[0041] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the accompanying drawings required for use in the embodiments will be briefly introduced below. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention, and those of ordinary skill in the art can also obtain other drawings based on these drawings without creative efforts.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and specific implementation manners. The implementation manners cannot be elaborated one by one here, but the implementation manners of the present invention are not limited to the following implementation manners.

[0043] Combined with Figures 1-8As shown in the figure, the present invention provides a dust removal device for sheet processing, which includes a dust removal and separation device 1, a secondary separation device 2, a tertiary separation device 3, and a quaternary separation device 4 arranged in sequence. Among them, the dust removal and separation device 1 is used to separate wood chips and iron chips, the secondary separation device 2 is used to remove larger wood chips, the tertiary separation device 3 is used to further remove impurities, and the quaternary separation device 4 is mainly used to achieve oil-water separation.

[0044] According to an embodiment of the present invention, the dust removal and separation device 1 includes a dust removal box 11, a spraying device 12 arranged on the top of the dust removal box 11, a suction cup structure 13 arranged on the bottom of the dust removal box 11, and a partition device 14 located in the middle of the dust removal box 11. The partition device 14 is used to divide the inner cavity of the dust removal box 11 into two parts. In this embodiment, the partition device 14 includes a partition 141, a slider 142 connected to the partition 141, a guide rod 143 slidably engaged with the slider 142, a threaded rod 144 threadedly engaged with the slider 142, and a rotary motor 145 for driving the threaded rod 144 to rotate.

[0045] For the dust removal device for sheet processing of the present invention, when dust removal operation is required, water can be injected into the dust removal box 11 by using the spraying device 12, and the water injection volume exceeds the position where the partition 141 is located. Then, impurities such as wood chips and iron chips generated during processing can be sucked into the dust removal box 11 by a blower and enter the water, so as to realize the floating of wood chips and the sinking of iron chips, and achieve the separation of wood chips and iron chips. This way of injecting water first can effectively avoid the problem of secondary dust emission compared with the post-spraying treatment method, and injecting water first by using the spraying device 12 can clean the inner wall of the dust removal box 11 during the previous dust removal operation.

[0046] Since the wood chips float and the iron chips sink, the iron chips will be adsorbed on the suction cup structure 13. At this time, the water in the middle contains relatively few impurities or the impurity content is low. The partition 141 can be inserted into the middle of the dust removal box 11 through the partition device 14 to achieve the separation effect, so that the part containing a large amount of wood chips is located above the partition 141, and the water relatively free of impurities is located below the partition 141. An upper discharge pipe 15 and a lower discharge pipe 16 are respectively connected to the dust removal box 11. The partition device 14 is located between the upper discharge pipe 15 and the lower discharge pipe 16. The upper discharge pipe 15 is connected to the secondary separation device 2 and is used to send the water containing a large amount of wood chips to the secondary separation device 2. The lower discharge pipe 16 is connected to the tertiary separation device 3 and is used to send the relatively impurity-free water to the tertiary separation device 3 for further treatment to realize the purification and recycling of water.

[0047] According to an embodiment of the present utility model, the secondary separation device 1 includes a wastewater tank 21. An impurity bin 22 is provided in the wastewater tank 21. The impurity bin 22 is communicated with a waste discharge pipe 23, and the waste discharge pipe 23 extends outside the wastewater tank 21. A wastewater inlet pipe 24 is connected to the wastewater tank 21, and the wastewater inlet pipe 24 passes through the impurity bin 22 and is located inside the impurity bin 22. The lower end of the wastewater inlet pipe 24 is connected to a separator 28. A rotating shaft 281 is connected to the lower side of the separator 28. The rotating shaft 281 extends outside the wastewater tank 21 and is connected to a motor 282. An inclined separation pipe 283 is provided on the separator 28. A water permeable hole 221 is provided on the side wall of the impurity bin 22. The wastewater tank 21 is communicated with a purification tank 31 through a first pipeline 25. A control valve 26 and a high-pressure pump 27 are provided on the first pipeline 25.

[0048] In the wood processing dust removal device of the present invention, water containing larger wood chips enters the separator 28 through the wastewater inlet pipe 24 from the upper side discharge pipe 15. The separator 28 rotates under the drive of the motor 282. The inclined separation pipe 283 is provided on the separator 28, and the water permeable hole 221 is provided on the side wall of the impurity bin 22. Thus, the larger wood chips can be separated in the impurity bin 22 by the separator 28. The water enters the wastewater tank 21 through the impurity bin 22 and then enters the purification tank 31 through the first pipeline 25. The larger wood chips in the impurity bin 22 can be discharged through the waste discharge pipe 23. Compared with the prior art, the device can avoid the blockage of the separator by wood chips.

[0049] In the wood processing dust removal device of the present utility model, through the treatment of the above dust removal and separation device 1 and the secondary separation device 2, most of the wood chips can be removed. However, there will still be some larger wood chips or other impurities in the water, and the tertiary separation device 3 can be used for further treatment.

[0050] According to an embodiment of the present invention, the three-stage separation device 3 of the present invention includes a purification tank 31. A first accommodation chamber 5, a second accommodation chamber 6, and a third accommodation chamber 7 are provided at the bottom of the purification tank 31. A first elastic container 51, a second elastic container 61, and a third elastic container 71 are respectively provided in the first accommodation chamber 5, the second accommodation chamber 6, and the third accommodation chamber 7. The upper ends of the first elastic container 51, the second elastic container 61, and the third elastic container 71 are flush with the inner bottom of the purification tank 31, and input ports are respectively provided at the upper ends of the first elastic container 51, the second elastic container 61, and the third elastic container 71, and one-way valves are provided at the input ports. First through holes 52, second through holes 62, and third through holes 72 are respectively provided at the bottoms of the first accommodation chamber 5, the second accommodation chamber 6, and the third accommodation chamber 7. The first elastic container 51, the second elastic container 61, and the third elastic container 71 are respectively connected with a first supply pipe 53, a second supply pipe 63, and a third supply pipe 73. The first supply pipe 53, the second supply pipe 63, and the third supply pipe 73 respectively pass through the first through hole 52, the second through hole 62, and the third through hole 72 and are connected with a flocculant supply cylinder 54, an acid solution supply cylinder 64, and an alkali solution supply cylinder 74.

[0051] In the present invention, a flocculant, an acid solution, and an alkali solution are respectively contained in the first elastic container 51, the second elastic container 61, and the third elastic container 71, and a flocculant supply cylinder 54, an acid solution supply cylinder 64, and an alkali solution supply cylinder 74 are respectively connected for feeding. Since the first elastic container 51, the second elastic container 61, and the third elastic container 71 are elastic containers, when subjected to an external force, the liquid in the container is input into the purification tank 31 through the upper input port. When the external force is withdrawn, the elastic container resets, and thus automatic feeding of the flocculant, the acid solution, and the alkali solution can be realized.

[0052] In the present invention, a first threaded hole 311, a second threaded hole 312, and a third threaded hole 313 are provided on the side wall of the purification tank 31. The first threaded hole 311, the second threaded hole 312, and the third threaded hole 313 are respectively communicated with the first accommodation chamber 5, the second accommodation chamber 6, and the third accommodation chamber 7. A first threaded rod 81, a second threaded rod 82, and a third threaded rod 83 are respectively fitted on the first threaded hole 311, the second threaded hole 312, and the third threaded hole 313. Scales are provided on the first threaded rod 81, the second threaded rod 82, and the third threaded rod 83.

[0053] The dust removal device for sheet processing of the present invention, through the above settings, can control the addition amounts of the flocculant, acid solution and alkali solution by adjusting the matching degrees of the first threaded rod 81, the second threaded rod 82 and the third threaded rod 83 with the first threaded hole 41, the second threaded hole 42 and the third threaded hole 43. The first threaded rod 81, the second threaded rod 82 and the third threaded rod 83 are all provided with scales, which can ensure the accuracy of the addition amounts of the flocculant, acid solution and alkali solution, and thus can ensure the treatment effect. After one extrusion addition, the first threaded rod 81, the second threaded rod 82 and the third threaded rod 83 can be rotated in the reverse direction to reset the first elastic container 51, the second elastic container 61 and the third elastic container 71 for automatic feeding, and then the first elastic container 51, the second elastic container 61 and the third elastic container 71 can be extruded according to needs. Compared with continuously extruding the first elastic container 51, the second elastic container 61 and the third elastic container 71, this setting can ensure the accuracy of each addition amount.

[0054] For the dust removal device for sheet processing of the present invention, adding the flocculant will affect the PH, so the PH value needs to be adjusted. Taking the adjustment of acid-base balance as an example: Use a PH detection instrument to detect the wastewater in the purification tank 31. If acid solution needs to be added for adjustment, rotate the second threaded rod 82 to extrude the second elastic container 61 to add a certain amount of acid solution, and then measure the PH value in the purification tank 31. If, after detection, acid solution still needs to be added, the second threaded rod 82 can be retracted to complete the automatic feeding of the second elastic container 61, and then the above process can be repeated, so as to ensure the accuracy of each addition amount of the acid solution. Compared with the prior art, it is not necessary to adjust repeatedly for many times.

[0055] As Figure 8 shown, handles 84 are provided on the first threaded rod 81, the second threaded rod 82 and the third threaded rod 83. The setting of the handles 84 facilitates the rotation of the first threaded rod 81, the second threaded rod 82 and the third threaded rod 83.

[0056] According to an embodiment of the present invention, the first accommodation chamber 5, the second accommodation chamber 6, and the third accommodation chamber 7 of the present invention are located on one side of the bottom of the purification tank 31 close to the first threaded rod 81, the second threaded rod 82, and the third threaded rod 83. Such a setting is beneficial to reducing the set lengths of the first threaded rod 81, the second threaded rod 82, and the third threaded rod 83, thereby being beneficial to improving the extrusion sensitivity of the first threaded rod 81, the second threaded rod 82, and the third threaded rod 83 to the first elastic container 51, the second elastic container 61, and the third elastic container 71 (the longer the lengths of the first threaded rod 81, the second threaded rod 82, and the third threaded rod 83, the greater the error). In addition, the first supply pipe 53, the second supply pipe 63, and the third supply pipe 73 of the present invention are respectively hermetically connected to the first through hole 52, the second through hole 62, and the third through hole 72, preventing wastewater from leaking out from the mating parts of the first supply pipe 53, the second supply pipe 63, and the third supply pipe 73 with the first through hole 52, the second through hole 62, and the third through hole 72.

[0057] Combined Figures 3-7 As shown, according to an embodiment of the present invention, a filtering device 9 is slidably connected in the purification tank 31. The filtering device 9 includes a filter plate 91 and an enclosing plate structure 92 connected to the filter plate 91. First sliding plates 93 and second sliding plates 94 are relatively arranged on the outer side of the enclosing plate structure 92. First sliding grooves 4a and second sliding grooves 4b are provided on the inner side wall of the purification tank 4 and are respectively matched with the first sliding plates 93 and the second sliding plates 94. The upper ends of the first sliding plates 93 and the second sliding plates 94 are higher than the purification tank 4.

[0058] For the sheet metal processing dust removal device of the present invention, through the arrangement of the filtering device 9, after the wastewater is purified, through the cooperation of the first sliding plates 93, the second sliding plates 94, the first sliding grooves 4a, and the second sliding grooves 4b, the filtering device 9 can be lifted out of the purification tank 4, so that the precipitate generated by flocculation can be left on the filter plate 91 and taken out. Compared with the prior art, the operation is simple and convenient, and the collection effect of the purified precipitate is good.

[0059] According to the concept of the present invention, the method of lifting the filtering device 9 out of the purification tank 31 is not limited. For example, lifting holes can be respectively provided on the first sliding plates 93 and the second sliding plates 94, and the filtering device 9 can be lifted out of the purification tank 31 by a lifting device.

[0060] According to an embodiment of the present invention, a cross plate 95 is fixedly connected to the upper ends of the first sliding plates 93 and the second sliding plates 94. A stirring device 96 is connected to the lower end of the cross plate 95. A driving device 97 is installed on the first sliding plate 93 or the second sliding plate 94 to drive the stirring device 96 to act. Such a setting can assist in stirring during the purification process, which is beneficial to improving the reaction effect.

[0061] In this embodiment, the stirring device 96 includes a fixed seat 961 installed on the lower side of the cross plate 95 and a stirring shaft 962 rotatably connected to the fixed seat 961. A plurality of stirring blades 963 are provided on the stirring shaft 962, and a linkage gear 964 is fixedly installed on the stirring shaft 962.

A driving gear 973 is installed on the driving rotating shaft 972, and the driving gear 973 meshes with the linkage gear 964. With such a setting, by driving the driving motor 971, the rotation of the stirring shaft 962 can be realized, and the stirring function can be achieved.

[0062] As Figure 1 shown, the four - stage separation device 4 of the present invention includes a collection box 41. A support plate 42 is provided inside the collection box 41. The support plate 42 is connected with an oil - removing apron 43. Leakage holes 44 are provided on the support plate 42. A condensation pipe 45 is provided on the lower side of the support plate 42. The cold pipe 45 is respectively connected with a water inlet pipe 46 and a water outlet pipe 47. A lifting mechanism 48 is provided on the lower side of the condensation pipe 45.

[0063] In the present invention, the oil - water separation is carried out by using the different solidification temperatures of oil and water. Specifically, through the condensation effect of the condensation pipe 45, the oil can be solidified, and then the support plate 42 is lifted by the lifting structure 48 to realize the separation of the solidified oil and water. The four - stage separation device 4 is mainly aimed at the situation where a large amount of oil adheres to the wood chips during the plate processing.
