Description

Technical Field

[0001] The invention relates to a stone processing technology, and in particular to a granite stone processing sewage treatment device. Background Art

[0002] Granite processing is an important basic industry in the fields of building decoration, municipal engineering, etc. Its production process covers key processes such as cutting, grinding, and polishing. In the process of processing, in order to reduce equipment loss and control dust pollution, a large amount of cooling water is required for wet operations. The wastewater generated contains high concentrations of suspended solids (the main components are quartz sand, feldspar powder and other stone powder particles with a particle size of 0.1-100μm), chemical oxygen demand (COD) and oil pollutants. According to statistics, about 5-8 tons of wastewater are generated for every cubic meter of granite slab processed. If it is directly discharged without effective treatment, it will lead to environmental problems such as increased water turbidity, damage to the ecosystem and pipe blockage.

[0003] When treating the wastewater generated by granite stone processing, the colloidal dirt generated after flocculation cannot be cleaned in real time, and filtering and separation operations need to be performed after the flocculation is completed. Therefore, multiple flocculation tanks need to be set up as backup. When one flocculation tank is cleaning the dirt, the backup flocculation tank needs to be used for flocculation again.

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0032] Example 1

[0033] like Figure 1-4 As shown, a granite stone processing wastewater treatment device comprises: a pretreatment tank 1, a reaction tank 2;

[0034] A floating plate 12 is provided in the pretreatment tank 1, and an isolation fence 13 is installed on the floating plate 12. A liquid inlet 14 is provided on one side of the pretreatment tank 1, and a liquid outlet 15 is provided on the other side. The isolation fence 13 is located between the liquid inlet 14 and the liquid outlet 15. Two isolation plates 21 are provided inside the reaction tank 2. The two isolation plates 21 divide the reaction tank 2 into three chambers. The upper layer is a sedimentation chamber 101, the middle layer is a liquid injection chamber 102, and the lower layer is a circulation chamber 103. The liquid injection chamber 102 is connected to the liquid outlet 15 on the pretreatment tank 1 through a conveying pipeline. A water pump is arranged on the conveying pipeline to convey sewage. A dosing port 22 is provided on the side of the liquid injection chamber 102. The liquid injection chamber 102 is connected to the upper part of the reaction tank 2 through a conveying pipeline. A water outlet 23 is provided on the side of the sedimentation chamber 101. A sedimentation column 24 is provided on the isolation plate 21 at the bottom of the sedimentation chamber 101. The sedimentation column 24 passes through the liquid injection chamber 102 to connect the sedimentation chamber 101 with the circulation chamber 103.

[0035] A circulation cylinder 31 is rotatably installed in the circulation chamber 103, and circulation ports 32 are arranged in a matrix at equal angles on the side wall of the circulation cylinder 31. A scraper 33 is installed on the circulation port 32, and a 45-degree angle is formed between the scraper 33 and the tangent of the outer circle of the circulation cylinder 31. A filter segment 34 is arranged on the side wall of the circulation cylinder 31 between two adjacent scrapers 33. The filter segment 34 and the circulation port 32 are respectively located on both sides of the scraper 33. The circulation port 32 is located on one side of the angle between the scraper 33 and the tangent of the circulation cylinder 31. A guide cylinder 35 is connected to the upper part of the circulation cylinder 31, and a separation plate A support cylinder 36 is fixedly installed on 21, and a guide cylinder 35 is coaxially arranged inside the support cylinder 36. The support cylinder 36 and the guide cylinder 35 form a connection chamber with a sealed upper end and a lower end connected to the circulation chamber 103. A filter screen 37 is provided on the side wall of the guide cylinder 35 in the connection chamber. A lifting screw 38 is rotatably installed inside the guide cylinder 35. The lower end of the lifting screw 38 is connected to the output shaft of a driving motor 39. The driving motor 39 is installed at the bottom of the reaction tank 2. The output shaft of the driving motor 39 drives the circulation cylinder 31 to rotate through a gear mechanism.

[0036] Sewage is injected into the injection chamber 102, and flocculant is injected from the dosing port 22 at the same time. The sewage and flocculant are mixed in the injection chamber 102. The mixed sewage is transported to the upper part of the reaction tank 2 by the water pump, and enters the sedimentation chamber 101 from the upper part of the reaction tank 2. It is precipitated in the sedimentation chamber 101. The colloidal dirt generated during the flocculation process settles in the sedimentation column at the bottom of the sedimentation chamber 101 under the action of gravity, and enters the circulation chamber 103 from the sedimentation column. The driving motor 39 in the circulation chamber 103 drives the lifting screw 38 to rotate together with the circulation cylinder 31. When the circulation cylinder 31 rotates, the scraper 33 on its outer ring pushes the liquid flow outside the circulation cylinder 31 into the inside of the circulation cylinder 31, and then flows out of the circulation cylinder 31 through the filter segment 34 on the circulation cylinder 31. The filter segment 34 will enter the circulation The colloidal dirt in the sewage in the cylinder 31 is filtered into the circulation cylinder 31, and then lifted upward by the lifting screw 38. During the lifting process, when the water in the colloidal dirt passes through the filter screen 37 on the side wall of the guide cylinder 35, the water in the colloidal dirt can pass through the filter screen 37 and flow downward along the chamber between the guide cylinder 35 and the support cylinder 36, and the colloidal dirt is discharged from the upper end of the guide cylinder 35 under the lifting of the lifting screw 38; the dirt produced by the precipitation is filtered and separated once through the filter screen section 34 on the circulation cylinder 31, and the separated colloidal dirt is then lifted to the filter screen 37 by the lifting screw 38, and then the colloidal dirt is filtered and separated twice by the filter screen 37, so that the colloidal dirt produced by flocculation can be cleaned in real time, the accumulation of colloidal dirt is avoided, and the flocculation efficiency is improved;

[0037] Sewage is injected into the pretreatment tank 1 from the liquid inlet 14, and the scum in the sewage is primarily filtered by the isolation fence 13 on the floating plate 12 in the pretreatment tank 1 to reduce floating objects in the water. The sewage after the primary filtration is transported to the injection chamber 102 through the delivery pipe through the liquid outlet 15, and reacts with the flocculant in the injection chamber 102. The mixed liquid after the reaction is transported to the sedimentation chamber 101 through the pipeline for sedimentation. The colloidal dirt formed by the sedimentation sinks to the circulation chamber 103 along the sedimentation column 24 under the action of gravity, and the colloidal dirt in the water is separated by the circulation cylinder 31 in the circulation chamber 103. The separated colloidal dirt is lifted by the lifting screw 38 to the upper end of the guide cylinder 35 and discharged. The sewage is treated in multiple stages by flocculation-sedimentation-filtration, and the scum in the sewage is cleaned by pretreatment before flocculation to reduce the influence of the scum on the flocculation operation.

[0040] The circulating drum 31 rotates to filter the sewage, and the filtered colloidal dirt is retained in the circulating drum 31, and is accumulated at the funnel-shaped structure under the guidance of the guide plate 43 and the filter screen segment 34. The friction wheel 45 is driven to move by the rotation of the circulating drum 31, and the friction wheel 45 contacts the bottom of the reaction tank 2, thereby causing the friction wheel 45 to rotate. The rotation of the friction wheel 45 drives the feeding screw 44 to rotate. The feeding screw 44 rotates to promote the colloidal dirt at the funnel-shaped structure to move into the inner drum 41 under the push of the feeding screw 44.

[0041] The filter segment 34 is in a semicircular arc structure. A cleaning shaft 51 is rotatably mounted on the circulation drum 31.

The isolation filter 64 is provided on the floating ring 63 to prevent the dirt in the sedimentation chamber 101 from flowing out of the water outlet 23, and the water discharged from the water outlet 23 is filtered.

[0043] The sewage transported from the injection chamber 102 to the reaction tank 2 is filtered once through the filter screen 37 to separate the floating dirt in the water. Furthermore, the colloidal dirt lifted by the lifting screw 38 will also fall from the upper part of the guide cylinder 35 to the filter screen plate 61, so as to facilitate the collection of the dirt.

[0044] An impeller 65 is installed on the material guide cylinder 35, and the impeller 65 is located in the chamber formed between the material guide cylinder 35 and the support cylinder 36; the impeller 65 generates suction to promote water to flow from the filter screen 37 to the chamber between the support cylinder 36 and the material guide cylinder 35, thereby reducing the water content of the dirt discharged by the material guide cylinder 35, and the water passing through the filter screen 37 flows back to the circulation chamber 103, which can maintain the water balance in the circulation chamber 103 and reduce the water flow in the sedimentation chamber 101 and the circulation chamber 103.

The driven ring 82 is rotated to drive the paddle 86 to move. When the paddle 86 moves, it is elastically fluctuated by the angular fluctuation of the square structure of the outer section of the sedimentation column 24. Under the influence of the paddle 86, the sedimentation column 24 vibrates, and the vibration of the sedimentation column 24 is used to promote the colloidal dirt inside the sedimentation column 24 to settle downward.

The main gear 92 is installed on the lifting screw 38, and the secondary shaft 93 is rotatably installed on the reaction tank 2. The secondary gear 94 is installed on the secondary shaft 93.
