Description

Technical Field

[0001] This utility model belongs to the field of environmental protection technology, and in particular relates to a printing wastewater filtration device. Background Technology

[0002] Printing wastewater is a common and complex type of industrial wastewater, mainly originating from the production processes of various printing plants. It includes waste ink, paper cleaning water, and equipment cleaning water. These wastewaters contain a large amount of particulate matter, organic matter, heavy metals, and other harmful substances, which have a serious impact on the environment and human health.

[0003] Existing printing wastewater filtration devices require wastewater to be filtered through filter elements during use. However, impurities (such as pigment particles or paper fibers) in the wastewater remain on the surface of the filter elements. After prolonged use, these impurities can block the filter elements, requiring manual cleaning by staff to remove the remaining impurities. This affects the wastewater filtration process and reduces the device's filtration efficiency.

[0004] In other words, traditional printing wastewater filtration devices require manual cleaning of impurities from the filter elements by staff during use, which affects the wastewater filtration process and reduces the device's filtration efficiency. Utility Model Content

The discharge plate is connected to the outer shell of the filter equipment through the blade housing.

[0010] As a preferred embodiment of the above technical solution, a collection component is also included. The collection component includes a mounting plate, a collection box, a barrier plate, and screws. The mounting plate is connected to the housing of the filter device. The collection box slides on the mounting plate through the cooperation of the mounting plate. The barrier plate is connected to the side of the housing of the filter device through the cooperation of the screws.

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0025] Example 1

[0026] This utility model provides a printing wastewater filtration device, such as... Figures 1 to 5 As shown, the system includes: a filter housing 1, a collection tank 2, and a filter assembly. The filter housing 1 serves as the overall frame of the wastewater filtration device. The collection tank 2 is connected to the filter housing 1 and is used to collect the filtered wastewater. The filter assembly includes a filter element 3, a connecting seat 4, a driving component 5, a spiral blade 6, a blade housing 7, and a discharge plate 8. The filter element 3 is a metal filter screen. The driving component 5 is a servo motor. The spiral blade 6 is connected to the output end of the driving component 5. The connection between the connecting seat 4 and the spiral blade 6 is provided with a sealing structure that does not affect the rotation of the spiral blade 6 inside the connecting seat 4. The discharge plate 8 is located near the top of the surface of the blade housing 7. The surface of the blade housing 7 has an opening, and the opening... The position of the spiral blade 6 is horizontal with the discharge plate 8. The discharge plate 8 has an inclined surface inside. The part of the spiral blade 6 above the blade shell 7 is solid and fits against the inner wall of the blade shell 7. The drive component 5 is connected to the inside of the filter element 3 through the connecting seat 4. The filter element 3 is connected to the top of the collection tank 2. With the cooperation of the drive component 5 and the spiral blade 6, the spiral blade 6 rotates in the connecting seat 4 and the blade shell 7. The discharge plate 8 is connected to the filter equipment shell 1 through the blade shell 7. The filter element 3 is conical. A cylinder is provided at the center of the bottom of the filter element 3 and the cylinder is interconnected with the filter element 3. The connecting seat 4 is connected to the inside of the cylinder. The blade edge of the spiral blade 6 fits against the inner wall of the blade shell 7.

[0027] The impurities (pigment particles or paper fibers, etc.) filtered by the filter element 3 are collected by the spiral blades 6, which reduces the need for workers to manually disassemble and replace the filter element 3, thereby making the process of processing impurities (pigment particles or paper fibers, etc.) smoother and improving the processing efficiency of the device.

[0028] In operation, the operator first pumps the wastewater to be treated into the housing 1 of the filter equipment using a water pump. This wastewater is then discharged along the feed pipe onto the surface of the filter element 3. At this point, the wastewater flows along the inclined surface of the filter element 3 towards the center, and is filtered by the filter element 3. Residual impurities (pigment particles or paper fibers, etc.) continue to flow along the inclined surface of the filter element 3 towards the center. When these impurities (pigment particles or paper fibers, etc.) fall into the cylinder, the operator activates the drive unit 5. The drive unit 5 drives the spiral blades 6 to rotate, and the rotating spiral blades 6 carry the impurities (pigment particles or paper fibers) into the cylinder. The impurities (such as pigment particles or paper fibers) rise along the inner wall of the blade shell 7. When these impurities rise to the position of the discharge plate 8, they will flow towards the discharge plate 8 through the opening of the blade shell 7 and be discharged through the discharge plate 8, thus completing the process of collecting impurities on the surface of the filter element 3. The impurities (such as pigment particles or paper fibers) filtered by the filter element 3 are collected by the spiral blades 6, which reduces the need for workers to manually disassemble and replace the filter element 3, thereby making the process of processing impurities (such as pigment particles or paper fibers) smoother and improving the processing efficiency of the device.

[0029] Specifically, a collection bucket 2 is fixedly connected inside the filter housing 1. A filter element 3 is installed on the top of the collection bucket 2. A connecting seat 4 is installed at the center of the filter element 3 by screws. A spiral blade 6 is rotatably connected inside the connecting seat 4. The top of the spiral blade 6 is snapped into the output end of the drive element 5. The drive element 5 is fixedly connected inside the filter housing 1. The discharge plate 8 is fixedly connected inside the filter housing 1 through the blade housing 7.

[0030] In the above example, the existing filter equipment housing 1 is also equipped with a feed pipe and a water pump. The water pump is connected to the feed pipe, which is located above the filter element 3. The working principle and working process described above are existing technologies in this field and will not be repeated here.

[0031] To address the issue of collecting discharged impurities (pigment particles or paper fibers, etc.) as described in the above example, the following solution is proposed: Figure 3 and Figure 5As shown, it also includes a collection assembly, which includes a mounting plate 9, a collection box 10, a barrier plate 11, and screws 12. The mounting plate 9 is sleeved on the outer surface of the blade housing 7 and connected to the filter housing 1. The collection box 10 slides on the mounting plate 9 through the cooperation of the mounting plate 9. The barrier plate 11 is connected to the side of the filter housing 1 through the cooperation of the screws 12. The screws 12 penetrate the interior of the barrier plate 11 and the side of the filter housing 1. There are four screws 12, which are distributed at the corners of the barrier plate 11. The mounting plate 9 has three grooves, and the collection box 10 has three protrusions. The three protrusions and the three grooves are interlocked to restrict the movement of the collection box 10 on the surface of the mounting plate 9. The area of ​​the barrier plate 11 is larger than the side area of ​​the collection box 10. The mounting plate 9 has a connecting plate 13, which is located at both ends of the mounting plate 9.

[0032] The collection box 10 collects the discharged impurities (pigment particles or paper fibers, etc.), avoiding the need for staff to manually clean up these discharged impurities (pigment particles or paper fibers, etc.), thereby reducing the time spent on manual cleaning of impurities and improving the efficiency of the device in handling impurities (pigment particles or paper fibers, etc.).

[0033] During operation, impurities (pigment particles or paper fibers, etc.) flowing along the opening of the blade housing 7 towards the discharge plate 8 will continue to flow along the inclined surface of the discharge plate 8. These impurities will fall into the collection box 10 for collection. When the device stops operating, the operator removes the four screws 12 and then removes the baffle plate 11, creating an outlet on the side of the filter housing 1. The operator then pulls the collection box 10 containing the impurities (pigment particles or paper fibers, etc.), moving it towards the outlet. As the collection box 10 moves, it drives three protrusions. Sliding within the three grooves inside the mounting plate 9, after the collection box 10 is removed, the operator cleans the impurities inside the collection box 10 and reverses the above steps to install the collection box 10 inside the filter housing 1, thus completing the process of collecting impurities (pigment particles or paper fibers, etc.) discharged from the discharge plate 8. By collecting the discharged impurities (pigment particles or paper fibers, etc.) through the collection box 10, the operator avoids the need to manually clean these discharged impurities (pigment particles or paper fibers, etc.), thereby reducing the time spent on manual cleaning of impurities and improving the efficiency of the device in processing impurities (pigment particles or paper fibers, etc.).

[0034] Specifically, an installation plate 9 is fixedly connected inside the filter housing 1. The installation plate 9 is sleeved on the outer surface of the blade housing 7. A collection box 10 is slidably connected to the surface of the installation plate 9. A barrier plate 11 is installed on the side of the filter housing 1 by screws 12. The barrier plate 11 and the collection box 10 are in a horizontal direction. A connecting plate 13 is fixedly connected to both ends of the installation plate 9.

[0035] Working principle: When using this device, the operator first pumps the wastewater to be treated into the filter housing 1 using a water pump. This wastewater is discharged along the feed pipe to the surface of the filter element 3. At this time, the wastewater flows along the inclined surface of the filter element 3 towards the center position and is filtered by the filter element 3. The remaining impurities (pigment particles or paper fibers, etc.) continue to flow along the inclined surface of the filter element 3 towards the center position. When these impurities (pigment particles or paper fibers, etc.) fall into the cylinder, the operator activates the drive unit 5. The drive unit 5 drives the spiral blade 6 to rotate. When the spiral blade 6 rotates, it drives the impurities (pigment particles or paper fibers, etc.) inside the cylinder to rise along the inner wall of the blade housing 7. When these impurities (pigment particles or paper fibers, etc.) rise to the position of the discharge plate 8, they will flow along the opening of the blade housing 7 towards the discharge plate 8. At this time, these impurities (pigment particles or paper fibers, etc.) will continue to flow along the inclined surface of the discharge plate 8. Pigment particles or paper fibers, etc., will fall into the collection box 10 for collection. When the device stops operating, the operator removes the four screws 12 and then removes the baffle plate 11, so that an outlet is formed on the side of the filter housing 1. At this time, the operator pulls the collection box 10 containing impurities (pigment particles or paper fibers, etc.) to move the collection box 10 towards the outlet. When the collection box 10 moves, it drives the three protrusions to slide in the three grooves inside the mounting plate 9. After the collection box 10 is removed, the operator cleans the impurities inside the collection box 10 and reverses the above steps to install the collection box 10 inside the filter housing 1, thus completing the process of collecting impurities on the surface of the filter element 3. The impurities (pigment particles or paper fibers, etc.) filtered by the filter element 3 are collected by the spiral blades 6, which reduces the need for the operator to manually disassemble and replace the filter element 3, thereby making the process of processing impurities (pigment particles or paper fibers, etc.) smoother and improving the processing efficiency of the device.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
