Description

Technical Field

[0001] The utility model belongs to the technical field of sewage sample sampling, and in particular relates to a sampling and collecting device for sewage treatment. Background Art

[0002] Wastewater treatment refers to the purification and treatment of wastewater through various physical, chemical and biological methods to remove pollutants in the wastewater and avoid its direct discharge affecting the environment. After the wastewater is treated, it needs to be tested. Usually, the wastewater is sampled and the collected samples are tested to ensure the treatment effect of the wastewater.

[0003] After searching, the Chinese patent "A Sewage Sampling and Collection Method for Wastewater Treatment in a Biological Reactor Tank" authorization announcement number "CN213933225U" places the lower end of the sampling injection tube above the glass bottle storage groove, so that sampling can be carried out without removing the sewage sample glass bottle, and transportation further avoids the probability of the surface of the sewage sample glass bottle contacting the sewage. At the same time, by setting up the glass bottle storage groove, it is convenient to fix and embed the sewage sample glass bottle in a cross shape, avoiding the sewage sample glass bottle from shaking, colliding and breaking.

[0004] Although sampling can be performed without removing the sample glass bottle in the above application, the tube mouth of the sample glass bottle is in an open state during sampling and transportation, and there is a gap between the sampling injection tube and the sample glass bottle, which will cause sample leakage during transportation, thereby affecting the sampling effect.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See also Figure 1 - Figure 5 The utility model provides a technical solution: a sampling and collecting device for sewage treatment, comprising:

[0036] A sewage sampling and storage box 1, the inner wall of which is slidably connected to a sample storage box 2, a sample glass bottle 3 is installed inside the sample storage box 2, and a sealing mechanism 4 is provided inside the sewage sampling and storage box 1;

[0037] The sealing mechanism 4 includes a bidirectional screw 41 rotatably connected to one side of the sewage sampling and storage box 1. Two movable plates 42 are threadedly connected to the surface of the bidirectional screw 41. The other side of the movable plates 42 extends into the inner side of the sewage sampling and storage box 1. A plurality of circular rings 43 distributed in equal rows are fixedly connected to the surface of each movable plate 42. A first threaded rod 44 is rotatably connected to the top side of the movable plate 42. A connecting plate 45 is threadedly connected to the surface of the first threaded rod 44. One side of the connecting plate 45 extends into the inner side of the sewage sampling and storage box 1. A plurality of sealing plugs 46 distributed in equal rows are fixedly connected to the surface of the connecting plate 45. The sealing plugs 46 correspond one-to-one to the circular rings 43 and are located inside the circular rings 43. The bottom ends of the sealing plugs 46 are curved in an arc shape.

[0038] The sealing plug 46 is made of rubber. The number of the rings 43 and the sealing plug 46 matches the number of the sample glass bottles 3 , and the positions of the rings 43 and the sealing plug 46 correspond one-to-one to the positions of the sample glass bottles 3 .

[0039] The threads of the two movable plates 42 connected to the bidirectional screw rod 41 are opposite to each other. Therefore, when the bidirectional screw rod 41 is rotated, the two movable plates 42 are driven to move toward each other.

[0040] When the device is initially installed, the ring 43 and the sealing plug 46 are away from the sample glass bottle 3, which does not affect the normal sampling operation, and the horizontal height of the bottom ends of the ring 43 and the sealing plug 46 is slightly higher than the horizontal height of the top end of the sample glass bottle 3. Therefore, when the movable plate 42 drives the ring 43 to move upwards of the sample glass bottle 3, the bottom end of the ring 43 does not contact the top end of the sample glass bottle 3.

[0041] like Figure 4 and Figure 5 As shown, the sealing mechanism 4 further includes a sealing ring 47 fixedly connected to the surface of the sealing plug 46 , and the outer diameter of the sealing ring 47 is the same as the inner diameter of the sample glass bottle 3 .

[0042] Rotating the bidirectional screw rod 41 drives the two movable plates 42 away from each other, so that the two movable plates 42 respectively drive the corresponding rings 43 and sealing plugs 46 to move toward the top of the corresponding sample glass bottle 3. When they cannot move further, the two first threaded rods 44 are rotated in turn, and the connecting plate 45 is driven downward by rotating the first threaded rod 44, thereby driving the corresponding multiple sealing plugs 46 and sealing rings 47 to enter the sample glass bottle 3 at the same time. At this time, the surface of the sealing ring 47 will fit the inner wall of the sample glass bottle 3.

[0043] like Figure 2As shown, a baffle 48 is fixedly connected to the inner wall of the sewage sampling storage tank 1. The center point of the baffle 48 and the center of one of the rings 43 are on the same vertical plane. The surface of the baffle 48 is curved into an arc. When the moving plate 42 drives the ring 43 to move above the sample glass bottle 3, when one of the rings 43 contacts the baffle 48, the bidirectional screw rod 41 cannot continue to rotate. At this time, the centers of the multiple sealing plugs 46 coincide with the centers of the corresponding sample glass bottles 3 below.

[0044] As Figure 4 shown, a limiting rod 49 is fixedly connected to one side of the top end of each of the two moving plates 42. The top end of the limiting rod 49 penetrates through the corresponding connecting plate 45, and the inner wall of the connecting plate 45 is slidably connected to the surface of the limiting rod 49. When the horizontal height of the bottom end of the sealing plug 46 is on the same horizontal plane as the horizontal height of the bottom end of the ring 43, the connecting plate 45 cannot continue to move upward under the limiting effect of the limiting rod 49.

[0045] As Figure 5 shown, a plurality of annularly distributed grooves 410 are formed in the inner wall of the ring 43. A spherical ball 411 is rotatably connected to the inner wall of the groove 410, and the surface of the spherical ball 411 contacts the surface of the sealing ring 47. When the connecting plate 45 drives the sealing plug 46 and the sealing ring 47 to move up and down, it will cause the spherical ball 411 to rotate, reducing the friction during movement.

[0046] As Figure 2 shown, two chutes 412 are formed on one side of the sewage sampling storage tank 1. The overall shape of the chute 412 is in the shape of a "匚". The shape of the chute 412 matches the movement paths of the corresponding moving plate 42 and the connecting plate 45.

[0047] As Figure 2 shown, a plurality of water inlet pipes 5 are fixedly connected to the top end of the sewage sampling storage tank 1. The bottom end of the water inlet pipe 5 penetrates into the interior of the sewage sampling storage tank 1. A second threaded rod 51 is rotatably connected to the top end of the sewage sampling storage tank 1. A rectangular frame 52 is threadedly connected to the surface of the second threaded rod 51. The surface of the water inlet pipe 5 is fixedly connected to the inner wall of the rectangular frame 52.

[0048] When sampling sewage, the bottom end of the water inlet pipe 5 extends into the inner side of the sample glass bottle 3. Connect the external water intake pipe to the water inlet pipe 5 in sequence to perform the water sampling operation. After sampling, rotate the second threaded rod 51 counterclockwise to drive the rectangular frame 52 to move upward, which can drive the plurality of water inlet pipes 5 to move upward simultaneously. When the rectangular frame 52 cannot continue to move upward, the bottom end of the water inlet pipe 5 is far away from the sample glass bottle 3, and the horizontal height of the bottom end of the water inlet pipe 5 is higher than the horizontal height of the top end of the sealing plug 46.

[0049] When the present invention is in use, sampling is first carried out through the water inlet pipe 5. After the sampling is completed, the second threaded rod 51 is rotated counterclockwise to drive multiple water inlet pipes 5 to move upward and away from the sample glass bottle 3 at the same time through the rectangular frame 52. After completing this operation, the two-way screw rod 41 is rotated to drive the two movable plates 42 to move and move away from each other, so that the two movable plates 42 respectively drive the corresponding circular rings 43 and sealing plugs 46 to move above the corresponding sample glass bottle 3. When one of the circular rings 43 contacts the baffle 48, the two-way screw rod 41 cannot continue to rotate. At this time, the center of the multiple sealing plugs 46 coincides with the center of the circle of the corresponding sample glass bottle 3 below, and the two first threaded rods 44 are rotated in turn. By rotating the first threaded rod 44, the connecting plate 45 is driven downward, thereby driving the corresponding multiple sealing plugs 46 and sealing rings 47 to move downward at the same time, so that the sealing plugs 46 and sealing rings 47 enter the corresponding sample glass bottle 3 below, and the surface of the sealing ring 47 will fit with the inner wall of the sample glass bottle 3, thereby completing the sealing of multiple sample glass bottles 3.

[0050] When it is necessary to take out the sample glass bottle 3, first reversely rotate the first threaded rod 44 to drive the sealing plug 46 and the sealing ring 47 to move upward to release the seal on the sample glass bottle 3, and then reversely rotate the two-way screw rod 41 to drive the two movable plates 42 to move closer to each other, so that the two movable plates 42 drive the corresponding rings 43 and the sealing plug 46 away from the sample glass bottle 3. At this time, open the sampling door of the sewage sampling storage box 1 to take out the sample storage box 2, and at this time, take out the sample glass bottle 3.
