Description

Technical Field

[0001] This utility model belongs to the field of pump head unblocking technology, and in particular relates to an auxiliary device for unblocking screw pump heads. Background Technology

[0002] A screw pump is a rotary pump that moves fluid by rotating a screw. This type of pump is designed to handle a variety of fluids, including high-viscosity fluids, fluids containing solid particles, and shear-sensitive fluids. It is widely used in civil and industrial construction fields such as high-rise buildings, municipal construction, power, energy, and transportation, where large quantities of concrete and mortar are required, high strength, strict quality requirements, and long transportation distances are needed. However, screw pumps often encounter the following problems in practical applications:

[0003] 1. Due to the varying levels of professional expertise among operators, the screw pump head is prone to blockage during construction operations;

[0004] 2. Due to unstable working environments such as new or renovated projects, sudden power outages, equipment failures, etc., the screw pump cannot be used and cannot be cleaned in time, resulting in blockage of the pump head.

[0005] like Figure 2 As shown, the screw pump head includes a stator 100 (outer shell) and a rotor 200 installed inside the stator 100, with one end of the rotor extending out of the stator. When the screw pump head is blocked, the traditional method of unblocking is to use a chuck to fix the stator, then use pipe wrenches to clamp the extended end of the rotor, and manually use brute force to rotate the rotor out little by little. After the rotor is removed, the stator and rotor are cleaned and reinstalled to complete the unblocking. This unblocking method requires a lot of manual labor and is time-consuming and laborious when removing the rotor, so an auxiliary device needs to be designed. Utility Model Content

[0006] The main objective of this invention is to provide an auxiliary device for unblocking screw pump heads, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An auxiliary device for unblocking the pump head of a screw pump includes an upper baffle, a middle baffle, and a lower baffle. At least three screws are inserted through the upper, middle, and lower baffles. The middle and lower baffles are fixedly connected to the screws. The upper baffle is detachably fixed to the screws by nuts. There is one nut at the top and one at the bottom of the upper baffle. A jack is fixed on the lower baffle. A first hole is opened in the middle of the middle baffle, through which the output shaft of the jack passes. A second hole is opened in the middle of the upper baffle.

[0009] Preferably, the upper baffle, middle baffle, and lower baffle are all made of 2cm thick round steel plates.

[0010] Preferably, the upper baffle, middle baffle, and lower baffle have a diameter of 20-22 cm, the first hole has a diameter of 5-10 cm, and the second hole has a diameter of 8-12 cm.

[0011] Preferably, the screw has a diameter of 8-12 mm and a total length of 150 cm.

[0012] This utility model provides an auxiliary device for unblocking the pump head of a screw pump, which has the following beneficial effects:

[0013] This invention fixes the clogged screw pump head between the middle baffle and the upper baffle, then uses a jack to push out the rotor of the pump head, cleans the stator and rotor, and reinstalls it to unclog the pump head and put it into reuse. Compared with traditional unclogging methods, this invention reduces the intensity of manual labor, saves more time and effort, and is convenient and quick. Attached Figure Description

[0021] Example

[0022] Reference Figure 1-2 An auxiliary device for unblocking the pump head of a screw pump includes an upper baffle 1, a middle baffle 3, and a lower baffle 5. At least three screws 4 are inserted through the upper baffle 1, the middle baffle 3, and the lower baffle 5. The middle baffle 3 and the lower baffle 5 are fixedly connected to the screws 4. The upper baffle 1 is detachably fixedly connected to the screws 4 by nuts 2. There is a nut 2 at the top and a nut 2 at the bottom of the upper baffle 1. A jack is fixed on the lower baffle 5. A first hole 6 is opened in the middle of the middle baffle 3. The output shaft of the jack passes through the first hole 6. A second hole 7 is opened in the middle of the upper baffle 1.

[0023] This utility model also provides a method for using an auxiliary device for unblocking screw pump heads, comprising the following steps:

[0024] S1. Unscrew the nut 2 that secures the upper baffle 1 and remove the upper baffle 1;

[0025] S2. Place the clogged screw pump head on the middle baffle 3 with the extended end of the rotor facing upwards;

[0026] S3. Re-attach the upper baffle 1 onto the screw 4 so that the extended end of the rotor is located in the second hole. Then tighten the nut 2 to clamp the stator 100 between the upper baffle 1 and the middle baffle 3.

[0027] S4. Start the jack. The output shaft of the jack will push the rotor 200 out of the stator 100. During the pushing process, you can use your hand to assist in rotating the rotor. After the rotor is pushed out, clean the stator and rotor, reinstall them, and the unblocking is completed.

[0028] This invention fixes the clogged screw pump head between the middle baffle 3 and the upper baffle 1, then uses a jack to push out the rotor of the pump head, cleans the stator and rotor, and reinstalls it to unclog the pump head and put it into secondary use.

[0030] In one specific implementation, the upper baffle 1, the middle baffle 3, and the lower baffle 5 are all 2cm thick round steel plates.

[0031] In one specific implementation, the upper baffle 1, the middle baffle 3 and the lower baffle 5 have a diameter of 20-22cm, the first hole 6 has a diameter of 5-10cm, and the second hole 7 has a diameter of 8-12cm.
