Description

Technical Field

[0001] This invention relates to a filter press solids separation device. Background Technology

[0002] Concrete is the largest component of building materials, used in the largest quantities in construction projects. It is primarily composed of four basic materials: cement, water, aggregate, and sand. During concrete production, excess concrete and unusable waste concrete due to quality issues are inevitable. Improper handling of these waste concrete materials will cause permanent environmental pollution. Currently, an ideal concrete recycling system separates and recovers the sand and aggregate from the waste concrete, returning them to the system for re-batch production. The clean water from the separated slurry can also be reused. However, existing concrete recycling systems cannot complete the washing and screening of sand and aggregate in one operation. Multiple manual operations are required to collect and discharge materials into the separator for screening, resulting in low screening efficiency. Summary of the Invention

The bottom of the filter press chamber 8 is provided with a feed inlet 8-3 and a discharge outlet 8-4.

[0021] The bottom of the filter chamber 3 of the filter mechanism is connected to the inlet 8-1 of the first filter press assembly through the first pipe 9. The outlet 8-2 of the filter press assembly is connected to the inlet 8-1 of the adjacent filter press assembly through the second pipe 10.

One-way valves 23 are provided on the first pipe 9, the second pipe 10, the third pipe 11 and the fourth pipe 12.

[0022] The weighing mechanism includes a receiving box 13, inside which are a support plate 14, a spring 15, and a telescopic rod 16. The support plate 14 is located inside the receiving box 13 and is slidably connected to the inner wall of the receiving box 13. The support plate 14 is connected to the bottom of the receiving box 13 through the spring 15 and the telescopic rod 16. A pressure sensor 17 is provided on the top of the spring 15. One end of the spring 15 abuts against the lower surface of the support plate 14 through the pressure sensor 17, and the other end of the spring abuts against the bottom of the receiving box 13. The two ends of the telescopic rod 16 are fixed to the lower surface of the support plate 14 and the bottom of the receiving box 13, respectively. The top of the receiving box 13 is provided with a collection port 13-1. The discharge port 8-2 of the last set of filter press components is connected to the fourth pipeline 12, the collection port 13-1 of the receiving box 13, and the discharge port 8-4 of the last set of filter press components. The discharge port 8-4 of the last set of filter press components discharges through the fifth pipeline 18.

[0023] It also includes a housing 19 and a base 20. The filtration mechanism, the filter pressing mechanism and the weighing mechanism are all set inside the housing 19. The base 20 is fixed to the bottom of the housing 19. The cylinder body of the cylinder 6 is fixed on the housing 19. The receiving box 13 is fixed inside the housing 19 by the frame 24.

[0024] The drive assembly includes a motor 21 and a belt 22. The feed pipe 4 is connected to the output end of the motor 21 via the belt 22.

[0025] The bottom of the receiving box 13 is provided with a material discharge and recycling port 13-2.

[0026] The discharge port 8-2 of the last filter press assembly is connected to the discharge port 8-4 of the last filter press assembly through the sixth pipeline 25. Both the fifth pipeline 18 and the sixth pipeline 25 are equipped with one-way valves 23, and the fifth pipeline 18 is also equipped with a water pump 28.

[0027] like Figure 4-5 As shown, the screen 2 has a stirring assembly, which includes a rotating shaft 26 and several rotating rods 27. One end of the rotating shaft 26 is connected to the feed pipe 4, and the rotating rods 27 are evenly distributed on the other end of the rotating shaft 26.

[0028] The filter press solids separation device of the present invention is used to separate sand and gravel and slurry in concrete mortar. The working process is as follows:

[0029] First, concrete mortar is poured into the feed hopper 1 of the filter mechanism. The concrete mortar enters the funnel-shaped screen 2. The motor 21 of the drive component drives the belt 22, causing the discharge pipe 4 to rotate. The rotation of the discharge pipe 4 drives the screen 2 to rotate, thus throwing the slurry in the concrete mortar in the screen 2 into the filter chamber 3. The stones in the concrete mortar are retained in the screen 2. The stones can enter the discharge pipe 4 through the lower opening of the screen 2, and then enter the discharge pipe 5 from the discharge pipe 4, thus realizing the discharge of the stones. The mortar in the filter chamber 3 enters the feed port 8-1 of the first set of filter press components of the filter press mechanism from the bottom of the filter chamber 3 through the first pipe 9. The first pipe 9 is equipped with a one-way valve to prevent the mortar from flowing back. The mortar enters the first set of filter press components. The cylinder of the first set of filter press components extends upward, causing the filter piston 7 to move upward, thereby reducing the volume of the filter chamber 8 and squeezing the mortar entering the filter chamber 8. During the squeezing process, the filter screen 7-1 of the filter piston 7 filters the mortar, and the through hole 7-3 of the piston body 7-2 allows the liquid to seep out and discharge downward. The mortar retained above the filter screen 7-1 will enter the inlet 8-1 of the second set of filter press components through the outlet 8-2. The mortar liquid that seeps downward can be discharged from the outlet 8-4 at the bottom of the filter chamber 8 to the inlet 8-3 of the second set of filter press components. The inlet 8-3 of the first set of filter press components does not need to be filled and can be sealed. The mortar passes through each filter press component in sequence for filtration. The sand in the mortar will be retained on the filter screen 7-1 of each filter press component and carried to the next filter press component by the subsequent mortar flushing. When reaching the last set of filter press components, the sand remaining above the filter screen 7-1 enters the collection port 13-1 of the receiving box 13 of the weighing mechanism from its discharge port 8-2. Alternatively, it can flow downwards through the sixth pipe 25 into the fifth pipe 18 and be directly discharged. It can also flow back through the fourth pipe 12 to the inlet 8-1 of the first set of filter press components for another filtration process. The flow path depends on the filtration status of the mortar. If the mortar liquid seeping downwards from the last set of filter press components meets the slurry discharge standard, it can be directly discharged through the fifth pipe 18. The water pump 28 improves the drainage efficiency. The sand entering the receiving bin 13 of the weighing mechanism actually enters the space between the receiving bin 13 and the support plate 14. The support plate 14 is supported by springs 15 and telescopic rods 16. The telescopic rods 16 only provide balance on both sides of the springs 15, and the actual pressure is borne by the springs 15. The pressure sensor 17 between the springs 15 and the lower surface of the support plate 14 can detect the pressure at its location. This pressure is related to the weight borne by the support plate 14, so the opening and closing of the discharge port 13-2 of the receiving bin 13 can be controlled according to the pressure. When a certain amount of sand is collected in the receiving bin 13, the discharge port 13-2 can be opened to discharge the sand.

[0030] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
