when in use: when the rapid cooling pump stops working and the bottom plate part of the rapid cooling pump needs to be cleaned, the cylinder needs to be started, so that the sealing plate is moved to the lower side of the bottom plate, the cleaning part moves to the upper end of the bottom plate, the motor drives the driving gear to rotate under the driving of the motor, the inner gear teeth are driven to rotate through the connecting gear, the rotating sleeve can rotate relative to the first sleeve and the second sleeve, so that the cleaning part is driven to rotate, block dust on the bottom plate is cleaned, and finally the dust leaves the bottom plate through the dust falling groove; after cleaning is finished, the motor rotates the cleaning part to a position corresponding to the ash falling groove; the starting cylinder resets to drive the cleaning part to return to the initial position, and the sealing plate seals the ash falling groove again. The processes of the cleaning part ascending and the sealing plate descending are completely opposite to the processes of the cleaning plate descending and the sealing plate ascending, and only the former is taken as an example to briefly describe:
as shown in fig. 6: at first, cylinder upward movement to drive second dead lever upward movement, further drive first sleeve upward movement, thereby drive clean portion along constant head tank upward movement, what goes on simultaneously with this: because the cylinder drives the second sleeve to move upwards, and the bottom side mounting plate is fixedly connected relative to the bottom plate, the second hydraulic telescopic rod can be pulled to extend, because the inside of the compression cavity is relatively closed, the space of the compression cavity is fixed, when the second hydraulic telescopic rod extends, the first hydraulic telescopic rod can be driven to shorten so as to balance the space increment caused by the extension of the second hydraulic telescopic rod (in fact, in the downward movement process of the incomplete mounting ring, the first hydraulic telescopic rod moves due to the negative pressure generated in the compression cavity, and the raising process of the incomplete mounting ring completely provides power due to the hydraulic pressure of the liquid, under the condition that the cost is completely ignored and the reliability is improved, a driving part can be also mounted on the first hydraulic telescopic rod so that when the first hydraulic telescopic rod shortens, the driving part on the first hydraulic telescopic rod provides driving force, when the first hydraulic telescopic rod extends, the driving piece on the second hydraulic telescopic rod provides driving force (the air cylinder in the embodiment). ) (ii) a Therefore, when the cylinder extends, the main motion process of the rest motion parts is as follows: the extension of second hydraulic telescoping rod, simultaneously, first hydraulic telescoping rod shortens to lead to first sleeve upward movement, incomplete collar downstream respectively. Firstly, the incomplete mounting ring moves vertically downwards along the straight rail section of the guide rail on the action line of the fixture block (the side edge of the sealing plate is prevented from interfering with the side edge of the ash falling groove), and when the side edge of the sealing plate on the incomplete mounting ring is separated from being in contact with the side edge of the ash falling groove, the fixture block enters the spiral rail section of the guide rail to perform spiral descending movement; simultaneously, because sealed tube and adapter sleeve sliding connection, and through first dead lever, second dead lever and connecting rod fixed connection between first sleeve pipe and the second sleeve pipe, so second dead lever and lead a piece and be vertical upward movement, when the closing plate takes place to rotate for the axis of registration arm along the helical track section, for the cleaning part through falling grey groove motion to the bottom plate upside, when the scraper blade of cleaning part just contacted with the bottom plate upper surface, the cylinder moved extreme position promptly, and stop motion. The process of ascending the cleaning part and descending the sealing plate is completed.
According to the invention, the cleaning part is arranged outside the tank body, and the cleaning part is conveniently conveyed into the tank body in a mode of driving the ash removal shape by the air cylinder without influencing the working density of the tank body, so that the cleaning part can be effectively prevented from being polluted by dust of the tank body, and the manufacturing requirement that the cleaning part has to be improved due to the facing severe environment in the tank body can be avoided. Thereby greatly improving the use efficiency and the use stability of the cleaning part.
As a further scheme of the invention: the fixture block is a wheel-shaped block (shown in figure 9) which is rotatably arranged with the incomplete mounting ring. Because the turning part exists between the clamping block and the guide rail, the rolling wheel-shaped block is used, so that the abrasion of the clamping block can be greatly reduced.
As a further scheme of the invention: the ash falling groove is a dovetail groove with a small upper side and a large lower side, and the size of the sealing plate is matched with that of the ash falling groove. If the contact surface between the dust falling groove and the sealing plate is a side surface, the dust falling groove and the sealing plate are worn in long-term use, so that the sealing effect is reduced.
As a further scheme of the invention: the inner diameter of the first hydraulic telescopic rod is larger than that of the second hydraulic telescopic rod. In fact, in order to reduce the overall size of the device, the actual extension and retraction of the first hydraulic telescopic rod is smaller than that of the second hydraulic telescopic rod, so that the inner diameter of the first hydraulic telescopic rod is larger than that of the second hydraulic telescopic rod
As a further scheme of the invention: the first hydraulic telescopic rod, the second hydraulic telescopic rod and the base are made of heat-insulating materials. Reducing the rate of change of liquid volume caused by temperature differences.
As a further scheme of the invention: the lower end of the scraper is of a dense hairy structure, and the hairy structure can resist the machining error of a part of parts due to the fact that the hairy structure can be compressed.
Compared with the prior art, the invention has the beneficial effects that:
according to the invention, the cleaning part is arranged outside the tank body, and the cleaning part is conveniently conveyed into the tank body in a mode of driving the ash removal shape by the air cylinder without influencing the working density of the tank body, so that the cleaning part can be effectively prevented from being polluted by dust of the tank body, and the manufacturing requirement that the cleaning part has to be improved due to the facing severe environment in the tank body can be avoided. Thereby greatly improving the use efficiency and the use stability of the cleaning part.

as shown in fig. 6: first, the cylinder 14 moves upward to drive the second fixing rod 20 to move upward, and further to drive the first sleeve 21 to move upward, so as to drive the cleaning portion to move upward along the positioning slot 11, and at the same time: since the cylinder 14 supports the second sleeve 23 to move upward and the bottom mounting plate 26-5 is fixedly connected with respect to the bottom plate 4, the second hydraulic telescopic rod 24 will be pulled to extend, since the interior of the compression chamber 26-6 is relatively closed, the space of the compression chamber 26-6 is fixed, when the second hydraulic telescopic rod 24 extends, the first hydraulic telescopic rod 10 will be driven to shorten to balance the space increase caused by the extension of the second hydraulic telescopic rod 24 (in fact, during the downward movement of the incomplete mounting ring 27, the first hydraulic telescopic rod 10 moves due to the negative pressure generated in the compression chamber 26-6, and during the upward movement of the incomplete mounting ring 27, the hydraulic pressure of the fluid is completely used for power supply, and under the condition of improving the reliability due to the completely negligible cost, a driving member can be mounted on the first hydraulic telescopic rod 10, so that when the first hydraulic telescopic rod 10 is shortened, the driving member on the first hydraulic telescopic rod 10 provides driving force, and when the first hydraulic telescopic rod 10 is lengthened, the driving member on the second hydraulic telescopic rod 24 provides driving force (the air cylinder 14 in the embodiment). ) (ii) a Therefore, when the cylinder 14 extends, the main motion process of the rest of the moving parts is as follows: the second hydraulic telescopic rod 24 is extended while the first hydraulic telescopic rod 10 is shortened, thereby causing the first bushing 21 to move upward and the incomplete mounting ring 27 to move downward, respectively. Firstly, the incomplete mounting ring 27 moves vertically downwards along the straight rail section 12-1 of the guide rail 12 on the action line of the fixture block 25 (the side edge of the sealing plate 6 is prevented from interfering with the side edge of the ash falling groove 5), and when the side edge of the sealing plate 6 on the incomplete mounting ring 27 is separated from contacting with the side edge of the ash falling groove 5, the fixture block 25 enters the spiral rail section 12-2 of the guide rail 12 to perform spiral descending movement; meanwhile, as the sealing tube 3 is slidably connected with the connecting sleeve 2, and the first sleeve 21 is fixedly connected with the second sleeve 23 through the first fixing rod 15, the second fixing rod 20 and the connecting rod 16, the second fixing rod 20 and the connecting piece thereof both move vertically and upwards, when the sealing plate 6 rotates along the spiral track section 12-2 relative to the axis of the positioning tube 9, namely the cleaning part moves to the upper side of the bottom plate 4 through the ash chute 5, until the scraper 8 of the cleaning part just contacts with the upper surface of the bottom plate 4, namely the air cylinder 14 moves to the limit position and stops moving. That is, the process of ascending the cleaning portion and descending the sealing plate 6 is completed.
The cleaning part is arranged outside the tank body, and the cleaning part is conveniently conveyed into the tank body by driving the ash cleaning shape to be arranged through the air cylinder 14 under the condition of not influencing the working density of the tank body, so that the cleaning part can be effectively prevented from being polluted by dust of the tank body, and the manufacturing requirement that the cleaning part has to be improved due to the faced severe environment in the tank body can be avoided. Thereby greatly improving the use efficiency and the use stability of the cleaning part.
The latch 25 is a wheel-shaped latch rotatably disposed with the incomplete ring 27 (shown in fig. 9). Because the turning part exists between the fixture block 25 and the guide rail 12, the abrasion of the fixture block 25 can be greatly reduced by using a wheel-shaped block which can roll.
The ash dropping groove 5 is a dovetail groove with a small upper side and a large lower side, and the size of the sealing plate 6 is matched with that of the ash dropping groove. If the contact surface between the dust falling groove 5 and the sealing plate 6 is a side surface, it is worn in long-term use, and the sealing effect is reduced.
The inner diameter of the first hydraulic telescopic rod 10 is larger than that of the second hydraulic telescopic rod 24. In fact, in order to reduce the overall size of the device, the actual extension and retraction of the first hydraulic telescopic rod 10 is smaller than that of the second hydraulic telescopic rod 24, so that the inner diameter of the first hydraulic telescopic rod 10 is larger than that of the second hydraulic telescopic rod 24
The first hydraulic telescopic rod 10, the second hydraulic telescopic rod 24 and the base 26 are made of heat insulation materials. Reducing the rate of change of liquid volume caused by temperature differences.
The lower end of the scraper 8 is of a dense hairy structure which can resist the processing error of a part of parts because the hairy structure can be compressed.
The working principle is as follows: as shown in fig. 6: first, the cylinder 14 moves upward to drive the second fixing rod 20 to move upward, and further to drive the first sleeve 21 to move upward, so as to drive the cleaning portion to move upward along the positioning slot 11, and at the same time: since the cylinder 14 supports the second sleeve 23 to move upward and the bottom mounting plate 26-5 is fixedly connected with respect to the bottom plate 4, the second hydraulic telescopic rod 24 will be pulled to extend, since the interior of the compression chamber 26-6 is relatively closed, the space of the compression chamber 26-6 is fixed, when the second hydraulic telescopic rod 24 extends, the first hydraulic telescopic rod 10 will be driven to shorten to balance the space increase caused by the extension of the second hydraulic telescopic rod 24 (in fact, during the downward movement of the incomplete mounting ring 27, the first hydraulic telescopic rod 10 moves due to the negative pressure generated in the compression chamber 26-6, and during the upward movement of the incomplete mounting ring 27, the hydraulic pressure of the fluid is completely used for power supply, and under the condition of improving the reliability due to the completely negligible cost, a driving member can be mounted on the first hydraulic telescopic rod 10, so that when the first hydraulic telescopic rod 10 is shortened, the driving member on the first hydraulic telescopic rod 10 provides driving force, and when the first hydraulic telescopic rod 10 is lengthened, the driving member on the second hydraulic telescopic rod 24 provides driving force (the air cylinder 14 in the embodiment). ) (ii) a Therefore, when the cylinder 14 extends, the main motion process of the rest of the moving parts is as follows: the second hydraulic telescopic rod 24 is extended while the first hydraulic telescopic rod 10 is shortened, thereby causing the first bushing 21 to move upward and the incomplete mounting ring 27 to move downward, respectively. Firstly, the incomplete mounting ring 27 moves vertically downwards along the straight rail section 12-1 of the guide rail 12 on the action line of the fixture block 25 (the side edge of the sealing plate 6 is prevented from interfering with the side edge of the ash falling groove 5), and when the side edge of the sealing plate 6 on the incomplete mounting ring 27 is separated from contacting with the side edge of the ash falling groove 5, the fixture block 25 enters the spiral rail section 12-2 of the guide rail 12 to perform spiral descending movement; meanwhile, as the sealing tube 3 is slidably connected with the connecting sleeve 2, and the first sleeve 21 is fixedly connected with the second sleeve 23 through the first fixing rod 15, the second fixing rod 20 and the connecting rod 16, the second fixing rod 20 and the connecting piece thereof both move vertically and upwards, when the sealing plate 6 rotates along the spiral track section 12-2 relative to the axis of the positioning tube 9, namely the cleaning part moves to the upper side of the bottom plate 4 through the ash chute 5, until the scraper 8 of the cleaning part just contacts with the upper surface of the bottom plate 4, namely the air cylinder 14 moves to the limit position and stops moving. That is, the process of ascending the cleaning portion and descending the sealing plate 6 is completed.
