Description

Technical Field

[0001] The present application belongs to the technical field of environmental sampling equipment, and in particular relates to a sampling device for dewatered sludge. Background Art

[0002] With the gradual acceleration of urban sewage treatment facility construction and the increasing rate of centralized sewage treatment, the amount of sludge generated in the sewage treatment industry has also increased dramatically. The treatment of sludge follows the principle of "reduction". Dehydration operations must be performed to reduce the moisture content of the sludge before it can enter the next treatment link. Sampling of dehydrated sludge is a necessary step for subsequent testing and analysis.

[0003] At present, the traditional sampling tool for dewatered sludge is a thin rod with a slot. When sampling, the operator inserts the thin rod under the dewatered sludge discharge hopper to capture the fallen sludge sample, and then scrapes the sludge into the bucket for collection. However, the traditional manual sampling method has many limitations in practice, which are mainly manifested in the following two aspects:

[0004] 1. Difficult operation: The whole sampling process not only requires the operator to complete the actions of inserting the rod, extracting, scraping the sample one by one, but also consumes a lot of physical energy and easily causes fatigue. Especially when frequent sampling or large-scale sample processing is required, the workload is more obvious.

[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, and has low efficiency when collecting large amounts of sludge samples.

[0006] Therefore, developing a dewatered sludge sampling device that improves the efficiency of sludge sampling and enhances operational convenience has become a technical problem that needs to be urgently solved by those skilled in the art. Summary of the invention

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

[0008] To solve the above technical problems, this application is implemented through the following technical solutions:

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

[0010] A sampling tube shell, wherein a receiving space is provided inside the sampling tube shell and a sludge discharge port is provided on the surface of the sampling tube shell;

[0011] A concave platform is connected to one end of the sampling tube housing, and a fixing through hole is opened inside the concave platform;

[0012] A push rod assembly, which passes through the fixing through hole and is arranged in the accommodation space;

[0013] The push rod assembly is also fixedly connected to a limiting block;

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

[0015] A bone rod support is installed in the middle of the sliding sleeve assembly, and a flexible supporting 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 bracket, 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 arranged in the accommodating space.

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

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

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

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

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

[0022] Furthermore, one end of the flexible supporting cloth is adhered to the adhesive portion of the front sliding sleeve, and the other end thereof is adhered to the surface of the bone rod support.

[0023] Furthermore, the limit block includes a rear limit block fixedly connected to the rear push rod and a front limit block sleeved on the front push rod and located behind the rear sliding sleeve, wherein the rear limit 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 bracket is acted upon by the rear sliding sleeve to retract backward, driving the flexible support cloth supported by it to retract until the rear limit block collides with the front limit block; when the handle moves backward, the bone rod bracket is subjected to the resistance of the sludge, gradually opening the flexible support cloth, thereby scraping the sludge solids and allowing the sample to be discharged and collected from the sludge discharge port.

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

[0026] In the present application, when the handle of the bone rod bracket moves backward, the flexible support cloth is opened by the resistance of the dehydrated sludge solids falling in the internal groove and the thrust of the rear sliding sleeve, and the flexible support cloth realizes the scraping of the sludge sample during the backward movement; during the sampling process, the front push rod, the rear push rod and the bone rod bracket are driven to perform periodic reciprocating motion by repeatedly pushing and pulling the handle, so that the flexible support cloth is expanded or contracted under the drive of the bone rod bracket; the collection of dehydrated sludge samples can be completed by simple push-pull action of the handle, which not only reduces the time-consuming and labor-intensive problems in the operation process, greatly improves the sampling efficiency, but also improves the continuity and consistency of sampling.

[0027] In the present application, the fixed ring installed in the groove at the edge of the hinge is covered with a rubber ring, which can effectively reduce the friction damage between the bone rod bracket 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.

The material of the flexible support cloth 10 can be selected from corrosion-resistant materials of different thicknesses to meet the sampling requirements of different types of sludge, which is not specifically limited in this embodiment.

[0045] Further, 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 rod bracket 7, the other end of the front push rod 18 is connected to the rear push rod 6, and one end of the rear push rod 6 passes through the fixing through hole 5 and is arranged in the accommodating space 6. The above arrangement is conducive to ensuring that the movement direction of the push rod is stable.

[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 operated to move forward, the rear push rod 6 and the front push rod 18 move forward, so that the bone rod bracket 7 gradually contracts and pulls the flexible support cloth 10, and the flexible support cloth 10 is subjected to the resistance of the sludge sample falling into the accommodating space 16, and the flexible support cloth 10 is gradually closed and retracted.

When the handle 14 is pushed, the skeleton rod support 7 is compressed into a "one" shape under the action of the front sliding sleeve 12 and the rear sliding sleeve 8, so that the flexible support cloth 10 is gradually retracted. At this time, the flexible support cloth 10 is close to the solid surface of the sludge in the groove 16 to realize the collection of the sample; when the handle 14 is pulled back, the skeleton rod support 7 is supported by the front sliding sleeve 12 and the rear sliding sleeve 8, and the resistance of the collected sample, and gradually expands into a "V" shape, driving the flexible support cloth 10 to gradually expand, gradually scraping it to the sludge discharge port 2 for discharge, and completing the sample sampling process.
