Abstract
Description
Technical Field
[0001] This utility model relates to the field of storage device technology, specifically to an oil-based rock cuttings dry residue storage bin. Background Technology
[0002] Oil-based rock cuttings are oil-containing solid wastes generated during oil and gas drilling. They are characterized by high viscosity and solid-liquid mixing. Their storage must take into account requirements such as leakage prevention, rapid discharge, and environmental protection.
[0003] However, traditional storage silos have the following significant drawbacks in practical applications: conventional silos mostly adopt a flat-bottom or fixed-angle design, relying solely on the material's own weight to slide down during discharge. High-viscosity dry slag easily accumulates at the bottom, requiring frequent manual cleaning, and the residue may contaminate the silo. The lack of a built-in solid-liquid separation structure leads to the mixed storage of liquids and solids, increasing subsequent processing costs and potentially causing environmental pollution due to leakage. Furthermore, existing silos have a fixed or limited angle of inclination, preventing large-angle tilting during discharge, resulting in slow discharge speed and low efficiency. Therefore, there is an urgent need to design a new oil-based rock cuttings dry slag storage silo to solve these problems. Utility Model Content
[0004] The purpose of this utility model is to provide an oil-based rock cuttings dry residue storage bin with the advantages of efficient discharge, solid-liquid pre-separation, strong dynamic stability and convenient operation. It solves the problems of serious discharge residue, difficulty in separating solid-liquid mixture, and low discharge efficiency caused by limited tilt angle adjustment in traditional storage bins.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an oil-based rock cuttings dry residue storage bin, including a storage bin, a limiting component fixedly installed at the bottom front end of the outer wall of the storage bin, a conical structure design at the bottom of the storage bin, a filter plate fixedly installed at the bottom inner side of the storage bin, and support frames rotatably installed on both sides of the storage bin.
[0006] The limiting component includes a base frame, on which an adjusting cylinder is fixedly installed. A connecting frame is fixedly installed on the top of the adjusting cylinder, and the connecting frame contacts the outer wall of the storage bin but is not fixedly connected.
[0007] Preferably, the storage bin has an inlet and outlet at the top rear end, a sealing cover is movably installed on the inlet and outlet, rotating shafts are fixedly installed on both sides of the storage bin, and a drain trough is opened at the bottom of the storage bin.
[0008] In the design, by setting inlet and outlet ports at the top rear end of the storage silo and installing a movable sealing cover, the convenience of two-way operation for loading and unloading is achieved. At the same time, the position of the inlet and outlet ports optimizes the gravity guidance during unloading.
[0009] Preferably, the bottom of the sealing cover is provided with a sealing block, the size of which matches the size of the inlet / outlet at the rear end of the top of the storage bin.
[0010] In the design, by setting a sealing block at the bottom of the sealing cover that matches the size of the inlet and outlet, the evaporation of oil and gas is effectively blocked and dust and moisture are prevented, thereby improving the safety and environmental friendliness of the storage environment.
[0011] Preferably, a flap valve is installed at the bottom of the drainage tank, and the flap valve is designed with a manual control structure.
[0012] In the design, a manual flap valve is connected to the bottom of the drainage tank to achieve liquid discharge control without power dependence, which is suitable for outdoor scenarios without electricity, while reducing the complexity of the equipment.
[0013] Preferably, there are two support frames, each with a hole and a bearing embedded in it, and the two support frames are rotatably mounted via bearings and a rotating shaft.
[0014] In the design, by embedding bearings in the support frame and rotating them with the shaft, low frictional resistance is achieved when the storage bin is flipped, ensuring smooth operation at large angles.
[0015] Preferably, the bottom of the base frame is on the same plane as the bottom of the two support frames, and the base frame is designed with H-shaped steel.
[0016] In the design, by making the bottom of the base frame and the support frame coplanar, the overall center of gravity of the equipment is stably distributed, preventing the risk of tipping over; by using H-beam steel for the base frame, the structural strength and deformation resistance under high load scenarios are achieved, extending the service life.
[0017] Preferably, the connecting frame is fixedly connected to the piston end of the adjusting cylinder by mounting screws.
[0018] In the design, by fixing the connecting bracket to the piston end of the adjusting cylinder with mounting screws, the limit component can be quickly disassembled and maintained, while ensuring the reliability of cylinder thrust transmission.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] This invention achieves efficient material discharge, solid-liquid pre-separation, strong dynamic stability, and convenient operation by setting a conical bottom structure, adjustable limiting components, and a filter plate.
[0021] Specifically, the conical bottom design of the storage silo guides the dry residue to concentrate at the discharge port. Combined with the active contraction of the regulating cylinder of the limiting component, the connecting frame is released from contact with the outer wall of the storage silo, allowing the storage silo to rotate at a large angle around the axis and use gravity to completely discharge the material. This solves the problem of serious material residue and the need for manual cleaning in traditional flat-bottom storage silos.
[0022] Solid particles are intercepted by a filter plate fixedly installed at the bottom of the inner side of the storage silo, and the liquid flows through the drain trough to the manual flap valve, realizing instant separation during storage. This solves the problems of difficult solid-liquid separation and high subsequent processing costs in traditional storage silos.
[0023] By extending the cylinder, the connecting frame is pressed tightly against the outer wall of the storage bin, forming a rigid limit; by retracting the cylinder, the limit is released, and the storage bin can be freely rotated. In conjunction with the bearing rotation structure of the support frame, the problems of low material discharge efficiency and the risk of tipping over are solved.
[0024] The manual flap valve controls the liquid discharge, and the pneumatic regulating cylinder releases the limit switch with one click. It does not require electric drive, adapts to complex field conditions, and solves the problems of traditional equipment relying on external power and complicated operation.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Example 1
[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of the present invention is provided: an oil-based rock cuttings dry residue storage bin, including a storage bin 1, a limiting component 3 fixedly installed at the bottom front end of the outer wall of the storage bin 1, a conical structure design at the bottom of the storage bin 1, a filter plate 14 fixedly installed at the bottom inner side of the storage bin 1, and support frames 12 rotatably installed on both sides of the storage bin 1.
[0033] The limiting component 3 includes a base frame 31, on which an adjusting cylinder 32 is fixedly installed. A connecting frame 33 is fixedly installed on the top of the adjusting cylinder 32. The connecting frame 33 contacts the outer wall of the storage bin 1 but is not fixedly connected.
[0034] Specifically, by setting a conical bottom structure, an adjustable limiting component 3, and a filter plate 14, the system achieves efficient material discharge, solid-liquid pre-separation, strong dynamic stability, and convenient operation.
[0035] Specifically, the conical bottom design of the storage bin 1 guides the dry residue to concentrate at the discharge port. Combined with the active contraction of the regulating cylinder 32 of the limiting component 3, the connecting frame 33 is released from contact with the outer wall of the storage bin 1, allowing the storage bin 1 to rotate around the rotating shaft 11 at a large angle and use gravity to completely discharge the material, thus solving the problem of serious material residue and the need for manual cleaning in traditional flat-bottom storage bins.
[0036] Solid particles are intercepted by the filter plate 14 fixedly installed at the bottom of the inner side of the storage bin 1, and the liquid flows to the manual flap valve 2 through the drain trough 15, realizing instant separation during storage. This solves the problems of difficult solid-liquid separation and high subsequent processing costs in traditional storage bins.
[0037] By extending the cylinder, the connecting frame 33 is pressed tightly against the outer wall of the storage bin 1, forming a rigid limit; by retracting the cylinder, the limit is released, and the storage bin 1 can be freely flipped. In conjunction with the bearing rotation structure of the support frame 12, the problems of low material discharge efficiency and the risk of tipping over are solved.
[0038] The manual flap valve 2 controls the liquid discharge and the pneumatic regulating cylinder 32 releases the limit with one key. It does not require electric drive, adapts to complex field conditions, and solves the problems of traditional equipment relying on external power and complicated operation.
[0039] Example 2
[0040] To achieve convenient bidirectional operation of the storage silo, solid-liquid separation, and large-angle tilting discharge function, such as Figure 1 and Figure 3As shown in this embodiment, the storage bin 1 has an inlet and outlet at the top rear end, a sealing cover 13 is movably installed on the inlet and outlet, a rotating shaft 11 is fixedly installed on both sides of the storage bin 1, and a drain trough 15 is opened at the bottom of the storage bin 1.
[0041] In the design, by setting inlet and outlet ports at the top rear end of storage bin 1 and movably installing sealing cover 13, the convenience of two-way operation for loading and unloading is realized, and the position of inlet and outlet ports optimizes gravity guidance during unloading.
[0042] Furthermore, a sealing block is provided at the bottom of the sealing cover 13, and the size of the sealing block matches the size of the inlet and outlet at the rear end of the top of the storage bin 1.
[0043] In the design, by setting a sealing block at the bottom of the sealing cover 13 that matches the size of the inlet and outlet, the effective blocking of oil and gas volatilization and dust and moisture prevention are achieved, thereby improving the safety and environmental friendliness of the storage environment.
[0044] Furthermore, a flap valve 2 is connected to the bottom of the drain tank 15, and the flap valve 2 adopts a manually controlled structure design.
[0045] In the design, by connecting the manual flap valve 2 to the bottom of the drain tank 15, liquid discharge control without power dependence is realized, which is suitable for outdoor scenarios without electricity, while reducing the complexity of the equipment.
[0046] Furthermore, there are two support frames 12, each with a hole and a bearing embedded in it. The two support frames 12 are rotatably mounted to the rotating shaft 11 via the bearings.
[0047] In the design, by embedding a bearing in the support frame 12 and rotating it with the shaft 11, low frictional resistance is achieved when the storage bin 1 is flipped, ensuring smooth operation of large-angle movements.
[0048] Example 3
[0049] In order to achieve overall equipment stability and rapid maintenance of the limiting components, in this embodiment, the bottom of the base frame 31 and the bottom of the two support frames 12 are on the same plane, and the base frame 31 is designed with H-shaped steel.
[0050] In the design, by making the bottom of the base frame 31 and the support frame 12 coplanar, the overall center of gravity of the equipment is stably distributed, preventing the risk of tipping over; by using H-beam steel for the base frame 31, the structural strength and deformation resistance under high load scenarios are achieved, extending the service life.
[0051] Furthermore, the connecting bracket 33 is fixedly connected to the piston end of the adjusting cylinder 32 by mounting screws.
[0052] In the design, by fixing the connecting bracket 33 to the piston end of the adjusting cylinder 32 with mounting screws, the quick disassembly and maintenance of the limit component 3 is realized, while ensuring the reliability of cylinder thrust transmission.
[0053] In use, the sealing cover 13 at the top rear end of the storage silo 1 is manually opened to expose the inlet and outlet. Oil-based rock cuttings and dry slag are poured into the storage silo 1 through the inlet and outlet; the material naturally slides to the bottom due to the conical bottom 1. The sealing cover 13 is then closed, and its bottom sealing block fits tightly against the inlet and outlet to prevent oil vapor evaporation and external contamination.
[0054] The material is left to stand in storage silo 1. The liquid seeps into the drain tank 15 through the bottom filter plate 14, while the solids are intercepted. The operator opens the manual flap valve 2 at the bottom of the drain tank 15 to discharge the separated liquid to the collection device.
[0055] The adjusting cylinder 32 of the start-stop component 3 retracts, causing the connecting frame 33 to move downwards, thus disengaging the connecting frame 33 from the outer wall of the storage bin 1 and releasing the front-end limit. With the front end of the storage bin 1 no longer constrained, it can rotate freely around the two side pivots 11, and the bearings of the support frame 12 ensure smooth rotation.
[0056] The storage bin 1 is rotated around the pivot 11 by manual or mechanical means. With the limit switch released, the storage bin can tilt to 90° or a greater angle. The conical bottom 1, combined with the large tilt angle, allows material to slide quickly out of the inlet and outlet under gravity, completely emptying the bin and preventing residue. If material adheres, gently tapping the bin wall or a brief vibration can accelerate discharge.
[0057] After discharge, push the storage bin 1 back to its initial position. Activate the adjusting cylinder 32 to extend, pushing the connecting frame 33 upwards and tightly against the outer wall of the storage bin, providing a new rigid limit. Confirm that the sealing block is completely fitted with the inlet and outlet after the sealing cover 13 is reset, ensuring storage airtightness.
[0058] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
