Description

Technical Field

[0001] The utility model relates to the technical field of shear pumps, in particular to a shear pump assembly and a shear pump. Background Technique

[0002] Through the high-speed movement generated by the rotor, the shear pump promotes the flow of liquid between the rotor and the stator. Through the friction and shear action, the liquid is evenly refined and mixed. It is suitable for processing fluids with various viscosities, especially in cases where high shear force is required, such as emulsification, dispersion, and homogenization;

[0003] When the pump housing of the existing shear pump assembly is connected to the external pipeline, a connecting flange is usually used for connection. When material leakage occurs at the connection between the connecting flange and the external pipeline and the material is ejected in a small range, it is usually not easy for the operator to detect it in time. Therefore, the operator cannot repair the leakage in time, which affects the normal use of the shear pump. For this reason, we propose a shear pump assembly and a shear pump. Content of the Utility Model

[0004] The purpose of the utility model is to provide a shear pump assembly and a shear pump to solve the problem that it is not easy for the operator to detect material leakage in time as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A shear pump assembly, comprising:

[0006] A support frame, on the top of the support frame is provided a pump body, on the side wall of the pump body is provided a pump housing, and at the input end of the pump housing is provided a connecting flange;

[0007] A metal ring, which is fitted outside the connecting flange. Inside the metal ring is provided a sliding ring, on the side wall of the sliding ring is provided a locking piece, on the side wall of the metal ring is provided a support ring, on the circumferential inner wall of the support ring is provided a sensor belt, the sensor belt is electrically connected to a data processor, and the data processor is electrically connected to a buzzer;

[0008] A liquid storage tank, which is arranged at the bottom of the support ring. On the top of the liquid storage tank is provided a rubber sheet, on the side wall of the rubber sheet is provided a retaining post, the side wall of the retaining post is fitted with a locking member, and on the side wall of the rubber sheet is provided a round hole.

[0009] Preferably, a plurality of support columns are arranged between the metal ring and the sliding ring.

[0010] Preferably, the data processor is embedded in the side wall of the support frame.

[0011] Preferably, the rubber sheet is fitted on the side wall of the support ring.

[0012] Preferably, the sensor belt is fitted to the outside of the connecting flange.

[0013] Preferably, a notch adapted to the liquid storage tank is formed at the bottom of the support ring.

[0014] Preferably, a locking bolt is provided on the side wall of the locking member.

[0015] A shear pump includes the aforementioned shear pump assembly.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. By providing a support ring with a sensor belt on the outside of the connecting flange, the present utility model enables the support ring to slide through the sliding ring of the metal ring. When material leakage occurs at the connection between the connecting flange and the external pipeline, the sensor belt is impacted by the leaked high-pressure material and transmits the pressure data to the data processor, and then the data processor turns on the buzzer for beeping warning. It can give a timely beeping warning when leakage occurs at the connecting flange, so that the staff can discover the leakage in time and carry out timely maintenance.

[0018] 2. When material leakage occurs and the material impacts the outside of the sensor belt, the rubber sheet blocks the side wall of the support ring. At this time, after the material flows downward, it can enter the inside of the liquid storage tank through the notch. Thus, when material leakage occurs, the support ring and the rubber sheet can block the leaked material and collect it inside the liquid storage tank, avoiding the pollution of the equipment caused by the splashing of the material everywhere and facilitating the operator to clean the leaked material.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment

[0026] Please refer to Figures 1-4 , a shearing pump assembly shown in the figure, including:

[0027] A pump machine 110 is arranged at the top of the support frame 100. A pump shell 111 is arranged on the side wall of the pump machine 110. A connecting flange 120 is arranged at the input end of the pump shell 111, and a discharge joint is arranged at the output end of the pump shell 111;

[0028] A metal ring 200 is fitted outside the connecting flange 120. A sliding ring 201 is arranged inside the metal ring 200. The sliding ring 201 is sleeved outside the pipe part of the connecting flange 120. A locking piece 202 is arranged on the side wall of the sliding ring 201. A bolt is arranged on the side wall of the locking piece 202. When the bolt is tightened, the position of the sliding ring 201 can be locked by cooperating with the outer wall of the pipe part of the connecting flange 120. A support ring 210 is arranged on the side wall of the metal ring 200. A sensor belt 211 is arranged on the inner wall of the circumference of the support ring 210. The sensor belt 211 uses a common thin-film pressure sensor on the market. The structure of the thin-film pressure sensor usually consists of a flexible film, a sensitive element and its encapsulation, forming a system that converts external pressure into an electrical signal. The thin-film pressure sensor accurately measures pressure by using the deformation or change in electrical characteristics generated by the thin-film material under the pressure of material impact. The sensor belt 211 is electrically connected to a data processor 220. The data processor 220 uses a common model on the market. The data processor consists of an input interface, a processing unit, a storage unit and an output interface. Its working principle is to first receive information from the sensor belt 211, perform calculations and analyses through the processing unit, store the results in the storage unit, and finally control a buzzer 221 to beep through the output interface. The data processor 220 is electrically connected to the buzzer 221. The buzzer 221 uses a common model on the market. It usually drives an internal vibrating membrane or piezoelectric material through an electric current to generate an audio signal;

[0029] The liquid storage tank 300 is arranged at the bottom of the support ring 210. A rubber sheet 310 is arranged at the top of the liquid storage tank 300. A retaining post 320 penetrating through the top of the liquid storage tank 300 is arranged on the side wall of the rubber sheet 310. A locking member 321 is engaged with the side wall of the retaining post 320. A round hole 311 is formed in the side wall of the rubber sheet 310. The rubber sheet 310 is provided with a slit matching the round hole 311. When the external pipeline and the connecting flange 120 are connected, the rubber sheet 310 can be first pulled to sleeved on the outside of the external pipeline in cooperation with the round hole 311, and then the retaining post 320 can be slid upward to block the side wall of the rubber sheet 310, so that the rubber sheet 310 fits on the side wall of the support ring 210.

[0030] Specifically, a plurality of support columns are arranged between the metal ring 200 and the sliding ring 201.

[0031] Further, the data processor 220 is embedded in the side wall of the support frame 100.

[0032] Furthermore, the rubber sheet 310 fits on the side wall of the support ring 210.

[0033] Furthermore, the sensor belt 211 fits on the outside of the connecting flange 120.

[0034] It should be noted that a notch 301 matching the liquid storage tank 300 is formed at the bottom of the support ring 210.

[0035] It should be noted that a locking bolt is arranged on the side wall of the locking member 321. Tightening the locking bolt can press the retaining post 320 to lock the position of the retaining post 320.

[0036] The present utility model also provides a shearing pump, including the aforementioned shearing pump assembly.

[0037] In addition, the aforementioned electrical components and electrical equipment all use an external power supply. The circuits, electronic components and modules involved in the present utility model are all prior arts, which can be fully realized by those skilled in the art without further elaboration. The content protected by the present utility model does not involve improvements to the internal structure and method either;

[0038] Working principle: By arranging a support ring 210 with a sensor strip 211 outside the connecting flange 120, the support ring 210 can be slid by the sliding ring of the metal ring 200. When material leakage occurs at the connection between the connecting flange 120 and the external pipeline, the sensor strip 211 is impacted by the leaked high-pressure material and transmits the pressure data to the data processor 220. Then, the data processor 220 turns on the buzzer 221 for beeping warning, which can give a timely beeping warning when leakage occurs at the connecting flange 120, so that the staff can discover the leakage in time and carry out timely maintenance. When material leaks and the material impacts outside the sensor strip 211, the rubber sheet 310 blocks the side wall of the support ring 210. At this time, after the material flows downward, it can enter the inside of the liquid storage tank 300 through the notch 301. Thus, when material leaks, the support ring 210 and the rubber sheet 310 can block the leaked material and collect it inside the liquid storage tank 300, preventing the material from splashing everywhere and causing pollution to the equipment, and facilitating the operator to clean the leaked material.
