Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a gas field wastewater treatment device. Background Technology

[0002] An oil and gas field refers to the sum of oil reservoirs, gas reservoirs, and oil and gas reservoirs within the same area controlled by a single local structural unit. If the local structural area contains only oil reservoirs, it is called an oil field; if it contains only gas reservoirs, it is called a gas field. During the development of oil and gas fields, especially during the construction of gas and oil wells, a large amount of wastewater is generated. Direct discharge of this wastewater will cause environmental pollution, therefore, it is necessary to treat this wastewater.

[0003] Existing technologies disclose devices for treating this type of wastewater. For example, patent CN221544365U discloses a biological treatment device for oil and gas field wastewater. This device connects an inlet pipe to a separation pipe at its upper end, and a filter screen is fixed at the connection point between the inlet pipe and the separation pipe near the treatment tank. Simultaneously, an auger with through holes is installed inside the separation pipe, connected to a rotating motor via a gear set and a connecting rod. In operation, wastewater enters through the inlet pipe, and impurities in the wastewater are intercepted by the filter screen at the connection point between the inlet pipe and the separation pipe. The rotating motor drives a stirring paddle to rotate, which in turn drives the auger via the gear set and connecting rod. The auger transports the impurities to a discharge pipe at the upper end of the separation pipe, where they are collected in a collection tank. This solves the problem of ineffective removal of impurities from wastewater and improves the wastewater treatment efficiency.

[0004] Undeniably, the biological treatment device for oil and gas field wastewater disclosed in this patent can indeed achieve the above-mentioned effects, but it still has some shortcomings: the filter screen at the connection between the inlet pipe and the separation pipe is located inside the device, and it is difficult to clean when the filter screen is clogged, which will affect the wastewater inlet efficiency; in addition, the auger and the agitator are linked by a gear set and share the same rotating motor. Although this saves the number of motors, it also means that the auger and the agitator always rotate synchronously, regardless of whether the auger or the agitator needs to rotate, resulting in unnecessary energy consumption.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a gas field wastewater treatment device to solve the problems existing in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A gas field wastewater treatment device, comprising:

[0009] Treatment pool;

[0010] A filter tank fixed to the top front end of the treatment tank and connected to the treatment tank at the bottom;

[0011] The filter assembly installed in the filter tank includes a filter bucket with its front end hinged to the top of the front end of the filter tank, a filter stirring motor fixed in the middle of the filter bucket with its output shaft pointing vertically downward, a filter stirring shaft fixed to the bottom end of the output shaft of the filter stirring motor via a coupling, and a stirring plate fixed on the filter stirring shaft.

[0012] A support frame is fixed to the front end of the filter tank, and a winch is fixed to the top of the support frame; a pulley block is fixed to the middle position of the inner side of the top of the support frame; the wire rope on the winch passes through the pulley block and is fixedly connected to the middle position of the top of the rear end of the filter bucket.

[0013] Furthermore, the gas field wastewater treatment device also includes a chemical stirring assembly installed in the treatment tank; the chemical stirring assembly includes a fixed frame fixed at the middle position of the top of the treatment tank, a chemical stirring motor fixed at the middle position of the top of the fixed frame with its output shaft pointing vertically downward, a chemical stirring shaft fixed to the bottom end of the output shaft of the chemical stirring motor via a coupling, and a stirring rod in the shape of the number "7" fixed on the chemical stirring shaft.

[0014] Furthermore, the bottom of the filter pool slopes downwards at the end closest to the treatment pool.

[0015] Furthermore, the filter bucket has evenly spaced filter holes; the top, sides, and rear end of the filter bucket are integrally formed with flanges; a support rod is fixed to the top of the filter tank; when the filter bucket is placed in the filter tank, the flanges on both sides of the filter bucket abut against the top of the sides of the filter tank, and the flange at the rear end of the filter bucket abuts against the top of the support rod; and the rear end sidewall of the filter bucket is arc-shaped; when the filter bucket is flipped, the rear end of the filter bucket will not interfere with the support rod.

[0016] Furthermore, a fixing plate is fixed at the top front end of the filter bucket, and hinge cylinders are fixed at both ends of the bottom of the fixing plate; a slot is opened at the top front end of the filter pool, and the hinge cylinder is placed in the slot; hinge holes corresponding to the hinge cylinder are opened on the outer wall of the filter pool on both sides of the slot, and flange bearings are fixed in the hinge holes. The front end of the filter bucket is hinged to the top front end of the filter pool by means of a hinge rod passing through the flange bearing and the hinge cylinder.

[0017] Furthermore, two limiting blocks are symmetrically fixed on the front side wall of the filter pool below the slot, with the top of the limiting blocks inclined downward on the side closest to the filter pool.

[0018] Furthermore, the pulley block includes a pulley frame and two pulleys installed at the inner end of the pulley frame and distributed vertically; a fixing ring is fixed at the middle position of the top of the rear end of the filter bucket; the wire rope on the winch passes through the middle of the two pulleys and is fixed on the fixing ring.

[0019] Furthermore, an upwardly inclined guide plate is fixed to the top of the front end of the filter bucket.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The front end of the filter bucket of this utility model is hinged to the top of the filter tank, and the rear end is connected to the wire rope of the winch. The filter bucket is turned over by the winch. The filtered impurities are retained in the filter bucket. After turning over, they can be poured out and collected for centralized treatment. At the same time, it is easy to clean the internal residue of the filter bucket. In addition, a limiting block is set at the front end of the filter tank. When the filter bucket is turned over to a certain angle, the fixing plate abuts against the top of the limiting block to prevent the filter bucket from turning over too much.

[0022] (2) The filter bucket of this utility model is equipped with a filter stirring motor. The filter stirring motor drives the filter stirring shaft and stirring plate to rotate. The rotation of the stirring plate can prevent particulate matter from accumulating in the filter bucket, ensuring continuous and smooth filtration of sewage, improving filtration efficiency, and preventing the filtration speed from decreasing due to the deposition of particulate matter.

[0023] (3) The filter bucket of this utility model is provided with flanges on both sides of the top and the rear end. When reset, the flanges abut against the top of the filter tank and the top of the support rod. The flanges and the support rod form a stable support structure to prevent the filter bucket from shaking during the filtration process. In addition, the rear end side wall of the filter bucket is arc-shaped to ensure smooth flipping of the filter bucket and prevent mechanical interference between the filter bucket and the support rod.

[0024] (4) The bottom of the filter tank of this utility model is inclined to one end of the treatment tank. In this way, the filtered sewage is quickly flowed into the treatment tank by gravity, reducing the residence time of sewage in the filter tank and eliminating the need for additional power to guide the flow.

[0025] (5) The filter stirring motor and the reagent stirring motor of this utility model are set independently, and the operation of the filter stirring motor and the reagent stirring motor can be controlled separately according to the processing flow, avoiding unnecessary energy consumption caused by synchronous rotation in the prior art.

[0026] (6) The stirring rod in the shape of the number "7" is fixed on the stirring shaft of this utility model. When the stirring rod rotates, it can generate radial and axial water flow at the same time, forming a three-dimensional stirring effect, which helps to improve the treatment effect of sewage.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0045] Example

[0046] See appendix Figure 1-9 A gas field wastewater treatment device, comprising:

[0047] Processing pool 1;

[0048] A filter tank 2 is fixed to the top front end of the treatment tank 1 and its bottom is connected to the treatment tank; the bottom of the filter tank 2 is inclined downward at the end near the treatment tank 1.

[0049] The filter assembly 3 installed in the filter tank 2 includes a filter bucket 31 with its front end hinged to the top of the front end of the filter tank 2, a filter stirring motor 32 fixed at the middle position of the top of the filter bucket 31 with its output shaft pointing vertically downward (as can be clearly seen from the attached figure, a fixing rod 311 is fixed at the middle position of the top of the filter bucket 31, and the filter stirring motor 32 is fixed on the fixing rod 311), a filter stirring shaft 33 fixed to the bottom end of the output shaft of the filter stirring motor 32 via a coupling, and a stirring plate 34 fixed on the filter stirring shaft 33.

[0050] A support frame 4 is fixed to the front end of the filter tank 2, and a winch 5 is fixed to the top of the support frame 4; a pulley block 6 is fixed to the middle position of the inner side of the top of the support frame 4; the wire rope (not shown in the attached figure) on the winch 5 passes through the pulley block 6 and is fixedly connected to the middle position of the top of the rear end of the filter bucket 31; wherein, the pulley block 6 includes a pulley frame 61 and two pulleys 62 installed on the inner end of the pulley frame 61 and distributed vertically; a fixing ring 312 is fixed to the middle position of the top of the rear end of the filter bucket 31; the wire rope on the winch 5 passes through the middle of the two pulleys 62 and is fixed to the fixing ring 312;

[0051] The reagent stirring assembly 7 installed in the treatment tank 1 includes a fixed frame 71 fixed at the top center of the treatment tank 1, a reagent stirring motor 72 fixed at the top center of the fixed frame 71 with its output shaft pointing vertically downward, a reagent stirring shaft 73 fixed to the bottom of the output shaft of the reagent stirring motor 72 by a coupling, and a stirring rod 74 in the shape of the number "7" fixed on the reagent stirring shaft 73.

[0052] In this embodiment, filter holes 313 are evenly distributed on the filter bucket 31; flanges 314 are integrally formed on the top two sides and rear end of the filter bucket 31; a support rod 21 is also fixed on the top of the filter tank 2. When the filter bucket 31 is placed in the filter tank 2, the flanges 314 on both sides of the filter bucket 31 abut against the top of both sides of the filter tank 2, and the flange 314 at the rear end of the filter bucket 31 abuts against the top of the support rod 21; and the rear end side wall of the filter bucket 31 is arc-shaped; when the filter bucket 31 is flipped, the rear end of the filter bucket 31 will not interfere with the support rod 21.

[0053] In addition, in this embodiment, a fixing plate 315 is fixed at the top front end of the filter bucket 31, and hinge cylinders 316 are fixed at both ends of the bottom of the fixing plate 315; a slot 22 is opened at the top front end of the filter pool 2, and the hinge cylinder 316 is placed in the slot 22; hinge holes 23 corresponding to the hinge cylinder 316 are opened on the outer wall of the filter pool 2 on both sides of the slot 22, and flange bearings 24 are fixed in the hinge holes 23. The front end of the filter bucket 31 is hinged to the top front end of the filter pool 2 by means of a hinge rod 25 passing through the flange bearing 24 and the hinge cylinder 316.

[0054] Secondly, in this embodiment, two limiting blocks 26 are symmetrically fixed at the position of the front side wall of the filter pool 2 below the slot 22, and the top of the limiting blocks 26 is inclined downward on the side close to the filter pool 2; an upwardly inclined guide plate 317 is fixed at the top of the front end of the filter bucket 31.

[0055] Finally, in this embodiment, a drain pipe 11 is connected to the bottom of the treatment tank 1, and a valve 12 is connected to the end of the drain pipe 11.

[0056] During operation, the oilfield wastewater discharge pipe is placed at the filter tank 2, discharging wastewater into the filter bucket 31. During wastewater discharge, the filter stirring motor 32 is activated, driving the filter stirring shaft 33 and stirring plate 34 to rotate. The stirring action of the stirring plate 34 agitates the liquid in the filter bucket 31, preventing large particles from settling or accumulating inside and affecting the wastewater's passage through the filter bucket 31 into the filter tank 2. As the wastewater passes through the filter bucket 31 into the filter tank 2, the particulate matter carried in the wastewater is filtered by the filter bucket 31 and retained within it.

[0057] After the wastewater filtration is completed, the winch 5 is started. The wire rope of the winch 5 pulls the inner end of the filter bucket 31 upward, causing the filter bucket 31 to rotate around the hinge rod 25 as its axis. During the rotation of the filter bucket 31, particulate matter inside the filter bucket 31 falls out from the front end of the filter bucket 31. This filtered material can be collected by placing a container at the corresponding location on the ground for subsequent centralized processing. To prevent the filter bucket 31 from rotating too much, after the filter bucket 31 has rotated to a certain angle, the front end fixing plate 315 of the filter bucket 31 abuts against the top of the limit stop 26, preventing the filter bucket 31 from rotating. Of course, in actual operation, the operator will constantly observe the rotation angle of the filter bucket 31, and will stop the winch 5 when it approaches the limit stop 26. The limit stop 26 is set to prevent the filter bucket 31 from continuing to rotate during the process of cleaning the material inside the filter bucket 31 after the winch 5 has stopped. After the material filtered by the filter bucket 31 is cleaned, the winch 5 reverses and the filter bucket 31 returns to its original position. The flanges 314 on both sides of the filter bucket 31 abut against the top of both sides of the filter tank 2, and the flange 314 at the rear end of the filter bucket 31 abuts against the top of the support rod 21.

[0058] Wastewater passing through filter hopper 31 enters filter tank 2 and then flows into treatment tank 1. An appropriate amount of wastewater treatment agent is added to wastewater tank 1, and simultaneously, the agent stirring motor 72 is started. The agent stirring motor 72 drives the agent stirring shaft 73 and stirring rod 74 to rotate. The rotation of the stirring rod 74 mixes the agent and wastewater, improving the wastewater treatment effect.

[0059] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
