Description

Middle pond filter

Technical field

The utility model relates to the production equipment of water for industrial use, more particularly, relates to a kind of middle pond filter, the impurity that can effectively remove the rotary sieve outer wall of this filter.

Background technology

The water for industrial use of numerous steel-making enterprises is by providing water factory's production and supply for oneself.See also shown in Figure 1, the manufacture water is a dry point 1 with water sources such as river, lakes generally, fetch water by water pump, and by pipeline with in the former water suction one-level treatment system 2, this one-level treatment system comprises intake chamber 3, filter screen chamber 4 and suction chamber 5, former water flow through successively intake chamber 3, filter screen chamber 4 and suction chamber 5 carry out one-level and handle.Pond in the middle of wherein filter screen chamber 4 is called again, pond filter 10 in the middle of inside is provided with, please in conjunction with shown in Figure 2, this filter 10 comprises rotary sieve 11 and flushing hydraulic giant 12,13, rotary sieve 11 is " O " type, interior ancient piece of jade, round, flat and with a hole in its centre smooth surface, outer ancient piece of jade, round, flat and with a hole in its centre surface are provided with several parallel and equally distributed metallic plates 111; Flushing hydraulic giant 13,12 be located at respectively rotary sieve 11 in, outer both sides, outside flushing hydraulic giant 12 comprises water pipe 121, nozzle 122 and joint 123, water pipe 121 is a steel pipe, the sealing of one end, the other end is provided with joint 123, and be connected and fixed with joint 123 1 ends, water pipe 121 sidepieces are provided with several aperture (not shown)s, line and water pipe 121 axis parallels between several apertures, be equipped with nozzle 122 on each aperture, and be connected with nozzle 122 1 ends and communicate, nozzle 122 other ends are towards rotary sieve 11 outer walls, and parallel to each other and nozzle 122 is the oblique angle with water pipe 121 axial lines between the nozzle 122; The water supply line 141 of the other end of joint 123 and high-pressure pump 14 controls is connected and communicates.During work, rotary sieve 11 bottoms are sunk in the water in filter screen chamber 4 (middle pond), drive the circulating water effect by rotation, foreign material in the former water 6 (waste paper, plastic products etc.) are attached on rotary sieve 11 outer walls, and take the water surface out of, water after will filtering is simultaneously brought suction chamber 5 into, and is delivered to next procedure by water pump 7.Simultaneously, flushing hydraulic giant 13, the 12 ejection water under high pressures of the inside and outside both sides by rotary sieve 11, wash rotary sieve 11 outer walls at (injection direction as shown by arrows), and foreign material 6 are dashed in the groove 15 that drops down onto flushing hydraulic giant 12 bottoms, the outside, finish filtration to former water in the middle pond.

Because outside flushing hydraulic giant 12 is the mode of unidirectional many current flushings, influenced by unidirectional flushing angle, can produce the dead angle, the part position of rotary sieve 11 outer walls can't be washed into, and particularly the foreign material 6 at metallic plate 111 places on the outer wall are difficult to be rinsed clean, thereby be rotated in the pond of suction chamber 5 that filter screen 11 is brought into opposite side, not only increased the weight of the burden of next procedure, and because of the influence of foreign material 6 can cause the water pump shortening in 7 service lifes, and badly influence the system water quality; If foreign material 6 are manually removed, not only time-consuming taking a lot of work, but also have certain potential safety hazard.

The utility model content

The foreign material that clean dead angle, rotary sieve outer wall at the above-mentioned generation that exists in the prior art can't effectively clean, shorten the service life of water pump and the shortcoming of influence system water quality, the purpose of this utility model provides a kind of middle pond filter, this filter apparatus configuration is simple, easy to use, can effectively remove the foreign material of rotary sieve outer wall, guarantee the system water quality.

For achieving the above object, the utility model adopts following technical scheme:

This pond, centre filter comprises rotary sieve and flushing hydraulic giant, the flushing hydraulic giant is located at the inside and outside both sides of rotary sieve respectively, outside flushing hydraulic giant further comprises water pipe, nozzle and joint, nozzle is located on the water pipe, joint is located at water pipe one end, described water pipe is several, and several water pipe one ends all communicate by the joint connection, and the nozzle of adjacent two water pipes is arranged in a crossed manner.

The quantity of described water pipe is at least two.

Parallel to each other and one-tenth distribution up and down between the described water pipe.

The nozzle of described same water pipe is parallel to each other; The residing plane of nozzle of residing plane of the nozzle of described same water pipe and adjacent water pipe is parallel to each other.

In technique scheme, the pond filter comprises rotary sieve and flushing hydraulic giant in the middle of of the present utility model, the flushing hydraulic giant is located at the inside and outside both sides of rotary sieve respectively, outside flushing hydraulic giant further comprises water pipe, nozzle and joint, nozzle is located on the water pipe, and joint is located at water pipe one end, and water pipe is several, several water pipe one ends all communicate by the joint connection, and the nozzle of adjacent two water pipes is arranged in a crossed manner.This filter adopts multidirectional many current that the rotary sieve outer wall is cleaned, and cleans no dead angle, the impurity of rotary sieve outer wall thoroughly can be removed, effect is good, has prolonged the service life of water pump, has improved the system water quality, increase economic benefit, eliminated potential safety hazard.
