Detailed Description
In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and examples. It is to be understood that the embodiments described are some, but not all embodiments of the invention. The specific embodiments described herein are merely illustrative of the invention and are not intended to be limiting. All other embodiments, which can be derived from the description of the embodiments of the present invention by a person skilled in the art, are within the scope of the present invention.
Referring to fig. 1 and 2, the present embodiment provides a water quality sample settling and subpackaging apparatus, including: the water distribution pipe guide device comprises a cylinder body 10, a cover body 20 arranged on the cylinder body 10 and a water distribution pipe guide disc 30 arranged in the cylinder body 10; the distributive pipe guide disc 30 comprises a floating disc 31 and a distributive pipe 32 arranged on the floating disc 31, wherein a water inlet at one end of the distributive pipe 32 is vertically and downwards arranged, and the height position of the distributive pipe is lower than the height position of the floating disc 31 by a preset distance, namely the height position of the water inlet of the distributive pipe 32 is lower than the height position of the floating disc 31, and the distance between the water inlet and the water inlet is a preset value; the water outlet at the other end of the water diversion pipe 32 penetrates through the cylinder 10 and extends to the outer side of the cylinder 10.
Wherein, the barrel 10 has a certain inner space, a top opening, and the cover 20 can cover the top opening for sealing, so as to reduce the contact between the water sample and the outside air and ensure the representativeness of the water sample. The distributive pipe guide disc 30 is used for distributing water, and after the water quality sample sedimentation and distribution device reaches the sedimentation time, the distributive pipe guide disc 30 is used for distributing the water sample in the cylinder 10 to each container to detect the relevant indexes of the water sample. In order to improve the representativeness of water samples, the water at a specified depth below the water surface is extracted during water sample distribution as the best water taking mode, therefore, the shunt pipe guide plate 30 of the embodiment is provided with two parts, namely a floating plate 31 and a shunt pipe 32, the floating plate 31 floats on the water surface in the cylinder 10, a water inlet at one end of the shunt pipe 32 is vertically arranged downwards, the height position of the water inlet is lower than the preset distance of the height position of the floating plate 31, the preset distance is set according to requirements, so that when water is taken through the shunt pipe 32, along with the descending of the water surface in the cylinder 10, a water inlet at one end of the shunt pipe 32 also descends, the water taking position is always kept at the specified depth below the water surface, and therefore the representativeness of the.
To the water sample that needs subside, can take the water and directly subside, also can take the back to subside, because the restriction of water sample check-out time, can subside at the in-process of transportation usually to save time, but jolt takes place easily in the transportation, causes and subsides the effect poor, in order to solve above-mentioned problem, in the quality of water sample settlement partial shipment device that this embodiment provided, still be provided with at least one attenuator 40 in the barrel 10, at least one attenuator 40 is close to bottom setting in the barrel 10. The damper 40 is used to prevent the settled sediment from floating, and in order to improve the settling effect, a plurality of dampers 40 are usually arranged, the plurality of dampers 40 are distributed at intervals up and down, and the density of the damping holes is gradually reduced from top to bottom. As shown in fig. 2, two dampers 40 are provided in the cylinder 10, and preferably, the density of the damping holes of the upper damper 40 is greater than that of the damping holes of the lower damper 40, so that the settling effect is better and the required time is shorter.
Specifically, the damper 40 has a circular plate structure, and a tapered hole is formed therein, and a large opening of the tapered hole faces upward and a small opening faces downward, so that the sediment is likely to enter the small opening side from the large opening side and is unlikely to return to the large opening side from the small opening side.
In a specific embodiment, the bottom of the cylinder 10 is a conical structure, and a sewage outlet is arranged on the side wall of the cylinder 10, the sewage outlet is located at the lowest position of the bottom of the cylinder, and the sewage outlet is provided with a plug 11. The cone-shaped bottom of the barrel is beneficial to gathering and discharging sediments, the sediments are gradually deposited downwards under the action of gravity, and the sediments can be discharged out of the barrel 10 by opening the plug 11.
Referring to fig. 1, in order to facilitate the dispensing, the water quality sample settling and dispensing device further includes a siphon 50, and the siphon 50 can be communicated with the water outlet of the water diversion pipe 32 to form siphon when the water is diverted. Therefore, the water sample in the cylinder 10 can be taken out without power parts such as a water pump and the like.
Further, in order to avoid the backflow of water, the siphon 50 is provided with a one-way valve 51 for controlling the water flow direction, and the one-way valve 51 can control the water flow direction to avoid the backflow of the water sample. The water flow can also be controlled to stop or start by the check valve 51. The siphon tube 50 may be hung on the bowl 10 when not in use, as shown in fig. 1.
Further, in the present embodiment, a timer 21 is provided on the lid body 20, and the timer 21 is used to control the settling time. The timer 21 may be disposed at other positions as required, as long as the position where the timer 21 displays time is convenient to view.
In a specific embodiment, a pressure relief valve 22 is disposed on the cover 20, and the pressure relief valve 22 is used for controlling the air pressure balance inside and outside the cylinder 10. The pressure relief valve 22 can not only control the air pressure balance inside and outside the cylinder 10, but also achieve the purpose of controlling the water flow speed in the water diversion pipe 32. In the case where the cover 20 is completely sealed with the cylinder 10, air can only enter the cylinder 10 through the relief valve 22, and the amount of air entering the cylinder 10 is equal to the amount of water flowing out of the bypass pipe 32, so the speed of air flowing into the relief valve 22 can affect the water flow speed in the bypass pipe 32.
The inner side of the cover body 20 is provided with a convex structure 23, and the cover body 20 can form a certain pressure into the cylinder body 10 in the process of covering the opening of the cylinder body 10, that is, after the cover body 20 is covered, the pressure in the cylinder body 10 is greater than the atmospheric pressure, so that a water sample in the cylinder body 10 can be naturally discharged outwards when the check valve is opened, and the siphon formation is facilitated. The provision of the raised formation 23 enables greater pressure within the cartridge 10. In the present embodiment, the shape of the projection structure 23 is a conical shape.
In a particular embodiment, the barrel 10 is cylindrical in shape. Other shapes can be designed by those skilled in the art as desired. A buffer pad 12 is provided at the outer bottom of the cartridge 10. The buffer pad 12 can make the barrel 10 more stable to place, and improve the sedimentation effect.
