Description

Technical Field

[0001] The utility model belongs to the technical field of papermaking pulping equipment, in particular to a side cover for a pulp washer. Background Art

[0002] The pulp washer is a conventional equipment in the papermaking process, and the side cover of the existing pulp washer still adopts a sealing gasket set between the frame and the side cover, and a large number of bolts are tightened at the junction of the frame and the side cover to deform the sealing gasket, thereby eliminating the gap between the frame and the side cover, thereby avoiding the problem of overflow of washing liquid.

[0003] However, in actual use, it is found that the existing side cover has the following deficiencies during sealing installation:

[0004] 1) When installing the side cover, it is usually necessary to use a related lifting device to suspend the side cover to the specified position of the rack before further installation work can be carried out; due to the large size and weight of the side cover, it requires the cooperation of multiple workers to complete the installation work. This installation method is not only time-consuming and labor-intensive, but also has certain safety hazards.

[0005] 2) In order to ensure the sealing reliability of the gasket, a large number of bolts need to be closely distributed at the junction of the frame and the side cover. Although this setting can ensure the reliability of the connection, it significantly reduces the efficiency of equipment installation and disassembly, thereby increasing the time spent on equipment construction and subsequent maintenance.

[0006] 3) In order to facilitate the installation of the gasket, it is usually necessary to reserve a positioning hole at the designated position of the gasket so that the bolt can smoothly pass through the gasket for tightening. However, the setting of the positioning hole is easy to damage the integrity of the gasket. As time goes by, leakage will occur at the junction of the frame and the side cover. Utility Model Content

[0042] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0043] The most critical concept of the utility model is that the driving member drives the side cover body to move toward the inflatable seal, and then the expansion effect of the inflatable seal can quickly eliminate the gap between the inflatable seal and the side cover body, thereby realizing fully automatic installation and fully automatic sealing work, thereby significantly improving the installation efficiency and saving labor costs during installation.

[0044] Please refer to Figures 1 to 5The side cover for a pulp washer provided by the utility model comprises a frame 1, an inflatable seal 2, a side cover body 3, and a driving member 4 capable of driving the side cover body 3 to move toward the sealing end of the inflatable seal 2;

[0045] The inflatable seal 2 is arranged on the frame 1;

[0046] The side cover body 3 is hinged to the frame 1 through a driving member 4;

[0047] When the side cover body 3 abuts against the inflatable seal 2, the frame 1 and the side cover body 3 form a sealing structure.

[0048] From the above description, it can be seen that the beneficial effect of the utility model is that: a side cover for a pulp washer is provided, in which the driving member 4 drives the side cover body 3 to move toward the inflatable seal 2, and then the gap between the inflatable seal 2 and the side cover body 3 can be quickly eliminated through the expansion effect of the inflatable seal 2. Compared with the existing side covers for pulp washers, the utility model has fully automatic installation and fully automatic sealing functions, thereby significantly improving the sealing installation efficiency and saving labor costs during installation.

[0049] Furthermore, a sealing plate 31 is provided on the side cover body 3;

[0050] The driving member 4 can drive the sealing plate 31 to move toward the sealing end of the inflatable sealing member 2;

[0051] When the sealing plate 31 abuts against the inflatable seal 2, the frame 1 and the side cover body 3 form a sealing structure.

[0052] Furthermore, the inflatable seal 2 includes a limiting groove 21, an inflatable member 22 and an air source device;

[0053] The bottom of the limiting groove 21 is connected to the frame 1, and the notch of the limiting groove 21 is located on the rotation path of the sealing plate 31;

[0054] The inflatable member 22 is disposed in the limiting groove 21;

[0055] The air source device is communicated with the inflatable member 22 .

[0056] From the above description, it can be seen that the design specifically defines the sealing structure between the side cover body 3 and the inflatable seal 2. By setting the limiting groove 21, it can play a limiting role in the process of the inflatable part 22 expanding, so that the inflatable part 22 can only expand toward the opening of the limiting groove 21. Therefore, when the sealing plate 31 contacts the inflatable seal 2, the gap between the inflatable part 22 and the sealing plate 31 can be quickly eliminated, thereby achieving a rapid sealing effect.

[0057] Furthermore, the frame 1, the side cover body 3 and the driving member 4 are hinged to each other to form a guide rod mechanism.

[0058] From the above description, it can be seen that the design specifically defines the connection relationship and layout between the frame 1, the side cover body 3 and the driving member 4. The driving member 4 serves as the side cover body 3 and the power source. Since the three are hinged to each other, in the process of driving the side cover body 3 to rotate, the driving member 4 also rotates a certain angle accordingly, thereby avoiding the problem of interference among the three.

[0059] Furthermore, the side cover body 3 is also provided with a locking assembly 32;

[0060] The locking assembly 32 includes a locking head 321 and a driving device 322;

[0061] The driving device 322 is connected to the side cover body 3;

[0062] The movable end of the driving device 322 is connected to the lock head 321 , and the movable end of the driving device 322 is arranged toward the frame 1 .

[0063] Furthermore, a limit stopper is provided on the frame 1;

[0064] When the side cover body 3 abuts against the inflatable seal 2 , the limit stopper is arranged opposite to the lock head 321 .

[0065] Furthermore, the outer side surface of the lock head 321 is provided with a first inclined surface;

[0066] The limiting surface of the limiting stopper is provided with a second inclined surface which is parallel to the first inclined surface;

[0067] The first inclined surface extends from an end of the lock head 321 close to the driving device 322 to an end of the lock head 321 away from the driving device 322, and the end of the lock head 321 away from the driving device 322 is a small end;

[0068] When the side cover body 3 abuts against the inflatable seal 2, the first inclined surface and the second inclined surface abut against each other. Specifically, the side cover body 3 and the frame 1 can also achieve a locking effect by using a locking hole and a locking head 321 that cooperate with each other, that is, the frame 1 is also provided with a locking hole that matches the locking head 321; the locking hole is a blind hole; when the locking head 321 abuts against the bottom of the blind hole, the locking work of the side cover body 3 and the frame 1 can be quickly completed.

[0069] From the above description, it can be seen that the design can simplify the installation steps of the side cover body 3. When the driving member 4 drives the side cover body 3 to rotate a certain angle until it is against the inflatable seal 2, the driving device 322 can drive the lock head 321 to move quickly toward the limit block. Compared with the traditional bolt fastening, the installation time can be significantly reduced. The mutual extrusion of the first bevel and the second bevel can effectively eliminate the gap between the side cover body 3 and the frame 1, so as to improve the installation efficiency and tightness. At the same time, the rapid sealing function of the inflatable seal 2 is combined to achieve a rapid sealing installation effect.

[0070] From the above description, it can be seen that this design can limit the lock head 321, preventing the lock head 321 from being separated from the lock hole due to excessive movement of the lock head 321 by the driving device 322, thereby affecting the locking effect of the side cover and the sealing during the use of the device.

[0071] The side cover of the utility model for a pulp washer can assist papermaking work.

[0072] Please refer to Figures 1 to 5 , Embodiment 1 of the present utility model is:

[0073] A side cover for a pulp washer, comprising a frame 1, an inflatable seal 2, a side cover body 3, and a driving member 4 capable of driving the side cover body 3 to move toward the sealing end of the inflatable seal 2; the inflatable seal 2 is arranged on the frame 1; the side cover body 3 is hinged to the frame 1 through the driving member 4; a sealing plate 31 and a locking assembly 32 are provided on the side cover body 3; the driving member 4 can drive the sealing plate 31 to move toward the sealing end of the inflatable seal 2; when the sealing plate 31 abuts against the inflatable seal 2, the frame 1 and the side cover body 3 form a sealing structure; the frame 1, the side cover body 3 and the driving member 4 are hinged to each other to form a guide rod mechanism; the inflatable seal 2 comprises a limiting groove 21, an inflatable member 22 and an air source device (not shown in the figure); the groove bottom of the limiting groove 21 is connected to the frame 1, and the notch of the limiting groove 21 is located on the rotation path of the sealing plate 31; the inflatable member 22 is arranged at the limiting groove 21. The cam 322 is in the position groove 21; the air source device is connected with the inflatable member 22; the locking assembly 32 includes a lock head 321 and a driving device 322; the driving device 322 is connected with the side cover body 3; the movable end of the driving device 322 is connected with the lock head 321, and the movable end of the driving device 322 is arranged toward the frame 1; a limit stopper is also provided on the frame 1; when the side cover body 3 and the inflatable seal 2 are in contact, the limit stopper and the lock head 321 are arranged opposite to each other; the outer side surface of the lock head 321 is provided with a first inclined surface; the limiting surface of the limit stopper is provided with a second inclined surface parallel to the first inclined surface; the first inclined surface extends from one end of the lock head 321 close to the driving device 322 to one end of the lock head 321 away from the driving device 322, and the end of the lock head 321 away from the driving device 322 is a small head end; when the side cover body 3 and the inflatable seal 2 are in contact, the first inclined surface and the second inclined surface conflict.

[0074] The working principle of the utility model is as follows: when installing the side cover body 3, the side cover body 3 is driven to rotate in a directional manner by the driving member 4 until the sealing plate 31 on the side cover body 3 abuts against the inflatable seal 2, the locking assembly 32 is started, and the driving device 322 drives the lock head 321 to move toward the lock hole on the frame 1. When the lock head 321 abuts against the bottom of the lock hole, the lock head 321 is just engaged with the lock hole; finally, a large amount of gas is filled into the inflatable member 22 by the air source device, so that the gap between the inflatable seal 2 and the side cover body 3 can be quickly eliminated, thereby completing the overall sealing installation work.

[0075] When the side cover body 3 needs to be disassembled, the disassembly work can be completed by simply reversing the above process.

[0076] To sum up, the utility model provides a side cover for a pulp washer, in which a driving member drives the side cover body to move toward the inflatable seal, and then the gap between the inflatable seal and the side cover body can be quickly eliminated through the expansion effect of the inflatable seal.
