Description

Technical Field

[0001] The utility model patent relates to the technical field of machine pumps, specifically a sealed water circulation machine pump device for producing urea. Background Art

[0002] In the process of producing urea, a sealed water circulating pump is needed to supply water to the production equipment. The sealed water circulating pump has high working efficiency and has the advantages of simple and compact structure, light weight, strong self-priming ability and insensitivity to oil contamination.

[0003] Although the existing sealed water circulation pump has advantages such as high working efficiency, it is inevitable that there are still some shortcomings in its actual use. For example, the device lacks an impurity separation mechanism, so that rust and scale residues in the water can enter the inside of the pump, causing damage to the pump. In order to avoid such problems, a filter is usually added at the water inlet end to filter the water entering the pump through the filter element inside the filter. However, the filtering effect of the filter element inside the filter will decrease with the increase of use time, and the internal filter element needs to be replaced frequently, which not only leads to an increase in use cost, but also frequent shutdowns to replace the filter element will affect the operating efficiency. Based on this, the present application proposes a sealed water circulation pump device for producing urea to solve the existing problems. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0021] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Figures 1 to 3 , and describes the application in detail with reference to embodiments. Example 1

[0022] Example 1 discloses a sealed water circulation pump device for producing urea, including a pump 1, a water inlet pipe 2 and a filter tube 3, wherein the water inlet pipe 2 is connected to the inlet end of the pump 1, and the filter tube 3 is fixed to the bottom end of the water inlet pipe 2 through a flange.

[0023] In order to intercept and collect impurities in the water, a collection box 4 is connected to the bottom of the filter tube 3, and a plurality of filter holes 5 connected to the water inlet pipe 2 are opened at the top of the inner cavity of the filter tube 3. A rotating rod 6 is rotatably connected to the closed end surface of the filter tube 3 through a sealed bearing, and one end of the rotating rod 6 extends to the inside of the filter tube 3. A plurality of cleaning plates 8 are fixedly arranged on the rotating rod 6 located inside the filter tube 3. The cleaning plates 8 can act on the inner wall of the filter tube 3 and scrape off the impurities at the filter holes 5 under the drive of the rotating rod 6. At the same time, a plurality of blades 7 are fixedly arranged on the rotating rod 6 near the water inlet end of the filter tube 3. When the water flows into the inside of the filter tube 3, the blades 7 can be acted on to make the rotating rod 6 rotate.

[0024] In addition, in order to facilitate the discharge of impurities and know the liquid level of impurities in the collection box 4, a drain pipe 18 is connected to one side of the collection box 4, a valve 19 is provided on the surface of the drain pipe 18, and a sight glass 20 is also provided on the front side of the collection box 4. Example 2

[0025] Example 2 discloses a sealed water circulation machine pump device for producing urea that is further improved on the basis of Example 1. The similarities with Example 1 are not described again. The difference is that an emergency mechanism 9 is also provided between the rotating rod 6 and the filter tube 3 in this Example 2.

[0026] The specific emergency mechanism 9 includes a drive motor 10, which is slidably arranged on the outer side of the closed end surface of the filter tube 3. The output shaft of the drive motor 10 is fixedly connected to the rotating shaft 11 through a coupling, and the latch rod 12 is fixedly connected through the rotating shaft 11. At the same time, a socket 13 used in conjunction with the latch rod 12 is fixedly connected to the outer end of the rotating rod 6, so that a clutch connection component can be formed between the latch rod 12 and the socket 13. Of course, the clutch connection component can also be a first toothed wheel and a second toothed wheel respectively connected to the rotating shaft 11 and the outer end of the rotating rod 6, and the tooth surfaces on the first toothed wheel and the second toothed wheel are designed relatively, and when the two are fitted together, they can also effectively play a transmission role.

[0027] In addition, a threaded rod 14 is rotatably connected to the closed end surface of the filter tube 3 through a bearing, a threaded sleeve 15 is threadedly connected to the surface of the threaded rod 14, and the top of the threaded sleeve 15 is fixedly connected to the bottom of the drive motor 10. At the same time, a limit slide bar 16 is fixedly connected to the closed end surface of the filter tube 3, and the two limit slide bars 16 are respectively located at the front and rear sides of the drive motor 10. A sliding sleeve 17 is slidably arranged on the surface of each limit slide bar 16, and the two sliding sleeves 17 are fixedly connected to the front and rear sides of the drive motor 10. The above-mentioned threaded rod 14 and the limit slide bar 16 can play a role in moving and guiding the drive motor 10.

[0028] When the sealed water circulation pump device for producing urea disclosed in the present embodiment 2 is used, the circulating water delivery pipeline is connected to the inlet end of the filter tube 3, and water is supplied to the inside of the filter tube 3. After the water is supplied to the inside of the filter tube 3, the water source carries rust residues and scale residues and flows to the water inlet pipe 2. In the process of the water source flowing to the water inlet pipe 2, a large amount of rust residues and scale residues fall into the collecting box 4 due to their own weight and are collected, and a small amount is filtered to the filter hole 5 along the water potential and is filtered and intercepted by the filter hole 5;

[0029] When the water source flows, the water force will also drive the blades 7 to rotate, prompting the blades 7 to drive the rotating rod 6 to rotate continuously, and the rotation of the rotating rod 6 drives a number of cleaning plates 8 to continuously clean the impurities in the filter holes 5;

[0030] When the water flow is at a low flow rate and the blades 7 cannot be effectively driven to rotate, the operator first calibrates the latch rod 12 and the socket 13, and then adjusts the position of the positioning drive motor 10 and the latch rod 12 until the latch rod 12 and the socket 13 are assembled and connected, and finally starts the drive motor 10, using the drive motor 10 as the driving source to drive the rotating rod 6 to rotate, thereby stably and continuously cleaning the filter holes 5 through the cleaning plate 8.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
