Description

Technical Field

[0001] The utility model relates to the technical field of water treatment equipment, in particular to a single-opening multi-control electromagnetic mud discharge device for a horizontal flow sedimentation tank. Background Art

[0002] In the entire water treatment process, the sedimentation system is the process with the highest impurity removal rate in the water, and 90% of the impurities are removed by gravity settling to the bottom of the pool. As the most common water treatment structure in the sedimentation process of large and medium-sized water plants, the horizontal flow sedimentation station has the characteristics of simple structure, strong ability to cope with water load, and stable sedimentation effect. The precipitated turbidity is respectively in the flocculation reaction section and the sedimentation section. The sludge discharge in the flocculation reaction section is controlled by a solenoid valve, and usually a solenoid valve controls a group of sludge discharge angle valves for sludge discharge.

[0003] If a common magnetic solenoid valve fails to start the mud discharge angle valve, it needs to be replaced immediately to ensure production. Each solenoid valve is connected to four PPR pipes, and the pressure water enters the solenoid valve to control the opening and closing of the angle valve, thereby completing the mud discharge work. Since the sedimentation tank is responsible for most of the turbidity removal tasks in water treatment work, it is particularly important to quickly and effectively complete the mud discharge task to ensure the normal and stable operation of the structure. The solenoid valve, as an important control switch for mud discharge work, will appear to be frequently opened and closed. Therefore, the service life of the solenoid valve is usually not very long, and it must be replaced in time to meet production needs. The start and stop of the solenoid valve depends on the pressure water, and the pressure water main pipe is laid from front to back along the sedimentation tank. Each additional solenoid valve increases the risk of failure of the solenoid valve and leakage. Once this risk occurs, the entire mud discharge system cannot be activated. At the same time, with the increase in the service life of the pressure water pipe and the influence of the perennial humid environment in the water treatment structure workshop, the pipeline is often damaged or leaking, which makes the local head loss of the pressure water large. The increase in head loss in the pressure water pipeline will directly lead to the inability of some solenoid valves to open and close the mud discharge angle valve normally. If the angle valve cannot be opened, it will affect the normal mud discharge of the sedimentation tank. If it cannot be closed in time, precious water resources will be wasted. Utility Model Content

[0004] The utility model aims to provide a single-opening multi-control electromagnetic mud discharge device for a horizontal flow sedimentation tank to solve the problems raised in the background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A single-open multi-control electromagnetic mud discharge device for a horizontal flow sedimentation tank comprises a four-way electromagnetic valve, on which a water inlet pipe connected to the inlet of the sedimentation tank pressure water main pipe, a drainage pipe connected to the mud discharge channel outlet and a pressure water output pipe are respectively provided, and the pressure water output pipe is respectively connected to an array of mud discharge angle valves connected in parallel through a pressure pipeline;

[0007] Each group of mud discharge angle valves is connected through a tee, and elbows are provided at the inlet and outlet of the farthest mud discharge angle valve.

[0008] Preferably, the pressure water output pipe is connected to three or four groups of mud discharge angle valves connected in parallel through pressure pipelines.

[0009] The working principle of the utility model is:

[0010] The pool of the horizontal flow sedimentation station structure is long, and more mud discharge pipes are pre-buried at the bottom of the pool. Therefore, the entire mud discharge section is usually equipped with a large number of mud discharge angle valves, which are opened and closed by the solenoid valve. In order to improve the working efficiency of the mud discharge section, a single-opening multi-control electromagnetic mud discharge valve is designed. According to the water pressure when the pressure water is working normally, this single-opening multi-control electromagnetic mud discharge valve can drive the start and stop of three groups of mud discharge angle valves at the same time under the premise of ensuring safe production. The principle of this device is mainly to change the path of the pressure water branch pipe passage that opens the mud discharge valve so that the three groups of mud discharge gates are controlled by one solenoid valve, that is, the three groups of mud discharge angle valves are connected in series on this pressure water path. When the device is powered on, the three groups of mud discharge angle valves connected in series by the pressure water branch pipe will be opened in sequence from near to far from the solenoid valve to discharge mud, and will be closed in sequence in the above order after power failure.

[0011] The beneficial effects of the utility model are:

[0012] (1) The utility model single-opening multi-control electromagnetic mud discharge device uses a magnetic suction electromagnetic valve to control three groups of mud discharge angle valves. When the electromagnetic valve fails during the use of the equipment, it needs to be replaced quickly and effectively, which saves costs and reduces the repetitive and mechanical work of maintenance or repair during use, thereby improving resource utilization efficiency.

[0013] (2) The single-opening multi-control electromagnetic mud discharge device of the utility model is not only superior to the single-opening single-control mud discharge form in terms of installation, but also does not require the installation of four-way pipelines. It only needs to connect the two-way pressure water branch pipes of the pressure water start and stop of the three mud discharge angle valves in series. This connection method can reduce the complexity of the connection with the pressure water branch pipe, and at the same time, the installation pipeline can be adjusted according to the specific conditions of the water treatment structure.

[0014] (3) The number and specifications of the mud discharge angle valves connected in parallel in the utility model can be dynamically adjusted according to the water treatment volume, and the utility model has strong adaptability to the treatment process.

[0015] (4) The utility model adopts an overall modular assembly structure, which is easy to install and maintain and has a low manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] like Figure 1 A single-open multi-control electromagnetic mud discharge device for a horizontal flow sedimentation tank is shown, comprising a four-way solenoid valve 1, on which are respectively provided an inlet pipe 2 connected to the inlet of the sedimentation tank pressure water main pipe, a drain pipe 3 connected to the mud discharge channel outlet and a pressure water output pipe 8, the pressure water output pipe 8 is respectively connected to three groups of mud discharge angle valves 6 connected in parallel through a pressure pipeline 7; each group of mud discharge angle valves 6 is connected through a tee 4, and elbows 5 are provided at the inlet and outlet of the farthest mud discharge angle valve 6.

[0020] The pressure water output pipe 8 is connected to three or four groups of mud discharge angle valves 6 connected in parallel through the pressure pipeline 7.

[0021] The four-way solenoid valve used in this device relies on pressure water to realize the start and stop operation of the mud discharge angle valve. One channel water inlet pipe, one channel drainage pipe and two channel pressure water output pipes rely on the alternating work of these two pressure water output pipelines to realize the opening and stopping of the mud discharge gate. During the installation process, four PPR pipes are required. The pressure water main pipe of the sedimentation tank is connected to the solenoid valve water inlet pipe, the outlet of the drainage pipe is directly connected to the mud discharge channel, and the remaining two pressure water output pipes are connected to the mud discharge angle valve to control the opening and closing of the angle valve. During the installation process of a solenoid valve controlling 2 or 3 groups of mud discharge angle valves, it is necessary to connect the two water outlets of a solenoid valve in series with the pipelines of 2 or 3 groups of mud discharge angle valves. This requires adding a PPR tee at the pressure water inlet pipe of each group of angle valves close to the solenoid valve during the installation process. The 90° elbow at the farthest end of the solenoid valve is the last angle valve controlled by pressure water.

[0022] The working principle of this utility model:

[0023] The pool body of the horizontal flow sedimentation station structure is relatively long, and more mud discharge pipes are pre-buried at the bottom of the pool. Therefore, the entire mud discharge section is usually equipped with a large number of mud discharge angle valves, which are opened and closed by the solenoid valve. In order to improve the working efficiency of the mud discharge section, a single-opening multi-control electromagnetic mud discharge valve is designed. According to the water pressure when the pressure water is working normally, this single-opening multi-control electromagnetic mud discharge valve can simultaneously drive the start and stop of three groups of mud discharge angle valves 6 under the premise of ensuring safe production. The principle of this device is mainly to change the path of the pressure water branch pipe passage that opens the mud discharge angle valve 6 so that the three groups of mud discharge angle valves 6 are controlled by a four-way solenoid valve 1, that is, the three groups of mud discharge angle valves 6 are connected in parallel on this pressure water path. When the device is powered on, the three groups of mud discharge angle valves 6 connected in series by the pressure water branch pipe will be opened in sequence from near to far to discharge mud in the order of distance from the four-way solenoid valve 1, and will be closed in sequence in the above order after power failure.

[0024] The utility model single-opening multi-control electromagnetic mud discharge device uses a magnetic solenoid valve to control three groups of mud discharge angle valves. When the solenoid valve fails during the use of the equipment, it needs to be replaced quickly and effectively, which saves costs and reduces the repetitive and mechanical work of maintenance or repair during use, thereby improving resource utilization efficiency. The single-opening multi-control electromagnetic mud discharge device is not only superior to the single-opening single-control mud discharge form in terms of installation, but also does not require the installation of four-way pipelines. It only needs to connect the two-way pressure water branch pipes for starting and stopping the pressure water of the three mud discharge angle valves connected in series. This connection method can reduce the complexity of the connection with the pressure water branch pipe, and at the same time can adjust the installation pipeline according to the specific conditions of the water treatment structure.

[0025] The above are only preferred examples of the present invention. It should be pointed out that for ordinary technicians in this field, under the technical inspiration provided by the present invention, as common knowledge in the mechanical field, other equivalent variations and improvements can be made, which should also be regarded as the protection scope of the present invention.
