Abstract

The utility model relates to the field of pulse multi-layer composite filter material biological filter, and specifically to a pulse water distributor for pulse multi-layer composite filter material biological filter, including a water distributor body, a main body for carrying sewage to perform pulse water distribution. The utility model is provided with a water inlet tank, a pressure water pump, an inlet and outlet water pipe, a torrent pipe ring, a pulse nozzle, a pulse bell and a siphon pipe.

Description

Technical Field

[0001] The utility model relates to the field of pulse multi-layer composite filter material biological filter, in particular to a pulse water distributor used for a pulse multi-layer composite filter material biological filter. Background Art

[0002] The pulse biofilter is a water treatment technology developed on the basis of the biological trickling filter and belongs to the ordinary biological filter. The pulse multi-layer composite filter media biological filter does not require aeration, natural ventilation and oxygen supply, has a high hydraulic load, occupies a small area, and is resistant to shock loads. It can be used for rural domestic sewage treatment with a slightly larger water volume. It adopts a siphon pulse water distribution method, which can not only maintain the filter tank to operate at a low average load and ensure the smooth completion of the nitrification reaction in the filter tank, but also ensure that part of the aging biofilm is instantly flushed away during water distribution, thereby maintaining a highly active biofilm, solving the problems of traditional biological filters being prone to clogging, growth of pool flies, and generation of odors. The siphon pulse water distribution method requires the use of a pulse water distributor, which is a high-efficiency water distribution equipment, mainly used in anaerobic tank hydrolysis processes. The use of a pulse water distributor allows the microorganisms in the filter tank to come into more complete contact with the organic matter in the sewage, thereby improving the treatment efficiency of the biological filter.

[0003] After searching, a siphon type pulse water distributor with publication number CN205603313U specifically discloses a siphon type pulse water distributor, including a pulse tank, a first water inlet pipe is arranged on the side of the pulse tank, a central pipe is arranged in the pulse tank, a siphon cover is sleeved on the top of the central pipe, the siphon cover is fixed on the pulse tank through siphon cover supporting legs, a U-shaped pipe is arranged between the central pipe and the siphon cover, the central pipe passes through the pulse tank and is connected with a buffer exhaust pipe, a second water inlet pipe, a water outlet pipe and an exhaust pipe are arranged in the buffer exhaust pipe. The siphon type pulse water distributor proposed by the utility model utilizes the siphon principle to perform fully automatic water distribution, and realizes continuous water inlet and instantaneous drainage, forming periodic pulse water inlet, and has significant economic and technical benefits.

[0004] When the existing pulse water distributor is used on a pulse multi-layer composite filter biofilter, due to the complex structure of the pulse multi-layer composite filter biofilter, the pulse force generated only by the siphon effect of the pulse water distributor itself during pulse water distribution cannot meet the use requirements of some high-demand pulse multi-layer composite filter biofilters, and the pulse water distributor in the above-mentioned comparative case lacks a method to enhance its own water distribution pulse force. Therefore, insufficient pulse force after long-term use will lead to the inability to evenly spray sewage into the filter, resulting in uneven distribution of sewage on the filter surface, weakened water flow stirring effect, and the sludge at the bottom of the pool cannot be fully stirred up and mixed with sewage, thereby reducing the treatment efficiency of the filter.

[0005] Therefore, it is necessary to invent a pulse water distributor for a pulse multi-layer composite filter biofilter to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a pulse water distributor for a pulse multi-layer composite filter biofilter, which realizes the rotation of sewage through a water inlet tank, a pressure water pump, an inlet and outlet pipe, a rapid flow pipe ring, a pulse nozzle, a pulse bell and a siphon pipe, which can enhance the power of the water flow, thereby helping to take away the air in the main outlet pipe more quickly, thereby increasing the vacuum degree to a certain extent, and then cooperating with the vacuum degree of the siphon effect produced by the siphon pipe on the pulse bell, the two can be combined to correspondingly enhance the pulse force of the pulse water distributor, and the enhanced pulse force can make the sewage sprayed into the filter tank evenly, so that the sewage is evenly distributed on the filter material surface, and the water flow with sufficient pulse force can fully stir up the sludge at the bottom of the pool and mix it with the sewage, thereby improving the filtration efficiency. The effect of improving the treatment efficiency of the pool is to solve the problem that when the pulse water distributor in the prior art is used on the pulse multi-layer composite filter material biological filter, due to the complex structure of the pulse multi-layer composite filter material biological filter, the pulse force generated only by the siphon effect of the pulse water distributor itself during pulse water distribution cannot meet the use requirements of some high-demand pulse multi-layer composite filter material biological filter, and the pulse water distributor in the above-mentioned comparative case lacks a method to enhance its own water distribution pulse force. Therefore, the insufficient pulse force after long-term use will lead to the sewage not being evenly sprayed into the filter tank, resulting in uneven distribution of sewage on the filter material surface, weakened water flow stirring effect, and the sludge at the bottom of the pool cannot be fully stirred up and mixed with sewage, thereby reducing the treatment efficiency of the filter tank.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The utility model provides Figure 1-5 The pulse water distributor shown is used for a pulse multi-layer composite filter material biological filter, comprising a water distributor body 1, which is a main body for carrying sewage to perform pulse water distribution work;

[0028] A cover 5 is arranged above the water distributor body 1 and is used to close the water distributor body 1. A water inlet tank 6 is arranged above the cover 5. A water inlet port 7 is provided on the top of the water inlet tank 6. A pressurized water pump 8 is fixedly installed outside the water inlet tank 6. An inlet and outlet water pipe 9 is fixedly installed at one end of the pressurized water pump 8. A rapid flow pipe ring 10 is fixedly installed at the other end of the inlet and outlet water pipe 9. A pulse nozzle 11 is arranged inside the rapid flow pipe ring 10.

[0029] A pulse bell 12 is arranged inside the water distributor body 1 for performing a siphon effect, and a main water outlet pipe 13 is arranged inside the pulse bell 12. A mounting flange 14 is fixedly installed at the bottom of the main water outlet pipe 13, and a main water distribution pipe 15 is fixedly installed inside the mounting flange 14. A siphon pipe 16 is arranged outside the pulse bell 12. After the water flow increases to a certain pressure, it cooperates with the multiple groups of pulse nozzles 11 tilted downward by the rapid flow pipe ring 10, so that a vortex is formed inside the water distributor body 1 after the sewage is sprayed out. The rotating sewage will enhance the power of the water flow, thereby helping to take away the air in the main water outlet pipe 13 faster, thereby increasing the vacuum degree to a certain extent, and then cooperate with the vacuum degree of the siphon effect generated by the siphon pipe 16 on the pulse bell 12. The two are combined to correspondingly enhance the pulse force of the pulse water distributor. The enhanced pulse force can allow the sewage to be evenly sprayed into the filter tank, so that the sewage is evenly distributed on the filter material surface.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a support frame 2 is fixedly installed at the bottom of the water distributor body 1, and a mounting seat 3 is fixedly installed at the bottom of the support frame 2. A positioning bolt 4 is penetrated above the mounting seat 3. The structure of the support frame 2, the mounting seat 3 and the positioning bolt 4 is simple and easy to operate, which makes it convenient to install the pulse water distributor above different pulse multi-layer composite filter material biological filters to complete the pulse water distribution of sewage. The cover 5 is movably connected to the water distributor body 1, and the water inlet tank 6 is fixedly connected to the cover 5. The water distributor body 1 is closed by the cover 5 to facilitate the installation and use of the water inlet tank 6. The number of pulse nozzles 11 is set to eight, and the eight pulse nozzles 11 are distributed in a circular array on the rapid flow pipe ring 10. The rapid flow pipe ring 10 is inclined downward with multiple groups of pulse nozzles 11, so that the sewage forms a vortex inside the water distributor body 1 after being sprayed out, thereby increasing the vacuum degree of the pulse water distributor.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, the number of siphon pipes 16 is set to six, and the six siphon pipes 16 are distributed in a circular array on the pulse bell jar 12. The siphon pipes 16 give the pulse bell jar 12 the original vacuum degree through the siphon effect to ensure the normal operation of the pulse water distributor. An auxiliary water outlet pipe 17 is fixedly installed on the outside of the main water outlet pipe 13, and an electromagnetic control valve 18 is fixedly installed on one end of the auxiliary water outlet pipe 17, and an auxiliary water distribution pipe 19 is fixedly installed on the other end of the electromagnetic control valve 18. A plurality of groups of auxiliary water outlet pipes 17 and auxiliary water distribution pipes 19 are arranged outside the main water outlet pipe 13. In this way, the water distribution range and water distribution speed of the pulse water distributor can be expanded according to different sizes and usage requirements of the pulse multi-layer composite filter material biological filter, thereby improving the working efficiency of the pulse multi-layer composite filter material biological filter to a certain extent.

[0032] The working principle of the utility model is as follows: firstly, the external power supply is turned on, and a suitable installation position is selected above the pulse multi-layer composite filter material biological filter tank where the pulse water distributor is currently required to be installed, and the pulse water distributor is installed above different pulse multi-layer composite filter material biological filters through the support frame 2, the mounting seat 3 and the positioning bolt 4, and then the external sewage pipe is inserted into the water inlet 7 of the water inlet tank 6, so that the sewage can enter the water inlet tank 6 at a uniform speed. At this time, after the preparation work is completed, the switch of the pressure water pump 8 can be turned on, and the pressure water pump 8 can be connected through the inlet and outlet. The water pipe 9 draws out the sewage in the water inlet tank 6, and then transports it to the rapid flow pipe ring 10, and sprays it out from the pulse nozzle 11, which increases the original water flow to a certain extent. Then, in conjunction with the multiple groups of pulse nozzles 11 tilted downward on the rapid flow pipe ring 10, a vortex is formed inside the water distributor body 1 after the sewage is sprayed out. The rotating sewage will enhance the power of the water flow, thereby helping to take away the air in the main water outlet pipe 13 faster, thereby increasing the vacuum degree to a certain extent. Subsequently, as the liquid level inside the water distributor body 1 rises, the siphon pipe 16 fits in the pulse nozzle 11. The outside of the bell jar 12 allows the sewage with a high liquid level in the water distributor body 1 to flow quickly to the siphon pipe 16. The siphon pipe 16 of the fast-flowing water produces a siphon effect on the pulse bell jar 12. In this way, the vacuum degree originally generated by the siphon in the siphon pipe 16 plus the vacuum degree formed by the sewage vortex, the two are combined to correspondingly enhance the pulse force of the pulse water distributor. The enhanced pulse force can allow the sewage to be evenly sprayed into the filter tank, so that the sewage on the filter material surface is evenly distributed. Then, multiple groups of auxiliary water outlet pipes 17 and auxiliary water distribution pipes 19 are arranged outside the main water outlet pipe 13, which can be used according to the According to the different sizes and usage requirements of pulse multi-layer composite filter biofilters, the water output of the auxiliary water distribution pipe 19 is controlled by the electromagnetic control valve 18, thereby expanding the water distribution range and water distribution speed of the pulse water distributor, and improving the working efficiency of the pulse multi-layer composite filter biofilter to a certain extent. Finally, after completing the installation and use of all pulse water distributors according to the above operations, turn off the switch of the pressurized water pump 8, and cut off the external power supply if it is not used for a long time. In this way, the use process of the pulse water distributor for the pulse multi-layer composite filter biofilter is completed.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
