Description

Technical Field

[0001] This utility model relates to the field of mud treatment technology, and more specifically, to a mud extraction device for bored pile construction. Background Technology

[0002] Currently, mud wall protection technology is commonly used in the drilling of cast-in-place piles. However, the treatment of waste mud has always been a problem in construction. Waste mud contains a large amount of clay, sand and minerals, which cannot be discharged directly or allowed to settle naturally. If it is not treated in time, it will not only affect the construction but also cause environmental pollution.

[0003] In existing waste sludge treatment processes, most methods employ impurity pumps to extract the waste sludge, which is then filtered and purified by subsequent filtration equipment. However, due to the complex composition of impurities in the waste sludge, including some large mud lumps, the large mud lumps may clog the existing impurity pumps during extraction, affecting subsequent operations and potentially damaging the pumps. To address these issues, a solution is proposed below. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a drilling mud extraction device for bored pile construction, which can crush larger impurities in waste mud and avoid affecting the impurity pump.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A drilling mud extraction device for bored pile construction includes an impurity pump. The input end of the impurity pump is provided with a processing chamber, which is connected to the input end of the impurity pump. A crushing component is provided inside the processing chamber, which divides the processing chamber into an upper suction chamber and a lower crushing chamber. The crushing component is arranged at an angle. A storage component is connected to the side of the suction chamber near the lower end of the crushing component, and a suction pipe is connected to the side of the suction chamber near the higher end of the crushing component.

[0007] Preferably, the crushing assembly includes crushing rollers, rotating shafts, and a drive component. Two crushing rollers are provided, arranged symmetrically. Four rotating shafts are provided, each fixed to one end of a crushing roller, and the rotating shafts are concentric with the corresponding crushing rollers. The crushing rollers are arranged inside the processing chamber, and the rotating shafts are rotatably engaged with the side of the processing chamber. The drive component is arranged on the side of the processing chamber, and the output end of the drive component is in transmission engagement with two rotating shafts located at the same end of the two crushing rollers.

[0008] Preferably, the driving component includes a motor, pulleys, gears, a transmission belt, and universal joints. Two universal joints are provided, each fixedly connected to a different rotating shaft. A connecting rod is provided at the other end of each universal joint, and the two connecting rods are rotatably connected to the machining chamber. Two gears are provided, each connected to a different connecting rod and meshing with the other gear. Two pulleys are provided, one of which is mounted on any one of the connecting rods and fixedly connected to the connecting rod. The other pulley is mounted on the output end of the motor. The transmission belt is mounted on the outside of the two pulleys to achieve transmission.

[0009] Preferably, the storage assembly includes an outlet, an outlet pipe, and a storage container. The outlet is located on the side of the suction chamber, the outlet pipe is fixed to the side of the processing chamber, and the inlet end and outlet end of the outlet pipe are connected to each other. The other ends of the storage container and the outlet pipe are detachably connected.

[0010] Preferably, the storage bucket and the discharge pipe are connected by a threaded detachable joint.

[0011] Preferably, the discharge pipe is an L-shaped pipe.

[0012] Preferably, a controller is installed on the side of the processing chamber, and the impurity pump and the crushing assembly are both electrically connected to the controller.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] I. This solution uses an impurity pump to draw external waste mud into the processing chamber. The processing chamber is a sealed cavity and is connected to the outside via a suction pipe. That is, the processing chamber draws external waste mud into the suction chamber through the suction pipe. The waste mud falls onto the crushing component, which crushes larger mud lumps in the waste mud, preventing them from clogging the impurity pump, ensuring efficiency, and extending service life. Due to the inclined arrangement of the crushing component, hard impurities such as stones in the waste mud will move along the crushing component towards the storage component and eventually fall into the storage component. The waste mud that passes through the crushing component will fall into the crushing chamber under the action of gravity and will finally be drawn into the impurity pump and discharged through the output end of the impurity pump, completing the extraction of waste mud.

[0015] Second, the drive unit and transmission shaft rotate, which in turn drives two crushing rollers to rotate. The two crushing rollers rotate in opposite directions, thereby crushing larger mud lumps between the two crushing rollers. Hard impurities such as stones will slide down the crushing rollers, achieving separation.

[0016] Third, the drive is achieved through the cooperation of a motor, pulley, belt and universal joint. At the same time, the use of two meshing gears can ensure that the two crushing rollers rotate relative to each other to achieve the crushing effect.

[0017] IV. The outlet and discharge pipe are used to discharge un-crushed impurities from the suction chamber and collect them in the collection bucket. The detachable design makes it convenient for users to dispose of the full collection bucket.

[0018] 5. The threaded fit makes installation and disassembly convenient for users. Attached Figure Description

Detailed Implementation

[0027] Example 1:

[0028] Please see Figure 1-6A drilling mud extraction device for bored pile construction includes an impurity pump 1. The impurity pump 1 is a specially designed pump for conveying liquids containing solid impurities and is widely used in mining, metallurgy, chemical, and power industries. It is an existing special equipment and will not be discussed in detail in this application. The input end of the impurity pump 1 is provided with a processing chamber 2, and a controller 20 is provided on the side of the processing chamber 2. The impurity pump 1 and the controller 20 are electrically connected. The input end of the impurity pump 1 is connected to the bottom of the side of the processing chamber 2. The processing chamber 2 is provided with a crushing assembly 3. The crushing assembly 3 includes crushing rollers 8, rotating shafts 9, and driving components 10. There are two crushing rollers 8, which are symmetrically arranged. There are four rotating shafts 9, which are respectively fixed to the two ends of the two crushing rollers 8, and the rotating shafts 9 and the corresponding crushing rollers 8 are concentric. The crushing rollers 8 are arranged inside the processing chamber 2, and the rotating shafts 9 and the side of the processing chamber 2 are rotatably engaged. The crushing rollers 8 are arranged at an angle with the horizontal plane, and there is a gap between the two crushing rollers 8. The driving component 10 is arranged on the side of the processing chamber 2.

[0029] Waste mud and sand pass directly through the gap between the crushing rollers 8 under the action of gravity. Soil lumps are crushed by the rotating crushing rollers 8 and then pass through the gap, avoiding blockage of impurity pump 1 by larger soil lumps. Stones slide along the inclined surface of the crushing rollers 8, avoiding damage to impurity pump 1, ensuring the extraction efficiency of impurity pump 1, and extending the service life of impurity pump 1.

[0030] The drive unit 10 includes a motor 11, pulleys 12, gears 13, a transmission belt 14, and universal joints 15. There are two universal joints 15, which are fixedly connected to two rotating shafts 9 respectively. The other end of the universal joint 15 is provided with a connecting rod 16, which is arranged horizontally. A bracket is installed on the side of the processing chamber 2, and the connecting rod 16 passes through the bracket. The connecting rod 16 and the bracket are rotatably engaged. There are two gears 13, which are connected to the two connecting rods 16 respectively and mesh with each other. There are two pulleys 12, one of which is sleeved on any one of the connecting rods 16 and is fixedly connected to the connecting rod 16. The other pulley 12 is installed on the output end of the motor 11. The motor 11 is fixed on the outer side of the processing chamber 2 and is electrically connected to the controller 20. The transmission belt 14 is sleeved on the outside of the two pulleys 12 to realize transmission.

[0031] The motor 11 drives the linkage 16 to rotate, and the pulley 12 and transmission belt 14 transmit the driving force of the horizontally rotating linkage 16 to the inclined rotating shaft 9. The two meshing gears 13 ensure that the two crushing rollers 8 rotate in opposite directions, thereby ensuring the crushing effect.

[0032] The crushing roller 8 divides the processing chamber 2 into an upper suction chamber 4 and a lower crushing chamber 5. The input end of the impurity pump 1 is located on the side of the crushing chamber 5. The waste mud entering the impurity pump 1 is crushed by the crushing roller 8, thereby protecting the impurity pump 1. The suction chamber 4 is connected to the suction pipe 7 on the side near the higher end of the crushing component 3. The suction pipe 7 is used to suck the external waste mud into the suction chamber 4. The side of the suction chamber 4 near the lower end of the crushing component 3 is connected to the storage component 6.

[0033] The storage component 6 includes an outlet 17, an outlet pipe 18, and a collection container 19. The outlet 17 is located on the side of the suction chamber 4, facilitating the discharge of impurities from the suction chamber 4. The outlet pipe 18 is an L-shaped pipe, fixed to the side of the processing chamber 2, with its inlet end connected to the outlet 17. The L-shaped design allows the collection container 19 to be arranged vertically, facilitating its storage function and ensuring maximum storage capacity. The collection container 19 and the outlet pipe 18 are connected by a threaded detachable joint, which facilitates the disassembly of the collection container 19 for cleaning impurities inside. The collection container 19 and the collection pipe also seal the outlet 17, ensuring the sealing of the entire processing chamber 2. This allows the processing chamber 2 to be drawn out only through the suction pipe 7, ensuring the suction power of the suction pipe 7.

[0034] Working principle:

[0035] During use, the user places the suction pipe 7 into the waste mud. A mounting block can be installed at one end of the suction pipe 7 to ensure that one end of the suction pipe 7 is stable in the waste mud. The impurity pump 1 and motor 11 are started by the controller 20. The impurity pump 1 will draw into the processing chamber 2. Since the processing chamber 2 is sealed and has only one inlet (the suction pipe 7), the processing chamber 2 will draw the waste mud out through the suction pipe 7. The waste mud enters the processing chamber 2 through the suction pipe 7 and falls into the suction chamber 4 first. Due to the isolation of the crushing roller 8, mud and stones will fall onto the crushing roller 8. The waste mud and sand will pass through the gap between the two crushing rollers 8. Under the action of gravity, the waste mud and sand fall into the crushing chamber 5. Finally, the impurity pump 1 will suck the waste mud into the impurity pump 1 and then discharge it through the output end of the impurity pump 1.

[0036] Simultaneously, due to the start of motor 11, motor 11 drives the fixedly connected pulley 12 to rotate. The pulley 12 on motor 11 drives the pulley 12 on connecting rod 16 to rotate via transmission belt 14. Connecting rod 16 is driven by pulley 12, and the rotation of connecting rod 16 drives the corresponding gear 13 to rotate. Gear 13 drives another meshing gear 13 to rotate, thereby driving the other connecting rod 16 to rotate. That is, both rotating rods will rotate. Due to the transmission characteristics of gear 13, the two rotating rods will rotate in opposite directions. Connecting rod 16 drives the two crushers through universal joint 15. Rollers 8 rotate in opposite directions, crushing mud lumps through the gaps. The crushed mud lumps fall into the crushing chamber 5 and are then drawn out by the impurity pump 1. Hard impurities such as stones move towards the shorter end of the crushing rollers 8 due to the inclined arrangement of the rollers, until they fall into the collection bucket 19 through the discharge port 17 and the discharge pipe 18. The collection bucket 19 serves to collect the impurities. When the collection bucket 19 is almost full, it can be rotated to separate the collection bucket 19 from the discharge pipe 18, making it easy to clean the inside of the collection bucket 19.
