Description

Silk screen pressing device

Technical Field

The utility model relates to a filler equipment field, concretely relates to silk screen closing device.

Background

The filling equipment occupies an important position in the chemical industry, and almost all chemical processes use the filling equipment. When using the filler equipment, when filling, all can lay one deck or several layers of mesh less than the silk screen of filler on the filler strutting arrangement usually, be used for preventing the filler unloading, make the material play the effect that the equipartition distributes after passing through the filler section simultaneously. However, in practice, since the screen is made in rolls, it is difficult to ensure that the screen does not curl when laid, and uneven or folded screen laying often occurs. In addition, the attachment of the silk screen and the inner wall of the shell is not covered, so that a non-silk-screen area is easy to appear, the phenomena of filler falling, uneven medium distribution and the like are caused when the equipment is used, and the service performance of the equipment is influenced. Therefore, need a closing device can overcome the silk screen and curl easily, lay not smooth, uneven problem, make the silk screen can be laminated with the barrel inner wall tightly simultaneously, make the silk screen can evenly lay the whole cross-section of equipment, the performance of equipment is guaranteed to the non-blind area.

Disclosure of Invention

The utility model discloses a solve the silk screen that current filler equipment laid and curl easily, lay unevenness, inequality, the silk screen does not hide with the laminating of shells inner wall, the technical problem in no silk screen district appears easily, provides a silk screen closing device.

For solving the technical problem, the utility model discloses the technical scheme who adopts does: a silk screen pressing device comprises a support ring and a pre-tightening ring, wherein the support ring and the pre-tightening ring are both non-closed broken rings; two end parts of the opening of the pre-tightening ring are fixedly connected with a connecting plate respectively, one connecting plate is provided with a hole, a nut is welded at the hole, the other connecting plate is provided with a lantern ring, the nut is screwed with a pre-tightening bolt, and the end part of the pre-tightening bolt is inserted into the lantern ring; the diameter of the lantern ring is slightly larger than that of the pre-tightening bolt; the support ring and the pre-tightening ring can generate elastic deformation under the action of external force, and the outer diameter of the support ring and the pre-tightening ring is larger than or equal to the inner diameter of the shell required to lay the silk screen when the support ring and the pre-tightening ring are in a natural state without the action of external force.

The working principle and the process are as follows: when the device is used, a pre-cut silk screen is laid flat and aligned, the support ring is pressed on the silk screen, the support ring and the silk screen are pushed into the device shell, the silk screen is adjusted to enable the middle silk screen of the support ring to be flat and uniform, then the silk screen outside the support ring is turned inwards to wrap the support ring, then the pre-tightening ring is clamped in the support ring, the edge of the silk screen is pressed, and the pre-tightening bolt is tightened to enable the pre-tightening ring and the support ring to clamp the silk screen. The support ring and the pre-tightening ring are both non-closed broken rings, the diameter of the support ring can be enlarged when the pre-tightening bolt is screwed to enlarge the diameter of the pre-tightening ring, the silk screen between the pre-tightening ring and the support ring is compressed, the silk screen between the support ring and the inner wall of the shell is also compressed, and meanwhile, the support ring and the pre-tightening ring clamp the silk screen to expand outwards, so that the silk screen is laid more smoothly and uniformly.

Compared with the prior art the utility model discloses following beneficial effect has:

the utility model has reasonable and simple structure design and low cost; the screen mesh is fixed and leveled by additionally arranging the support ring and the pre-tightening ring, the pre-tightening bolt is adjusted to tightly press the screen mesh, no gap is formed between the pre-tightening bolt and the inner wall of the shell, and a laying blind area is avoided; the problems of unevenness, untightening and blind areas in the conventional silk screen laying are solved.

Fig. 2 is a view taken along direction a of fig. 1, i.e., a partial plan view.

The figures are labeled as follows:

1-support ring, 2-pre-tightening ring, 3-wire mesh, 4-pre-tightening bolt, 5-connecting plate, 6-rib plate and 7-lantern ring.

Detailed Description

The present invention will be further described with reference to the following specific examples.

Example 1

As shown in fig. 1 and 2, a silk screen compressing device comprises a support ring 1 and a pre-tightening ring 2, wherein the support ring 1 and the pre-tightening ring 2 are both open and closed rings; two end parts of the opening of the pre-tightening ring 2 are fixedly connected with a connecting plate 5 respectively, one connecting plate 5 is provided with a hole, a nut is welded at the hole, the other connecting plate 5 is welded with a lantern ring 7, the nut is screwed with a pre-tightening bolt 4, and the end part of the pre-tightening bolt 4 is inserted into the lantern ring 7; the diameter of the lantern ring 7 is slightly larger than that of the pre-tightening bolt; the connecting plate 5 is provided with a lantern ring 7 which can fix the pre-tightening direction of the pre-tightening bolt 4; the stability of the device is improved. Support ring 1 and pretension ring 2 receive external force effect can produce elastic deformation, and support ring 1 and pretension ring 2 do not have external force effect external diameter more than or equal to the internal diameter of the casing of the silk screen that needs to lay when being in natural state. The lantern ring 7 is not provided with threads, only the pre-tightening bolt 4 is required to be sleeved, when the pre-tightening bolt 4 is screwed towards the direction of the lantern ring 7, the end part of the pre-tightening bolt 4 props against the lantern ring 7, and the connecting plate 5 provided with the lantern ring 7 is propped towards one side far away from the other connecting plate 5, so that the diameter of the pre-tightening ring 2 is enlarged.

During the use, with the silk screen that will cut in advance the flattening align, then press support ring 1 on silk screen 3, push away support ring 1 to the equipment casing together with silk screen 3, adjust silk screen 3, make support ring 1 middle silk screen 2 level, even, then wrap support ring 1 with support ring 1 outside silk screen turn-ups inwards, then block pretension ring 2 in support ring 1, push down the edge of silk screen 3, screw up pretension bolt 4, make pretension ring and support ring press from both sides tight silk screen. The support ring 1 and the pre-tightening ring 2 are both non-closed broken rings, the diameter of the support ring 1 can be enlarged when the pre-tightening bolt 4 is screwed to enlarge the diameter of the pre-tightening ring 2, the silk screen 3 between the pre-tightening ring 2 and the support ring 1 is compressed, meanwhile, the silk screen 3 between the support ring 1 and the inner wall of the shell is also compressed, and meanwhile, the support ring 1 and the pre-tightening ring 2 clamp the silk screen 3 to be expanded outwards, so that the silk screen is laid more smoothly and uniformly. The whole device is easy to install and disassemble, the replacement and installation efficiency of the silk screen 3 can be effectively improved, the installation quality is improved, and the service performance of equipment is ensured.

Furthermore, rib plates 6 are welded on the end parts of the connecting plates 5 and the pre-tightening ring 2 together. The rib plate 6 is arranged behind the connecting plate 5 at the break of the pre-tightening ring 2, so that the rigidity of the connecting plate 5 during bolt tightening can be improved.
