Description

Technical Field

[0001] This utility model belongs to the field of plunger pump technology, specifically, it relates to a single-cylinder sludge plunger pump. Background Technology

[0002] A single-cylinder sludge plunger pump is a commonly used device, mainly used to transport liquids containing sludge. Its working principle is to generate a pressure difference through the reciprocating motion of the piston in the pump body, thereby realizing the intake and discharge of sludge.

[0003] During the use of existing single-cylinder sludge plunger pumps, on the one hand, due to the lack of an effective mechanism for handling lumpy sludge, lumpy sludge is prone to accumulate in the input pipe or pump body, leading to pipe blockage and pump damage, affecting the normal operation of the equipment, reducing work efficiency, and increasing maintenance costs and downtime.

[0004] On the other hand, iron impurities in the sludge will enter the pump body along with the sludge, causing wear on the piston, seals and other components inside the pump body, and shortening the service life of the equipment. In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a single-cylinder sludge plunger pump that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A single-cylinder sludge plunger pump includes a base plate and further includes: a pump body fixedly connected to the base plate; a piston slidably connected to the pump body, wherein an input pipe and an output pipe are fixedly connected to the pump body, and an anti-clogging tank is provided in the middle section of the input pipe; a sealing cover detachably connected to the anti-clogging tank; a rotating shaft rotatably connected to the sealing cover and located in the anti-clogging tank; and multiple sets of crushing blades fixedly connected at equal intervals on the rotating shaft, wherein each set of crushing blades has multiple blades, and the multiple crushing blades are circumferentially distributed at equal intervals on the rotating shaft, and magnetic blocks are embedded in the upper and lower end faces of each crushing blade.

[0008] Preferably, it also includes a filter screen, which is disposed inside the output end of the input pipe and is used to block clumps of sludge in the anti-clogging tank.

[0009] In order to drive the rotating shaft to rotate, preferably, a micro motor is fixedly installed on the sealing cover, and the rotating shaft is fixedly connected to the output end of the micro motor.

[0010] To facilitate the installation and removal of the sealing cap, preferably, multiple fixing bolts are also included, and the sealing cap is detachably connected to the anti-clogging tank through multiple fixing bolts.

[0011] For driving the piston to reciprocate up and down within the pump body, preferably, a guide rod is fixedly connected to the pump body, a base is fixedly connected to the upper end of the guide rod, a sliding seat is slidably connected to the guide rod, the piston is fixedly connected to the lower end face of the sliding seat, a hydraulic telescopic rod is fixedly connected to the base, and the telescopic end of the hydraulic telescopic rod is fixedly connected to the upper end face of the sliding seat.

[0012] To improve the overall stability of the pump body, preferably, both ends of the base plate are symmetrically fixedly connected with screw sleeves, the screw sleeves are internally threaded with screw rods, the upper end of the screw rods is fixedly connected with a handle, and the lower end is fixedly connected with a balance base.

[0013] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0014] This utility model features an anti-clogging tank in the middle of the inlet pipe, containing a high-speed rotating crusher that can cut and crush the incoming lumpy sludge. At the same time, a filter screen is installed at the outlet to intercept incompletely crushed lumpy sludge, allowing it to be continuously crushed. These multiple measures effectively prevent sludge from clogging the pump body and pipeline, ensuring stable operation of the equipment.

[0015] The crushing blade has embedded magnetic blocks that rotate with it, expanding the adsorption range and efficiently adsorbing iron impurities in the sludge. This reduces the amount of impurities entering the pump body, lowers the risk of wear on internal pump components caused by iron impurities, and extends the service life of the equipment.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0023] Example 1:

[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A single-cylinder sludge plunger pump includes a base plate 1 and further includes: a pump body 2, fixedly connected to the base plate 1; a piston 201, slidably connected to the pump body 2, wherein an input pipe 202 and an output pipe 203 are fixedly connected to the pump body 2, and an anti-clogging tank 4 is provided in the middle section of the input pipe 202; a sealing cover 401, detachably connected to the anti-clogging tank 4; a rotating shaft 5, rotatably connected to the sealing cover 401 and located in the anti-clogging tank 4; and multiple sets of crushing blades 501, equidistantly fixedly connected to the rotating shaft 5, wherein each set of crushing blades 501 is provided with multiple blades, and the multiple crushing blades 501 are circumferentially distributed on the rotating shaft 5, and magnetic blocks 502 are embedded in the upper and lower end faces of the crushing blades 501.

[0025] It also includes a filter screen 504, which is located inside the output end of the input pipe 202 and is used to block clumps of sludge in the anti-clogging tank 4.

[0026] A micro motor 503 is fixedly installed on the sealing cover 401, and the rotating shaft 5 is fixedly connected to the output end of the micro motor 503.

[0027] A guide rod 301 is fixedly connected to the pump body 2. A base 3 is fixedly connected to the upper end of the guide rod 301. A sliding seat 303 is slidably connected to the guide rod 301. The piston 201 is fixedly connected to the lower end face of the sliding seat 303. A hydraulic telescopic rod 302 is fixedly connected to the base 3. The telescopic end of the hydraulic telescopic rod 302 is fixedly connected to the upper end face of the sliding seat 303.

[0028] In use, the power supply to the micro motor 503 and the hydraulic telescopic rod 302 is turned on. After the micro motor 503 starts, it drives the rotating shaft 5 to rotate, thereby causing the multiple sets of crushing blades 501 fixed on the rotating shaft 5 to rotate at high speed. When sludge enters the anti-clogging tank 4 from the input pipe 202, the lumpy sludge in it will be cut and crushed by the rotating crushing blades 501. At the same time, the magnetic blocks 502 on the crushing blades 501 will adsorb iron impurities in the sludge. Meanwhile, the magnetic blocks 502 that rotate with the crushing blades 501 expand the adsorption range, enabling them to more comprehensively clean the sludge in the anti-clogging tank 4. The adsorption of iron impurities greatly improves the adsorption efficiency of iron impurities, reduces the possibility of iron impurities entering the pump body 2, and further reduces the risk of wear of internal components of the pump body 2 due to iron impurities, thereby extending the service life of the equipment. Then, the crushed sludge continues to flow in the input pipe 202. When it reaches the output end of the input pipe 202, the filter screen 504 will block the sludge that is not completely crushed and has clumped into blocks in the anti-clogging tank 4, so that it continues to contact the crushing blade 501 for further crushing until the sludge particle size meets the requirements before it can pass through the filter screen 504 and enter the pump body 2.

[0029] At this time, the hydraulic telescopic rod 302 starts to work. When its telescopic end retracts, it pulls the sliding seat 303 to slide upward on the guide rod 301. When the sliding seat 303 slides upward, the piston 201 moves upward accordingly. At this time, a negative pressure is formed in the pump body 2. The filtered sludge is sucked into the pump body 2 from the input pipe 202. When the telescopic end of the hydraulic telescopic rod 302 extends, it pushes the sliding seat 303 to slide downward on the guide rod 301. The piston 201 also moves downward, squeezing the sludge in the pump body 2 out of the output pipe 203.

[0030] It should be noted that both the input pipe 202 and the output pipe 203 are equipped with one-way valves.

[0031] In summary, by installing an anti-clogging tank 4 in the middle section of the input pipe 202, which contains a high-speed rotating crusher 501, the incoming blocky sludge can be cut and crushed. At the same time, a filter screen 504 is installed at the output end to intercept incompletely crushed blocky sludge, so that it can be continuously crushed. Multiple measures effectively prevent sludge from clogging the pump body and pipeline, ensuring stable operation of the equipment.

[0032] The crusher blade 501 has an embedded magnetic block 502 that rotates with it, expanding the adsorption range and efficiently adsorbing iron impurities in the sludge. This reduces the amount of impurities entering the pump body 2, lowers the risk of wear on the internal components of the pump body 2 caused by iron impurities, and extends the service life of the equipment.

[0033] Example 2:

[0034] Reference Figure 3 , Figure 4A single-cylinder sludge plunger pump, which is basically the same as in Embodiment 1, further includes multiple fixing bolts 402, and the sealing cover 401 is detachably connected to the anti-clogging tank 4 through the multiple fixing bolts 402.

[0035] When the equipment is running normally, the sealing cover 401 is firmly installed on the anti-blocking tank 4 by the fixing bolt 402, which plays the role of sealing the anti-blocking tank 4 and ensuring the normal operation of internal components such as the rotating shaft 5 and the crushing blade 501;

[0036] When it is necessary to clean, repair or replace parts inside the anti-clogging tank 4, for example, when the breaker blade 501 is severely worn and needs to be replaced, the sealing cover 401 can be opened by removing the fixing bolts 402, so that the operator can perform the relevant operations.

[0037] In summary, using fixing bolts 402 to detach and connect the sealing cap 401 and the anti-blocking tank 4 is a simple and reliable method that ensures the sealing and stability of the anti-blocking tank 4 during operation, facilitates subsequent maintenance and repair, reduces maintenance costs, and improves the maintainability and service life of the equipment.

[0038] Example 3:

[0039] Reference Figure 1 , Figure 2 A single-cylinder sludge plunger pump is basically the same as in Embodiment 1. Furthermore, both ends of the base plate 1 are symmetrically fixedly connected with screw sleeves 101, and screw sleeves 101 are internally threaded to screw rods 102. The upper end of the screw rod 102 is fixedly connected to a handle 104, and the lower end is fixedly connected to a balance base 103.

[0040] Once the equipment is placed on the ground, if it is necessary to adjust the level or balance of the equipment, the operator holds the handle 104 and turns it clockwise or counterclockwise. When the handle 104 is turned clockwise, the screw 102 rotates downward within the screw sleeve 101, and the balance base 103 descends accordingly. When the handle 104 is turned counterclockwise, the screw 102 rotates upward, and the balance base 103 rises accordingly. By adjusting the height of the screws 102 at both ends of the base plate 1, the equipment can be gradually brought to a level state. During the adjustment process, a level should be used continuously for detection and fine-tuning to ensure that the level or balance of the equipment meets the requirements.

[0041] In summary, by providing screw sleeves 101, screws 102, handles 104, and balance bases 103 at both ends of the base plate 1, the levelness and balance of the equipment can be easily adjusted, thereby helping the equipment to maintain stable operation under different ground conditions, reducing component wear and operational failures caused by equipment shaking or tilting, and improving the stability of the equipment.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
