Description

Technical Field

[0001] This application belongs to the field of environmental sampling equipment technology, specifically relating to a sampling device for dewatered sludge. Background Technology

[0002] With the accelerated construction of urban wastewater treatment facilities and the increasing rate of centralized wastewater treatment, the amount of sludge generated in the wastewater treatment industry has also grown dramatically. Sludge treatment follows the principle of "volume reduction," requiring dewatering to lower the sludge's moisture content before it can proceed to the next treatment stage. Sampling of dewatered sludge is a necessary step for subsequent testing and analysis.

[0003] Currently, the traditional sampling tool for dewatered sludge is a slotted thin rod. During sampling, the operator inserts the rod below the dewatered sludge discharge hopper to capture any falling sludge samples, which are then scraped into a collection bucket. However, this traditional manual sampling method has several limitations in practice, mainly in the following two aspects:

[0004] 1. Laborious operation: The entire sampling process requires operators to complete actions such as inserting the rod, extracting, and scraping the sample one by one. The physical exertion of the staff is relatively large, which can easily cause fatigue. The workload is even more obvious when frequent sampling or large-scale sample processing is required.

[0005] 2. Low sampling efficiency: In large-scale sample analysis scenarios, the amount of sludge extracted each time is small, which is time-consuming and labor-intensive, resulting in low efficiency in collecting large amounts of sludge samples.

[0006] Therefore, developing a dewatered sludge sampling device that improves the efficiency of sludge sampling and enhances the ease of operation has become a technical challenge that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] In view of the shortcomings or deficiencies of the prior art, the technical problem to be solved by this application is to provide a sampling device for dewatered sludge.

[0008] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0009] A sampling device for dewatered sludge, comprising:

[0010] The sampling tube shell has an internal receiving space and a sludge discharge port on its surface;

[0011] A recessed platform is connected to one end of the outer shell of the sampling tube, and a fixing through hole is provided inside the recessed platform;

[0012] A push rod assembly that passes through the fixed through hole and is disposed within the receiving space;

[0013] A limit block is also fixedly connected to the push rod assembly;

[0014] A sliding sleeve assembly, which is mounted at one end of the push rod assembly near the limiting block;

[0015] A bone rod support is installed in the middle of the sliding sleeve assembly, and a flexible support cloth is installed on the edge of the bone rod support.

[0016] Furthermore, the push rod assembly includes a front push rod and a rear push rod, one end of the front push rod is connected to the bone rod support, the other end of the front push rod is connected to the rear push rod, and one end of the rear push rod passes through the fixing through hole and is disposed within the receiving space.

[0017] Furthermore, the rearmost end of the push rod passes through the fixing through hole and connects to the handle.

[0018] Furthermore, the sliding sleeve assembly includes a front sliding sleeve and a rear sliding sleeve, the foremost end of the front push rod is fixedly connected to the front sliding sleeve, and the bone rod bracket is installed between the front sliding sleeve and the rear sliding sleeve.

[0019] Furthermore, the two ends of the bone rod support are connected to the rear sliding sleeve and the front sliding sleeve respectively, and the middle hinge interface is connected with screws.

[0020] Furthermore, the edge of the hinge interface is provided with a groove, and a fixing ring is provided in the groove.

[0021] Furthermore, the movable portion between the fixing ring and the bone rod support is covered by a rubber band.

[0022] Furthermore, one end of the flexible support fabric is attached to the adhesive area of ​​the front sliding sleeve, and the other end is attached to the surface of the bone rod support.

[0023] Furthermore, the limiting block includes a rear limiting block fixedly connected to the rear push rod and a front limiting block sleeved on the front push rod and located behind the rear sliding sleeve, wherein the rear limiting block is fixedly connected to the rearmost end of the front push rod and the frontmost end of the rear push rod.

[0024] Furthermore, when the handle moves forward, the bone rod support retracts backward under the action of the rear sliding sleeve, causing the supporting flexible support cloth to retract until the rear limiting block collides with the front limiting block; when the handle moves backward, the bone rod support is resisted by the sludge, gradually expanding the flexible support cloth, thereby scraping the sludge solids and allowing the sample to be discharged and collected from the sludge outlet.

[0025] Compared with the prior art, this application has the following technical effects:

[0026] In this application, when the handle moves backward, the flexible support cloth of the skeleton support is opened by the resistance of the dewatered sludge solids falling into the internal groove and the thrust of the rear sliding sleeve. During the backward movement, the flexible support cloth scrapes the sludge sample. During the sampling process, by repeatedly pushing and pulling the handle, the front push rod, the rear push rod and the skeleton support are driven to perform periodic reciprocating motion, so that the flexible support cloth unfolds or contracts under the action of the skeleton support. The collection of dewatered sludge samples can be completed through a simple push and pull action of the handle, which not only reduces the time and effort required in the operation process and greatly improves the sampling efficiency, but also improves the continuity and consistency of sampling.

[0027] In this application, the fixing ring installed in the groove at the edge of the hinge interface is covered by a rubber ring, which can effectively reduce frictional damage between the bone rod support and the internal groove of the sampling tube, improve the durability and operational stability of the device, and thus extend the service life of the device.

[0038] like Figures 1 to 4 As shown, this embodiment provides a sampling device for dewatered sludge, including:

[0039] The sampling tube housing 1 has an internal space 16 for collecting dewatered sludge samples discharged from the sludge hopper, and a sludge discharge port 2 is provided on the surface of the sampling tube housing 1.

[0040] A recessed platform 15 is connected to one end of the outer shell 1 of the sampling tube, and a fixing through hole 5 is provided inside the recessed platform 15;

[0041] The push rod assembly passes through the fixed through hole 5 and is disposed within the receiving space 16; the above arrangement helps to ensure the stability of the push rod movement direction of the push rod assembly.

[0042] A limit block is also fixedly connected to the push rod assembly;

[0043] A sliding sleeve assembly, which is mounted at one end of the push rod assembly near the limiting block;

[0044] A skeleton support 7 is installed in the middle of the sliding sleeve assembly, and a flexible support cloth 10 is installed on the edge of the skeleton support 7. The flexible support cloth 10 can be made of corrosion-resistant materials of different thicknesses to meet the sampling needs of different types of sludge; this embodiment does not make specific limitations in this regard.

[0045] Furthermore, in this embodiment, the push rod assembly includes a front push rod 18 and a rear push rod 6. One end of the front push rod 18 is connected to the bone support 7, and the other end of the front push rod 18 is connected to the rear push rod 6. One end of the rear push rod 6 passes through the fixing through hole 5 and is disposed within the receiving space 6. This arrangement helps to ensure the stability of the push rod's movement direction.

[0046] Preferably, in this embodiment, the rearmost end of the rear push rod 6 passes through the fixing through hole 5 and is connected to the handle 14. When the handle 14 is pushed forward, the rear push rod 6 and the front push rod 18 move forward, causing the bone rod support 7 to gradually retract and pull the flexible support cloth 10. The flexible support cloth 10 is resisted by the sludge sample falling into the receiving space 16, and the flexible support cloth 10 gradually closes and retracts.

[0047] Furthermore, in this embodiment, the alternating movement of the front and rear push rods controls the skeleton support 7, which drives the opening and closing of the flexible support cloth 10, thereby realizing the scraping and collection of dewatered sludge samples, which has the advantages of simple operation and high efficiency.

[0048] Preferably, in this example, the front push rod 18 and the rear push rod 6 can be made of lightweight, high-strength alloy materials to reduce the weight of the device and improve the convenience of push-pull operation.

[0049] Preferably, in this example, in order to improve sampling efficiency, one end of the push rod assembly can be driven by an electric motor to achieve fully automatic sampling of dewatered sludge.

[0050] Preferably, in this example, the handle 14 can be designed with rubber covering according to operational requirements to increase operational comfort and stability, and is especially suitable for long-term continuous sampling operations.

[0051] Furthermore, in this embodiment, the sliding sleeve assembly includes a front sliding sleeve 12 and a rear sliding sleeve 8, the foremost end of the front push rod 18 is fixedly connected to the front sliding sleeve 12, and the bone rod bracket 7 is installed between the front sliding sleeve 12 and the rear sliding sleeve 8.

[0052] Furthermore, in this embodiment, the two ends of the bone rod support 7 are respectively connected to the rear sliding sleeve 8 and the front sliding sleeve 12, and the middle hinge interface 11 is connected with screws. The screws fix the support at the hinge interface 11, allowing it to rotate freely and also serving to support the flexible support fabric 10.

[0053] Furthermore, in this embodiment, the edge of the hinge interface 11 is provided with a groove 17, and a fixing ring 13 is provided in the groove 17. The sturdy rigid structure enhances the overall support of the bone rod support 7. The fixing ring 13 is made of metal, such as alloy, stainless steel, iron, etc. This embodiment does not make specific limitations on this, as long as it can achieve the fixing function.

[0054] Furthermore, in this embodiment, the movable part between the fixing ring 13 and the bone rod support 7 is covered by a rubber ring 21.

[0055] Furthermore, in this embodiment, one end of the flexible support cloth 10 is attached to the attachment point 19 of the front sliding sleeve 12, and the other end is attached to the surface of the skeleton support 7, thereby ensuring that the sludge sample does not slip during scraping and collection. When the handle 14 is pulled back, the skeleton support 7 gradually unfolds under the support of the front sliding sleeve 12 and the rear sliding sleeve 8, as well as the resistance of the sludge sample falling into the receiving space 16, causing the flexible support cloth 10 to open. The flexible support cloth 10 then contacts the sludge sample and gradually scrapes it, discharging it through the sludge outlet 2, thus completing the sample collection process.

[0056] Furthermore, in this embodiment, the limiting block includes a rear limiting block 4 fixedly connected to the rear push rod 6 and a front limiting block 9 sleeved on the front push rod 18 and located behind the rear sliding sleeve 8, wherein the rear limiting block 4 is fixedly connected to the rear end of the front push rod 18 and the front end of the rear push rod 6.

[0057] Furthermore, in this embodiment, when the handle 14 moves forward, the bone rod support 7 retracts backward under the action of the rear sliding sleeve 8, causing the supporting flexible support cloth 10 to retract until the rear limiting block 4 collides with the front limiting block 9; when the handle 14 moves backward, the bone rod support 7 is resisted by the sludge, gradually expanding the flexible support cloth 10, thereby scraping the sludge solids and allowing the sample to be discharged and collected from the sludge outlet 2.

[0058] Preferably, in this embodiment, when the handle 14 is pushed forward to the end, the rear limiting block 4 collides with the front limiting block 9, the front limiting block 9 is in close contact with the rear sliding sleeve 8, and the flexible support cloth 10 is completely retracted.

[0059] Preferably, in this embodiment, when the handle 14 is pulled back to the end, the rear limiting block 4 collides with the inner wall 20 of the recess, and the flexible support cloth 10 is fully unfolded.

[0060] Furthermore, in this embodiment, a handle 3 is provided on one side of the sampling tube housing 1 for easy handling.

[0061] To explain the working principle of the above-mentioned dewatered sludge sampling device, a brief explanation is provided below:

[0062] The forward and backward movement of the front push rod 18 and the rear push rod 6 drives the extension and retraction of the sludge support 7 and the flexible support cloth 10, thereby achieving the scraping and collection of sludge samples in the groove 16. When the handle 14 is pushed, the sludge support 7 is compressed into a straight line shape under the action of the front sliding sleeve 12 and the rear sliding sleeve 8, causing the flexible support cloth 10 to gradually retract. At this time, the flexible support cloth 10 is close to the solid surface of the sludge in the groove 16, realizing the collection of samples; when the handle 14 is pulled back, the sludge support 7 gradually unfolds into a V-shape under the support of the front sliding sleeve 12 and the rear sliding sleeve 8, as well as the resistance of the collected sample, driving the flexible support cloth 10 to gradually unfold and gradually scrape it to the sludge discharge port 2 for discharge, completing the sample collection process.

[0063] Compared with the prior art, this application has the following technical effects:

[0064] In this application, when the handle moves backward, the flexible support cloth of the skeleton support is opened by the resistance of the dewatered sludge solids falling into the internal groove and the thrust of the rear sliding sleeve. During the backward movement, the flexible support cloth scrapes the sludge sample. During the sampling process, by repeatedly pushing and pulling the handle, the front push rod, the rear push rod and the skeleton support are driven to perform periodic reciprocating motion, so that the flexible support cloth unfolds or contracts under the action of the skeleton support. The collection of dewatered sludge samples can be completed through a simple push and pull action of the handle, which not only reduces the time and effort required in the operation process and greatly improves the sampling efficiency, but also improves the continuity and consistency of sampling.

[0065] In this application, the fixing ring installed in the groove at the edge of the hinge interface is covered by a rubber ring, which can effectively reduce frictional damage between the bone rod support and the internal groove of the sampling tube, improve the durability and operational stability of the device, and thus extend the service life of the device.

[0066] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. The preferred embodiments have been described in detail. Those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application, and all such modifications and substitutions should be covered within the scope of the claims of this application.
