The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
Example 1
Referring to fig. 1 to 3, the present embodiment discloses a device 1000 for removing impurities, wherein the device 1000 comprises a rain grate 1100, a carrying filter 1200 and a separable container, so that the separable container can collect impurities and is removed from the rain grate 1100 for easy cleaning, thereby eliminating various drawbacks of on-site cleaning.
The rain grate 1100 is mounted on a drain with an upper surface exposed to the road surface to form an exterior surface and a lower surface opposite the drain. Generally, in the municipal road, the rain grate 1100 can be disposed at the edge of the road, so that the trunk of the municipal road is smoother, and smooth traffic is ensured. The rain grate 1100 can also be arranged in the middle of the road to increase the drainage speed of the road surface so as to prevent the water from accumulating on the road surface, and the effect is very remarkable on the road easy to accumulate water. In the non-municipal road area, the rain grate 1100 can be correspondingly arranged according to actual needs.
The rain grate 1100 has mounting seat holes 1111 through its upper and lower surfaces for mounting the carrying filter cells 1200. In other words, the mount hole 1111 is a through hole, an upper port of which is connected to the road surface, and a lower port of which is opposite to the drain.
The specific construction of the rain grate 1100 is varied. Illustratively, the rain grate 1100 has a carrier wall 1110 and a deflector wall 1120 integrally connected. The mounting holes 1111 are formed in the carrier wall 1110, and structural support for the carrier filter tank 1200 is provided by the carrier wall 1110. The supporting wall 1110 and the guiding wall 1120 may be integrally formed, or may be formed separately and then fixedly connected to form a whole, wherein the fixing connection manner includes welding, nailing, riveting, etc.
The supporting wall 1110 and the guiding wall 1120 have an obtuse included angle, and the guiding wall 1120 extends obliquely upwards from the outer edge of the supporting wall 1110 to form an acute included angle with the horizontal plane, so that the water and impurities of the guiding wall 1120 flow obliquely downwards to the mounting seat hole 1111 of the supporting wall 1110 under the driving of the dead weight, so as to concentrate and filter the impurities.
Wherein the carrier wall 1110 is maintained opposite the drain for drainage diversion. Illustratively, the deflector wall 1120 is also maintained opposite the drain and has at least one drain grid aperture 1121. The drain holes 1121 penetrate the upper and lower surfaces of the guide wall 1120 to directly guide the drain water, thereby increasing the drainage capacity of the rain grate 1100. The shape of the drain grid hole 1121 is determined according to actual needs, such as square holes, round holes, rectangular grid holes, elliptical holes, or other shaped holes. When the number of the drain holes 1121 is plural, the array of the drain holes 1121 is disposed on the guide wall 1120.
The loading wall 1110 may be inclined to the horizontal or may be horizontally disposed. Illustratively, the included angle between the bearing wall 1110 and the horizontal plane is smaller than the included angle between the guide wall 1120 and the horizontal plane, so that the water flow and the impurities gradually decelerate on the upper surface of the bearing wall 1110 and accurately fall into the separable container of the mounting seat hole 1111, thereby improving the efficiency of collecting the impurities and avoiding the overshoot and scattering of the impurities contained in the water flow.
The carrying filter 1200 is used to carry the separable container and has the necessary drainage and diversion capability. The carrying filter 1200 is fixedly disposed in the mounting hole 1111 and is reliably connected to the rain grate 1100 (which may be specifically the carrying wall 1110 therein). In other words, the load cell 1200 is embedded within the mount hole 1111 and remains fixed with the mount hole 1111.
It will be appreciated that the load cell 1200 has a cell body configuration. For example, the channel structure includes an annular peripheral wall and a bottom wall sealed at one end of the annular peripheral wall. The annular shape of the annular peripheral wall is determined according to practical needs, and includes square, circular, elliptical or other polygonal shapes. It will be appreciated that the annular peripheral wall and the bottom wall described above are both side walls of the load cell 1200.
The opening of the trough body structure is arranged at the upper end to form an extraction notch 1210. In other words, the extraction notches 1210 are located on the upper surface of the carrying filter tank 1200. Meanwhile, at least one side wall of the bearing filter tank 1200 is provided with a water filtering hole 1220, so that the tank body structure can be used for water permeability and diversion. The drainage apertures 1220 may be one to a plurality, and the array is distributed on the sidewall and is opposite to the drainage channel. The shape of the drainage apertures 1220 is determined according to actual needs, including square apertures, round apertures, rectangular grid apertures, elliptical apertures, or other shaped apertures. Illustratively, the annular peripheral wall and the bottom wall of the carrying filter 1200 are provided with water filtering holes 1220, respectively, for multi-point water drainage to increase the water drainage capacity.
The support filter 1200 may be integrally formed into the mounting hole 1111 or may be separately formed and then mounted and secured to the latter. In the latter form, the connection between the load cell 1200 and the mounting pocket 1111 may be achieved in a variety of ways, such as welding, stapling, riveting, and the like.
Illustratively, the end of the mount hole 1111 has a stepped slot 1112 and the peripheral side of the extraction slot 1210 has a connection flange 1230. The step groove 1112 is recessed from the end of the mounting hole 1111, and the connection flange 1230 is a flange structure extending outward from the outer peripheral side of the extraction groove 1210. The connecting flange 1230 is embedded in the step groove 1112 to form an embedded connecting structure, so that the surface is kept flat.
The relative positions of the carrying filter 1200 and the rain grate 1100 are determined according to actual needs.
Illustratively, the upper end surface of the carrying filter 1200 does not exceed the upper surface of the rain grate 1100, so that the impurity-removing and water-draining device 1000 has a flat appearance surface, and the road is ensured to be flat and the bumping obstruction is prevented.
Illustratively, the lower end of the carrying filter 1200 is below the lower surface of the rain grate 1100. In other words, the lower end of the carrying filter tank 1200 extends downward outside the rain grate 1100, thereby increasing the capacity of the tank structure, improving the impurity removal and storage capacity of the impurity removal and drainage device 1000, reducing the cleaning frequency and labor burden, and achieving remarkable convenience.
The separable container is used for collecting sundries and can be taken down from the rain grate 1100 for easy cleaning. Specifically, the separable container is slidably inserted into and removed from the extraction notch 1210 of the carrying filter tank 1200, so as to be sleeved in the tank body of the carrying filter tank 1200 or separated from the tank body of the carrying filter tank 1200.
The detachable receptacle may be implemented in a number of different forms. In one to simple manner, the separable receiver may be implemented as a buoyancy tank having a carrying handle 1330, which is extremely simple in construction. The shape of the buoyancy tank is adapted to the inner cavity in the carrying filter tank 1200, when sundries enter the carrying filter tank 1200 along with water flow, the sundries are wound or contained on the surface of the buoyancy tank and do not slide down any more, and after the buoyancy tank is received, the sundries are taken out together with the buoyancy tank by an operator, so that cleaning is realized.
Illustratively, the separable receiver has a channel configuration, for example, comprising an annular peripheral wall and a bottom wall sealed at one end of the annular peripheral wall, as the separable filter cell 1300. The annular shape of the annular peripheral wall is determined according to practical needs, and includes square, circular, elliptical or other polygonal shapes. It will be appreciated that the aforementioned annular peripheral wall and bottom wall are both side walls of the separable filter cell 1300.
The opening of the channel structure is arranged at the upper end to form a impurity removing notch 1310. In other words, the impurity removal slot 1310 is located on the upper surface of the separable filter tank 1300. Meanwhile, at least one side wall of the separable filter tank 1300 is provided with a filter flow hole 1320, so that the tank body structure can be used for water permeability and flow guide. The drainage apertures 1220 may be one to plural, and are distributed on the sidewalls in an array. The specific shape of the drainage apertures 1320 is determined according to actual needs, including square apertures, round apertures, rectangular grid apertures, elliptical apertures, or other shaped apertures. Illustratively, the annular peripheral wall and the bottom wall of the separable filter tank 1300 are provided with filter holes 1320, respectively, to increase drainage capacity by multi-point drainage.
Wherein, the separable filter tank 1300 is provided with a carrying handle 1330 on the impurity removing notch 1310, so that the operator can extract and take the separable filter tank 1300. Meanwhile, the opening surfaces of the impurity removing slots 1310 are partitioned by the carrying handles 1330 in the horizontal plane, so that the single opening is prevented from being too wide to prevent wheels or pedestrians from falling down. The carrying handle 1330 has a certain carrying capacity, and will not break the structure under the pressure of the vehicle and the pedestrian.
Illustratively, a carrying handle 1330 is disposed above and connected to the impurity removal slot 1310. In other words, the carrying handle 1330 spans the impurity removal slot 1310 and is located outside the impurity removal slot 1310, so as to form a bridge structure. Therefore, a gap is formed between the carrying handle 1330 and the impurity removing notch 1310 along the vertical direction, so that the lateral passing capability of the impurity removing notch 1310 is increased, impurities, particularly medium-sized and large-sized impurities, can enter the impurity removing notch 1310 from the lateral direction, and are further contained in the separable filter tank 1300, the purposes of impurity removal and storage are achieved, and the impurities are prevented from being wound on the rainwater grate 1100.
Illustratively, the load cell 1200 has a lower drain rate than the water inlet rate, forming a water flow buffer at its bottom. Based on the difference between the water supply and drainage speeds, when the inflow water flow is large (for example, exceeds the drainage limit), the water entering the bearing filter tank 1200 cannot be timely drained, and the water flow is partially temporarily buffered in the water flow buffer area, so that the water level of the water flow buffer area is gradually increased, and the separable container can be floatably kept on the buffered water surface of the water flow buffer area.
For example, when the separable container is the separable filter tank 1300, the separable filter tank 1300 is floatably held on the water surface of the water flow buffer area, and floats up in synchronization with an increase in the water level of the water flow buffer area. When the inflow water flow is larger, the pavement water quantity is higher, and the distribution range of sundries in the vertical direction is wider. The floating separable filter tank 1300 enables the impurity removing notch 1310 to float synchronously, so that the vertical distribution range of impurities is covered, and the impurities are prevented from escaping and leaking. Further, the carrying handle 1330 floats up synchronously, so that the gap between the carrying handle 1330 and the impurity removing slot 1310 floats up synchronously, and impurities enter the separable filter tank 1300 from side direction rapidly. Illustratively, the separable filter cell 1300 is provided with a float to increase the floating capacity of the separable filter cell 1300.
For another example, when the separable container is a buoyancy tank, the buoyancy tank can directly float along with the lifting of water, and always keeps on the water level of the water flow slow-accumulating area, and the container can be kept by contacting sundries for the first time.
Illustratively, the drainage apertures 1220 are positioned opposite the drainage apertures 1320, shortening the flow path length to accelerate drainage. In other words, the drainage apertures 1220 are disposed on the sidewall of the carrier filter cell 1200 facing the drainage apertures 1320, and the drainage apertures 1320 are disposed on the sidewall of the separable filter cell 1300 facing the drainage apertures 1220.
The impurity removal and drainage device 1000 is briefly described as follows.
Before use, the rain grate 1100 is installed on the ground to cover the drain. The separable filter cell 1300, which remains clean, is embedded within the carrier filter cell 1200, ensuring a relatively fixed position. When water flow occurs on the road surface, the water flow is mixed with impurities to flow to the mounting seat hole 1111 and enter the inner cavity of the separable filter tank 1300 from the impurity removing notch 1310 of the separable filter tank 1300.
The water flows through the filtering holes 1320 and 1220 and falls into the drainage channel, so as to achieve the purpose of drainage. Impurities entrained in the water flow are blocked and filtered by the filtering holes 1320 and stay in the inner cavity of the separable filter tank 1300, so that the purposes of impurity removal and impurity collection are achieved. Illustratively, as the amount of road surface water increases, the carrying filter 1200 forms a water flow buffer area at the bottom thereof, so that the separable filter 1300 floats up synchronously with the increase of the water amount of the water flow buffer area, and is suitable for the impurity removal and storage requirements under different road surface water amounts.
When debris collected by separable filter element 1300 has reached the armed capacity, an operator removes separable filter element 1300 from carrier filter element 1200 via carrier handle 1330 and transfers it to a safe working position for cleaning. At the same time, the operator places the clean separable filter cell 1300 from the extraction slot 1210 into the cavity of the load filter cell 1200, maintaining continuous use.
Example 2
Referring to fig. 4 to 6 in combination, the present embodiment discloses a device 1000 for removing impurities, which is different from embodiment 1 in that the rain grate 1100 further includes a receiving arm 1130. The receiving arm 1130 is formed on a side of the mounting seat hole 1111 near the guide wall 1120, the receiving arm 1130 extends downward from the lower surface of the carrying wall 1110, and the drain hole 1121 penetrates the receiving arm 1130 and communicates with the mounting seat hole 1111.
In other words, the receiving arm 1130 is held opposite the lower surface of the guide wall 1120 and the connection therebetween is achieved by a plurality of vertical connecting arms. The end of the drain grid hole 1121 is formed between the adjacent vertical connecting arms, so that the water guided by the guide wall 1120 can enter the bearing filter tank 1200 from the end of the drain grid hole 1121, and the impurity removal coverage area of the water flow is increased. Illustratively, the receiving arm 1130 is combined with a plurality of vertical connecting arms to form a comb-like structure with an opening facing upward.
Illustratively, a side wall of the load filter cell 1200 proximate the deflector wall 1120 overlaps the receiving arm 1130 with an upper surface thereof in communication with the extraction slot 1210, thereby forming a first lateral cutout 1250. The first lateral opening 1250 is recessed downward from the extraction notch 1210, so that the water flowing in from the comb-shaped structure smoothly enters the bearing filter tank 1200, and multi-directional storage and impurity removal are realized.
