Description

Technical Field

[0001] The utility model relates to the technical field of slaughterhouse sewage treatment, in particular to a solid waste interception device. Background Art

[0002] The sewage pre-treatment stage usually allows the sewage to flow through the coarse screen and fine screen in the screen pool. The coarse screen is used to intercept large-sized suspended solids and floating objects and other solid wastes, protect the fine screen from being damaged by large particles, and also reduce the load of the fine screen; the fine screen is used to intercept smaller particles that the coarse screen fails to intercept, such as fibers, hair, food residues, etc., and further protect subsequent treatment equipment, reduce the demand for small particles in the subsequent treatment process, and reduce the use of chemicals and sludge production.

[0003] However, there are impurities such as animal tissue residues and bone residues in the slaughterhouse wastewater. The animal tissue residues have high adhesion, irregular shape and are easy to deform, while the bone residues are hard and irregular in size. When filtering in the screen pool, impurities such as minced meat and bone residues are easy to adhere to or get stuck on the rake teeth, and the mesh is also easy to be blocked. In serious cases, the mesh needs to be replaced. Using a screen with a larger gap will bring a greater load to the fine screen machine or subsequent processes. Therefore, the coarse screen machine and the fine screen machine need to be inspected and cleaned daily, which is time-consuming and labor-intensive. The workload of repairing and replacing rake teeth is large. Therefore, it is necessary to intercept the solid waste in the slaughterhouse wastewater before it enters the screen pool.

[0004] Chinese Patent No.: ZL202321810870.6 discloses an intercepting device for sewage treatment in a sewage treatment pool, including a sewage treatment tank and a transmission motor, a transmission shaft of the transmission motor passes through the inner wall of the sewage treatment tank, and the other end of the transmission shaft of the transmission motor is fixedly connected to a driving gear, and the two sides of the driving gear are respectively meshed with a driven gear one and a driven gear two, and a first sector gear is concentrically connected to the driven gear one, one side of the first sector gear is meshed with a transmission rack, and the other side of the transmission rack is meshed with a second sector gear, and the driving gear is driven by the transmission motor to rotate, the driving gear drives the driven gear to rotate, the driven gear drives the sector gear to rotate, and the sector gear drives the transmission rack to move up and down, so that the intercepting plate drives the large volume of garbage on the surface to move to the cleaning port of the sewage treatment tank, and then the cleaning rod is used to remove the large volume of garbage, so that the garbage on the intercepting plate can be automatically salvaged after filtering, thereby improving the cleaning rate and the overall efficiency of sewage treatment. However, in the process of intercepting slaughterhouse wastewater, the irregularly shaped animal tissue residues are easily hung on the interception plate or the transmission rack, affecting the interception effect of subsequent solid waste. Secondly, during use, it is necessary to frequently use a cleaning rod to remove large-volume garbage on the interception plate from the cleaning port, and the cleaning process is time-consuming and labor-intensive. Finally, due to the irregular shapes of solid waste in the slaughterhouse wastewater, some long animal tissue residues or bone residues are easy to pass through the interception plate and be discharged from the drain pipe, resulting in low interception efficiency, which brings a large load to the screen machine or subsequent processes. Summary of the invention

[0005] The technical problems to be solved by the utility model are how to improve the interception efficiency of solid waste in slaughterhouse wastewater, how to facilitate the discharge of solid waste and how to improve the interception efficiency of solid waste. The purpose of the utility model is to provide a solid waste interception device for slaughterhouse wastewater, which utilizes an arc-shaped screen and unequally spaced spiral blades to intercept solid waste in slaughterhouse wastewater and automatically discharge the solid waste.

[0006] The technical solution adopted by the utility model is: a slaughterhouse sewage solid waste interception device, comprising a frame, a top cover is provided on the top of the frame, and the frame and the top cover are detachably connected by bolts; a water inlet is provided at one end of the top cover, the top of the frame is arranged to be inclined upward at the upper side away from the end of the water inlet, and a water collecting bottom plate is provided at the bottom of the frame, and the lower side of the water collecting bottom plate is arranged to be inclined downward away from the end of the water inlet; an arc-shaped screen and a spiral shaft are installed in the frame, and the spiral shaft is arranged on the upper surface of the arc-shaped screen; a drain is provided at the end of the water collecting bottom plate away from the water inlet.

[0007] The following beneficial effects can be achieved by using the slaughterhouse sewage solid waste interception device provided by the utility model:

[0008] (1) The slaughterhouse wastewater is filtered through an arc-shaped screen, and the animal tissue residues and bone residues and other solid wastes blocked by the arc-shaped screen are pushed and discharged along the arc-shaped screen by the spiral shaft, so that the slaughterhouse wastewater without large particles of solid waste after filtration is discharged from the drain outlet along the water collection bottom plate, thereby reducing the load for subsequent filtration of the screen pool and subsequent treatment processes, preventing minced meat from adhering to the rake teeth, preventing bone residues from getting stuck on the rake teeth, and also preventing minced meat, bone residues, etc. from clogging the screen machine grid.

[0009] (2) The arc-shaped screen and the spiral shaft can automatically scrape off the solid waste such as minced meat and bone residue on the surface of the arc-shaped screen, effectively preventing the arc-shaped screen from being blocked. There is no need to check and clean it every day, and the cleaning and maintenance are easy, saving time and effort.

[0010] (3) After the slaughterhouse wastewater containing solid waste enters the rack, the solid impurities are discharged upward along the arc-shaped screen. Under the action of gravity, the intercepted and filtered wastewater is discharged downward along the water collecting bottom plate at the bottom of the rack, preventing the intercepted wastewater from mixing with the impurities again, thereby improving the interception efficiency of the slaughterhouse wastewater solid waste interception device and reducing the workload of the screen pool.

[0011] Preferably, mounting grooves are provided on the outer edges on both sides of the top of the frame, mounting plates are provided on the outer edges on both sides of the arc-shaped screen, and the mounting plates on the arc-shaped screen are adapted to the mounting grooves on the top of the frame and are detachably connected by bolts.

[0012] The arc-shaped screen can be easily fixed and installed through the installation groove, and the arc-shaped screen can be detachably connected through bolts to prevent leakage caused by rotation or displacement of the arc-shaped screen during the process of intercepting solid waste.

[0013] Preferably, a teardrop-shaped filter hole is provided on the side of the arc-shaped screen close to the water inlet, a circular filter hole is provided on the side close to the drain outlet, and a strip filter hole is provided between the teardrop-shaped filter hole and the circular filter hole. The maximum width of the teardrop-shaped filter hole is greater than the width of the strip filter hole, and the width of the strip filter hole is greater than the width of the circular filter hole.

[0014] The slaughter wastewater containing impurities is filtered in sequence after entering the frame through the drop-shaped filter holes, strip filter holes and circular filter holes arranged in sequence on the arc-shaped screen. The water flow rate is large at the end close to the water inlet, and the drop-shaped filter holes with large width can prevent blockage caused by the sewage flushing process; the end away from the water inlet does not affect the drainage effect and can reduce the water content of the solid waste.

[0015] Preferably, the ends of the teardrop-shaped filter holes with larger width are close to one side of the drain outlet.

[0016] By placing the wider end of the teardrop-shaped filter hole close to the drain outlet, solid waste can be prevented from falling into the teardrop-shaped filter hole and getting stuck in the hole when moving on the surface of the arc-shaped screen, without affecting the passage of solid waste with smaller volume and more regular shape, thereby reducing the frequency of cleaning and maintenance.

[0017] Preferably, the spiral shaft is provided with unequally spaced spiral blades, and the outer edges of the unequally spaced spiral blades are in contact with the upper surface of the arc-shaped screen.

[0018] By making the edges of the unequally spaced spiral blades fit against the upper surface of the arc-shaped screen, the efficiency of intercepting solid waste can be improved, preventing solid waste from passing through the gap between the unequally spaced spiral blades and the arc-shaped screen. At the same time, the solid waste is scraped and moved under the action of the rotation of the unequally spaced spiral blades, thereby ensuring the interception effect of solid waste.

[0019] Preferably, the edges of the unequally spaced spiral blades are provided with cutting edges facing the drainage outlet.

[0020] By setting a knife edge on the edge of the unequally spaced spiral blades, after a part of the irregular solid waste falls under the arc-shaped screen, it can be cut off by the shearing action of the knife edge and the upper surface of the arc-shaped screen, thereby preventing the filter holes from being blocked or the solid waste from accumulating and causing damage to the unequally spaced spiral blades.

[0021] Preferably, the end with a wider pitch on the unequal-pitch spiral blade is close to the water inlet, and the end with a narrower pitch is close to the drain outlet.

[0022] The end with a wider pitch of the unequal-pitch spiral blades does not affect the flow of slaughterhouse wastewater containing solid waste. The end with a narrower pitch of the unequal-pitch spiral blades causes the solid waste to gradually decrease in the process of being pushed by the unequal-pitch spiral blades, thereby accelerating the discharge of water and making smaller solid wastes approach each other to prevent clogging of the circular filter holes.

[0023] Preferably, the lengths of the two ends of the unequally spaced spiral blades are greater than the lengths of the arc-shaped screen and the top of the frame; the length of the top cover is equal to the lengths of the two ends of the unequally spaced spiral blades.

[0024] The lengths of both ends of the unequally spaced spiral blades are greater than the lengths of the arc-shaped screen and the top of the frame, thereby facilitating the discharge of solid waste along the arc-shaped screen to the outside of the frame for collection; the top cover facilitates shielding the tops of the unequally spaced spiral blades.

[0025] Preferably, the end with a wider pitch of the unequal-pitch spiral blade is aligned with the end of the frame close to the water inlet, and the end with a narrower pitch of the unequal-pitch spiral blade extends out of the frame and is aligned with the end of the top cover close to the drain outlet.

[0026] By making one end of the unequally spaced spiral blades abut against the end of the frame near the water inlet, dead corners that cause solid waste to accumulate during the interception process can be avoided; the other end of the unequally spaced spiral blades extends out of the frame to facilitate the unequally spaced spiral blades to discharge the solid waste out of the frame, preventing the solid waste from accumulating on the arc-shaped screen.

[0027] Preferably, a bottom cover is installed at one end of the top of the frame close to the drain outlet, the top of the bottom cover is detachably connected to the bottom of the top cover by bolts, and a slag discharge port is provided at the bottom of the bottom cover.

[0028] The bottom cover can be used to limit the discharge range of intercepted solid waste, and the slag discharge port can be used to discharge and collect the solid waste at a fixed location.

[0029] Preferably, a reduction motor is fixed to one end of the top cover near the drain outlet, one end of the screw shaft is rotatably connected to the side wall of the frame near the water inlet, and the other end of the screw shaft passes through the bottom cover and is connected to the power output shaft of the reduction motor.

[0030] The two ends of the spiral shaft are limited by the frame and the bottom cover, and the spiral shaft is driven to rotate by the reduction motor, so that the spiral shaft is continuously driven to rotate by the reduction motor, thereby achieving the purpose of continuously intercepting solid waste.

The intercepted and filtered sewage is discharged downward along the water collecting bottom plate 14 at the bottom of the frame 1 under the action of gravity, and the solid waste interception effect is good, which reduces the workload of the grille pool.

[0043] Reference Figure 3 As shown, in this embodiment, the outer edges of both sides of the top of the frame 1 are provided with mounting grooves 11, and the outer edges of both sides of the arc-shaped screen 12 are provided with mounting plates 121. The mounting plates 121 on the arc-shaped screen 12 are adapted to the mounting grooves 11 on the top of the frame 1 and are detachably connected by bolts. The mounting grooves 11 are used to facilitate fixing and installing the arc-shaped screen 12, and the arc-shaped screen 12 is detachably connected by bolts to prevent the arc-shaped screen 12 from rotating or displacing and causing leakage during the interception of solid waste.

[0044] Reference Figure 4 As shown, in the present embodiment, a teardrop-shaped filter hole 122 is provided on the side of the arc-shaped screen 12 close to the water inlet 21, a circular filter hole 124 is provided on the side close to the drain port 15, and a strip filter hole 123 is provided between the teardrop-shaped filter hole 122 and the circular filter hole 124. The maximum width of the teardrop-shaped filter hole 122 is greater than the width of the strip filter hole 123, and the width of the strip filter hole 123 is greater than the width of the circular filter hole 124. The slaughter sewage containing impurities enters the frame 1 and is filtered in sequence through the teardrop-shaped filter holes 122, the strip filter holes 123 and the circular filter holes 124 arranged in sequence on the arc-shaped screen 12. The water flow rate at the end close to the water inlet 21 is large, and the teardrop-shaped filter holes 122 with a large width can prevent blockage caused by the sewage flushing process; the strip filter holes 123 and the circular filter holes 124 at the end away from the water inlet 21 will not affect the drainage effect, and will push the solid waste while reducing its water content.

[0045] Reference Figure 4 As shown, in the present embodiment, the wider end of the teardrop-shaped filter hole 122 is close to one side of the drain port 15, which can prevent solid waste from falling into the teardrop-shaped filter hole 122 and being stuck in the teardrop-shaped filter hole 122 during the movement on the surface of the arc-shaped screen 12, without affecting the passage of solid waste with smaller volume and more regular shape, thereby reducing the frequency of cleaning and maintenance.

[0046] Reference Figure 2 As shown, in this embodiment, unequally spaced spiral blades 131 are provided on the spiral shaft 13, and the outer edges of the unequally spaced spiral blades 131 are in contact with the upper surface of the arc-shaped screen 12. By making the edges of the unequally spaced spiral blades 131 in contact with the upper surface of the arc-shaped screen 12, the efficiency of intercepting solid waste can be improved, and the solid waste can be prevented from passing through the gap between the unequally spaced spiral blades 131 and the arc-shaped screen 12. At the same time, the solid waste can be scraped and moved under the action of the rotation of the unequally spaced spiral blades 131, thereby ensuring the interception effect of the solid waste.

[0047] Reference Figure 5 and Figure 6 As shown, in this embodiment, the edge of the unequally spaced spiral blade 131 is provided with a knife edge 132 facing the drain outlet 15. By providing the knife edge 132 on the edge of the unequally spaced spiral blade 131, after a part of the irregular solid waste falls under the arc-shaped screen 12, it can be cut off by the shearing action of the knife edge 132 and the upper surface of the arc-shaped screen 12, thereby preventing the solid waste from clogging the filter holes or agglomerating, resulting in the inability to discharge the solid waste and causing damage to the unequally spaced spiral blade 131.

[0048] Reference Figure 2 As shown, in this embodiment, the end with a wider pitch on the unequally spaced spiral blade 131 is close to the water inlet 21, and the end with a narrower pitch is close to the drain outlet 15. The end with a wider pitch of the unequally spaced spiral blade 131 does not affect the flow of slaughter wastewater containing solid waste. The end with a narrower pitch of the unequally spaced spiral blade 131 causes the solid waste to gradually decrease in the process of being pushed by the unequally spaced spiral blade 131, thereby accelerating the discharge of water and making smaller solid wastes approach each other to prevent clogging of the circular filter hole 124.

[0049] Reference Figure 2 As shown, in this embodiment, the lengths of the two ends of the unequally spaced spiral blades 131 are greater than the lengths of the arc-shaped screen 12 and the top of the frame 1; the length of the top cover 2 is equal to the lengths of the two ends of the unequally spaced spiral blades 131, and the lengths of the two ends of the unequally spaced spiral blades 131 are greater than the lengths of the arc-shaped screen 12 and the top of the frame 1, thereby facilitating the discharge of solid waste along the arc-shaped screen 12 to the outside of the frame 1 for collection; the top cover 2 facilitates shielding the tops of the unequally spaced spiral blades 131.

[0050] Reference Figure 2 As shown, in the present embodiment, the end with a wider pitch of the unequally spaced spiral blade 131 is aligned with the end of the frame 1 close to the water inlet 21, and the end with a narrower pitch of the unequally spaced spiral blade 131 extends out of the frame 1 and is aligned with the end of the top cover 2 close to the drain outlet 15. By making one end of the unequally spaced spiral blade 131 abut against the end of the frame 1 close to the water inlet 21, dead corners that cause solid waste to accumulate during the interception process are avoided; the other end of the unequally spaced spiral blade 131 extends out of the frame 1 to facilitate the unequally spaced spiral blade 131 to discharge the solid waste out of the frame 1, thereby preventing the solid waste from accumulating on the arc-shaped screen 12.

[0051] Reference Figure 3 As shown, in this embodiment, a bottom cover 3 is installed at one end of the top of the frame 1 close to the drain outlet 15. The top of the bottom cover 3 is detachably connected to the bottom of the top cover 2 by bolts. A slag discharge port 31 is provided at the bottom of the bottom cover 3. The bottom cover 3 is used to limit the discharge range of the intercepted solid waste. The slag discharge port 31 is used to facilitate the discharge of solid waste and the collection of solid waste at a fixed location.

[0052] Reference Figure 1 As shown, in the present embodiment, a reduction motor 22 is fixed to one end of the top cover 2 close to the drain outlet 15, one end of the screw shaft 13 is rotatably connected to the side wall of the frame 1 close to the water inlet 21, and the other end of the screw shaft 13 is connected to the power output shaft of the reduction motor 22 after passing through the bottom cover 3. The two ends of the screw shaft 13 are restricted by the frame 1 and the bottom cover 3, and the screw shaft 13 is driven to rotate by the reduction motor 22, so that the screw shaft 13 is continuously driven to rotate by the reduction motor 22, thereby achieving the purpose of continuously intercepting solid waste.

[0053] Example 2

[0054] When the utility model is used, the reduction motor 22 is started, and the reduction motor 22 drives the spiral shaft 13 to start rotating, and then the slaughter sewage containing animal tissue residues, bone residues and other solid wastes is injected into the frame 1 from the water inlet 21, and the sewage containing grease, blood and small suspended particles passes through the arc-shaped screen 12 and falls onto the water collecting bottom plate 14, and flows along the inclined water collecting bottom plate 14 and is finally discharged from the drain port 15, and the larger animal tissue residues, bone residues and other solid wastes intercepted by the arc-shaped screen 12 are pushed obliquely upward along the surface of the inclined arc-shaped screen 12 by the unequally spaced spiral blades 131 on the spiral shaft 13 under the action of the continuously rotating spiral shaft 13;

[0055] After the sewage containing solid waste enters the frame 1, it first contacts the teardrop-shaped filter hole 122 on the arc-shaped screen 12. The end of the teardrop-shaped filter hole 122 with a larger width is far away from the water inlet 21. The irregularly shaped solid waste is pressed against the edge of the unequally spaced spiral blades 131 during the pushing process of the unequally spaced spiral blades 131, so that the smaller minced meat or bone residue can pass through the teardrop-shaped filter hole 122 and enter the grille pool with the sewage, and be filtered by the grille machine in the grille pool.

[0056] If part of the irregularly shaped animal tissue residue has passed through the teardrop-shaped filter hole 122, the knife edge 132 of the unequally spaced spiral blade 131 facing the drain outlet 15 can use shear force to cut it to a size that can be filtered by the grille machine during the relative movement with the arc-shaped screen 12, while the animal tissue residue larger than the teardrop-shaped filter hole 122 continues to be pushed obliquely upward along the upper surface of the arc-shaped screen 12 under the action of the unequally spaced spiral blade 131 to enter the strip filter hole 123 above. The width of the strip filter hole 123 is smaller than the maximum width of the teardrop-shaped filter hole 122, so that the solid waste will not be blocked in the strip filter hole 123 or the circular filter hole 124 during the movement, and at the same time, it will not affect the water contained in the solid waste being filtered out under the action of gravity;

[0057] The unequally spaced spiral blades 131 rotate continuously, pushing the solid waste to the top of the circular filtering hole 124. Since the end with a narrow pitch of the unequally spaced spiral blades 131 is close to the drain port 15, the solid waste is squeezed at the same time under the action of the unequally spaced spiral blades 131, thereby further accelerating the discharge of water in the solid waste. The discharged water passes through the arc-shaped screen 12 and is discharged from the drain port 15 together with the sewage on the filtered water collecting bottom plate 14. The solid waste on the arc-shaped screen 12 is pushed to the end of the arc-shaped screen 12 by the unequally spaced spiral blades 131, and is discharged from the slag discharge port 31 at the bottom of the bottom cover 3. The wastewater is collected and separated from the sewage through interception, filtration and extrusion, and then discharged from two directions. The intercepted solid waste is collected for further treatment, and the sewage enters the screen pool and is further filtered by the screen machine. Since the large-volume and irregular-shaped solid waste has been filtered out, the pressure of the screen machine to filter the sewage is reduced. By intercepting the solid waste, it is effectively avoided that the minced meat or bone residue is stuck on the rake teeth, and the screen machine is prevented from being blocked. The interception efficiency is high, the solid waste is pushed and automatically discharged, it is easy to use, and the cleaning and maintenance are easy. It has a wide range of promotion and application value in the field of slaughterhouse wastewater treatment technology.
