Description

Technical Field

[0001] This utility model relates to the technical field of grouting pile mud treatment equipment, specifically an environmentally friendly and energy-saving three-stage separation and filtration device for grouting pile mud. Background Technology

[0002] The environmentally friendly and energy-saving three-stage separation and filtration device for cast-in-place pile mud is a device for mud treatment during the construction of cast-in-place piles. Its main function is to effectively separate and filter the mud to remove solid particles in the mud, so as to achieve the purpose of environmental protection and energy saving. This device is usually used in the construction of deep foundation pits, foundation treatment and other projects. While maintaining environmental cleanliness, it also improves construction efficiency and quality.

[0003] In the three-stage separation and filtration device for grouting mud, it is necessary to use a triple filtration device to remove impurities, large particles, and small particles from the grouting mud in sequence. In the process of grouting mud treatment, the grouting mud is filtered in sequence, and the grouting mud after the initial filtration is transferred in a controlled manner to ensure the filtration efficiency of the grouting mud. However, the grouting mud treatment and transfer process is time-consuming, which leads to a decrease in the filtration efficiency of the grouting mud. Therefore, we propose an environmentally friendly and energy-saving three-stage separation and filtration device for grouting mud. Utility Model Content

[0004] To address the shortcomings of existing environmentally friendly and energy-saving three-stage separation and filtration devices for cast-in-place pile mud, this utility model provides an environmentally friendly and energy-saving three-stage separation and filtration device for cast-in-place pile mud. It features a design where the primary filter box, hydrocyclone shell, and high-efficiency filter box are sequentially integrated into a single unit. The cast-in-place pile mud can be transported and filtered sequentially, thereby improving the filtration efficiency of the cast-in-place pile mud and solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: an environmentally friendly and energy-saving three-stage separation and filtration device for grouting pile mud, comprising a frame, a hydrocyclone shell installed on one side inside the frame, a primary filter box installed on one side of the upper end of the hydrocyclone shell via a first traction pipe, a limiting pipe fixedly connected inside the hydrocyclone shell, a discharge pipe fixedly connected on one side of the upper part of the limiting pipe, a first spiral blade installed inside the limiting pipe to drive large particles of impurities upward, a second spiral blade fitted inside the hydrocyclone shell, a second filter screen fixedly connected to the bottom end of the hydrocyclone shell, a rotating base fixedly connected to the lower end of the second spiral blade, a conical tube installed at the lower end of the second filter screen, a high-efficiency filter box connected to the lower end of the conical tube via a second traction pipe, a circular filter cylinder movably fitted inside the high-efficiency filter box, and a motor installed on the outside of one end of the high-efficiency filter box.

[0006] Preferably, a first filter screen for preliminary filtration of the product is installed on the upper part of the primary filter box. A scraper is movably sleeved on the outside of the first filter screen. The first filter screen is installed obliquely on the upper part of the primary filter box, and the scraper is attached to the outside of the first filter screen.

[0011] Preferably, the circular filter cartridge has filter holes on its outside, and the high-efficiency filter box is installed at an angle to the horizontal plane. The gear installed at one end of the motor output shaft meshes with the outside of the circular filter cartridge.

[0012] Compared with existing environmentally friendly and energy-saving three-stage separation and filtration devices for cast-in-place pile mud, this utility model has the following advantages:

[0013] 1. This environmentally friendly and energy-saving three-stage separation and filtration device for grouting pile mud involves three-stage filtration of the pile mud through a primary filter box, a hydrocyclone shell, and a circular filter cartridge. This ensures the removal of impurities, large mud lumps, and tiny particles from the pile mud, ensuring fine filtration and improving its filtration efficiency. Furthermore, the three-stage filtration device operates in a linked manner, enhancing the overall filtration efficiency of the equipment.

[0014] 2. This environmentally friendly and energy-saving three-stage separation and filtration device for cast-in-place pile mud uses a first filter screen installed at an angle to effectively filter impurities. When the outside of the first filter screen becomes clogged, a scraper filters the clogged impurities. At the same time, the second spiral blades are attached to the upper part of the second filter screen. When the second spiral blades rotate, they can scrape off the clogged impurities on the upper part of the second filter screen. The circular filter cylinder also rotates during filtration. In other words, the problem of filter hole clogging can be avoided in all three stages of filtration, thus improving filtration efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5An environmentally friendly and energy-saving three-stage separation and filtration device for cast-in-place pile mud includes a frame 1. A hydrocyclone shell 2 is installed on one side inside the frame 1. The hydrocyclone shell 2 further filters the pile mud, removing large particles of impurities. A primary filter box 4 is installed on one side of the upper end of the hydrocyclone shell 2 via a first traction pipe 3. The primary filter box 4 filters impurities inside the pile mud. A limit pipe 7 is fixedly connected inside the hydrocyclone shell 2. A discharge pipe 8 is fixedly connected to one side of the upper part of the limit pipe 7. A first spiral blade 9 is installed inside the limit pipe 7 to drive large particles of impurities upward. When the first spiral blade 9 rotates, it moves against the outside of the hydrocyclone. Large particles of impurities generated by the internal layering of the shell 2 are removed. A second spiral blade 10 is fitted inside the shell 2 of the hydrocyclone. A second filter screen 11 is fixedly connected to the bottom end of the shell 2 of the hydrocyclone. A rotating base 12 is fixedly connected to the lower end of the second spiral blade 10. A conical tube 13 is installed at the lower end of the second filter screen 11. The lower end of the conical tube 13 is connected to a high-efficiency filter box 15 through a second traction tube 14. A circular filter cylinder 17 is movably fitted inside the high-efficiency filter box 15. The circular filter cylinder 17 rotates to perform three-stage filtration of the pile mud, ensuring that the tiny particles inside the pile mud are finely filtered and improving its filtration efficiency. A motor 18 is installed on the outside of one end of the high-efficiency filter box 15.

[0023] Please see Figure 4 The upper part of the primary filter box 4 is equipped with a first filter screen 5 for preliminary filtration of the product. A scraper 6 is movably sleeved on the outside of the first filter screen 5. The first filter screen 5 is installed obliquely on the upper part of the primary filter box 4, and the scraper 6 is attached to the outside of the first filter screen 5. By installing the first filter screen 5 on the outside of the primary filter box 4, the pile injection mud is put into the inside of the primary filter box 4. The pile injection mud comes into contact with the first filter screen 5, and the first filter screen 5 performs preliminary filtration of impurities inside the pile injection mud to prevent impurities from affecting the quality of the pile injection mud. At the same time, the scraper 6 is sleeved on the outside of the first filter screen 5. When impurities clog the outside of the first filter screen 5, the scraper 6 slides and scrapes away the impurities that clog the outside of the first filter screen 5 to prevent the first filter screen 5 from clogging and affecting the filtration efficiency.

[0024] Please see Figure 3 The limiting pipe 7 is installed in the middle of the second spiral blade 10, and a waste collection bucket is installed on the outside of the discharge pipe 8. The discharge pipe 8 installed at the upper end of the limiting pipe 7 extends to the outside of the frame 1. At the same time, the large particle impurities separated by the limiting pipe 7 are transported upwards and discharged through the discharge pipe 8.

[0025] Please see Figure 3 and Figure 5A set of motors is installed on the upper part of the first spiral blade 9 and the lower end of the rotating base 12. The second spiral blade 10 is conical. The motor drives the second spiral blade 10 to rotate. The second spiral blade 10 is spiral-shaped. After the pile mud is put into the inside of the hydrocyclone shell 2, the rotation of the second spiral blade 10 drives the pile mud to separate. Large particles of impurities float and small particles of impurities settle. At the same time, the first spiral blade 9 is set in the middle of the hydrocyclone shell 2. When the first spiral blade 9 rotates, it drives the large particles of impurities floating at the top to be discharged, thereby ensuring the efficiency of impurity filtration.

[0026] Please see Figure 5 The second filter screen 11 has filter holes on its outside and the filter holes are located on the outside of the rotating base 12. The rotating base 12 is located in the middle of the second filter screen 11 and the second filter screen 11 has filter holes on its outside. After small particulate impurities are filtered in layers inside the hydrocyclone shell 2, the small particulate impurities are discharged downward through the filter holes opened inside the second filter screen 11, ensuring the filtration efficiency of the pile mud.

[0027] Please see Figure 2 The high-efficiency filter box 15 is located at the lower end inside the frame 1. The lower end of the high-efficiency filter box 15 is equipped with a discharge pipe 16 that drives the discharge of small particulate impurities. The discharge pipe 16 is fixedly connected to the lower end of the high-efficiency filter box 15. The filter device inside the high-efficiency filter box 15 performs a third filtration on the pile mud, filters out small particulate impurities inside the pile mud, and the impurities are discharged through the discharge pipe 16.

[0028] Please see Figure 2 The circular filter cylinder 17 has filter holes on its outside, and the high-efficiency filter box 15 is installed at an inclination to the horizontal plane. The gear installed at one end of the output shaft of the motor 18 meshes with the outside of the circular filter cylinder 17. When the motor 18 is started, the motor 18 drives the circular filter cylinder 17 to rotate. The circular filter cylinder 17 drives the pile mud to rotate and filter. The small particulate impurities inside the pile mud are finely filtered and discharged through the circular filter cylinder 17. At the same time, the small particulate impurities are output downward through the discharge pipe 16.

[0029] Working principle: During use, the grouting mud is put into the first-stage filter box 4. The first filter screen 5 filters the grouting mud and removes impurities from its interior. At the same time, the grouting mud is transported to the hydrocyclone shell 2 via the first traction pipe 3. When the second spiral blade 10 rotates, it moves the grouting mud. The grouting mud undergoes stratification inside the hydrocyclone shell 2. Small particles of impurities settle to the bottom, while large particles float. When the first spiral blade 9 rotates, it removes large particles of impurities. At the same time, the grouting mud is transported to the conical tube 13 via the second spiral blade 10, and then transported to the circular filter cylinder 17 via the second traction pipe 14. The circular filter cylinder 17 performs fine filtration on the grouting mud again, ensuring that the mud is clean and tidy.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
