Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coking inhibitor preparation, and specifically relates to a coking inhibitor preparation device. BACKGROUND

[0002] The coking inhibitor is used for preventing and treating the problems of boiler coking and ash deposition. When the coking inhibitor is prepared, a mixing device is often needed to mix multiple materials. The problems of coking and ash deposition often occur in the use of a boiler, and the reasons for coking mainly include insufficient air supply or insufficient air mixing during combustion, so that carbon monoxide is generated, the ash melting point is greatly reduced, the flame is deflected, the boiler is overloaded, and the problem of boiler coking reduces the efficiency of the boiler and exists a safety hazard. At present, the coking inhibitor is one of the main ways to prevent and treat the problems of boiler coking and ash deposition.

[0003] A boiler coking inhibitor and a preparation method thereof are provided in a Chinese patent with the authorized announcement number CN110982579B. The melting temperature of coal ash is increased by adding heavy oil into the inhibitor, a brittle powder-like low-adhesion furnace ash is formed, and the furnace ash is easy to clean. However, the existing coking inhibitor preparation device often mixes multiple materials in a rotary stirring manner through a stirring rod when the coking inhibitor is prepared. The caking phenomenon easily occurs in stirring, so that the multiple materials in the stirring barrel cannot be fully combined, thereby greatly reducing the use effect of the inhibitor after mixing, affecting the production efficiency, and being not conducive to actual use.

[0060] In another embodiment, the first stirring rod 207 is provided with a plurality of first protrusions 2072 on the side close to the first through hole, and the plurality of first protrusions 2072 are uniformly distributed along the length direction of the first stirring rod 207. The second stirring rod 208 is provided with a plurality of second protrusions 2082 on the side close to the second through hole, and the plurality of second protrusions 2082 are uniformly distributed along the length direction of the second stirring rod 208.

[0061] When the first stop block 2078 and the second stop block 2088 gradually approach each other, the first stop block 2078 and the second protrusion 2082 reciprocally collide, and the second stop block 2088 and the first protrusion 2072 reciprocally collide, and the space between the first stirring rod 207 and the second stirring rod 208 continuously expands and shrinks in a small range. The liquid continuously enters and exits the space between the first stirring rod 207 and the second stirring rod 208, so that the substances in the gap between the first stirring rod 207 and the second stirring rod 208 can be carried out by the liquid flowing into the gap after being rubbed apart, thereby preventing re-agglomeration.

[0062] In another embodiment, the first stirring mechanism further comprises a third spring, one end of the third spring being fixedly connected to the first movable plate 2074, and the other end of the third spring being fixedly connected to the inner wall of the first mounting groove. The second stirring mechanism further comprises a fourth spring, one end of the fourth spring being fixedly connected to the second movable plate 2084, and the other end of the fourth spring being fixedly connected to the inner wall of the second mounting groove.

[0063] When the first stirring rod 207 is in the first state, the first block 2078 completely extends out of the first through hole and the second block 2088 completely extends out of the second through hole under the action of the third spring and the fourth spring. When the first stirring rod 207 is in the second state, the first block 2078 and the adjacent second stirring rod 208 tightly abut under the action of the third spring and the fourth spring, and the second block 2088 and the adjacent first stirring rod 207 tightly abut.

[0064] In another embodiment, the upper end surface of the stirring barrel 100 is provided with a feeding port 103, and the lower end surface of the stirring barrel 100 is provided with a discharging port 104. After stirring is completed, the discharging port 104 is opened, and the material is discharged from the discharging port 104.

[0065] Working process: in the initial state, the first spring 2073 and the second spring 2083 are in the original length, the distance between the plurality of first stirring rods 207 is maximum, and the distance between the plurality of second stirring rods 208 is maximum.

[0066] Start the first motor 201 and the second motor 202, the first motor 201 rotates to drive the first rotating shaft 205 to rotate, and drives the third rotating shaft 209 to rotate through the cross bar, the third rotating shaft 209 rotates to drive the first stirring mechanism to rotate synchronously. The second motor 202 rotates to drive the second rotating shaft 206 to rotate, the second rotating shaft 206 rotates to drive the fourth rotating shaft 2010 to rotate, and the fourth rotating shaft 2010 rotates to drive the second stirring mechanism to rotate synchronously.

[0067] First, the first motor 201 and the second motor 202 rotate in the same direction, the first stirring mechanism and the second stirring mechanism rotate in the same direction, and the material in the stirring barrel 100 is stirred. At this time, due to the action of the first spiral spring 2071 and the second spiral spring 2081, the first stirring rod 207 will not rotate around the third rotating shaft 209, and the second stirring rod 208 will not rotate around the fourth rotating shaft 2010.

[0068] When the stirring is performed for a period of time, the first motor 201 and the second motor 202 are relatively rotated, and then drive the first stirring mechanism and the second stirring mechanism to relatively rotate. At the same time, the hydraulic push cylinder 203 is started, the extension end of the hydraulic push cylinder 203 is extended, drives the pressing ring 204 to move downward, and the pressing ring 204 drives the plurality of first springs 2073 and the plurality of second springs 2083 to contract, so that the gap between the two adjacent first stirring rods 207 is reduced, and the gap between the two adjacent second stirring rods 208 is reduced.

[0069] At this time, the relative rotation of the first stirring rod 207 and the second stirring rod 208 causes the agglomerated material in the stirring barrel 100 to gather together, i.e. the agglomerated material gathers in the space surrounded by the plurality of first stirring rods 207, the plurality of second stirring rods 208 and the stirring barrel 100. When the first stirring rod 207 meets the second stirring rod 208, as shown in Fig. 16, the first stopper 2078 abuts against the adjacent second stirring rod 208, and the second stopper 2088 abuts against the adjacent first stirring rod 207, at this time, the agglomerated material is located between the first stirring rod 207 and the second stirring rod 208. Figure 8

[0070] After the first stirring mechanism and the second stirring mechanism contact, the relative rotation of the first motor 201 and the second motor 202 causes the first stirring rod 207 to rotate relative to the third rotation shaft 209, and the second stirring rod 208 to rotate relative to the fourth rotation shaft 2010, at this time, the first spiral spring 2071 and the second spiral spring 2081 start to store energy. The first stirring mechanism and the second stirring mechanism continue to rotate relative to each other, the extension amount of the first stopper 2078 and the second stopper 2088 gradually decreases, and the gap between the first stirring rod 207 and the second stirring rod 208 further decreases, thereby increasing the rubbing effect on the agglomerated material in the gap.

[0071] And the first stirring mechanism and the second stirring mechanism continue to rotate relative to each other, so that the first stirring rod 207 and the second stirring rod 208 move relative to each other, the direction of the relative movement is along the length direction of the first stirring rod 207 and the second stirring rod 208, as shown in Fig. 17. The first stopper 2078 and the second stopper 2088 gradually approach each other, and the first stopper 2078 and the second stopper 2088 gather the agglomerated material between the first stirring rod 207 and the second stirring rod 208 together, thereby preventing the edge position from rubbing for a short time and failing to rub apart. Figure 11

[0072] Figure 14 The direction of the arrow in the middle represents the flow direction of the liquid. When the first stopper 2078 and the second stopper 2088 gradually approach each other, the first stopper 2078 and the second protrusion 2082 reciprocally collide, and the second stopper 2088 and the first protrusion 2072 reciprocally collide, the space between the first stirring rod 207 and the second stirring rod 208 continuously expands and shrinks in a small range. The liquid continuously enters and exits the space between the first stirring rod 207 and the second stirring rod 208, so that the material in the gap between the first stirring rod 207 and the second stirring rod 208 can be taken out by the liquid flowing into the gap after being rubbed apart, thereby preventing the material from agglomerating again.

[0073] The above only describes the preferred embodiments of the present application and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.​​
