Description

Technical Field

[0001] The present application relates to the technical field of sand cleaning equipment, and in particular to a sand cleaning component with controllable trajectory. Background Art

[0002] Due to the complexity of urban organic solid waste and agricultural waste and many uncontrollable factors in the pretreatment process (such as equipment wear, misoperation, etc.), the slurry entering the anaerobic fermentation system after pretreatment contains a certain amount of sand and gravel. The specific content is related to the impurity removal efficiency of the pretreatment system and the total amount of impurities contained in the raw materials.

[0003] Therefore, the accumulation of sediments at the bottom of the tank seriously affects the normal operation of the anaerobic fermentation system of organic waste, and reasonable and effective measures must be taken to minimize the impact. At present, most continuous fermentation biogas projects regularly clean the reactor as a whole to discharge the accumulated sand during actual operation, which consumes a lot of manpower and material resources, and requires a lot of time to restart the fermentation system, which seriously affects the normal operation of the project. At present, with the continuous increase in the commissioning time of biogas projects, a large number of anaerobic reactors have different degrees of sediment accumulation problems at the bottom of the tank. The cost of stopping production and cleaning the tank is too high for the operation of the project, so a large number of reaction tanks are in a sick operation state. Therefore, the anaerobic fermentation tank that has been in operation is equipped with an online tank continuous sand removal technology to directly remove the sediment at the bottom of the tank from the operation, so as to greatly reduce the harm caused by the existing anaerobic tank sediment and extend the tank cleaning cycle.

[0004] The sand cleaning device in the prior art generally includes a sand discharge pipe extending into the anaerobic tank, and then the other end of the sand discharge pipe is passed into the solid-liquid separation device to separate the solid sediment from the liquid, and then the liquid is transported back to the tank body. Although this type of sand cleaning device can extract the sediment in the tank body, since the position of the sand discharge pipe port in the tank body is always fixed, there are many dead corners in the tank body, and the sediment cannot be removed in time.

[0005] In view of this, there is an urgent need for a sand cleaning component with controllable trajectory. Summary of the invention

[0006] In view of the problems existing in the prior art, the present application solves the problems with the following technical structure.

[0007] To achieve the above objectives, this application adopts the following technical solutions:

[0008] A trajectory-controllable sand cleaning assembly comprises: a sand discharge pipe, an adjusting device and two adjusting channels, wherein the adjusting device is used to extend the sand discharge pipe into a tank body or to draw it out of the tank body;

[0009] The outlets of the two regulating channels are arranged opposite to each other on the side of the suspended end ring of the sand discharge pipe, and the two regulating channels are externally connected to high-pressure water flow;

[0010] A sand discharge channel is arranged in the sand discharge pipe.

[0011] It is further characterized in that

[0012] The sand discharge pipe comprises an outer pipe and an inner pipe penetrating the outer pipe, the sand discharge channel is arranged between the inner side of the outer pipe and the outer side of the inner pipe, and one end of the inner pipe is externally connected to a high-pressure water flow.

[0013] Two groups of partitions are arranged between the inner side of the outer tube and the outer side of the inner tube. Each group of partitions, the outer tube and the inner tube form an adjustment channel. Both sides of the two adjustment channels are sand discharge channels.

[0014] The outer tube and the inner tube are coaxially arranged.

[0015] A bending sensor is arranged on one side of the two adjustment channels.

[0016] The adjusting device comprises a frame, a sliding seat and a driving mechanism. The sliding seat is slidably arranged on the frame, the sand discharge pipe is arranged on the sliding seat, and the driving mechanism is used for driving the sliding seat to slide on the frame.

[0017] The driving mechanism comprises a motor and a screw rod, the screw rod is rotatably arranged on the frame, the sliding seat is penetrated on the screw rod, the sliding seat is threadedly connected with the screw rod, and the motor is arranged on the frame for driving the screw rod to rotate.

[0018] A plurality of pulleys are arranged at the bottom of the frame.

[0019] The driving mechanism further comprises a height adjusting rod, which is arranged on the frame, and one end of the height adjusting rod is connected to the sand discharge pipe for adjusting the horizontal height of the sand discharge pipe.

[0020] The frame is provided with a slide rail, and the slide seat is clamped on the slide rail.

[0021] The above structure of the present application can achieve the following beneficial effects:

[0022] When cleaning sand, the sand discharge pipe is connected to a solid-liquid separation device, and the two adjusting channels are connected to high-pressure water flow.

[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0027] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present application and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, area, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0028] The following combination Figure 1-Figure 2 And further explain this application in detail.

[0029] like Figure 1-2As shown, a trajectory-controllable sand cleaning component comprises: a sand discharge pipe, an adjusting device 1 and two adjusting channels 2, wherein the adjusting device 1 is used to extend the sand discharge pipe into the tank body or to pull it out of the tank body; the outlets of the two adjusting channels 2 are relatively arranged at the side of the suspended end ring of the sand discharge pipe; a sand discharge channel 3 is arranged in the sand discharge pipe, so that when cleaning sand, the sand discharge pipe is externally connected to a solid-liquid separation device (to separate the solid sediment in the mortar discharged by the sand discharge pipe), the two adjusting channels 2 are externally connected to a high-pressure water flow, and the sand discharge pipe is inserted into the tank body (or the bottom of the pool) through the adjusting component 1. The length of the sand discharge pipe entering the tank body can be controlled by the adjusting component 1. When the direction of the end of the sand discharge pipe needs to be adjusted, high-pressure water flow is injected into one of the adjusting channels 2. Since the outlet of the adjusting channel 2 is located on the ring side of the end of the sand discharge pipe (that is, the side of the sand discharge pipe), when the high-pressure water flow is ejected from the outlet, the sand discharge pipe has a reverse thrust, so that the sand discharge pipe is turned. The adjusting component 1 is used to control the length of the sand discharge pipe entering the tank body, so as to expand the sand cleaning area, improve the sand cleaning efficiency, and avoid the problem of dead corners in the tank body that cannot be cleaned.

[0030] like Figure 1-2 As shown, the sand discharge pipe includes an outer tube 4 and an inner tube 5 inserted in the outer tube 4. The outer tube 4 and the inner tube 5 are preferably coaxially arranged. The sand discharge channel 3 is arranged between the inner side of the outer tube 4 and the outer side of the inner tube 5. One end of the inner tube 5 is externally connected to a high-pressure water flow. In this way, when cleaning sand, the high-pressure water flow sprayed from the inner tube 5 flushes the sediment in the tank body, and then discharges the sediment from the tank body through the sand discharge channel 3, thereby further improving the efficiency of sand cleaning.

[0031] like Figure 1-2 As shown, two groups of partitions 6 are arranged relatively between the inner side of the outer tube 4 and the outer side of the inner tube 5, and an adjustment channel 2 is formed between each group of partitions 6, the outer tube 4 and the inner tube 5. The two sides of the two adjustment channels 2 are between the sand discharge channels 3. In this way, the annular channel outside the inner tube 5 is divided into four channels by the two groups of partitions 6. The two adjustment channels 2 and the two sand discharge channels 3 are arranged at intervals to control the turning of the end of the sand discharge pipe while ensuring the normal progress of the sand discharge work.

[0032] What is further optimized is that in order to adjust the sand discharge pipe in time according to the end position of the sand discharge pipe, a bending sensor 7 is provided on one side of the two adjustment channels 2, so that the length of the sand discharge pipe entering the tank body can be calculated based on the bending degree of the sand discharge pipe detected by the bending sensor 7, and then the position of the end of the sand discharge pipe can be accurately controlled to efficiently clean the sand.

[0033] like Figure 1As shown, in order to realize the movement of the sand discharge pipe, the adjusting device 1 includes a frame 11, a sliding seat 12 and a driving mechanism. The sliding seat 12 is slidably arranged on the frame 11 (a slide rail is arranged on the frame 11, and the sliding seat 12 is clamped on the slide rail to guide and limit the movement of the sliding seat 12). The sand discharge pipe is arranged on the sliding seat 12, and the driving mechanism is used to drive the sliding seat 12 to slide on the frame 11, wherein the driving mechanism specifically includes a motor 13 and a screw rod 14, the screw rod 14 is rotatably arranged on the frame 11, the sliding seat 12 is penetrated on the screw rod 14, the sliding seat 12 is threadedly connected with the screw rod 14, and the motor 13 is arranged on the frame 11 for driving the screw rod 14 to rotate. In this way, the screw rod 14 is driven to rotate by the motor 13, so that the sliding seat 12 is translated on the frame 11 (the sliding seat 12 is close to or away from the tank body), so that the sand discharge pipe is penetrated into the tank body or pulled out of the tank body, so as to achieve the purpose of adjusting the end position of the sand discharge pipe.

[0034] It is further optimized that, in order to improve the convenience of using the device, a plurality of pulleys 15 are provided at the bottom of the frame 11, so that the device can be moved conveniently.

[0035] Further optimization is that the driving mechanism also includes a height adjustment rod 16, which is arranged on the frame 11. One end of the height adjustment rod 16 can be connected to the sand discharge pipe, and the other end can be arranged on the frame 11 or the sliding seat 12. By adjusting the height of the height adjustment rod 16 or setting the height adjustment rod 16 as a telescopic rod, the horizontal height of the sand discharge pipe can be adjusted to adapt to tank interfaces of different heights.

[0036] In summary, when cleaning sand, the sand discharge pipe is connected to a solid-liquid separation device, the two adjusting channels 2 are connected to a high-pressure water flow, and the sand discharge pipe is inserted into the tank body through the adjusting component 1. The length of the sand discharge pipe entering the tank body can be controlled by the adjusting component 1. When the direction of the end of the sand discharge pipe needs to be adjusted, high-pressure water flow is injected into one of the adjusting channels 2. Since the outlet of the adjusting channel 2 is located on the ring side of the end of the sand discharge pipe, when the high-pressure water flow is ejected from the outlet, the sand discharge pipe has a reverse thrust, which makes the sand discharge pipe turn. The adjusting component 1 is cooperated to control the length of the sand discharge pipe entering the tank body, so as to expand the sand cleaning area, improve the sand cleaning efficiency, and avoid the problem of dead corners in the tank body that cannot be cleaned.

[0037] The above are only preferred embodiments of the present application, and the present application is not limited to the above embodiments. It is understood that other improvements and changes directly derived or associated by those skilled in the art without departing from the spirit and concept of the present application should be considered to be included in the protection scope of the present application.
