Description

Technical Field

[0001] The present application relates to the technical field of animal husbandry, and in particular to a drum-type solid-liquid separator. Background Art

[0002] A solid-liquid separator is a device used to separate the residue and liquid from animal manure, high-concentration organic wastewater from slaughterhouses, and other intensive animal husbandry such as chicken, cattle, and horses. In response to the requirements of new rural development and the growing awareness of environmental protection and energy conservation, farms now typically treat manure and urine through the construction of biogas and biochemical tanks. Untreated manure and urine entering the biogas tanks significantly increases the organic load per unit volume and results in suboptimal treatment results, requiring a significant increase in the tank's volume. Therefore, pre-treatment of manure to separate solids and liquids is necessary. This not only addresses the problem of manure sedimentation in the biogas tanks, improving their processing capacity, but also reduces the footprint of the biogas and biochemical tanks.

[0003] However, the solid-liquid mixture produced in livestock farms currently undergoes only a single solid-liquid separation operation, which results in inadequate filtration of some residual water and unsatisfactory subsequent fermentation results. Furthermore, the solid-liquid mixture can adhere to the filter structure, causing clogging and reducing filtration efficiency. Utility Model Content

[0004] In order to achieve sufficient separation of solid and liquid and improve the efficiency of solid-liquid separation, the present application provides a drum-type solid-liquid separator.

[0005] The present application provides a drum-type solid-liquid separator adopting the following technical solution:

[0006] The filter press of claim 1, wherein the filter press has a first end in contact with the filter element and a second end in contact with the filter element. The filter press has a first end in contact with the filter element and a second end in contact with the filter element. The first end in contact with the filter element has a first end in contact with the filter element. The filter press has a first end in contact with the filter element. The filter press has a first end in contact with the filter element.

[0007] By adopting this technical solution, the material enters the first filter cartridge for primary filtration. The spiral conveyor plate then transfers the filtered material through a feed pipe to the second filter cartridge in the second filter box. The material then undergoes secondary filtration in the second filter cartridge and ultimately exits the second filter box through the outlet. The coordinated operation of the first and second filter boxes, the primary and secondary filter assemblies, achieves multi-stage, comprehensive filtration of the material, effectively separating solids and liquids and improving their efficiency.

[0008] Optionally, a flushing pipe is provided in the first filter box along the length direction of the first filter cartridge, and a plurality of flushing nozzles are connected to the flushing pipe, and the flushing nozzles are arranged toward the direction of the first filter cartridge.

[0009] By adopting the above technical solution, cleaning water is sprayed onto the first filter cartridge through the flushing pipe and the flushing nozzle to clean it, thereby reducing the possibility of material adhering to the first filter cartridge and causing its filtration efficiency to decrease.

[0010] Optionally, a material blocking assembly is provided at one end of the second filter box away from the material delivery pipe, and the material blocking assembly includes a mounting frame and a baffle. The mounting frame is provided on the material outlet of the second filter box, and the baffle is symmetrically rotatably provided on both sides of the opposite sides of the mounting frame.

[0011] By adopting this technical solution, the baffle is closed before filtration, allowing the material that has undergone two filtrations to accumulate in the second filter cartridge. As the material in the second filter cartridge increases, the baffle opens, pushed by the solid material, and the material is discharged from the outlet. The provision of the material retaining assembly prevents insufficiently filtered solid material from directly exiting the second filter cartridge, thereby improving the filtration efficiency of the material.

[0012] Optionally, a connecting frame is provided on the second filter box, and an operating frame is rotatably provided on the connecting frame. The operating frame includes two rotating sections rotatably connected to the connecting frame and an abutment section provided between the two rotating sections. The abutment section is provided on the side of one of the baffles away from the second filter box. A connecting rod is provided between the two rotating sections, and the connecting rod is provided on the side of the other baffle away from the second filter box.

[0013] By adopting this technical solution, to close the baffles, the upper end of the operating frame is first rotated, and the abutment section pushes one baffle until it blocks the discharge port. The operating frame is then rotated in the opposite direction, and the connecting rod pushes the other baffle until it blocks the discharge port. The arrangement of the operating frame and connecting rod eliminates the need for direct manual contact with the baffles and reduces the labor involved in turning the baffles.

[0014] Optionally, the bottom surface of the first filter box is arranged in an inverted cone shape, the lowest point of the first filter box is connected to a first drain pipe, and the bottom surface of the second filter box is connected to a second drain pipe.

[0015] By adopting the above technical solution, the inverted cone-shaped bottom of the first filter box facilitates the discharge of filtered water from the first drain pipe, and the water filtered from the second filter cartridge is discharged through the second drain pipe, thereby achieving solid-liquid separation of the material.

[0016] Optionally, a cleaning assembly is provided in the first filter box, and the cleaning assembly includes a cleaning shaft and a cleaning brush. The cleaning shaft is rotatably connected to the first filter box and is arranged parallel to the first filter cartridge. The cleaning brush is arranged on the cleaning shaft, and the first filter box is provided with a driving source for driving the cleaning shaft to rotate.

[0017] By adopting the above technical solution, the driving member drives the cleaning shaft and the cleaning brush to rotate, and the cleaning brush cleans the surface of the first filter cartridge, which helps to improve the cleaning efficiency of the first filter cartridge and reduce the possibility of impurities clogging the first filter cartridge.

[0018] Optionally, a filter plate is provided in the first filter box, and the filter plate is provided below the cleaning shaft and the first filter cartridge.

[0019] By adopting the above technical solution, the filter plate filters the solid impurities flushed and swept down, thereby reducing the possibility of the impurities clogging the first drain pipe.

[0020] Optionally, the top end of the feed pipe extends into the first filter box and is connected to a feed hopper, the feed hopper is arranged corresponding to one end of the first filter cartridge, a supporting opening is provided on the feed hopper, and one end of the first filter cartridge is rotatably overlapped in the supporting opening.

[0021] By adopting the above technical solution, the provision of the feed hopper reduces the possibility that the material in the first filter cartridge directly falls into the first filter box.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Through the mutual cooperation of the first filter box, the second filter box, the first filter assembly and the second filter assembly, multi-stage full filtration of the material is achieved, which has the effect of achieving full separation of solid and liquid and improving the efficiency of solid-liquid separation;

[0024] 2. The setting of the material retaining assembly prevents the solid materials that are not fully filtered from being directly discharged from the second filter cartridge, which helps to improve the filtering effect of the materials;

[0025] 3. The setting of the feed hopper reduces the possibility that the material in the first filter cartridge falls directly into the first filter box. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Reference Figure 2 A feed pipe 11 is provided on the bottom surface of the first filter box 1 at the end away from the feed pipe 7. The top end of the feed pipe 11 extends into the first filter box 1 and is connected to a feed hopper 12.

The end of the first filter cartridge 33 away from the feed pipe 7 is rotatably overlapped in the support opening 121. One end of the second filter box 2 in the longitudinal direction is connected to the bottom end of the feed pipe 11. A base frame 13 is provided at the bottom end of the second filter box 2. A second drain pipe 15 for drainage is connected to the bottom surface of the second filter box 2.

[0037] Reference Figure 2 and Figure 3 The secondary filter assembly 4 is arranged in the second filter box, and the secondary filter assembly 4 includes a second motor 41, a spiral conveying rod 42 and a second filter cartridge 43. The second filter cartridge 43 is arranged in the second filter box 2 along the length direction of the second filter box 2, and the end of the second filter box 2 away from the feed pipe 11 is provided with a discharge port 21 connected to one end of the second filter cartridge 43. The end of the second filter cartridge 43 away from the discharge port 21 is connected to the bottom end of the feed pipe 11, and the filtration gap of the second filter cartridge 43 is smaller than the filtration gap of the first filter cartridge 33. The spiral conveying rod 42 is rotatably arranged in the second filter cartridge 43, and the spiral conveying rod 42 is fitted with the inner ring wall of the second filter cartridge 43. One end of the spiral conveying rod 42 extends into the inner cavity of the feed pipe 11. The second motor 41 is arranged on the base frame 13, and the output shaft of the second motor 41 is transmission-connected to one end of the spiral conveying rod 42.

[0038] Reference Figure 2 and Figure 3 The material blocking assembly 5 is arranged on the second filter box 2, and the material blocking assembly 5 includes a mounting frame 51, a baffle 52, a connecting frame 53, an operating frame 54 and a connecting rod 55. The mounting frame 51 is arranged on the second filter box 2 and is connected to the discharge port 21. The baffle 52 is rotatably connected to each other on both sides opposite to the mounting frame 51. The connecting frame 53 is installed at one end of the second filter box 2 where the mounting frame 51 is provided, and the operating frame 54 is provided on the connecting frame 53. The operating frame 54 includes two rotating sections 541 and an abutting section 542 arranged between the two rotating sections 541. The two rotating sections 541 are rotatably connected to the connecting frame 53, and the abutting section 542 is arranged on the side of the lower baffle 52 away from the second filter box 2. The connecting rod 55 is connected between the two rotating sections 541, and the connecting rod 55 is arranged on the side of the upper baffle 52 away from the second filter box 2.

[0039] Reference Figure 1 and Figure 2 During solid-liquid separation, the solid-liquid mixture enters the interior of the first filter cartridge 33 through the feed pipe 7. The first motor 31 starts and drives the connected first filter cartridge 33 to rotate. The material undergoes solid-liquid separation under the action of the first filter cartridge 33, and the separated liquid flows out through the first drain pipe 8. The material after preliminary solid-liquid separation is conveyed by the spiral conveyor plate 34 and enters the conveying pipe 11 through the feed hopper 12. The provision of the feed hopper 12 reduces the possibility of material falling out of the first filter cartridge 33 during the conveying process. Cleaning water is sprayed onto the first filter cartridge 33 through the flushing pipe 9 and a plurality of flushing nozzles 10, thereby cleaning the first filter cartridge 33 and reducing the possibility of material adhering to the first filter cartridge 33 and affecting its normal filtration efficiency.

[0040] Reference Figure 2 and Figure 3 , the second motor 41 is started, and the spiral conveying rod 42 conveys the material that falls into the bottom end of the feed pipe 11 to the second filter cartridge 43 for secondary filtration to remove the residual water therein, and the water generated by the filtration is discharged through the second drain pipe 15 provided at the bottom end of the second filter box 2. The material that has undergone secondary filtration moves to the end of the second filter box 2 close to the mounting bracket 51, and at this time the baffle 52 is in a closed state. As the amount of material in the second filter cartridge 43 increases, the baffle 52 flips outward and opens under the pressure of the material, and the material is discharged from the second filter box 2 through the discharge port 21. The setting of the material baffle assembly 5 ensures that the material that has not been fully squeezed for solid-liquid separation will not be directly discharged from the first filter cartridge 33, thereby achieving sufficient solid-liquid separation of the material.

[0041] Reference Figure 2 and Figure 3After a period of filtration, when the machine stops operating, the two baffles 52 need to be closed. The operating frame 54 is rotated so that the abutment section 542 of the operating frame 54 pushes the lower baffle 52 toward the mounting frame 51 until the lower baffle 52 blocks the discharge port 21. The operating frame 54 is then rotated in the opposite direction, and the connecting rod 55 provided on the operating frame 54 pushes the upper baffle 52, causing it to block the discharge port 21. The arrangement of the operating frame 54 and the connecting rod 55 prevents the operator from directly touching the baffles 52 with their hands when closing them, and also makes closing the baffles 52 more labor-efficient.

[0042] The operating principle of a drum-type solid-liquid separator in Example 1 of the present application is as follows: when performing solid-liquid separation of materials, the solid-liquid mixture enters the interior of the first filter cartridge 33 through the feed pipe 7 for solid-liquid separation, and the material that has undergone preliminary separation enters the feed pipe 11. The spiral conveying rod 42 transports the material that falls into the bottom end of the feed pipe 11 to the second filter cartridge 43 for secondary filtration. As the material in the second filter cartridge 43 increases, the baffle 52 opens under the pressure of the material, and the material is discharged from the second filter box 2. The setting of the material baffle assembly 5 ensures that the material that has not been fully squeezed and separated from the solid and liquid will not be directly discharged from the first filter cartridge 33, thereby achieving sufficient solid-liquid separation of the material.

[0043] Example 2

[0044] Reference Figure 4 The difference between Example 2 and Example 1 is that a cleaning assembly 6 is provided in the first filter box 1, and the cleaning assembly 6 includes a cleaning motor 61, a cleaning shaft 62, and a cleaning brush 63. The cleaning shaft 62 is rotatably disposed along the length of the first filter box 1 between two opposite vertical side walls of the first filter box 1. The cleaning motor 61 is connected to the first filter box 1, and the output shaft of the cleaning motor 61 is drivingly connected to one end of the cleaning shaft 62. The cleaning brush 63 is disposed on the cleaning shaft 62 and is disposed in contact with the outer wall of the first filter cartridge 33.

[0045] Reference Figure 4 A filter plate 14 is horizontally arranged in the first filter box 1 , and the filter plate 14 is arranged below the cleaning brush 63 and the first filter cartridge 33 .

[0046] The operating principle of the drum-type solid-liquid separator in Example 2 of the present application is as follows: while flushing the first filter cartridge 33, the cleaning motor 61 is activated to drive the cleaning shaft 62 and the cleaning brush 63 to rotate, and the cleaning brush 63 cleans the outer wall of the first filter cartridge 33, further improving the cleaning effect of the first filter cartridge 33. The filter plate 14 filters the solid impurities flushed and swept, reducing the possibility of impurities falling into the first drain pipe 8 and causing it to clog.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
