At the same time, it also has extremely high research value and significance in food processing and other aspects;

[0003] However, today's axial flow pumps and slurry pumps are improved designs from previous clean water pumps and can only filter small solid particles (less than 20mm) or be used for thick liquids, which makes the existing pumps have a single use case;

[0004] It is difficult to handle more complex transport objects. In production and life, the transported objects may be more than a single object, and there may be more complex scenes with multiple objects coexisting, such as solid-liquid two-phase state. Taking dredging engineering as an example, complex scenes include: mud, sewage, clothes, stones, plastic bottles and other transported objects;

[0005] Ordinary pump bodies have low working efficiency during dredging activities, have few ways to deal with complex scenarios, and will also hinder the continued processing and production of industrial production scenarios. At the same time, it is even more difficult to handle long fiber tissues, and may even cause damage to the pump body, seriously affecting its normal use.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original conveying pump structure. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In this embodiment, Figure 1-Figure 5 The specific contents are as follows:

[0029] A water suction chamber 1 and a pump body 3 fixedly installed on the right side of the water suction chamber 1;

[0030] A pump cover 4 is fixedly installed at one end of the pump body 3 away from the water absorption chamber 1, a fixed suspension 11 is fixedly installed at one side of the pump cover 4 away from the pump body 3, and a plug 16 is fixedly installed at the lower end of the water absorption chamber 1, and the plug 16 can prevent water from entering the pump body 3;

[0031] The pump cover 4 is provided with sealing gaskets 5 on both sides close to the water suction chamber 1 and the pump body 3, and the impeller 2 is rotatably installed inside the pump cover 4, and the impeller 2 is located inside the water suction chamber 1 and the pump body 3 at the same time;

[0032] A rear end shaft 12 is mounted on the right side of the impeller 2 and is rotatably mounted inside the fixed suspension 11 . An end of the rear end shaft 12 away from the impeller 2 is located outside the fixed suspension 11 and can be supported by the fixed suspension 11 .

[0033] When using the new large-particle long-fiber spiral centrifugal delivery pump, the delivery pump needs to be fixed at the position where it needs to work, and then the right side of the rear end shaft 12 can be docked with the driving device, so that the driving device drives the impeller 2 to rotate at a high speed through the rear end shaft 12;

[0034] The fluid is sucked into the water suction chamber 1 under the action of the high-speed rotating impeller 2. The impeller 2 is composed of two parts, the spiral section and the centrifugal section. The spiral section provides a positive displacement thrust. This force forms a bending component in the axial extension, so that the water flow at the inlet flows along the tangential direction of the impeller 2, rather than being sucked into the pump chamber at a right angle to the impeller 2. The impeller 2 is composed of two parts, the spiral section and the centrifugal section. The spiral section provides a positive position instead of entering the pump body 3 at a right angle or at a certain angle to the impeller 2. The axial thrust of the spiral section makes the water flow out smoothly until the centrifugal section, and then the centrifugal section pushes the water flow to be discharged from the outlet, thereby completing the use process of the centrifugal delivery pump, thereby effectively expanding the scope of application of the delivery pump.

[0035] During the river channel dredging construction, first connect the pump body 3 with the sewage pipe and the suction pipe, then put the suction pipe into the river channel sludge to be operated, and then connect the driving device that has been connected to the centrifugal pump to the power supply. At this time, start the spiral centrifugal delivery pump and make the spiral centrifugal delivery pump start working. The debris in the river channel (such as stones, towels, etc.) is sucked into the water absorption chamber 1 through the suction pipe. The debris is transported to the sewage outlet and discharged with the help of the impeller 2. After entering the sewage pipe, it is sent to the subsequent process for processing. The spiral centrifugal pump works continuously until the debris under the river channel is pumped out, and then the pump can be taken out for cleaning and maintenance for reuse.

[0036] Based on the embodiment, it is worth mentioning that, as shown in FIG. Figure 1 and Figure 4 As shown:

[0037] The outer side of the rear end shaft 12 is sleeved with a stopper sleeve 7, and the stopper sleeve 7 is located inside the pump cover 4, and the outer side of the stopper sleeve 7 is sleeved with an O-type sealing ring 6, and the O-type sealing ring 6 is nested inside the pump cover 4, and the stopper sleeve 7 can be used to buffer and protect the rear end shaft 12 and the pump cover 4;

[0038] The outer side of the stopper sleeve 7 is provided with a mechanical seal sleeve 9, and the mechanical seal sleeve 9 is located on the right side of the O-ring 6. The outer side of the stopper sleeve 7 is provided with two sets of shaft sleeves 8, and the two sets of shaft sleeves 8 are located on the inner and outer sides of the mechanical seal sleeve 9. Through the cooperation between the O-ring 6, the stopper sleeve 7, the shaft sleeve 8 and the mechanical seal sleeve 9, the sealing effect between the pump cover 4 and the rear end shaft 12 can be effectively guaranteed;

[0039] Bearing caps 14 are fixedly installed on both sides of the fixed suspension 11, and a suspension bracket 15 is rotatably installed on the lower end of the fixed suspension 11 away from the water absorption chamber 1. Two sets of deep groove ball bearings 13 are nested and installed inside the fixed suspension 11, and the deep groove ball bearings 13 and the bearing caps 14 are located on the outside of the rear end shaft 12, and the two sets of deep groove ball bearings 13 are located between the two sets of bearing caps 14, so that the centrifugal pump can be conveniently taken through the suspension bracket 15 for operation, and the two sets of deep groove ball bearings 13 can be protected by the bearing caps 14 to prevent the deep groove ball bearings 13 from being damaged by impurities entering the deep groove ball bearings 13;

[0040] A water retaining ring 10 is provided on the outer side of the rear end shaft 12, and the water retaining ring 10 is located inside the bearing cover 14. The water retaining ring 10 is located inside the bearing cover 14. The internal sealing effect of the fixed suspension 11 can be completed through the cooperation of the bearing cover 14 and the water retaining ring 10, thereby increasing the overall practicality.
