[0002] In the fields of chemical engineering, environmental protection, and mining, slurry circulation pumps are key equipment for conveying high-concentration solid-liquid mixtures, and the accuracy of their installation elevation directly affects the system's operating efficiency and stability.

[0003] However, existing technologies have the following drawbacks:

[0004] In new energy material plants, desulfurization slurry circulation pumps are arranged closely together in a small space, making it impossible for large adjustment machinery to enter. Even if traditional jacks are placed in the small space, the exposed part of the circulation pump base is too short, making it difficult for the jack head to directly act on the circulation pump base. Furthermore, the jacks with fixed lifting strokes cannot adapt to circulation pump bases of different heights, making it difficult to accurately adjust the elevation of the circulation pump.

[0005] Therefore, in order to solve the above problems, this utility model proposes a slurry circulation pump elevation adjustment device that can be used in a confined space and can adapt to circulation pump bases of different heights. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0024] Figure 2 This is a cross-sectional schematic diagram of the middle connection part of the elevation adjustment device of the slurry circulation pump described in this utility model. Detailed Implementation

[0025] The following description is intended to provide a detailed account of the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0026] See Figure 1 This utility model provides a technical solution: an elevation adjustment device for a slurry circulation pump, wherein an installation space A is reserved on the horizontal outer side of the slurry circulation pump 100, and a pump base 400 is provided below the slurry circulation pump 100. In the horizontal direction, the outer periphery of the pump base 400 is arranged close to the outer periphery of the slurry circulation pump 100. The elevation adjustment device comprises:

[0027] Jack 200 is installed in the installation space A. The lifting direction of the jack 200 is vertical. The top of the jack 200 is located at the upper end of the jack 200.

[0028] The connecting member 300 includes a lower connecting part 301, a middle connecting part 302, and an upper connecting part 303 connected sequentially from bottom to top. The lower connecting part 301 and the upper connecting part 303 are located on opposite sides of the middle connecting part 302 in the horizontal direction. The upper connecting part 303 is connected to the top of the jack 200. The length of the middle connecting part 302 in the vertical direction is adjustable. The lower connecting part 301 is configured to be hidden and supported below the outer periphery of the pump base 400.

[0029] In this embodiment, the outer periphery of the pump base 400 extends horizontally into the installation space A to form an exposed portion 401, and the lower connecting portion 301 is hidden and supported below the exposed portion 401.

[0030] The slurry circulation pump 100 is a desulfurization slurry circulation pump, and the slurry circulation pump 100 is located in the new energy materials plant.

[0031] Regarding the specific structure of the jack 200, the jack 200 is existing technology. A reliable jack 200 is selected as the core power source of the device. The jack 200 is made of a sturdy metal shell to ensure that it can withstand greater pressure without deformation during operation. The jack 200 contains a hydraulic system or mechanical transmission mechanism, and the lifting and lowering actions of the jack 200 are driven by a manual operating lever.

[0032] Furthermore, the top part of the jack 200 is specially treated to ensure a firm weld with the upper connecting part 303 in the connecting member 300, so as to ensure that there will be no loosening or slippage during the transmission of lifting force.

[0033] See also Figure 1 Regarding the specific structure of the connecting member 300, in terms of material, the connecting member 300 is made of high-strength high-quality alloy steel. The alloy steel undergoes a special heat treatment process, which gives it extremely high strength and hardness, enabling it to withstand enormous pressure and tension. At the same time, the alloy steel also has good corrosion resistance, and can maintain stable performance for a long time in the special environment of the new energy material plant.

[0034] Furthermore, the surface of the connecting member 300 is finely polished and rust-proofed, which increases its smoothness and wear resistance, and reduces frictional wear with other components during use.

[0035] In terms of shape and structure, the lower connecting part 301, the middle connecting part 302 and the upper connecting part 303 connected from bottom to top in the connecting member 300 form an approximately “Z” shape design to adapt to the adjustment requirements of the pump base 400 in the narrow installation space A.

[0036] The upper connecting part 303 is arranged in the horizontal direction. The upper connecting part 303 is welded to the top of the jack 200. The weld is a continuous weld to ensure the firmness of the connection. The weld undergoes strict quality inspection, including visual inspection and non-destructive testing, to ensure that the welding quality meets the design requirements.

[0037] The middle connecting part 302 is arranged in the vertical direction. The middle connecting part 302 serves to connect the lower connecting part 301 and the upper connecting part 303, and at the same time provides installation space for the telescopic structure. The length of the middle connecting part 302 can be designed according to actual usage requirements, ensuring smooth operation in a narrow space while providing sufficient adjustment range.

[0038] The lower connecting part 301 is arranged in the horizontal direction. The length and width of the lower connecting part 301 are precisely calculated so that it can extend exactly below the exposed part 401 of the pump base 400 and can stably support the edge. Furthermore, the edge of the lower connecting part 301 is rounded to avoid damage to the edge of the exposed part 401 during operation.

[0039] The Z-shaped steel connecting component 300 is firmly welded to the top of the jack 200, ensuring that there will be no loosening or slippage during the transmission of lifting force. Its lower part can extend below the edge of the channel steel pump base 400, so that when adjusting the elevation of the circulating pump, the force can be precisely applied to the pump base 400. It is convenient for technicians to operate. They can accurately adjust the pump elevation by simply controlling the lifting or lowering of the jack 200. The connecting component 300 fully considers the limitations of narrow space and can play a maximum role in a limited space, providing technicians with an efficient and convenient means of adjustment.

[0040] For the specific construction of the vertically adjustable connecting portion 302, see [link to relevant documentation]. Figure 2 The middle connecting portion 302 includes a first connecting member 3021 and a second connecting member 3022 arranged sequentially from top to bottom. Both the first connecting member 3021 and the second connecting member 3022 are arranged vertically. Both the first connecting member 3021 and the second connecting member 3022 have a plurality of limiting holes 30221, which are arranged at intervals along the vertical direction. The limiting holes 30221 on the first connecting member 3021 and the limiting holes 30221 on the second connecting member 3022 correspond to each other. The limiting holes 30221 are configured to accommodate limiting bolts 3023. By providing multiple insertable limiting bolts in the middle connecting portion 302 of the connecting member 300, a plurality of insertable limiting bolts are achieved. The limiting hole 30221 of bolt 3023 allows for adjustment of the overall length of connecting component 300 by adjusting the position of the limiting bolt 3023 in different limiting holes 30221. Furthermore, the limiting bolt 3023 is made of high-strength alloy steel, possessing good strength and wear resistance. When it is necessary to adjust the length of connecting component 300, the limiting bolt 3023 is loosened, the middle connecting part 302 in connecting component 300 is adjusted to a suitable length, and then the limiting bolt 3023 is inserted into the corresponding limiting hole 30221 and tightened. The tightening force of the limiting bolt 3023 is moderate, ensuring that the connecting component 300 does not loosen during operation, while also avoiding damage to the component due to excessive tightening force.

[0041] The limiting bolt 3023 is a key component for achieving precise adjustment. The limiting bolt 3023 can precisely adjust the length of the connecting component 300 according to actual needs, enabling technicians to flexibly handle pump bases 400 of different heights and achieve fine adjustment of the pump elevation. During operation, technicians only need to loosen the limiting bolt 3023, adjust the connecting component 300 to the appropriate length, and then tighten the limiting bolt 3023 to fix it. The design of the limiting bolt 3023 not only improves the adjustment accuracy but also enhances the versatility of the device, making it adaptable to pump bases 400 of different specifications of desulfurization liquid circulation pumps.

[0042] See Figure 1 The bottom of the installation space A is provided with a support platform 500, and the upper end of the support platform 500 is provided with a rigid support member 600. The upper end surface of the rigid support member 600 is horizontal, and the upper end surface of the rigid support member 600 supports and connects the jack 200.

[0043] Specifically, the pier 500 is made of concrete, and the rigid support 600 is also made of high-quality alloy steel. The alloy steel and the connecting component 300 are made of the same material, which has extremely high strength and corrosion resistance. It can be used stably for a long time in harsh factory environments, such as high temperature, high humidity, and corrosive gases. In addition, it can ensure the material consistency and performance matching of the entire device. The thickness of the rigid support 600 is selected according to the load-bearing capacity of the jack 200 and the operating environment, and is generally between a few centimeters and a dozen centimeters. In this embodiment, the rigid support 600 is a square plate structure.

[0044] Furthermore, the surface of the rigid support 600 is flattened, and the opposite sides of the rigid support 600 and the support platform 500 are fitted together to ensure that the contact surface of the rigid support 600 and the support platform 500 is subjected to uniform force and improves stability.

[0045] Furthermore, the corners of the rigid support 600 are all rounded, that is, the corners of the rigid support 600 are all rounded, to avoid injury to personnel during operation.

[0046] Furthermore, the rigid support 600 is firmly connected to the base of the jack 200 by welding. The welding adopts a continuous weld, and strict quality inspection is carried out after the welding is completed to ensure that the welding strength can withstand the pressure generated by the jack 200 during operation.

[0047] To improve the stability of the connection, a reinforcing rib is provided on the outer periphery of the connection between the rigid support 600 and the jack 200. The reinforcing rib, the jack 200 and the rigid support 600 are made of the same material. Optionally, the reinforcing rib is fixed between the rigid support 600 and the jack 200 by welding or bolting.

[0048] By adding a rigid support member 600 welded between the base of the jack 200 and the foundation 500, the rigid support member 600 enhances stability. The rigid support member 600 increases the contact area of ​​the concrete foundation 500, allowing the jack 200 to be placed more stably on the foundation 500 during operation. When the jack 200 is lifted, the rigid support member 600 can evenly distribute the reaction force on the jack 200 onto the concrete foundation 500, effectively preventing the jack 200 from tipping over due to uneven force. For technicians, operation is safer and more reliable, and there is no need to worry about instability during the adjustment process.

[0049] Force transmission path:

[0050] When the operator operates the jack 200, the lifting force of the jack 200 is transmitted to the upper connecting part 303 of the connecting member 300 through the jack head. Due to the strong welded connection between the jack head and the upper connecting part 303, the lifting force of the jack 200 can be smoothly transmitted to the connecting member 300.

[0051] The connecting member 300 transmits force to the lower connecting part 301 in the connecting member 300. The lower connecting part 301 abuts against the exposed part 401 of the pump base 400, transmitting force to the pump base 400 below the slurry circulation pump 100, thereby adjusting the elevation of the pump base 400 below the slurry circulation pump 100.

[0052] During the adjustment process, the rigid support 600 maintains stable contact with the concrete foundation 500, distributing the reaction force of the jack 200 to the concrete foundation 500 and ensuring the stability of the entire device.

[0053] Collaborative working mechanism:

[0054] According to actual needs, the operator can adjust the elevation of the pump base 400 below the slurry circulation pump 100 by controlling the lifting or lowering of the jack 200. During the adjustment process, the position and status of the connecting component 300 must be closely observed to ensure that the lower connecting part 301 can accurately abut against the exposed part on the pump base 400.

[0055] The length of the connecting component 300 can be adjusted by adjusting the position of the limit bolt 3023 to meet different adjustment requirements. When adjusting the limit bolt 3023, attention should be paid to the safety and accuracy of the operation to avoid damage to the device and the pump base 400 below the slurry circulation pump 100.

[0056] The rigid support 600 plays a stabilizing role throughout the adjustment process, ensuring that the jack 200 will not tip over due to uneven force. At the same time, the operator also needs to regularly check the contact between the rigid support 600 and the concrete foundation 500 to ensure that the contact area is uniform and the stability is good.

[0058] S1. Preparations

[0059] Inspect all components of the device: Confirm that the jack 200, connecting component 300, rigid support component 600, and limit bolt 3023 are intact and undamaged, with no obvious deformation, cracks, or corrosion.

[0069] After adjustment, tighten the limit bolt 3023 to fix the length of the connecting component 300;

[0070] S4. Elevation Adjustment

[0071] Operators use manual levers or electric controllers to operate jack 200 for lifting or lowering operations.

[0072] Observe the elevation change of the desulfurization pump base 400, and at the same time pay attention to the position and status of the connecting component 300, ensuring that its lower part always presses against the exposed part 401 of the pump base 400;

[0073] As needed, gradually adjust the lifting height of jack 200 until the desulfurization pump base 400 reaches the required elevation accuracy;

[0074] S5. Inspection and Fixation

[0075] After the elevation adjustment of the desulfurization pump base 400 is completed, check the connection and stability of each component of the device again;

[0076] After confirming that everything is correct, lock the jack 200 to prevent it from moving accidentally during operation, and then reinforce the base of the jack 200.

[0077] Check the installation of the desulfurization slurry circulation pump 100 to ensure that its levelness and stability meet the requirements;

[0078] S6. Dismantling device

[0079] Once the desulfurization slurry circulation pump 100 is installed and the pump base 400 is fixed, this elevation adjustment device can be removed.

[0080] First, loosen the locking device of jack 200 and slowly lower jack 200 to separate connecting component 300 from desulfurization pump base 400.

[0081] Store all parts properly for future use.
