Description

Technical Field

[0001] The utility model belongs to the technical field of slag sampling, and in particular relates to a slag sampler suitable for a garbage incineration power plant. Background Art

[0002] A waste incineration power plant is a power plant that mainly treats waste by incineration. Unlike conventional thermal power plants that aim to generate electricity, determining whether domestic waste is burnt out is done by detecting the carbon content in the slag. The problem that the utility model needs to solve is to sample the slag conveniently, quickly and safely. There is no special slag sampler for waste incineration power plants in the prior art.

[0003] Chinese patent application (202320250219.1) discloses a portable slag sampler, including a sleeve, a connecting rod is fixedly installed on the top of the sleeve, a handle is fixedly installed on the top of the connecting rod, a heat insulation cover plate is fixedly installed on the outside of the connecting rod, an adjustment assembly is fixedly installed on the inner wall of the sleeve, a bevel gear is fixedly installed on the outside of the adjustment assembly, a driven rod is fixedly installed on the inside of the bevel gear, a threaded rotating rod is fixedly installed on the bottom of the driven rod, a moving assembly is threadedly installed on the outside of the threaded rotating rod, a telescopic rod is fixedly installed on the back of the moving assembly, and a sampling shovel head is fixedly installed on the bottom of the telescopic rod.

[0004] The sampler of the prior art cannot meet the requirements for sampling slag in the slag channel of the waste incineration power plant. Since the front shovel head is small, it cannot effectively catch the falling slag, and the efficiency is low. In addition, the slag may contain large objects. The connecting rods of the sampler are not strong enough and can be easily damaged by the slag. Although the heat insulation cover plate can effectively prevent burns, its shape is irregular and the sampling port cannot be effectively sealed during the sampling process. During the slag discharge process, the sampling port is under positive pressure. If it cannot be sealed, the hot gas from the slag will escape, posing a safety hazard. Utility Model Content

[0005] The technical problem to be solved by the utility model is to solve the problem caused by sludge splashing, and to provide a slag sampler suitable for a waste incineration power plant which has a compact structure, is easy to use, has high reliability and low cost.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A slag sampler suitable for a waste incineration power plant comprises: a sampler body, a sealing flange, a handle, a counterweight and a connecting rod; one side of the sealing flange is connected and fixed to the rear end of the sampler body, and the rear end of the sampler body is provided with a counterweight connected and fixed to the sealing flange, the counterweight is used to achieve the balance of the sampler body in the slag channel of the waste incinerator, the other side of the sealing flange is connected and fixed to the front end of the connecting rod, and the rear end of the connecting rod is provided with a handle to facilitate the movement of the slag sampler; when slag sampling is performed, the sealing flange is sealed and connected to the sampling port of the slag channel of the waste incinerator, and the front end of the sampler body spans the slag channel to receive the slag.

[0008] As a further improvement of the present invention, a handle is provided on the sampler body, and the distance between the handle and the rear end of the sampler body is 1 / 3 of the total length of the sampler body.

[0009] As a further improvement of the utility model, the sampler body is an open semicircular tubular structure.

[0010] As a further improvement of the present invention, the handle is an arc-shaped structure, and the handle is welded to the sampler body.

[0011] As a further improvement of the utility model, a plurality of bolt holes are evenly distributed on the sealing flange to realize a detachable connection between the sealing flange and the sampling port of the slag channel of the waste incinerator.

[0012] As a further improvement of the utility model, a non-slip rubber sleeve is provided on the handle.

[0013] As a further improvement of the utility model, the sampler body and the handle are both made of manganese steel material.

[0014] As a further improvement of the present invention, the total length of the sampler body is 1000±10 mm.

[0015] Compared with the prior art, the advantages of the utility model are:

[0016] The utility model is suitable for the slag sampler of the waste incineration power plant. Since the waste incineration power plant detects whether the waste is burned out by calculating the thermal loss rate of the slag by testing, the sampling position of the slag can only be in the slag channel. The slag falls from the burning grate section through the slag channel and then enters the slag discharger. In this process, the kinetic energy generated by the slag falling is relatively large, and the traditional slag sampling device is easily damaged by the slag. The sampler made of manganese steel in the utility model has the advantages of high strength, high wear resistance, high shock resistance, etc., and the slag can be conveniently and quickly taken out from the slag channel. At the same time, the center of gravity of the entire sampler is adjusted to the counterweight fulcrum by designing a counterweight block, thereby increasing the stability of the sampler. Moreover, the sealing flange can be fixedly sealed with the sampling port flange during sampling to prevent the high-temperature hot gas generated by the slag falling during the sampling process from escaping, thereby eliminating the safety hazards during the sampling process.

[0019] The present invention is further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0020] Example

[0021] like Figure 1 As shown, the slag sampler of the utility model suitable for a waste incineration power plant comprises: a sampler body 1, a sealing flange 3, a handle 4, a counterweight 5 and a connecting rod 6. One side of the sealing flange 3 is connected and fixed to the tail end of the sampler body 1, and the tail end of the sampler body 1 is provided with a counterweight 5 connected and fixed to the sealing flange 3, and the counterweight 5 is used to adjust the center of gravity position of the sampler to achieve the balance of the sampler body 1 in the slag channel of the waste incinerator. The other side of the sealing flange 3 is connected and fixed to the front end of the connecting rod 6, and the tail end of the connecting rod 6 is provided with a handle 4, which can facilitate the sampler to quickly insert the sampler into the sampling port. A plurality of bolt holes 31 are evenly distributed on the sealing flange 3 to achieve a detachable connection between the sealing flange 3 and the sampling port of the slag channel of the waste incinerator. When slag sampling is performed, the sealing flange 3 is sealed and connected to the sampling port of the slag channel of the waste incinerator, and the front end of the sampler body 1 spans the slag channel to receive the slag. The sampler does not need to be placed in the slag channel all the time. It only needs to be inserted into the sampling port on the slag channel when sampling. The slag can be taken out in small quantities and multiple times in a short period of time.

[0022] In this embodiment, a handle 2 is provided on the sampler body 1. The total length of the sampler body 1 is 1000, and the sampling area is large, so as to obtain as many slag samples as possible. The distance between the handle 2 and the rear end of the sampler body 1 is 1 / 3 of the total length of the sampler body 1, and the handle 2 facilitates the movement of the sampler.

[0023] Furthermore, the sampler body 1 is an open semicircular tubular structure, the handle 2 is an arc-shaped structure, and the handle 2 is welded to the sampler body 1, which has a simple structure and reliable connection. The sampler body 1 and the handle 2 are both made of manganese steel.

[0024] Since the kinetic energy generated by the falling slag during the sampling process is relatively large, the sampler generally made of carbon steel is easily bent by the slag, resulting in a high failure rate of the sampler. In the present embodiment, the material of the sampler body 1 is manganese steel, which has the characteristics of high hardness, high shock resistance, high wear resistance, etc., and can be well adapted to the slag channel environment. An arc-shaped handle 2 is provided at a position one-third of the total length of the sampler body 1, and its material is also manganese steel, and its size and curvature are the same as those of the sampler body 1; the purpose of providing the handle 2 is that the length of the sampler body 1 is as long as 1000mm, and when fully inserted, it can just reach the center of the slag channel, ensuring the rationality of the sampling, and the handle 2 is convenient for the sampling personnel to operate independently, and the slag can be poured into the container conveniently and quickly.

[0025] Since the sampler body 1 is 1000mm long and made of manganese steel, its own weight is relatively large. If it is directly inserted into the slag channel, its own weight will cause the sampler to tilt and affect the sampling efficiency. In severe cases, it may even cause the sampler to be damaged and fall into the slag discharger, causing the slag discharger to malfunction. Therefore, a counterweight is designed at the position where the end of the sampler body 1 contacts the slag channel. The key is to reasonably select a counterweight of equivalent weight according to the weight of the sampler body 1 and add it to its end position; the counterweight 5 is welded to the end of the sampler body 1 by welding, in order to shift the center of gravity of the entire sampler to the counterweight 5. The counterweight 5 is connected to the sealing flange 3, which is a circular flange with the same size as the sampling port flange. The sealing flange 3 is provided with bolt holes 31, and its size and position are the same as the sampling port flange. The purpose of designing the bolt hole is that when the sampler is fully inserted into the sampling port, the sealing flange 3 can be docked with the sampling port flange and fixed with bolts. It can ensure that the high-temperature hot gas caused by the falling slag will not escape from the gap of the sampling port during the sampling process, thus protecting the sampling personnel. At the same time, the sampler can be fully fixed at the sampling port by bolts to avoid shaking of the sampler during the sampling process and improve the safety of sampling.

[0026] In this embodiment, the handle 4 is provided with an anti-skid rubber sleeve, which can provide a certain heat insulation effect and also prevent the sampler from falling due to hand slipping during the sampling process.

[0027] Before sampling, open the sampling port flange, insert the sampler body 1, and then connect the sampler sealing flange 3 and the sampling port flange with bolts. After confirming that the seal is in place, notify the operating personnel to drop the slag. After the slag is dropped, remove the bolts at the flange, and the sampler holds the handle 4 of the sampler to pull out the sampler. After pulling out one-third of the position, wear anti-scalding gloves, hold the handle 2 to pull out the sampler completely, and then pour the slag in the sampler into the pre-prepared container. Repeat this process several times until enough slag samples are obtained. After sampling, seal the sampling port.

[0028] Although the utility model is disclosed as above with preferred embodiments, it is not intended to limit the utility model. Any technician familiar with the art can use the above disclosed methods and technical contents to make many possible changes and modifications to the technical solution of the utility model without departing from the spirit and technical solution of the utility model, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent replacement, equivalent change and modification made to the above embodiments according to the technical essence of the utility model without departing from the content of the technical solution of the utility model still falls within the scope of protection of the technical solution of the utility model.
