Description

Technical Field

[0001] This application relates to the technical field of wastewater treatment, and in particular to a weighing and metering device. Background Technology

[0002] The production of insulation boards typically generates a large amount of wastewater. To reduce environmental pollution, wastewater treatment is usually necessary. The wastewater treatment tank is equipped with a discharge hopper, with an inlet pipe on the upper side of the hopper and a discharge pipe connected to the inside of the wastewater treatment tank on the lower side. During treatment, workers transport the wastewater to the discharge hopper through the inlet pipe and then to the wastewater treatment tank for further processing via the discharge pipe.

[0003] Since wastewater treatment usually requires adding a treatment agent in proportion to the amount of wastewater in the wastewater treatment tank, the method of manually controlling the amount of wastewater entering the wastewater treatment tank is prone to errors, which can adversely affect the wastewater treatment effect. Utility Model Content

[0004] In order to reduce the adverse effects on wastewater treatment, this application provides a weighing and metering device.

[0005] The weighing and measuring device provided in this application adopts the following technical solution:

[0006] A weighing and metering device includes a hopper, an inlet pipe installed on the upper side of the hopper, and a drain pipe installed on the lower side of the hopper. A meter is installed in the middle of one side of the hopper, and metering devices are also installed at both ends of the hopper away from the metering devices. A support frame is sleeved and installed on the outside of the hopper. All metering devices are installed on the support frame. A first control valve is installed on the inlet pipe, and a second control valve is installed on the drain pipe.

[0007] By adopting the above technical solution, the first control valve is opened and wastewater is added to the discharge hopper through the inlet pipe. The weight of the wastewater in the discharge hopper is monitored by a meter. When the weight of the wastewater in the discharge hopper matches the weight of the wastewater treated in a single batch, the first control valve closes the inlet pipe, and the second control valve opens the discharge pipe to facilitate the discharge of the wastewater in the discharge hopper through the discharge pipe. This facilitates accurate control of the amount of wastewater treated in a single batch. After the wastewater in the discharge hopper is discharged, the inlet pipe is opened again and the discharge pipe is closed to facilitate the addition of wastewater to the discharge hopper. Furthermore, the meter measures the wastewater at three points on the lower side of the discharge hopper, improving the stability of the metering and reducing the adverse effects on the accuracy of the metering, thus reducing the adverse effects on the wastewater treatment effect.

[0008] Optionally, two water discharge pipes are provided, both of which are connected to the discharge hopper, and a corresponding treatment tank is installed at the end of each water discharge pipe away from the discharge hopper.

[0009] By adopting the above technical solution, the treatment tank is connected to the discharge hopper through the corresponding discharge pipe, which facilitates the alternating discharge of wastewater from the discharge hopper into the treatment tank for treatment, thereby improving the wastewater treatment efficiency.

[0010] Optionally, both sides of the lower end of the hopper are provided with inclined surfaces that gradually slope towards each other from top to bottom.

[0011] By adopting the above technical solution, when the wastewater in the discharge hopper is discharged through the discharge pipe, the inclined surfaces on both sides of the discharge hopper make it easy for the wastewater in the discharge hopper to move to the discharge pipe and be discharged, reducing the possibility of wastewater accumulating in the discharge hopper and reducing the adverse effects on the wastewater treatment effect.

[0012] Optionally, the upper side of the discharge hopper is open, and the end of the water inlet pipe near the discharge hopper is inserted into the discharge hopper and inclined towards the discharge hopper.

[0013] By adopting the above technical solution, the bent and inclined end of the inlet pipe allows wastewater to flow into the discharge hopper along the inclined surface on the side wall of the discharge hopper when it is discharged, reducing the possibility of wastewater splashing out and further reducing the adverse effects on the wastewater treatment effect.

[0014] Optionally, the hopper is provided with mounting plates corresponding to the metering devices, and each mounting plate is detachably connected to the corresponding metering device.

[0015] By adopting the above technical solution, the metering devices are all installed on the discharge hopper via mounting plates. When a metering device is damaged, the damaged metering device is unfixed to the corresponding mounting plate, which facilitates the disassembly of the damaged metering device and the replacement of the new metering device, thereby reducing the adverse impact on the accuracy of wastewater metering in the discharge hopper and reducing the adverse impact on the wastewater treatment effect.

[0016] Optionally, the mounting plate has a plug-in slot on its lower side that is compatible with the meter, the metering end is inserted into the plug-in slot, and the mounting plate is provided with a fixing component for fixing the meter.

[0017] By adopting the above technical solution, the end of the meter is inserted into the insertion slot on the lower side of the corresponding mounting plate. At this time, the meter is fixed to the corresponding mounting plate by the fixing component, which makes it easy to quickly install the meter on the discharge hopper. When the meter needs to be replaced, the fixing component is used to release the fixing between the meter and the corresponding mounting plate, and the end of the meter is pulled out, which facilitates the installation and disassembly of the meter and improves work efficiency.

[0018] Optionally, the fixing component includes a plug plate slidably connected to one side of the mounting plate. The end of the meter that is inserted into the plug slot is provided with a mounting groove. The plug plate is inserted into the mounting groove. A screw is provided on the mounting plate that passes through the plug plate and the end of the meter that is inserted into the plug slot. One end of the screw is provided with a limiting block, and the other end is equipped with a nut.

[0019] By adopting the above technical solution, the end of the meter is inserted into the insertion slot. At this time, the drive plate moves the screw towards the end of the meter until the insertion plate is inserted into the mounting slot. Then, the screw is turned until the end of the screw passes through the end of the meter and the side of the mounting plate away from the insertion plate. At this time, the limiting block abuts against the side of the mounting plate near the insertion plate. The nut is installed on the end of the screw away from the limiting block, which makes it easier to install the meter on the corresponding mounting plate and improves work efficiency.

[0020] Optionally, the outer side of the discharge hopper is provided with a support plate that is slidably connected to the support frame, and the outer side of the discharge hopper is provided with a fixing plate corresponding to the support plate in the circumferential direction. The support plate can contact the fixing plate, and the support frame is provided with a hydraulic cylinder that drives the support plate to move closer to the fixing plate.

[0021] By adopting the above technical solution, when the metering device is damaged and needs to be replaced, the end of the metering device and the corresponding mounting plate are both unfixed. The hydraulic cylinder drives the support plate to move closer to the fixed plate until it abuts against the fixed plate. At this time, the telescopic rod of the hydraulic cylinder continues to extend and drives the discharge hopper to move upward through the support plate and the fixed plate, which facilitates the replacement of the metering device and improves work efficiency.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] The weight of wastewater in the discharge hopper is monitored by a meter. When the weight of wastewater in the discharge hopper matches the weight of wastewater treated in a single batch, the first control valve closes the inlet pipe and the second control valve opens the outlet pipe, which facilitates the discharge of wastewater from the discharge hopper through the outlet pipe. This allows for accurate control of the amount of wastewater treated in a single batch. Furthermore, the meter measures the wastewater at three points on the lower side of the discharge hopper, which improves the stability of the measurement and reduces the adverse effects on the accuracy of the measurement, thus reducing the adverse effects on the wastewater treatment effect.

[0024] The bend and inclination of the inlet pipe allows wastewater to flow into the discharge hopper along the inclined surface on the side wall of the discharge hopper when it is discharged, reducing the possibility of wastewater splashing out and further reducing the adverse effects on the wastewater treatment effect.

[0025] All meters are mounted on the discharge hopper via mounting plates. When a meter is damaged, the damaged meter is removed from the corresponding mounting plate, making it easy to disassemble and replace the damaged meter with a new one. This reduces the adverse impact on the accuracy of wastewater metering in the discharge hopper and the overall wastewater treatment effect. Attached Figure Description

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses a weighing and measuring device. Example

[0034] Reference Figure 1 and Figure 2 A weighing and metering device includes a support frame 1, with four support legs (not shown in the figure) installed at the four corners of the lower side of the support frame 1. The upper part of the support frame 1 has an opening in the middle, and a vertical discharge hopper 2 is installed on the support frame 1 at the opening. The upper end of the discharge hopper 2 is open and passes through the support frame 1. The upper end of the discharge hopper 2 is provided with a water inlet pipe 21 for conveying wastewater into the discharge hopper 2. The water inlet pipe 21 is installed on the upper side of the support frame 1 (not shown in the figure), and a first control valve 211 is installed on the water inlet pipe 21.

[0035] The lower end of the discharge hopper 2 is located on the lower side of the upper end of the support frame 1, and the lower end of the discharge hopper 2 is fixedly connected to and connected to two vertical water discharge pipes 22. The water discharge pipes 22 are all located in the middle of the lower end of the discharge hopper 2, and a second control valve 221 is installed on each water discharge pipe 22. The lower end of each water discharge pipe 22 is connected to a treatment tank (not shown in the figure) corresponding to the water discharge pipe 22.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The feeding hopper 2 has a meter 3 installed on the upper side of the support frame 1 in the middle of one side along its own length direction, and the feeding hopper 2 also has meter 3 installed on the upper side of the support frame 1 on both sides along its own width direction. The line connecting adjacent meter 3 forms an isosceles triangle on the horizontal plane.

[0037] Vertical mounting plates 4, corresponding one-to-one with the metering devices 3, are fixedly connected to the side walls of the hopper 2 and the metering device 3. The lower side of the mounting plates 4 is bent towards the corresponding metering device 3 to a horizontal position. Two bolts 41 are provided at the bent end of the mounting plates 4. The line connecting the bolts 41 is parallel to the length direction of the bent end of the mounting plates 4. The bent end of the mounting plates 4 is detachably connected to the corresponding metering device 3 through the bolts 41.

[0038] The first control valve 211 is opened and wastewater is put into the discharge hopper 2 through the inlet pipe 21. The weight of the wastewater in the discharge hopper 2 is monitored by the meter 3. When the weight of the wastewater in the discharge hopper 2 is consistent with the weight of the wastewater treated in a single batch, the first control valve 211 closes the inlet pipe 21 and the second control valve 221 opens the discharge pipe 22 to facilitate the discharge of the wastewater in the discharge hopper 2 through the discharge pipe 22. The treatment tank is connected to the discharge hopper 2 through the corresponding discharge pipe 22, so that the wastewater in the discharge hopper 2 can be alternately discharged into the treatment tank for treatment, thereby improving the wastewater treatment efficiency.

[0039] After the wastewater in the discharge hopper 2 is discharged, the inlet pipe 21 is opened again and the outlet pipe 22 is closed to facilitate the addition of wastewater into the discharge hopper 2. The meter 3 measures the wastewater at three points on the lower side of the discharge hopper 2, which facilitates accurate control of the amount of wastewater treated in a single process and improves the stability of the metering.

[0040] All metering devices 3 are mounted on the discharge hopper 2 via mounting plates 4. When a metering device 3 is damaged, the damaged metering device 3 is removed from the corresponding mounting plate 4 by bolts 41, which facilitates the disassembly of the damaged metering device 3 and the replacement of a new metering device 3, thereby reducing the adverse impact on the accuracy of wastewater metering in the discharge hopper 2.

[0041] Reference Figure 2 and Figure 3The lower end of one side of the discharge hopper 2, which is set along its own length, gradually slopes towards the discharge pipe 22, and the lower end of the other side of the discharge hopper 2, which is set along its own length, also gradually slopes towards the discharge pipe 22. The inlet pipe 21 is set along the width of the discharge hopper 2, and the end of the inlet pipe 21 near the discharge hopper 2 is bent downward and inserted into the discharge hopper 2. The bent end of the inlet pipe 21 is located above the inclined surface on the side of the discharge hopper 2 where the metering device 3 is installed, and the bent end of the inlet pipe 21 slopes towards the end of the discharge hopper 2 in the horizontal direction.

[0042] When the wastewater in the discharge hopper 2 is discharged through the discharge pipe 22, the inclined surfaces on both sides of the discharge hopper 2 make it easy for the wastewater in the discharge hopper 2 to move to the discharge pipe 22 and be discharged, reducing the possibility of wastewater accumulating in the discharge hopper 2. In addition, the bent and inclined end of the inlet pipe 21 makes the wastewater flow into the discharge hopper 2 along the inclined surface on the side wall of the discharge hopper 2 when it is discharged into the discharge hopper 2, reducing the possibility of wastewater splashing out.

[0043] The implementation principle of Example 1 is as follows: Wastewater is put into the discharge hopper 2 through the inlet pipe 21. The weight of the wastewater in the discharge hopper 2 is monitored by the meter 3. When the weight of the wastewater in the discharge hopper 2 is consistent with the weight of the wastewater treated in a single batch, the first control valve 211 closes the inlet pipe 21 and the second control valve 221 opens the discharge pipe 22 to facilitate the discharge of the wastewater in the discharge hopper 2 through the discharge pipe 22. After the wastewater in the discharge hopper 2 is discharged, the inlet pipe 21 is opened again and the discharge pipe 22 is closed to facilitate the addition of wastewater to the discharge hopper 2. This facilitates accurate control of the amount of wastewater treated in a single batch and improves the stability of the metering. Example

[0044] Reference Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that the lower side of the bent end of the mounting plate 4 is provided with a plug groove 42 that is adapted to the corresponding measuring device 3 and is arranged along the length direction of the bent end of the mounting plate 4. The opening of the plug groove 42 faces downward, and the end of the corresponding measuring device 3 is inserted into the plug groove 42. The mounting plate 4 is provided with a fixing component 5 for fixing the corresponding measuring device 3.

[0045] Horizontal fixed plates 23 are fixedly connected to both ends of the discharge hopper 2 in the horizontal direction, with the sides furthest from each other. Two horizontal support plates 11, corresponding one-to-one with the fixed plates 23, are provided on the upper side of the support frame 1. The sides of the support plates 11 furthest from each other are bent upwards at right angles. Two symmetrically arranged and vertically aligned hydraulic cylinders 12 are fixedly connected to the lower side of the upper end of the support frame 1. The telescopic rods of the hydraulic cylinders 12 pass through the support frame 1 and are fixedly connected to the support plates 11. When the support plates 11 contact the fixed plates 23 and drive the discharge hopper 2 to move upwards, the sides of the fixed plates 23 furthest from each other contact the bent ends of the support plates 11.

[0046] When the metering device 3 is damaged and needs to be replaced, the end of the metering device 3 and the corresponding mounting plate 4 are both unfixed. The hydraulic cylinder 12 drives the support plate 11 to move closer to the fixing plate 23 until it abuts against the fixing plate 23. At this time, the telescopic rod of the hydraulic cylinder 12 continues to extend and drives the discharge hopper 2 to move upward through the support plate 11 and the fixing plate 23, so that the damaged metering device 3 can be removed. The end of the new metering device 3 is inserted into the insertion slot 42 on the lower side of the corresponding mounting plate 4. At this time, the metering device 3 and the corresponding mounting plate 4 are fixed by the fixing component 5. The telescopic rod of the hydraulic cylinder 12 retracts and resets the discharge hopper 2, thereby guiding the discharge hopper 2 and reducing the possibility of the discharge hopper 2 shifting.

[0047] Reference Figure 4 and Figure 5 The fixing component 5 includes a horizontal insertion plate 51 that corresponds to and is inserted into and slidably connected to one bent end of the mounting plate 4. The insertion plate 51 is located on one side of the corresponding mounting plate 4. One end of the meter 3 is inserted into the insertion slot 42, and a mounting slot 31 is provided on the side near the insertion plate 51. The side of the insertion plate 51 near the corresponding meter 3 can be inserted into the mounting slot 31.

[0048] A horizontal screw 52, ​​which is slidably connected to the plug plate 51 and is positioned along the width of the mounting plate 4, is inserted through the meter 3 and into the plug slot 42 of the meter 3 and the mounting plate 4. A limit block 53 is fixedly connected to the end of the screw 52 near the plug plate 51, and a nut 54 is threadedly connected to the end of the screw 52 that passes through the mounting plate 4.

[0049] When the screw 52 fixes the meter 3, one side of the plug plate 51 is inserted into the mounting groove 31, the limiting block 53 abuts against the side wall of the plug plate 51, and the end of the screw 52 away from the limiting block 53 is threadedly connected to the nut 54.

[0050] Insert the end of the meter 3 into the insertion slot 42. At this time, drive the insertion plate 51 to move the screw 52 towards the end of the meter 3 until the insertion plate 51 is inserted into the mounting slot 31. Drive the screw 52 through the end of the meter 3 and the side of the mounting plate 4 away from the insertion plate 51. At this time, the limiting block 53 abuts against the side of the mounting plate 4 near the insertion plate 51. Install the nut 54 on the end of the screw 52 away from the limiting block 53 to facilitate the installation of the meter 3 on the corresponding mounting plate 4 and improve work efficiency.

[0051] The implementation principle of Example 2 is as follows: The end of the meter 3 is inserted into the insertion slot 42, and the insertion plate 51 is driven to move the screw 52 until the insertion plate 51 is inserted into the mounting slot 31. The screw 52 passes through the end of the meter 3 and the side of the mounting plate 4 away from the insertion plate 51. At this time, the limiting block 53 abuts against the side of the mounting plate 4 near the insertion plate 51. The nut 54 is installed on the end of the screw 52 away from the limiting block 53, which makes it easier to install the meter 3 on the corresponding mounting plate 4 and improves work efficiency.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
