Description

Technical Field

[0001] This utility model belongs to the field of surface floating scum collection devices for rectangular sedimentation tanks, specifically relating to a gravity-type self-flowing oil and scum discharge trough device. Background Technology

[0002] Sedimentation tanks are structures that remove suspended solids from water using sedimentation, thus purifying the water. They utilize natural sedimentation or coagulation to remove suspended solids. Sedimentation tanks are classified into horizontal and vertical sedimentation tanks based on the direction of water flow. The sedimentation effect depends on the water flow velocity and residence time in the tank. To improve sedimentation efficiency and reduce land area, honeycomb inclined tube countercurrent flow sedimentation tanks, accelerated clarification tanks, and pulse clarification tanks are commonly used. During daily operation, due to factors such as algae in the raw water, excessive chemical dosage, and dust pollution in the air, chemical residues, dust, or foam often float on the water surface, affecting equipment operation and aesthetics, and in severe cases, potentially impacting the quality of the effluent.

[0003] Currently, the technology for collecting surface scum in rectangular sedimentation tanks has matured, forming a pattern dominated by mechanical methods but supplemented by other technologies. Its core objective is to efficiently, automatically, and reliably remove surface scum to ensure effluent quality and improve the plant environment. Existing mainstream equipment types include chain scraper skimmers, traveling skimmers, rotary skimmers, and non-powered floating collection tanks.

[0004] The existing new sedimentation tanks use a new type of scum collection device with a new structure, which is compatible with the structure of the new sedimentation tank. However, for old rectangular sedimentation tanks, the existing new structure of scum collection device is not compatible with the traditional old rectangular sedimentation tank. The existing mainstream equipment cannot fully cover the surface of the old rectangular sedimentation tank, and it cannot effectively collect the scum in the old rectangular sedimentation tank, resulting in poor collection effect and low collection efficiency. Utility Model Content

[0005] In response to the problems mentioned in the background art, this utility model proposes a gravity-type self-flowing oil and slag discharge trough device. Based on the old rectangular sedimentation tank, a new slag collection device is designed, which is better adapted to the original sedimentation tank structure. At the same time, the equipment has a simple structure, low maintenance cost, and good collection effect.

[0006] Technical solution: To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A gravity-fed oil and slag discharge trough device includes a collection trough, a gravity rotating mechanism, and a sealing baffle. The collection trough is placed inside a sedimentation tank, and the sealing baffle is attached to the inner wall of the collection trough. The sealing baffle is equipped with multiple gravity rotating mechanisms. The gravity rotating mechanism controls the sealing baffle to move away from the collection trough, thereby guiding the scum on the surface of the sedimentation tank into the collection trough and discharging it through the discharge port. Finally, after the scum is cleaned, the sealing baffle is reattached to the collection trough.

[0008] Preferably, multiple evenly distributed inlets are provided on the upper side of one side of the collection tank.

[0009] Preferably, a slag discharge trough is provided on the side adjacent to the inlet end of the collection trough. The slag discharge trough is connected to the collection trough and has a discharge port to discharge the floating slag in the collection trough.

[0022] The present invention will be further illustrated below with reference to specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0023] The gravity-type self-flowing oil and sludge discharge trough device provided in this embodiment is used to collect floating oil and sludge on the surface of an old rectangular sedimentation tank 1. The main structure includes a collection trough 2, a gravity rotating mechanism 4, and a sealing baffle 3. The collection trough 2 is fixed on the sedimentation tank 1, and the two sides of the collection trough 2 are connected to the two sides of the interior of the sedimentation tank 1. The sealing baffle 3 is attached to the inner wall of the collection trough 2, and the gravity rotating mechanism 4 is provided on the side end of the sealing baffle 3. The gravity rotating mechanism 4 controls the sealing baffle 3 to move away from the collection trough 2, thereby using the difference between high and low water levels to allow the sludge on the surface of the sedimentation tank 1 to flow into the collection trough 2 through the inlet 21 provided on the collection trough 2, and to be discharged through the outlet 5 on the side end. Finally, after the sludge is cleaned up, the sealing baffle 3 is reattached to the collection trough 2.

[0024] like Figures 1-2 As shown, the collection tank 2 is rectangular, and multiple inlets 21 for water and scum to enter are provided on the upper side of one side of the collection tank 2. The inlets 21 are rectangular and are evenly spaced on the collection tank 2.

[0025] In this embodiment, the width of the collection trough 2 is 190mm and the height is 330mm.

[0026] In this embodiment, the rectangular inlet 21 has a length of 500mm and a height of 80mm.

[0027] A slag discharge trough 22 is provided on the side adjacent to the inlet 21 end of the collection trough 2. The collection trough 2 is connected to the slag discharge trough 22. The slag discharge trough 22 is provided with a discharge port 5. The floating slag in the collection trough 2 is discharged by opening the discharge port 5.

[0028] The slag discharge trough 22 is also part of the sedimentation tank 1, but it is not connected to the sedimentation tank 1. It is a separate slag discharge channel, and the discharge port 5 is set on the slag discharge trough 22.

[0029] In this embodiment, the collection tank 2 is made of stainless steel 304.

[0030] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, the sealing baffle 3 is rectangular and includes a first baffle 31, a second baffle 32 and a third baffle 33 in sequence; the first baffle 31, the second baffle 32 and the third baffle 33 are fixed together by bolts.

[0031] The size of the first baffle 31 is the same as the size of the notch on the collection tank 2, i.e., the inlet 21. The sealing baffle 3 is tightly fitted to the inner wall of the collection tank 2 by the counterweight rotation mechanism 4, realizing the opening and closing of the inlet 21. When the inlet 21 is blocked, the first baffle 31 is engaged with the inlet 21 to seal it tightly. The structure is reasonable and the sealing effect is good.

[0032] The top height of the second baffle 32 is the same as the top height of the collection tank 2, and it is used to assist the first baffle 31 and enhance its sealing effect.

[0033] The top height of the third baffle 33 is higher than that of the top height of the first baffle 31 and the second baffle 32, which is used to enhance its sealing effect and facilitates connection with the counterweight rotation mechanism 4.

[0034] In this embodiment, the length of the sealing baffle 3 is the same as the length of the collection tank 2. The sealing baffle 3 is made of both stainless steel 304 and rubber gasket. In this embodiment, a sealing strip is provided at the connection end between the first baffle 31 and the inlet 21 of the collection tank 2. The sealing strip can be made of rubber gasket material to improve the sealing effect.

[0035] In this embodiment, the width of the second baffle 32 is greater than the width of the first baffle 31 and the third baffle 33; the size of the first baffle is 500mm*80mm, the size of the second baffle is 3347mm*120mm, and the size of the third baffle is 3347mm*200mm.

[0036] In this embodiment, the third baffle 33 is welded to the counterweight rotation mechanism 4, and the angles of its equipment connecting parts are fixed.

[0037] like Figure 4 , Figure 5 As shown, the counterweight rotation mechanism 4 includes a baffle connecting plate 41, a rotating support 42, a rotation limit block 43, a counterweight connecting rod 44, and a counterweight 45.

[0038] The rotating support 42 has a U-shaped side and there are two of them. The two rotating supports 42 are located above the collection tank 2 and are fixedly installed on both sides of the sedimentation tank 1. A circular shaft 7 is provided between the two rotating supports 42 and is located at the center of the rotating support 42. The counterweight connecting rod 44 is connected to the circular shaft 7 of the rotating support 42 to realize rotation around the circular shaft 7. One end of the baffle connecting plate 41 is fixedly connected to the third baffle 33, and the other end is connected to the counterweight connecting rod 44. A rotation limit block 43 is provided at the lower end of the circular shaft 7. A counterweight 45 is provided on the counterweight connecting rod 44.

[0039] By manually pulling the weight connecting rod 44, it rotates around the circular axis 7 of the rotating support 42, thereby driving the baffle connecting plate 41 and the sealing baffle 3 to rotate.

[0040] The collection tank 2 is in a sealed state. When it is necessary to open the collection tank 2, first manually pull the weight connecting rod 44 so that it rotates in the opposite direction around the circular axis 7 of the rotating support 42 by a certain angle (45° in this embodiment). As the weight connecting rod 44 rotates, it drives the baffle connecting plate 41 and the sealing baffle 3 to rotate (the direction of rotation of the baffle connecting plate 41 and the sealing baffle 3 is the same as that of the weight connecting rod 44). When the weight connecting rod 44 slowly rotates to the direction close to the inlet 21 on the collection tank 2, the sealing baffle 3 also rotates synchronously, moving away from the collection tank 2 and close to the rotating limit block 43 until it contacts one end face (blocking end) of the rotating limit block 43. At the instant when the sealing baffle 3 separates from the collection tank 2, and when the water level in the sedimentation tank 1 and the inlet 21 of the collection tank 2 form a high-low difference, the water flow carries the scum accumulated on the liquid surface into the collection tank 2.

[0041] After all the scum on the surface of the liquid falls into the collection tank 2, when it is necessary to seal the inlet 21 on the collection tank 2, the counterweight connecting rod 44 is manually pulled in the opposite direction (in this embodiment, it can rotate 45 degrees) around the circular shaft 7, that is, the counterweight connecting rod 44 is away from the end of the inlet 21 on the collection tank 2, the baffle connecting plate 41 is away from the rotation limit block 43, and the sealing baffle 3 rotates with the counterweight connecting rod 44 and the baffle connecting plate 41, which locks and seals the inlet 21 on the collection tank 2, thus closing the collection tank 2.

[0042] Finally, the scum in the collection tank 2 can be discharged into the scum discharge tank 22 by opening the discharge port 5 for further treatment.

[0043] In this embodiment, the counterweight rotation mechanism 4 is made of stainless steel 304.

[0044] In this embodiment, there are three of each: baffle connecting plate 41, rotation limiting block 43, counterweight connecting rod 44, and counterweight 45. The three counterweight connecting rods 44 are connected by steel plate 8, which facilitates the control of the opening and closing of the inlet 21 on the collection tank 2 by the sealing baffle 3.

[0045] In this embodiment, the weight 45 uses gravity to counteract the pressure of water and scum in the sedimentation tank 1 on the sealing baffle 3, so that the first baffle 31 (sealing strip) on the sealing baffle 3 is tightly attached to the collection tank 2, which improves the sealing effect and makes the sealing effect good.

[0046] In this embodiment, a collection trough support 6 is provided at the lower end of the collection trough 2 for fixing the collection trough 2. A pre-embedded steel plate is reserved on the collection trough support 6, and the collection trough 2 is welded to the pre-embedded steel plate.

[0047] The working principle or usage process of this utility model is as follows: When workers inspect the site every day and see scum and oil floating on the surface of the sedimentation tank 1, they manually turn the counterweight rotation mechanism 4 to open the sealing baffle 3 on the collection tank 2. The scum and oil floating on the surface of the sedimentation tank 1 are carried into the collection tank 2 by the kinetic energy of the water flowing downhill, and flow into the slag discharge tank 22 through the discharge port 5 at the rear end of the collection tank 2. After the scum and oil floating on the surface of the sedimentation tank 1 are cleaned, the counterweight rotation mechanism 4 is turned again to make the sealing baffle 3 re-fit the collection tank 2.

[0048] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
