stoppers 252 of the adjacent plugs 251 are connected, and the second stoppers 253 of the adjacent plugs 251 are connected. In this case, the first stopper 252 and the second stopper 253 may be connecting bands that are fixed to the plug body 251 by an integral molding process and made of the same material as the plug body 251.

In a preferred embodiment, a plurality of secondary feed pipes 270 are provided in the second feed pipe upper section 221. In this case, the plurality of secondary feeding pipes 270 correspond to one of the other reaction materials.

The working flow of the micropore reaction kettle of the embodiment is as follows:

referring back to fig. 1, in the initial state, the piston unit 260 is in the recovery stroke, that is, the piston driving member 262 controls and drives the piston head 261 to move in the second feeding pipe lower section 222, and the piston head 261 is recovered from the maximum extension amount (the set stroke first node) to the minimum extension amount (the set stroke second node), at this time, the piston unit 260 closes the second feeding pipe 220, and the feeding micropores 240 are closed by controlling the opening and closing unit 250 (that is, the plugs 251 are plugged into the feeding micropores 240) with the vacuum pumping in the second feeding pipe lower section 222, and at the same time, the first feeding pipe 210 introduces the basic reaction raw materials into the kettle 100;

referring to fig. 4, in the packing state, the piston unit 260 finishes the recycling stroke and is in the recycling state, at this time, the piston head 261 is located in the second feeding pipe upper section 221, and since the inner diameter of the second feeding pipe upper section 221 is larger than that of the second feeding pipe lower section 222, at this time, the piston unit 260 opens the second feeding pipe 220, and due to the pressure of the existing basic reaction raw materials in the kettle body 100 on the side wall of the feeding unit 230, the opening and closing unit 250 still closes the feeding micropores 240, so that the first other reaction raw materials can be fed into the feeding unit 230 through the second feeding pipe upper section 221 or the plurality of secondary feeding pipes 270 arranged in the second feeding pipe upper section 221;

referring to fig. 5, in the feeding state, the piston unit 260 is in the extending stroke, the piston body 261 enters the second feeding pipe lower section 222 again, at this time, the piston unit 260 closes the second feeding pipe 220, the opening and closing unit 250 is controlled by the extrusion pressure to open the feeding micropores 240, and the first other reaction raw material is continuously fed into the kettle 100;

when the first other reaction raw materials in the feeding unit 230 are exhausted, the piston unit 260 is in the recovery stroke again, the opening and closing unit 250 closes the feeding micropores 250 again through vacuum pumping, and the steps are repeated to realize multiple times of feeding. Since the feeding gap is controlled to be 5mm-10mm and the tapered bottom surface of the tapered plug 251 is disposed outward, the feeding micro-holes 240 can be closed before the reaction raw materials in the kettle 100 are poured into the feeding unit 230.

Example 2: example 2 differs from example 1 in that, referring to fig. 6 and 7, the feeding unit 230 includes a plurality of sub-feeding chambers 232 independently arranged from each other, for example, in this embodiment, 4 sub-feeding chambers 232 with the same shape are included, and 4 sub-feeding chambers 232 can form a pie-shaped feeding unit 230. Each sub-feeding chamber 232 is fixed to the lower portion of the second feeding pipe 220 by welding, and an opening is formed in the upper surface of the portion of the sub-feeding chamber located in the space of the second feeding pipe 220.

The secondary feed pipe 270 in this embodiment extends into communication with the secondary feed chamber 232. Specifically, the number of the secondary feeding pipes 270 is the same as that of the sub-feeding chambers 232, and the secondary feeding pipes are corresponding to the sub-feeding chambers 232 one by one, extend to the sub-feeding chambers 232, communicate with the openings of the sub-feeding chambers 232, and are fixedly connected and sealed by using sealing gaskets or welding connection. The piston head 261 is provided with a through hole for the secondary feeding pipe 270 to pass through, and the sealing treatment between the through hole and the stimulating feeding pipe 270 can be any one of the prior art as long as the connection part of the piston head 261 and the stimulating feeding pipe 270 can be sealed and the sliding movement between the piston head 261 and the secondary feeding pipe 270 is not influenced. Therefore, the feeding of various other reaction raw materials is independent, and compared with the technical scheme of the embodiment 1, the method can avoid the influence on the next fed other reaction raw materials caused by the residue of the last fed other reaction raw materials, thereby influencing the reaction process.

Example 3: embodiment 3 differs from embodiment 1 in that, as shown in fig. 8 and 9, in the present embodiment, the charging unit 230 includes a main charging chamber 231, a plurality of (e.g., 4) sub charging chambers 232 respectively communicating with the main charging chamber 231, and the main charging chamber 231 is a disk-shaped hollow metal member, and the upper surface thereof is relatively rotatably mounted on the lower portion of the second charging pipe 220 through a rolling bearing and communicates with the second charging pipe 220. The lower portion thereof has a recessed table which is keyed with the stirring drive shaft 320 of the stirring mechanism 300 so that the stirring drive shaft 320 can drive the main charging chamber 231. The sub-charging chamber 232 is a long rectangular hollow metal plate, one end of which is welded and fixed to the outer peripheral side wall of the main charging chamber 231, and the sub-charging chamber 232 is disposed to rotate by a certain angle (for example, 45 °) with the axis thereof as an axis. At this time, the sub-feeding chamber 232 also serves as a part of the stirring mechanism 300, and the stirring driving member 310 drives the sub-feeding chamber 232 to rotate through the stirring driving shaft 320, so that other reaction materials can be further uniformly fed into the kettle body 100.

In this embodiment, the feeding holes 240 may be opened on the end wall, both side walls, and the back surface in the stirring direction of the sub-feeding chamber 232. However, the front side in the stirring direction should not be an opening side for opening the feeding micro-holes 240. For example, the sub-feeding chamber 232 rotates clockwise, and the sub-feeding chamber 232a serves as a front surface of the stirring direction and faces the reaction material in the kettle 100 during rotation, so that the feeding micropores 240 are easily blocked.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
