Description

Technical Field

[0001] The utility model relates to the technical field of pipeline pumps, in particular to a vertical pipeline pump capable of preventing blockage. Background Art

[0002] Vertical pipeline pumps are mainly used for industrial and urban water supply and drainage, high-rise building pressurized water supply, garden sprinkler irrigation, fire fighting pressurization, long-distance transportation, HVAC refrigeration cycle, bathroom and other hot and cold water circulation pressurization and equipment matching.

[0003] The existing vertical pipeline pump generally only adds a filter screen to prevent clogging of the vertical pipeline pump.

[0004] However, the vertical pipeline pump in the prior art filters impurities by adding a filter. Since the filter is mostly arranged in a plane at the inlet end and is in the channel where the water flows, it is impossible to separate the impurities and the water, which leads to the accumulation of impurities on the surface of the filter. When a large amount of foreign matter accumulates on the filter, the working efficiency of the vertical pipeline pump will be greatly affected. The pump can only be manually shut down and disassembled for cleaning. However, frequent cleaning will increase the maintenance cost of the vertical pipeline pump. In view of this, we propose a vertical pipeline pump that prevents blockage. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a vertical pipeline pump that prevents clogging, so as to solve the technical problem that the current vertical pipeline pump filters impurities by adding a filter screen. Since the filter screen is mostly arranged in a plane at the inlet end in the channel where the water flows, it is impossible to separate the impurities and the water body, which leads to the accumulation of impurities on the surface of the filter screen, affecting the working efficiency of the vertical pipeline pump and increasing the maintenance cost of the vertical pipeline pump.

[0006] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a vertical pipeline pump that prevents blockage, including a pipeline pump and a motor installed on the pipeline pump;

[0007] The pipeline pump has an output end and an input end, and a filter assembly for filtering water is detachably mounted on one end of the input end, the filter assembly includes an upper shell, a lower shell is detachably mounted on the bottom end of the upper shell, and an input pipe is mounted on the top end of the upper shell, and a flow guide assembly for spirally guiding water is fixedly mounted on the inner edge surface of the input pipe;

[0008] The inner edge surface of the upper shell is symmetrically constructed with two annular brackets, and a separation cylinder located in the center of the upper shell is fixedly installed inside the two annular brackets. A mainstream channel is centrally opened at the top of the separation cylinder, and the inner diameter of the mainstream channel is smaller than the inner diameter of the input pipe. A sub-channel for filtering water containing impurities is formed in the upper shell through the separation cylinder and the lower shell, and an annular filter fixedly connected to the bottom end of the lower shell is installed at the bottom end of the separation cylinder.

[0009] Preferably, the flow guide assembly comprises a support tube, the support tube is located at the center of the input pipe, and a ball head is configured at the top end of the support tube.

[0010] Preferably, a plurality of spiral blades are configured in a circular array on the outer edge surface of the support tube, and one end of the plurality of spiral blades away from the support tube is fixedly connected to the inner wall of the input pipe, and one side of the spiral blades has a guide surface for causing the water to spiral forward.

[0011] Preferably, a plurality of through grooves are provided in a circular array at the top end of the annular support, and the through grooves are used for the passage of water containing impurities.

[0012] Preferably, an output pipe is installed at the bottom end of the lower shell, and flanges are fixedly installed on one end of the output pipe and the input pipe.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model filters the water entering the pipeline pump through an electric motor. During filtering, the water is guided by the guide component, causing the water to spiral forward and enter the upper shell body. Since the mass of impurities in the water body is greater than the mass of the water body, they spiral forward inside and outside the input pipe under the action of centrifugal force. After entering the upper shell body, the water without impurities in the center enters the mainstream channel, while the water containing impurities enters the sub-channel, and the water containing impurities is filtered by the annular filter, so that the impurities are stored in the sub-channel, realizing the diversion of impurities and water, thereby avoiding the problem of affecting the working efficiency of the pipeline pump due to impurities blocking the waterway, and reducing the maintenance cost of the pipeline pump.

[0015] 2. The utility model guides the water entering the input pipe through the guide assembly, causing it to spiral forward. When guiding the water, the ball head installed at one end of the support tube reduces the resistance of the water, and the water is guided by multiple spiral blades with guide curved surfaces. The guide curved surface pushes the water flowing through, realizing the spiral forward movement of the water and completing the partition of the water and impurities.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0022] Example 1: A vertical pipeline pump that prevents clogging, see Figure 1 , comprising a pipeline pump 1 and a motor 2 installed on the pipeline pump 1;

[0023] Furthermore, in order to avoid the problem of impurities blocking the waterway and affecting the working efficiency of the pipeline pump 1, and to reduce the maintenance cost of the pipeline pump 1, see Figure 1 , Figure 2 , Figure 3 , Figure 4The pipeline pump 1 has an output end 101 and an input end 102, and one end of the input end 102 is detachably mounted with a filter assembly 3 for filtering water. The filter assembly 3 includes an upper shell 301, a lower shell 302 is detachably mounted at the bottom of the upper shell 301, and an input pipe 303 is mounted at the top of the upper shell 301. A flow guide assembly 4 for spirally guiding water is fixedly mounted on the inner edge surface of the input pipe 303. The inner edge surface of the upper shell 301 is symmetrically constructed with two annular branches. The two annular brackets 304 are fixed with a separation cylinder 305 located in the center of the upper shell 301. The top of the annular bracket 304 is provided with a plurality of through grooves in an annular array, and the through grooves are used for the passage of impurity-containing water. The top of the separation cylinder 305 is provided with a main flow channel 306 in the center, and the inner diameter of the main flow channel 306 is smaller than the inner diameter of the input pipe 303. The upper shell 301 is formed with the separation cylinder 305 and the lower shell 302 to filter the impurity-containing water. The sub-flow channel 307 is provided, and the bottom end of the separation cylinder 305 is provided with an annular filter screen 308 fixedly connected to the bottom end of the lower shell 302, and the bottom end of the lower shell 302 is provided with an output pipe 309, and the output pipe 309 and one end of the input pipe 303 are fixedly provided with a flange 310, and the water entering the pipeline pump 1 is filtered by the motor 2. During the filtering, the water is guided by the guide component 4, so that the water spirals forward and enters the upper shell 301. The impurities in the water are greater than the impurities in the water due to their mass. The water quality, under the action of centrifugal force, spirals forward inside and outside the input pipe 303, and after entering the upper shell 301, the water without impurities in the center enters the main channel 306, while the water containing impurities enters the sub-channel 307, and is filtered by the annular filter 308, so that the impurities are stored in the sub-channel 307, realizing the diversion of impurities and water, thereby avoiding the problem of affecting the working efficiency of the pipeline pump 1 due to impurities blocking the waterway, and reducing the maintenance cost of the pipeline pump 1.

[0024] Furthermore, in order to realize the spiral advance of the water body and complete the partition of the water body and impurities, see Figure 1 , Figure 2 , Figure 3The diversion component 4 includes a support tube 401, which is located at the center of the input pipe 303, and a ball head 402 is configured at the top of the support tube 401. A plurality of spiral blades 403 are configured in a ring array on the outer edge surface of the support tube 401, and one end of the plurality of spiral blades 403 away from the support tube 401 is fixedly connected to the inner wall of the input pipe 303, and one side of the spiral blades 403 is provided with a diversion curved surface 404 for causing the water body to spirally move forward. The water body entering the input pipe 303 is diverted by the diversion component 4 to cause it to spirally move forward. When the water body is diverted, the ball head 402 installed at one end of the support tube 401 reduces the resistance of the water body, and the water body is diverted by a plurality of spiral blades 403 with a diversion curved surface 404.
