Technical Field
[0001] The utility model relates to the technical field of pulp processing equipment, in particular to a pulping machine used for pulp molding production. Background Art
[0002] Pulp mill for pulp molding production plays a vital role in the pulp molding production process. It is mainly used to break down waste paper, pulp board and other raw materials into fibrous pulp, providing qualified pulp for subsequent forming, pressing and shaping processes.
[0003] During the use of traditional pulpers, debris will fly out from the feed port and accumulate, which will pose a challenge to the sanitary environment of pulp production in the long run, and workers are often required to clean it. However, since pulpers are large in size and are generally integrally formed, it is more troublesome to clean the inside of the pulper, especially the top of the inside.
[0004] Therefore, it is necessary to design a closed self-cleaning pulper for pulp molding production. Utility Model Content
[0005] In order to overcome the disadvantage that the traditional pulper often needs to be cleaned during use, but the pulper is large in size and generally formed in one piece, so it is troublesome to clean the inside of the pulper, especially the top of the inside, the technical problem of the utility model is to provide a pulper for pulp molding production. The technical implementation scheme of the utility model is: a pulper for pulp molding production, including: a cylinder and a turntable, a turntable is rotatably provided in the middle of the bottom of the cylinder; a discharge port, a discharge port is opened on the outside of the turntable under the cylinder; a rotor, a rotor is fixedly provided on the upper part of the turntable in the cylinder, and a blade is spirally provided on the rotor; a top cover, a top cover is provided on the top of the cylinder, and the top cover is like a cone; a water inlet, a water inlet is opened in the middle of the top of the top cover; a rotating cylinder, a rotating cylinder is rotatably provided inside the water inlet, and the bottom of the rotating cylinder extends into the cylinder; a fan blade, a fan blade is fixedly provided on the upper side of the rotating cylinder; a nozzle, nozzles are evenly opened on both sides of the arc above the rotating cylinder.
[0006] Optionally, it also includes: a cover, a fan-shaped feed port is opened on the conical side of the top cover, and a cover is rotatably provided at the feed hole on the conical side of the top cover; a convex tooth, a convex tooth is provided on the cover with the rotatable connection between the cover and the top cover as the center of the circle; a water baffle, a water baffle is slidably provided above the feed hole on the conical side of the top cover; a rack, a rack is fixedly provided on the water baffle close to one side of the cover; and an anti-drop block, an anti-drop block is fixedly provided above the rack.
[0007] Optionally, it also includes: a handle, and a handle is fixedly provided above the cover.
[0008] Optionally, it also includes: a support rod, which is arranged between a groove opened at the lower left side of the top cover near the feed inlet and a groove opened at the lower left side of the bottom of the lid.
[0009] Optionally, it further comprises: an anti-rotation block, and the top cover and the cylinder body are each fixedly provided with an anti-rotation block at the connection between the top cover and the cylinder body.
[0010] The utility model has the following advantages: 1. In the utility model, water flowing through the fan blades will cause the fan blades to have a tendency to rotate. Since the rotating cylinder fixedly connected to the fan blades is rotatably connected to the water inlet, the fan blades further drive the rotating cylinder to rotate. When the water flow continues to flow forward from the nozzle, it will be ejected due to the larger internal pressure of the water flow. As the rotating cylinder rotates, the water flow injection direction rotates accordingly, so that it can be sprayed to every place in the pulper for cleaning.
[0011] 2. The cover is provided with convex teeth with the rotatable connection between the cover and the top cover as the center of the circle, and the convex teeth cooperate with the teeth of the rack. When the cover is turned over, the water baffle fixedly matched with the rack slides accordingly, the cover is turned up, and the water baffle slides down to prevent water from spraying out of the pulper. When the cover is closed downward, the water baffle rises and will not prevent the spray of water from cleaning the inside of the pulper. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0016] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0017] Example 1
[0018] like Figures 1 to 3 As shown, the utility model provides a pulping machine for pulp molding production, which specifically includes: a cylinder 1, a turntable 2, a discharge port 3, a rotor 4, a top cover 5, a rotating cylinder 7, a fan blade 8 and a nozzle 9;
[0019] A rotating disc 2 is rotatably provided in the middle of the bottom of the cylinder 1, a discharge port 3 is provided on the outer side of the rotating disc 2 under the cylinder 1, a rotor 4 is fixedly provided on the rotating disc 2 in the inner part of the cylinder 1, and a blade is spirally provided on the rotor 4. A top cover 5 is provided above the cylinder 1, and the top cover 5 is cone-shaped, and a water inlet 6 is provided in the middle of the top of the top cover 5 for crushing the pulp;
[0020] Among them, the rotating cylinder 7 is rotatably arranged on the inner side of the water inlet 6, and the lower part of the rotating cylinder 7 extends into the cylinder body 1. The upper side of the rotating cylinder 7 is fixedly provided with fan blades 8, and nozzles 9 are evenly opened on both sides of the arc above the rotating cylinder 7, which are used to spray water stably on the inner wall of the cylinder body 1.
[0021] In the present invention, before use, ensure that the discharge port 3 is in a closed state. A large amount of pulp raw materials can be placed in the cylinder 1 to meet the production needs of large-scale pulp molding. The external motor power is transmitted to the turntable 2 through the pulley group to make the turntable 2 rotate. The rotation of the turntable 2 drives the rotor 4 in the cylinder 1 to rotate. The rotor 4 is spirally provided with blades to stir and crush the pulp raw materials. After running for a certain period of time and the pulp crushing degree meets the production needs, the motor rotation can be stopped. The turntable 2 loses its power source, the rotor 4 loses its power source, the stirring in the cylinder 1 stops, and the discharge port 3 can be opened. At the same time, in order to avoid the top cover 5 of the traditional pulper and the situation that the inside and around the pulper are very dirty, the top cover 5 of the utility model is set to a cone shape and is connected to the external water pump through the water inlet 6. The water flows in from the water inlet 6 and first passes through the rotating cylinder 7. As for the fan blade 8, water flows through the fan blade 8 and makes the fan blade 8 tend to rotate. Since the rotating cylinder 7 fixedly connected to the fan blade 8 is rotatably connected to the water inlet 6, the fan blade 8 drives the rotating cylinder 7 to rotate. When the water continues to flow forward from the nozzle 9, it will be ejected due to the larger internal pressure of the water flow. As the rotating cylinder 7 rotates, the water flow injection direction rotates accordingly. Since the inner side surface of the top cover 5 is a conical surface, the water flow will be ejected on the conical surface, and flow down along the conical surface and along the inner wall of the cylinder body 1. In this way, the utility model combines the traditional water injection method, and organically combines the production water and the cleaning water while realizing a relatively closed space to prevent pulp debris from floating out. There is no need for workers to clean the inside of the pulper later. Not only can the traditional water injection effect for pulp production be achieved, but also the internal space of the utility model can be cleaned to prevent pulp accumulation.
[0022] Example 2
[0023] like Figure 2 and Figure 3As shown, on the basis of Example 1, it specifically also includes: a cover 11, a fan-shaped feed port is opened on the conical side of the top cover 5, and the cover 11 is rotatably provided at the feed hole 10 on the conical side of the top cover 5; a convex tooth 12 is provided on the cover 11 with the rotatable connection between the cover 11 and the top cover 5 as the center of the circle; a water baffle 13, a water baffle 13 is slidably provided above the feed hole 10 on the conical side of the top cover 5; a rack 14, a rack 14 is fixedly provided on the side of the water baffle 13 close to the cover 11; an anti-fall block 15, an anti-fall block 15 is fixedly provided above the rack 14.
[0024] The staff puts waste paper and other raw materials into the pulper cylinder 1 through the feed hole 10, opens or closes the internal space of the pulper by flipping the cover 11, opens the cover 11 to put the materials in when feeding, and covers the cover 11 to prevent the materials from flying out when the pulper is working. In addition, when the staff flips up the cover 11, the convex teeth 12 rotate, driving the rack 14 to slide downward, and the water baffle 13 slides downward, which can prevent the water flow entering from the nozzle 9 at the lower end of the rotating hole from rushing into the feed port and spraying out. When the staff flips the cover 11 to close the cover 11, the convex teeth 12 rotate, driving the rack 14 to slide upward, and the water baffle 13 slides upward, so that the water baffle 13 will not prevent the spraying of water flow and affect the cleaning function in the pulper. In addition, there is an anti-fall block 15 at the upper end of the rack 14, which can prevent the convex teeth 12 from matching with the teeth of the rack 14 when the rack 14 drops to a certain height, and prevent the water baffle 13 from slipping off the top cover 5.
[0025] like Figure 3 As shown, based on the first embodiment, it further includes: a handle 16 , and a handle 16 is fixedly provided on the top of the cover 11 .
[0026] The handle 16 is disposed on the cover 11 , so that a worker can conveniently turn over the cover 11 through the handle 16 .
[0027] like Figure 1 As shown, based on Example 1, it specifically includes: a support rod 17, which is arranged between a groove opened on the lower left side of the top cover 5 near the feed inlet and a groove opened on the lower left side of the bottom of the cover 11.
[0028] The cover 11 can be kept in an open state by the support rod 17 to facilitate workers to put materials in.
[0029] like Figure 1 As shown, on the basis of Example 1, it specifically further includes: an anti-rotation block 18, and the top cover 5 and the cylinder body 1 are each fixedly provided with an anti-rotation block 18 at the connection between the top cover 5 and the cylinder body 1.
[0030] The anti-rotation block 18 can prevent the top cover 5 and the cylinder body 1 from rotating and displacing due to the pulper itself, thereby preventing the position of the feed inlet from changing.
[0031] Although the utility model is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications can be made to the utility model without departing from the principle and spirit of the utility model defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the utility model, but the scope of protection is limited by the content of the claims.
