Description

Technical Field

[0001] The utility model relates to the technical field of factory building drainage systems, and more specifically, to a factory building roof drainage pipe anti-blocking device. Background Art

[0002] The slag treatment hot pouring room steel structure plant is a house for smelting steel. For better drainage, a drainage system is generally installed. The existing plant roof drainage system, such as Figure 1 As shown, a drain pipe 2 is generally installed under the gutter 1 of the roof, and rainwater is collected in the gutter 1, and then flows from the gutter 1 to the drain pipe 2 to achieve drainage of the factory roof. For the steel structure plant of the slag treatment hot-splashing room, the slag treatment plant is located near the mountains and forests. Affected by birds and wind, there are many dead branches, leaves, and weeds on the roof of the hot-splashing room. Under the effect of rain scouring, dead branches and weeds are easily stuck in the drain pipe, making drainage unsmooth, and even blocking the pipe. At the same time, the slag treatment production site is dusty, resulting in a lot of dust collection on the roof of the hot-splashing room. Under the effect of rain scouring, dust is easily deposited at the bend of the pipe and condensed on the inner wall of the pipe, causing the inner diameter of the pipe to continue to shrink and block the pipe. The metal colored steel tiles on the roof and the steel structure gutter are easily affected by oxidation and corrosion, and the surface paint is easy to fall off, forming hard paint blocks. The paint blocks and the fallen block oxides are easily washed into the pipe by rain and remain at the bend of the pipe, resulting in poor drainage and even blocking the pipe.

[0003] Due to its complex structure, such as an exhaust tower on the top of the hot pouring room roof, a canopy on the top of the exhaust tower, rain eaves on the side of the hot pouring room, and a guard span at the bottom of the rain eaves, the drainage pipes are irregularly distributed, with many bends. In addition, due to the long distance, it is difficult to locate the blockage point once it is blocked.

[0004] Therefore, it is urgent to design a factory roof drainage pipe anti-blocking device to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a factory roof drainage pipe anti-blocking device in view of the above-mentioned deficiencies in the prior art, which can effectively intercept debris, avoid drainage pipe blockage, and save manpower and material resources for drainage pipe maintenance.

[0006] The technical solution of the utility model is as follows: a device for preventing drainage pipes on factory roofs from being blocked, comprising an isolation chamber, a drainage pipe being connected to one side of the upper portion of the isolation chamber, an interception net surrounding the water inlet of the drainage pipe being provided in the isolation chamber on one side of the drainage pipe, a water inlet hopper being provided on the top of the isolation chamber, the water inlet hopper being located directly below the gutter, a separation assembly for separating impurities being detachably provided at the lower portion of the isolation chamber, a sealing door being detachably installed on the front side of the isolation chamber corresponding to the separation assembly, a sewage pipe being provided on one side of the bottom of the isolation chamber, the sewage pipe being connected to the drainage pipe, and a drainage valve being provided on the sewage pipe.

[0007] As a further improvement, the separation assembly includes a first baffle and a second baffle, which are both slidably inserted in the isolation chamber, and are both inclined, and are arranged alternately. A water flow channel is formed between one end of the first baffle and the second baffle and the inner wall of the isolation chamber, and a first filter screen is provided at one end of the first baffle near its corresponding water flow channel, and a second filter screen is provided at one end of the second baffle near its corresponding water flow channel, and a filter hole size of the first filter screen is larger than the filter hole size of the second filter screen, and the sewage pipe is located below the second baffle.

[0008] Furthermore, the first filter is movably inserted in the first baffle, and a limit block is provided on the second baffle, and the limit block is attached to the rear side of the first filter; the second filter is movably inserted in the second baffle, and a limit block is provided at the bottom of the inner wall of the isolation chamber, and the limit block is attached to the rear side of the second filter.

[0009] Furthermore, a magnet block is provided on the top of the second baffle.

[0010] Furthermore, the first baffle plate is connected to the second baffle plate via a plurality of support rods, a support rod is provided at the bottom of the second baffle plate, and the bottom of the support rod is attached to the bottom of the inner wall of the isolation chamber.

[0011] Furthermore, the sealing door is connected to the isolation chamber by bolts, and a sealing ring is provided between the sealing door and the isolation chamber.

[0012] Furthermore, the sewage pipe is a transparent pipe.

[0013] Beneficial Effects

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] 1. The utility model of the factory roof drainage pipe anti-blocking device adds an isolation chamber with an interception net between the gutter and the drainage pipe. After rainwater enters the isolation chamber, particulate matter can be settled at the bottom of the isolation chamber, while floating objects such as leaves and branches float on the water surface and are intercepted by the interception net. Water is discharged from the drainage pipe by overflow, which can effectively intercept debris. The overflow method can further improve the filtering effect, avoid the blockage of the drainage pipe, and save manpower and material resources for drainage pipe maintenance.

[0016] 2. The utility model of the factory roof drain pipe anti-blocking device arranges a separation component at the bottom of the isolation chamber. When cleaning the isolation chamber, the drain valve can be opened to discharge the water in the isolation chamber through the drain pipe. Due to the filtering of the two filter screens in the separation component, the debris cannot be discharged directly, and the problem of drain pipe blockage will not be caused. After the water in the isolation chamber is drained, the sealing door can be opened and the separation component can be taken out for cleaning, which is very convenient for disassembly and maintenance.

DETAILED DESCRIPTION

[0022] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0023] See also Figure 2-4The utility model discloses a device for preventing rainwater from being blocked on the roof of a factory building, comprising an isolation chamber 3, which is a shell with a hollow structure. One side of the upper part of the isolation chamber 3 is connected to the drain pipe 2, and the drain pipe 2 is installed on one side of the upper part of the isolation chamber 3 to form overflow drainage. An interception screen 4 is arranged in the isolation chamber 3 on one side of the drain pipe 2 to surround the water inlet of the drain pipe 2 to prevent floating objects from entering the drain pipe 2. An inlet bucket 5 is arranged on the top of the isolation chamber 3, which is located just below the gutter 1, so that rainwater can enter the isolation chamber 3 conveniently. A separation component for separating impurities is detachably arranged at the lower part of the isolation chamber 3. The detachable separation component is convenient for disassembly and maintenance. A sealing door 6 is detachably installed on the front side of the isolation chamber 3 corresponding to the separation component. The detachable sealing door 6 is convenient for disassembly and maintenance. A sewage pipe 7 is arranged on one side of the bottom of the isolation chamber 3, which is connected with the drain pipe 2, and a drainage valve 8 is arranged on the sewage pipe 7. When the isolation chamber 3 is cleaned, it is convenient to discharge the water inside the isolation chamber 3.

[0024] The utility model provides a device for preventing the drainage pipe on the factory roof from being blocked, by adding an isolation chamber 3 with an interception screen 4 between the gutter 1 and the drainage pipe 2. After rainwater enters the isolation chamber 3, particulate matter can be settled at the bottom of the isolation chamber 3, while floating objects such as leaves and branches float on the water surface and are intercepted by the interception screen 4. Water is discharged from the drainage pipe by overflow, which can effectively intercept debris. The overflow method can further improve the filtering effect, avoid the blockage of the drainage pipe, and save manpower and material resources for drainage pipe maintenance.

When rainwater falls from the water inlet hopper 5, due to the obstruction of the first baffle 9, it cannot impact the sediment at the bottom of the isolation chamber 3, and therefore the sediment at the bottom will not be lifted up, thereby further ensuring the filtering effect. A first filter screen 12 is provided at one end of the first baffle plate 9 close to its corresponding water flow channel 11, and a second filter screen 13 is provided at one end of the second baffle plate 10 close to its corresponding water flow channel 11. The filter hole size of the first filter screen 12 is larger than the filter hole size of the second filter screen 13. The sewage pipe 7 is located below the second baffle plate 10. The setting of the two filter screens can prevent debris from being discharged from the sewage pipe 7, thereby preventing the drain pipe 2 from being blocked.

[0026] The factory roof drain pipe anti-blocking device of the present invention is configured with a separation component at the bottom of the isolation chamber 3. When the isolation chamber 3 is cleaned, the drain valve 8 can be opened to discharge the water in the isolation chamber 3 through the drain pipe 2. Due to the filtering of the two filter screens in the separation component, the debris cannot be discharged directly, and the problem of drain pipe blockage will not be caused. After the water in the isolation chamber 3 is drained, the sealing door 6 can be opened and the separation component can be taken out for cleaning, and the disassembly and maintenance are very convenient.

[0027] Preferably, the first filter 12 is movably inserted in the first baffle 9, and a limit block 14 is provided on the second baffle 10, and the limit block 14 is attached to the rear side of the first filter 12 to avoid the problem of the first filter 12 being deformed by the impact of the water flow; the second filter 13 is movably inserted in the second baffle 10, and a limit block 14 is provided at the bottom of the inner wall of the isolation chamber 3, and the limit block 14 is attached to the rear side of the second filter 13 to avoid the problem of the second filter 13 being deformed by the impact of the water flow. In this embodiment, both filters are detachable, which makes it convenient to disassemble them separately for cleaning or replacement, and the disassembly and maintenance are very convenient.

[0028] Preferably, a magnet block 15 is further provided on the top of the second baffle 10 , and the magnet block 15 can absorb iron filings for the purpose of recycling and reuse, and can also avoid the problem of clogging of the drain pipe 2 .

[0029] Preferably, the first baffle plate 9 and the second baffle plate 10 are connected by a plurality of support rods 16, so that the first baffle plate 9 and the second baffle plate 10 form a whole, which facilitates the removal of the entire separation assembly. A support rod 16 is provided at the bottom of the second baffle plate 10, and the bottom of the support rod 16 is attached to the bottom of the inner wall of the isolation chamber 3, thereby supporting the entire separation assembly.

[0030] Preferably, the sealing door 6 is connected to the isolation chamber 3 by bolts to achieve a detachable connection of the sealing door 6 , and a sealing ring is provided between the sealing door 6 and the isolation chamber 3 to ensure the sealing of the isolation chamber 3 .
