Description

Technical Field

[0001] The utility model belongs to the technical field of restaurant wastewater treatment, and particularly relates to a slag remover with a device for slowing down water flow speed. Background Art

[0002] The applicant's previous patent application number 202020175178.9 proposed a chain plate slag removal device with selectable inlet and outlet.

[0003] The patent mentions that a water-blocking baffle is hinged at the left water inlet or the right water inlet. When one of the left water inlet or the right water inlet serves as the water inlet end of the slag removal device, if the water inlet volume is large, the water-blocking baffle can be flushed up, rotated around the hinge point, and opened to a certain angle, effectively slowing down the water flow rate.

[0004] However, subsequent research found that this type of water-blocking baffle cannot control the flow direction of sewage, which can easily cause sewage to leak irregularly inside the chain-plate slag removal device. Utility Model Content

[0005] The utility model discloses a device for slowing down water flow speed, which is used for limiting the flow of a water inlet pipe.

[0006] The utility model discloses a slag remover with a water flow speed slowing device, comprising a box body, two water inlets, two water outlets and a chain plate type transmission assembly, wherein a water inlet pipe is fixed at each of the two water inlets; a slow flow device is provided at one end of the water inlet pipe extending into the box body;

[0007] Flow control devices include:

[0008] The sealing plate is fixedly connected to the end of the water inlet pipe extending into the box body, and the sealing plate seals the end of the water inlet pipe extending into the box body;

[0009] A side port is provided on the circumferential side wall of the water inlet pipe;

[0010] The water outlet baffle is adapted to the shape of the side outlet and is hinged at the side outlet. It can seal the side outlet by its own gravity and can be lifted up by the water flow in the water inlet pipe.

[0011] The two guide plates are welded on the circumferential side walls of the water inlet pipe. The axis of the water inlet pipe is arranged along the X direction, and the two guide plates are respectively located on both sides of the water outlet baffle along the X direction.

[0012] Furthermore, counterweights of different weights can be assembled on the outer wall of the water outlet baffle by means of bolts.

[0013] Because catering venues are different, the instantaneous amount of water flow in the water inlet pipe is different in actual situations. Therefore, it is necessary to increase the overall weight of the water outlet baffle and the counterweight by welding, to suppress the impact of the larger instantaneous water inflow on the water outlet baffle, and to ensure that the angle at which the water outlet baffle is lifted is always within a reasonable range. The weight of the welded counterweight is different in different actual usage situations.

[0014] Furthermore, observing from a top view, one end of the guide plate perpendicular to the X direction is marked as end A, and the other end is marked as end B; assuming that end A of the guide plate is flush with the hinge axis of the water outlet baffle, the distance between end A and end B of the guide plate is D, and D is greater than the diameter of the water inlet pipe.

[0015] The reason why the distance D between ends A and B is greater than the diameter of the water inlet pipe is because the shape of the water outlet baffle is an arc. When the water outlet baffle blocks the side port, it can just be assembled into the water inlet pipe. When the water outlet baffle is lifted up, the water flow in the original water inlet pipe will move along the trajectory of the inner wall shape of the water outlet baffle, that is, the arc shape. The water outlet baffle has a guiding effect on the water flow. If D is less than or equal to the diameter of the water inlet pipe, when the water flow leaves the water outlet baffle, the guide plate will not be able to continue to guide the water flow, and the water will still flow in all directions. This arrangement of the present invention ensures that the length of the guide plate is sufficient, so that the water flow can continue to be guided by the guide plate after leaving the water outlet baffle, thus preventing water from flowing in all directions.

[0016] Furthermore, when viewed in the X direction, the side opening is in the shape of an arc, and the central angle of the arc is less than 180 degrees.

[0017] From a top view, after the water in the original water inlet pipe flows out from the side port, the flow trajectory is to move from end A to end B of the guide plate. If the central angle of the arc is greater than 180 degrees, the water flow may be guided by the inner wall of the water outlet baffle and move downward again when moving along the inner wall of the water outlet baffle. From a top view, the purpose of moving from end A to end B of the guide plate cannot be achieved, and the fundamental purpose will not be realized.

[0018] Furthermore, the axis of the hinge shaft of the water outlet baffle is parallel to the X direction.

[0019] Control the direction of the water flow out of the side port so that the water flow can move along the inner wall trajectory of the water outlet baffle, and make the water flow trajectory as parallel as possible to the direction guided by the guide plate. If it is not parallel to the X direction, the water flow will hit the guide plate on one side after leaving the water outlet baffle, causing water to easily leak. Beneficial effects

[0020] This solution utilizes an upward-lifting outlet baffle, allowing the water to flow along its inner wall. Two guide plates are also provided to guide the water that leaves the outlet baffle, ultimately landing on the chain plates of the chain conveyor assembly. This prevents water from scattering.

[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0028] See Figure 1 and Figure 2 A slag remover with a water flow slowing device comprises a housing 1, within which are mounted three sets of sprockets 2. Each set of two sprockets 2 is connected to the inner wall of the housing 1 via a rotating shaft. A ring-shaped chain is wound around each sprocket 2, and a chain plate is provided on the chain. The chain plate comprises a plurality of chain plate units with equal pitch, each having a plurality of filter holes. A motor is mounted outside the housing 1, with the motor's output shaft fixedly connected to the rotating shaft of one set of sprockets 2.

[0029] The box 1 below the chain plate is divided into two parts: a slag storage tank 4 and a first water storage tank 3. The chain plate is tilted, with the higher end located directly above the slag storage tank 4. The two side walls of the box 1 are designated as the left and right panels. The left panel has a left water inlet and a left water outlet. The right panel has a right water inlet and a right water outlet. The left and right water inlets are located on the side panels above the chain plate, while the left and right water outlets are located on the side panels corresponding to the first water storage tank 3.

[0030] The pore size of the filter holes can be determined according to design requirements, so that debris with smaller and larger diameters can be effectively filtered. When the catering wastewater flows into the box 1 through the left water inlet or the right water inlet, the wastewater first falls onto the chain plate. Because there are dense filter holes on the chain plate, the oily wastewater can enter the first water storage tank 3 through the filter holes on the chain plate, and the debris larger than the pore size of the filter holes is filtered on the chain plate.

[0031] The motor starts and drives the sprocket 2 to rotate, thereby driving the entire chain plate to move from the lower end to the higher end. The filtered slag is transported along the chain plate to the top of the slag storage pool 4, falls into the slag storage pool 4 under the action of gravity, and is discharged from the slag outlet.

[0032] When installing the slag removal device, the required water inlet and water outlet are selected according to the needs, and the unnecessary water inlet and water outlet are sealed with the blind plate 11.

[0033] The box 1 is equipped with a partition 5, with a brush attached to its lower end, which contacts the upper surface of the chain plate. Both sides of the partition 5 are sealed and fixed to the inner walls of the corresponding side panels of the box 1. The partition 5 is located above the lower end of the chain plate. The chain plate, partition 5, left side panel, and right side panel form a second water reservoir. A water level sensor is installed in this second water reservoir. The partition 5 is provided with an overflow port, located above the first water reservoir 3.

[0034] If dirt blocks the holes in the chain, preventing the oily wastewater from being filtered and drained away, it is temporarily stored in the second water tank. When the wastewater in the partition 5 rises to the water level sensor, the motor starts, driving the sprocket 2 to rotate, thereby moving the entire chain from the lower end to the higher end. The corresponding portion of the chain unblocked by the holes rotates, temporarily accelerating the chain's filtration capacity. If the water level sensor is damaged or the motor starts, the wastewater still cannot be effectively drained away in a timely manner, the liquid level continues to rise, then flows out through the overflow port and into the first water tank 3.

[0035] The above are all existing technologies and are not the design of this embodiment.

[0036] The design of this embodiment is that water inlet pipes 6 are fixedly installed at the left water inlet and the right water inlet. In this embodiment, the water inlet pipes 6 are horizontally arranged, and the water inlet pipes 6 are circular pipes. The two water inlet pipes 6 are provided with a slow flow device at one end extending into the box body 1. The slow flow device can slow down the flow rate of the oily wastewater entering the slag removal device, and the slow flow device can also prevent the oily wastewater from irregularly flowing around the slag removal device.

[0037] Because the slag removal device only uses the left water inlet or the right water inlet each time, and the unused water inlet is sealed with a blind plate 11 , the water inlet pipe 6 at one of the left water inlet or the right water inlet is also sealed with a blind plate 11 .

[0038] See Figure 3 、 Figure 4 and Figure 5 , the slow flow device includes:

[0039] The sealing plate 7 is fixedly connected to one end of the water inlet pipe 6 extending into the box body 1, and the sealing plate 7 is used to block the original pipe opening of the water inlet pipe 6.

[0040] Side port 8 is formed on the circumferential sidewall of the water inlet pipe 6 and is located within the housing 1. Side port 8 serves as a new pipe opening for allowing the oily wastewater flowing into the water inlet pipe 6 to flow into the housing 1. As viewed along the axis of the water inlet pipe 6, side port 8 is formed at the upper end of the water inlet pipe 6. In this embodiment, as viewed along the axis of the water inlet pipe 6, side port 8 is arc-shaped. In this embodiment, as viewed along the axis of the water inlet pipe 6, side port 8 is arc-shaped, with a central angle of less than 180 degrees.

[0041] The outlet baffle 9, adapted to the shape of the side opening 8, is hingedly connected to the side opening 8. Its hinge 12 is mounted on the circumferential sidewall of the water inlet pipe 6, with the axis of the hinge 12 parallel to the axis of the water inlet pipe 6. When the outlet baffle 9 is subjected only to its own weight, it tightly seals the side opening 8. When the water flow in the water inlet pipe 6 is high, the oily wastewater will push up the outlet baffle 9, causing it to rotate about the hinge 12. This rotation exposes a portion of the side opening 8, and the oily wastewater enters the housing 1 through the exposed portion of the side opening 8. During design, the weight of the outlet baffle 9 should be considered based on the actual water flow in the water inlet pipe 6. If the weight of the water outlet baffle 9 is too great, the oily wastewater in the water inlet pipe 6 will not be able to lift the water outlet baffle 9; if the weight of the water outlet baffle 9 is too light, the rotation angle of the water outlet baffle 9 will exceed 90 degrees, resulting in the water outlet baffle 9 being unable to fall back under its own weight to cover the side opening 8 after turning over. Therefore, this solution assembles counterweights of different weights on the outer wall of the water outlet baffle 9 through bolts according to actual usage conditions. This ensures that when the water outlet baffle 9 is impacted by the oily wastewater, the rotation angle of the water outlet baffle 9 is less than 60 degrees. The rotation angle of the water outlet baffle 9 is less than 60 degrees, which ensures that the water outlet baffle 9 can naturally fall back under its own weight to cover the side opening 8.

[0042] Two guide plates 10 are welded to the circumferential outer wall of the water inlet pipe 6. The axial direction of the water inlet pipe 6 is set along the X direction. The two guide plates 10 are respectively set on both sides of the water outlet baffle 9 along the X direction. The two guide plates 10 extend a certain height along the radial direction of the water inlet pipe 6 in the direction away from the axis of the water inlet pipe 6. The maximum height of the extended height from the side wall of the water inlet pipe 6 is set to H. When the guide plate 10 is rotated to 60 degrees, the maximum height between the end of the guide plate 10 away from the hinge axis and the water inlet pipe 6 is G, as viewed from the axial direction of the water inlet pipe 6. Then H is greater than G. This is to ensure that when the wastewater leaves the water outlet baffle 9 from the non-hinge end of the water outlet baffle 9, it can continue to be guided by the guide plate 10. The guidance here means that in the X direction, the wastewater is also restricted by the guide plate 10, and the wastewater cannot bypass the guide plate 10 and run away in the X direction. Figure 3 , along the top view, one end of the guide plate 10 perpendicular to the X direction is end A, and the other end is end B. End A of the guide plate 10 is flush with the hinge axis. The distance between end A and end B of the guide plate 10 is D, and D is greater than the diameter of the water inlet pipe 6. This is to enable the guide plate 10 to guide the wastewater along the radial direction of the water inlet pipe 6.

[0043] The use process of this slow flow device

[0044] When the instantaneous flow of the oily wastewater entering the water inlet pipe 6 is large, the outlet baffle 9 is lifted up by the oily wastewater, and the outlet baffle 9 rotates to expose part of the side port 8, and the oily wastewater is sprayed out from the side port 8.

[0045] Since the inner wall of the outlet baffle 9 is arc-shaped, the movement trajectory of the oily wastewater along the axis of the water inlet pipe 6 can be approximately regarded as an arc along the inner wall of the outlet baffle 9. Figure 3 It can be seen that the movement trajectory of the oily wastewater moves from end A to end B of the guide plate 10.

[0046] Limited by the two guide plates 10, the oily wastewater cannot move along the axis of the water inlet pipe 6, and Figure 3 As you can see, the wastewater also moves from the A end to the B end of the guide plate 10, and is converted into Figure 1 From a visual perspective, wastewater flows from the lower end to the upper end of the chain plate; in the actual deslagging device, the distance between the lower and upper ends of the chain plate is long, ensuring that the oily wastewater ejected from the side port 8 falls on the chain plate. If there were no guide plate 10, and the guide plate 10 did not restrict the wastewater in the X direction, the oily wastewater might splash in the X direction. This would cause the oily wastewater to hit the inner wall of the deslagging device in the X direction, further causing the oily wastewater to splash everywhere, that is, the water would be scattered in all directions.

[0047] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
