Description

Technical Field

[0001] This utility model relates to the technical field of mud cleaning devices, and more specifically, to a mud cleaning device for anti-seepage wall construction. Background Technology

[0002] In water conservancy and hydropower projects, dike reinforcement, and diaphragm wall construction, the anti-seepage wall is the core concealed structure ensuring the safety of seepage prevention. During its construction, the drilling mud plays a crucial role in stabilizing the borehole wall, suspending and carrying drill cuttings, and cooling and lubricating the drilling tools. The recycled drilling mud will mix with a large amount of formation drill cuttings and ineffective components. If the contaminated mud is reused directly without effective purification, it will not only severely weaken the wall protection effect and lead to a sharp increase in the risk of borehole collapse, but also accelerate the wear and tear of equipment such as mud pumps and drill bits. At present, the mainstream technology for mud cleaning in the industry mostly adopts a combination of "vibrating screen coarse screening + sedimentation tank fine settling": the vibrating screen separates large blocky impurities by vibrating the screen, while the sedimentation tank separates fine particles by gravity settling. However, the existing cleaning devices are prone to accumulating impurities at the screen, requiring frequent shutdowns to clean the impurities on the screen, resulting in low construction efficiency. Moreover, the sedimentation separation of fine particles requires a long waiting time and a long construction cycle. Therefore, there is an urgent need for a mud cleaning device for anti-seepage wall construction to solve the above problems. Utility Model Content

[0003] In view of the aforementioned problems, and in conjunction with the first aspect of this utility model, an embodiment of this utility model provides a mud cleaning device for anti-seepage wall construction, which is achieved by the following specific technical means:

[0004] A mud cleaning device for anti-seepage wall construction includes a support, a feed hopper and a screen. The feed hopper is fixedly connected to the top of the support, the screen is provided at the bottom of the feed hopper, multiple dampers are connected to the bottom of the screen, a collection hopper is provided at the bottom of the screen, and a screw pump is provided at the bottom of the collection hopper.

[0005] One end of the screw pump is connected to a separation cylinder, and one end of the separation cylinder is provided with an end cap. A screen cylinder is rotatably connected inside the separation cylinder, and a rotatable spiral push rod is provided inside the screen cylinder. One end of the spiral push rod is connected to a transmission assembly, and one end of the transmission assembly is connected to a drive motor. A mounting bracket is provided at the bottom of the drive motor.

[0006] According to a preferred embodiment, two sets of connecting plates are respectively provided on both sides of the screen, and multiple sets of dampers are connected to the bottom of both sets of connecting plates. A vibration motor is installed on the top of one set of connecting plates, and a waste trough is provided on one side of the other set of connecting plates.

[0007] According to a preferred embodiment, both the screen and the waste trough are inclined.

[0008] According to a preferred embodiment, the separating cylinder is provided with a material distribution chamber, the bottom of the material distribution chamber is provided with a material outlet, and a material outlet frame is detachably connected to the bottom of the material outlet;

[0009] The material distribution chamber is detachably connected to a first bearing at one end, and a second bearing is provided at one end of the end cover. The first bearing is connected to the screen cylinder around its periphery, and one end of the screen cylinder passes through the second bearing. Multiple sets of screen holes are evenly opened around the periphery of the screen cylinder.

[0010] According to a preferred embodiment, the transmission assembly includes a first gear, a second gear, and a connecting member;

[0011] The main shaft of the drive motor is connected to the first gear, one side of the first gear is connected to the connector, one end of the connector is connected to the helical push rod, and the second gear is rotatably connected to one side of the mounting bracket.

[0012] According to a preferred embodiment, the transmission assembly further includes a first pulley, a second pulley, and a connecting shaft;

[0013] The connecting shaft is connected to one side of the second gear, and the first pulley is fixedly connected to one end of the connecting shaft. The second pulley is fixedly connected to one end of the screen cylinder, and the same set of belts is fitted on the first pulley and the second pulley.

[0014] According to a preferred embodiment, the bottom of the separation cylinder is provided with a waste residue outlet.

[0015] According to a preferred embodiment, one end of the screen cylinder has multiple sets of through holes, and the positions of the multiple sets of through holes correspond to the waste residue inlet.

[0016] Based on the above aspects, this utility model has the following beneficial effects:

[0017] First, the user can control the start of the vibrating motor, which continuously conveys the mud to be processed to the feed hopper. When the mud flows onto the screen, due to the inclined screen setting, the vibrating motor continuously drives the screen to vibrate, and larger impurities in the mud will be screened out by the screen. Then, the mud rolls down the inclined surface of the screen into the waste trough, realizing continuous cleaning of the mud without stopping the machine to clean the screen, thus improving work efficiency.

[0018] Secondly, after the slurry is initially screened by a screen, it is transported to the screen cylinder by a screw pump. The drive motor and transmission components drive the spiral pusher and screen cylinder to rotate. The centrifugal force generated by the rotation of the screen cylinder causes the slurry to pass through the screen holes and enter the distribution chamber, and finally separate from the discharge port. Meanwhile, the fine impurities in the slurry are blocked in the screen cylinder. The rotation of the spiral pusher in the screen cylinder drives the fine impurities to the through hole at one end of the screen cylinder, and then discharges from the waste slag outlet. This process can continuously separate the fine impurities in the slurry. At the same time, the centrifugal force of the screen cylinder separates the fine impurities from the slurry, which improves the separation efficiency of the device for fine impurities.

[0026] The present invention will now be described in detail with reference to the accompanying drawings.

Figure 5 This is a schematic diagram of the material distribution chamber in a mud cleaning device for seepage prevention wall construction provided by an embodiment of the present invention. The following is a detailed description of this mud cleaning device for seepage prevention wall construction.

[0027] A mud cleaning device for anti-seepage wall construction includes a support 100, a feed hopper 101, and a screen 102. The feed hopper 101 is fixedly connected to the top of the support 100, and the screen 102 is provided at the bottom of the feed hopper 101. Multiple dampers 103 are connected to the bottom of the screen 102, and a collection hopper 104 is provided at the bottom of the screen 102. A screw pump 105 is provided at the bottom of the collection hopper 104. The screw pump 105 is electrically connected to an external control module (not shown in the figure). The screw pump 105 can be a G40-1VW102 model.

[0028] Understandably, the support frame 100 supports the entire device and ensures the stability of the entire device when the screen 102 initially processes the mud. The collection hopper 104 is used to collect the mud after the screen 102 has removed larger impurities, and the collected mud is transported by the screw pump 105 so that smaller impurities in the mud can be separated in the subsequent process.

[0029] One end of the screw pump 105 is connected to a separation cylinder 106. The separation process of fine impurities in the mud is carried out in the separation cylinder 106. One end of the separation cylinder 106 is provided with an end cover 107. The end cover 107 is removable, which makes it easy for users to disassemble the internal parts of the separation cylinder 106, thus improving the practicality of the device. A screen cylinder 108 is rotatably connected inside the separation cylinder 106. The screen cylinder 108 can separate fine impurities in the mud. A rotatable spiral push rod 109 is provided inside the screen cylinder 108. One end of the spiral push rod 109 is connected to a transmission component. One end of the transmission component is connected to a drive motor 110. The drive motor 110 is electrically connected to an external control module. A mounting bracket 111 is provided at the bottom of the drive motor 110.

[0030] It should be noted that the drive motor 110 can drive the screen cylinder 108 and the spiral push rod 109 to rotate through the transmission assembly. The centrifugal force generated by the rotation of the screen cylinder 108 can cause the mud to flow out of the screen cylinder 108, while the fine impurities remain inside the screen cylinder 108. At the same time, the rotation of the spiral push rod 109 can continuously transport the fine impurities inside the screen cylinder 108 for subsequent cleaning of the fine impurities.

[0031] Two sets of connecting plates 112 are respectively provided on both sides of the screen 102. Multiple sets of dampers 103 are connected to the bottom of both sets of connecting plates 112. A vibration motor 113 is installed on the top of one set of connecting plates 112. The vibration motor 113 is electrically connected to an external control module. The vibration motor 113 can be a YZU-10-4 model. A waste trough 114 is provided on one side of the other set of connecting plates 112.

[0032] Understandably, when the mud falls onto the screen 102 through the feed hopper 101, the user can start the vibration motor 113 through the control module to make the screen 102 vibrate continuously, thereby improving the efficiency of removing larger impurities from the mud. At the same time, the multiple sets of dampers 103 at the bottom of the screen 102 can prevent the screen 102 from vibrating too much and colliding with other components, thus improving the reliability of the device.

[0033] Both the screen 102 and the waste trough 114 are inclined. During the continuous vibration of the screen 102 driven by the vibrating motor 113, due to the inclined setting of the screen 102, larger impurities screened out will continuously roll down the inclined surface of the screen 102 into the waste trough 114, and then roll down the inclined surface of the waste trough 114. Users can set up a collection device at the opening of the waste trough 114 to collect larger impurities. Users do not need to stop the machine to clean the screen 102, thus achieving continuous cleaning of the mud and improving work efficiency.

[0034] The separation cylinder 106 is provided with a material distribution chamber 116. The bottom of the material distribution chamber 116 is provided with a discharge port. The bottom of the discharge port is detachably connected to a discharge frame 117. After the mud is separated from the screen cylinder 108, it enters the material distribution chamber 116 and then flows out from the discharge port to the discharge frame 117, thus realizing the separation of mud. Users can set a container at the bottom of the discharge frame 117 to collect the cleaned mud.

[0035] One end of the material distribution chamber 116 is detachably connected to a first bearing 118, and one end of the end cover 107 is provided with a second bearing 119. The periphery of the first bearing 118 is connected to the screen cylinder 108, and one end of the screen cylinder 108 passes through the second bearing 119. The first bearing 118 and the second bearing 119 can ensure the smooth rotation of the screen cylinder 108 and prevent the screen cylinder 108 from getting stuck during rotation, resulting in insufficient centrifugal force and inability to throw out the mud. Multiple sets of screen holes are evenly opened on the periphery of the screen cylinder 108.

[0036] The transmission assembly includes a first gear 120, a second gear 121, and a connecting member 122;

[0037] The main shaft of the drive motor 110 is connected to the first gear 120. One side of the first gear 120 is connected to the connector 122. One end of the connector 122 is connected to the spiral push rod 109. The second gear 121 is rotatably connected to one side of the mounting bracket 111.

[0038] The transmission assembly also includes a first pulley 123, a second pulley 124, and a connecting shaft 125;

[0039] The second gear 121 is connected to a connecting shaft 125 on one side. A first pulley 123 is fixedly connected to one end of the connecting shaft 125. A second pulley 124 is fixedly connected to one end of the screen cylinder 108. The same set of belts 126 are fitted on the first pulley 123 and the second pulley 124.

[0040] It should be noted that the user can start the drive motor 110 through the external control module. The drive motor 110 drives the first gear 120 and the connecting part 122 to rotate, thereby driving the spiral push rod 109 to rotate inside the screen cylinder 108, continuously conveying the fine impurities inside the screen cylinder 108 to the through hole 115. The rotation of the first gear 120 drives the second gear 121 and the connecting shaft 125 to rotate, thereby driving the first pulley 123 to rotate. The first pulley 123 drives the second pulley 124 to rotate through the belt 126, thereby driving the screen cylinder 108 to rotate, continuously cleaning the mud.

[0041] The bottom of the separation cylinder 106 is provided with a waste slag outlet 127, and one end of the screen cylinder 108 is provided with multiple sets of through holes 115. The positions of the multiple sets of through holes 115 correspond to the waste slag outlet 127. Fine impurities in the screen cylinder 108 are continuously transported to the through holes 115 of the screen cylinder 108 through the spiral push rod 109, and finally discharged from the separation cylinder 106 through the waste slag outlet 127, thereby realizing continuous cleaning of mud and improving work efficiency.

[0042] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
