Description

Technical Field

[0001] The present invention belongs to the technical field of auxiliary facilities for the production of down products, and particularly relates to a floor suction structure for a down filling place of down products. Background Art

[0002] As is known in the industry, in order to make the down have good dispersibility, that is, to avoid the occurrence of agglomeration (also called "reunion"), it is usually necessary to add a reasonable amount of additives such as talcum powder to the down. Therefore, in the process of filling the weighed down by a weighing mechanism such as a weighing box (also called a "weighing hopper") into a prefabricated down tube by the filling head of a filling machine by means of air flow, that is, gas pressure, the above-mentioned additives such as talcum powder, the fine fiber in the form of fluff dust generated by the down itself, etc. will diffuse from the holes, that is, the cloth holes, of the tube usually made of woven cloth to the outside. The impurities diffused to the outside will fill the filling workplace in the form of fog. When the on-line filling personnel inhale the polluted air for a long time, it will undoubtedly affect their physical health and even cause pneumoconiosis. Therefore, as a down product manufacturer, avoiding the pollution of the air in the filling place not only helps to protect the physical health of production workers, but also helps to reflect safety, because when the fluff dust concentration is high to a saturated level, once static electricity is generated, accidents such as dust explosion will be caused.

[0003] At present, the measures to reduce the fluff dust in the filling place are generally to equip a dust suction hood for the filling workbench accompanying the filling machine. For this, reference can be made to the following patents not limited to examples: CN211688247U (a filling operation table with structural improvement), CN103613061A (the filling workbench structure of a filling machine), and CN219838204U (a filling workbench), etc. However, due to the relatively limited coverage range and suction force of the dust suction hood located above the workbench, it is impossible to ideally suck out the fluff dust and the like in the covered area. There are often different degrees, even relatively serious, floating situations of fluff dust in the air at the filling site, and the floating fluff dust will accumulate on the floor after settling. Since the work of removing the fluff dust accumulated on the floor is very troublesome and will cause secondary dust pollution, it has puzzled the industry quite a lot. However, if the floor cannot be kept clean and the fluff dust is allowed to accumulate, it will pollute the floor environment, and even bacteria such as mold will grow when the temperature and humidity are appropriate.

[0004] In view of the above situation, it is of positive significance to explore a facility that can effectively remove the fluff dust and impurities accumulated on the floor of the filling place caused by filling and settled. The technical solution to be introduced below was generated under this background. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to more clearly understand the technical essence and beneficial effects of the present invention, the applicant will make a detailed description below in the form of embodiments. However, the descriptions of the embodiments are not limitations on the technical solution of the present invention. Any equivalent transformation that is merely formal rather than substantial based on the concept of the present invention should be regarded as falling within the scope of the technical solution of the present invention.

[0019] In the following descriptions, all concepts related to directions or orientations such as up, down, left, right, front, and back are based on the position state of the figures being described. Therefore, they cannot be understood as special limitations on the technical solution provided by the present invention.

[0020] Please refer to Figure 1, shows a container carrying frame 1, which is supported on the base floor 5 in a state where a cavity 6 is maintained between it and the base floor 5 of a down filling place such as a down filling room or a down filling house. And the container carrying frame 1 is composed of frame units 11 arranged in an array, with a plurality of horizontal rows arranged side by side in the horizontal direction and a plurality of vertical rows arranged side by side in the vertical direction. Each two adjacent frame units 11 are both independent and connected to each other; shows an upper-open lint and dust converging container 2, the number of which is equal to the number of the aforementioned frame units 11 and is supported on the frame units 11. On the side wall of the lint and dust converging container 2 and at the lower part, there is provided a suction pipe line connection hole 22 for sucking out the lint and dust converging in the lint and dust converging container cavity 21 during the dust suction process; shows a hollow cover plate 3, the number of which is equal to the number of the aforementioned lint and dust converging containers 2, and is matched with the upper opening of the lint and dust converging container 2 and communicates with the aforementioned lint and dust converging container cavity 21. Among them, the aforementioned hollow cover plate 3 is configured as a hollow paving and stepping layer relative to the aforementioned base floor 5; shows a dust suction mechanism 4 for sucking out lint and dust, which is arranged in the aforementioned cavity 6 and is connected to the aforementioned suction pipe line connection hole 22.

[0021] The concept of the above-mentioned base floor 5 is the original floor of the down filling workshop or the down filling house. According to professional common sense, for a down product manufacturer of a certain scale, a required number of down filling machines are equipped in a down filling workshop or a down filling house according to the area size. The fact that each two adjacent frame units 11 are both independent and connected to each other means that each frame unit 11 is the same in function and independent in form, while relative to the adjacent frame units 11, they are connected to each other at the upper part to form a spliced modular effect. The above-mentioned hollow paving and stepping layer is essentially a hollow cover plate layer, because the container carrying frame 1 composed of frame units 11 has good strength, and when the staff steps on the frame units 11, it is sufficient to bear the weight of the human body.

[0022] Please refer to Figure 1, the foregoing frame unit 11 includes front and rear crossbeams 111, 112, left and right crossbeams 113, 114, front left and right crossbeam support feet 115, 116, rear left crossbeam support foot 117, and rear right crossbeam support foot 118. The front crossbeam 111 is fixed between the tops of the front left and right crossbeam support feet 115, 116 by front crossbeam fixing bolts 1111. The rear crossbeam 112 is fixed between the tops of the rear left and right crossbeam support feet 117, 118 by rear crossbeam fixing bolts 1121. The left crossbeam 113 is fixed between the tops of the front left crossbeam support foot 115 and the rear left crossbeam support foot 117 by left crossbeam fixing bolts 1131. The right crossbeam 114 is fixed between the tops of the front right crossbeam support foot 116 and the rear right crossbeam support foot 118 by right crossbeam fixing bolts 1141. The bottoms of the front left and right crossbeam support feet 115, 116, rear left crossbeam support foot 117, and rear right crossbeam support foot 118 are fixed to the foregoing foundation floor 5, and the space between the tops and bottoms of the front left and right crossbeam support feet 115, 116, rear left crossbeam support foot 117, and rear right crossbeam support foot 118 constitutes the foregoing empty cavity 6. The foregoing fluff and dust collecting container 2 together with the foregoing hollow cover plate 3 is supported on the front and rear crossbeams 111, 112, left crossbeam 113, and right crossbeam 114 at a position corresponding to the crossbeam enclosing cavity 119a formed by the common enclosure of the foregoing front and rear crossbeams 111, 112, left crossbeam 113, and right crossbeam 114. The tops of the front left and right crossbeam support feet 115, 116, rear left crossbeam support foot 117, and rear right crossbeam support foot 118 of the foregoing adjacent frame units 11 are fixedly connected by support foot top common connection bolts 119b.

[0023] by Figure 2As shown, an extension plate is preferably fixed to the top and bottom of the above-mentioned front left and right cross beam supporting feet 115, 116, rear left cross beam supporting foot 117 and rear right cross beam supporting foot 118 by welding. Since their structures and fixing methods are the same and their functions are also consistent, the applicant takes the front left cross beam supporting foot 115 as an example for the following explanation: a rectangular top connecting extension plate 1151 is preferably welded to the position of the front left cross beam supporting foot 115 by welding, and a pair of two aforementioned supporting foot top common connecting bolts 119b are provided on the upper part of the top connecting extension plate 1151. The two supporting foot top common connecting bolts 119b are obviously used to fix to the left end of the rear cross beam 112 of another frame unit 11 and the front end of the right cross beam 114. A bottom connecting expansion plate 1152 which is also rectangular in shape and the same size as the aforementioned top connecting expansion plate 1151 is also preferably welded and fixed to the bottom of the front left crossbeam supporting foot 115 by means of welding, and the bottom connecting expansion plate 1152 is fixed to the embedded parts on the aforementioned foundation floor 5 by bolts at positions corresponding to the bolt holes preset on the bottom connecting expansion plate 1152. Such a structure can meet the aforementioned array arrangement requirements. In this embodiment, the specific size of the aforementioned crossbeam enclosure cavity 119a does not need to be particularly limited, for example, it can be a square with a side length of 50 cm, 60 cm, 70 cm, 80 cm or 100 cm, or it can be a rectangle of a reasonable size selected as needed. When the dust and debris collection container 2 is settled on the crossbeam enclosure cavity 119a and after the hollow cover plate 3 is matched with the upper open position of the dust and debris collection container 2, especially Figure 2 When the frame units 11 are arranged in the aforementioned array, the effect is like a stage for performances.

[0024] See you next time Figure 2 A dust and debris collection container supporting flange 23 is formed at the aforementioned upper opening of the aforementioned dust and debris collection container 2 and around the upper opening. The dust and debris collection container supporting flange 23 is supported on the upper surfaces of the aforementioned front and rear cross beams 111, 112, left cross beam 113 and right cross beam 114; the surrounding edge portions of the aforementioned hollow cover plate 3 facing downward are sealed with the inner wall of the upper opening of the aforementioned dust and debris collection container 2.

[0026] In this embodiment, although the shape of the dust inlet hole 31 shown on the hollow cover plate 3 is a long strip hole with arcs at both ends or an elliptical hole, it can also be a circular hole, a rectangular hole, a polygonal hole (such as a triangular or regular hexagonal hole) or other similar forms as long as it can meet the requirement of allowing the dust and debris on the surface of the hollow paving layer to smoothly enter the dust and debris gathering container cavity 21, then it is feasible.

[0027] Preferably, a sealing ring 34 is provided around the downward side of the aforementioned hollow cover plate 3 and on the outer side of the aforementioned sealing fitting stack edge 33. When the hollow cover plate 3 is covered with the aforementioned open portion of the aforementioned lint and dust collection container 2, the aforementioned sealing ring 34 is sealingly fitted with the aforementioned lint and dust collection container supporting flange edge 23.

[0028] Preferably, the aforementioned lint and dust collection container 2 is a side-hole quadrangular pyramid-shaped bucket with an open top and a closed bottom, that is, the shape of the lint and dust collection container 2 is an inverted quadrangular pyramid, and the diameter of the lint and dust collection container cavity 21 gradually decreases from top to bottom. The aforementioned lint and dust collection container 2 can be made of metal, or plastic or cloth.

[0029] See also Figure 3, the aforementioned dust suction mechanism 4 disposed in the aforementioned dust evacuation cavity 6 includes a dust suction pipe line connection hole connecting pipe elbow 41, a three-way pipe joint 42, a dust suction pipe line connection hole opening and closing control pipe 43, a control pipe opening and closing device 44, a two-way pipe joint 45, a dust suction branch pipe 46, a dust suction main pipe four-way joint 47, and a dust suction main pipe 48. One end of the dust suction pipe line connection hole connecting pipe elbow 41 is connected to the aforementioned dust suction pipe line connection hole 22 and communicates with the aforementioned fluff and dust accumulation container cavity 21, and the other end is connected to the three-way pipe joint first interface 421 of the three-way pipe joint 42 through an elbow transition connecting pipe 411. The three-way pipe joint second interface 422 of the three-way pipe joint 42 is connected to one end of the dust suction pipe line connection hole opening and closing control pipe 43 through a three-way pipe joint transition connecting pipe 4221. The three-way pipe joint third interface 423 of the three-way pipe joint 42 is connected to the adjacent one or another aforementioned fluff and dust accumulation container 2 pipeline, namely the corresponding elbow transition connecting pipe 411. The other end of the dust suction pipe line connection hole opening and closing control pipe 43 is connected to one end of the two-way pipe joint 45 through a two-way joint transition connecting pipe 451. The control pipe opening and closing device 44 is disposed on the dust suction pipe line connection hole opening and closing control pipe 43 and is electrically connected to an external electrical controller by a circuit.

The dust suction main pipe 48 is connected to a dust suction power device.

[0030] The applicant needs to explain that although only the pipeline connection between the dust suction mechanism 4 and one fluff and dust accumulation container cavity 21 is described above, it will not cause any confusion in understanding the pipeline connection between the dust suction mechanism 4 and all other fluff and dust accumulation container cavities 21, because it can be inferred by analogy. In addition, from Figure 3 the schematic diagram shows that the pipeline connecting every two adjacent fluff and dust accumulation containers 2 shares one control pipe opening and closing device 44.

[0034] According to the above description of the applicant, regardless of the area size of the down filling workshop or down filling room, as long as the frame unit 11 of reasonable specifications, that is, reasonable dimensions, is used as needed, a whole container bearing frame 1 can be formed in the array arrangement manner described above, and the corresponding number of fluff and dust converging containers 2 and hollow covers 3 are equipped. Then, the entire down filling workshop or down filling room can form a whole hollow paving and trampling layer.

[0035] The above-mentioned dust suction main pipe 48, the air outlet 481 of the dust suction main pipe are connected to the dust suction power device, for example, connected to the air inlet of the exhaust fan arranged in the dust suction box. Under the operation of the exhaust fan, the lint dust and impurities introduced into the dust suction main pipe 48 by the four-way joint 47 of the dust suction main pipe are sucked into the air inlet of the exhaust fan and then led out from the air outlet of the exhaust fan. In the above process, under the action of negative pressure, the sundries such as lint dust settling on the hollow-shaped paving and stepping layer pass through the dust inlet 31, the lint dust and impurity converging container cavity 21, the elbow connecting pipe 41 connected to the dust suction pipe connection hole 22, the elbow transition connecting pipe 411, the first interface 421 of the three-way joint of the three-way pipe joint 42, the second interface 422 of the three-way pipe joint, the transition connecting pipe 4221 of the three-way pipe joint, the pipe cavity 434 of the opening and closing control pipe 43 of the dust suction pipe connection hole (the pipe cavity closing valve piece 446 of the control pipe opening and closing device 44 is in the open state), the two-way joint transition connecting pipe 451, the two-way pipe joint 45, the dust suction branch pipe 46, the first interface 471 of the four-way joint of the dust suction main pipe four-way joint 47, the third interface 473 of the four-way joint of the dust suction main pipe four-way joint 47 and the fourth interface 474 of the four-way joint and enter the dust suction pipe 48 and are led out from the above-mentioned air outlet 481 of the dust suction main pipe.

[0036] In the above process, the lint dust and debris on the surface of the hollow-shaped paving and stepping layer, that is, on the surface of the hollow cover plate 43, are removed like fallen leaves swept by the autumn wind.

[0037] The application or activation time of the present invention can be determined as needed. Specifically, it can be sucked once at a reasonable interval while filling the fluff in the fluff filling place, or it can be sucked once after the end of a fluff filling shift, or it can be sucked once according to the lint dust condition. Furthermore, it can be sucked once every few days and the suction time each time can be as short as a few minutes, for example, as short as 2-4 minutes.

[0038] Subsequently, according to the lint dust accumulation area condition, the corresponding area control pipe opening and closing device 44 can be activated only by operating the electric controller, so that the above-mentioned pipe cavity opening and closing valve pieces 446 in other areas are in the closed state, so as to avoid blindness, reflect good flexibility and pertinence, and can also reasonably save energy such as reducing power consumption.

[0039] In summary, the technical solution provided by the present invention makes up for the deficiencies in the prior art, successfully completes the invention task, and truthfully realizes the technical effects described by the applicant in the above technical effect column.
