Description

Technical fields:

[0001] This utility model belongs to the field of flocculant preparation and production, and particularly relates to a flocculant preparation device for desliming geotextile filter bags. Background technology:

[0002] Geofilter bag dewatering technology refers to the process of dewatering sludge using geofilter bags. Geofilter bags are tubular geotextile bags with a filtration structure woven from special polymer materials, possessing high strength and long-term UV resistance. Their working principle involves adding sludge dewatering agents (flocculators) to promote the separation of mud and water. Water seeps out of the bag, while sludge remains inside. The combined effect of the soil's own weight and external pressure causes the water inside the bag to drain rapidly, reducing the voids between soil particles and accelerating soil consolidation.

[0003] The agents added in geotextile filter bag desludge removal processes are typically flocculants. Taking the preparation of cationic PMA flocculants, which have good flocculation effects, as an example, the flocculant needs to be mixed with water to form a solution before it can be added to the sludge. Current technologies usually use large mixing tanks to mix the flocculant and water. Although large mixing tanks produce a large output of solution, they have high procurement costs, high energy consumption, and complex maintenance. Furthermore, the agitator in the mixing tank is located at the tank's axis, making it difficult to uniformly agitate the flocculant that settles to the bottom of the tank. This results in significant fluctuations in the flocculant concentration within the tank, leading to a decline in the subsequent sludge treatment effect. Summary of the Invention:

[0004] The purpose of this invention is to provide a flocculant preparation device for desliming geotextile filter bags, and to overcome the shortcomings of the prior art, effectively solving the existing problem of uneven preparation of cationic PMA flocculants.

[0005] The present invention relates to a flocculant preparation device for desliming geotextile filter bags, comprising a first dissolving tank and a second dissolving tank. A circulation pump is installed on the bottom side wall of both the first and second dissolving tanks. The output pipes of the two circulation pumps are respectively connected to the top openings of the first and second dissolving tanks. A drain pipe is connected to both output pipes, and both drain pipes are connected to a main drain pipe.

[0006] Furthermore, both output pipes are connected to a water supply pipe, and both water supply pipes are connected to the main water supply pipe.

[0007] Furthermore, dosing pipes are connected to the top inclined surfaces of both the first and second dissolving tanks.

[0008] Furthermore, ladders are installed on the side walls of both the first and second dissolving tanks.

[0009] Furthermore, level sensor alarms are installed on both the first and second dissolving tanks.

[0010] The beneficial effects of this utility model are: simple structure, easy operation, and low cost. The circulating pump can drive the preparation solution in the first and second dissolving tanks to circulate. By utilizing the shear force and hydraulic disturbance of the flow, the contact area between the flocculant particles and water can be accelerated, the dispersion efficiency can be improved, and thus the flocculant and water can be uniformly mixed in the flow.

[0012] In the diagram, 1 is the first dissolving tank, 2 is the second dissolving tank, 3 is the circulating pump, 4 is the output pipeline, 5 is the drain pipe, 6 is the main drain pipe, 7 is the water supply pipe, 8 is the water supply pipe, 9 is the chemical dosing pipe, 10 is the feeding ladder, 11 is the liquid level sensor alarm, 12 is the first valve, 13 is the second valve, and 14 is the third valve. Detailed implementation method:

[0013] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings:

[0014] like Figure 1 As shown, a flocculant preparation device for desliming geotextile filter bags includes a first dissolving tank 1 and a second dissolving tank 2. A circulation pump 3 is installed on the bottom sidewall of both the first dissolving tank 1 and the second dissolving tank 2. The output pipes 4 of the two circulation pumps 3 are respectively connected to the top openings of the first dissolving tank 1 and the second dissolving tank 2. A drain pipe 5 is connected to each of the two output pipes 4, and both drain pipes 5 are connected to a main drain pipe 6. A water supply pipe 7 is connected to each of the two output pipes 4, and both water supply pipes 7 are connected to a main water supply pipe 8. A dosing pipe 9 is connected to the top inclined surface of both the first dissolving tank 1 and the second dissolving tank 2. A feeding ladder 10 is installed on the sidewall of both the first dissolving tank 1 and the second dissolving tank 2. A liquid level sensor alarm 11 is installed on both the first dissolving tank 1 and the second dissolving tank 2.

[0015] Specifically, the circulating pump 3 can drive the preparation solution in the first dissolving tank 1 and the second dissolving tank 2 to circulate, thereby promoting the uniform mixing of flocculant and water in the flow.

[0016] In actual use, workers use the feeding ladder 10 to add flocculant through the lower dosing pipe 9 into the first dissolving tank 1 and the second dissolving tank 2. At this time, the corresponding two circulation pumps 3 are started, the first valve 12 is opened, and the second valve 13 and the third valve 14 are closed. This allows the prepared solution in the first dissolving tank 1 and the second dissolving tank 2 to enter the circulation pump 3 from the bottom, thus preventing the flocculant from settling at the bottom of the tank for a long time. The solution is then returned to the first dissolving tank 1 and the second dissolving tank 2 through the corresponding two output pipes 4. During this circulation process, the continuous shear force and hydraulic disturbance can accelerate the contact area between the flocculant particles and water, improve the dispersion efficiency, and effectively break the entanglement of molecular chains, promote the expansion of molecular chains and the release of active sites. Through forced convection, areas with excessively high or low flocculant concentrations in the first dissolving tank 1 and the second dissolving tank 2 can be quickly eliminated, preventing undissolved particles from entering the tank. Deposition allows for more uniform mixing of flocculant and water. When the prepared solution is ready, the first valve 12 is closed and the second valve 13 is opened. At this time, the two circulating pumps 3 transport the prepared solution from the first dissolving tank 1 and the second dissolving tank 2 to the drain pipe 5, and then through the main drain pipe 6, the prepared solution is centrally transported to the geotextile filter bag desludge tank for use. If water needs to be replenished during the circulation of the prepared solution in the first dissolving tank 1 and the second dissolving tank 2, the third valve 14 can be opened, and external water source can be pressurized and introduced into the water replenishment main pipe 8. At this time, the water replenishment pipe 7 injects the replenished water source into the output pipe 4, and finally flows into the first dissolving tank 1 and the second dissolving tank 2, thus achieving the effect of replenishing water while continuously circulating the prepared solution without stopping the machine. Depending on the required amount of prepared solution, both dissolving tanks can be used simultaneously, or one of them can be shut down as a backup device, which reduces energy consumption while ensuring continuous output of the prepared solution.

[0017] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
