Description

Technical Field

[0001] This utility model relates to the field of pressing machinery and equipment, specifically to a wood pulp hydraulic press barrel and auxiliary assembly device. Background Technology

[0002] Wood pulp hydraulic presses mainly remove moisture from wood pulp through mechanical extrusion, thereby increasing the dry matter content of the pulp. There are two types of wood pulp hydraulic presses: screw presses and hydraulic presses.

[0003] When using a hydraulic press to press wood pulp, a wood pulp hydraulic press barrel is required. The material to be pressed is placed inside the wood pulp hydraulic press barrel, and the juice is squeezed out of the material by applying hydraulic pressure.

[0004] There are two types of pressing barrels: the mesh type and the key bar type. The mesh type pressing barrel has multiple perforations on its inner wall. Its structural strength is generally low, and it can withstand less pressure.

[0005] Key bar press barrels can withstand high pressure, but they are difficult to assemble and the gap width between the key bars is not easy to control.

[0006] For example, in the published patent CN219505501U, a discharge cylinder is formed by multiple key bars with trapezoidal cross-sections arranged in a ring. How to accurately arrange the key bars has become a problem that needs to be solved. Utility Model Content

[0007] The purpose of this utility model is to provide a wood pulp hydraulic press barrel and an auxiliary assembly device. The wood pulp hydraulic press barrel has positioning holes at both ends of the key bar. When assembling the wood pulp hydraulic press barrel, the first and second insert rods in the auxiliary assembly device are inserted into the positioning holes respectively, and then the flange ring is welded to the key bar to improve the assembly accuracy.

[0008] To achieve the above objectives, this utility model provides a wood pulp hydraulic press barrel, comprising a barrel body formed by multiple key strips circumferentially spaced together, and multiple flange rings welded and fixed to the barrel body. The outer thickness of each key strip is less than its inner thickness. A 1-2mm gap is formed between the inner sides of two adjacent key strips, and a 5-15mm gap is formed between the outer sides of two adjacent key strips. The inner end face of each key strip is a plane, and the outer end face is an arc surface that fits against the inner side of the flange ring. Two positioning holes are respectively arranged at both ends of each key strip along the radial direction of the flange ring.

[0009] Preferably, two baffles are symmetrically arranged on the left and right edges of the outer side of the key bar. Each baffle includes a first arc-shaped strip that bends outward and is connected to the key bar, and a second arc-shaped strip that bends inward and is connected to the first arc-shaped strip. The connection between the first arc-shaped strip and the second arc-shaped strip is tangential, and the first arc-shaped strip forms an angle of 10-20° with the side of the key bar.

[0010] Preferably, the side of the key bar includes a vertical surface that is perpendicularly connected to the plane, and an inclined surface disposed between the vertical surface and the arc surface, wherein the distance between the inclined surfaces on both sides gradually decreases from the inside to the outside.

[0011] Preferably, the width of the vertical plane is 1-3 mm.

[0012] This utility model also provides an auxiliary assembly device for assembling a wood pulp hydraulic press barrel, including an upper positioning seat and a lower positioning seat; a positioning rod is fixedly connected to the center of the lower positioning seat, and a positioning hole for inserting the positioning rod is provided at the center of the upper positioning seat; a plurality of first and second insert rods for inserting into the corresponding positioning holes are respectively provided on the upper and lower positioning seats; the end of the positioning rod is provided with an external thread, and a nut is sleeved on the external thread, and a sleeve for pressing on the upper positioning seat is fixedly connected to the inner end of the nut.

[0013] Preferably, the upper positioning seat includes an upper positioning ring and a plurality of upper spokes fixed within the upper positioning ring, and the positioning hole is disposed at the junction of the plurality of upper spokes; the lower positioning seat includes a lower positioning ring and a plurality of lower spokes fixed within the lower positioning ring, the positioning rod is fixed at the junction of the plurality of lower spokes, and the lower spokes are further provided with a plurality of mounting and fixing holes.

[0014] Preferably, the main body of the positioning rod is a regular hexagonal prism, the positioning hole is a regular hexagonal hole, the side of the regular hexagonal prism is provided with anti-foolproof ribs, and the side of the regular hexagonal hole is provided with anti-foolproof grooves.

[0015] According to the above technical solution, this utility model provides a wood pulp hydraulic press barrel, including a barrel body formed by multiple key strips circumferentially spaced together, and multiple flange rings welded and fixed to the barrel body. The outer thickness of the key strip is less than the inner thickness. A 1-2mm gap is formed between the inner sides of two adjacent key strips, and a 5-15mm gap is formed between the outer sides of two adjacent key strips. The inner end face of the key strip is a plane, and the outer end face is an arc surface that fits into the inner side of the flange ring.

Finally, the flanges are welded, increasing the accuracy of the key strip positions during the welding process. This avoids the problem of inconsistent gap widths and poor oil extraction caused by large deviations in the accuracy of key strip positioning.

Detailed Implementation

[0031] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0032] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0033] See Figure 1-9 The wood pulp hydraulic press shown includes a barrel body 1 formed by multiple key strips 16 circumferentially spaced together, and multiple flange rings 2 welded and fixed to the outside of the barrel body 1. The outer thickness of the key strips 16 is less than the inner thickness. A 1-2 mm gap 17 is formed between the inner sides of two adjacent key strips 16, and a 5-15 mm gap 18 is formed between the outer sides of two adjacent key strips 16. The inner end face of the key strip 16 is a plane 22, and the outer end face is an arc surface 23 that fits the inner side of the flange ring 2. Two positioning holes 21 are respectively arranged at both ends of the key strip 16 along the radial direction of the flange ring 2.

[0034] Through the implementation of the above technical solution, the wood pulp hydraulic press tank is formed by multiple key strips 16 surrounding and fixed by multiple flange rings 2 on the outside. By setting a gap 17 of 1-2mm between the inner sides of two adjacent key strips 16 and a gap 18 of 5-15mm between the outer sides of two adjacent key strips 16, a relatively open structure on the outside is formed, which increases the oil output effect. By setting the outer end face of the key strip 16 as an arc surface 23 that fits against the inner side of the flange ring 2, the connection tightness between the flange ring 2 and the key strip 16 is improved, and the structural strength is increased. In addition, two positioning holes 21 arranged radially are provided at both ends of the key strip 16 to facilitate the positioning of the key strip 16.

[0035] In this embodiment, two baffles are symmetrically arranged on the left and right edges of the outer side of the key strip 16. Each baffle includes a first outwardly curved arc-shaped strip 19 connected to the key strip 16, and a second inwardly curved arc-shaped strip 20 connected to the first arc-shaped strip 19. The connection between the first arc-shaped strip 19 and the second arc-shaped strip 20 is tangential, and an angle of 10-20° is formed between the first arc-shaped strip 19 and the side of the key strip 16. This arrangement prevents oil from leaking out of the gap 17 from being stopped by the two baffles on the left and right sides, thus preventing a large amount of oil from overflowing onto the flange plate through both sides of the key strip 16.

[0036] In this embodiment, to further provide a main structure for the key bar 16, the side of the key bar 16 includes a vertical surface 24 perpendicularly connected to the plane 22, and an inclined surface 25 disposed between the vertical surface 24 and the arc surface 23. The distance between the inclined surfaces 25 on both sides gradually decreases from the inside to the outside. This arrangement enhances the structural strength of the key bar 16 on both sides of the gap 17, making it less prone to deformation under pressure.

[0037] In this embodiment, the width of the vertical surface 24 is 1-3 mm. This setting prevents the vertical surface 24 from being too large, which would affect the oil dispensing effect. Setting it to 1-3 mm, while meeting the oil dispensing requirements, increases the structural strength at the gap 17, preventing deformation.

[0038] This utility model also provides an auxiliary assembly device for assisted assembly of wood pulp hydraulic press barrels, including an upper positioning seat 3 and a lower positioning seat 9; a positioning rod 12 is fixedly connected to the center of the lower positioning seat 9, and a positioning hole 6 is provided at the center of the upper positioning seat 3, which can insert the positioning rod 12; a plurality of first insert rods 14 and second insert rods 4 are respectively provided on the upper positioning seat 3 and the lower positioning seat 9, which can be inserted into the corresponding positioning insertion holes 21; the end of the positioning rod 12 is provided with an external thread 15, and a nut 7 is sleeved on the external thread 15, and a sleeve 8 that can press against the upper positioning seat 3 is fixedly connected to the inner end of the nut 7.

[0039] By implementing the above technical solution, the two positioning holes 21 at each end of the key bar 16 are inserted into the first insertion rod 14 and the second insertion rod 4 at each end. Then, the nut 7 is tightened, accurately positioning the multiple key bars 16. Finally, the flange ring 2 is welded, increasing the accuracy of the key bar 16's position during the welding process of the wood pulp hydraulic press. This avoids the problem of inconsistent gap widths 17 caused by large deviations in the accuracy of the key bar 16's position, resulting in poor oil extraction.

[0040] In this embodiment, to further provide an upper positioning seat 3 and a lower positioning seat 9, the upper positioning seat 3 includes an upper positioning ring and a plurality of upper spokes 10 fixedly connected within the upper positioning ring, and the positioning hole 6 is disposed at the junction of the plurality of upper spokes 10; the lower positioning seat 9 includes a lower positioning ring and a plurality of lower spokes 5 fixedly connected within the lower positioning ring, the positioning rod 12 is fixedly connected at the junction of the plurality of lower spokes 5, and the lower spokes 5 are also provided with a plurality of mounting and fixing holes 11.

[0041] In this embodiment, the main body of the positioning rod 12 is a regular hexagonal prism, the positioning hole 6 is a regular hexagonal hole, the side of the regular hexagonal prism is provided with a foolproof rib 13, and the side of the regular hexagonal hole is provided with a foolproof groove. With this arrangement, the regular hexagonal prism and the regular hexagonal hole are inserted into each other, and the foolproof rib 13 and the foolproof groove are inserted into each other, facilitating the alignment of the upper positioning seat 3 and the lower positioning seat 9 during assembly.

[0043] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
