[0003] In the daily use of circulating pump, various impurities can be carried in the feed liquid. These impurities are easy to cause the blockage of the driving part after entering the driving part of the circulating pump with the feed liquid. Once the driving part is blocked, the operating efficiency of the circulating pump will be greatly reduced, but the above-mentioned circulating pump lacks a component for removing and filtering the impurities in the feed liquid, so it is difficult to pre-intercept the impurities in the feed liquid, and therefore a anti-blocking circulating pump capable of pre-intercepting the impurities in the feed liquid is particularly important. UTILITY MODEL CONTENTS

[0004] In view of the above prior art, the technical problem to be solved by the utility model is that the circulating pump lacks a filtering component, which is easy to cause the blockage of the driving part on the pump body.

[0011] As a further improvement of the application, a first sliding groove is arranged in the filter pipe, and a first sliding plate is slidably connected in the first sliding groove and fixedly connected with the filter plate.

[0012] As a further improvement of the application, a spring is fixedly connected to the first sliding plate, and an end of the spring away from the first sliding plate is fixedly connected to the inner wall of the first sliding groove.

DETAILED DESCRIPTION

[0025] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0026] First embodiment:

[0027] Figures 1-3 A circulating pump with an anti-blocking structure is shown, comprising a pump body 101 fixedly connected to a base 1, further comprising:

[0028] A drive part 2 is fixedly connected to the base 1, and the drive part 2 is connected to the drive end of the pump body 101;

[0029] The drive part 2 is fixedly connected with an infusion pipe 202 and a liquid outlet pipe 201;

[0030] A filter pipe 3 is fixedly connected to the infusion pipe 202;

[0031] A filter plate 5 is slidingly connected in the filter pipe 3.

[0032] A first sliding groove 302 is provided in the filter pipe 3, and a first sliding plate 501 is slidingly connected in the first sliding groove 302, and the first sliding plate 501 is fixedly connected to the filter plate 5.

[0033] A spring 3021 is fixedly connected to the first sliding plate 501, and the end of the spring 3021 away from the first sliding plate 501 is fixedly connected to the inner wall of the first sliding groove 302.

[0034] The spring 3021 provided in the first sliding groove 302 can further enable the first sliding plate 501 to quickly reset.

[0035] Figure 4 A second sliding groove 303 is provided in the filter pipe 3, and a second sliding plate 502 is slidingly connected in the second sliding groove 303, and the second sliding plate 502 is fixedly connected to the filter plate 5.

[0036] The second sliding plate 502 further limits the filter plate 5 in the second sliding groove 303, thereby further ensuring the stability of the filter plate 5 when sliding.

[0037] Figure 4 A magnetic block 3031 is fixedly connected in the second sliding groove 303, and the second sliding plate 502 is a magnetic plate, and the second sliding plate 502 is attracted to the magnetic block 3031.

[0038] Figure 5 It is shown that the filter plate 5 is fixedly connected with the pushing plate 6.

[0039] The pushing plate 6 is an arc-shaped plate, and guide slopes 601 are arranged on both sides of the pushing plate 6.

[0040] By arranging the pushing plate 6 as an arc-shaped plate and arranging the guide slopes 601 on the pushing plate 6, the possibility of impurities falling on the pushing plate 6 can be reduced, so that the material can be fully pushed out.

[0041] It should be further pointed out that the guide slopes 601 are inclined slopes, and the inclined ends are directed to the liquid inlet end of the filter pipe 3.

[0042] In use, the liquid inlet pipe 301 with the flange plate 7 is fixedly connected to the filter pipe 3, at this time the pump body 101 is started, the liquid will be sucked into through the liquid inlet pipe 301, and then through the filter pipe 3 and the liquid conveying pipe 202, and finally discharged through the liquid outlet pipe 201;

[0043] When the filter pipe 3 filters the liquid, the liquid is input into the filter pipe 3 through the liquid inlet pipe 301, which pushes the filter plate 5 to move, and after the filter plate 5 moves a distance, the two symmetrical first sliding plates 501 slide to the maximum range in the first sliding groove 302, at this time the filter plate 5 is limited by the liquid, and the liquid is fully filtered when passing through the filter plate 5, and the filtered liquid passes through the driving part 2 and is discharged through the liquid outlet pipe 201;

[0044] The present application can effectively filter most of the impurities in the liquid by adding the filter pipe 3 at the front end of the liquid conveying pipe 202, thereby reducing the influence of impurities on the driving part 2 and reducing the possibility of the driving part 2 being blocked, and improving the liquid conveying efficiency.

[0045] When the feeding is finished, the pump body 101 is closed at this time, the liquid inlet pipe 301 stops inputting liquid into the filter pipe 3 at this time, the pushing force of the liquid on the filter plate 5 disappears, the filter plate 5 will be quickly reset under the action of the spring 3021, the filter plate 5 will drive the second sliding plate 502 to slide and reset synchronously, when the second sliding plate 502 slides a distance, the second sliding plate 502 will be magnetically attracted by the magnetic block 3031, at this time the second sliding plate 502 quickly slides close to the magnetic block 3031, and after sliding a distance, it is attracted to the magnetic block 3031, when the second sliding plate 502 is attracted to the magnetic block 3031, the filter plate 5 itself will vibrate due to impact, at this time the impurities remaining on the filter plate 5 will be shaken off, at this time the worker can remove the liquid inlet pipe 301 to clean the impurities filtered in the filter pipe 3.

[0046] During the sliding process of the filter plate 5, the pushing plate 6 on the filter plate 5 will move synchronously, the pushing plate 6 will push the impurities filtered in the filter pipe 3 and push the impurities to the end close to the liquid inlet pipe 301.

[0047] It should be noted that the spring 3021 is a hard spring, and the reset elastic force can stably push the filter plate 5 and the impurities to move.

[0048] It should be further noted that the liquid inlet pipe 301 is connected to the external liquid storage tank away from the one end of the filter pipe 3.

[0049] The second embodiment:

[0050] A circulating pump with an anti-blocking structure is basically the same as the first embodiment, and further, a discharge groove is formed on the filter pipe 3, and a sealing plate 4 is detachably connected in the discharge groove, and a handle 401 is fixedly connected on the sealing plate 4.

[0051] When the discharge is needed, the staff can not disassemble the liquid inlet pipe 301, and by manually pulling the sealing plate 4, the filtered impurities in the filter pipe 3 can be discharged, and the discharge efficiency is further improved.

[0052] It should be noted that in order to ensure that the sealing plate 4 will not be washed off during the infusion process, the sealing plate 4 can be a strong magnetic plate that can be purchased on the market, and when the sealing plate 4 is clamped into the clamping groove on the filter pipe 3, the sealing plate 4 is attracted to the filter pipe 3 to ensure the stability of the sealing plate 4 after installation.

[0053] In combination with the current actual demand, the above-mentioned embodiments adopted by the present application do not limit the protection scope, and various changes made within the knowledge range of those skilled in the art without departing from the concept of the present application still fall within the protection range of the present application.
