Description

Technical Field

[0001] The utility model relates to the technical field of vacuum repair equipment, in particular to a semi-vacuum bamboo slip repair device. Background Art

[0002] my country is the earliest country to use paper. In the early history when paper was not invented and used, the ancients used bamboo slips, bones, rocks, etc. to record important historical text information. Among them, bamboo slips were used to record the thoughts of the predecessors and the country's policies for a long time. Due to the changes of countries, many historical documents have not been preserved intact. Some historical omissions can only be completed through bamboo slips unearthed by archaeologists. The bamboo slips were buried underground for a long time, and the attached peat made it impossible to directly decipher the handwriting. The twisted and deformed bamboo slips were very fragile and were easily oxidized and damaged when exposed to the air for a long time. This resulted in a certain amount of patience and technology required for the restoration and interpretation of the bamboo slips. The traditional restoration of bamboo slips is to soak the extracted bamboo slips in a prepared medicinal solution. Waiting for the deformed bamboo slips to extend and recover is a very long process. This requires a large number of bamboo slips to wait for a long time. Many bamboo slips may not be deciphered because of the long waiting time for restoration. This has caused irreversible losses to the completion of history and the restoration of cultural relics. Therefore, how to solve the above-mentioned problems has become a difficult problem that needs to be solved urgently. Utility Model Content

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a semi-vacuum bamboo slips repair device, comprising a repair placement groove, a liquid storage box body is provided at the bottom of the repair placement groove, a pressure relief solenoid valve is provided on one side of the bottom of the repair placement groove, the top of the pressure relief solenoid valve extends to the inside of the repair placement groove, the bottom of the pressure relief solenoid valve extends to the inside of the liquid storage box body, a sealing groove is provided at the top of the side wall of the repair placement groove, a transparent cover plate is movably connected to the top of the sealing groove, the side of the repair placement groove is connected to a pump pressure drive through a pump pressure solenoid valve, a manual control panel is provided at the top of the pump pressure drive, and the manual control panel is respectively connected to the pressure relief solenoid valve and the pump pressure solenoid valve through cables.

[0005] Preferably, a filter partition screen is provided inside the liquid storage box, a liquid injection port is provided at the top end of the side surface of the liquid storage box, and a sewage discharge port is provided at the bottom end of the side surface of the liquid storage box.

[0006] Preferably, a cover lifting handle is provided at the top of the transparent cover, and a beveled surface is provided at the bottom end of the side surface of the transparent cover corresponding to the sealing bevel.

[0007] Preferably, an air intake three-way joint is provided on one side of the pump pressure drive, an air intake filter is provided on the outside of one end of the air intake three-way joint, the other end of the air intake three-way joint passes through a water supply solenoid valve, the bottom end of the water supply solenoid valve extends to the inside of the liquid storage tank, and the water supply solenoid valve is connected to the manual control panel via a cable.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] (1) The utility model has a simple structure and is convenient and practical to operate. It can perform semi-vacuum immersion repair on oxidized bamboo slips, solving the technical problem that bamboo slips are prone to breakage and deformation due to long-term contact with air. The equipment can shorten the time for stretching and restoring bamboo slips by controlling the pressure. The original several hours of waiting for restoration can be shortened to dozens of minutes. The liquid medicine required for immersion and extension can be filtered and reused, which can greatly reduce the cost of bamboo slip immersion repair.

[0010] (2) The repair placement tank can be used to place bamboo slips. The liquid storage box is divided into two spaces. One space is for storing filtered soaking liquid, and the other space is for storing soaking liquid containing impurities generated by repairing bamboo slips. When a single batch of repairs is gradually completed and the bamboo slips are taken out, the pressure relief solenoid valve can be opened to allow the waste liquid generated by the last treatment to flow into the liquid storage box. The repair placement tank can be combined with a transparent cover to form a relatively closed space to facilitate accurate control of the pressure of the repair process. At the same time, the transparent cover also allows the operator to observe the extension and restoration progress of the bamboo slips at any time.

[0011] (3) The pump pressure solenoid valve can prevent the entry of air when there is no need to pressurize or introduce liquid medicine. The manual control panel allows the staff to control the extended recovery pressure, as well as the export and import of liquid medicine. The filter partition screen can filter out most of the particulate impurities in the waste liquid. The liquid medicine used multiple times can be exported through the sewage port, and the new liquid medicine can be added into the liquid storage tank through the liquid injection port.

[0012] (4) The chamfered surface of the groove can fit well with the sealing groove to ensure the stability of the pressure inside the repair placement tank. The air inlet three-way joint and the water supply solenoid valve can be driven by the pump pressure to inhale the liquid required for the extended repair. The water supply solenoid valve can also be closed and the air can be extracted or introduced through the air inlet filter. BRIEF DESCRIPTION OF THE DRAWINGS
