To facilitate an understanding of the invention, the invention is described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present, unless the context clearly dictates otherwise.

It should be noted that when an element is referred to as being "secured" to another element, it may or may not be secured in a removable connection, unless specifically stated otherwise herein.

Referring to fig. 1 and 2, the horizontal stirring pulper includes a bucket body 1 for loading materials and a rotating shaft 2 installed in the bucket body 1. The rotating shaft 2 is driven to rotate by a motor 3 through a speed reducer. Seven groups of stirring assemblies are distributed along the axial direction of the rotating shaft 2. Each group of stirring components consists of four stirring rods 4 which are fixed on the rotating shaft 2 and are uniformly distributed along the circumferential direction of the rotating shaft. The arrows in fig. 2 indicate the rotation direction of the rotating shaft 2 and the stirring rod 4 rotated by the rotating shaft 2. The number of the stirring assemblies and the number of the stirring rods constituting each stirring assembly are not limited to the illustrated embodiment, and may be more or less depending on the size of the bucket body 1 and the length of the rotating shaft 2.

As shown in fig. 2, in a group of stirring assemblies closest to the left end of the rotating shaft, a blade 5 is fixed at the top end of each stirring rod 4a, and the helix angle of the blade 5 enables the blade to generate axial extrusion force towards the middle direction of the rotating shaft 2 on the material in the bucket body along with the rotation of the stirring rods 4 a. Similarly, in a group of stirring assemblies closest to the right end of the rotating shaft 2, a blade 6 is fixed at the top end of each stirring rod 4b, and the helix angle of the blade 6 enables the blade to generate axial extrusion force towards the middle direction of the rotating shaft 2 on the material in the bucket body along with the rotation of the stirring rods 4 b. In other stirring assemblies, two blades 7 and 8 with opposite spiral angles are fixed at the top end of each stirring rod 4 c. The helix angle of the blade 7 enables the blade to generate axial extrusion force towards the left end of the rotating shaft 2 on the materials in the bucket body along with the rotation of the stirring rod 4c, and the helix angle of the blade 8 enables the blade to generate axial extrusion force towards the right end of the rotating shaft 2 on the materials in the bucket body along with the rotation of the stirring rod 4 c.

In the preferred embodiment, the two blades 7, 8 with opposite pitch angles are fixed together two by two. Therefore, the axial forces exerted on the blades 7 and 8 which are fixed together in pairs and have opposite spiral angles can be counteracted, the acting force exerted on the stirring rod 4c in the axial direction of the rotating shaft 2 is reduced, and the stress condition of the stirring rod 4c and the rotating shaft 2 is improved.

Furthermore, wear plates 9 are paved on the surfaces of all the

blades

5, 6, 7 and 8, and the wear plates 9 are detachably connected with the blades, so that the replacement is convenient. The wear plate 9 may be made of rubber or the like. The attachment of the wear plate 9 to the paddle may be by a screw connection.

As a preferred embodiment, as shown in fig. 3, the inner wall of the bottom of the cross section of the bucket body 1 is circular arc-shaped when viewed from a direction perpendicular to the end surface of the rotating shaft 2, and the axis of the rotating shaft 2 is concentric with the arc center of the circular arc. Therefore, hard impurities such as stones and the like can be prevented from being clamped between the end part of the stirring rod and the bottom surface of the hopper body, and the blocking phenomenon which possibly occurs during stirring can be effectively prevented.

In a preferred embodiment, as shown in fig. 2, the stirring rods 4 of the same group of stirring assemblies are fixed on the same plate 10 to reinforce the connection between the stirring rods 4 and the rotating shaft 2. The fixing of the stirring rod 4 to the plate 10 can be, for example, welding.

As a preferred embodiment, referring to fig. 1, an overflow port 11 is provided in a side wall 1a of the bucket body 1. Before the material becomes thick liquid, can not spill over from overflow mouth 11 because the mobility of material is relatively poor, just can spill over from overflow mouth 11 automatically after the material becomes to have the thick liquids of mobility, just so can carry out the serialization thick liquid operation to the material, improved the production efficiency of change pulp grinder.

As a further improvement of the overflow port, as shown in fig. 1, the overflow port 11 is butted with a slurry discharge nozzle 12 extending laterally outward from the side wall 1a, and the slurry discharge nozzle 12 is fixed on the side wall 1a of the bucket body. Referring also to fig. 4, the inner wall of the lower side of the flow guiding nozzle 12 is upwardly arched to form a peak 12a, and the peak 12a is higher than the bottom edge 11a of the overflow opening 11 and lower than the top edge 11b of the overflow opening 11. The structural characteristics of the slurry outlet flow guide nozzle 12 can ensure that the slurry formed materials can smoothly flow out through the slurry outlet flow guide nozzle 12, and can prevent the slurry not formed yet and the materials with poor fluidity from flowing out, thereby not only realizing the continuous slurry formation of the materials, but also ensuring the slurry formation quality.

As a further improvement, as shown in fig. 1 and 4, an opening 12b is provided at the top of the slurry outlet nozzle 12. The opening 12b is convenient for sorting floating impurities such as branches from the flowing slurry.

It should be noted that if the function of continuous slurry formation is not required, the hopper body may not have an overflow port, and the slurry-formed material may be extracted from the hopper body by other means, such as a pump.

In order to facilitate the impurities precipitated in the hopper body 1 in the process of cleaning the slurry, as shown in fig. 4, the bottom of the hopper body 1 is connected with two slag discharge pipes 13 and 14, and the two slag discharge pipes are thick and thin. The finer deslagging pipe 13 is used for discharging finer sediment such as gravel, and the coarser deslagging pipe 14 is used for discharging larger sediment such as stones. The valve 15 of the thinner slag discharging pipe can adopt a ball valve. The valve 16 of the thicker slag discharging pipe can adopt an end plate made of metal, and the end plate is fixed at the end part of the slag discharging pipe 14 by screws.

In the preferred embodiment, as shown in fig. 1, the body 1 is mounted on top of a base 17, the base 17 is provided with a passageway 18 for workers to enter and exit, and the body 1 is located above the passageway 18. The passage 18 facilitates the worker to go under the bucket body 1 for deslagging. The base 17 may be a concrete structure or other structures.

It should be noted that the top of the bucket body 1 may be open or closed. If the top of the bucket body 1 is open as in the illustrated embodiment, the material to be pulped can be directly put in from the top of the bucket body 1. If the top of the bucket body 1 is closed, a material inlet needs to be additionally arranged on the side wall of the bucket body 1.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention.
