Abstract
Description
Technical Field
[0001] This patent relates to the field of water sludge filtration, specifically a multi-layer water sludge filtration device. Background Technology
[0002] Water slag is formed by rapidly cooling molten blast furnace slag in water. After the molten slag is granulated into water slag in front of the furnace, the slag-water mixture needs to be filtered through a filtration device to remove the water slag.
[0003] However, in existing filtration devices, water residue cannot be discharged in time during the filtration process, which can easily clog the filter holes on the filter plate, resulting in water not being filtered and discharged in time, thus affecting the normal operation of the filtration device. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this patent is to provide a multi-layer filtration device for water sludge.
[0005] The technical solution adopted by this patent to solve its technical problem is: a multi-layer water slag filtration device, including a cylinder, a cover installed at the upper end of the cylinder, a water slag filtration mechanism installed on the lower wall of the cover, and a slag discharge mechanism sleeved on the outer side of the cylinder.
[0006] The slag discharge mechanism includes a collecting sleeve, a slag discharge groove, and a filter ring. The collecting sleeve is sleeved on the outside of the cylinder. The inner side wall of the collecting sleeve is provided with a slag discharge groove, which penetrates the side wall of the cylinder. The inner wall at the lower end of the collecting sleeve is provided with an internal thread, and the outer side wall at the upper end of the filter ring is provided with an external thread. The filter ring is screwed into the collecting sleeve by the thread.
[0007] A water inlet pipe is inserted into the upper wall of the cover and is connected to an external pipeline. A drain pipe is inserted into the side wall of the cylinder.
[0008] Furthermore, the water slag filtration mechanism includes a fixed frame, a filter screen, and a sealing ring. The fixed frame is rotatably mounted on the lower wall of the cover. The filter screen is installed on the inner side wall of the fixed frame. The sealing ring is fitted onto the outer side wall of the filter screen. The sealing ring is in contact with the inner side wall of the cylinder. The filter screen is located below the slag discharge trough.
[0009] Furthermore, the filter ring includes a ring body, a slot, and an annular filter screen. The ring body is screwed into the collecting sleeve, and a slot is formed on the upper wall of the ring body. An annular filter screen is installed on the inner wall of the slot.
[0010] Furthermore, the lower wall of the ring is inserted into one end where the water outlet pipe is installed, and the other end of the water outlet pipe passes through the upper wall of the drain pipe and is connected to the inner cavity of the drain pipe.
[0011] Furthermore, it also includes a base, the upper wall of which has a placement groove, and the cylindrical body is inserted and installed in the placement groove.
[0012] Furthermore, a submersible motor is installed on the inner wall of the cylinder. The submersible motor is electrically connected to an external power source, and the output end of the submersible motor is installed on the lower wall of the fixed frame.
[0013] The beneficial effects of this patent are:
[0014] This device uses a collection sleeve and a slag discharge trough on the outside of its cylinder to allow the slag-water mixture to be discharged into the cylinder. The slag and water are blocked by the filter screen, and then the slag is thrown into the collection sleeve by the rotation of the slag and water filtration mechanism. This avoids the filter screen from becoming clogged and affecting the filtration of the slag-water mixture.
[0015] Additionally, a filter ring is installed below the collecting sleeve, which can perform secondary filtration on the water sludge, causing the water droplets attached to the sludge to fall into the empty trough, and then enter the drain pipe through the outlet pipe on the empty trough for discharge.

[0020] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.
[0021] See Figure 1 , Figure 2 , Figure 3This is a schematic diagram of the structure of this patent. A multi-layer water slag filtration device includes a cylinder 1, a cover 2 installed at the upper end of the cylinder 1, a water slag filtration mechanism 3 installed on the lower wall of the cover 2, and a slag discharge mechanism 4 sleeved on the outer side of the cylinder 1.
[0022] The external sludge-water mixture is discharged into the cylinder 1 through the water inlet pipe 5, and then separated from the water by the internal water sludge filtration mechanism 3. During the filtration process, the water sludge can directly enter the collection sleeve 41 through the sludge outlet 42, thereby avoiding the clogging of the filter screen 32 and affecting the filtration efficiency of the device.
[0023] The slag discharge mechanism 4 includes a collecting sleeve 41, a slag discharge groove 42, and a filter ring 43. The collecting sleeve 41 is sleeved on the outside of the cylinder 1. The inner side wall of the collecting sleeve 41 is provided with a slag discharge groove 42, which penetrates the side wall of the cylinder 1. The inner wall at the lower end of the collecting sleeve 41 is provided with an internal thread, and the outer side wall at the upper end of the filter ring 43 is provided with an external thread. The filter ring 43 is screwed into the collecting sleeve 41 by the thread.
[0024] The filtered water residue will be swung through the residue outlet 42 into the collection sleeve 41 and fall onto the filter ring 43. At the same time, the filter ring 43 can also perform secondary filtration on the water residue to improve the filtration effect.
[0025] A water inlet pipe 5 is inserted into the upper wall of the cover 2 and is connected to an external pipeline. A drain pipe 6 is inserted into the side wall of the cylinder 1.
[0026] The water slag filtration mechanism 3 includes a fixed frame 31, a filter screen 32 and a sealing ring 33. The fixed frame 31 is rotatably installed on the lower wall of the cover 2. The filter screen 32 is installed on the inner side wall of the fixed frame 31. The sealing ring 33 is sleeved on the outer side wall of the filter screen 32. The sealing ring 33 is in contact with the inner side wall of the cylinder 1. The filter screen 32 is located below the slag discharge trough 42.
[0027] In this paper, the filter plate 32 has multiple layers, and the size of the holes decreases layer by layer, which improves the filtration effect of the device.
[0028] The filter ring 43 includes a ring body 431, a groove 432 and an annular filter screen 433. The ring body 431 is screwed into the collection sleeve 41. The upper wall of the ring body 431 is provided with a groove 432, and the inner wall of the groove 432 is equipped with an annular filter screen 433.
[0029] The water sludge entering the collection sleeve 41 will fall above the annular filter screen 433. The water droplets attached to the water sludge will pass through the annular filter screen 433 and fall into the empty trough 432. Then, it will be discharged into the drain pipe 6 through the water outlet pipe 7 in the empty trough 432, thus completing the secondary filtration of the water sludge.
[0030] When it is necessary to clean the water residue inside the collecting sleeve 41, the ring 431 can be directly unscrewed from the collecting sleeve 41 to discharge the water residue inside the collecting sleeve 41, which is very convenient.
[0031] One end of the water outlet pipe 7 is inserted into the lower wall of the ring body 431, and the other end of the water outlet pipe 7 passes through the upper wall of the drain pipe 6 and is connected to the inner cavity of the drain pipe 6.
[0032] It also includes a base 8, the upper wall of which has a placement groove 9, and the cylinder 1 is inserted into the placement groove 9.
[0033] A submersible motor 10 is installed on the inner wall of the cylinder 1. The submersible motor 10 is electrically connected to an external power source. The output end of the submersible motor 10 is installed on the lower wall of the fixed frame 31.
[0034] By setting a submersible motor 10, it can drive the fixed frame 31 to rotate, so that the water residue on the filter screen plate 32 can be thrown out from the residue discharge trough 42 through the action of centrifugal force, thus preventing the water residue from accumulating on the filter screen plate 32 and causing the filter screen plate 32 to become clogged.
[0035] When this patent is working, the external sludge-water mixture is discharged into the cylinder 1 through the water inlet pipe 5. When the sludge-water mixture comes into contact with the filter screen plate 32, the water will pass through the filter screen plate 32 and fall into the cylinder 1, and then be discharged through the drain pipe 6. The water and sludge will be blocked by the filter screen plate 32. At the same time, the submersible motor 10 can drive the fixed frame 31 to rotate, so that the water and sludge on the filter screen plate 32 can be thrown out from the sludge discharge trough 42 and enter the collection sleeve 41 through the action of centrifugal force.
[0036] The water sludge entering the collection sleeve 41 will fall above the annular filter screen 433. The water droplets attached to the water sludge will pass through the annular filter screen 433 and fall into the empty trough 432. Then, it will be discharged into the drain pipe 6 through the water outlet pipe 7 in the empty trough 432, thus completing the secondary filtration of the water sludge.
