The overall device structure is simple and easy to slide and disassemble to replace the inner lining tank body for use; this patent is inconvenient to disassemble and is a closed type, which is inefficient for replacing the inner lining located inside. Summary of the invention

[0004] In view of the above technical problems, the present invention can solve the technical problem of inconvenient lining replacement, realize the lining installation on the outside, and then realize the installation by transfer, thus avoiding the problem of narrow operating space.

[0006] Furthermore, a lifting electric cylinder for driving the top cover to slide is fixedly installed on the outer side of the fixed cylinder, a feed hole is arranged on the top of the top cover, and a dispersion nozzle is arranged inside the top cover for dispersing and spraying liquid.

[0007] Furthermore, a second motor is fixedly mounted on the outer side of the fixed cylinder, a first gear is fixedly mounted on the output shaft of the second motor, and the first gear is used to drive the mating component.

[0008] Furthermore, a motor for driving the rotating drum to rotate is fixedly mounted on the outer side of the fixed drum.

[0024] like Figure 3 , Figure 4 and Figure 5 As shown, a replacement component is provided on the outer side of the fixed cylinder 1 for replacing the lining 5; the replacement component includes a slide seat 16 slidably arranged on the outer side of the fixed cylinder 1, and a transfer gear ring 13 is rotatably mounted on the slide seat 16; the replacement component also includes a slide rail 15 fixedly connected to the outer side of the fixed cylinder 1, and the slide seat 16 is slidably mounted on the slide rail 15, and a screw motor 12 is fixedly mounted on the slide rail 15, and a screw 14 is fixedly mounted on the output shaft of the screw motor 12, and the screw 14 and the slide seat 16 form a spiral pair; a motor three 17 is fixedly mounted on the slide seat 16, and a gear two 18 is fixedly mounted on the output shaft of the motor three 17, and the gear two 18 and the transfer gear ring 13 form a gear pair.

[0025] A matching component is provided on the liner 5, and the matching component includes an extrusion gear ring 24 rotatably mounted on the outside of the liner 5, and an extrusion arc plate 25 is fixedly mounted on the end face of the extrusion gear ring 24; the matching component also includes an extrusion rack 21 slidably mounted on the outside of the liner 5, and a support plate 20 rotatably mounted on the outside of the liner 5; the matching component also includes a fixing ring 19 fixedly connected to the liner 5, the support plate 20 is rotatably mounted on the fixing ring 19, the extrusion rack 21 is slidably mounted on the fixing ring 19, and one side of the support plate 20 is fixedly connected to a support plate gear 23, the support plate gear 23 and the extrusion rack 21 form a gear pair; a spring 22 for providing elastic force is arranged between one end of the extrusion rack 21 and the fixed ring 19, and a ball is arranged at the other end of the extrusion rack 21; when the extrusion gear ring 24 and the extrusion arc plate 25 rotate, and the extrusion arc plate 25 squeezes the extrusion rack 21, the support plate 20 deflects ninety degrees under the gear transmission; by rotating the transfer gear ring 13, and the transfer gear ring 13 cooperates with the socket on the support plate 20, the transfer gear ring 13 carries the liner 5 to move, so as to replace the liner 5.

[0026] The working principle of the present invention is as follows: when working, the raw materials are put into the material feeding port at the top of the top cover 4 and dispersed and sprayed through the dispersion nozzle 11, which is beneficial to reduce the impact on the lining 5; when replacing the lining 5, the top cover 4 is first controlled to rise by the lifting electric cylinder 10, and at the same time, the motor 6 drives the rotating drum 2 to rotate, so that the top cover 4 and the rotating drum 2 are separated from the fixed drum 1 respectively, so that the lining 5 located inside the fixed drum 1 is exposed; here, this embodiment adopts multi-drive to control the movement of the top cover 4 and the rotating drum 2 respectively. The technicians can set a gear transmission structure or a belt transmission structure here as needed to realize the joint movement of the rotating drum 2 and the top cover 4.

[0027] After the lining 5 is exposed, the gear 1 9 is first driven to rotate by the motor 2 8, and under the gear transmission, the extrusion gear ring 24 and the extrusion arc plate 25 rotate. When the extrusion arc plate 25 moves to the preset position, it can squeeze the end of the extrusion rack 21 provided with the ball, so that the extrusion rack 21 slides, which can reduce the contact friction; when the extrusion rack 21 slides, under the gear transmission, the support plate gear 23 and the support plate 20 rotate, and the support plate 20 rotates ninety degrees, that is, from a vertical state to a horizontal state. Since the support plate 20 is rotatably installed on the fixing ring 19, the rotation stroke of the support plate 20 on the fixing ring 19 is ninety degrees, that is, the fixing ring 19 can limit the rotation stroke of the support plate 20.

[0028] After the support plate 20 is in the horizontal state, the screw motor 12 drives the screw 14 to rotate. Under the connection of the spiral pair, the slide 16 slides, and the transfer ring gear 13 also moves with the slide 16. After moving to the preset position, the motor three 17 drives the gear two 18. Under the gear transmission, the transfer ring gear 13 rotates; when the transfer ring gear 13 rotates and one end of it cooperates with the socket on the support plate 20, the slide 16 continues to slide, so that the transfer ring gear 13 can carry the liner 5 to move, that is, to move the liner 5 out from the inner side of the fixed tube 1 to achieve disassembly. Similarly, the liner 5 needs to be assembled When it reaches the interior of the fixed cylinder 1, the liner 5 is placed on the transfer gear ring 13, and the liner 5 is transported to the interior of the fixed cylinder 1 through the transfer gear ring 13. The advantage of such an arrangement is that when the liner 5 is assembled into the interior of the fixed cylinder 1, if the liner 5 is directly installed inside, it is necessary to manually correct the position, and since the internal space of the fixed cylinder 1 is limited, it is inconvenient to operate. However, by utilizing the operating method of this embodiment, the operating space is large, the liner 5 is placed on the transfer gear ring 13 outside, and then the transfer gear ring 13 is used for transfer, thereby achieving one-step positioning, no correction is required, and the efficiency is high.

[0029] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
