Description

TECHNICAL FIELD

[0001] The utility model relates to sewage sludge treatment technical field, concretely relates to a shale gas produced water sludge cake recovery device. BACKGROUND

[0002] In the shale gas exploitation process, the produced water contains a large amount of solid particles, chemical substances and other impurities. These impurities often form sludge cake after a series of treatment processes.

[0003] In order to avoid pollution to the environment, and realize the effective use of resources, the sludge cake needs to be properly treated and safely transported out. In the shale gas exploitation site, the formed sludge cake is usually transported by the second floor conveyor belt. The design of these conveyor belts is to efficiently transport the sludge cake from the production area to the loading point. The end of the conveyor belt is suspended from the second floor and the sludge cake is free-falling to the outdoor first floor after being formed on the conveyor belt.

[0004] The space below the end of the conveyor belt is usually reserved so that the truck for transferring the sludge cake can be parked there. When the truck is ready, the sludge cake can be directly dropped from the end of the conveyor belt into the truck's hopper, thereby greatly improving the transfer efficiency of the sludge cake. This design not only reduces the cost of manual handling, but also shortens the time from production to transportation of the sludge cake.

[0005] However, in actual use, this efficient transfer method faces some problems. Since the production time of the sludge cake and the waiting time for unloading of the truck often cannot be completely coordinated, there is often no truck to catch the sludge cake when it is produced, and the sludge cake will directly fall to the ground on the first floor and pile up into a soil pile. This not only causes environmental pollution in the production site, but also increases the difficulty of subsequent sludge cake transfer.

[0006] In order to complete the subsequent transfer of the sludge cake, at least two people are usually needed to manually transfer the sludge cake piled up on the ground to the ton bag for storage using a shovel. This manual transfer method not only consumes time and effort, but also greatly reduces the transfer efficiency, and the splashing of the falling sludge cake can easily cause injury to the workers. At the same time, since the sludge cake has a certain viscosity and moisture content, the manual transfer process can also cause the sludge cake to scatter and cause secondary pollution to the environment. UTILITY MODEL CONTENTS

[0007] The utility model intends to provide a shale gas produced water sludge cake recovery device to solve the problem that the existing technology cannot match the production time of the sludge cake and the waiting time for unloading of the truck.

[0008] To achieve the above object, the utility model discloses the following technical scheme: a shale gas production water sludge cake recovery device, including the support frame of the lower side of the end of the transmission belt, the sludge cake receiving hopper for receiving the sludge cake falling on the transmission belt, the sludge pipe, the sludge storage bag and the ton bag frame for fixing ton bag, the sludge cake receiving hopper is fixedly installed on the support frame, and the sludge pipe is vertically arranged below the sludge cake receiving hopper, and the discharge port of the sludge cake receiving hopper is fixedly connected with the upper end of the sludge pipe, the sludge storage bag includes the upper bag mouth and the lower bag mouth, and the upper bag mouth and the lower bag mouth of the sludge storage bag are vertically penetrated, the upper bag mouth of the sludge storage bag is fixedly connected with the lower end of the sludge pipe, the lower bag mouth of the sludge storage bag is provided with the rope bag assembly for controlling the opening and closing of the bag mouth, and the ton bag frame is arranged below the sludge storage bag.

[0009] The principle and advantages of the scheme are that: in actual application, after the sludge cake freely falls from the end of the conveying belt, first, the sludge cake is received by the sludge cake receiving hopper below; the sludge cake received by the sludge cake receiving hopper enters the vertically arranged sludge pipe through the discharge port and slides along the inner wall; the sludge cake continues to slide into the sludge storage bag; the upper bag mouth of the sludge storage bag is fixedly connected with the lower end of the sludge pipe, so that the sludge cake can smoothly enter; and the sludge cake falls into the ton bag through the lower bag mouth of the sludge storage bag;

[0010] When the ton bag tends to be full, the lower bag mouth of the sludge storage bag is tightened by operating the rope bag assembly, temporarily storing the sludge cake and preventing it from falling to the outside; at this time, the operator can replace the empty ton bag, then open the sludge storage bag by operating the rope bag assembly, and the sludge cake in the sludge storage bag falls into the new ton bag, continuing the recovery work of the sludge cake;

[0011] The device can fill the blank period of no truck receiving sludge cake below, ensuring that the sludge cake does not directly fall on the ground to cause environmental pollution and transportation difficulty; through the continuous reception and conduction of the sludge cake receiving hopper, the sludge pipe and the sludge storage bag, the splashing phenomenon of the sludge cake during falling is effectively prevented, and the risk of injury to the staff is reduced; the use of the device reduces the time and effort of manual transfer of the sludge cake, greatly improving the transportation efficiency.

[0012] As an improvement, the rope bag assembly includes a pull rope and a mouth ring channel for placing the pull rope, the mouth ring channel is arranged along the circumference of the lower bag mouth of the sludge storage bag, and the pull rope is placed in the mouth ring channel in a ring shape with the head connected to the tail; the pull rope is two, and the mouth ring channel is provided with openings at the symmetrical positions, and the rope bodies of the two pull ropes are respectively stretched out from the two openings of the mouth ring channel;

[0013] Two hand-operated hoists are hung on the support frame, and the rope bodies of the pull ropes stretched out from the two openings of the mouth ring channel are respectively hooked by the hooks of the two hand-operated hoists.

[0014] The improved beneficial effect is that the sludge storage bag is subjected to horizontal forces in two opposite directions, avoiding the sludge storage bag and sludge conveying pipe from being skewed due to pulling force, and ensuring the reliability and stability of the bag opening contraction; after the hand-operated hoist removes the pulling force on the pulling rope, the lower bag opening of the sludge storage bag is naturally squeezed open due to the accumulation of the sludge cake weight, without the need for additional operation; the structure is simple and does not require electricity, and can be flexibly applied to various environments, improving the adaptability and practicality of the equipment.

[0015] As an improvement, the sludge conveying pipe is a flexible metal hose with a diameter of 300 mm.

[0016] The improved beneficial effect is that the smoothness and stability of the sludge cake during transportation are ensured, avoiding the difficulty of transfer caused by pipe blockage or deformation.

[0017] As an improvement, the height of the hand-operated hoist is lower than the height of the lower bag opening of the sludge storage bag.

[0018] The improved beneficial effect is that the hand-operated hoist can provide a downward diagonal pulling force when the bag opening is contracted; this pulling force helps maintain the vertical state of the sludge conveying pipe and sludge storage bag, avoiding equipment skewing or damage caused by improper pulling direction; at the same time, this design also facilitates the operation and maintenance of the operator.

[0019] As an improvement, the ton bag rack is a rectangular frame body, and hooks for fixing the ton bag are arranged inward at the four corners of the upper end of the ton bag rack; the bottom of the ton bag rack is provided with a support platform for supporting the ton bag, and the lower surface of the support platform is provided with a pulley block for moving the ton bag rack.

[0020] The improved beneficial effect is that the operator can easily push the ton bag rack under the support frame or move it out of the support frame through the pulley block, realizing the rapid transfer and efficient management of the sludge cake.

[0021] As an improvement, the width of the ton bag rack is less than the width of the support frame.

[0022] The improved beneficial effect is to ensure the smoothness and flexibility of the ton bag rack when moving in and out of the support frame.

[0023] As an improvement, the bottom of the support frame is provided with a pulley block for moving the support frame.

[0024] The improved beneficial effect is that the entire recycling device can be conveniently moved and positioned; when a truck is receiving the sludge cake, the operator can easily move the support frame and the entire recycling device on it away through the pulley block, freeing up space for the truck. BRIEF DESCRIPTION OF DRAWINGS

[0025] Figure 1The utility model discloses an embodiment structure schematic view. DETAILED DESCRIPTION

[0026] The embodiment is further described in detail as follows:

[0027] The reference signs in the drawings of the specification include: a conveying belt 1, a support frame 2, a mud receiving hopper 3, a mud conveying pipe 4, a mud storage bag 5, a ton bag frame 6, a hand-operated hoist 7 and a pulling rope 8.

[0028] EMBODIMENT

[0029] The formed sludge cake is transported out by the conveying belt 1 on the second floor, the conveying end of the conveying belt 1 extends out of the second floor and is suspended, and the sludge cake is freely dropped from the end of the conveying belt 1 to the first floor outside. The conveying belt 1 is designed so that when in use, the truck used for transferring the sludge cake is parked below the end of the conveying belt 1, so that the sludge cake is directly dropped from the end of the conveying belt 1 into the car hopper of the truck, thereby improving the transfer efficiency of the sludge cake.

[0030] However, in the implementation and use process, the sludge cake production time and the truck waiting time for unloading cannot be coordinated, so that when the sludge cake is produced, there is no truck below the end of the conveying belt 1 to receive the sludge cake. This causes the sludge cake to directly fall to the ground on the first floor, and the sludge cake accumulates into a soil pile as it falls. In order to complete the subsequent transfer of the sludge cake, at least two workers need to use a shovel to manually transfer the sludge to the ton bag for storage. This causes a large amount of time and labor to be consumed in transferring the sludge cake. To solve this situation, the embodiment provides a shale gas produced water sludge cake recycling device.

[0031] Basically as shown in the accompanying Figure 1 A shale gas produced water sludge cake recycling device includes a support frame 2, a mud receiving hopper 3, a mud conveying pipe 4, a mud storage bag 5 and a ton bag frame 6.

[0032] The support frame 2 is located below the end of the conveying belt 1, and the mud receiving hopper 3 is fixedly welded to the upper end of the support frame 2, so that the mud receiving hopper 3 can receive the sludge cake dropped from the end of the conveying belt 1. The mud conveying pipe 4 is vertically arranged below the mud receiving hopper 3, the discharge port of the mud receiving hopper 3 is fixedly connected to the upper port of the mud conveying pipe 4, and the mud conveying pipe 4 is a flexible metal hose with a diameter of 300 mm.

[0033] The sludge storage bag 5 comprises an upper bag opening and a lower bag opening, the upper bag opening and the lower bag opening of the sludge storage bag 5 are vertically through, the upper bag opening of the sludge storage bag 5 is fixedly connected with the lower end of the sludge conveying pipe 4, and the lower bag opening of the sludge storage bag 5 is provided with a rope pulling bag assembly, the rope pulling bag assembly comprises a mouth ring channel and a pulling rope 8, the mouth ring channel is arranged along the lower bag opening of the sludge storage bag 5 in a circle, the pulling rope 8 is arranged in the mouth ring channel in a loop shape with the head connected with the tail, and the pulling rope 8 is arranged in the mouth ring channel in a loop shape with the head connected with the tail.

[0034] The support frame 2 is hung with two hand-operated hoists 7, the hooks of the two hand-operated hoists 7 are respectively hooked on the rope bodies of the pulling ropes 8 which are arranged at the two openings of the mouth ring channel and extend outwards.

[0035] The positions of the two hand-operated hoists 7 are lower than the height of the lower bag opening of the sludge storage bag 5, so that the pulling force borne by the pulling rope 8 is obliquely downward, and the sludge conveying pipe 4 and the sludge storage bag 5 are prevented from being upwardly deformed under the pulling action.

[0036] The lower bag opening of the sludge storage bag 5 is provided with a movable ton bag frame 6. The ton bag frame 6 is a rectangular frame body, the upper end of the ton bag frame 6 is provided with four inward hooks for fixing ton bags, and the bottom of the ton bag frame 6 is provided with a support platform for supporting the ton bags.

[0037] The width of the ton bag frame 6 is less than the width of the support frame 2, so that the ton bag frame 6 can be completely placed in the support frame 2. The bottom of the support frame 2 is also provided with a pulley set for moving the support frame 2.

[0038] The specific implementation process is as follows:

[0039] When the second-floor conveying belt 1 continuously outputs the sludge cakes, but there is no corresponding truck to receive the sludge cakes on the first floor, the support frame 2 is moved to the lower side of the conveying belt 1, and the sludge receiving hopper 3 is aligned with the end of the conveying belt 1. The sludge cakes at the end of the conveying belt 1 fall freely into the sludge receiving hopper 3, and then slide through the sludge conveying pipe 4 and the sludge storage bag 5 and finally enter the ton bag.

[0040] When the ton bag tends to be full, the hoist 7 is used to shrink the lower bag opening of the sludge storage bag 5; at this time, the sludge cake dropped from the conveying belt 1 is temporarily stored in the sludge storage bag 5. The operator can push away the full ton bag together with the ton bag frame 6 at this time, and retreat the other ton bag frame 6 fixed with the empty ton bag to the support frame 2, so that the ton bag opening is aligned with the lower bag opening of the sludge storage bag 5. Then the hoist 7 is elongated, and the pulling force on the pull rope 8 is released. Due to the accumulation of the sludge cake in the sludge storage bag 5, the lower bag opening of the sludge storage bag 5 will be squeezed open due to the weight of the sludge cake, and then the sludge cake in the sludge storage bag 5 falls into the ton bag, and the sludge cake recovery work continues.

[0041] The above is only an embodiment of the present application, and the specific technical solutions and / or common knowledge of characteristics in the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the technical solutions of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
