Description
Technical Field
[0001] The utility model belongs to the technical field of sand filter tanks, and in particular relates to a sand filter tank with a heat insulation structure. Background Art
[0002] Sand filter tank is a commonly used water treatment equipment, usually used to remove suspended matter, impurities and microorganisms in water. Its principle is to filter through multiple layers of sand layers, intercept impurities and pollutants in the water in the sand filter tank, so as to achieve the purpose of purifying water quality. When water enters the sand filter tank from the top, through the action of gravity and the filtering effect of the sand layer, the impurities and pollutants in the water are gradually intercepted in the sand layer, and the clean water is discharged through the outlet at the bottom. Sand filter tank is suitable for urban water supply systems, industrial water, sewage treatment and other fields. It is an economical and effective water treatment equipment.
[0003] Most of the sand filter tanks on the market still have the following problems when in use:
[0004] 1. When the traditional sand filter tank is used in a low temperature or cold environment, the residual water inside may freeze, causing the water outlet to be blocked by ice, making it impossible to perform filtering operations, and the antifreeze effect is poor;
[0005] 2. Most sand filter tanks need to be filled with water to be filtered into the water inlet during use. This requires the water inlet to be kept open at all times. Dust or particles may enter the open water inlet, affecting the cleanliness of the sand and gravel inside the sand filter tank, causing the internal sand and gravel to need to be replaced more frequently, and the dust prevention effect is poor.

[0028] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a sand filter tank with a heat insulation structure of the utility model in conjunction with the accompanying drawings.
[0029] like Figure 1-5 As shown, a sand filter tank with a heat insulation structure of the utility model comprises a sand filter tank body 1, an external frame 15 is fixedly connected to the bottom of the sand filter tank body 1, a heating device 16 is fixedly connected inside the external frame 15, a heating pipe 17 is fixedly connected inside the external frame 15, a heat-conducting copper pipe 18 is fixedly connected to the side of the external frame 15, a fixing plate 19 is fixedly connected to the front and back of the external frame 15, and a fixing bolt 20 is connected inside the fixing plate 19 by threading. The external frame 15 is fixedly connected to the bottom of the sand filter tank body 1, and the heating device 16 is fixedly connected inside the external frame 15. By turning on the heating device 16, the heating pipe 17 and the heating device 16 can emit heat, and the heat is transported to the inside of the sand filter tank body through the heat-conducting copper pipe 18, so that when the sand filter tank is used in a relatively cold environment, the inside is not easy to freeze, and the antifreeze effect is better.
[0030] The top of the sand filter tank body 1 is connected to a fixing ring 9 by bolts, and a dust cover 10 is fixedly connected to the top of the fixing ring 9. The surface of the dust cover 10 is fixedly connected to a fixing block 11, and the side of the fixing block 11 is connected to a rotating shaft frame 12 by a rotating shaft. The side of the rotating shaft frame 12 is fixedly connected to a cover plate 13, and the top of the cover plate 13 is fixedly connected to a handle 14. The fixing ring 9 is connected to the top of the sand filter tank by bolts, and a dust cover is fixedly connected to the top of the fixing ring 9. In this way, when the sand filter tank is undergoing a filtering process, the dust cover top can be covered by the cover plate 13 to prevent particulate matter and dust in the air from floating into the sand filter tank, which causes the sand and gravel inside the sand filter tank to need to be frequently replaced, and the dust prevention effect is better.
[0031] An insulation board 2 is provided on the surface of the sand filter tank body 1, and holes 8 are opened on the surface of the insulation board 2. The insulation board 2 provided on the surface of the sand filter tank body 1 can prevent heat from entering the interior of the sand filter tank, so that the interior of the sand filter tank always maintains a relatively normal temperature, and it is not easy to cause accidents due to temperature imbalance, and the insulation effect is better.
[0032] The top of the sand filter tank body 1 is fixedly connected with a water inlet 3, and the bottom plate of the sand filter tank body 1 is fixedly connected with a water outlet 6. The water to be filtered can be input into the sand filter tank through the water inlet 3. After passing through the sand and gravel structure and the water filtration system inside the sand filter tank, the filtered water is discharged at the water outlet 6, and the filtering effect is better.
[0033] A feed port 4 is fixedly connected to the surface of the sand filter tank body 1, and a maintenance port 5 is fixedly connected to the surface of the sand filter tank body 1. Sand and gravel can be filled through the feed port 4 on the surface of the sand filter tank. When the sand and gravel inside the sand filter tank need to be supplemented or replaced, the feed port 4 can be opened to pour the sand and gravel into the sand filter tank, and the filling is more convenient.
[0034] The bottom of the sand filter tank body 1 is fixedly connected with a foot support 7, and the foot support 7 is evenly distributed at the bottom of the sand filter tank body 1. By fixing the evenly distributed foot supports 7 at the bottom of the sand filter tank body 1, the sand filter tank can be stably placed on the ground, so that it is not easy to collapse due to tilting, and the stability effect is better.
[0035] The working principle of the sand filter tank with a heat-insulating structure: when using the sand filter tank with a heat-insulating structure, the device must first be installed at the required position. By fixing and connecting evenly distributed foot supports 7 at the bottom of the sand filter tank body 1, the sand filter tank can be stably placed on the ground, so that it is not easy to collapse due to tilting, and the stability effect is better. After the installation is completed, sand and gravel can be filled through the feed port 4 on the surface of the sand filter tank. When the sand and gravel inside the sand filter tank need to be supplemented or replaced, the feed port 4 can be opened to pour the sand and gravel into the sand filter tank. The filling is more convenient, and then the water to be filtered can be input into the sand filter tank through the water inlet 3. After passing through the sand and gravel structure and the water filtration system inside the sand filter tank, the filtered water is poured into the water outlet 6. The water is discharged, and the filtering effect is better. At the same time, by turning on the heating device 16, the heating pipe 17 and the heating device 16 can emit heat, and the heat is transported to the inside of the sand filter tank body through the heat-conducting copper tube 18, so that when the sand filter tank is used in a relatively cold environment, the inside is not easy to freeze, and the anti-freezing effect is better. When the sand filter tank is performing the filtering process, the dust-proof top is covered by the cover plate 13 to prevent particles and dust in the air from floating into the sand filter tank, resulting in the need for frequent replacement of sand and gravel inside the sand filter tank, and the dust-proof effect is better. At the same time, the heat insulation board 2 provided on the surface of the sand filter tank body 1 can prevent heat from entering the sand filter tank, so that the inside of the sand filter tank always maintains a relatively normal temperature, and it is not easy to cause accidents due to temperature imbalance, and the heat insulation effect is better.
