Description
Technical Field
[0001] This utility model relates to the field of slurry pump technology, specifically a cooling device for a slurry pump used in cement mixing pile construction. Background Technology
[0002] Cement mixing piles are an effective form of soft soil treatment. They use cement as the main curing agent, and a mixing pile machine is used to spray cement into the soil and mix it thoroughly. This causes a series of physical and chemical reactions between the cement and the soil, which hardens the soft soil and improves the foundation strength.
[0003] Cement mixing piles are classified into single-axis and double-axis mixing piles according to the main construction methods used. The cement slurry is mixed by a fully automatic mixer according to the specified mix ratio and flows into the mixing tank. The slurry in the mixing tank is pumped to the drill bit of the mixing pile machine by a slurry pump. A series of physical and chemical reactions occur between the slurry and the soil and the soft soil, which consolidates the soil and forms a cement-soil pile with integrity, water stability and certain strength.
[0004] In actual engineering construction, the workload of soft soil foundation treatment is often very large. During the suction and discharge process of the grout pump, the acceleration and deceleration of the liquid will generate a certain amount of heat. Especially when there is pressure loss or friction loss in the pipeline system, if this heat cannot be effectively dissipated, it will lead to faster wear and damage of the grout pump, thereby shortening the service life of the equipment. This situation not only increases maintenance costs, but may also cause delays in the project schedule due to equipment failure, affecting the timely completion of the project. Therefore, a grout pump cooling device for cement mixing pile construction is proposed to address the above problems. Utility Model Content

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.

[0026] Please see Figure 1-4 This utility model provides a technical solution:
[0027] A grout pump cooling device for cement mixing pile construction includes a grout pump body 1 and a pumping pipe 2. The pumping pipe 2 is fixedly connected to the upper end of the grout pump body 1, a water storage component 3 is fixedly connected to the top of the grout pump body 1, a water spray cooling component 4 is fixedly connected to the upper end of the grout pump body 1, an intravenous infusion set 5 is fixedly connected to one side of the water storage component 3, the water storage component 3 includes a water tank 31, a water trough 32 is formed inside the water tank 31, a silicone stopper 33 is installed inside the water tank 31, and the water trough 32 is formed inside the water tank 31. A spring 34 is fixedly connected to the upper end, a push plate 35 is fixedly connected to the bottom end of the spring 34, a sealing ring 36 is fixedly connected to the outside of the push plate 35, a guide rod 37 is fixedly connected to the top of the push plate 35, a handle 38 is fixedly connected to the top of the guide rod 37, a constant pressure hole 39 is opened at the upper end of the water tank 31, the water spray cooling assembly 4 includes a door shell 41, a water inlet hole 42 is opened on the inner side of the upper end of the door shell 41, a water flow channel 43 is opened on the inner side of the door shell 41, and a mist nozzle 44 is fixedly connected to one side of the door shell 41.
[0028] As a further implementation of this solution, a bracket is fixedly connected to the bottom of the water bucket 31. The bottom of the water bucket 31 is fixedly connected to the top of the pump body 1 through the bracket. A water inlet is provided on the inner side of the water bucket 31 near the silicone plug 33. A gap is provided between the top of the silicone plug 33 and the top of the water trough 32 in the water bucket 31. The gap between the top of the silicone plug 33 and the water trough 32 is the same as the thickness of the push plate 35. The water inlet facilitates the rapid replenishment of water. The gap design between the silicone plug 33 and the water trough 32 ensures that water will not overflow during the water filling process. At the same time, after the push plate 35 is at the top of the water bucket 31, the push plate 35 is at the top of the silicone plug 33, which allows water to be added to the inside of the water bucket 31.
[0029] As a further implementation of this solution, a through hole is provided on the inner side of the water bucket 31 near the intravenous infusion set 5. The water bucket 31 is connected to the inside of the intravenous infusion set 5 through the through hole. One end of the intravenous infusion set 5 is fixedly connected to the top of the water inlet hole 42 opened in the door shell 41. The intravenous infusion set 5 is connected to the inside of the flow channel 43 opened in the door shell 41 through the water inlet hole 42, so that the water inside the water bucket 31 can enter the inside of the door shell 41 through the intravenous infusion set 5. The flow rate of the water entering the inside of the door shell 41 can be controlled by the intravenous infusion set 5.
[0030] As a further implementation of this solution, the water tank 31 is a hollow cylinder, the water trough 32 is cylindrical at both ends, and the water trough 32 extends through the upper end of the water tank 31. The guide rod 37 and the push plate 35 are both cylindrical, sliding inside the water trough 32. The guide rod 37 slides inside the upper end of the water trough 32. The cylindrical shapes of the guide rod 37 and the push plate 35, along with their sliding mechanism inside the water trough 32, provide a stable movement path and good sealing. This design helps to precisely control the flow of coolant, ensuring the efficient operation of the cooling system.
[0031] As a further implementation of this solution, the constant pressure hole 39 penetrates the upper end of the water tank 31 and is connected to the water trough 32. The outer side of the sealing ring 36 fits against the inner side of the water trough 32 opened in the water tank 31. A rubber plug is installed inside the constant pressure hole 39. The fit between the sealing ring 36 and the inner side of the water trough 32 forms a closed water flow channel, ensuring that the coolant will not leak. The setting of the constant pressure hole 39 can control the air pressure inside the water tank 31, which helps to control the flow of water.
[0032] As a further implementation of this solution, the door shell 41 is fitted onto the outside of the pumping pipe 2. The inner side of the door shell 41 near the mist nozzle 44 has a through hole, and the water inlet 42 is connected to the flow channel 43. The flow channel 43 is connected to the mist nozzle 44 through the through hole of the door shell 41. This design allows the coolant to be evenly distributed in the working area of the pump, improving the cooling efficiency and reducing the risk of the pump being damaged due to overheating.
[0033] Workflow: To cool the heat generated by the liquid flow in the device's pipeline, the flow rate of the liquid flowing through the intravenous infusion set 5 is first adjusted by the flow regulator on the set. The rubber stopper inside the constant pressure orifice 39 is removed. At this point, under the force of the spring 34, the push plate 35 is pushed downwards. The push plate 35 drives the guide rod 37 and handle 38 downwards simultaneously. The push plate 35 and guide rod 37 slide inside the water tank 32. The guide rod 37 improves the stability of the push plate 35 during downward movement. The diameter of the handle 38 is larger than the diameter of the guide rod 37 to prevent the guide rod 37 from completely entering the water tank 31. The sealing ring 36 seals the push plate 35 and the water tank 31. As the push plate 35 moves downwards, external air enters the water tank 31 through the constant pressure orifice 39. By controlling the flow through the constant pressure orifice 39, the water flow is controlled. Under the squeezing action of the push plate 35, water inside the water tank 32 flows out... The intravenous infusion set 5 enters the water inlet 42 of the door shell 41, then enters the flow channel 43, and finally enters the mist nozzle 44. Under the action of the spring 34, the pressure and continuity of the water flow are ensured. The water is sprayed in a mist form through the mist nozzle 44 onto the pumping pipe 2 of the slurry pump body 1, which increases the contact area between the water and the pumping pipe 2, thereby reducing the temperature of the pumping pipe 2 and achieving the dual effects of cooling and lubrication. When adding water to the water tank 31, the handle 38 is pulled to move the guide rod 37 and the push plate 35 upward. When the bottom of the push plate 35 is at the top of the silicone plug 33, the silicone plug 33 is removed, thus adding water to the water tank 31. The device solves the problem of rapid wear and short life of the slurry pump during cement mixing pile construction. It not only improves the service life of the slurry pump, but also greatly reduces the construction cost of re-driving the mixing pile due to slurry pump damage, and ensures the construction quality.
[0034] 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.
