Detailed Description
The utility model provides a no jam dredge pump, for making the utility model discloses a purpose, technical scheme and effect are clearer, clear and definite, and it is right that the following refers to the attached drawing and the embodiment of lifting the utility model discloses further detailed description. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
In the description of the present invention, it should be understood that the terms "middle part", "inside", "outside", etc. indicate the position or positional relationship of the present invention based on the drawings, and are only for convenience of description and simplified description. Furthermore, the terms "first", "second", "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.
Referring to fig. 1 and 2, the utility model provides a non-clogging dredge pump, including the pump body 1, the bottom of the pump body 1 is provided with lower casing 2, the periphery of lower casing 2 is provided with filters screen panel 3, be provided with rotary mechanism 4 in the casing 2 down, be provided with the motor in the pump body 1, rotary mechanism 4 with the motor links firmly, rotary mechanism 4's lower extreme is provided with impeller 5, impeller 5's mounted position is higher than filter screen panel 3's lower terminal surface.
As shown in fig. 1 and 3, in practical application, the sewage pump is arranged at the bottom of the sewage tank, when the rotating mechanism 4 works, a vortex is formed around the sewage pump, surrounding garbage and sundries are gathered around the sewage pump, and the filter screen 3 can isolate large garbage and sundries such as broken stones, dead leaves and clods in the sewage tank, so as to prevent the large garbage and sundries from entering the lower shell 2; stirring vane wheel 5 is located the bottom of the pool top in blowdown pond, when silt piles up to stirring vane wheel 5's mounting height, stirring vane wheel 5 follows rotary mechanism 4 and rotates to form the vortex and break up silt, avoid silt to pile up too high jam dredge pump.
In one embodiment, the mesh diameter of the filter screen is 5 cm, and if the mesh diameter is too small, the mesh diameter is easily blocked by sludge, and if the mesh diameter is too large, garbage impurities with large volume can enter the inner cavity of the filter screen.
As shown in fig. 3, further, the rotating mechanism 4 includes a rotating shaft 41 and an impeller 42, one end of the rotating shaft 41 is fixedly connected to the output shaft of the motor, the other end of the rotating shaft is fixedly connected to the stirring impeller 5, and the impeller 42 is disposed on the rotating shaft 41 and located in the cavity of the lower housing 2.
As shown in fig. 2 and 3, a filter screen 6 is further disposed at the lower opening of the lower casing 2, and a side wall of the filter screen 6 abuts against an inner wall of the lower casing 2; after being filtered by the filter screen 3, the sewage is likely to carry partial garbage sundries into the filter screen 3, and the lower shell 2 further filters the garbage sundries through the filter screen 6, so that the garbage sundries are prevented from entering the cavity of the lower shell 2.
Further, the outer diameter of the impeller 42 is larger than the outer diameter of the stirring impeller 5; the ratio of the outer diameters of the stirring impeller 5 and the impeller 42 is 0.5 to 0.67; the size of the impeller 42 affects the water flow rate, which is related to the moving amount of silt, and the larger the size of the impeller 42 is, the larger the amount of silt moved by the impeller is, i.e. the more silt is accumulated, so the stirring impeller 5 needs to be adjusted according to the size of the impeller 42; if the ratio of the outer diameter of the stirring impeller 5 to the outer diameter of the impeller 42 is less than 0.5, the amount of the silt moved by the impeller 42 is greater than the flow rate of the water generated by the stirring impeller 5, so that the effect of the stirring impeller 5 is weakened, and the accumulated silt cannot be scattered in time, thereby increasing the load of the motor; if the ratio of the outer diameter of the stirring impeller 5 to the outer diameter of the impeller 42 is greater than 0.67, the amount of silt moved by the impeller 42 will be much smaller than the flow rate of the water generated by the stirring impeller 5, but because the stirring impeller 5 has a large size, the resistance of silt and water flow will also be large, and therefore the load of the motor is increased.
As shown in fig. 2 to 3, further, the stirring impeller 5 includes at least two stirring blades 51, the stirring blades 51 are circumferentially distributed on the rotating shaft 41, and the stirring blades 51 are inclined toward the lower end surface of the rotating shaft 41; in the embodiment, the stirring impeller 5 is composed of three stirring blades 51, different flow rates can be generated by different numbers of the stirring blades 51, so that the stirring effect is influenced, the stirring blades 51 with different numbers can be selected according to the amount of sludge in the water body, and when the number of the stirring blades 51 is set to be 3, the generated flow rate is larger, so that the stirring impeller is suitable for the water body environment with larger sludge amount; further, the inclination of the agitating blade 51 toward the lower end surface of the shaft rod 41 reduces the resistance to which the agitating blade 51 is subjected during operation, thereby reducing the workload of the motor, and the larger the inclination angle of the agitating blade 51, the more vigorous the agitating effect is produced, thereby enhancing the scattering effect on the sludge.
In one embodiment, the edge of the mixing blade 51 is provided with a blade to provide a certain cutting function to prevent the impurities from being entangled on the rotating shaft 41.
As shown in fig. 3 and 4, further, an installation annular wall 21 is disposed at an upper end of the lower housing 2, a fixed wall 31 is disposed at an upper edge of the filter screen 3, and the filter screen 3 is fixedly connected to the lower housing 2 through the fixed wall 31 and the installation annular wall 21; in one embodiment, the fixed wall 31 and the mounting collar wall 21 are in a bolted relationship.
As shown in fig. 2 and 3, further, a plurality of support columns 22 are circumferentially arranged at the bottom of the lower shell 2; the support post 22 may facilitate the positioning of the dredge pump at the bottom of the sewage tank.
Further, the lower end surface of the support column 22 is flush with the lower end surface of the filter screen 3; when the filter screen cover is installed, no gap is formed between the filter screen cover 3 and the pool bottom, and garbage sundries are prevented from entering the inner cavity of the filter screen cover 3 from the bottom.
Further, the supporting column 22 is fixedly connected with the inner wall of the filtering net cover 3 through an annular reinforcing plate 23; the problem of deformation of the filter screen 3 in the use process is prevented by the annular reinforcing plate 23.
In summary, in practical application, as the sewage pump can attract surrounding garbage impurities when in use, the filtering net cover 3 can isolate larger garbage impurities such as broken stones, dead leaves and clods around the sewage pump, and the garbage impurities are prevented from entering the sewage pump; in addition, when silt piles up to impeller 5's mounting height, impeller 5 can follow rotary mechanism 4 and rotate to form the vortex and break up silt, avoid silt to pile up too high jam dredge pump.
It should be understood that equivalent alterations and modifications can be made by those skilled in the art according to the technical solution of the present invention and the inventive concept thereof, and all such alterations and modifications should fall within the scope of the appended claims.
