Description

Technical Field

[0001] The utility model relates to the technical field of jellyfish heads, in particular to a non-woven fabric jellyfish head. Background Art

[0002] The spunlace head is a key component in the production process of spunlace non-woven fabrics. It is mainly installed on the spunlace machine. When the fiber web enters the spunlace machine, the spunlace head inside the machine will spray out extremely fine and high-pressure water jets. These water jets hit the fiber web, causing the fibers to entangle with each other, thus forming a non-woven fabric. In order to prevent the impurities in the water needle from contaminating the non-woven fabric and to ensure the stability of the pressure of the water needle jet, a filter net for filtering the water body is provided in the spunlace head. After long-term use, the filter holes on the filter net will be clogged due to the accumulated impurities, thus requiring periodic maintenance and cleaning. However, the current filter net needs to be removed from the spunlace head when cleaning, and the cylindrical shape also makes it difficult to clean the interior, causing inconvenience in maintenance.

[0003] In view of this, a design or technical improvement is now proposed to solve the above problems.

[0004] The above contents are only used to assist in understanding the technical solution of the present utility model, and do not constitute an admission that the above contents are the closest prior art. Utility Model Content

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] like Figure 1-7 The non-woven fabric water jet head shown in the figure comprises a box body 1 and a water receiving pipe head 11 arranged on the box body 1 and connected to the box body 1. The box body 1 is provided with an inverted "V"-shaped filter screen 2 with both ends abutting against the inner wall, so that it is convenient to rinse and clean it with water. The filter screen 2 divides the box body 1 into two parts, a filter compartment 21 and a jet compartment 22, and the water receiving pipe head 11 is connected to the filter compartment 21; the box body 1 is provided with a water diversion box 23 connected to the jet compartment 22 outside, and the water diversion box 23 is provided with a connecting pipe 24 connected to it. The connecting pipe 24 and the water receiving pipe head 11 are connected with a reversing valve 25. The reversing valve 25 is provided with an external pipe 26 connected to high-pressure water. In normal use, In this state, the high-pressure water introduced by the external pipe 26 flows into the filter chamber 21 through the water inlet pipe head 11, and then passes through the filter screen 2 downward for filtration and then enters the jet chamber 22, and then jets downward to form a water needle. When the filter screen 2 needs to be cleaned, the high-pressure water is reversed by the reversing valve 25, so that it flows into the water inlet box 23 through the connecting pipe 24, and then enters the jet chamber 22. The jet chamber 22 diffuses upward through the filter screen 2 under the action of high pressure, and the impurities blocked on the filter screen 2 are flushed out in the reverse direction for cleaning. When the cleaning is completed, the reversing valve 25 is reversed, and then the water flow is passed in the forward direction to clean the inside of the jet chamber 22, and finally the cleaning work is completed.

[0025] In one embodiment, a plurality of groups of flow bridge tubes 3 having the same shape as the filter screen 2 and being hollow inside are evenly distributed in the jet chamber 22, and a plurality of groups of water jet needles 31 evenly distributed are connected to the flow bridge tubes 3. The ends of the flow bridge tubes 3 are connected to the water diversion box 23 via side water pipes 32 which are penetrated and arranged on the side walls of the box body 1. After the high-pressure water is introduced into the water diversion box 23, it flows to the inside of the flow bridge tubes 3 and diffuses. The water jet needles 31 are used to enhance the water pressure to jet upward, thereby strengthening the impact force of the water flow on the filter screen 2 and better clearing the filter holes.

[0026] In one embodiment, a sliding block 4 is provided at one end of the flow bridge pipe 3 away from the side water pipe 32, and limiting slide grooves 41 are provided on both side walls of the box body 1 for the sliding block 4 and the side water pipe 32 to slide horizontally. A water sealing plate 42 is provided between multiple groups of side water pipes 32 and multiple groups of sliding blocks 4, which is sealed and slid on the outer wall of the box body 1 to enclose the limiting slide groove 41. In order to ensure the comprehensive flushing of the filter screen 2 by the flow bridge pipe 3, the sliding block 4 and the side water pipe 32 can slide in the limiting slide groove 41, thereby driving the flow bridge pipe 3 to slide, so that the flow bridge pipe 3 can flush the filter screen 2 through back and forth movement, and then the setting of the water sealing plate 42 prevents water from flowing into the jet chamber 22 from the gap formed between the sliding block 4, the side water pipe 32 and the limiting slide groove 41, so as to maintain the high stability of the water pressure inside the flow bridge pipe 3 and the impact force of the water jet from the water jet needle 31 to the lower surface of the filter screen 2.

[0027] In one embodiment, an outer sealing box 5 for sealing the sliding block 4 is further provided on the outside of the box body 1, and a reciprocating threaded screw 51 is rotatably connected inside the outer sealing box 5, and a driving electric box 52 for driving the reciprocating threaded screw 51 to rotate is provided at one end of the reciprocating threaded screw 51, and the sliding blocks 4 are connected by connecting blocks 53, and the connecting blocks 53 at both ends are provided with screw sleeves 54 that reciprocate on the reciprocating threaded screw 51. The reciprocating threaded screw 51 is driven to rotate by the driving electric box 52, thereby driving the flow bridge pipe 3 to reciprocate, thereby automatically realizing the reciprocating flushing work of the flow bridge pipe 3 on the filter screen 2.

[0028] In one embodiment, drainage grooves 6 connected to the filter bin 21 are further provided on both sides of the box body 1, and a flow pipe 61 for drainage is provided on the drainage groove 6, and a detachable cap 62 is provided on the flow pipe 61. When cleaning the filter screen 2, it is necessary to open the cap 62. After backwashing the filter screen 2, the impurity-mixed water flow at its upper end flows to both sides through the inclined surface of the upper surface of the filter screen 2, and then enters the drainage groove 6 and discharges the impurities through the flow pipe 61. The flow pipe 61 can be connected to an external water pipe for directional drainage, which is convenient for subsequent processing.

[0029] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
