Description

Technical Field

[0001] This utility model belongs to the field of power device technology, specifically a power device and sludge scraping device suitable for closed sludge ponds. Background Technology

[0002] In the field of radioactive waste treatment, precipitation is a common method for removing radioactive elements from wastewater. This process generates a large amount of precipitate, most of which has a high water content and requires dewatering for subsequent storage and disposal. To better integrate with subsequent processes, the precipitate can be temporarily stored in a horizontal flow, closed sludge tank.

[0003] With increasingly stringent environmental protection requirements and a growing volume of sludge treatment, traditional power units used for sludge treatment are gradually revealing numerous problems. Traditional power units connect directly to the sludge scraping system via a reducer, lacking buffering and adjustment mechanisms in the power transmission link. During prolonged operation or when the load fluctuates, issues such as wear, fatigue, and poor lubrication of the gears inside the reducer can easily lead to power transmission interruptions and stalls, failing to guarantee a continuous and stable power supply to the working components and thus affecting the continuity of the entire operation process.

[0004] Based on this, the present invention provides a novel power device and sludge scraping device suitable for closed sludge ponds to overcome the above-mentioned defects. Utility Model Content

[0005] The purpose of this utility model is to provide a power device suitable for closed sludge tanks. In this power device, the power component is connected to the main power mechanism and then to the eccentric power mechanism in a continuous transmission link. This not only ensures a continuous and stable power supply and avoids jamming and interruption in the power transmission process, ensuring the continuous operation of sludge treatment, but also converts the rotational motion into linear reciprocating motion through the eccentric structure, adapting to the motion requirements of operating components such as the sludge scraping system.

[0006] This utility model adopts the following technical solution: a power device suitable for closed sludge tanks, the power device comprising:

[0007] A power component, which provides power;

[0008] The box contains storage space.

[0009] A main power mechanism is installed within the housing space of the box and is connected to the power component via transmission.

[0010] An eccentric power mechanism is installed within the housing space of the box and is connected to the main power mechanism for transmission; the output end of the eccentric power mechanism is connected to the drive rod, driving the reciprocating motion of the drive rod.

[0011] Furthermore, the main power mechanism includes a drive shaft and a first drive gear mounted on the drive shaft, with both ends of the drive shaft respectively mounted on the side wall of the housing.

[0012] Furthermore, a second drive gear is provided at the input end of the drive shaft for transmission connection with the power component.

[0013] Furthermore, the second drive gear is connected to the power component via a reducer.

[0014] Furthermore, the eccentric power mechanism includes two driven gears arranged in parallel, a connecting rod whose two ends are respectively connected to the two driven gears, and two driven shafts fixedly installed on the side of the driven gears near the side wall of the housing;

[0015] Both driven gears mesh with the first driving gear, the connecting rod is offset from the center of the driven gear, and the connecting rod is connected to the driving rod.

[0016] Furthermore, a bearing is provided at the connection between the driven shaft and the housing.

[0017] Furthermore, the two driven gears are symmetrically arranged, and the connecting rod is horizontally arranged and located near the outer edge of the driven gear.

[0018] Furthermore, the drive rod includes a connecting rod body, a connector disposed at one end of the connecting rod body, and a booster block disposed at the other end of the connecting rod body;

[0019] The booster block has a rectangular through hole in its center, and the connecting rod of the eccentric power mechanism is placed in the through hole in the center of the booster block.

[0020] Furthermore, the connecting rod body and the booster block are connected by threads.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] In this invention, when the power unit is working, the power component starts, and the output power is transmitted to the main power mechanism. The main power mechanism then transmits the power to the eccentric power mechanism. The eccentric power mechanism utilizes the principle of eccentric structure to convert rotational motion into linear reciprocating motion. Its output end is connected to a drive rod, thereby driving the drive rod to perform reciprocating motion. The drive rod can be further connected to a sludge scraping system or other operating components in a closed sludge tank to realize operations such as sludge scraping, meeting the requirements of sludge treatment processes.

[0023] The continuous transmission link of the power components in this power unit, from the main power mechanism to the eccentric power mechanism, not only ensures a continuous and stable power supply and avoids jamming and interruption in the power transmission process, ensuring the continuous operation of sludge treatment, but also converts rotary motion into linear reciprocating motion through the eccentric structure, adapting to the motion requirements of operating components such as the sludge scraping system.

Detailed Implementation

[0032] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] The following is in conjunction with the appendix Figure 1 To be continued Figure 5 The present invention will be described in detail with reference to specific embodiments:

[0034] like Figure 1-5 As shown, this utility model discloses a power device suitable for closed sludge tanks, the power device comprising:

[0035] A power component (not shown in the figure) is used to provide power; in this embodiment, the power component is a motor.

[0036] Box 2, which has a storage space 20 inside;

[0037] The main power mechanism 3 is installed in the receiving space 20 of the housing 2 and is connected to the power component for transmission.

[0038] An eccentric power mechanism 4 is installed in the accommodating space 20 of the housing 2 and is connected to the main power mechanism 3 for transmission. The output end of the eccentric power mechanism 4 is connected to the drive rod 5 to drive the reciprocating motion of the drive rod 5.

[0039] In this invention, when the power device is working, the power component starts, and the output power is transmitted to the main power mechanism 3. The main power mechanism 3 then transmits the power to the eccentric power mechanism 4. The eccentric power mechanism 4 utilizes the principle of eccentric structure to convert rotational motion into linear reciprocating motion. Its output end is connected to the drive rod 5, thereby driving the drive rod 5 to perform reciprocating motion. The drive rod 5 can be further connected to the sludge scraping system or other operating components in the closed sludge tank to realize operations such as sludge scraping, meeting the requirements of the sludge treatment process.

[0040] The continuous transmission link of the power components in this power unit, from the main power mechanism 3 to the eccentric power mechanism 4, not only ensures a continuous and stable power supply and avoids jamming and interruption in the power transmission process, ensuring the continuous operation of sludge treatment, but also converts the rotational motion into linear reciprocating motion through the eccentric structure, adapting to the motion requirements of operating components such as the sludge scraping system.

[0041] Furthermore, in some specific embodiments, the main power mechanism 3 includes a drive shaft 30 and a first drive gear 31 mounted on the drive shaft 30. The two ends of the drive shaft 30 are respectively mounted on the side wall of the housing 2. A bearing 6 is provided at the connection between the drive shaft 30 and the housing 2. The bearing supports the two ends of the drive shaft 30 to realize the rotational connection between the drive shaft 30 and the housing 2.

[0042] More specifically, a second drive gear 32 may be provided at the input end of the drive shaft 30 for transmission connection with the power component. In this embodiment, the second drive gear 32 is transmission connected to the power component through a reducer.

[0043] Furthermore, in some specific embodiments, the eccentric power mechanism 4 includes two driven gears 40 arranged in parallel, a connecting rod 41 with both ends connected to the two driven gears 40 respectively, and two driven shafts 42 fixedly installed on the side of the driven gears 40 near the side wall of the housing 2. The driven shaft 42 is provided with a bearing 6 at the connection between it and the housing 2, and the end of the driven shaft 42 is supported by the bearing to realize the rotational connection between the driven shaft 42 and the housing 2.

[0044] Both driven gears 40 mesh with the first driving gear 31 to transmit power. The connecting rod 41 is offset from the center of the driven gears 40 and is connected to the drive rod 5. In this embodiment, the two driven gears 40 are symmetrically arranged, and the connecting rod 41 is horizontally positioned near the outer edge of the driven gears 40 to avoid torque imbalance. Simultaneously, it maximizes the use of eccentricity to achieve an effective conversion from rotary motion to linear reciprocating motion, ensuring the maximum displacement variation of the connecting rod 41 in the horizontal direction.

[0045] Two parallel driven gears 40 are connected by a connecting rod 41, forming a relatively stable mechanical structure. When the driven gear 40 receives power from the driving force mechanism 3 and rotates, the coordinated action of the gears on both sides creates a mutual balance, making the power output of the entire eccentric power mechanism 4 more stable. This avoids vibrations and jamming caused by uneven force on one side, providing a stable reciprocating driving force for the drive rod 5 and ensuring the smooth progress of sludge treatment operations.

[0046] Meanwhile, the connecting rod 41 is offset from the center of the driven gear 40, which utilizes the principle of eccentricity to convert the rotational motion of the driven gear 40 into linear reciprocating motion and directly transmit it to the drive rod 5. The structure is simple and, compared with the complex multi-stage transmission conversion method, reduces the energy loss in the intermediate links and improves mechanical efficiency. It can drive the sludge scraping system or other working parts with stronger and more stable linear reciprocating power, meeting the requirements of sludge treatment for motion form and power intensity.

[0047] Furthermore, in some specific embodiments, such as Figure 4 As shown, the drive rod 5 has been further refined in design, with the following specific design scheme: The drive rod 5 includes a connecting rod body 50, a connector 51 located at one end of the connecting rod body 50, and a booster block 52 located at the other end of the connecting rod body 50. The connector 51 is used to connect with the sludge scraping system to realize the sludge scraping operation. The booster block 52 is elongated and has a rectangular through hole in the middle. Correspondingly, the connecting rod 41 in the eccentric power mechanism 4 is placed in the through hole in the middle of the booster block 52. The elongated booster block 52 can play a reciprocating motion role to a certain extent, similar to the lever principle. When the connecting rod 41 pushes the booster block 52, due to the shape characteristics of the booster block 52, the force from the connecting rod 41 can be more effectively converted into the power to push the sludge scraping system, thereby enhancing the sludge scraping effect.

[0048] More specifically, the connecting rod body 50 and the booster block 52 are connected by threads, which facilitates disassembly and installation.

[0049] Based on the aforementioned power device suitable for closed sludge ponds, this utility model further provides a sludge scraping device, which includes the aforementioned power device suitable for closed sludge ponds. This sludge scraping device possesses at least all the technical solutions and advantages of the aforementioned power device suitable for closed sludge ponds, which will not be elaborated further here.

[0050] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
