Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a sampling device for flocculated sediments. Background Technology
[0002] Flocculation is an aggregate formed during the flocculation process. Flocculation refers to the aggregation of suspended particles (such as clay particles, algae, bacteria, organic impurities, etc.) in water or liquid through physical or chemical processes, forming larger particle clusters, which are called flocs.
[0003] In wastewater treatment, flocculants are added to the wastewater. These flocculants undergo hydrolysis in the water. For example, polyaluminum chloride hydrolyzes in water to form aluminum hydroxide colloids. The aluminum hydroxide colloids carry a positive charge, while many suspended particles in wastewater tend to carry a negative charge. Through charge neutralization, the colloids and suspended particles attract each other.
[0004] To determine the reaction between wastewater components and flocculants, it is necessary to sample the flocs and analyze the stratification data to understand their settling velocity. Existing underwater sampling devices utilize methods such as adsorption sampling and clamping sampling. These methods may alter the stratification of the flocs; therefore, a sampling device is needed that minimizes disruption to the floc stratification during the flocculation sampling process. Utility Model Content
[0005] This utility model aims to at least partially solve one of the technical problems in the related art.
[0006] Therefore, the purpose of this utility model is to provide a sampling device for flocculated sediments that is simple and convenient to operate. The conical sampling head facilitates the device's entry into the flocculated sediments. After entering the flocculation zone, the sampling head can maintain the stratified state of the flocculated sediments. The drooping sampling head can keep the flocculated sediments in their original stratified state as they enter the collection chamber.
[0007] To achieve the above objectives, this utility model proposes a sampling device for flocculated precipitates, which may include: a sampling head, which is divided into a large cone head and a small cone head, and there are two sets of both the large and small cone heads.

Fitting sealing gaskets are provided on both sides of the large cone head, and fitting sealing gaskets are provided on both sides and the top surface of the small cone head.

[0011] The bearing is fixed to the inner wall above the collection chamber, and the center of the connecting block is connected to the inner wall of the bearing.
[0012] A torsion spring, one end of which is connected to a connecting block, and the other end of which is connected to a bearing.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0028] The sampling device for flocculated precipitates according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0030] like Figure 1-Figure 5 As shown, the sampling device for flocculated precipitates in this embodiment of the present invention may include [features].
[0031] Sampling head 1 is divided into a large cone head 101 and a small cone head 102. There are two sets of large cone heads 101 and small cone heads 102. The inner diameter of the large cone head 101 is matched with the outer diameter of the large cone head 101. The two sets of large cone heads 101 are symmetrically arranged around the axis. Fitting sealing gaskets are provided on both sides of the large cone head 101. Fitting sealing gaskets are provided on both sides and the top surface of the small cone head 102.
[0032] The sampling chamber 2 is fixed to the top of the sampling head 1.
[0033] The outer wall of the circular slide rail 3 is fixed to the inner wall of the collection chamber 2. The top of the small cone 102 is fixed with a sliding shaft 4, which is slidably connected to the inner wall of the circular slide rail 3.
[0034] The connecting block 5 and multiple sets of sliding shafts 4 are fixed at the bottom of the connecting block 5.
[0035] Bearing 6 is fixed to the inner wall above the collection chamber 2, and the center of the connecting block 5 is connected to the inner wall of bearing 6.
[0036] Torsion spring 7, one end of which is connected to the connecting block 5, and the other end of which is connected to the bearing 6.
[0037] By turning the connecting block 5, the connecting block 5 drives the two sets of small cones 102 to rotate on the track of the circular slide rail 3. The connecting block 5 rotates on the inner wall of the collection chamber 2, the sampling head 1 is opened, the sampling head 1 hangs down naturally, and the flocculation enters the interior of the collection chamber 2. When the connecting block 5 is released, the small cones 102 retract under the action of the torsion spring 7. At this time, the sampling head 1 can be taken out, and the flocculated material in a layered state can be obtained. When the cone-shaped sampling head 1 hangs down into the flocculated material, the sampling head 1 can smoothly enter the interior of the sampling chamber and maintain the original layered state of the flocculated material.
[0038] In one embodiment of this utility model, such as Figure 1-Figure 2 As shown, a nylon line 9 is connected to the eccentric position of the connecting block 5. The threaded block 8 is fixed to the top of the connecting block. The outer surface of the threaded block 8 has a threaded groove. The nylon line 9 is wound around the inner wall of the threaded groove of the threaded block 8. The nylon line 9 is fixed to the eccentric position of the connecting block 5. The small cone block is opened by pulling the nylon line 9 on the water surface.
[0039] In one embodiment of this utility model, such as Figure 1 As shown, it also includes a multi-section lifting rod 10, which is fixed to the top of the collection chamber 2 and is used to send the sampling head 1 to the flocculation zone.
[0040] In one embodiment of this utility model, such as Figures 4-5 As shown, a crushing head 11 is fixed on the outer wall of the large cone head 101. The crushing head 11 is used to cut the flocculent material by the large cone head 101, so that the sample can be easily taken into the flocculation zone.
[0041] In one embodiment of this utility model, such as Figure 1-Figure 2 As shown, it also includes a turntable 12, with one end of the nylon line 9 wound around the turntable 12. The nylon line is pulled by rotating the turntable 12.
[0042] Specifically, after the sampling head 1 enters the flocculation zone, the flocculated material enters the collection chamber 2 by opening the small cone head 102. After releasing the cone head 102, it closes, and the sampling head can be removed to obtain the flocculated material.
[0043] In summary, the sampling device for flocculated sediments according to this utility model embodiment is simple and convenient to operate, and the conical sampling head 1 facilitates the device to enter the flocculated material. After entering the flocculation zone, the sampling head 1 can maintain the stratified state of the flocculated material. The drooping sampling head 1 can keep the flocculated material in its original stratified state when it enters the interior of the collection chamber 2.
