Abstract
Description
Technical Field
[0001] The invention relates to the technical field of glass waste water treatment equipment, and in particular to an industrial wastewater circulation filtration system. Background Art
[0002] At present, most companies directly discharge the waste water used for bottle washing, which will waste a lot of water resources. Only a small number of companies collect the waste water from bottle washing for treatment and reuse. However, there are a lot of large particles of impurities such as glass chips in the bottle washing water. When these impurities flow through the fine filtration device, the hardness of the paper filter element inside is less than the hardness of the glass chips themselves, and they are easy to penetrate the paper filter element, making it impossible to filter out impurities such as glass chips. At the same time, it will damage the internal components of the filter and reduce its service life. Summary of the invention
[0003] The purpose of the present invention is to address the deficiencies of the above-mentioned prior art and to provide an industrial wastewater circulation filtration system that can filter out glass debris in glass-containing water without affecting the internal components of subsequent filters.
[0004] The technical solution adopted by the present invention is as follows: An industrial wastewater circulation filtration system comprises a bottle washing device, a wastewater tank, a circulating water pump, a first filter and a second filter which are sequentially connected through pipelines, the outlet end of the second filter is connected to the bottle washing device through a pipeline, a water inlet pipe is arranged on the bottle washing device, a filter screen is covered inside the wastewater tank near the water inlet, a filter element is arranged inside the wastewater tank, a water inlet port and a water outlet port are respectively opened on the filter element, the water outlet port of the filter element is connected to the water outlet of the wastewater tank, and the water outlet of the wastewater tank is arranged on a side wall which is one-third to one-quarter of the height from the bottom of the wastewater tank.
[0005] Furthermore, the first filter is a 5 μm filter and the second filter is a 1 μm filter.
[0006] Furthermore, a plurality of groups of heating rods are arranged in the waste water tank.
[0007] Furthermore, the filter is made of aluminum wire.
[0008] Furthermore, the filter element is a 15 μm stainless steel filter element.
[0009] The beneficial effects of the present invention are: The present invention provides a filter screen and a filter element at the water inlet and the water outlet of the waste water tank, respectively, so that large particles of glass debris can be effectively filtered out. At the same time, the water outlet of the waste water tank is raised, so that the circulating water pump can avoid bringing the glass debris at the bottom of the waste water tank into the filter through the pipeline when absorbing water, thereby preventing damage to the internal components of the filter and affecting the water flow rate. The present invention can effectively recycle water resources through multi-stage filtration, thereby ensuring the treatment efficiency of bottle washing water. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a schematic structural diagram of the industrial wastewater circulation filtration system of the present invention.

[0012] The present invention will be further described below in conjunction with the accompanying drawings: like Figure 1 As shown, the present invention comprises a bottle washing device 1, a waste water tank 2, a circulating water pump 3, a first filter 4 and a second filter 5 which are sequentially connected through pipelines, wherein the first filter 4 is a 5 μm filter, the second filter 5 is a 1 μm filter, the outlet end of the second filter 5 is connected to the bottle washing device 1 through a pipeline, and the bottle washing device 1 is provided with a water inlet pipe 6 for conveying clean water to the bottle washing device 1. A filter screen 7 is provided inside the waste water tank 2 of the present invention and near the water inlet, wherein the filter screen 7 is made of aluminum wire, so that when the waste water containing glass chips after the bottle washing equipment 1 washes the bottles is discharged into the waste water tank 2, it is firstly filtered through the filter screen 7 at the water inlet to filter out some large particles of glass chips.
[0013] The wastewater tank 2 of the present invention is provided with a filter element 8 and a plurality of groups of heating rods 9. The filter element 8 is provided with a water inlet port and a water outlet port respectively. The water outlet port of the filter element 8 is connected to the water outlet of the wastewater tank 2. The filter element 8 is a 15 μm stainless steel filter element. The water outlet of the wastewater tank 2 is arranged on the side wall at a height of one-third to one-quarter of the bottom of the wastewater tank 2. Since the density of glass debris is greater than the density of water, a large amount of small glass debris will still exist in the glass debris water after flowing into the filter screen 7. These small glass debris will directly sink to the bottom of the wastewater tank 2 when entering the water, and the water outlet position of the wastewater tank 2 After the original bottom is raised, the circulating water pump 3 tries to avoid bringing small glass chips into the pipeline when absorbing water. However, a small amount of glass chips will flow toward the water outlet of the waste water tank 2 due to the suction force of the circulating water pump 3 before they have time to sink to the bottom. At this time, these glass chips that have not sunk to the bottom will be directly sucked into the filter element 8 at the water outlet of the waste water tank 2 for filtration. The filtered glass chip water will enter the subsequent two-stage filter for multiple filtrations. This will not cause damage to the inside of the filter, but can also filter out the glass chips in the glass chip water, so that the filtered water without glass chips can be recycled.
[0014] The use process of the present invention is as follows: When in use, first connect the water inlet pipe 6 on the bottle washing device 1 to the clean water valve, so as to supply a large amount of clean water required in the bottle washing device 1. After the bottle washing device 1 completes the process of rinsing the bottles, a large amount of waste water of glass debris formed after rinsing is discharged into the waste water tank 2. When the waste water of glass debris enters the waste water tank 2, it will directly flow through the filter screen 7 covered at the water inlet of the waste water tank 2 for primary filtration, and some large particles of glass debris will be filtered out. A large amount of small glass debris will also exist in the filtered glass debris waste water, and these small glass debris will directly sink to the bottom of the waste water tank 2 after entering the water, and the water outlet of the waste water tank 2 is located at the bottom of the waste water tank 2. After the bottom of the device is raised, the circulating water pump 3 can avoid bringing small glass chips into the pipeline when absorbing water. However, a small amount of glass chips will flow toward the water outlet of the waste water tank 2 due to the suction force of the circulating water pump 3 before sinking to the bottom. At this time, these glass chips that have not sunk to the bottom will be directly sucked into the filter element 8 at the water outlet of the waste water tank 2 for filtration. The filtered glass chip water will then be finely filtered through the first filter 4 and the second filter 5 respectively until all the glass chips and other particles in the glass chip water are filtered out. The filtered water will then enter the bottle washing device 1 through the pipeline for recycling.
[0015] Other unexplained parts of the present invention are the same as those of the prior art.
