Description

Technical Field

[0001] The utility model relates to the field of auxiliary components for kitchen waste water treatment, and particularly relates to an automatic kitchen waste water slag remover. Background Art

[0002] A large amount of catering waste water is generated in various places such as canteens in government agencies, university restaurants, and kitchens in hotel catering enterprises. When the catering waste water is discharged, in order to meet the discharge standards, oil separation equipment and grease separators are usually used to perform deoiling treatment on the kitchen waste water. However, since the kitchen waste water usually contains residues and garbage with a diameter greater than 3 mm, such as vegetable leaves, blocky food, plastic garbage, chopsticks, toothpicks, mop heads, fish bones, etc., if these residues are not filtered initially, it is extremely easy to affect the separation effect of the subsequent grease separator equipment due to excessive residues in the kitchen waste water, directly resulting in the unqualified quality of the sewage discharged into the municipal pipeline. Content of the Utility Model

[0003] The purpose of the utility model is to provide an automatic kitchen waste water slag remover to solve the above problems. Inside the slag remover box body, the internal space on both sides is divided into a slag removal bin and a slag collection bin by a vertically erected partition board. In this way, the filter screen in the slag removal bin can filter and intercept residues and garbage with a diameter greater than 3 mm contained in the sewage discharged from the kitchen, achieving the direct filtration and collection of more than 90% of the large particle residues in the sewage before the kitchen sewage flows into the municipal pipe network or the oil-water separator equipment, thereby reducing the organic matter content in the sewage. See the following for details.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] An automatic kitchen waste water slag remover provided by the utility model includes a slag remover box body. The internal space on both sides of the slag remover box body is divided into a slag removal bin and a slag collection bin by a partition board erected longitudinally. The top end of the partition board is lower than the inner bottom surface of the slag remover box body. A filter screen with its axis arranged longitudinally is installed in the slag removal bin. The filter screen is a semi-cylindrical filter screen that is open at the front and back, and its top edge is flush with the top edge of the partition board. The front end of the filter screen is fixedly connected and closed with the inner front surface of the slag remover box body. The water inlet pipe at the front of the slag remover box body is communicated with the filter screen. An overflow screen is coaxially fixed at the rear end of the filter screen. At the same time, the water outlet pipe at the rear of the slag remover box body is communicated with the space in the slag removal bin that is lower than the filter screen and the overflow screen;

[0006] The slag removal bin is combined with a slag cleaning and removing component, which is used to sweep, push and clean the residues inside the filter screen to the top edge of the filter screen through the slag cleaning and removing component and discharge them into the slag collection bin through the top edge of the partition board.

[0007] Preferably, a slag discharge pipe is vertically fixed to the inner bottom surface of the deslagger box body, and the slag discharge pipe is communicated with the slag collection bin. The front and rear positions of the inner bottom of the slag collection bin are both slopes, so as to concentrate the residues in the slag collection bin along the trend to the slag discharge pipe and then discharge them downward.

[0008] Preferably, a slag collection bucket for receiving and collecting residues is detachably combined at the bottom end of the slag discharge pipe, and a slag discharge valve for controlling opening and closing is combined and installed outside the slag discharge pipe.

[0009] Preferably, the cleaning and deslagging assembly includes a reduction motor and a driving rod. The reduction motor is longitudinally fixed to the rear part of the deslagger box body through a machine base. The driving rod coincides with the central axis of the filter screen and is longitudinally rotatably connected between the front and rear inner walls of the deslagger box body. At the same time, the rear end of the driving rod is coaxially fixed to the motor shaft of the reduction motor. Connecting rods are radially extended and fixed at the front and rear positions of the periphery of the driving rod, and the bottom ends of the connecting rods are fixedly connected to the top surface of the mounting frame arranged longitudinally. A slag removal brush arranged longitudinally is fixedly installed at the lower part of the mounting frame, and the bottom end of the slag removal brush is in close contact with the inner periphery of the filter screen, so as to sweep and push the residues on the inner periphery of the filter screen to the top edge of the filter screen and discharge them into the slag collection bin through the top edge of the partition board by driving the driving rod and the slag removal brush to reciprocate and rotate by the reduction motor.

[0010] Preferably, the rotation speed range of the reduction motor is 5-10 revolutions per minute.

[0011] Preferably, the mounting frame is an inverted U-shaped clamp, and the longitudinal length of the slag removal brush is the same as the axial length of the filter screen.

[0012] Preferably, a slag pushing rod is rotatably connected to the inner wall of the deslagger box body far away from the partition board through a plurality of connecting pieces. The slag pushing rod is a U-shaped rod, one side of which is connected to the connecting piece, and the other side is placed on the top surface of the partition board, so as to set the slag pushing rod according to the law that the hypotenuse of a right triangle is longer than the right angle side.

[0013] When using the above-mentioned automatic slag remover for kitchen waste water, specifically for removing slag from kitchen waste water, the kitchen waste water enters the slag remover box through the water inlet pipe. Since the internal space on both sides is divided into a slag removal bin and a slag collection bin by the vertical partition plate inside the slag remover box, the filter screen in the slag removal bin can filter and intercept residues and garbage with a diameter greater than 3 mm in the sewage discharged from the kitchen. It realizes the direct filtration and collection of more than 90% of the large particle residues in the sewage before the kitchen sewage flows into the municipal pipe network or the oil-water separator equipment, thereby reducing the organic matter content in the sewage, achieving the effect of purifying the sewage quality and reducing the relevant parameters of sewage BOD and COD. And assisting the use of the oil separator equipment at the rear end can effectively reduce the mixing rate of residues and oil in the equipment, thereby improving the oil-water separation effect, reducing the oil content in the kitchen sewage, slowing down the influence of excessive oil accumulation in the municipal pipe network on the drainage volume of the pipe network, and alleviating the pressure of the subsequent sewage treatment. At the same time, the way of overflowing water through the overflow screen behind the filter screen can timely overflow the sewage to the water outlet pipe and discharge it when the filter screen is blocked, avoiding water leakage accidents. And because the slag removal bin is combined with the cleaning and slag removal component, and the slag removal brush of the cleaning and slag removal component is attached to the inner circumference of the filter screen, the way that the reduction motor of the cleaning and slag removal component drives the driving rod and the slag removal brush to rotate back and forth can make the slag removal brush sweep and push the residues on the inner circumference of the filter screen to the top edge of the filter screen and discharge them into the slag collection bin through the top edge of the partition plate. At the same time, the way of sweeping and pushing the residues by the filter screen can squeeze the residues to extrude the excess sewage, realizing the effective automatic cleaning of the filtered residues and reducing the water content of the residues, facilitating the centralized collection of kitchen waste residues. And because the slag pushing rod of the cleaning and slag removal component is rotatably connected to the inner wall of the slag remover box through the connecting piece, and the slag pushing rod is set according to the law that the hypotenuse of a right triangle is longer than the right angle side. Specifically, the slag pushing rod corresponds to the hypotenuse of the right triangle structure, the inner wall of the slag remover box where the connecting piece is installed corresponds to the short right angle side of the right triangle, and the top of the filter screen corresponds to the long right angle side of the right triangle. Then when the slag removal brush rotates to lift the slag pushing rod, the angle of the slag pushing rod gradually runs to the horizontal height and extends the slag pushing distance to the slag collection bin, so that the residues swept up by the slag removal brush can be assisted to be pushed into the slag collection bin by the slag pushing rod, realizing the auxiliary cleaning of the slag removal brush and facilitating the more efficient entry of the filtered residues into the slag collection bin. And after the slag removal brush rotates to a certain angle and separates from the slag pushing rod, the slag pushing rod will automatically fall back to its original position to facilitate the cyclic cleaning of the slag removal brush.

[0014] The beneficial effects are as follows: 1. Inside the deslagging device box body, the internal space on both sides is separated into a deslagging bin and a slag collection bin by a vertically erected partition board. In this way, the filter screen in the deslagging bin can filter and intercept the residues and garbage with a diameter greater than 3 mm contained in the kitchen wastewater discharged. It realizes directly filtering and collecting more than 90% of the large-particle residues in the wastewater before the kitchen wastewater flows into the municipal pipe network or the oil-water separator device, thereby reducing the organic matter content in the wastewater, achieving the effect of purifying the wastewater quality and reducing the relevant parameters of BOD and COD in the wastewater. And assisting the use of the external grease separator device at the rear end can effectively reduce the mixing rate of residues and grease in the device, thereby improving the oil-water separation effect, reducing the oil content in the kitchen wastewater, slowing down the influence of excessive grease accumulation on the drainage volume of the municipal pipe network, and alleviating the pressure of the subsequent wastewater treatment. At the same time, the way of overflowing water through the overflow screen behind the filter screen can timely overflow the wastewater to the outlet pipe and discharge it when the filter screen is blocked, avoiding water leakage accidents;

[0015] 2. The deslagging bin is combined with a deslagging and cleaning component. At the same time, the deslagging brush of the deslagging and cleaning component is attached to the inner circumference of the filter screen. In this way, by driving the driving rod and the deslagging brush to reciprocate and rotate by the reduction motor of the deslagging and cleaning component, the deslagging brush can sweep and push the residues on the inner circumference of the filter screen to the top edge of the filter screen and discharge them into the slag collection bin through the top edge of the partition board. At the same time, by sweeping and pushing the residues through the filter screen, the residues can be squeezed to extrude the excess wastewater, realizing the effective automatic cleaning of the filtered residues and reducing the water content of the residues, which is convenient for the centralized collection of kitchen residues;

[0016] 3. The slag pushing rod of the deslagging and cleaning component is rotationally connected to the inner wall of the deslagging device box body through a connecting piece. At the same time, the slag pushing rod is set according to the law that the hypotenuse of a right triangle is longer than the right angle side. Then, when the deslagging brush rotates to lift the slag pushing rod, the angle of the slag pushing rod gradually runs to the horizontal height and extends the slag pushing distance to the slag collection bin. In this way, it can assist in pushing the residues brought up by the deslagging brush to the slag collection bin, realizing the auxiliary cleaning of the deslagging brush, facilitating the more efficient entry of the filtered residues into the slag collection bin. Moreover, after the deslagging brush rotates to a certain angle and separates from the slag pushing rod, the slag pushing rod will automatically fall back to its original position to facilitate the cyclic cleaning of the deslagging brush.

[0022] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without making creative efforts fall within the scope protected by the present utility model.

[0023] Refer to Figure 1 - Figure 2 As shown, the present utility model provides an automatic deslagging device for kitchen wastewater, including a deslagging device box body 1. The inner part of the deslagging device box body 1 is divided into a deslagging bin 2 and a slag collection bin 5 by a partition board 3 erected longitudinally along the vertical direction. The top end of the partition board 3 is lower than the inner bottom surface of the deslagging device box body 1. A filter net 202 with its axis arranged longitudinally is installed in the deslagging bin 2. The filter net 202 is a semi-cylindrical filter net that is open at the front and back, and its top edge is flush with the top edge of the partition board 3. The front end of the filter net 202 is fixedly connected and closed with the inner front surface of the deslagging device box body 1, and the water inlet pipe 101 at the front part of the deslagging device box body 1 is communicated with the filter net 202. A coaxial overflow net 201 is fixedly installed at the rear end of the filter net 202. At the same time, the water outlet pipe 102 at the rear part of the deslagging device box body 1 is communicated with the space in the deslagging bin 2 that is lower than the filter net 202 and the overflow net 201. The purpose of such a setting is that the filter net 202 in the deslagging bin 2 can filter and intercept residues and garbage with a diameter greater than 3 mm contained in the sewage discharged from the kitchen. At the same time, when the filter net 202 is blocked, the sewage can be overflowed to the water outlet pipe 102 for discharge in time through the overflow of the overflow net 201 at the rear of the filter net 202.

[0024] Refer to Figure 1 - Figure 2As shown in the figure, a cleaning and slag removal component 4 is assembled in the slag removal bin 2. The cleaning and slag removal component 4 is used to sweep and push the residues inside the inner circumference of the filter screen 202 to the top edge of the filter screen 202 and discharge them into the slag collection bin 5 through the top edge of the partition plate 3. Specifically, the cleaning and slag removal component 4 includes a reduction motor 407 and a driving rod 403. The reduction motor 407 is longitudinally fixed at the rear of the slag remover box body 1 through a machine base 408. The driving rod 403 coincides with the central axis of the filter screen 202 and is longitudinally rotatably connected between the front and rear inner walls of the slag remover box body 1. At the same time, the rear end of the driving rod 403 is coaxially fixed to the motor shaft of the reduction motor 407. Connecting rods 404 are radially extended and fixed at the front and rear positions on the periphery of the driving rod 403, and the bottom ends of the connecting rods 404 are fixedly connected to the top surface of a longitudinally arranged mounting frame 405. A slag removal brush 406 arranged longitudinally is fixedly installed at the lower part of the mounting frame 405, and the bottom end of the slag removal brush 406 is in close contact with the inner circumference of the filter screen 202. The reduction motor 407 drives the driving rod 403 and the slag removal brush 406 to reciprocate and rotate, so that the slag removal brush 406 sweeps and pushes the residues inside the inner circumference of the filter screen 202 to the top edge of the filter screen 202 and discharges them into the slag collection bin 5 through the top edge of the partition plate 3. The function of this setting is that the reduction motor 407 of the cleaning and slag removal component 4 drives the driving rod 403 and the slag removal brush 406 to reciprocate and rotate, enabling the slag removal brush 406 to sweep and push the residues inside the inner circumference of the filter screen 202 to the top edge of the filter screen 202 and discharge them into the slag collection bin 5 through the top edge of the partition plate 3. At the same time, by sweeping and pushing the residues through the filter screen 202, the residues can be squeezed to extrude excess sewage, realizing the effective automatic cleaning of the filtered residues and reducing the water content of the residues.

[0025] See Figure 2 As shown in the figure, the following optimizations are carried out on the slag remover box body 1 and the cleaning and slag removal component 4 respectively. Specifically for the slag remover box body 1, a slag discharge pipe 501 is vertically fixed on the inner bottom surface of the slag remover box body 1, and the slag discharge pipe 501 is communicated with the slag collection bin 5. The front and rear positions at the bottom of the slag collection bin 5 are both slopes, so as to concentrate the residues in the slag collection bin 5 to the slag discharge pipe 501 along the trend and then discharge them downward. In this way, it is convenient to discharge the kitchen waste residues in the slag collection bin 5 to the outside through the slag discharge pipe 501. At the same time, optionally, a slag collection bucket 503 for receiving and collecting residues is detachably assembled at the bottom end of the slag discharge pipe 501, and a slag discharge valve 502 for controlling opening and closing is assembled outside the slag discharge pipe 501. With such a setting, first, it is convenient to collect the kitchen waste residues through the slag collection bucket 503, and at the same time, it is convenient to control the opening and closing of the slag discharge pipe 501 through the slag discharge valve 502.

[0026] See Figure 1 - Figure 2As shown, specifically for the slag cleaning and removal component 4, the rotational speed range of the reduction motor 407 is 5-10 revolutions per minute to ensure that the slag cleaning brush 406 has a stable slag scraping speed and extrusion effect. Optionally, the mounting bracket 405 is an inverted U-shaped clamp, and the longitudinal length of the slag cleaning brush 406 is the same as the axial length of the filter screen 202. With such a setting, it is convenient to firmly install the slag cleaning brush 406 by means of the mounting bracket 405, and at the same time, it is convenient for the slag cleaning brush 406 to have a sufficient length for cleaning residues. Further optionally, on the inner wall of the slag remover box body 1 away from the partition plate 3, a slag pushing rod 402 is rotatably connected through a plurality of connecting pieces 401. Optionally, the connecting piece 401 is a supporting member of a bearing seat, and the slag pushing rod 402 is a U-shaped rod, with one side connected to the connecting piece 401 and the other side placed on the top surface of the partition plate 3. The slag pushing rod 402 is set according to the law that the hypotenuse of a triangle is longer than the right angle side. The advantage of such a setting is that when the slag cleaning brush 406 rotates to lift the slag pushing rod 402, the angle of the slag pushing rod 402 gradually runs to the horizontal height and extends the slag pushing distance to the slag collection bin 5, so as to assist in pushing the residues swept up by the slag cleaning brush 406 to the slag collection bin 5, realizing the auxiliary cleaning of the slag cleaning brush 406, facilitating the more efficient entry of the filtered residues into the slag collection bin 5. At the same time, when the slag cleaning brush 406 rotates to a certain angle and separates from the slag pushing rod 402, the slag pushing rod 402 will automatically fall back to its original position to facilitate the cyclic cleaning of the slag cleaning brush 406. More specifically, after the included angle between the running angle of the slag cleaning brush 406 and the horizontal plane is greater than 20°, the slag pushing rod 402 falls back to its original position and waits for the next operation cycle of the slag cleaning brush 406.

[0027] With the above structure, specifically when used for slag removal treatment of kitchen wastewater, the kitchen wastewater enters the slag remover box body 1 through the water inlet pipe 101. Since the internal space on both sides is divided into a slag removal bin 2 and a slag collection bin 5 by the vertical partition plate 3 inside the slag remover box body 1, the filter screen 202 in the slag removal bin 2 can filter and intercept the residues and garbage with a diameter greater than 3 mm contained in the sewage discharged from the kitchen. It realizes that more than 90% of the large particle residues in the sewage are directly filtered and collected before the kitchen sewage flows into the municipal pipe network or the oil-water separator equipment, thereby reducing the organic matter content in the sewage, achieving the effect of purifying the sewage quality and reducing the relevant parameters of sewage BOD and COD. And when used in conjunction with the oil separator equipment at the back end, it can effectively reduce the mixing rate of residues and oil in the equipment, thereby improving the oil-water separation effect, reducing the oil content in the kitchen sewage, slowing down the impact of excessive oil accumulation in the municipal pipe network on the drainage volume of the pipe network, and alleviating the pressure on the subsequent sewage treatment. At the same time, when the sewage overflows through the overflow screen 201 behind the filter screen 202, it can overflow the sewage to the water outlet pipe 102 in time when the filter screen 202 is blocked, avoiding water leakage accidents. And because the slag removal bin 2 is combined with a cleaning and slag removal assembly 4, and the slag removal brush 406 of the cleaning and slag removal assembly 4 is attached to the inner circumference of the filter screen 202, by driving the drive rod 403 and the slag removal brush 406 to rotate reciprocally through the reduction motor 407 of the cleaning and slag removal assembly 4, the slag removal brush 406 can sweep and push the residues on the inner circumference of the filter screen 202 to the top edge of the filter screen 202 and discharge them into the slag collection bin 5 through the top edge of the partition plate 3. At the same time, by sweeping and pushing the residues by the filter screen 202, the residues can be squeezed to extrude the excess sewage, realizing the effective automatic cleaning of the filtered residues and reducing the water content of the residues, facilitating the centralized collection of kitchen residues. And because the slag pushing rod 402 of the cleaning and slag removal assembly 4 is rotatably connected to the inner wall of the slag remover box body 1 through the connecting piece 401, and the slag pushing rod 402 is set according to the law that the hypotenuse of a right triangle is longer than the right angle side. Specifically, the slag pushing rod 402 corresponds to the hypotenuse of the right triangle structure, the inner wall of the slag remover box body 1 where the connecting piece 401 is installed corresponds to the short right angle side of the right triangle, and the top of the filter screen 202 corresponds to the long right angle side of the right triangle. Then, when the slag removal brush 406 rotates to lift the slag pushing rod 402, the angle of the slag pushing rod 402 gradually runs to the horizontal height and extends the slag pushing distance to the slag collection bin 5. In this way, the slag pushed by the slag removal brush 406 can be assisted to be pushed into the slag collection bin 5, realizing the auxiliary cleaning of the slag removal brush 406, facilitating the more efficient entry of the filtered residues into the slag collection bin 5. And after the slag removal brush 406 rotates to a certain angle and separates from the slag pushing rod 4, the slag pushing rod 402 will automatically fall back to its original position to facilitate the cyclic cleaning of the slag removal brush 406.

[0028] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily conceive of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims described above.
