Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wastewater treatment, and particularly relates to a deodorization type water treatment equipment for slaughterhouses. BACKGROUND

[0002] In the process of processing livestock, a slaughterhouse will produce a large amount of wastewater containing blood dirt, oil, meat and viscera, and the organic matter in the wastewater will decompose to produce ammonia, hydrogen sulfide and other foul-smelling gases, which will directly pollute the air, so the wastewater needs to be treated before being discharged.

[0003] At present, the wastewater treatment of slaughterhouses mostly uses a shallow air floatation machine, and the main structure thereof includes a pretreatment system, an air floatation tank, a dissolved air system, a water and air distribution system, and a slag scraping and sludge discharge system. In the operation process of the slag scraping and sludge discharge system, the impurities floating on the surface of the wastewater are collected and transported to the middle sludge recovery bin through the sludge discharge pipeline. Since the wastewater of the slaughterhouse contains oil, the oil in the wastewater has strong adhesion. The existing slag scraping and sludge discharge system mainly relies on the rotating skimmer bucket to salvage the impurities. However, the impurities are gradually accumulated on the surface of the skimmer bucket, and the more impurities are adhered to the surface of the skimmer bucket with the extension of the treatment time. After the skimmer bucket is in long-term contact with the adhered impurities containing sulfur and ammonia, chemical corrosion is prone to occur. Meanwhile, the oil solidifies at low temperature to form a gel-like substance mixed with the meat, which will cause the blockage of the sludge discharge pipeline, so that the impurities salvaged by the scraper cannot enter the middle sludge recovery shell, and thus the efficiency of the wastewater treatment is low.

DETAILED DESCRIPTION

[0022] Reference herein to an embodiment means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. As will be apparent to those of ordinary skill in the art, embodiments described herein can be combinable with other embodiments.

[0023] Embodiment 1 The embodiment discloses a deodorizing water treatment equipment for slaughterhouses, and aims at an existing shallow air flotation machine. The deodorizing water treatment equipment mainly comprises a pretreatment module, a solid-liquid separation system, a dissolved gas circulation system and a pipeline flocculation system. The following scheme mainly shows the solid-liquid separation system.

[0024] As Figures 1-7As shown, it includes a support platform 1, a collecting shell 2 is fixedly connected to the support platform 1, a processing shell 3 is fixedly connected to the collecting shell 2, an aeration module for injecting air into the processing shell 3 is provided inside the processing shell 3, and the processing shell 3 is provided with a processing chamber 301 and a transition chamber 302. The processing chamber 301 is used to hold wastewater to be treated, and the processing chamber 301 is connected to the transition chamber 302 through a connecting pipe. The treated wastewater flows into the transition chamber 302 through the connecting pipe. A drain pipe for discharging the treated wastewater in the transition chamber 302 to the outside is provided on the lower side of the processing shell 3. The processing shell 3 is fixed with a central axis 4, and the central axis 4 is provided with a fixed disk 5. A driving module for driving the fixed disk 5 is provided on the central axis 4. The driving module consists of a driving motor, a gear ring, a gear and a mounting shell, wherein the driving motor and the mounting shell are both It is fixed on the central axis 4, and the fixed disk 5 is rotatably connected to the mounting shell. The gear ring and the gear are both located in the mounting shell. The fixed disk 5 is fixed to the gear ring, and the gear is fixed to the output shaft of the drive motor. The fixed disk 5 is provided with a scraping mechanism and an intercepting mechanism. The wastewater mixed with the flocculant is injected into the treatment chamber 301 of the treatment shell 3, and the water level is lower than the upper side of the treatment shell 3, and the wastewater in the treatment chamber 301 is injected with gas through the aeration module. Bubbles are formed in the wastewater, and the bubbles carry impurities in the wastewater and float upward until they move to the wastewater liquid surface. The driving module on the central axis 4 is turned on, the driving module works and drives the fixed disk 5 to start rotating, and the fixed disk 5 drives the scraping mechanism thereon to work, and the scraping mechanism gradually pushes the impurities floating on the liquid surface outward until the impurities enter the collection shell 2.

[0025] The specific structure and connection relationship of each component are as follows: like Figures 1-7 As shown, the scraping mechanism includes: a first driving cylinder 6, which has several spirally distributed ones, all of which are slidably connected to the fixed plate 5, and all the first driving cylinders 6 are equidistantly distributed. The first driving cylinder 6 is slidably connected to the first connecting rod 7, and the lower side of the first connecting rod 7 is fixed with the first plate 8; a gap is left between two adjacent first plates 8, a second plate 9 is slidably connected to the fixed plate 5, and the second plate 9 is located on the inner side of all the first plates 8. The fixed plate 5 is slidably connected to the third plate 10, and the third plate 10 is located on the outer side of all the first plates 8. The second plate 9 and the third plate 10 both rely on the fixed rod to slide up and down along the fixed plate 5, and all the first plates 8 , the second plate 9 and the third plate 10 together form a "spiral plate", the upper side of the first plate 8 is higher than the upper side of the processing shell 3, and there is a gap between the lower side of the first plate 8, the lower side of the second plate 9 and the lower side of the third plate 10 and the lower side wall of the processing shell 3, and the first plate 8, the second plate 9 and the third plate 10 are all higher than the connection between the processing chamber 301 and the transition chamber 302; the rotating frame 31 is rotatably connected to the central axis 4; the fixed ring 32 is arranged on the rotating frame 31, the first connecting rod 7 is rotatably connected to the fixed ring 32, the fixed ring 32 is located below the fixed disk 5, and the second plate 9 and the third plate 10 are both fixed to the fixed ring 32.

[0026] The above settings can achieve: The wastewater mixed with flocculants is injected into the treatment cavity 301 of the treatment shell 3, so that the water surface is lower than the upper side of the treatment shell 3 and is located in the middle of the first plate 8. After the fixed disc 5 starts to rotate, the fixed disc 5 drives all the first plates 8 to rotate counterclockwise (in the perspective of the top view) through all the first driving cylinders 6 and all the first connecting rods 7 on the fixed disc 5. At the same time, the fixed disc 5 drives the second plate 9 and the third plate 10 to rotate synchronously. That is, the "spiral plate" formed by all the first plates 8, the second plate 9 and the third plate 10 starts to rotate. In the process of counterclockwise rotation of the "spiral plate", the "spiral plate" gradually pushes the impurities floating on the liquid surface outwards from the inside of the treatment cavity 301. That is, the impurities gradually move outwards along the "spiral plate". With the rotation of the "spiral plate", the impurities flow into the collection shell 2, and thus the cleaning of the impurities is completed.

[0027] As shown in Figures 1-11 , the intercepting mechanism includes a first scraping net 11, a second scraping net 12 and a third scraping net 13, a driving assembly and a conversion assembly.

[0028] 1, the first scraping net 11, the second scraping net 12 and the third scraping net 13 As shown in Figure 6 , Figure 8 and Figure 10 , the above three are filter screens woven by steel wire ropes (the filter holes of the filter screens are parallelograms, which are not shown in the specific filter structure diagram). The two sides of the first scraping net 11 are respectively fixedly connected with the side edges of the adjacent two first plates 8, and the fixed connection positions of the first scraping net 11 and the adjacent two first plates 8 are located on the sides away from each other (as shown in Figure 10 ). The two sides of the first scraping net 11 are respectively located on different side surfaces of the adjacent first plates 8, that is, the first scraping net 11 is divided into two parts, one part contacts the outer side of one side adjacent first plate 8, and the other part contacts the inner side of the other side adjacent first plate 8 (as shown in Figure 10 ). The second scraping net 12 is attached to the second plate 9 and is fixedly connected with the side edges of the adjacent first plates 8. The second plate 9 is composed of four arc-shaped plates and three square frames arranged at intervals, and the three square frames are used for scraping and cleaning the second scraping net 12. The third scraping net 13 is slidingly connected with the third plate 10 and is fixedly connected with the side edges of the adjacent first plates 8. Initially, all the first scraping nets 11 respectively contact the adjacent first plates 8, the second scraping net 12 contacts the adjacent first plates 8 and the second plate 9, and the third scraping net 13 contacts the adjacent first plates 8 and the third plate 10. After being stretched by the tension, the first scraping net 11, the second scraping net 12 and the third scraping net 13 are deformed. In the deformation process of the above three, the first scraping net 11, the second scraping net 12 and the third scraping net 13 are always attached to all the first plates 8, the second plate 9 and the third plate 10 and slide along the first plates 8, the second plate 9 and the third plate 10.

[0029] The above arrangement can achieve: In the process of treating wastewater, the first scraping net 11, the second scraping net 12 and the third scraping net 13 protect all the first plate 8, the second plate 9 and the third plate 10, reduce the probability of contact between the viscous impurities in the wastewater and them, and reduce the amount of impurities adhered to the first plate 8, the second plate 9 and the third plate 10. In the process of deformation of the first scraping net 11, the second scraping net 12 and the third scraping net 13, the impurities adhered to the first plate 8, the second plate 9 and the third plate 10 are scraped off.

[0030] 2, conversion assembly As shown in Figure 6 , Figure 8 and Figure 12 , the conversion assembly is arranged on the fixed disc 5 and is used for adjusting the second scraping net 12 and the third scraping net 13. The conversion assembly comprises: two second driving cylinders 14, which are both fixed to the fixed disc 5. The two second driving cylinders 14 are respectively located at the innermost side and the outermost side of the “spiral plate”. A second connecting rod 15 is slidably connected to the second driving cylinder 14. The second connecting rod 15 is rotatably connected with the fixed ring 32. Two scraping net rolls 16 are arranged on adjacent second connecting rods 15. The scraping net roll 16 is wound with a filter screen consistent with the structure of the third scraping net 13. The second connecting rod 15 is provided with a protective shell (as shown in Figure 6 and Figure 8 ) wrapping the scraping net roll 16. The filter screens on the two scraping net rolls 16 are fixed to the second scraping net 12 and the third scraping net 13 respectively.

[0031] The above arrangement can achieve: In the process of rotating the second connecting rod 15, the second connecting rod 15 drives the scraping net roll 16 to rotate, so that the scraping net roll 16 releases the filter screen wound thereon or winds the second scraping net 12 and the third scraping net 13. In this way, the second scraping net 12 and the third scraping net 13 are relatively slid with the second plate 9 and the third plate 10 respectively, so as to realize the effect of cleaning the impurities adhered to the second plate 9 and the third plate 10.

[0032] 3, driving assembly As shown in Figure 2 , Figure 4 , Figure 5 and Figure 10 , the driving assembly is arranged on the fixed disc 5 and is used for driving all the first plates 8 to rotate, so that the adjacent first scraping nets 11 are deformed. The driving assembly comprises: a first push rod 21 installed on the fixed disc 5. The first push rod 21 is an existing electric structure, and the internal structure is not described in detail. A support plate 22 is fixed to the telescopic end of the first push rod 21. The support plate 22 is in a spiral shape (as shown in Figure 2), the first driving cylinder 6 and the second driving cylinder 14 are fixedly connected with the support plate 22, the first connecting rod 7 and the second connecting rod 15 are fixedly connected with the convex ball 23 (as shown in Figure 10 ), the first driving cylinder 6 and the second driving cylinder 14 are fixedly connected with the support plate 22, the first connecting rod 7 and the second connecting rod 15 are fixedly connected with the convex ball 23 (as shown in

[0033] The above settings can achieve: In the process of moving upward of the first driving cylinder 6 and the second driving cylinder 14, the first driving cylinder 6 drives the first connecting rod 7 to rotate, and at the same time, the second driving cylinder 14 drives the second connecting rod 15 to rotate, the first connecting rod 7 and the second connecting rod 15 drive the adjacent first plate 8 and the adjacent scraping net roll 16 to rotate respectively, in the process of rotating of the first plate 8, the first plate 8 pulls and stretches the adjacent first scraping net 11, so that the first scraping net 11 is deformed, and at the same time, the contact position of a part of the first scraping net 11 with the adjacent first plate 8 is changed, the contact position of another part of the first scraping net 11 with the first plate 8 on the other side is changed, so that the contact mode of the first scraping net 11 with the waste water is changed, and the first scraping net 11 scrapes the impurities on the surface of the first plate 8.

[0034] The working process of the deodorizing water treatment equipment in the embodiment is as follows: Preparation for treatment: First, the waste water is pumped into the pretreatment system, and the large impurities in the waste water are filtered through the pretreatment, and then the waste water passes through the pipeline flocculation system, and an appropriate amount of flocculant is added to the waste water flowing through, so that the waste water generates flocculation impurities under the action of the flocculant and floats in the waste water, and then the waste water is injected into the treatment cavity 301 of the treatment shell 3, and the solid-liquid separation work of the waste water is started, and at the same time, the gas-containing clear water is injected into the waste water through the dissolved air system, the injected clear water is mixed in the waste water, at the same time, the bubbles in the clear water are dispersed into small bubbles, and enter the waste water, at this time, the small bubbles carry the flocculation impurities and oil stains (hereinafter referred to as impurities) in the waste water to float upwards, until the impurities float on the surface of the waste water.

[0035] Start treatment: The driving module on the central shaft 4 starts to work and drives the fixed disc 5 to rotate counterclockwise, and the "spiral plate" formed by all the first plates 8, the second plates 9 and the third plates 10 starts to rotate. During this process, all the first plates 8, the second plates 9 and the third plates 10 (the three are referred to as spiral plates) drive all the first cleaning nets 11, the second cleaning nets 12 and the third cleaning nets 13 (the three are referred to as cleaning nets) to rotate synchronously. The spiral plates and the cleaning nets jointly guide the impurities, so that the impurities gradually move outward and gradually accumulate above the wastewater surface. When the impurities exceed the upper side of the treatment shell 3, the impurities enter the collection shell 2. During this process, the treated wastewater enters the transition cavity 302 and is discharged to the outside. At the same time, the operator collects the discharged clean water.

[0036] The spiral plate pushes the impurities, constantly changes the position of the impurities, and reduces the contact dead angle with the impurities by using the smooth curve of the spiral plate, so as to facilitate the movement of the impurities and reduce the accumulation of the impurities on the spiral plate, thereby facilitating the subsequent cleaning operation.

[0037] During the rotation of the cleaning net, the cleaning net blocks the impurities, reduces the probability of the impurities adhering to the spiral plate, thereby reducing the amount of impurities adhering to the spiral plate and ensuring the normal use of the spiral plate.

[0038] During the operation of the driving module on the central shaft 4, the first push rod 21 is opened at regular intervals. The telescopic end of the first push rod 21 first drives the support plate 22 to move downward by a fixed distance (the moving distance is set by the program), and the support plate 22 drives all the first driving cylinders 6 and the second driving cylinders 14 on it to move downward.

[0039] During the downward movement of the first driving cylinder 6, two first driving cylinders 6 in the Figure 10 are taken as examples for description. The first driving cylinder 6 extrudes the adjacent convex ball 23 through the limiting groove 24, so that the convex ball 23 slides along the adjacent limiting groove 24. During this process, the left first connecting rod 7 starts to rotate counterclockwise under the action of the adjacent convex ball 23, the left first connecting rod 7 drives the adjacent first plate 8 to rotate counterclockwise, and the right first connecting rod 7 starts to rotate clockwise under the action of the adjacent convex ball 23, and the right first connecting rod 7 drives the adjacent first plate 8 to rotate clockwise.

[0040] In the process of rotating the two first plates 8, the left first plate 8 drives the left edge of the rear first scraper 11 to move forward, and the right first plate 8 drives the right edge of the front first scraper 11 to move forward. In this process, the left and right parts of the first scraper 11 are still attached to the left and right first plates 8 respectively, and the left and right parts of the first scraper 11 are stretched and deformed under the tension, thereby changing the contact position of the first scraper 11 with the corresponding two first plates 8, so that the first scraper 11 scrapes the impurities on the corresponding two first plates 8 (the rear side of the left first plate 8 and the front side of the right first plate 8). Through the swing of the two first plates 8, the shape of the first scraper 11 changes, so that the impurities attached to the first scraper 11 are loosened, facilitating the falling of the impurities thereon.

[0041] After the telescopic end of the first push rod 21 stops extending, the two first plates 8 stop rotating, at this time, the two first plates 8 form a structure similar to a positive "eight" character, that is, the gap between the two first plates 8 increases, facilitating the wastewater to pass through the gap therebetween. In the process of wastewater passing through the gap, the wastewater impacts the first scraper 11, and through the impact of the wastewater, the impurities on the first scraper 11 are further treated, so that the impurities thereon are separated.

[0042] In the process of moving the second drive cylinder 14 downward, Figure 9 for example, when the second drive cylinder 14 moves downward, the adjacent second connecting rod 15 is driven to rotate clockwise by the limiting groove 24 and the convex ball 23 thereon, the second connecting rod 15 drives the scraper roll 16 to rotate and releases the filter screen thereon. At this time, the first plate 8 close to the third plate 10 rotates counterclockwise and pulls the third scraper 13, so that the contact position of the third scraper 13 with the third plate 10 changes, and the third scraper 13 cleans the impurities on the third plate 10. In this process, after the first plate 8 close to the third plate 10 rotates, a gap is formed between the first plate 8 and the third plate 10, so that the wastewater can pass through the gap therebetween and impact the third scraper 13, facilitating the cleaning of the impurities of the third scraper 13.

[0043] With the working of the drive module on the central shaft 4, the telescopic end of the first push rod 21 is withdrawn in time and reversely repeats the above steps, so that the spiral plate and the cleaning screen return to the initial state.

[0044] The above process describes the process of the telescopic end of the first push rod 21 moving downward and resetting. After the telescopic end of the first push rod 21 is withdrawn, the first push rod 21 is opened again in time. This time, the telescopic end of the first push rod 21 drives the support plate 22 to move upward, at this time, Figure 10Two first plates 8 in the middle are taken as an example, the first plate 8 on the left rotates clockwise, and the first plate 8 on the right rotates counterclockwise, so that the two first plates 8 form an approximate inverted "8" structure after rotating, and meanwhile, the left and right parts of the first scraping net 11 still respectively adhere to the adjacent first plates 8, the contact positions of the left and right parts of the first scraping net 11 with the corresponding first plates 8 are changed, so that the impurities on the corresponding two first plates 8 are scraped, and the position of the first scraping net 11 impacted by the water flow is changed, thereby further improving the cleaning effect of the first scraping net 11. During the repositioning of the extension end of the first push rod 21, the first plate 8 on the left rotates counterclockwise, and the first plate 8 on the right rotates clockwise.

[0045] When the extension end of the first push rod 21 drives the support plate 22 to move upward, the second drive cylinder 14 drives the scraping net roll 16 to rotate through the second connecting rod 15 and winds the filter screen thereon, so that the contact position of the third scraping net 13 with the third plate 10 is changed again, and the third scraping net 13 cleans the impurities on the third plate 10, thereby ensuring the cleanliness of the third plate 10. During this process, the working process of the scraping net roll 16 close to the second plate 9 is also the same.

[0046] During the working process of the drive module on the middle shaft 4, the first push rod 21 reciprocates regularly, and the working mode is that the extension end of the first push rod 21 first moves downward and then repositions, and then moves upward and then repositions, and the process is repeated, so that the spiral plate and the cleaning net are cleaned synchronously, thereby reducing the adhesion of impurities on the spiral plate and the cleaning net and reducing the damage of the impurities to the spiral plate and the cleaning net.

[0047] After the wastewater treatment is completed, the operator closes the drive module on the middle shaft 4 and closes the remaining electrical elements, and at the same time, after all the wastewater is discharged, clean water is injected into the treatment cavity 301 of the treatment shell 3, so as to flush the treatment cavity 301 of the treatment shell 3.

[0048] Embodiment 2 The embodiment discloses a deodorizing water treatment equipment for slaughterhouses, which further has the function of further cleaning the cleaning net on the basis of the embodiment 1.

[0049] As shown in Figures 1-6 , Figure 10 and Figure 11 , a plurality of scraping plates 33 are rotationally connected to the fixed ring 32, the scraping plates 33 are used to clean the first scraping net 11, the second scraping net 12 and the third scraping net 13, all the scraping plates 33 are respectively located between adjacent two first plates 8, between the third plate 10 and the adjacent first plate 8, and between the second plate 9 and the adjacent first plate 8, and all the scraping plates 33 respectively adhere to the adjacent first scraping net 11, second scraping net 12 and third scraping net 13; the inside of the scraping plate 33 is provided with a strip-shaped protrusion (as shown in Figure 11The strip-shaped protrusions are used to increase the contact area between the scraper 33 and the cleaning net.

[0050] The above arrangement can achieve: In the working process of the first push rod 21, the working content of the above-mentioned embodiment 1 is repeated.
